A bakery sold 210 vanilla cupcakes in a day, which was 42% of the total number of cupcakes sold that day. How many total cupcake

aleksandr82 [10.1K]

Answer:

if im wrong sorry

Step-by-step explanation:

ok if 210 is 42% then a other 210 vanilla Cupcakes will be another 42% so

210=42

42+42= 84%

210+210=420 Vc

420 Vc= 84%

you need 16% left to become 100% so what i did was 210 - 16% was 176.4 Vc.

so 420+ 176.4= 596.4

596.4 vanilla Cupcakes were sold in that day

Abby bought two slices of pizza and three bottles of water for $7.25 Cameron bought four slices of pizza and one bottle of water

grin007 [14]

The solution is price of 1 slice of pizza is $ 1.75 and price of 1 bottle of water is $ 1.25

Solution:

Let "p" be the price of 1 slice of pizza

Let "b" be the price of 1 bottle of water

Given that Abby bought two slices of pizza and three bottles of water for $7.25

So we can frame a equation as:

two slices of pizza x price of 1 slice of pizza + three bottles of water x price of 1 bottle of water = $ 7.25

$2 \times p + 3 \times b = 7.25$

2p + 3b = 7.25 ------- eqn 1

Cameron bought four slices of pizza and one bottle of water for $8.25

So we can frame a equation as:

four slices of pizza x price of 1 slice of pizza + one bottles of water x price of 1 bottle of water = $ 8.25

$4 \times p + 1 \times b = 8.25$

4p + 1b = 8.25 ----- eqn 2

Let us solve eqn 1 and eqn 2 to find values of "p" and "b"

Multiply eqn 1 by 2

4p + 6b = 14.5 ----- eqn 3

Subtract eqn 2 from eqn 3

4p + 6b = 14.5

4p + 1b = 8.25

( - ) ------------------

5b = 6.25

b = 1.25

Substitute b = 1.25 in eqn 1

2p + 3b = 7.25

2p + 3(1.25) = 7.25

2p + 3.75 = 7.25

2p = 3.5

p = 1.75

Summarizing the results:

price of 1 slice of pizza = $ 1.75

price of 1 bottle of water = $ 1.25

Which of the following forms associated with exponents multiplies the base number by itself as many times as needed?

USPshnik [31]

Answer:

The correct answer is B. Exponential form.

Step-by-step explanation:

The exponential form was developed to express repeated multiplications and to make it easier to write long numbers. The exponential notation has two parts. The base, as the name says, is the number below. The other part of the notation is a small number written on the superscript to the right of the base, called an exponent. We will use an example to learn about the exponential form or notation.

2³

In this example the base is 2. This means that 2 is a factor, and that it will be multiplied by itself a certain number of times. The precise number of times is given by the exponent, the number in the superscript. In this case, the exponent is 3, which means that base 2 will be used as a factor 3 times. So 2³ means 2 • 2 • 2 and the result is 8.
