Answer:

90 minutes

Step-by-step explanation:

If Jim takes 30 minutes to write 10 sentences, we can write a proportion.

\frac{30}{10}=\frac{x}{30}

Cross multiply so we get 10x=900.

And simplify.

x=90

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.

Work must be shown for this problem! The figure shown below is a rectangle. Make sure to solve for x and BD. Give both answers b
AnnyKZ [126]

Answer:

x = 10 and BD = 74

Step-by-step explanation:

AE and CE are equal, so we can set those 2 values equal to each other to find x.

3x + 7 = 37

3x = 30

x = 10

BD will be equal to AE + CE because that is a property of the rectangle.

So AE + CE = 37 + 37 = 74.

BD = 74

Handy Dandy Grocery is having a sale this week. If you buy a 5−pound bag of apples for the regular price, you can get another ba
Elis [28]

Answer:

To get the discount for the 5 pound bag of apples, we must first note the following:

The original price of the apples, which in this case it is 2.99

Also we must note the sale price for the apples which is 1.59

to get the discount for apples we must then create an equation based on the above information,

Discount for A= original price -sale price

Discount for A=2.99-1.59

Discount for A=1.40

Part 1 Answer is 1.40 which is the discount for apples at Handy Dandy Grocery.

Part 2

To get the discount for oranges we follow the same steps.

Discount for R= Original price for R -sale price for R

Discount for R=3.99-2.59

Discount for R=1.40

conclusion, for both part one and part two we can derive a formula based on the apples and orange and say discount in both cases is arrived by the following:

D=Op-Sp. ( d= discount, Or= original price, Sp= sale price.)
