Marsha likes to take photos with her new camera.She already has 1427 photos. She just bought her camera 15 days ago and took pictures everyday.Approximately how many pictures did she take each day?
Answer:
About 95
Step-by-step explanation:
If she bought her camera 15 days ago, then you just divide 1427 by 15. You can't take parts of pictures, so it has to be a whole number, so you round.
Answer:
95.1333333333 you should probably round it but thats how many photos she took each day
Step-by-step explanation:
1427/15= photos taken each day

Three consecutive integers add up to 51. What are these integers
Let the three consecutive integers be x, x+1 and x+2.
According to the question, x+x+1+x+2=51
=>3x+3=51
=>3x+3-3=51-3
=>3x=48
=>x=16
Hence, first integer = 16,
second integer = 16 + 1 = 17 and
third integer = 16 + 2 = 18.

A turtle lives in a garden and a hedgehog lives in the woods. They leave their homes at the same time walk toward each other and meet in 5 hours. The turtle walks 10 meters per hour slower than the hedgehog. If the turtle had left home 4 1/2 hours earlier than the hedgehog had left his home, the two would meet 150m from the woods. Find the distance between the garden and the woods.
Answer:
The answer is 450
Step-by-step explanation:
I got this equation:
x- the speed in which the turtle walks
5x+5(x+10)=4.5x+150+x*(150)/(x+10)
I got x=40, x=-50/11, but you can't have negative speed, so the turtle's speed is 40 meters per hour. After that, I just plugged in x onto one of the expressions and got 450.
By solving a system of equations, we will see that the distance is 383m
How to find the distance between the garden and the woods?Let's define the speeds of the animals as:
St = speed of the turtle.Sh = speed of the hedgehog.We know that if they leave their houses at the same time, they meet after 5 hours, so we have:
(St + Sh)*5h = D
where D is the distance we want to find.
We also know that:
St = Sh - 10m/h
And if the turtle leaves 4.5 hours earlier, they meet at 150m from the woods.
This is written as:
St*9.5h + Sh*5h = D - 150m
So we need to solve a system of equations:
St*9.5h + Sh* = D - 150m
St = Sh - 10m/h
(St + Sh)*5h = D
Replacing the second equation into the other two we get:
(Sh - 10m/h + Sh)*5h = D
(Sh - 10m/h)*9.5h + Sh*T = D - 150m
Now we can find Sh on the second one.
Sh*14.5h = D - 150m + 95m
Sh = (D + 150m + 95m)/14.5h = D/14.5h + 16.9 m/h
Replacing that on the other equation we get:
(2*(16.9m/h + D/14.5h) - 10m/h )*5h = D
118.96m + D*(10/14.5) = D
118.96m = D*(1 - 10/14.5)
D = 118.96m/(1 - 10/14.5) = 383m
The distance is 383m

Plz help solve: Find the side length of a square with an area of 15/6 cm^2
Answer:
1.58 cm
Step-by-step explanation:
Area of a square = length ²
Area of the square = 15/6 cm²
Area of a square = length ²
15/6 = length²
Find the square root of both sides
√15/6 = √length²
√2.5 = length
1.58 cm = length
Alternatively,
√15/6 = √length²
√15/√6 = length
3.87 / 2.45 = length
1.58 cm = length
Therefore, side length of the square = 1.58 cm

Answer:
First, we can find the least common denominator for 8 and 3 which is 24.
5/8 = 15/24
1/3 = 8/24
Then we can divide 15/24 by 8/24 which is 2 1/4.
If we then do 16 divided by 2 1/4 we get 7 1/9

Generally the equation for Total pound of coffee W is mathematically given by
Total pound of coffee=Total amount spent/Rate

Selecting two marbles from a bag containing the numbers 2,4,6,8,10,12 (with replacement) what is the probability of selecting two numbers less than 10 ?
Given:
A bag containing the numbers 2,4,6,8,10,12.
To find:
The probability of selecting two numbers less than 10.
Solution:
We have,
Total numbers = 6
Numbers less than 10 are 2,4,6,8.
Numbers less than 10 = 4
Probability of getting a number less than 10 is:
[tex]P(\text{Less than 10})=\dfrac{\text{Numbers less than 10}}{\text{Total numbers}}[/tex]
[tex]P(\text{Less than 10})=\dfrac{4}{6}[/tex]
[tex]P(\text{Less than 10})=\dfrac{2}{3}[/tex]
We select the second number with replacement. So, the probability of second draw is same as the probability for first draw.
Probability of selecting two numbers less than 10 is:
[tex]\text{Required probability}=P(\text{Less than 10})\times P(\text{Less than 10})[/tex]
[tex]\text{Required probability}=\dfrac{2}{3}\times \dfrac{2}{3}[/tex]
[tex]\text{Required probability}=\dfrac{4}{9}[/tex]
Therefore, the probability of selecting two numbers less than 10 is [tex]\dfrac{4}{9}[/tex].

