Answer 1

Answer:

Part A:

6 feet

Part B:

Around 9.17 feet

Part C:

Around 3 feet

Step-by-step explanation:

Part A:

The Pythagorean Theorem (which is a^2 + b^2 = c^2), is the simpilist way to solve this. a = 8; c = 10. so, the problem becomes (64 + b^2 = 100). Subtract 64 from both sides to get (b^2 = 36). Square root both sides to get (b = 6).

Part B:

Using the same method, but with different measurements:

(a^2 + b^2 = c^2)

(16 + b^2 = 100)

(b^2 = 84)

(b = 9.17)

Part C:

The difference of 9.17 and 6 is 3.17. Therefore, the closest foot is 3. Hope this helps! Have a great day! :)

Answer 2

PART A uses Pythagoras. Because you are finding the short side you do 8 squared and 10 squared (100 and 64) and subtract them to get 36. You then do the square root of 36 to get 6 which is the answer!

3.) 6 to 5

Step-by-step explanation:

Unit rates are like ratios. It also means a rate of one to something. So 3.) 6 to 5 is correct

The answer is 2. 60 miles per hour.
Unit rate is a ratio that compares two different quantities with different units.
Choice 2 is the only right one since it’s miles per hour. Choice 1 and 3 are just simple ratios with no units.

A sculpture is made of solid nickel in the shape of a cone. The sculpture is 84 inches tall, and its base has a diameter of 16 inches. If nickel costs $2.25 per cubic inch, how much did the nickel for the sculpture cost?

Use 3.14 for pi, and do not round your answer.

Answers

The total cost of the nickel for the sculpture is $12,660.48.

We know that the volume of a cone is:

v = 1/3πr²h ......(i)

where r ⇒ radius of the cone

h ⇒ height of the cone

Now, as per the question,

r = diameter/2 = 16÷2 = 8 inches

h = 84 inches

Putting the values in equation (i)

v = 1/3 × 3.14 × (8)² × 84

v = 5626.88 cubic inch

The cost given for nickel = $2.25 per cubic inch

So, the total cost for the nickel used in making the sculpture:

the volume of cone × cost per cubic inch

5626.88 × 2.25 = $12,660.48

Therefore, the total cost for the nickel used is $12,660.48

Hii, does anyone know what the variables equal?

Answers

Answer:

a. 5d * 7g = 35dg

b. 12ab * 3cd = 36abcd

Step-by-step explanation:

To find the product of two or more terms, we can use the distributive property of multiplication. In part (a), we multiply the coefficients 5 and 7 to get 35, and we multiply the variables d and g to get dg. Therefore, the product of 5d and 7g is 35dg.

In part (b), we can multiply the coefficients 12 and 3 to get 36, and we can multiply the variables a, b, c, and d to get abcd. Therefore, the product of 12ab and 3cd is 36abcd.

Answer:

In these scenarios, it is not possible to find the values of the variables and the question is not asking you to do so

a. 5d x 7g = 35dg

b. 12ab x 3cd = 36abcd

What is the area of this trapezoid?

Enter your answer in the box.

Answers

Answer:

153 units squared

Step-by-step explanation:

first, multiply 10 x9 to find the area of the rectangle, which is 90

then find the area of the triangle. The formula for area of a triangle is

A=1/2bh

so, 7 x 9= 63 divided by 2 is 31.5

since there are 2, multiply 31.5 x 2= 63

add 63 to 90 which is 153

Answer: 153 sq. units

Step-by-step explanation:

Base a = 10

Base b = 7x2 = 24

Height = 9

area of trapezoid = 1/2 * (a+b) * h

= 10+24 * 9 /2

= 306/2 = 153

Maria’s current car gets 24 miles per gallon. Last year she drove 15,000 miles. Last year gas cost an average of $3.35
solve 1. How much did Maria spend for gas for her car last year?
solve 2. Maria is buying a new car that averages 32 miles per gallon. If she drives the car 15,000 miles in the next year and gas prices stay the same, how much will she spend for gas in the next year?
solve. 3 ) How much money will Maria save in gas costs in the next year by driving her new car as opposed to her old one?
solve 4. What percent decrease in gas costs for one year will Maria realize by driving her new car?

Answers

1) Last year, Maria spent $2093.75. Here's the equation to find that answer:

(a ÷ b) × c

a = 15,000b = 24c = 3.35

(15,000 ÷ 24) × 3.35

2) Same equation. (15,000 ÷ 32) × 3.35. The answer of this equation is 1570.3125, but that rounds to $1570.31.

3) This part represents a simple difference/subtraction problem. Since she spent $2093.75 last year, and will spend $1570.31 with a new car, she will save 523.44.

4) Using percent of change, the percent decrease Maria will realize in one year is 33.333%, or [tex]\frac{1}{3}[/tex].
