Sharonda uses a blend of dark chocolate and milk chocolate to make the ice cream topping at her restaurant. She needs to buy 120
White raven [17]

Step-by-step explanation:

ATQ,

Let d be the number of kilograms of dark chocolate she buys and m be the number of kilograms of milk chocolate she buys.

She needs to buy 120 kg of chocolate in total for her next order, and her recipe calls for twice the amount of dark chocolate as milk chocolate.

So,

m = 2d .....(1)

m + d = 120 ...(2)

We can also solve the above equations,

Put m = 2d in equation (2)

2d + d = 120

3d=120

d = 40

Put d = 40 in equation (1)

m = 2(40)

m = 80

Hence, she will need 40 kg of dark chocolate and 80 kg of milk chocolate.

an item was sold at loss of 20%. had it been sold for rs3000 more then the profit would have been 10%. What is the cost price of
iVinArrow [24]

Answer:

10000

Step-by-step explanation:

Assumed that the cost price of the item is x.

It was sold at a loss of 20%:

therefore the price sold was 0.8x

If it was sold at a profit of 10%:

the price sold would have been 1.1x

Since the difference in price is 3000:

1.1x - 0.8x = 3000

0.3x = 3000

x = 10000

Does this set of ordered pairs represent a function? {(–2, 3), (–1, 3), (0, 2), (1, 4), (5, 5)} A. The relation is a function. E
Aleks04 [339]

The correct option regarding whether the relation is a function is:

B. The relation is a function. Each input value is paired with one output value.

<h3>When does a relation represent a function?</h3>

A relation represent a function if <u>each value of the input is paired with one value of the output</u>.

In this problem, when the input - output mappings are given by:

{(–2, 3), (–1, 3), (0, 2), (1, 4), (5, 5)}.

Which means that yes, each input value is paired with one output value, hence the relation is a function and option B is correct.

Juan is 1 1/4 feet shorter than Maria. Maria is 1/3 foot taller than Luis. If Luis is 62 inches tall, how tall are Maria and jua
Nataliya [291]

Answer:

Maria is 66" tall, Juan is 51" tall

Step-by-step explanation:

There are 12 inches to a foot.  

Luis is 62" tall

Maria is 1/3 of a foot taller than Luis,  1/3 of 12 is 4, (multiply 12 by 1/3)

 So Maria is 4 inches taller than Luis, making her 66" tall

Juan is 1 1/4 feet shorter than Maria,  that's one foot and 1/4 of a foot shorter,  1/4 of 12 is 3 (multiply 12 by 1/4)

  So Juan is one foot (12 inches) plus 3 more inches shorter than Maria,

    Juan is 15 inches shorter than Maria, making him 51" tall
