Answer:

1) 28.4 miles per gallon

2) 34 miles per gallon

3) the red car

Step-by-step explanation:

Blue car:

Travels 35 1/2 miles on 1 1/4 gallons of gasoline

Red car:

Travels 27 1/5 miles on 4/5 gallons of gasoline

We want to know the unit rate for miles per hour, and to do it we have to divide the miles they travel by the gallons each car uses:

Blue car:

(35 1/2) / (1 1/4) = 28.4 miles per gallon

Red car:

(27 1/5) / (4/5) = 34 miles per gallon

The red car travels greater distance with 1 gallon of gasoline {and thats about it!}

Which set of lengths are not the side lengths of a right triangle? (A-28, 45, 53) (B-13, 84, 85) (C-36, 77, 85) (D-16, 61, 65) [
nikklg [1K]
Side lengths 16, 61, and 65 are not part of a right triangle.

A right triangle's sides should follow this formula, C being the largest number:

a^{2} + b ^{2} = c^{2}

16^{2} = 256

61^{2} = 3721

65^{2} = 4225

256 + 3721 = 3977

3977  \neq 4225

A store has 5 travel guide books and 9 fictions on the shelves. If two customers bought a book, find the probability that one of
Jlenok [28]

Answer:

Probability = \frac{45}{98}

Step-by-step explanation:

Given

Represent travel guide with T and Fictions with F

T = 5

F = 9

Required

Determine the probability that one of both was selected

This implies that (1 travel guide and 1 fiction) or (1 fiction and 1 travel guide)

The probability is is calculated as thus:

Probability = P(T\ n\ F)\ or\ P(F\ n\ T)

In probability, the above formula can be translated to

Probability = P(T) *P(F)\ +\ P(F) *P(T)

Probability = \frac{n(T)}{Total} *\frac{n(F)}{Total}\ +\ \frac{n(F)}{Total} *\frac{n(T)}{Total}

Probability = \frac{5}{5 + 9} *\frac{9}{5 + 9} +\frac{9}{5 + 9} *\frac{5}{5 + 9}

Probability = \frac{5}{14} *\frac{9}{14} +\frac{9}{14} *\frac{5}{14}

Probability = \frac{45}{196} +\frac{45}{196}

Probability = \frac{90}{196}

Probability = \frac{45}{98}
