**Answer:**

answer= 254

**Step-by-step explanation:**

Question

21$is 75% of what amount?

Solution 1

21 cents =75%

divide both sides by 3

7cents= 25%

multiply each side by 4

28=100%

Answer=28

divide both sides by 3

7cents= 25%

multiply each side by 4

28=100%

Answer=28

Question

Mara ran 3km north ad then 4km east. she will finish her run by running directly home. What is the total distance of her run

Solution 1

So we need to find the length of the hypotenuse of a right triangle with sides of 3 and 4, then add So we need to find the length of the hypotenuse of a right triangle with sides of 3 and 4, then add that distance to 3 and 4.

By the Pythagorean Theorme, the hypotenuse squared is equal to the sum of the sides squared...

d^2=3^2+4^2

d^2=9+16

d^2=25

d=âˆš25

d=5

So the total distance of her run is 5+4+3=12 km

By the Pythagorean Theorme, the hypotenuse squared is equal to the sum of the sides squared...

d^2=3^2+4^2

d^2=9+16

d^2=25

d=âˆš25

d=5

So the total distance of her run is 5+4+3=12 km

Solution 2

You can solve this with the Pythagorean theorem.

9+16=25, and the square root of 25 is 5. This is your answer.

9+16=25, and the square root of 25 is 5. This is your answer.

t=-1

24t=-24

t=-1

Question

What is the probability of spinning a 4 or an odd number?

Solution 1

Please explain further.

Question

Which of the following is the domain of the function G(F(x))? F(x) = x + 4, G(y) =
G(F(x)) =
A. All numbers less than or equal to 4
B. All numbers less than or equal to -4
C. All numbers greater than or equal to -4
D. All numbers greater than or equal to 4

Solution 1

1) G(F(x)) means

2) Mathematically that is:

G(F(x) = G (x + 4) =

3)Â The the domain is all the numbers for which the expression inside the root are not negative, i.e

That is the option C. all number greater than or equal to - 4.

Question

Josiah has 3 packs of toy animals. Each pack has the same number of animals. Josiah gives 6 animals to his sister stephanie. Then josiah has 9 animals left.how many animals were in each pack?

Solution 1

Let the number of animals in each pack be x.

Total number of animals will be 3x

after Josiah gave 6 animals to his sister the remaining animals were:

3x-6=9

thus sloving for x we have:

3x-6=9

add 6 on both sides

3x-6+6=9+6

3x=15

divide both sides by 3

(3x)/3=15/3

x=5

Answer:Â

There were 5 animals in each pack

Total number of animals will be 3x

after Josiah gave 6 animals to his sister the remaining animals were:

3x-6=9

thus sloving for x we have:

3x-6=9

add 6 on both sides

3x-6+6=9+6

3x=15

divide both sides by 3

(3x)/3=15/3

x=5

Answer:Â

There were 5 animals in each pack

Question

If 12 1/2% of a sum of money is $40 what is the total sum of money?

Solution 1

The total sum of **money **will be **$320.**

Let the *total sum of money* be represented by x.

Based on the information given, the **equation** to solve the question will be:

**12 1/2% Ã— x = 40**

0.125x = 40

**Divide by 0.125**

x = 40/0.125.

x = 320

Therefore, the total sum of** money **will be **$320.**

Read related link on:

Solution 2

12 1/2% = 12.5%

12.5% = $40

1% = 40 Ã· 12.5 = $3.20

100% = $3.20 x 100 = $320

**Answer: $320**

12.5% = $40

1% = 40 Ã· 12.5 = $3.20

100% = $3.20 x 100 = $320

Question

A ball is launched into the sky at 272 feet per second from the roof of a skyscraper 1,344 feet tall. The equation for the ballâ€™s height h at time t seconds is h = -16t2 + 272t + 1344. When will the ball strike the ground?

Solution 1

**Answer:**

** Time taken to reach the ball to the ground is 21 seconds.** Â Â Â Â Â Â Â Â Â

**Step-by-step explanation:**

**Given : **A ball is launched into the sky at 272 feet per second from the roof of a skyscraper 1,344 feet tall. The equation for the ballâ€™s height h at time t seconds is .

**To find :** When will the ball strike the ground?

**Solution : **

**The equation for the ball's height 'h' at time 't' is given by,**

**When the ball strike the ground the height of the ball became zero.**

**Substitute h=0 in the given equation,**

**Taking 16 common,**

**or **

**Solve by middle term split,**

**Reject t=-4 as time can never be negative.**

**Therefore, Time taken to reach the ball to the ground is 21 seconds.**

Solution 2

The answer is -16(t+4)(t-21)

Question

American cheese 0.45 to 4.26 what is the percent increase

Solution 1

For this case we have the following rule of three:

Â 0.45 ------> 100%

Â 4.26 ------> x

Â Clearing x we have:

Â x = (4.26 / 0.45) * (100)

Â x = 946.6666667%

Â Thus, the percentage of growth is:

Â 946.6666667 - 100 = 846.6666667

Â Rounding:

Â 846.7%

Â**Answer:**

Â**the percent increase is:**

Â**846.7%**

Â 0.45 ------> 100%

Â 4.26 ------> x

Â Clearing x we have:

Â x = (4.26 / 0.45) * (100)

Â x = 946.6666667%

Â Thus, the percentage of growth is:

Â 946.6666667 - 100 = 846.6666667

Â Rounding:

Â 846.7%
