Let the number of cats be as x

Ratio = 3:5
3:5 = 21 : x
3/5 = 21/x
x= 21 * 5/3
x= 5* 7
= 35 cats..

X - the number of cats

The ratio of dogs to cats is 3:5, and there are 21 dogs.
$\frac{21}{x}=\frac{3}{5} \\
3x=21 \times 5 \\
x=7 \times 5 \\
x=35$

There are 35 cats in the pet store.

Your answer is $1.26
You can solve this problem with or without a calculator, and I don't know if you're allowed one or not so I'll show you both ways

Calculator:
The easiest way to find percentages of values on the calculator is to use the decimal multipliers, which are just the decimal value of the percentage. For example, 50% would be 0.5, 75% would be 0.75 etc. The decimal value of 15% is 0.15, so you would do 8.40 × 0.15 = 1.26

Non-Calculator:
This is a bit longer, but gives you the same answer. To solve without a calculator, you first divide 8.40 by 10 to find 10%, which is 0.84. Now you can divide that by 2 to find 5%, which would be 0.42, and then you add the two values (because 10% + 5% = 15%) to get 1.26

I hope this helps!

ser-zykov [4K]

Answer:

(a) $\frac{1}{17}$ (b) $\frac{1}{16}$

Step-by-step explanation:

GIVEN: Suppose that two cards are randomly selected from a standard $52$ card deck.

TO FIND: (a) What is the probability that the first card is a club and the second card is a club if the sampling is done without replacement? (b) What is the probability that the first card is a club and the second card is a club if the sampling is done with replacement.

SOLUTION:

(a)

Probability that first card is club $P(A)=\frac{\text{total club cards}}{\text{total cards}}$
