You draw two circles and convert the percentages to angles. 100% maps to 360°, to 50% maps to 180 degrees etc.

Then start by drawing a line from the origin of the circle to the top. This is your starting line, work your way clockwise to create pizza slices with the given angles you have just calculated.

In the double-bar graph, you create 5 categories (for each spending) and draw two bars above each category (one for each roommate).

For question b I would categorize the spendings into necessary and unnecessary, and then compare the amount of unnecessary spendings...

find the length of the base of a square pyramid if the volume is 1,024 cubic inches and has a height of 12 inches

Tju [1.3M]

Let 's x the length of the pyramid:
V=x²*h/3
V=1024 and h=12
So x²*12/3=1024
==>x²=1024*3/12
==>x²=256
==>x²=16²
==> x=16 for (x=-16 must be exclude <0)

A new car is purchased for 20000 dollars. The value of the car depreciates at 12. 5% per year. What will the value of the car be

Georgia [21]

To solve the problem we need to know about depreciation.

<h2>Formula of Depreciation</h2>

The formula of depreciation is given as,

$A = P(1-r)^t$

where,

A is the value of an object after t years of time,

P is the value of the object at the beginning, and

r is the rate of depreciation.

The value of the car after 11 years is $4,603.81.

<h2>Explanation</h2>

Given to us

Cost of Car at the beginning, p = $20,000
Rate of depreciation, r = 12.5%
Time, t = 11 years

<h3>Value of the car after 11 years</h3>

Substituting the values in the formula of depreciation,

$A = P(1-r)^t$

Value of the car after 11 years = $P(1-r)^n$

$= \$20,000(1-0.125)^{11}\\\\
= \$20,000\times 0.23\\\\
= \$4,603.822 \approx \$4,603.81$

Hence, the value of the car after 11 years is $4,603.81.

The graph below represents which of the following functions?

erica [24]

This is a more difficult one to explain. Let's start with the line to the right. It has a slope (m) of $\frac{-2}{2}$ = -1 and a y-intercept of +3 (continue the line to see where it crosses the y-axis). So, the equation of that line is: y = -x + 3 when x ≥ 2. This can also be written as y = 3 - x when x ≥ 2. The only option that has that equation is A.
