Answer:
the volume of the cone is
15in^3
Step-by-step explanation:
Step one:
parameters of the cone
radius r = 3 in
height h= 5 in
Step two:
the expression for the volume of the cone is
V= 1/3πr^2h

Answer: 16
Step-by-step explanation:
Solution for What is 5 percent of 320:
5 percent *320 =
(5:100)*320 =
(5*320):100 =
1600:100 = 16
Now we have: 5 percent of 320 = 16
Can someone tell me the slope ?
Answer:
slope = 4
Step-by-step explanation:
We can find the slope of a line when knowing 2 points by using the slope formula, [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of the first point, respectively. [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of the second point, respectively.
The two points we have are (2,8) and (0,0). So, in this case, [tex]x_1[/tex] = 2, [tex]y_1[/tex] = 8, [tex]x_2[/tex] = 0, and [tex]y_2[/tex] = 0. Let's substitute those values into the formula and solve to get the slope:
[tex]m =[/tex] [tex]\frac{0-8}{0-2}[/tex]
[tex]\frac{-8}{-2}[/tex]
[tex]4[/tex]
So, the slope is 4.
Mark tried to pour 36 ounces of tea into 3 cups. after filling the cup to the top, there were still 13.5 ounces left in his tea pot. if each cup is the same size how much is in the tea cup? HELP PLEASE!
Answer:
its 12
Step-by-step explanation:
12 oz
Answer:
22.5/3
Step-by-step explanation:
Hey, the idea is to set up an equation that you can solve
36 ounces of tea = 3 cups(some ounces of tea) + 13.5 ounces left
Now just solve for how much tea is in each cup.
36-13.5 = 3(X)
3X = 22.5
x = 22.5/3

Answer:
1. x = 21°
2. x = 30°
3. x = 7°
5 x = 3
Step-by-step explanation:
Solving for x
1. 15+ 5x + 60° = 180°
75 + 5x = 180°
5x = 180 - 75
5x = 105
x = 105/5
x = 21°
2. These angle are vertical angles
Hence:
13x - 5 = 125°
13x = 125° + 5
13x = 130
x = 130/3
x = 30°
3. 8x - 1 = 55°
8x = 55 + 1
8x = 56
x = 56/8
x = 7°
5. These angles are angles in a straight line
17x - 1 + 130° = 180°
17x + 129° = 180°
17x = 180° - 129°
17x = 51
x = 51/17
x = 3°

16. Find the length of the median CD.
17. Find the coordinates of E, the midpoint of BC
18. Find the length of the median AE.
Step-by-step explanation:
16. Length of a line = sqaureroot of ((x1-x0)^2 - (y1- y0)^2)
C (2,-3) D (6,3)
CD = sqaureroot of ((6-2)^2 + (3-(-3))^2)
CD = sqaureroot of ( 16 + 36)
CD = sqaureroot of 52 = 2 root 13 = length
17. E (5, - 1) because the point is under the x axis.
Midpoint = ((x1+ x0)/2 , (y1 +y0) /2)
B (8,1) C (2, - 3)
Midpoint of BC = ((2+8)/2 , (-3+1)/2)
= (10/2 , - 2/2)
= (5, - 1)
18. Length of AE
A (4,5) E(5,-1)
Square root of ((5-4)^2 + (-1-5)^2)
Square root of (1^2 + - 6^2)
Square root of ( 1 + 36)
Square root of 37 = root 37

A. 24.18%
B. 80.53%
C. 22%
D. 19.47%
Answer:
D. 19.47

Answer:
19.47% to the nearest hundredth.
Step-by-step explanation:
Value of the error = 113 - 91 = 22.
Percent error = (22/113) * 100
= 19.47.
