Answer:

  5 ft

Step-by-step explanation:

You are given the area and base lengths of a trapezoid and asked for its height. The formula for the area of a trapezoid is useful.

  A = (1/2)(b1 +b2)h

Filling in the given information, you have ...

  30 ft² = (1/2)(4 ft +8 ft)h

  30 ft² = (6 ft)h . . . . . . . . . . . simplify

  h = (30 ft²)/(6 ft) = 5 ft . . . . divide by the coefficient of h

The height of the trapezoid is 5 feet.

An airplane takes off at a speed S of 226 mph at an angle of 18° with the horizontal. Resolve the vector S into components.

Answers

Velocity=226mph

Angle made with horizontal= 18°

The vector components would be [tex] 226~sin18° \hat{j} + 226~cos18° \hat{i} [/tex]

The vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°

What is a Vector ?

An parameter that has both magnitude and direction is called a vector.

It is given that

Speed S = 226 mph

Angle = 18 degree with the horizontal

The vector component are

[tex]\rm v_x , v_y[/tex]

here these are x and y components of the vector

V is the magnitude = |v| = 226

The vector component is given by

cos [tex]\rm \theta[/tex] = [tex]\rm v_x[/tex] / |v|

[tex]\rm v_x[/tex] = 226 cos 18°

[tex]\rm v_y[/tex] = 226 sin 18°

Therefore the vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°

On a flight,
3/10
of the passengers were children. There were
60 children on the flight. How many passengers were on
the plane?

Answers

Answer:

There were 200 passengers on the plane.

Step-by-step explanation:

1. 3/10  of the passengers were children -> 30% of the passengers were children

2. 60 children on the flight 30% of passengers = 60 people

divide by 3 -> 10% of passengers = 20 people

multiply by 10 -> 100% of passengers = 200 people.

If you can buy 48 plaintains for $24 then how many can you buy with $4 ?

Answers

Answer:

8 plantains

Step-by-step explanation:

48=$24

x=. $4

192=24x , x= 192÷24= 8

Answer:

8 plantains

Step-by-step explanation:

Cost and number of plantains are in proportion

Number of plantains that can be bought for $ 4 be 'x'

48 : 24 :: x : 4

Product of means = product of extremes

24 * x = 48*4

       [tex]x = \frac{48*4}{24}[/tex]

      x = 2 * 4

      x = 8

m<4 = 17x° and m<2 = (9x+40)º
Find x and the measure of each angle.

Answers

Answer:

X = 5 u

m∠4 = 85º

m∠ = 85º

Step-by-step explanation:

17x = 9x + 40

17x-9x = 40

8x = 40

x = 40/8

x = 5

m∠4 = (17x)º = (17*5)º = 85º

m∠ = (9x+40)º = (9*5 + 40)º = (45 + 40)º = 85º

Amir can run 15 kilometers in one hour. How many kilometers can Amir run per minute? There are 60 minutes in 1 hour.

Answers

The answer is .25 kilometers a minute.

This is because [tex]speed = \frac{distance}{time}[/tex] so you need substitute then divide to find the answer

You can check this answer by doing 15÷60 which comes out to .25 km a minute.

Answer:0.25m per minute

Step-by-step explanation:

You divided the 15 by the 60 since 15 is the km and 60 minutes and you want to know how far can she run in minutes

What is the sum of 50.249 + 21.3

Answers

Answer:

71.549

Step-by-step explanation:

Answer:

The sum of 50.249 + 21.3 is 71.549.

Step-by-step explanation:

50.249 + 21.3 can be written as (50 + 20) + (0 + 1) + (0.2 + 0.3) + 0.049, which makes calculating the sum easier. 50 + 20 = 70, 0 + 1 = 1, 0.2 + 0.3 = 0.5, and you still have a 0.049. Add the numbers all together and you'll get that the sum of 50.249 and 21.3 is 70 + 1 + 0.5 + 0.049 or 71.549.
