Answer: 19.20937

Step-by-step explanation:

a2=15

b2=12

c2=?

a2+b2=c2

15(15)+12(12)= c2

225+ 144=c2

Answer:

(x²+8x+16)π in²

Step-by-step explanation:

Since were not given the diagram of the circle. Let's assume the radius of inner circle is x+4

radius r = x+4

Area of the circle = πr²

Area of the circle = π(x+4)²

Area of the circle = π(x+4)(x+4)

Area of the circle =π(x²+4x+4x+16)

Area of the circle = π(x²+8x+16)

Area of the inner circle in terms of pi is (x²+8x+16)π in²

The formula for the volume of a sphere is 4⁄3πr³. For a cylinder, the formula is πr²h. A cone is ⅓ the volume of a cylinder, or 1⁄3πr²h.

Answer: 14 2/5 books per year

Step-by-step explanation:

From the question, we are informed that a middle school student reads 48 books in 31/3 years. The students reading rate in books per year will be calculated as:

= Total books read / Number of years

= 48 ÷ 3 1/3

= 48 ÷ 10/3

= 48 × 3/10

= 144/10

= 14 2/5 books per year

Answer:

p = -6.5

Step-by-step explanation:

-2(p-1) = 15

p-1 = -7.5

p = -6.5

Answer:

Let andre score be x points.

then Diego's score will be (x-9) points.

Noah's points=2(x-9) points

the equation is 2(x-9) = 10

dividing both sides by 2,

2(x-9)/2 =. 10/2

x-9= 5

adding 9 both sides,

x-9+9= 5+9

x=14.

Step-by-step explanation:

Answer:

Andre score 14 points

Step-by-step explanation:

noah = 2*diego

diego = andre - 9

given noah = 10

noah = 2*Diego

10 = 2*Diego

Diego = 5

diego = andre - 9

5 = andre - 9

andre = 9 + 5

Andre = 14

Answer: 1,179

Step-by-step explanation: because 1 kilogram = 1000 grams so the grams are more

Answer:

1,179 is more

Step-by-step explanation:

bcoz if we convert everything to kg then 1179 is 1.179kg

Answer:

25 lessons that cost $125

Step-by-step explanation:

If 8 lessons cost $96

then, 96/12 =8

therefore a lesson costs $8

If 25 lessons costs $125

then, 125/25= 5

therefore a lesson costs $5 which is cheaper.

Answer:

%11.76

Step-by-step explanation:

400/3400x100 = 11.76

Answer:

See explanation

Step-by-step explanation:

The first thing to do when given a data set is to ensure that the x-values are spaced in equal intervals.

The next is now to determine if the given y-values are increasing by the same amount(a common difference) or by the same ratio(a common ratio).

The data set is linear if the y-values increase by a common difference and the data set is exponential if the y-values increase by a ratio or factor.

Answer:

Which of the following steps did you include? Check all of the boxes that apply.

Make sure that the x-values are spaced apart in equal intervals.

Determine whether the y-values increase by the same amount or by the same ratio.

Decide that the data is linear because the y-values increase by a common difference.

Decide that the data is exponential because the y-values increase by a ratio or factor.

Answer:

The number of ways Kathy can paint her die is 52 ways

Step-by-step explanation:

The permutation and combination related question is answered as follows;

The number of faces in the six-sided die = 6

The number of colors available for painting the six-sided die = 2 colors

Therefore, we have, the total number of ways Kathy can paint her die, 'n', given as follows;

n = ₆P₂ + 2₄P₄ + 2₄P₃ + ₄P₂

Where;

₆P₂ = The number of ways of arranging 2 objects in 6 spaces = 30

₄P₄ = The number of ways of arranging 4 objects in 4 spaces = 1

₄P₃ = The number of ways of arranging 3 objects in 4 spaces = 4

₄P₂ = The number of ways of arranging 2 objects in 4 spaces = 12

∴ n = 30 + 2×1 + 2×4 + 12 = 52

The number of ways Kathy can paint her die, n = 52 ways.

Answer:

35 minutes

Step-by-step explanation:

Given that:

Trista:

Average word type per hour = 2400 words /hr

For Trista to type her 1400 word research paper ;

It will take 'h' hour

If

2400 words = 1 hour

1400 words = h

Cross multiply :

2400h = 1400

h = 1400 / 2400

h = 0.5833333 hr

To minutes, it will take :

0.5833333 * 60 = 35 minutes

Hence, it will take Trista 35 minutes or 0.5833333 to type her 1400 words research paper.
