The price of a four star meal, only $100 per couple decades ago, has since increased 200%. What is the current price?

1 answer:

6 0

Well if the price was $100 per couple and increased by 200% then it increased by 2 times the original price. So that means the price doubled so multiply. $100 by 2 which equals $200. So the current price is now $200.

in a school the ratio of boys to girls 6/5. what is the probability of choosing a girl from a class of 22?

kifflom [539]

the ratio 6/5 means for every 6 boys there are 5 girls.

Add the ratio: 6+5 = 11

Divide class total by 11: 22/11 = 2

Multiply each ratio number by 2 to find the number of boys and the number of girls:

6 x 2 = 12 boys

5 x 2 = 10 girls.

10 out of the 22 kids are girls.

The probability of picking a girl would be 10/22, which reduces to 5/11

Square root of 3.24 =

kvv77 [185]

Question says to find the square root of 3.24.

To find square root of decimal numbers, we can start by converting them into fraction so that decimal gets removed then find square root of numerator and denominator separately.

there are two digits after decimal in 3.24 so we can rewrite 3.24 as 324/100

Now let's find square root of the resulting fraction

$\sqrt{3.24}=\sqrt{\frac{324}{100}}= \frac{\sqrt{324}}{\sqrt{100}} = \frac{18}{10} = 1.8$

Hence final answer is 1.8.

Y=10 and 3x+2y=3

X=-3 is NOT a function because it has multiple y values for one x value.

Y equals ten is a horizontal line, and passes the vertical line test, as does the third equation
