The value of X is 5 because the dimensions of the first triangle is x=5 and 15 so therefore the second triangle has to have the same dimensions according to X so that would be 15 and 6(X)=30. As a result, X=5

the assumption here is that both triangles are similar, if that's so, then we can use proportions to get the sides.

Find the volume of a pyramid with a square base, where the perimeter of the base is 18.1 ft and the height of the pyramid is 28.1 ft. Round your answer to the nearest tenth of a cubic foot.

**Answer:**

191.8

**Step-by-step explanation:**

Hope this helps!

**Step-by-step explanation:**

the volume of a pyramid is

base area × height / 3

the base area here is a square.

we know its perimeter : 18.1 ft, which is 4 times the side length.

so, one side of the square is :

18.1/4 = 4.525 ft

the area of the square is side² = 4.525² = 20.475625 ft²

we also know the height of the pyramid, so the volume is :

Vp = 20.475625 × 28.1 / 3 = 191.7883542 ft³

the rounded volume of the pyramid is 191.8 ft³

Holly and Jimmy went shopping. For every $2

that Holly spent, Jimmy spent $5. If together

they spent $35, how much did Jimmy spend?

You can write the amount that they spent individually in a ratio where:

Holly : Jimmy

2 : 5

The total of this ratio would be 2+5 = $7.

To find the scale factor multiplier for the base ratio of 2:5:

35/7 = 5

Multiply both sides of the ratio by 5.

Holly : Jimmy

2 x5 : 5 x5

10 : 25

You can see that the total of this ratio is now $35, where Jimmy spent $25.

Holly : Jimmy

2 : 5

The total of this ratio would be 2+5 = $7.

To find the scale factor multiplier for the base ratio of 2:5:

35/7 = 5

Multiply both sides of the ratio by 5.

Holly : Jimmy

2 x5 : 5 x5

10 : 25

You can see that the total of this ratio is now $35, where Jimmy spent $25.

if you want it a a whole number, it would be for every 34$ 85 bucks for jimmy .

The **content **of the **mixture**, which are the **colour**, **developer**, and

**conditioner**, are in a fixed proportion to each other.

**Reasons**:

The **table **of the **amount **of each **product **used in the mixture are;

[tex]\begin{tabular}{|c|c|c|c|}Product&Colour&Developer&Conditioner\\Amount&30 ml&60 ml&60 ml\end{array}\right][/tex]

The number of **appointment **per month = **50**

The **quantities **used **per month **have a proportional relationship

Quantity used a month are;

Colour = 30 ml × 50 = **1,500 ml**

Developer = 60 ml = × 50 = **3,000 ml**

Conditioner = 60 ml × 50 = **3,000 ml**

Quantity available are;

Colour = **3.5 liters**

Developer = **0.5 liters**

Conditioner = **2.2 liters**

The quantity needed = **Quantity used - Quantity available**

Therefore;

Quantity needed are;

Colour = 1,500 ml - 3,500 ml = **-2,000 ml**

Developer = 3,000 ml - 500 ml = **2,500 ml**

Conditioner = 3,000 ml = 2,200 ml =** 800 ml**

Therefore, **Poppy **has enough **colour **but she **needs 2,500 ml **of developer and** 800 ml **conditioner

Therefore, she should order;

3,000 ml = **3 liters of developer**

1,000 ml =** 1 liter of conditioner**

Therefore;

Poppy is incorrect, she should order 3 liters of developer and 1 liter of conditioner.

Police response time to an emergency call is the difference between the time the call is first received by the dispatcher and the time a patrol car radios that it has arrived at the scene. Over a long period of time, it has been determined that the police response time has a normal distribution with a mean of 6.4 minutes and a standard deviation of 1.7 minutes. For a randomly received emergency call, find the following probabilities.

a) between 5 and 10 min.

b) less than 5 min.

c) more than 10 min.

The** probability **that a randomly received emergency call is between** 5 and 10 min** is **77.97%**.

