A rectangle and an equilateral

Mathematics
1 answer:

Answer:

The area of the rectangle = 50 cm^2.

Step-by-step explanation:

Let the shortest side of the rectangle be x cm.

Perimeter of the rectangle is:

2x + 2(x + 5).

Perimeter of the triangle =  3 * 2x.

As they have the same perimeter:

2x + 2(x + 5) = 3*2x

2x + 2x + 10 = 6x

6x - 2x - 2x = 10

2x = 10

x = 5 cm.

So the area of the rectangle = x(x + 5)

= 5 * 10

= 50 cm^2.

Jami can mow acre 1/6 in 8 minutes If her rate is constant, can Jami mow 1 1/2 acres in one hour? Explain your reasoning
LenaWriter [7]
Time taken by Jami to mow 1/6 acres is 8 minutes=8/60=2/15 hours.
Rate at which Jami is mowing will be:
rate=(number of acres)/(time)=(1/6)/(2/15)
=1/6÷2/15
=1/6×15/2
=5/4 acres/hour
=1.25 acres/hour
From above calculations we conclude that Jami cannot mow 1.5 acres in 1 hour

Help&amp;EXPLAIN <br><br> Don’t use for points or will be reported and I’ll take the points back
anzhelika [568]

Answer:

X=151

Step-by-step explanation:

1. 61+90= 151

-Combine the two given angles

2.180-151= 29

-Subtract the total of the two combined from 180 because all 3 angles of a triangle add up to 180.

-29 is your difference which is also the angle next to X.

3.180-29= 151

-To find angle X you subtract 29 from 180 because angle X and 29 are supplementary angles that add up to 180.

-Therefore X=151
