Answer:

  120 units²

Step-by-step explanation:

The area can be found using the formula for the area of a triangle:

  A = 1/2bh

Since the sides of length 10 and 24 are at right angles, either can be considered to be the base and the other the height. Then the area is ...

ser-zykov [4K]

Question :

5m^2 - 29m + 20

Steps:

What can u factor to get 20?

you can make 5 and 4 to make 20 so,..

1. Break it into groups

(5m^2 - 4m) + (-25m + 20)

*Factor out m from (5m^2 - 4m) : m(5m - 4)

*Factor out -5 from (-25m + 20) : -5(5m - 4)

2. Then, you can factor out the common term : (5m - 4) because they both have it. And then u would move the m by the -5 so,...

= (5m - 4)(m - 5) <======= <em>Answer</em>

Sveta_85 [38]

Josh's monthly fuel expenses are $1,050.

<h3><u>Prices</u></h3>

Given that Josh is looking to get a new car because he decided he was spending too much on gas, and over the past year he found that he drove 7,700 miles, and at current gas prices of $4.5 he was getting about 27 miles per gallon, To determine, if he bought a vehicle that realizes 33 miles per gallon, what might be a reasonable estimate of monthly gas costs, the following calculation must be made:

  • 27 = 100
  • 33 = X
  • 3300 / 27 = X
  • 122.22 = X
  • 122.22 = 100
  • 100 = X
  • 10000 / 122.22 = X
  • 81.81 = X
  • (7700 / 33) x 4.5 = X
  • 233.33 x 4.5 = X
  • 1050 = X

Therefore, Josh's monthly fuel expenses are $1,050.
