Answer:

74 inches

Step-by-step explanation:

We can use Pythagorean Theorem, because this is a right triangle. We know it is a right triangle because of the little square in the corner indicating a right angle.

a^2+b^2=c^2

where a and b are the legs, and c is the hypotenuse.

We know that we are looking for c, so the other two sides must be the legs.

The other sides are 24 and 70. They are a and b.

24^2+70^2=c^2

Evaluate the exponents.

576+4900=c^2

Add

5,476=c^2

Take the square root of both sides. This is because c is being squared. Taking the square root will reverse that and leave c by itself.

74=c

So, the hypotenuse is 74 inches

Glynn's car has a 18 gallon gas tank. He travels 450 miles. What is the least miles per gallon this trip? Write and solve an ine

Ratling [72]

The least miles per gallon this trip is 25 miles per gallon

<h3>How to determine the least miles per gallon?</h3>

The given parameters are:

Distance = 450 miles

Tank size = 18 gallons

The least miles per gallon this trip is calculated as:

Miles per gallon = Distance/Tank size

This gives

Miles per gallon = 450/18

Evaluate the quotient

Miles per gallon =25

Represent as an inequality

x >= 25

Hence, the least miles per gallon this trip is 25 miles per gallon

in a farm there are 600 mango trees. the number of trees in each row is 10 less than twice the number of rows. does each row hav

iren [92.7K]

The area of the farm is the number of trees on it.

Each row of the farm does not have 50 trees

Let

$x \to$ number of rows

$y \to$ number of trees in each row

So, we have:

$y = 2x - 10$ --- twice less than the number of rows

The area of the farm is:

$Area = x \times y$

Where

$Area = 600$ --- the number of trees

So, we have:

$x \times y = 600$

Substitute $y = 2x - 10$

$x \times (2x - 10) = 600$

Substitute 50 for x

$50 \times (2 \times 50 - 10) = 600$

$50 \times (100 - 10) = 600$

$50 \times 90 = 600$

$4500 = 600$

The above equation is not true.

This means that, each row does not have 50 trees
