To calculate the volume of each can, we can use the formula for the volume of a cylinder:

Volume =πr²h

Using the given values, we can calculate the volume for each option:

Option 1:

Radius = 2.5 inches

Height = 6 inches

Volume = 3.14 x (2.5²) x 6 = 117 in³

Option 2:

Radius = 1.5 inches

Height = 3 inches

Volume = 3.14 x 1.5² x 3 = 21.195 in³

Option 3:

Radius = 2 inches

Height = 2.25 inches

Volume = 3.14 x 2² x 2.25 = 28.26 in³

Option 4:

Radius = 1.5 inches

Height = 6 inches

Volume = 3.14 x 1.5² x 6 =42.39 in³

Option 5:

Radius = 2 inches

Height = 4 inches

Volume = 3.14 x 2² x 4 = 50.24 in³

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

6

Step-by-step explanation:

18-2.5+7 there s your helllppppppppppp

Part A: The original triangle has a base of 18 feet and a height of 7 feet. To create the 2:5 scaled version of the deck, we can simply multiply the base and height of the original triangle by the scale factor of 2/5.

New base = 18 x 2/5 = 7.2 feet
New height = 7 x 2/5 = 2.8 feet

Therefore, the dimensions of the new deck are 7.2 feet for the base and 2.8 feet for the height.

Part B: To find the area of the original deck, we can use the formula for the area of a triangle, which is:

Area = (1/2) x base x height

Area = (1/2) x 18 x 7 = 63 square feet

To find the area of the new deck, we can use the same formula and plug in the new dimensions:

Area = (1/2) x 7.2 x 2.8 = 11.88 square feet

Therefore, the area of the original deck is 63 square feet and the area of the new deck is 11.88 square feet.

Part C: The ratio of the areas is:

63/11.88 = 5.303

The scale factor is:

2/5 = 0.4

To compare the ratio of the areas to the scale factor, we can divide the ratio of the areas by the scale factor:

5.303/0.4 = 13.2575

Therefore, the ratio of the areas is 13.2575 times the scale factor.

Answer: 4/5 = 180/b; b = 225 boys

Answer:

Given that there are 4 boys for every 5 girls, we can set up the following proportion:

4/5 = x/180

where x is the number of boys.

To solve for x, we can cross-multiply:

5x = 4 * 180

5x = 720

x = 144

Therefore, there are 144 boys.

Set up and solve a system of equations to solve the problem.

A jar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of the coins is $1.50. How many nickels and how many dimes are in the jar?

The jar contains ___ nickels and ___ dimes.

Answers

Answer:

The jar contains 10 nickels and 10 dimes. Another answer is that the jar contains 4 nickels and 13 dimes.

Step-by-step explanation:

1 nickels = 5 cents

1 dime = 10 cents

1st answer

10 nickels = $0.50

10 dimes = $1.00

So 10 nickels + 10 dimes = $1.50

2nd answer

13 dimes = $1.30  

4 nickels = $0.20

So 13 dimes + 4 nickels = $1.50

10 nickels and 10 dimes

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)

Answers

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Triangle WYT is an isosceles if angle Y is equal to 156 then what are the other two angles? brainliest and five⭐ for the first who answers! 50 POINTS ON THIS QUESTION!

Answers

Answer: 12

Step-by-step explanation:

since it’s isosceles, the bottom two angles are equal so just subtract 156 from 180 and then divide that by 2.

Whenever you see an isosceles triangle, you should know that the bottom two angles are the half of the top angle subtracted from 180. So, 180-156=24 —> 24/2= 12°
