Answer:
(A)the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius
Step-by-step explanation:
Kareem plans to use the function [tex]C(F) = \dfrac59(F-32)[/tex] to convert temperature from degrees Fahrenheit to degrees Celsius.
The function gives a result in degrees Celsius. Therefore, 76.1 is in degree Fahrenheit and the result C(76.1) will be in degree Celsius.
Therefore, C(76.1) represents the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius.
The correct option is A.

15:PLEASE HELP Write 32 as a power of the base2
The ^ symbol means exponent. We have 2 as the base and 5 as the exponent. You might write it like this [tex]2^5[/tex] though 2^5 is more common with computers and keyboards.
Using your calculator, you should find that 2^5 = 2*2*2*2*2 = 32. We have five copies of the base 2 multiplied together.
You can use logs to determine how to write 32 as a base 2. You would do so like this
log(32)/log(2) = 5
it doesn't matter which base log you use. This is through the change of base formula.

Answer:
correct option is A: [tex]\frac{4}{10} \neq \frac{6}{14}[/tex]
Step-by-step explanation:
If the segment DE was parallel to the segment BC, we could use the Thales' theorem, where the ratio of one segment created in one side of the triangle over the whole side is the same ratio of one segment created in the other side over the whole side:
[tex]\frac{AD}{AB} = \frac{AE}{AC}[/tex]
Using the values given (AD = 4, AB = 6+4=10, AE = 6, AC = 8+6=14), we would have:
[tex]\frac{4}{10} = \frac{6}{14}[/tex]
[tex]4*14=6*10[/tex]
[tex]56=60[/tex]
This sentence is false, therefore the segments DE and BC are not parallel.
The inequation to prove this is the first one we used, using the "not equal" symbol:
[tex]\frac{4}{10} \neq \frac{6}{14}[/tex]
So the correct option is: A

10. A dice has 6 sides each from 1-6, rolling each time can give 6 different possible results, hence the chances of rolling a 2, 3, and 5 will be 1/6 respectively.
To roll a 2, 3, and 5 in order, which are independent events,
the required probability will be

Question #11:
Since the triangle is a right triangle we can use the pythagorean theorem:
[tex]B^{2}[/tex] + [tex]8^{2}[/tex] = [tex]15^{2}[/tex]
Working backwards we get that B is equal to 225 minus 64 which gets the square root of 161 or [tex]\sqrt{161}[/tex].
Question #12:
First we can start with finding the area of the rectangle in the trapezoid:
3 · 16 = 48
Next the two right triangles. 21 - 16 = 5 That is the length of the additional two triangles. Dividing 5 by two gets the base of one of them, but if we don't divide it by two we will be able to solve for both at the same time:
3 · 5 = 15
[tex]\frac{15}{2}[/tex] = 7.5
7.5 + 48 = 55.5

What is the third quartile for this data set?
Answer:
38
Step-by-step explanation:
Using the five number summary it is 38 since it is 75 percent of the sample
You have the correct answer. Nice work
==========================================================
Explanation:
If the values aren't sorted, then list them from smallest to largest. The values are already sorted for us, so we move onto the next step.
That next step is to find the median. The median is 29 because four values are smaller than it, and four values are larger than it. The value 29 is right in the middle. This value is in slot 5.
Next, split the data into two halves where L = {21,24,25,28} is the lower half and U = {35,37,39,42} is the upper half. As you can see, any value in set L is smaller than the median. While any value in set U is larger than the median.
The third quartile is the median of set U. We have four values in this set, so the median will be between slots 3 and 4 (between 37 and 39)
Average 37 and 39 to get (37+39)/2 = 38. We see that 38 is the midpoint of 37 and 39.
Therefore, the third quartile is 38.

Please just a quick question can, can you help me. The length of a rectangle is 8cm longer than its breadth, If the perimeter of the rectangle is 80 cm, find its length and breadth * choose one of the options 1.length = 16cm and breadth = 64cm 2.length = 16cm and breadth = 22cm 3.length = 24cm and breadth = 64cm 4.length = 24cm and breadth = 16cm
Answer:
Let's call the width x and the length x + 8. Perimeter can be calculated by multiplying the sum of the length and width by 2 so we can write:
2(x + x + 8) = 80
2(2x + 8) = 80
2x + 8 = 40
2x = 32
x = 16
This means that the length is 16 cm and the width is 24 cm.
Answer:
the area of rectangle is 384 sq cm, while the length of the rectangle is 24 cm and width of rectangle is 16 cm
Step-by-step explanation:
Let the breadth of the rectangle is x cm
Thus the length of the rectangle = (x + 8) cm
We know Perimeter = 2 (length + width)
Perimeter = 2 (x + 8 + x)
Perimeter = 2 (2x + 8)
Perimeter = 4x + 16 cm
4x + 16 = 80 cm
4x = 80 - 16
4x = 64
x = 64/4 cm
x = 16 cm
Thus the width of the rectangle is 16 cm
Length of the rectangle x + 8 = 16 + 8 = 24 cm
We know Area of rectangle = length × breadth
Area of rectangle = 24 × 16 = 384 sq cm

