He needs to flip the equation. So the real answer is 5.49/10=0.549

**Answer:**

V = 4187 cubic units.

**Step-by-step explanation:**

Volume of a sphere = 4/3*π*r^3

Given: r = 10, π = 3.14

Volume of the sphere = 4/3*3.14*10^3

= 4/3*3.14*1000

= 4/3*3140

= 12560/3

V = 4186.66

When we round to the nearest whole number, we get V = 4187 cubic units.

Hope this will helpful.

Thank you.

V=πr^2(h/3)

V≈804.25

Since the height is 12, and radius is 8, take the radius and square it. 8 squared equals 64. Now, take the height (12) and divide that by three. This equals 4.

So Volume = Pi times 64 times 4. The answer should be 804.247. Once rounded, you should get 804.25

QUESTION POSTED AT 31/03/2020 - 10:38 AM

Get the area of the circle. Use this formula:

Area = * radius^2

We know the radius is 4 yards.

Area = 3.14 * 4^2

Area = 3.14 * 16

Area = 50.24

Now for the square. Double the radius to get the diameter to get the length of the side.

4 * 2 = 8

Formula for finding the area of a square is

Area = side^2

Area = 8^2

Area = 64

And because we only want to shaded portion, we will subtract the area of the circle from the square.

64 - 50.24 = 13.76

So, D) 13.76 square yards is the answer to this question.

QUESTION POSTED AT 30/03/2020 - 01:30 AM

(1) To find the angle between v and positive x-axis, we first determine the angle formed by v and the negative x-axis. Since v = (-7,8), its vertical measure y is 8 units and horizontal measure x is 7 units.

arctan(8/7) = 48.81°

Solving for angle between v and positive x-axis:

180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ

Calculating for the dot product of the vector:

v1 x v2 = -7*1 + 8*0 = -7

Calculating vector magnitude:

|v1| = √(-7²+8²) = √113

|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

arctan(8/7) = 48.81°

Solving for angle between v and positive x-axis:

180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ

Calculating for the dot product of the vector:

v1 x v2 = -7*1 + 8*0 = -7

Calculating vector magnitude:

|v1| = √(-7²+8²) = √113

|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

The area is 38 because whenever you have to find the area in an equation you always add up the total sides. The shape is a rectangle and the only numbers they give is 6 and 13 obviously the sides are equal so the opposite side of 13 is 13 and the opposite side of 6 is 6 because they're both a certain length. In total you add up all the sides 13 plus 13 is 26, 6 plus 6 is 12 , 26 plus 12 is 38

The perimeter is 78 because they only give you two number so whenever you do a perimeter in an equation you always have to remember to multiply. 13 multiplied by 6 is 78. Hope this helped ( :

Write 76% as a decimal and as a reduced fraction.

Decimal : 0.76

Fraction : 76/100, which then simplifies to 38/50, because you divide the numerator & denominator by 2. Then, you divide them by 2 again, and get 19/25.

Reduced Fraction : 19/25

2) Po messes up 4 out of every 10 moves.

So, to make this slightly easier, we're going to turn that (above) into a fraction!

Fraction : 4/10

Then, we turn it into a decimal.

To turn it into a decimal, multiply 4/10 by 10/10, so that the denominator is 100.

Fraction: 4/10 × 10/10 = 40/100

Decimal : Because the denominator is 100, all we have to do is add a decimal marking 2 places to the left of the last digit. (0.40)

Now, because we have our decimal, we simply say that the percentage is 40%.

Why? Because if the decimal is in the hundredths place, all you need to do is take the numbers on the right side of the decimal marking, and add a percentage sign to it.

~Hope I helped!~
