A rectangle with an area of 47 m² is dilated by a factor of 7. What is the area of the dilated rectangle?

1 answer:

8 0

We already know that the area of the rectangle increased by a square of the factor 7. So the dilated area of it (which we will call "Ad"), is:

Ad= (47)(7^2)
Ad= 47x49
Ad= 2303 m^2

What is the area of the dilated rectangle? The area of the dilated rectangle is 2303 m^2.

In triangle JKL, if angle J is seven less than angle L and angle K is 21 less than twice angle L, find the measure of each angle

saul85 [17]

Answer:

L = 52°

J = 45°

K = 83°

Step-by-step explanation:

J = L - 7

K = 2L - 21

J + K + L = 180°

∴ (L - 7) + (2L - 21) + L = 180

4L - 28 = 180

4L = 208

L = 52°

J = 52 - 7 = 45°

K = 2 x 52 - 21 = 83°

Mike traveled from the school to the mall and then from the mall to the library. Henry traveled from the school to the library.

Natalija [7]

Answer:

12 miles

Step-by-step explanation:

From the graph given :

Mike's travel :

School to Mall= 16 miles

Mall to Library = 30 miles

Total travel = 16 + 30 = 46 miles

Henry's travel :

From school to Library = Hypotenus :

Distance can be obtained using Pythagoras :

Hypotenus = √(opposite² + adjacent²)

Hypotenus = √(30² + 16²)

Hypotenus = √1156

Hypotenus = 34 miles

Difference in Distance covered :

(46 miles - 34 miles) = 12 miles