A coin- operated machine sells plastic rings. It contains 6 yellow rings, 11 blue rings, and 3 black rings. Sara puts a coin in the machine. Find the theoretical probability she gets a black ring. Express your answer as a decimal. If necessary, round your answer to the nearest tenth
Answer:
P(black) = 0.2
Step-by-step explanation:
Total number of rings
= 6 yellow + 11 blue + 3 black
= 20 rings.
P(black) = #black/#all = 3/20 = 0.15
Most people would round 0.15 to the nearest tenth as 0.2
It is not desirable in this cas to round to the tenth due to the 33% round-off error, but, what can you do.
Find all real zeros of the function Y = -9x-1
Answer:
x=-1/9; -1/9; (-1/9,0)
(each one is a different way to write the answer)a
Step-by-step explanation:
Zeros of a function are when the y-value of a point on a graph is equal to 0. Plugging in 0 for y in this equation of the function we get 0=-9x-1, which we can solve by adding 9x to both sides of the equation to get 0+9x=-9x+9x-1, or 9x=-1, and divide both sides by 9 to get x=-1/9

Possible values for the area A of the rectangle shown are 12 ≤ A ≤ 36. Write and solve a compound inequality to find the possible values of x. Are these values all viable in this situation?I really need help
Answer:
x can take any value and are viable in this situation if and only if it is a positive number
Step-by-step explanation:
We know that the area of a rectangle is given by:
A = x * y
So if we replace we have:
12 ≤ x * y ≤ 36
We divide by y, and we have:
12 / y ≤ x ≤ 36 / y
Which means that the value of x depends on y, that is to say if y is worth 1, the inequality would be:
12 ≤ x ≤ 36
In the event that y is equal to 2:
12/2 ≤ x ≤ 36/2
6 ≤ x ≤ 18
Which means, that depending on y, x can take any value and are viable in this situation if and only if it is a positive number.
The image of the function is missing, you can see it at the end of the answer.
For a rectangle of length L and width W, the area is given by:
A = L*W
We will find that the solution is: 3/2 ≤ x ≤ 11/2
Here we have:
L = 3
W = 2x + 1
Then the area equation is:
A = 3*(2x + 1) = 6x + 3
And we also have the inequality:
12 ≤ A ≤ 36
Replacing A with the equation we get:
12 ≤ 6x + 3 ≤ 36
Now we solve this for x:
12 - 3 ≤ 6x ≤ 36 - 3
9 ≤ 6x ≤ 33
Now we divide both sides by 6.
9/6 ≤ x ≤ 33/6
3/2 ≤ x ≤ 11/2

I need this ASAP! When David was asked how old he was, he said: "I'm three times younger than my dad, but twice as old as Rebecca." Then little Rebecca ran up to him and declared "I am 30 years younger than my dad." How old is David?
Answer:
David is 12 years old.
Step-by-step explanation:
Let r = Rebecca's age
Let d = David's age
let p = Dad's age
David is 3 times as younger than his dad:
d = [tex]\frac{p}{3}[/tex]
David is 2 times older than Rebecca:
d = 2r
Rebecca is 30 years younger than the dad:
r = p-30
All three equations can be solved by a system
2r = [tex]\frac{p}{3}[/tex]
r = p-30
multiplying r = p-30 by negative 2 and adding it to 2r = [tex]\frac{p}{3}[/tex]
0 = (-2p + p/3) + 60
multiplying new equation by 3
0 = (-6p + p) + 180
5p = 180
p = 36
d = 36/3 = 12
What is the area of the square adjacent to the third side of the triangle?
Answer:
The area of the square adjacent to the third side of the triangle is 11 units²
Step-by-step explanation:
We are given the area of two squares, one being 33 units² the other 44 units². A square is present with all sides being equal, and hence the length of the square present with an area of 33 units² say, should be x² = 33 - if x = the length of one side. Let's make it so that this side belongs to the side of the triangle, to our convenience,
x² = 33,
x = [tex]\sqrt{33}[/tex] .... this is the length of the square, but also a leg of the triangle. Let's calculate the length of the square present with an area of 44 units². This would also be the hypotenuse of the triangle.
x² = 44,
x = [tex]\sqrt{44}[/tex] .... applying pythagorean theorem we should receive the length of a side of the unknown square area. By taking this length to the power of two, we can calculate the square's area, and hence get our solution.
Let x = the length of the side of the unknown square's area -
[tex]\sqrt{(44)}^2[/tex] = [tex]x^2[/tex] + [tex]\sqrt{33}^2[/tex],
x = [tex]\sqrt{11}[/tex] ... And [tex]\sqrt{11}[/tex] squared is 11, making the area of this square 11 units².
Answer:
11 units²Step-by-step explanation:
If the triangle is right then area of square adjacent to the longest side is equal to sum of areas of squares adjacent to its other sides. (As in Pythagorean theorem)
So:
33 units² + ? = 44 units²
? = 44 units² - 33 units²
? = 11 units²
Determine the measure of the interior angle at vertex D.
Answer:
162°
Step-by-step explanation:
This is a hexagon, so the sum of the angle measures will be 720°
Add up the measures
40x=720
Divide
X=18
Multiply by 9 to find angle of D
9*18=162
The measure of the interior angle at vertex D is 162°. Hence, option B. is the right choice.
What are polygons?Polygons are closed plane figures formed by the intersection of 3 or more non-collinear line segments.
What is the sum of all interior angles of a polygon?The sum of interior angles of an n side polygon = (n-2)180°.
How do we solve the given question?We are given a 6 side polygon ABCDEF.
∴ n = 2.
The sum of interior angles of polygon ABCDEF = (6-2)180° = 4*180° = 720°.
The angles are 2x, 9x, 2x, 9x, 9x, and 9x.
Their sum = 2x + 9x + 2x + 9x + 9x + 9x = 40x.
This sum = The obtained sum
or, 40x = 720°
or, x = 720°/40 = 18°.
∴ Interior angle at vertex D = 9x = 9*18° = 162°. Hence, option B. is the right choice.
