Answers

Answer 1
Answer:

5 pizza cost $60

9 pizzas cost $ x

now solve for x

x= (9*60)/5

x= 540/5

x= 108

9 pizzas will cost $108


I hope that's help Acan !

What is the measure of x

Answers

the answer is 36 because 180-108 is 72. 72=2x . so to find x, you divide 72 by 2, which gives you 36
X is equal to 36 from the solution in the image. Hope I was able to help.

Roll dice and flip coin P(heads and 3)
a. 1/12 or b. 1/4
please help !!

4 blue 2 green 6 red
P(blue then red)

a. 2/11 or b. 1/6

PLEASE HELP YOU GUYS

Answers

Roll dice and flip coin:
Probability of rolling a cube and getting a 3 = 1/6 .
Probability of flipping a coin and getting HEADS = 1/2 .

Probability of both = (1/6) x (1/2) .
You do the multiplication.

4 blue, 2 green, 6 red
Probability of a blue on the first draw = 4 out of 12 marbles = 1/3 .
Without putting the blue back in ...
Probability of a red on the next draw = 6 out of 11 marbles = 6/11 .

Probability of both = (1/3) x (6/11) .
You do the multiplication.

A triangle is inside a circle where the triangle's base is on the circle's diameter as shown.What is the area of the shaded region?

Use 3.14 for π .

Enter your answer as a decimal in the box.

Answers

Answer:

A_(shaded)= 136.96 ft^(2)

Step-by-step explanation:

We will find the shaded area if we subtract the area of the triangle from the area of the circle.

We know that the area of the circle is defined as

A= \pi r^(2)

Where r is half the diameter, that is

r=(16ft)/(2)=8ft

The area of the circle is

A= \pi r^(2)\nA= 3.14 (8ft)^(2) =200.96ft^(2)

Now, we have to find the area of the triangle, which is defined as

A_(\triangle) =(bh)/(2)

Where b is the base of 16 feet, and h is the height of the triangle which is on the radius. So, we have b=16ft and h=8ft.

The area of the triangle is

A_(\triangle) =(16ft(8ft))/(2)=64ft^(2)

Now, the shaded is the difference as we said before, that is

A_(shaded)=A-A_(\triangle)

Replacing both areas, we have

A_(shaded)=200.96 ft^(2) - 64ft^(2)= 136.96 ft^(2)

Therefore, the shaded area is A_(shaded)= 136.96 ft^(2)
area of a circle=pi x r^2= 3.14 x 8^2(half of the radius)=3.14 x 64=200.96

area of triangle= 1/2 bh=1/2(16)(8)=1/2(128)=64

200.96-64=136.96 sq.ft

Can someone explain to me how to do this

Angles on a straight line add up to 180°, so:

x + 60 = 180

x = 180 - 60

x = 120°
60+60+60=180
180/60=30
x=30
