Answer:

It will be worth $280.51.

Step-by-step explanation:

The compound interest formula is given by:

A = P(1 + \frac{r}{n})^{nt}

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per years and t is the time the money is invested or borrowed for, in years.

In this problem:

We want to find A, when P = 200, r = 0.07, n = 1, t = 5

A = P(1 + \frac{r}{n})^{nt}

A = 200*(1 + \frac{0.7}{1})^{1*5}

A = 280.51

It will be worth $280.51.

When Arjun makes hot cocoa, he adds 20\text{ mL}20 mL20, start text, space, m, L, end text of chocolate syrup for every 333 ounc
xxTIMURxx [149]

Answer:

Arjun's brother

Step-by-step explanation:

Given

Arjun = 20mL chocolate syrup to 3 ounce of hot water

Brother = 45mL chocolate syrup to 6 ounce of hot water

Required

Which is more chocolatey?

To get which is more chocolatey, we simply calculate the unit rate of chocolate per 1 ounce of hot water.

Unit\ Rate = \frac{Chocolate\ Syrup}{Hot\ Water}

For Arjun

Unit\ Rate = \frac{20}{3}

Unit\ Rate = 6.67mL/oz

For his brother

Unit\ Rate = \frac{45}{6}

Unit\ Rate = 7.5mL/oz

By comparison 7.5 > 6.67

Hence, Arjun brother's chocolate is more chocolatey.

The lengths of two sides of a triangle are given. describe the lengths possible for the third side.
vodomira [7]

Answer:

7m and 17m

Step-by-step explanation:

The length would be between 7m and 17m. This is because since the sum of two sides of a triangle must be greater than the third side. The sum of the third side and 6 must give us something greater than 12. This means the least the length can be is 7m. Since 6+12=18, the third side also has to be less than 18. This means the greatest the length can be is 17m.

C) P, Q, and R are prime numbers such that<br> 3 * P + 7 * Q + 15 * R = 102.<br> What is Q?
lana66690 [7]

Answer:

Q = 3

Step-by-step explanation:

3 * P + 7 * Q + 15 * R = 102

7Q = 102 - 3P - 15R

Q = (102 - 3P - 15R)/7

Try P = 2; R = 3

Q = 51/7 not an integer

Try P = 2; R = 5

Q = 21/7 = 3

Solution: P = 2; Q = 3; R = 5

Answer: Q = 3

Answer:

B. Jenny paid $322 for 23 T-shirts, which is a rate of $14 per T-shirt.
