Answer:

D. The intersection of the angle bisectors.

Step-by-step explanation:

The incenter is equidistant from each of the sides of the triangle. An angle bisector is the set of points equidistant from the sides, so the incenter is the place where the angle bisectors meet.

Which ordered pair is a solution of the equation? −7x+3y=2

lana66690 [7]

Answer:

(-2/7, 2/3)

step-by-step explanation:
-7x + 3y = 2
x = 0
-7(0) + 3y = 2
3y = 2
/3 /3
y = 2/3
y = 0
-7x + 3(0) = 2
-7x = 2
/-7 /-7
x = -2/7
(-2/7, 2/3)

A man has mislaid his wallet. He thinks there is a 0.4 chance that the wallet is somewhere in his bedroom, a 0.1 chance it is in

lana [24]

Answer:

a. Probability = 0.15

b. Probability = 0.3

Step-by-step explanation:

Given

$P(Bedroom) = 0.4$

$P(Kitchen) = 0.1$

$P(Bathroom) = 0.2$

$P(Living\ room) = 0.15$

Solving (a): Probability of being somewhere else

This is calculated by subtracting the sum of given probabilities from 1.

$Probability = 1 - (0.4 + 0.1 + 0.2 + 0.15)$

$Probability = 1 - 0.85$

$Probability = 0.15$

Solving (b): Probability of being in bedroom or kitchen

This is calculated as:

$Probability = P(Bedroom) + P(Kitchen)$

$Probability = 0.2 + 0.1$

$Probability = 0.3$

Find the volume of a right circular cone that has a height of 14.3 ft and a base with a diameter of 17.2 ft. Round your answer t

saveliy_v [14]

Answer:

Volume of the given cone is 1107.6 cubic feet.

Step-by-step explanation:

Formula to get the volume of a right circular cone is,

V = $\frac{1}{3}\pi r^{2}h$

Here r = radius of the circular base

h = height of the cone

Now we put the values in the given formula

Volume = $\frac{1}{3}\pi (8.6)^2(14.3)$ [ radius = $\frac{17.2}{2}=8.6$ ]

= $\frac{1057.628\pi }{3}$

= 1107.55

≈ 1107.6 cubic feet

Therefore, volume of the given cone is 1107.6 cubic feet.

Answer:

C- $1.70

Step-by-step explanation:

First, put the numbers in order from least to greatest. You then need to separate the numbers in the middle. The middle numbers are 1.65 and 1.75.

You then need to find the number that is in between 1.65 and 1.75 that is common and stays the same. The middle number would be 1.70, so that's your answer.
