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:

There were 5 animals in each pack

add 6 on both sides

3x-6+6=9+6

3x=15

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% × x = 40**

0.125x = 40

**Divide by 0.125**

x = 40/0.125.

x = 320

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

Solution 2

12 1/2% = 12.5%

12.5% = $40

1% = 40 ÷ 12.5 = $3.20

100% = $3.20 x 100 = $320

**Answer: $320**

12.5% = $40

1% = 40 ÷ 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 ball’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.**

**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 ball’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:

0.45 ------> 100%

4.26 ------> x

Clearing x we have:

x = (4.26 / 0.45) * (100)

x = 946.6666667%

Thus, the percentage of growth is:

946.6666667 - 100 = 846.6666667

Rounding:

846.7%

**Answer:**

**the percent increase is:**

**846.7%**

0.45 ------> 100%

4.26 ------> x

Clearing x we have:

x = (4.26 / 0.45) * (100)

x = 946.6666667%

Thus, the percentage of growth is:

946.6666667 - 100 = 846.6666667

Rounding:

846.7%

Question

The average score on a standardized test is 750 points with a standard deviation of 50 points. What is the probability that a student scored more than 850 on the standardized test ?

Solution 1

The probability that student scored more than 850 we shall proceed as follows:

z=(x-μ)/σ

where:

x=850

μ=750

σ=50

thus

z=(850-750)/50

z=2

thus

P(x>850)=1-P(x<850)=1-P(z<2)=1-0.9772=0.0228

Answer: P(x>850)=0.0228

z=(x-μ)/σ

where:

x=850

μ=750

σ=50

thus

z=(850-750)/50

z=2

thus

P(x>850)=1-P(x<850)=1-P(z<2)=1-0.9772=0.0228

Answer: P(x>850)=0.0228

Question

A rectangle has a width of 8 centimeters and an area of 160 square centimeters a similar rectangle has an area of 250 square centimeters. What are the dimensions of the larger rectangle?

Solution 1

I'm a bit confused and there is not a lot of information given to this.

From what I know, the dimensions of the larger rectangle can be found from length x width = 250 square centimetres.

Any multiplication problem that equals 250 could work out for length x width.

Question

Which point best approximates the root of 45

Solution 1

To solve for √45 we shall proceed as follows:

We rewrite 45 as 3²×5

thus

√45=√(3²×5)

pulling terms out from under the radical we obtain

3√5

thus the exact answer form is:

3√5

or the decimal form is:

6.70820393

We rewrite 45 as 3²×5

thus

√45=√(3²×5)

pulling terms out from under the radical we obtain

3√5

thus the exact answer form is:

3√5

or the decimal form is:

6.70820393
