Answer:

619.5cm2

Step-by-step explanation:

Based on what you defined as the parallel sides been 26cm and 33cm and the height been 21cm.

Hence the are of trapezium is half sum of the parallel sides × height.

Expressed mathematically we have:

1/2( 26 +33) × 21 = 1/2 ( 59) × 21 = (59×21)/2= 619.5cm2

A vehicle uses 1 1/8 gallons of gasoline to travel 13 1/2 miles. At this rate, how many miles can the vehicle travel per gallon
valentina_108 [34]

Answer:

12 miles

Step-by-step explanation:

The problem above is related to the topic on "Equivalent Ratios." The missing term above is <em>"the number of miles that the vehicle can travel per gallon of gasoline."</em> In order to find this term, you have to use the "cross products."

Let n be the missing term.

  • 1\frac{1}{8} gallons/13\frac{1}{2} miles = \frac{1 gallon}{n}
  • \frac{9}{8} gallons/\frac{27}{2} miles = \frac{1 gallon}{n}
  • \frac{9}{8} x n = \frac{27}{2} x 1 gallon
  • n = \frac{27}{2} ÷ \frac{9}{8}
  • n = \frac{27}{2} x \frac{8}{9}
  • n = 12 miles

Therefore, the vehicle can travel 12 miles per gallon of gasoline.

2+ (-3)^2 - (-1)<br><br> please explain! :3
Ugo [173]

Answer:

12

Step-by-step explanation:

Hello!

First of all you have to understand the order of operations.

PEMDAS

Parenthesis, Exponent, Multiplication/Divison, Addition, Subtraction.

From this you can see that we first have to deal with the exponent, then multiplication, then the addition.

So we get 2+9-(-1)

The 9 is from -3^2

2+9+1

11+1

12.

Hope this helps!
