A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?

Answers

Answer:

523.3 cubic inches

Step-by-step explanation:

A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?

The shape of a basketball is spherical.

Hence:

The volume of a basketball = 4/3 × π × r³

From the question,

π = 3.14

r = radius = Diameter/2

r = 10 in/2 = 5 in

Hence:

The volume of the basketball

= 4/3 × 3.14 × 5³

= 1570 ÷ 3

= 523.33333333 cubic inches

Therefore, the approximate volume of the basketball = 523.3 cubic inches

Do you think it’s possible to have an excess of friends

Answers

I think it’s not good to have too many friends because you’ll feel anxious about spending enough time with each of them. Having too many relationships can also make one more depressed than if they were to have few close relationships. In my opinion, having a smaller group of close friends is better than having many friendships.

write an equation in a slope y-intercept form (y=mx+b) slope: -3 y-intercept: 7

Answers

Answer:

y=-3x+7

Step-by-step explanation:

Think of it like this, in y=mx+b, the m is representative for the slope and the b is representative of the y-intercept. In this case, the slope is -3, so you substitue the -3 with the m while the y-intercept is 7, so you replace the b with the 7.

Joe scored 10 more than half his normal average at the basketball game tonight. If he scored 24 times, what is his usual average?

Answers

Answer: His usual average = 28.

Step-by-step explanation:

Let x = usual average at the basketball game tonight.

As per given,

[tex]\dfrac{x}{2}+10=24[/tex]

Subtract 10 from both sides , we get

[tex]\dfrac{x}{2}+10-10=24-10\\\\\Rightarrow\ \dfrac{x}{2}=14\\\\\Rightarrow\ x=14\times2=28[/tex]

Hence, his usual average = 28.

If C=x^{2}+7C=x 2 +7 and D=3x^{2}-4x+3,D=3x 2 −4x+3, find an expression that equals 3C+3D3C+3D in standard form.

Answers

Answer:

3C + 3D = 12x² -12x + 30

Step-by-step explanation:

Given

C = x² + 7D = 3x² - 4x + 3

To determine

3C + 3D

The expression is given by

3C + 3D

substituting C = x² + 7 and D = 3x² - 4x + 3

= 3(x² + 7) + 3(3x² - 4x + 3)

= 3x² + 21 + 9x² - 12x + 9

= 12x² -12x + 30

Thus, the expression in standard form is:

3C + 3D = 12x² -12x + 30

The equation x + 8 = 12 represents the number of balloons Dylan needs to decorate a place for a party. Which number line shows how many more balloons Dylan needs?

Answers

Answer:

4 balloons

Step-by-step explanation:

According to the problem, the data given are as follows,

Equation given = x + 8 = 12

Here X is showing the number of balloons which Dylan more needs to decorate.

So, by solving the equation, we get

X + 8 = 12

( by taking 8 to RHS )

X = 12 - 8

X = 4

Hence, Dylan need 4 more balloons to decorate for a party.
