A basketball goal is 18 inches in diameter. A basketball has a diameter of about 9.6 inches. What is the difference in circumference between the goal and the center cross-section of a basketball?

Answers

The difference in circumference between the goal and the center cross-section of a basketball is 26.4inches.

It is given that

Diameter of a basketball goal = 18inches

So, the radius will be 18/2 = 9inches

What is the circumference of a circle?

It is the length of the outer periphery of a circle equals 2*π*r, where r is the radius of the circle.

Circumference of goal = 2*π*9 = 56.57inches

Diameter of basketball = 9.6inches

So, the radius of basketball will be 9.6/2 = 4.8 inches

Circumference of cross-section of basketball = 2*π*4.8 = 30.17inches

So, the difference in circumference between the goal and the center cross-section of a basketball = 56.57-30.17 = 26.4inches.

Therefore, difference in circumference between the goal and the center cross-section of a basketball is 26.4inches.

8.4 you hsve to subtract 18-9.6 and you get ur answer. let me know If you need anymore help

A: Miguel says that you can easily separate numbers divisible by 2 into two equal parts. Do you agree? Why or why not?B: Manny says that if Miguel is correct, then you can easily separate numbers divisible by 3 into three equal parts. Do you agree? Why or why not?

C: Lupe says that if any number is divisible by n, you can easily separate it into n equals parts. Do you agree with her? Explain.

Answers

Answer:

Step-by-step explanation:

A. Yes,Miguel is correct because all even numbers are the multiple of 2 and when we divide any even number resultant will be a whole number which represents the number of equal parts.

Example: 8 ÷ 2 = 4

B. Yes, Because all numbers which are multiple of 3, when divided by 3 resultant will be a whole number which represents the equal number of parts.

Example : 6 ÷ 3 = 2

C. Yes, Lupe is correct. When any number multiple of n is divided by n we get a whole number which represents the number of parts divided equally.

Example : 2n ÷ n = 2

A. Yes, the number 8 is divisible by 4. You can split it into two, 4 and 4.
B. Yes, the number 99 is divisible by 3, You can split it into three equal parts.
33,33, and 33.
C. Yes because it works like that for all of the numbers.
Hope this helps.

Can someone please help me with #10. i need the one with solution. thanks!

Answers

Problem 10
One foot is equal to 0.333 yards, so convert the feet to yards.
One inch is equal to 0.0278 yards.
(36 feet × 0.333 = 12) 36 feet = 12 yards
(24 feet × 0.333 = 8) 24 feet = 8 yards
(9 inches × 0.0278 = 0.25) 9 inches = 0.25 yards
Now, multiply it all together (L × W × H).
12 × 8 × 0.25 = 24 yards
Then multiply the number of cubic yards.
24 × 55= $1320
The answer is $1320

The reason this problem is so sneaky is that it has a lot of
different units in it, and you have to keep them all straight.

Volume of concrete for the patio = (length) x (width) x (height).

You know all of these dimensions, but be careful. Before
you multiply them, they must all be in the same units.

Length = 36 ft
Width = 24 ft
Height = 9 inches = 3/4 of a ft (0.75 ft).

NOW you can multiply to get the volume.

Volume = (36 ft) x (24 ft) x (0.75 ft) .

The result is the volume in ft³ (cubic feet).

Now you need to figure out how much this will cost, but you run into
another problem . . . you know how much each yd³ costs, but you
only have the volume in ft³. You have to change the ft³ into yd³ .

Here's the tool you need to do that: 1 yd³ = 27 ft³

The rest is just arithmetic. I know you can handle it from this point.

When dividing 878 by 31, a student finds a quotient of 28 with a remainder of 11. Check the students work, and use the check to find the error in the solution

Answers

There is an error in the student's work, the remainder should be 10

Further explanation

The division operation is one of the basic arithmetic operations

Common signs used are $\large{\boxed{:}}}$ or $\large{\boxed{\slash}}$

The division is written by placing the numerator above the denominator with a horizontal line between them or use a slash with the numerator's position and the denominator is parallel

The division is actually an iterative subtraction operation (as many as the number of divisors)

Division is the opposite of multiplying

The general form of division can be stated by:

$\large{\boxed{\bold{divident:divisor=quotient+remainder}}$

example:

7: 3 = 2 + 1

7 = dividend
3 = divisor
2 = quotient
1 = remainder

Division operation statement:

"7 divided by 3 equals 2 remainder 1"

The form of division can also be expressed in terms of fractions

In the example above, the form of mixed fractions :

$\displaystyle (7)/(3) =2(1)/(3)$

Mixed fractions consist of whole number and proper fractions

From the task

(see also the attached image)

When dividing 878 by 31, a student finds a quotient of 28 with a remainder of 11.

Division operation statement:

"878 divided by 31 equals 28 remainder 11

Arithmetic operations :

878 : 31 = 28 + 11

878 = dividend
31 = divisor
28 = quotient
11 = remainder

Because Division is the opposite of multiplying, so we check the solution with multiplying

divident - (divisor x quotient) = remainder

878 - (31 x 28) = 11

878 - 868 = 11

10 ≠ 11

So students make mistakes in subtraction operations,remainder should be 10
