Answer:
the best way to solve this is to have graph paper, so your numbers and points align. I have a model attached. the first point is hours slept 8. so on your graph go to 8 then across to 83, which is the test score. make a mark to represent this point. do this for all and it will create a line
Write an equation of the line in slope-intercept form.
Answer:
y = 2x+3
Step-by-step explanation:
You can see that the line crosses the y-axis at (0,3), so the y-intercept is 3.
To find the slope, compare the coordinates of the two points marked on the line, (0,3) and (-3,-3).
slope = Δy/Δx = ((-3)-3)/((-3)-0) = (-6)/(-3) = 2
Slope-intercept equation for line of slope 2 and y-intercept 3:
y = 2x+3
Which statement is true?
a.
All quadrilaterals are rectangles.
b.
All quadrilaterals are squares.
C.
All rectangles are quadrilaterals.
d.
All quadrilaterals are parallelograms.
Answer:
C. All rectangles are quadrilaterals.
Step-by-step explanation:
A quadrilateral is defined as a closed shape with four sides and angles. Therefore, a rectangle is a quadrilateral. A quadrilateral is the largest group of organization out of everything listed, so C must be correct because it is the only answer to sort a smaller group into a larger one.

Find the volume of Epcot Center in cubic ft. The diameter of the sphere is 165 ft. Use 3.14 to approximate pi and do not round your answer.
Answer:
28495.5 ft
Step-by-step explanation:
V=(4 /3)π(r^2)
r=radius=diameter/2
165/2=82.5
(4/3)3.14(82.5^2)
(4/3) x3.14x6806.25=28495.5ft

What is the length of BG and LB need help will mark Brainliest
we get x by setting up a proportion.
[tex]\frac{12}{2x+2}[/tex] = [tex]\frac{21}{5x-1}[/tex]
then we cross multiply.
12(5x−1) = 21(2x+2)
60x − 12 = 42x + 42
18x − 12 = 42
18x = 54
x = 3.
plug in 3 for x for LB, which is 2x + 2.
LB = 2(3) + 2 = 8
plug in 3 for x for BG, which is 5x - 1.
BG = 5(3) - 1 = 14

Ana found a job online with an annual salary of $32,000. What would her weekly salary, rounded to the nearest cent, be based on thi
Answer:
61538 cents
Step-by-step explanation:
Given
Annual salary = $32,000
Since 1 year = 52weeks
This means that she collected $32,000 in 52 weeks
52 weeks = 32000
We are to get the Ana weekly salary. say:
1 week = x
Divide both expressions:
52/1 = 32000/x
Cross multiply
52x = 32000
x = 32000/52
x = 615.38
Hence Ana's weekly salary will be $615..38 (61538 cents)

It is a little unclear when you state the problem what exactly is going on with that fraction. This is a common issue when you try to type up equations. On the right side, you have a fraction bar and then a bunch of stuff after it. We need to clear up what is supposed to be in the numerator and what is supposed to stay in the denominator. This is important not just for typing up questions on the internet to get help but in using your calculator as well. If what the equation means is that both "f" and "q+z" are in the denominator, but then on your calculator you type something 1 / 2 * f * ( q + z ), most calculators (e.g. TI 83/84 and almost any basic or scientific model) will interpret that as meaning only the 2 is on the bottom and the rest is on top.
If you meant the f and the q+z are on top, then Steve's answer is good.
If you meant the f and the q+z are supposed to be on the bottom, then we have a little bit different process.
First, write down the operations that are happening to q, and in what order they happen from inside out, that is, according to the regular PEMDAS rule:
1. z is added
2. 2f is multiplied
3. The result is divided into 1 (as opposed to being divided by 1).
So, to solve for q, we "invert" the order of operations and do the inverse operation of our 3 steps, and also in reverse order.
1. To get the big thing out of the denominator (Step 3), we will multiply both sides by 2f(q+z). Now we have:
C*2f(q+z) = 1, or as we normally write it,
2Cf(q+z) = 1
2. Now we have to adjust our steps just a little bit because we have the *C part too. So we will change Step 2 above to "2Cf is multiplied." We invert that by dividing, so we have:
q+z = 1/[2Cf]. Notice how I put brackets around the entire denominator so it's clear!
3. Finally to invert Step 1 we subtract z:
q = 1/[2Cf] - z

Use the distributive property to find the value of x.
-1.2(3 – x) = -1.8
-3.6 + 1.2x = -1.8
1.2x = 1.8
Answer:
-1.2(3 – x) = -1.8
x= 3/2
-3.6 + 1.2x = -1.8
x= 3/2
1.2x = 1.8
x= 3/2
