The semicircle below has diameter $20$. Find the area of the blue region.

The Semicircle Below Has Diameter $20$. Find The Area Of The Blue Region.

Answers

Answer 1
We subtract the area of the triangle from the area of the semicircle
The Semicircle Below Has Diameter $20$. Find The Area Of The Blue Region.
Answer 2

Area of the blue region is 61 units²

Area of semi circlearea = π / 2 r²

Therefore,

r = radius

Area of the blue region  = area of semi circle - area of triangle

Therefore,

area of triangle = 1/bh

where

b = base

h = height

Therefore,

area of triangle = 1 / 2 × 12 × 16 = 96 units²

area of semi circle = 3.14 × 10² /  2 = 157 units²

Area of the blue region  = 157 - 96 = 61 unit²

The temperature of chicken soup is 192.7°F. As it cools, the temperature of the soup decreases 2.3°F per minute. What is the temperature in degrees Fahrenheit of the soup after 25 minutes?

Answers

Answer: 135.2 °F

Step-by-step explanation:

The temperature decreases at a rate of 2.3 °F per minute.

This means that in 25 minutes, the temperature would have reduced by:

= 2.3 * 25

= 57.5°F

If the original temperature was 192.7 °F, the temperature after 25 minutes will be:

= 192.7 - 57.5

= 135.2 °F

How many flowers, spaced every 4 in., are needed to surround a circular garden with a 100-ft radius?

Answers

Answer:

1885 flowers

Step-by-step explanation:

Given that:

Radius, r of circle = 100 feets

The Circumference of the circke is thus ; 2πr

C = 2 * π * 100

C = 628.31853 feets

Converting feets to inches

1 foot = 12 inches

628.31853 feets = 628.31853 * 12 = 7539.8223 inches

If flowers are spaced at 4 inches :

Number of flowers that can be planted :

Circumference of circle / spacing

7539.8223 / 4

= 1884.9555 flowers

= 1885 flowers

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of the given function is:

f(x) = -6 x 7.5x

We can rewrite this in the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept:

f(x) = -6 x 7.5x + 0 (since the x-term has a coefficient of 0)

f(x) = -45x + 0

So, the slope of the line is -45 and the y-intercept is 0.

Therefore,

The value of the y-intercept is 0.

Hello There!

Formula for area of a triangle [tex]A =\frac{1}{2}bh[/tex]

where b = base and h = height

the dimensions of the triangle shown are b = 1.5 and h = 1.3

given the dimensions all we have to do is plug in the values into the formula

so

[tex]A=\frac{1}{2} 1.3*1.5\\1.3*1.5=1.95\\\\\frac{1.95}{2} =0.975[/tex]

so we can conclude that the area of the triangle is

11) Nick & John ordered burritos & tacos for lunch. Nick
ordered 3 burritos & 4 tacos for $11.33. John ordered 9
burritos & 5 tacos for $23.56. Find the cost of one
burrito & one taco.

Answers

Answer:

taco:  $1.49 each

burrito:  $1.79 each

Step-by-step explanation:

Let b = cost of one burrito

     t =  cost of one taco

(1)     3b  + 4t  = 11.33              (2)     9b + 5t = 23.56

Multiply (1) by -3 and add to (2)     -9b - 12t = 33.99

                                                              - 7t = - 10.43

                                                                  t = 1.49

       3b + 4(1.49) = 11.33

          3b + 5.96 = 11.33

                  3b = 5.37

                    b = 1.79
