PLEASE HELP ME! Sally is paid a fixed amount of money to walk her neighbor's dog every day after school. When she is paid each month, she puts aside $20 to spend and saves the remaining amount. Write an expression that represents the amount Sally will save in 6 months if she earns m dollars each month.
Answer: 6($m - $20)
Step-by-step explanation:
From the question, we are told that Sally earns m dollars each month to walk her neighbor's dog every day after school and that when she is paid each month, she puts aside $20 to spend and saves the remaining amount. This means that Sally saves:
$m - $20.
The expression that represents the amount Sally will save in 6 months will be so multiplied by the amount saved every month. This will be:
= 6($m - $20)
Answer:
Ok first of all. You cant be in highschool with this question. because this is a 6th grade question. Second that person who gave you that asnwer is wrong because thats not even the answer now I advise you to listen for future refrences.
Step-by-step explanation:
she is paid $65 and she saves $20 so subtract those numbers then you get $45 so that means she saves $20 and had $45 to spend. that means 20 times 6(months) is... $120 so $120 is your answer. But, to be more professional "Sally has saved $120 in 6 (Months.)
John cut a paper square with a perimeter of 18 inches into two rectangles. The perimeter of one of the rectangles is 10 inches. What is the perimeter of the second rectangle?
Answer:
13.5 inches
Step-by-step explanation:
Perimeter of the paper square = 18inches
Perimeter of a square = 4s
4s = 18 inches
s = 18/4 = 4.5 inches
Therefore, each side of the square = 4.5 inches.
When the square is cut into 2 rectangles,
The perimeter of one of the rectangles is 10 inches.
Perimeter of the second rectangle = 2L + 2W
Let the length of the rectangle (L) = one side of the square = 4.5 inches
Width of the Rectangle = Length of the square/2 = 4.5 inches/ 2 = 2.25
Perimeter of the second rectangle = 2(4.5) + 2(2.25)
= 9 + 4.5
= 13.5 inches

The world's oceans hold roughly 1.4 x 109 cubic kilometers of water. A typical bucket holds roughly 20,000 cubic centimeters of water. If there are 1015 cubic centimeters in a cubic kilometer, how many bucketloads would it take to empty the world's oceans?
Answer:
It'll take a bucket loads of [tex]7 * 10^{20}[/tex] to empty world's ocean
Step-by-step explanation:
Given
[tex]World\ Ocean: 1.4 * 10^9 km^3[/tex]
[tex]Bucket: 20,000 cm^3[/tex]
[tex]1 km^3 = 10^{15} cm^3[/tex]
To get the number of bucket loads, we simply divide the size of the ocean by the size of the bucket;
[tex]Number = \frac{Ocean\ Size}{Bucket\ Size}[/tex]
[tex]Number = \frac{1.4 * 10^9 km^3}{20,000cm^3}[/tex]
Expand the numerator
[tex]Number = \frac{1.4 * 10^9 * 1km^3}{20,000cm^3}[/tex]
Recall that [tex]1 km^3 = 10^{15} cm^3[/tex]
So, the expression becomes
[tex]Number = \frac{1.4 * 10^9 * 10^{15} cm^3}{20,000cm^3}[/tex]
Simplify the numerator using laws of indices
[tex]Number = \frac{1.4 * 10^{9+15} cm^3}{20,000cm^3}[/tex]
[tex]Number = \frac{1.4 * 10^{25} cm^3}{20,000cm^3}[/tex]
Expand the denominator
[tex]Number = \frac{1.4 * 10^{25} cm^3}{2 * 10,000cm^3}[/tex]
[tex]Number = \frac{1.4 * 10^{25} cm^3}{2 * 10^4\ cm^3}[/tex]
Split fraction
[tex]Number = \frac{1.4}{2} * \frac{10^{25} cm^3}{10^4\ cm^3}[/tex]
[tex]Number = 0.7 * \frac{10^{25}}{10^4\ }[/tex]
Simplify fraction using laws of indices
[tex]Number = 0.7 * 10^{25-4}[/tex]
[tex]Number = 0.7 * 10^{21}[/tex]
[tex]Number = 7 * 10^{20}[/tex]
Hence, it'll take a bucket loads of [tex]7 * 10^{20}[/tex] to empty world's ocean

