It’s 5 to 10 seconds EXPLANATION: if you were to go from 49 feet in the air to 19 feet in the air, which means you descended, You would’ve gone -30 feet in 5 seconds. This means that for you to go from 19 to 20 feet in 5 seconds, you would’ve gone through the least change.

One end of a ladder 32 feet long is placed 10 feet from the outer wall of a building that stands on the ground level. How far up
ladessa [460]

Answer:

30 ft

Step-by-step explanation:

This is a classic right triangle problem, where the length of the ladder represents the hypotenuse, where the ladder is lengthwise from the building is the base of the triangle, and what we are looking for is the height of the triangle.  Pythagorean's Theorem will help us find this length.

32^2-10^2=y^2 so

1024 - 100 = y^2 and

y = 30.4 so 30 feet

Examine the intersection of these lines:
Soloha48 [4]

Answer:

  • ∠B and ∠F
  • ∠F and ∠E . . . already listed in the problem statement, so may not be considered an "other pair"

Step-by-step explanation:

∠C and ∠F are vertical angles, so are congruent. Then any angle complementary to one of those will also be complementary to the other.

Likewise, ∠B and ∠E are vertical angles and congruent. Any angle complementary to one of them will also be complementary to the other. Here, ∠E and ∠F are listed as complementary, so we know ∠B and ∠F will be also.

What is the area of a trapezoid that has the bases of 1 1/4ft and 14 inches and a height of 3 inches.
Rom4ik [11]

The area of the trapezoid is 43.5 inches²

Step-by-step explanation:

The formula of the area of a trapezoid is A=\frac{1}{2}(b_{1}+b_{2})h , where:

  • b_{1} and b_{2} are the two parallel bases
  • h is its height

∵ b_{1} = 1\frac{1}{4} feet

∵ b_{2} = 14 inches

∵ h = 3 inches

- Change the length of b_{1} from feet to inches

∵ 1 foot = 12 inches

∴ 1\frac{1}{4} feet = 1\frac{1}{4} × 12 = 15 inches

∴ b_{1} = 15 inches

Substitute the values of b_{1} , b_{2} and h in the

formula of the area

∴ A=\frac{1}{2}(15+14)(3)

∴ A = 43.5 inches²

The area of the trapezoid is 43.5 inches²
