1 answer:
Schach [20]2 years ago

Solution:

<u>We know that:</u>

  • Area of trapezoid = (a₁ + a₂)h/2
  • a₁ = 8 inches; a₂ = 8 + 4 + 4 inches; Height = 6 in.

<u>This means that:</u>

  • Area of trapezoid = (8 + 8 + 4 + 4)6/2

Step-by step calculations:

<u>Simplify the numerator:</u>

  • Area of trapezoid = (8 + 8 + 4 + 4)6/2
  • => Area of trapezoid = (24)6/2

<u>Cancel the denominator:</u>

  • => Area of trapezoid = (24)3

<u>Simplify the term:</u>

  • => Area of trapezoid = 72 in²

PLEASE HELP!!!!!!! A family has two cars. The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a
Marianna [84]

Answer:

The answer to your question is car 1 = 30 gal and car 1 = 20 gal

Step-by-step explanation:

car 1 = a

car 2 = b

Efficiency of car 1 = 35 mi/gal

Efficiency for car 2 = 20 mi/gal

Total distance = 1450

Total gas consumption = 50 gal

Equations

                          35a + 20b = 1450            ------- (I)

                             a   +     b =  50               ------- (II)

Solve by elimination

Multiply equation II by -35

                          35a  + 20b  = 1450

                         -35a  - 35b   = -1750

Simplify

                            0    - 15b    =  -300

Solve for b

                                        b =  -300/-15

Result

                                        b = 20

Substitute b in equation II to find a

                               a +  20  = 50

Solve for a

                               a  = 50 -20

Result

                               a  = 30

Using the distance formula, find the distance between two points. (6, 0) (-5, 4)
Ipatiy [6.2K]

Answer:

11.7046999

Step-by-step explanation:

using the distance formula (d=√(x₂ -x₁)² + (y₂-y₁)²), we can plug in the two points to find the distance between them:

d=√(6-(-5)² + (0-4)²

d=√(11)²+ (-4)²

d=√121+16

d=√137

d approximately equal to (≈) 11.7046999 or 11.7 or 11

5. A family spends T 600.00 a day for food which is 40% of the
BabaBlast [244]

Answer:

<h3>15%</h3>

Step-by-step explanation:

<h3>First , We will solve their daily Income </h3>

• Income = spends / rate

• Income = 600 / 40%

• Income = 600 / 0 .40%

• Income = 1500

Thus , Their daily Income is 1500 . Now ,We will solve for the rate of the Allowance .

• Rate = spent / Income

• Rate = 225 / 1500

• Rate = 0.15

• Rate = 15%

Therefore, the percent of the family's daily Income of the Allowance of their children's is 15%
