Answer: 73

Step-by-step explanation:

Setting Up An Equation

The question provides the distances the train traveled in the first 3 hours

T = total distance

A = distance during 1st hour

B = distance during 2nd hour

C = distance during 3rd hour

the total distance traveled is equal to the sum of the distances of the first three hours so our equation would be

T = A + B + C

Solving For B

Since the question asks for the distance during the second hour, we need to find B

It is already given that A = 54, C = 82, and T = 209, so plug in the values and solve for B

T = A + B + C

B = T - A - C

B = 209 - 54 - 82

B = 73

Final Answer

B = 73

Answer:

Step-by-step explanation:

Because the angle with measure 29 degrees and n are a linear pair, their value must add up to 180 degrees. Therefore:

n+29=180

n=180-29

n=151 degrees, or answer choice D

Hope this helps!

Solve the systems of equations.

rewona [7]

Answer:

x = -1 and y = -1

Step-by-step explanation:

Solve 3x+3y=−6;−x+y=0

Steps:

I will solve your system by substitution.

−x+y=0;3x+3y=−6

Step: Solve−x+y=0for y:

−x+y+x=0+x(Add x to both sides)

y=x

Step: Substitutexforyin3x+3y=−6:

3x+3y=−6

3x+3x=−6

6x=−6(Simplify both sides of the equation)

−6

(Divide both sides by 6)

x=−1

Step: Substitute−1forxiny=x:

y=x

y=−1

Answer:

x=−1 and y=−1

Weights of female cats of a certain breed are normally distributed with mean 4.1 kg and standard deviation 0.6 kg.

Diano4ka-milaya [45]

The proportion is 0.4401.

We find z-scores that correspond with both ends of this interval. Z-scores are given using the formula:

$z=\frac{X-\mu}{\sigma}$

For the lower end,

$z=\fracc{3.7-4.1}{0.6}=\frac{-0.4}{0.6}=-0.67$

The proportion of scores to the left of this number is 0.2514.

For the higher end, the z-score is

$z=\frac{4.4-4.1}{0.6}=\frac{0.3}{0.6}=0.5$

The proportion of scores to the left of this number is 0.6915.

To find just the proportion of scores between these two, we subtract;

0.6915-0.2514 = 0.4401.
