Step 1: Define

Identify

8x + 3y = 20

x + 4y = 17

(1, 4)

Step 2: Check

Plug and verify the coordinates is a solution.

∴ Since both equations work out, (1, 4) is a solution to the systems of equations.

Answer:

A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1

Step-by-step explanation:

Which statements are true? Mark all that apply. A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1. D If y³ = 16, the value of y is 2.

Solution:

a) y³ = 27

To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:

∛y³ = ∛27

y = 3

Option A is correct

b) y³ = 64

To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:

∛y³ = ∛64

y = 4

Option B is correct

c) y³ = 1

To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:

∛y³ = ∛1

y = 1

Option C is correct

d) y³ = 16

To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:

∛y³ = ∛16

y = 2.52

Option D is wrong

Answer:

Angle of elevation of sun = 59°

Step-by-step explanation:

Given:

Height of tree = 20 feet

Shadow of tree on ground = 12 feet

Find:

Angle of elevation of sun

Computation:

Height of tree = Perpendicular

Shadow of tree on ground = Base

Using trigonometry function;

Tanθ = Perpendicular / Base

Tanθ = 20 / 12

Tanθ = 1.66

Tanθ = Tan 59°

θ = 59°

So,

Angle of elevation of sun = 59°

Area required for circular hot tube = 6,218 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of circular hot tube = 89 inches

Value of π = 3.14

Find:

Area required for circular hot tube

Computation:

Radius of hot tube = Diameter / 2

Radius of hot tube = 89 / 2 inches

Area required for circular hot tube = Area of circle

Area of circle = πr²

Area required for circular hot tube = πr²

Area required for circular hot tube = (3.14)(89/2)²

Area required for circular hot tube = (3.14)(7921 / 4)

Area required for circular hot tube = (3.14)(1,980.25)

Area required for circular hot tube = 6,217.985

Area required for circular hot tube = 6,218 inch² (Approx.)

Answer:

do you mean 3.8765? cuz if you do its 4

Step-by-step explanation:

The rounded number to the nearest whole number is 4.

Rounding off is estimation. Estimating the actual number to its nearby number is called rounding off.

Given is a decimal number 3.8765 we need to round off to the nearest whole number,

3.8765 =

You rounded to the nearest ones place. The 3 in the ones place rounds up to 4 because the digit to the right in the tenths place is 8.

When the digit to the right is 5 or greater we round away from 0.

Hence, 3.8765 was rounded up and away from zero to 4.

Hence, the rounded number to the nearest whole number is 4.

Answer:

6000 m^3

Step-by-step explanation:

The basic formula for the area of a pyramid is 1/3 * b * h

where b is the base and h is the height.

The base is a square, so, we can find the area by squaring the side:

30^2 = 900.

Now, we can plug the values we have into the formula from above:

1/3 * 900 * 20
