The two angles are vertical angles, which means they are the same.

Set the two equations to equal and solve:

2x +2 = 3x -52

Subtract 2x from each side:

2 = x -52

Add 52 to each side:

x = 54

Using exponent laws please answer this

hram777 [196]

Answer:

see below

Step-by-step explanation:

In addition to the exponent rule ...

(a^b)^c = a^(bc)

it is helpful to know the first few powers of some small integers.

5^3 = 125

9^2 = 81

4^3 = 64

2^6 = 64

125^3 = (5^3)^3 = 5^(3·3) = 5^9
81^7 = (9^2)^7 = 9^(2·7) = 9^14
(1/64)^3 = ((1/4)^3)^3 = (1/4)^(3·3) = (1/4)^9
(1/64)^3 = ((1/2)^6)^3 = (1/2)^(6·3) = (1/2)^18

A carpenter has two lengths of wood; one is 108cm long and the other is 72cm long. He wants to cut them up to produce smaller pi

Y_Kistochka [10]

Answer:

36 centimeters.

Step-by-step explanation:

1. To solve this problem you must find the Greatest common factor.

2. List the prime factor of 108 and 72:

$108:(2)(2)(3)(3)(3)=(2^{2})(3^{3})\\ 72:(2)(2)(2)(3)(3)=(2^{3})(3^{2})$

3. Now, you must choose the common prime numbers with the lowest exponents and multiply them:

$(2^{2})(3^{2})=(4)(9)=36$

Choose an American household at random, and let the random variable X be the number of cars (including SUVs and light trucks) th

PilotLPTM [1.2K]

Answer:

19% of households have more cars than the garage can hold

Step-by-step explanation:

We are given the following distribution for the number of cars owned by a family.

Number of cars X: 0 1 2 3 4 5 6

Probability: 0.07 0.31 0.43 0.12 0.04 0.02 0.01

We have to find the percentage of households have more cars than the garage can hold.

A garage can hold two cars. Thus, the household with more than two cars are the households that have more cars than the garage can hold.

The given distribution is a discrete probability distribution.

Thus, we evaluate:

$P(x\geq 3) = P(x+3) + P(x+4) + P(x+5) + P(x+6)\\P(x\geq 3) = 0.12 +0.04+ 0.02 +0.01 = 0.19\\P(x\geq 3) = 19\%$

Thus, 19% of households have more cars than the garage can hold.