Answer:
the last one
Step-by-step explanation:
the image of [0.1] is 1 using X and now it's X+3
so the image will be 4
Answer:
Last graph, 4, D
Step-by-step explanation:
g(x) = [X +3] is the graph we're looking for
g(x) = X would be a straight line with an equation of y=1x+0 and a slope of 1
So
g(x) = [X +3] would be adding 3 to the vertical asymptote of g(x)
or it would look like
y=1x+3
so the answer to this would be the line that has y = x+3
So the last one
Can someone please help me I really need help please help me thank you
Answer:
A
Step-by-step explanation:
Perpendicular lines always have the negative (opposite) reciprocal slope. Therefore, the slope of the line would be -2 because the reciprocal is just switching the numerator and denominator around (1/2 changes to 2/1 which is 2) and the negative means the opposite sign of which was originally given... i.e, since the 1/2 was positive, now it would be negative. That is why the slope is -2.
The equation of a line is y=mx+b with m representing the slope and b representing the y-intercept. Now to find the y-intercept, plug in the given components of the point (4,0) for the equation and solve for b (the y-intercept). Use 4 for x and 0 for y.
0=-2(4)+b
0=-8+b
8=b
Se desea plantar árboles a lo largo de un camino de 80m de longitud, a una distancia mínima entre ellos. Si dicha distancia de separación aumentará 6m, entonces el número de árboles necesarios disminuirá en 3. ¿Cuántos árboles serán plantados de la primera forma?
Answer: 8 arboles.
Step-by-step explanation:
Ok, el camino tiene 80m de longitud.
Si la distancia entre árbol y árbol es x metros, entonces entran:
N = 80m/x arboles.
Ahora, si x aumenta en 6m, entonces el numero de arboles se reduciría en 3, entonces tenemos el sistema de ecuaciones:
N = 80/x
N - 3 = 80/(x + 6)
Para resolver esto, el primer paso es remplazar la primera ecuación en la segunda:
N - 3 = 80/x - 3 = 80/(x +6)
Ahora podemos resolver esto para x.
80*(x + 6) - 3*x*(x +6) = 80x
80*x + 480 - 3*x^2 - 18*x - 80x = 0
-3*x^2 -18*x + 480 = 0
necesitamos resolver esa ecuación cuadrática, y sabemos que las soluciones son:
[tex]x = \frac{18 +-\sqrt{18^2 + 4*3*480} }{-2*3} = \frac{18 +-78}{-6}[/tex]
Entonces las dos soluciones son:
x = (18 +78)/-6 = -16
x = (18 - 78)/-6 = 10
La solución tiene que ser positiva, así que elegimos la segunda.
Esto quiere decir que la primera distancia es 10 metros, entonces el numero de arboles es:
N = 80m/10m = 8

Suppose f(x)=x^2. What is the graph of g(x)=f(3x)
Answer:
B
Step-by-step explanation:
We begin with the given function [tex]f(x)=x^2[/tex]
To find [tex]g(x)[/tex], we can plug [tex]3x[/tex] into the function [tex]f(x)=x^2[/tex]
[tex]f(x)=x^2\\\\f(3x)=(3x)^2\\\\f(3x)=9x^2\\\\g(x)=9x^2[/tex]
Now that we know the equation of [tex]g(x)[/tex], we can find the graph that is equivalent to it.
The only graph that is even close to the function [tex]g(x)=9x^2[/tex] is B, so that is our answer.

A grandfather wants to know the average height of all his grandchildren. He finds that the heights of his 9 grandchildren are given in inches by 63,71,60,59,74,60,60,75,58.
Answer:
The average height is 64.45 inches.
Step-by-step explanation:
Total number of children = 9 children
Heights in inches = 63,71,60,59,74,60,60,75,58.
The average height of grandchildren can be determined by adding all the given heights and then divide by the number of grandchildren.
Now if we add all the given heights of 9 children = 63 + 71 + 60 + 59 + 74 + 60 + 60 + 75 + 58 = 580
The average heights = 580 / 9 = 64.45 inches.

