A basketball shaped like a sphere has a diameter of 8 inches. Which measurement is
to the volume of the basketball in cubic inches?

Answers

Answer:

268

Step-by-step explanation:

The volume formula for a sphere is: V= [tex]\frac{4}{3}\pi r^{3}[/tex]

We also know that [tex]\pi[/tex] is approximately 3.14.

You have to know these in order to solve the question..

Since we also know the diameter is 8 we can also find the radius (r) ,which is half of the diamater so 4.

Now all we need to do it plug in the numbers.

V= [tex]\frac{4}{3}[/tex](3.14)[tex]4^{3}[/tex]

Now solve for the equation.

V=267.94...

So rounded that is 268.

If nkf ~ lzf, find nf, please help me with this it’s due tmr!!!!

Answers

Answer:

NF = 25

Step-by-step explanation:

Since ∆NKF ~ ∆LZF, the ratio of their corresponding side lengths would also be the same.

This means that:

KF/ZF = NF/LF

KF = x + 3

ZF = 4

NF = 15 + x + 3 = x + 18

LF = x + 3

Plug in the values into the equation

(x + 3)/4 = (x + 18)/(x + 3)

Cross multiply

(x + 3)(x + 3) = (x + 18)(4)

x² + 3x + 3x + 9 = 4x + 72

x² + 6x + 9 = 4x + 72

x² + 6x + 9 - 4x - 72 = 0

x² + 2x - 63 = 0

Factorize to find x

x² + 9x - 7x - 63 = 0

x(x + 9) -7(x + 9) = 0

(x + 9)(x - 7) = 0

x + 9 = 0 or x - 7 = 0

x = -9 or x = 7

We'd use the positive value of x, which is 7.

Therefore, x = 7.

✅NF = 15 + (x + 3)

Plug in the value of x

NF = 15 + (7 + 3) = 15 + 10

NF = 25

First open the parentheses by applying the distributive property.

To do this, multiply each term you have inside (-3x⅔ + 5x + 7) by -1.

Thus, you would have the following:

Answer:

  not similar

Step-by-step explanation:

For the triangles to be similar, at least two angles must match. Here, there is an 81° angle in both triangles. This means the sum of the remaining two angles must be ...

  180° -81° = 99°

If the missing angle in either triangle matched the other given angle in the opposite triangle, the sum of those would be 60° + 40° = 100°, not 99°. This triangle pair does not have two matching angles, so the triangles are not similar.

ABC angles: 60°, 81°, 39°

FED angles: 59°, 81°, 40°

The set for a school play needs a replica of a historic building painted on a backdrop that is 20 feet long and 16 feet high. The actual building measures 320 feet long by 256 feet high. A stage crewmember writes (x, y) arrow right ( 1/20 x, 1/20y) to represent the dilation. Is the crewmember's calculation correct if the painted replica is to cover the entire backdrop? Complete the explanation.

Answers

Answer:

Stage crewmember's calculation is incorrect

Correct = 1/16x 1/16y

Step-by-step explanation:

Given that:

Dimension of backdrop : 20 feets long ; 16 feets high

Actual dimension of building : 320 feets long ; 256 feets high

The correct scale factor can be obtained thus :

Ratio of backdrop dimension to the actual dimension of building

Length : 20 / 320 = 1 /16

Height : 16 / 256 = 1/16

Hence, stage crewmember's calculation of (1/20x ; 1/20y) is incorrect.

у = х + 3
у =-2x-3

Answers

Answer:

x = - 2, y = 1

Step-by-step explanation:

Comparing both the equations,

→ y = y → x + 3 = - 2x - 3

=> x + 3 = - 2x - 3

=> x + 2x = - 3 - 3

=> 3x = - 6

=> x = - 6/3 = - 2

Substitute the value of x in any of these:

=> y = x + 3 = - 2 + 3 = 1

Answer:

Step-by-step explanation:

If a solution exists for the system of equations y=y so we can say

x+3=-2x-3 Add 2x to each side

3x+3=-3 Subtract 3 from each side

3x=-6. Divide each side by 3

x=-2, since y=x+3

y=-2+3

y=1

So the solution to the system of equations is the point (x,y)=(-2,1)

An angle measures 46° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

67 degree

113 degree

Step-by-step explanation:

Supplementary angles are angles that measure up to 180 degrees. For example, if one angle measures 60 degree, the other angle would measure (180 - 60) 120 degrees

Let x represent the smaller angle

The bigger angle = x + 46

We know that both the smaller and the bigger angle would add up to 180, thus this equation can be written :

x + 46 + x = 180

2x + 46 = 180

Collect like terms

2x = 180 - 46

2x = 134

Divide both sides by 2

x = 67 degrees

the bigger angle = 67 + 46 = 113 degree

Answer:

31.5

Step-by-step explanation:

First we want to find what side NP is equal to. To do that we divide 4 by 12

12/4=3 so side mp=3

next we want to find the scale factor of the rectangles. to do that we divide 4 from 9

9/4=2.25

next we want to find what side st is equal too

to do that we multiply 3 by 2.25

3x2.25=6.75

finally we want to find the perimeter and to do that we do 2(6.75)+2(9)

2(6.75)+2(9)=31.5 so the perimeter of rectangle RSTU is 31.5

the number of squirrels in a park at the end of the month

Answers

Using the given recursive function, we have that:

a) There will be 132 squirrels in the park at the end of August.

b) As time goes by, the number of squirrels in the park will increase.

What is the recursive function for this problem?


The recursive function for this problem models the number of squirrels in the park at the end of month n+1, considering the amount present at the end of month n, as follows:

[tex]S_{n+1} = 1.6S_n - 30[/tex]

For this problem, we have that at the amount at the end of May is of 70, hence:

[tex]S_{5} = 70[/tex]

Hence, we find the amounts at the end of June, July and August, as follows:

[tex]S_6 = 1.6(70) - 30 = 82[/tex].[tex]S_7 = 1.6(82) - 30 = 101[/tex].[tex]S_8 = 1.6(101) - 30 = 132[/tex].

Hence:

a) There will be 132 squirrels in the park at the end of August.

b) As time goes by, the number of squirrels in the park will increase.

Even old Mahailey was enlightened by their words of wisdom.Mrs. Wheeler said she would never forget the night Ernest arrived from the Old Country. His brother, Joe Havel, had gone to Frankfort to meet him, and was to stop on the way home and leave some groceries for the Wheelers. The train from the east was late; it was ten o'clock that night when Mrs. Wheeler, waiting in the kitchen, heard Havel's wagon rumble across the little bridge over Lovely Creek. She opened the outside door, and presently Joe came in with a bucket of salt fish in one hand and a sack of flour on his shoulder. While he took the fish down to the cellar for her, another figure appeared in the doorway; a young boy, short, stooped, with a flat cap on his head and a great oilcloth valise, such as pedlars carry, strapped to his back. He had fallen asleep in the wagon, and on waking and finding his brother gone, he had supposed they were at home and scrambled for his pack. He stood in the doorway, blinking his eyes at the light, looking astonished but eager to do whatever was required of him. What if one of her own boys, Mrs. Wheeler thought. . . . She went up to him and put her arm around him, laughing a little and saying in her quiet voice, just as if he could understand her, "Why, you're only a little boy after all, aren't you?"Ernest said afterwards that it was his first welcome to this country, though he had travelled so far, and had been pushed and hauled and shouted at for so many days, he had lost count of them.
