Q1: The answer is A. pyramid.
A pyramid has one polygon base. A prism has two polygon bases. A cone has one circular base. A cylinder has two circular bases.

Q6: The answer is false.
Surface area of a rectangular prism is:
A = 2(wl + hl + hw)
A1 = 2(4*5 + 6*5 + 6*4) = 2(20+30+24) = 2*74 = 148
A2 = 2(6*4 + 5*4 + 5*6) = 2(24+20+30) = 2*74 = 148

Q7. The answer is A. 6 feet
The volume of rectangular prism is:
V = w * l * h
w = ?
So, just replace the knowing facts:
288 = w * 8 * 6
288 = w * 48
w = 288/48 = 6

Q8: The answer is 216 ft³
The volume of the cube is:
V = a³
Since a = 6, then:
V = 6³ = 216

I have to pay my friend $1 increased by 50% each day for 20 days. How much do I have to pay him at the end of the 20 days.

Radda [10]

So for this, you'll be using an exponential equation, which is y=ab^x (a = initial value, b = growth/decay).

Since you start off paying your friend $1, that will be your initial value. And since this is a 50% increase, you are to add 1 and 0.5 together (50% in decimal form), which is 1.5. That will be your b variable. And since # of days is the independent variable, that will be your x variable.

Using the previous info, this is our equation: y = 1(1.5)^20 . From here we can solve for the total cost (y).

Firstly, solve 1.5^20: y = 1(3325.26)

Next, multiply everything on the right side of the equation, and your answer will be (rounded to the hundreths): y = 3325.26

In context, at the end of the 20 days, you have to pay your friend $3325.26.

A rectangle is divided into equal squares. One row covers 1/8 of the whole rectangle. There are 3 squares in each row. How many

LenaWriter [7]

Answer:

There are 24 squares in the entire rectangle

Step-by-step explanation:

Trom the problem, we are given that one row covers 1/8 of the entire rectangle.

We are also told that this one row, contains three squares.

In other words, what this means is that three squares cover 1/8 of the entire rectangle.

The question is now if three squares cover only 1/8 of the rectangle, how many squares cover the whole rectangle.

In fraction, we can represent a whole using 1/1

We can set up a simple relation to this effect.

3 squares give 1/8 of the rectangle

x squares give 1/1 of the rectangle

cross multiplying, we have

x = 3 ÷(1/8) = 24

Therefore, there are 24 squares in the entire rectangle

If a calculator is sold for $19.20, then the revenue in dollars, R, generated by this item is given by the formula R=19.2q, whe

Alla [95]

The revenue generated will be $864 if 45 calculators are sold.

Step-by-step explanation:

Given,

Selling price of calculator = $19.20

Revenue generated = R = 19.2q

Where q represents the number of calculators sold.

If 45 calculators are sold, then

q = 45

Revenue generated = $19.2(45)$

Revenue generated = $864

The revenue generated will be $864 if 45 calculators are sold.
