PLEASE HELP ASAP I’LL MARK BRAINLIEST Find the area of the figure.

Sonbull [250]

Area of a semicircle is 1/2* πr^2
Area of a square is s^2

Square’s area: 4mm^2

The radius is 3mm
Plug into the equation

1/2* π(3^2)
1/2* π(9)

We can use 3.14 as an estimate of pi

1/2*28.26

14.13mm^2

Now just add them both

Total area 18.13mm^2

the temper ire of chicken soup is 192.7 F as it cools the temperature of the soup decreases 2.3 what is the temperature of the s

ad-work [718]

The temperature of soup after 25 minutes is $135.2^{\circ}\ F$

Solution:

The temperature of chicken soup is 192.7°F

As it cools, the temperature of the soup decreases 2.3°F per minute

Let the initial temperature be $T_0$

Let "t" be the time for rate of decrease

Set up an equation

Temperature = Initial temperature - decrease in temperature

Decrease in temperature = rate of decrease x time

Therefore,

$T = T_0-2.3t$

To find the temperature of soup after 25 minutes, substitute t = 25

$T = 192.7 - 2.3 (25)\\\\T = 192.7 -57.5\\\\T = 135.2$

Thus the temperature of soup after 25 minutes is $135.2^{\circ}\ F$

rjkz [21]

$2.25y + 7.25z + 11.25 \geq 35 \\ y = 2 \\ z = 3 \\ 2.25(2) + 7.25(3) + 11.25 \geq 35 \\ 4.50 + 21.75 + 11.25 \geq 35 \\ 37.5 \geq 35$
The answer will be the third one: Yes, because the total will be $37.50.
