Answer:

The base angles are 64. The top angle is 52

Step-by-step explanation:

Since this is an icoseles triangle, the base angles are equal so:

8x - 16 = 6x + 4

8x - 6x = 4 + 16

2x = 20

x = 10

8x - 16

8(10) - 16

80 - 16

The top angle (x)

x + 64 + 64 = 180

x + 128 = 180

x = 52

Step-by-step explanation:

We assume that ...

SU = ST +TU

133 = (9x-5) +(5x+12)

126 = 14x . . . . . subtract 7, collect terms

9 = x . . . . . . . . . divide by 14

I have a flower vase with a 6 " diameter and is 12 " tall I want to fill it 2/3 of the way full how many cubic inches will I fil

RSB [31]

Answer:

$72\pi\ in^{3}$

Step-by-step explanation:

step 1

Calculate the volume of the cylinder (flower vase)

The volume is equal to

$V=\pi r^{2}h$

we have

$r=6/2=3\ in$ -----> the radius is half the diameter

$h=12\ in$

substitute the values

$V=\pi (3)^{2}(12)=108\pi\ in^{3}$ ------> exact value

step 2

Calculate 2/3 of the volume

$V=(2/3)108\pi=72\pi\ in^{3}$

fenix001 [56]

Answer:

Step-by-step explanation:

If R(-2), then x = -2. Just plug in -2 for x. -2^2 - 3(-2) - 1 = 4 + 6 - 1 = 10 - 1 = 9. The answer is 9.

P ( rolling a 5 or rolling a 4 ) on a die or fair number cube. Find the probability of these mutually exclusive events.

pentagon [3]

Answer: I believe it the probability of this would be 1/3.

Step-by-step explanation: This is mainly because if the chances of rolling a 5 or a 4 on a die or fair numbered cube, which contains 6 sides, then landing on 5 or 4 would be 2 out of the six chances it would land on those two numbers. Hope this helps!
