Answer:

y = - $\frac{2}{5}$ x + 9

Step-by-step explanation:

slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept

an equation with the SLOPE (m) of - $\frac{2}{5}$ and Y-INTERCEPT (b) of 9 would be

y = - $\frac{2}{5}$ x + 9

Write an expression that represents the area of the triangle with the base 2x to the power of 2 and height 3xy ( for any triangl

madam [21]

Since:
Area of a triangle = 1/2 * base * height

2x^2 ∗ 3xy/2 6x^3y/2 = 3x^3y/1

3x^3y/1

Therefore, the expression that represents the area of the triangle is 3x^3y/1.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Answer:

A. Circular base of the bucket

B. Bucket

Step-by-step explanation:

We are given that,

1. The dimensions of the rectangular prism are,

Length = 2 feet, Width = 3 feet and Height = 5 feet.

So, we have,

Area of the rectangular base = $Length\times Width$

i.e. Area of the rectangular base = $2\times 3$

i.e. Area of the rectangular base = 6 feet²

Also, we have,

Volume of the prism = $whl$

i.e. Volume of the prism = $3\times 5\times 2$

i.e. Volume of the prism = 30 feet³

2. The dimensions of the cylinder are given as,

Diameter = 3 feet i.e Radius = $\frac{3}{2}$ = 1.5 feet

Height = 5 feet

Then, we have,

Area of the circular base = $\pi r^2$

i.e. Area of the circular base = $\pi (1.5)^2$

i.e. Area of the circular base = $2.25\pi$

i.e. Area of the circular base = 7.07 feet²

Also, we have,

Volume of the cylinder = $\pi r^{2}h$

i.e. Volume of the cylinder = $\pi (1.5)^{2}\times 5$

i.e. Volume of the cylinder = $\pi 2.25\times 5$

i.e. Volume of the cylinder = $11.25\pi$

i.e. Volume of the cylinder = 35.34 feet³

PART A: Since we have,

Area of the rectangular base = 6 feet² < 7.07 feet² = Area of the circular base

Hence, the circular base of the bucket is larger in area.

PART B: We have,

Volume of the prism = 30 feet³ < 35.34 feet³ = Volume of the cylinder

Hence, the bucket is larger in volume.

The cylinder shown has a lateral surface area of about 750 square inches. Which answer is closest to the measure of the cylinder

Alchen [17]

Answer:

r ≈ 2.39 inches.

Step-by-step explanation:

I think your question is missed of key information of the height, allow me to add in and hope it will fit the original one.

The cylinder shown has a lateral surface area of about 750 square inches. Which answer is closest to the measure of the cylinder's radius? Use 3.14 to approximate pi. the height being 50 inches.

My answer:

Given that the lateral surface area of about 750 square inches and its height is 50 inches.

We have the formula ti find the surface area of the cylinder is:

S = h(2πr)

<=> 750 = 50*2*3.14*r

<=> r ≈ 2.39 inches.

Hope it will find you well.
