Answer:

<h2>A. 33 1/3%</h2>

Step-by-step explanation:

Givens

9 chicken meals for $5 each.

15 burger meals for $6 each.

First of all, notice that the total money spent is $135.

\$5(9)+ \$ 6(15)=45+90=\$135

But chicken meals only was: \$5(9)=\$45

Then, we divide and multiply by 100 to find the percentage

\frac{45}{135} \times 100 = 33.33 \%.

Therefore, chicken meals represent a 33 1/3% of total expenses.

How do I solve for c and d
tankabanditka [31]
For c using proportionality of corresponding sides you can writing 

(3c+4)       9
--------- = -------
    20         15

(3c+4)       3
---------- = ------    cross multiple 
    20          5

5(3c+4) = 20*3   divide both sides by 5

3c+4=4*3

3c+4=12

3c = 8

c = 8/3

for d you can writing 

(2d-3)       9
--------- = ------
   12          15

(2d-3)       3
--------- = -------   cross multiple 
   12          5

5(2d-3) = 12*3

10d -15 = 36

10d = 51

d = 51/10

d = 5,1

Answer:

  about 130 hp

Step-by-step explanation:

The displacement is smaller by a factor of 220/390, so we expect the horsepower to be smaller than 230 hp by the same factor:

  (220/390)(230 hp) ≈ 129.74 hp ≈ 130 hp

There are four numbers of 3-coin combinations if we can choose from nickels, dimes, quarters, and half-dollars.

<h3>How to solve probability combinations?</h3>

The coins to select from are nickels, dimes, quarters, and half-dollars;

Thus;

Coins (n) = 4

The number of coin to select is:

Coin (r) = 3

The coin combination is then calculated using:

Combination = ⁴C₃

Apply the combination formula, we have;

Combination = 4

Thus, there are four number 3-coin combinations if we can choose from nickels, dimes, quarters, and half-dollars.

What is 80% as a simplified fraction
Nataly_w [17]

Answer: 4/5

Step-by-step explanation:

Step 1: Put the percent over 100

- 80/100

Simplify it by dividing both the numerator and denominator by a common factor, aka 10

- 80/10 - 8

100/10 - 10

- 8/10

Simplify it again by dividing both the numerator and denominator by a second common factor, aka 2

= 8/2 - 4

10/2 - 5

- 4/5

Cannot be simplified any further.
