You already have the rates, what you need to find out now is the unit rates. To do this, you simply take first number (eg.420) to divide by the second number (eg. 7).
a.60 miles per hour
b. 12 customers per day
c. 2.5 meters in 1 pound
d. $1.592 for 1 ound

A. 420 miles in 7 hours = 420miles/7hours = 60 miles/hour

b. 360 customers in 30 days = 360 customers/30 days = 12 customers / day.

c. 40 meters in 16 pounds = 40 meters / 16 pounds = 2.5 meters / pound

d. $7.96 for 5 pounds = $7.96 / 5 pounds = $ 1.592 / pound

The denominator of a fraction is 10 more than its numerator.

Dennis_Churaev [7]

The right answer is Option C : 5

Step-by-step explanation:

Let,

The numerator of fraction = x

The denominator of a fraction is 10 more than its numerator.

$\frac{x}{x+10}$

When 1/3 is added to this fraction,

$\frac{x}{x+10}+\frac{1}{3}$

the resulting fraction’s denominator is three times the denominator of the original fraction its numerator is 15 less than its denominator

$\frac{3(x+10)-15}{3(x+10)}$

Therefore, it becomes

$\frac{x}{x+10}+\frac{1}{3} = \frac{3(x+10)-15}{3(x+10)}$

Taking LCM on left side

$\frac{3x+(x+10)}{3(x+10)}=\frac{(3x+30)-15}{3(x+10)}\\\\\frac{3x+x+10}{3(x+10)}=\frac{3x+30-15}{x(x+10)}\\\\\frac{4x+10}{3(x+10)}=\frac{3x+15}{3(x+10)}$

Multiplying both sides by 3(x+10)

$3(x+10)*\frac{4x+10}{3(x+10)}=\frac{3x+15}{3(x+10)}*3(x+10)\\4x+10=3x+15\\4x-3x=15-10\\x=5$

The numerator of original fraction is 5.

The right answer is Option C : 5

Step-by-step explanation:

M=(x1+x2 / 2 , y1+y2 / 2)

M=(-2+4 / 2 , 4+ -2 / 2)

M=(2 / 2 , 2 / 2)

M=(1,1)

What is the probability of not rolling a number larger than 4 with a fair die?

Fiesta28 [93]

Find the probability of rolling a number bigger than 4 and subtract that by 100%;

P(5)= 1/6 <-- 6 possible outcomes, 1, 2, 3, 4, 5 or 6
P(6)= 1/6

You could have rolled a 5 or 6. When the word or is used, the probabilities are added together, when and is used, they are multiplied.

(1/6)+(1/6)=2/6

1-P(5)+P(6)
=1-(2/6)
=(6/6)-(2/6)
=4/6

Therefore the probability of not rolling a number larger than 4 is 4/6 or 2/3.

Hope I helped :)