Z score is used to** determine **by how man**y standard deviations** th**e raw score** is above or below the mean. It is given by:

**z = (x - μ) / σ**

Where μ is the mean, σ is the standard deviation and x is the raw score.

Given that μ = 6.4, σ = 1.7

For x = 5:

**z = (5 - 6.4) / 1.7 = -0.83**

For x = 10:

z = (10 - 6.4) / 1.7 = **2.12**

a) P(5 < x < 10) = P(-0.83 < z < 2.12) = P(z < 2.12) - P(z < -0.83) = 0.9830 - 0.2033 = **0.7797**

1. Tracy's is having a 25% off sale. Dana wants to buy a coat that has

an original price of $83. What is the sale price?

**Answer:20.75 after sale**

**Step-by-step explanation:**

25/100 of 83 is 2075

2075/100 = 20.75

After a discount of 25%, the sale price of a game system is $149.25. what is the original price?

**Answer:111.94**

**Step-by-step explanation:**

**'Percent (%)' means 'out of one hundred':**

**p% = p 'out of one hundred',**

**p% is read p 'percent',**

**p% = p/100 = p ÷ 100.**

**25% = 25/100 = 25 ÷ 100 = 0.25.**

**100% = 100/100 = 100 ÷ 100 = 1.**

**New value =**

**149.25 - Percentage decrease =**

**149.25 - (25% × 149.25) =**

**149.25 - 25% × 149.25 =**

**(1 - 25%) × 149.25 =**

**(100% - 25%) × 149.25 =**

**75% × 149.25 =**

Answer:

The solution of the system is (6, 9).

Step-by-step explanation:

Solve one of the variables and substitute the answer for the other variable.

Select one of the problems and solve for x.

3x+y=27

Subtract y from both sides.

3x+-y=27

Divide both sides by three.

x=1/3(-y + 27)

Multiply 1/3 by -y + 27.

x = -1/3y + 9

Replace -y/3 + 9 for x in the other problem 3x-2y=0.

3(-1/3y + 9) - 2y = 0

Multiply 3 by -y/3 + 9.

−y+27−2y=0

Add -y to -2y.

−3y+27=0

Subtract 27 from both sides of the problem.

−3y=−27

Divide both sides by −3.

y=9

Replace 9 for y in x=−1/3y+9.

x=−1/3*9+9

Multiply −1/3 times 9.

x=-3+9

Add 9 to -3.

x = 6.

x = 6, y = 9.

Halloween is the one day each year when its OK to play tricks on others and get loads of sweet treats. People in the United States and in other countries celebrate Halloween by dressing in costumes, attending parties, and going trick-or-treating.Halloween is celebrated on October 31. This is the day before the religious holiday All Saints Day, which was once known as All Hallows. October 31 was often called All Hallows Eve. Over time, this name was shortened to Halloween. All Saints Day marks the memory of saints and other people who have died. At first, the celebration consisted of a prayer service dedicated to the dead. The prayer service was followed by a small offering at the dead persons tomb or grave. People traditionally spent the day praying and mourning for the souls of those who had died.However, Halloween is celebrated differently today. Dressed like witches, wizards, and goblins, children go from house to house trick-or-treating for candy. They also participate in Halloween activities such as carving pumpkins, bobbing for apples, and watching scary movies.Halloween celebrations arent limited to kids. Many adults celebrate by dressing in costume to attend Halloween parties. Others walk through haunted houses and other scary places.Halloween is more than a one-day holiday. The celebration can continue throughout the month of October. Its a holiday that allows people of all ages to dress up, go to haunted places, and play pranks. Its not serious or sad, unlike the traditional celebrations. For this reason, most people enjoy Halloween celebrations more these days.For this reason, most people enjoy Halloweencelebrations more these days.People in the United States and in othercountries celebrate Halloween by dressingin costumes, attending parties, and goingtrick-or-treating.Who doesnt like playing pranks on peopleor eating candy?hookarrowRightconclusionarrowRightthesis statementarrowRight
