Answer:
anything with a slope of 8/7
Step-by-step explanation:
Answer:
1. x = 10
2. x = 8
3. x = 7
Step-by-step explanation:
1. Sum of Angles in a triangle = 180
(6x + 3) + (5x - 7) + 74 = 180
11x - 4 + 74 = 180
11x + 70 = 180
Subtract 70 from both sides
11x = 110
Divide both sides by 11
x = 10
2. (8x + 1) + (7x + 14) + 45 = 180
15x + 15 + 45 = 180
15x + 60 = 180
Subtract 60 from both sides
15x = 120
Divide both sides by 15
x = 8
3. We first have to get the 3rd angle: 180 - Exterior angle = 3rd angle
180 - 118 = 62
Now we can find the value of x
10x + (6 + 6x) + 62 = 180
16x + 68 = 180
Subtract 68 from both sides
16x = 112
Divide both sides by 16
x = 7
Hey!
The formula of direct variation is y = kx. So we know that p = kr^2
Hint: after it says varies, it's basically the equal sign.
so we can set it up
56 = 4^2k
56=16k
now we want k alone so we have to divide 16 on both sides
k=3.5
We can now solve for p like it asks
p = 3.5*6^2
p=126
There's your answer!
Hope this helps!
Answer:
B) 2771 cubic centimeter
Step-by-step explanation:
first find the volume of the cylinder
V=πr^2h
V=3.14*7^2*26
V=4002.39
then find the volume of the cone
V=πr^2h
/3
V=3.14*7^2*24/3
V=1231.5
subtract the volume of the cone from the cylinder
4002.39-1231.5
2770.89
round to the nearest whole number
2771
Figure=1rectangle+2 semicircles
1semicircle=1/2circle
2 (1/2 circles)=1 circle
figure=1 rectangle+1 circle
area of rectangle=legnth times width
area of circle=pir^2
so the width of the rectangle=diameter of the circle
widht=4
diameter=2r
d/2=r
width=d=4
4/2=r=2
area of circle=3.14 times 2^2
are of circle=3.14 times 4
aera of circle=12.56
area of rectangle=11 times 4
area=44
total=add them up
12.56+44=56.56 cm^2