2 Kendal bought x boxes of cookies to bring to a party. Each box contains 12 cookies. She
decides to keep two boxes for herself. She brings 60 cookies to the party. Which equation
can be used to find the number of boxes, x, Kendal bought?
1) 2x - 12 - 60
3) 12x - 24 - 60
2) 12x-2-60
4) 24 - 12x - 60
Answer:
Hey there! The answer to your question will be below.
Step-by-step explanation:
The correct answer to your question is 12x - 24=60
So we know that 12x will be the number of cookies.
It says that she kept two boxes for herself, and than she took away 24 boxes which will leave us with 60.
Here is the work:
12 (x-2)= 60
12x-24=60
So the answer should be 12x -24 = 60

please help ! As an estimation we are told £3 is €4. Convert £64.60 to euros. Give your answer rounded to 2 DP.
Answer:
€86.13
Step-by-step explanation:
The computation is shown below:
According to the given question
The estimation we told is
£3 = €4
£ reflects the sign of the pound and "€" reflects the sign of Euro.
Therefore we apply the estimation we get
£1 = €
Now multiply both sides by 73.50.
£64.60= €
£64.60 = €
Therefore, the estimated value of £64.60 is €86.13 (£64.60 × 4 ÷ 3)

Assume that an opinion poll conducted in a 1998 congressional race found that on election eve, 54% of the voters supported Congressman Smith and 44% supported challenger Jones. Also assume that the poll had a /- 3% margin of error. What would the pollster be able to safely predict
Answer:
Congressman Smith will defeat Challenger Jones
Step-by-step explanation:
Since the poll has a +/- 3% margin of error, the minimum and maximum possible percentages for each candidate are:
(44% - 3%) ≤ Jones ≤ (44% + 3%)
41% ≤ Jones ≤ 47%
(54% - 3%) ≤ Smith ≤ (54% + 3%)
51% ≤ Smith ≤ 57%
This means that, even in the worst possible scenario for Congressman Smith, he would still beat Jones with 51% against 47% of the votes. The pollster can safely predict that Congressman Smith will defeat Challenger Jones .

Camila tried to shade only composite numbers on the hundred chart. What mistake did Camila make?
Answer:
B. 29 is prime, not composite
Step-by-step explanation:
A composite number, by definition, is any positive integer of which can be formed by the product of two or more numbers, and the integer must not be a prime number.
29 is a prime and not a composite number because it is only divisible by 1 and itself.
This is not same for 39 and 49.
39 can be divisible by 3, and 13, other than 1 and 39.
49 can be divisible by 7, other than 1 and itself.
Therefore, Camila made a mistake by shading 29 as a composite number.
The answer is: "B. 29 is prime, not composite".

draw the graph of the equation x+y=5and find the points were the line meets the x axis and y axis
Answer:
Use a graphing calculator.
Step-by-step explanation:
How to solve without a graphing calculator (if it's not allowed):
1) convert x+y= 5 to slope-intercept form. (right now it's in standard form.) We can do this by solving for y.
x+y=5 (subtract x from each side), y= -x +5
2) graph by hand using y=mx+b. From our equation, we can see that m= -1 and b=5. So, graph starting at 5, and go down one, over one, as far as you need to be able to draw the line through your points. Now, you can see that the y-intercept is 5 and the x-intercept is 5.
A recipe for tropical punch calls for 222 cups of pineapple juice and 333 cups of orange juice. Jo creates a drink by mixing 333 cups of pineapple juice with 444 cups of orange juice.
Answer:
Thus we can see that Amount of pineapple juice is more in Jo's drink And Amount of Orange juice is less in Jo'drink .
Step-by-step explanation:
If you want to see if Jo’s drink is equivalent you have to make equivalent ratios.
punch recipe : 2 cups : 3 cups
Jo’s : 3 cups : 4 cups
Let’s make the pineapple juice each 1 cup
punch recipe: 1 cup : cups?
Jo’s : 1 cup : cups?
we have to divide in order for this to work! since we divided 2 cups by 2 we divide 3.
punch recipe : 1 cup : 1.5
do the same thing for Jo’s. We divided 3 cups by 3 we divide 4 cups by 3 now.
jo’s recipe : 1 cup : 1.3
compare 1.5 is bigger than Jo’s recipe hers is not equivalen.
Answer is will have stronge pinnaple juice
