Ariel made cupcakes to sell. 2/3 of them were chocolate chip,25% of the reminder was strawberry and the rest were 90 vanilla cup

Anton [14]

Answer:

Let x be the total number of cupcakes.

Chocolate chips =

$\frac{2}{3} x$

Strawberry =

$\frac{1}{4} \times \frac{1}{3} \\ = \frac{1}{12} x$

Vanilla =

$x - \frac{2}{3} x - \frac{1}{12}x \\ = \frac{1}{3} x - \frac{1}{12} x \\ = \frac{1}{4} x$

given

$\frac{1}{4} x = 90$

$x = 90 \div \frac{1}{4} \\ = 90 \times 4 \\ = 360$

a)Number of Chocolate chip Cupcakes =

$\frac{2}{3} \times 360 \\ = 240$

b)Number of Strawberry cupcakes =

$\frac{1}{12} \times 360 \\ = 30$

I NEED HELP ASAP <br><br> APEX!!!

igor_vitrenko [27]

The series will be:

$4+16+64+.......+2^{50}$

Hence, Option A is the right answer

Step-by-step explanation:

The series can be fount out by putting the values of i in the expression written with the summation

The expression is:

$2^{2i}$

while i = 1 to 25

Putting i = 1

$2^{2(1)}\\= 2^2\\= 4$

Putting i = 2

$2^{2(2)}\\= 2^4\\= 16$

Putting i = 3

$2^{2(3)}\\= 2^6\\= 64$

....

Putting i = 25

$2^{2(25)}\\= 2^{50}$

The series will be:

$4+16+64+.......+2^{50}$

Hence, Option A is the right answer

Liza opens a new savings account. Assuming she deposits $15 every week, which equation represents the balance, y, of the savings

fiasKO [112]

B. “Y = 15x” would be your answer. Y is your end balance and x is the weeks. For example, if x is 3 weeks, your equation would be 45 = 15*3. In this case, y would be 45. Need anymore help?
