Answer:
There were 86 problems on the test.
Step-by-step explanation:
72/87 = y/100
You use cross multiplication to solve. When you do this, you get the answer 86.75 problems, but since you can't have .75 of a problem, the answer is 86.

The diameter of a circle is 9.6 feet what is the area code ?
Answer:
Area = π[tex]4.8^{2}[/tex]
Step-by-step explanation:
In order to find the radius, you must divide the diameter by 2:
[tex]r = \frac{9.6}{2} = 4.8[/tex]
Area of a circle:
A = π[tex]4.8^{2}[/tex]
A = 72.38 ft^2

Find the equation of the line
passing through the points (5, 2)
and (10, 6).
y =
Xt
Answer:
y=4/5x-2
Step-by-step explanation:
here are the given points: (5,2) and (10,6)
First, let's find the slope, which is found with the equation (y2-y1)/(x2-x1)
so let's label the points
x1=5
y1=2
x2=10
y2=6
now we can substitute into the equation
m=(6-2)/(10-5)
subtract
m=4/5
so that means the slope is 4/5
Now, let's use point slope form, which is y-y1=m(x-x1) (m is the slope)
so let's substitute the numbers we know from earlier into the equation
y-2=4/5(x-5)
do distributive prop.
y-2=4/5x-4
add 2 to both sides
y=4/5x-2

What is the diameter of a sphere with a volume of 170m3
Find the product. Enter the answer in simplest form.
Answer:
5/2 or 2.5/2 and a half
Step-by-step explanation:
Turn 5 into a fraction :
5 = 5/1
Now you can multiply the two fractions together by multiplying the numerators together and multiplying the denominators together :
1/2 x 5/1 = 5/2 or 2.5/2 and a half

A cell phone plan charges $39.95 a month plus 15 cents per text message sent and 15 cents per text message received. Using s to represent the number of text messages sent in one month and r to represent the number of text messages received in one month, the following equation can be used to calculate the total monthly cost, c:c = 39.95 + 0.15(s + r)If it is known that the total monthly cost is $53.45 and 63 text messages were received, solve for s, the total number of text messages sent.

What is the GCF(Greatist common factor) of 8 and 176?
Brainlist for the correct answer!
Answer:
The GCF of 18 and 176 is 2
Step-by-step explanation:
To get the Greatest Common Factor (GCF) of 18 and 176 we need to factor each value first and then we choose all the copies of factors and multiply them:
18: 2 × 3 × 3
176: 2 × 2 × 2 × 2 × 11
GCF: 2
The Greatest Common Factor (GCF) is: 2
( the greatest common factor of 8 and 176 is 8 btw if anyone wanted to know. the author meant to say " of 18 and 176 ", not "of 8 and 176"... they said it in the comments of the question :] )
Find MZP. The diagram is not to scale.
Answer:
p= 50

what is the value of -6-(x+3)y when x = -5 and y = 2????
Answer:
-2
Step-by-step explanation:
Answer: -2
Step-by-step explanation:
Substitute -5 for x and 2 for y in the expression, which gives -6 minus the quantity -5+3, all divided by 2.
Then, use the order of operations to simplify the numerator of the expression. Finally, simplify the fraction, which gives -2. So, when x equals -5 and y equals 2, the expression is equal to -2.
Find the value of x in the triangle shown below.
X=____
Please help!!
Answer:
62
Step-by-step explanation:
the sum of all angles in a triangle should be 180°
180-56= 124
124÷2= 62
x= 62
Answer:
The sum of the interior angles of a triangle is 180°.
Two sides of the triangle is same, so the their corresponding angles will also be same.
[tex]x + x + 56 = 180 \\ 2x = 180 - 56 \\ 2x = 124 \\ \boxed{x = 62°}[/tex]
62° is the right answer.
