Jesse sold cupcakes and cookies yesterday. Each cupcake sold for $1.50 and each cookie sold for $0.25. At the end of the day, Je

Answer: 19 cupcakes and 37 cookies were sold.

Step-by-step explanation:

Let x represent the number of cupcakes that Jesse sold yesterday.

Let y represent the number of cookies that Jesse sold yesterday.

If he sold 56 cupcakes and cookies combined, it means that

x + y = 56

Each cupcake sold for $1.50 and each cookie sold for $0.25. At the end of the day, Jesse had sold $37.75 worth of cookies and cupcakes. This means that

1.5x + 0.25y = 37.75 - - - - - - - - - - -1

Substituting x = 56 - y into equation 1, it becomes

1.5(56 - y) + 0.25y = 37.75

84 - 1.5y + 0.25y = 37.75

- 1.5y + 0.25y = 37.75 - 84

- 1.25y = - 46.25

y = - 46.25/ - 1.25

y = 37

x = 56 - y = 56 - 37

x = 19

What is half of the product of 8 1/7 and 7 4/5

UNO [17]

First we must convert these mixed numbers to improper fractions:

$8\frac{1}{7}=\frac{57}{7}$

$7\frac{4}{5}=\frac{39}{5}$

So then we need the product of these two numbers. That means to multiply:

$\frac{57}{7}* \frac{39}{5}= \frac{2,223}{35}$

But then we need the value of half of this product. So then let's multiply by one-half:

$\frac{2,223}{35} *\frac{1}{2} =\frac{2,223}{70}$

Then we can convert this from an improper fraction to a mixed number:

$\frac{2,223}{70} =31\frac{53}{70}$

And so this number is half of the product of the initial two numbers.

Answer:

Option (b) is correct.

$(2^\frac{1}{4} )^4=2^\frac{1}{4} \times 2^\frac{1}{4}\times 2^\frac{1}{4}\times 2^\frac{1}{4}=2^{(\frac{1}{4}+ \frac{1}{4}+ \frac{1}{4}+ \frac{1}{4} )}=2^{1}=2$