write the slope-intercept form of the equation of the line through the given points.
Answer:
y = 4x - 7 (Answer C)
Step-by-step explanation:
First find the slope of this line. Note that as we go from (2, 1) to (3, 5), x (the 'run') increases by 1 and y (the 'rise') increases by 4.
Thus, the slope, m, is
m = rise / run = 4/1, or m = 4.
Apply the point-slope form of the equation of a straight line, since we now have both the slope and two points on the line:
y - k = m(x - h) becomes y - 1 = 4(x - 2)
Solving for y, we get: y = 4x - 8 + 1, or y = 4x - 7 (Answer C)
Write the Standard Form equation of a line with a slope =2/3 and a y intercept if -4
Answer:
Assuming you meant to write -2/3 instead of =2/3, the answer is 2x+3y= -12

En el club de teatro asistieron 15 alumnos a clases .Si en total son 21 ¿ cual es la razon entre el total de alumnos y los ausentes
Answer:
La razón entre el total de alumnos y los ausentes es [tex]\frac{6}{21} =\frac{2}{7}[/tex]
Step-by-step explanation:
En el club de teatro asistieron 15 alumnos a clases. En total, son 21 alumnos. Entonces la cantidad de alumnos ausentes se calcula como la diferencia entre la cantidad total de alumnos y la cantidad de asistentes, esto es:
21 alumnos - 15 alumnos= 6 alumnos
La cantidad de alumnos ausentes es 6.
La razón es la comparación de dos cantidades y se mide como el cociente entre dos números o cantidades comparables entre sí, que se expresa como una fracción. Es decir, la razón entre 2 números a y b es el cociente [tex]\frac{a}{b}[/tex].
Entonces, la razón entre el total de alumnos y los ausentes es [tex]\frac{6}{21} =\frac{2}{7}[/tex]

Answer:
A u B = {1,3,5,7,9,11,13,15,17,19,23}
A n B = {5,7,11,13}
Step-by-step explanation:
The prime numbers between 4 and 25 are; 5, 7, 11 , 13 , 17 , 19 and 23
A = {5, 7,11, 13, 17, 19,23}
B are odd numbers less than 16
B = {1, 3 , 5,7,9,11,13,15}
The union of both is the list of all values present in both sets without repeating;
A u B = {1, 3, 5,7,9,11,13,15,17,19,23}
A n B is the set that contains values that are present in both sets
A n B = {5,7,11 , 13}

What is the surface area of a cylinder with a height of 20 meters and a diameter of 10 meters? O A) 1884 m2 OB) 863 m2 OC) 353.25 m2 OD) 785 m2
Answer:
785
Step-by-step explanation:
did the math in a calculator I got yoy
Answer:
D. 785
Step-by-step explanation:
the formula to find the surface area of a cylinder is A=2πrh+2πr^2
the diameter is a straight line through the center of a figure so half of that would be the radius and our diameter is 10 so the radius is 5
our height is 20 so now we put it into the equation it will look like this
2·π·5·20+2·π·5^2
once you do the math you will get 785.39816

Wendell is looking over some data regarding the strength, measured in Pascals (Pa), of some building materials and how the strength relates to the length. The data are represented by the exponential function f(x) = 2x, where x is the length. Explain how he can convert this equation to a logarithmic function when strength is 8 Pascals.
Step-by-step explanation:
f(x) = 2^x (this is exponential function)
f(x) = 8
the equation is :
2^x = 8
2^x = 2³
cross out 2
so, we get : x= 3
The conversion is given below.
x is 3.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = [tex]2^x[/tex]
f(x) = strength and x is the length.
Now,
Strength = 8
So,
8 = [tex]2^x[/tex]
Taking logs on both sides.
log 8 = x log 2
x = log 8 / log 2
x = log (8/2)
x = log 4
x = log [tex]2^2[/tex]
x = 2 log 2
or
2 x 2 x 2 = 2³ = 8
So,
8 = 2³
x = 3
Thus,
x = 3.
