A​ 10-gal aquarium is 4 in. higher than it is wide. Its length is 17 ​in., and its volume is 4284 in.^3. What are the height and width of the​ aquarium?

Answers

Answer 1

Answer:

[tex]W = 18[/tex] -- Width

[tex]H = 14[/tex] --- Height

Step-by-step explanation:

Given

[tex]V = 4284[/tex] -- Volume

[tex]L = 17[/tex] -- Length

[tex]H = ??[/tex] -- Height

[tex]W = 4 + H[/tex] -- Width

Required:

Find the height and the width

Volume is calculated as:

[tex]V = LWH[/tex]

This gives:

[tex]4284 = 17 * (4+H) * H[/tex]

[tex]4284 = 17 * (4H+H^2)[/tex]

Open bracket

[tex]4284 = 17 * 4H+17*H^2[/tex]

[tex]4284 = 68H+17H^2[/tex]

Divide through by 17

[tex]252 = 4H+H^2[/tex]

Write as a quadratic expression

[tex]H^2 + 4H - 252 = 0[/tex]

Expand

[tex]H^2 + 18H - 14H - 252 = 0[/tex]

Factorize:

[tex]H(H + 18) - 14(H + 18) = 0[/tex]

Factor out H + 18

[tex](H - 14)(H + 18) = 0[/tex]

[tex]H -14 = 0[/tex] or [tex]H + 18 = 0[/tex]

[tex]H = 14[/tex] or [tex]H = -18[/tex]

But Height can not be negative. So:

[tex]H = 14[/tex]

Recall that:

[tex]W = 4 + H[/tex]

[tex]W = 4 + 14[/tex]

[tex]W = 18[/tex]

What is the total surface area of the square pyramid in square inches?
Height is 11 in. Base is 7 in. Side Length is 11.5

PLEASE DO THIS QUICKLY

Answers

Answer:

Step-by-step explanation:

I assume that "side length" means the slant height of one of the triangular faces.

area of a triangular face = ½(base)(side length) = ½(7)(11.5) = 40.25 in

lateral area = all four triangles = 161 in²

base area = 7² = 49 in²

total surface area = lateral area + base area = 161+49 = 210 in²

The area of the pyramid is  1.4625 ft²

What is a Square Pyramid?

If the base of the pyramid is in the shape of a square (base with 4 sides), then it is called a square pyramid. As the square has 4 sides, then the square pyramid has the following properties: No. of Faces: (4+1) = 5 No.of Vertices: (4+1)= 5 No. of Edges: 2(4) = 8

Given here: The height is 11, the base is 7 in, and the side length is 11.5 inches of a pyramid.

The surface area of a square pyramid is the sum of the areas of its square base and four triangular faces:

SA = BA + (4 × FA)

     =[tex]a^2+a\sqrt{a^2+4h^2}[/tex]

Where a= base length and height = h

Thus inputting the values we get

SA= 7²+7[tex]\sqrt{7^2+4.11^2}[/tex]

   =49+7√533

    =210.60 in²

Thus in ft.² we have 1.4625 ft²

If you are making a cake for a work potluck, and the recipe calls for 2 cups of flour to serve 8 people, how many cups of flour will you need in order to make a large enough cake to serve 30 people?

Answers

Answer:-

7.5 cups of flour is required for 30 people

Step-by-step explanation:-

2 cups = 8 people

x cups = 30 people

[ Cross multiply ]

=> 2×30 = x × 8

=> (2 × 30)/8 = x

=> 60/8 = x

=> 7.5 cups = x

Thus, for 30 people 7.5 cups of flour is required.

Translate the sentence into an equation. Five more than the quotient of a number and 6 is equal to 2. Use the variable w for the unknown number.​

Answers

Answer:

The equation that represents the sentence is W + 6 + 5 = 2.

Step-by-step explanation:

Since it is required to propose an equation that reflects that five more than the quotient of a number and 6 is equal to 2, using the variable W for the unknown number, the following equation must be performed to determine what the unknown number is:

W + 6 + 5 = 2

W = 2 - 5 - 6

W = -9

Therefore, the unknown number is -9.

[tex](x_2,y_2) = (5, -4)[/tex]

Required

Determine the equation

First, calculate the slope using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{-4 - (-4)}{5 -0}[/tex]

[tex]m = \frac{-4 +4}{5}[/tex]

[tex]m = \frac{0}{5}[/tex]

[tex]m = 0[/tex]

The equation is then calculated using:

[tex]y = m(x -x_1) + y_2[/tex]

This gives:

[tex]y = 0(x - 0)-4[/tex]

[tex]y = 0-4[/tex]

Use the table to write a linear function that relates Y to X

Answers

Answer:

y = 3/4x + 10

Step-by-step explanation:

The equation of a line is y = slope * x + y-intercept

To find the slope, you choose two points and do (y1-y2)/(x1-x2): Point 1 can be (4,13) and point 2 can be (8,16) so, slope = (13-16)/(4-8) = -3/-4 = 3/4

The y-intercept is the value of y when x is 0, so it would be 10.

Put it together and you get y = 3/4x + 10
