Answer:
66+90+x=180
so x is = 180-156=24
Answer:
24°
Step-by-step explanation:
The answer is 24 ° because you can tell based off of the ∠ACD that it is a 90 ° angle and you can tell that line AD and line AB are perpendicular which means that they form two 90 ° angles. You know that ∠DCE is 66 ° meaning that the rest of the right angle must be 24 °.

True or False? A circle could be circumscribed about the quadrilateral below. c 80° A. True 95° B. False 85°
Answer:
False
Step-by-step explanation:
The circle could be circumscribed about the quadrilateral is false because the sum of the opposite angles is not 180 degrees.
What is quadrilateral?It is defined as the four-sided polygon in geometry having four edges and four corners. Two pairs of congruent sides, and it has one pair of opposite congruent angles.
As we know, the circle can be circumscribed around a quadrilateral if and only if the quadrilateral's opposite angles add up to 180 degrees.
But,
80 + 85 < 180
100 + 95 > 180
Thus, the circle could be circumscribed about the quadrilateral is false because the sum of the opposite angles is not 180 degrees.

What expression represents the volume of the cone, in
cubic units?
xx 3
O 2013
O 47x3
Answer:
A.
Step-by-step explanation:
Volume of a cone = ⅓πr²h
Where,
r = x
h = 2x
Plug in the values into the formula for volume
Volume = ⅓*π*x²*2x
Volume = ⅓*π*2x³
Volume = (1*π*2x³)/3
Volume = [tex] \frac{2\pi x^3}{3} [/tex]

Find the probability that a randomly chosen point is located within the shaded region. Write your answer as a decimal, and
round to the nearest thousandth, if necessary.

3
Probability
Answer:
[tex]Probability = 0.25[/tex]
Step-by-step explanation:
Given
The attached shape
Required
Probability of locating within the shaded region
First, calculated the area of the shaded region
[tex]A_1 = 0.5 * base * height[/tex]
Where
[tex]base = 8cm\\ height = 6cm[/tex] --- given
So:
[tex]A_1 = 0.5 * 8cm* 6cm[/tex]
[tex]A_1 = 24cm^2[/tex]
Next, calculated the area of the complete rectangle
[tex]A_2 = Length* Width[/tex]
Where
[tex]Width = 12cm\\ Length = 8cm[/tex] --- given
So:
[tex]A_2 = 12cm * 8cm[/tex]
[tex]A_2 = 96cm^2[/tex]
The required probability is:
[tex]Probability = \frac{A_1}{A_2}[/tex]
[tex]Probability = \frac{24cm^2}{96cm^2}[/tex]
[tex]Probability = 0.25[/tex]

Challenge A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, % are pennies and % are dimes. There are more nickels than pennies. How much money does the bag contain?
The bag contains $
Answer:
.
10% of 50 coins is/are 5 coins. So, 5 coins are pennies.
40% of 50 coins is/are 20 coins. So, 20 coins are dimes.
The number of nickels is (5 + 9) = 14, according to the condition.
Then quarters are the rest (50 - 5 - 20 - 14) = 11 coins.
Now you can easily calculate the total and answer the question
Total = 5*1 + 14*5 + 20*10 + 11*25 = 550 cents = $5.50. ANSWER

Step-by-step explanation:
A spinner is divided into many sections of equal size. Some sections are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 12/20. The probability of the arrow landing on a section colored blue is 6/20. What is the probability of the arrow landing on a green-colored section?
Answer:
2/20
Step-by-step explanation:
12 + 6 is 18 so then your remaining would be 2 so your answer should be 2/20!
Answer:
[tex]\frac{2}{20}[/tex]
Step-by-step explanation:
We have 3 sections.
[tex]\frac{12}{20}[/tex][tex]\frac{6}{20}[/tex][tex]\frac{x}{20}[/tex]Since we only have 3 sections, we can add red and blue, and subtract [tex]\frac{20}{20}[/tex]
[tex]\frac{12}{20} + \frac{6}{20} = \frac{18}{20}[/tex]
Subtract:
[tex]\frac{20}{20}-\frac{18}{20} = \frac{2}{20}[/tex]

A rectangular resort pool has a length of 45 feet and a width of 30 feet. A sitting area is attached to the pool and is in the shape of a semicircle with a diameter of 20 feet, as shown below. If the pool is filled to a depth of 5 feet and the sitting area is filled to a depth of 2.5 feet, approximately how much water is contained in both the sitting area and the pool?
Athletic Outfitters packs tennis balls into a cylinder with a diameter of 9.6 centimeters and a height of 39.5 centimeters. Each tennis ball has a diameter of 9.5 centimeters and there are 4tennis balls in each container. Approximately how much extra space is in the container?
Answer:
1 7142.699082ft³ (C)
2 1063.420642cm³ (A)
Step-by-step explanation:
Hey There!
1. So for the first one we want to find the volume of the rectangular pool and the volume of the semi cylinder
The dimension given are
length - 45
width - 30
height - 5
to find the volume we use
[tex]V=lwh[/tex]
[tex]45*30=1350\\1350x5=6750[/tex]
so the volume of the rectangular pool is 6750ft³
now we need to find the volume of the semi cylinder
the dimensions given are
diameter - 20
height - 2.5
so we find the volume by using the volume for a cylinder then dividing by 2
the volume for a cylinder formula is
[tex]V=\pi r^2h[/tex]
r = radius
h = height
to find the radius given the diameter we just divide by 2
20/2=10 so the radius is 10
now we just plug in the values and get
[tex]V=\frac{1}{2} \pi 10^22.5[/tex]
Note: the 1/2 is added because were finding the volume of a semi cylinder
[tex]10^2=100\\100(2.5)=250\\250\pi =785.3981634\\\frac{785.3981634}{2} =392.6990817[/tex]
So the volume of the sitting area is 392.6990817
Now that we have found the volume of each part we add them together to get the answer
[tex]392.6990817+6750=7142.699082[/tex]
2. For the second one we need to find the volume of the cylinder and subtract it by the volume of the tennis ball..s times 4 ( because there are 4 of them)
For the cylinder we are given the dimensions
height - 39.5
diameter - 9.5
Remember this is the formula of the volume of a cylinder
[tex]V=\pi r^2h[/tex]
r =radius
h = height
to convert diameter to radius we divide by 2
9.5/2=4.75
now we plug in the values
[tex]V=\pi 4.75^239.5\\4.75^2=22.5625\\22.565(39.5)=891.21875\\891.21875\pi =2859.100642[/tex]
so the volume of the container is 2859.100642cm³
now we need to find the volume of the tennis ball
to do this we use the formula
[tex]V=\frac{4}{3} \pi r^3[/tex]
we are given the dimensions of
diameter - 9.5
once again to convert to radius we divide by 2
9.5/2=4.75
now we plug in the values
[tex]V=\frac{4}{3} \pi 4.75^3\\4.75^3=107.171875\\107.171875\frac{4}{3} =142.8958333\\142.8958333\pi =448.9205002\\448.9205002(4)=1795.682001[/tex]
So the volume of the tennis bal...ls is 1795.682001
note: i multiplied by 4 because there are 4 tennis bal...ls
our final step is to subtract the volume of the bal...ls from the container
2859.100642-1795.682001=1063.420642
hope this helps :)
