Answer:

a=10

Step-by-step explanation:

The question can be interpreted as

F∝a

If we introduce proportionality constant k, we have

F= k.a

28= k. 7

k= 28/7

k= 4

Then the equation can be written as

F= 4.a

To find, a when F = 40?

F= 4.a

40=4 × a

a= 40/4

a= 10

HELP PLEASE! ONLY 5 MORE MINUTES! Look at the following shape below: Please find the PERIMETER of the following shape using the
Evgen [1.6K]

Answer:

The perimeter is P=73.12\ cm

Step-by-step explanation:

we know that

The perimeter of the figure is equal to the circumference of a semicircle

plus the perimeter of a square minus the diameter of the circle

so

P=\pi r+4(b)-D

we have

r=8\ cm

b=16\ cm

D=16\ cm

The diameter of the circle is equal to the length side of the square

substitute

P=(3.14)(8)+4(16)-16

P=25.12+64-16

P=73.12\ cm
