Answer:

44, 58, 74

Step-by-step explanation:

you add up by 2´s.

Which means, 4+4=8, 8+6=14, 14+8=22, 22+10=32

4,6,8,10,12,14,16

Answer:

m∠B = 95°

Scalene

Step-by-step explanation:

by definition, internal angles in a triangle must add up to 180°

in this case,

∠A + ∠B + ∠C = 180°

we are given ∠C = 55° and ∠A = 30°

30° + ∠B + 55° = 180°

∠B = 180 - 55 - 30 = 95° (Answer)

We can see that all 3 angles of the triangle are different. And hence we can conclude that all 3 sides of the triangle are different length (i.e it is not equilateral or isosceles). Hence it is a scalene triangle.

suppose the mean 40 yard dash time of a perfessional football player is 4.41 seconds with a standard deviation of 0.15 seconds.

I am Lyosha [343]

The percent of runners between these two times is 47.72.

We find the z-scores associated with each end of this interval using the formula
z=(X-μ)/σ

For the lower end,
z=(4.11-4.41)/0.15 = -0.3/0.15 = -2

Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this score is 0.0228.

For the upper end:
z=(4.41-4.41)/0.15 = 0/0.15 = 0

Using a z-table we see that the area to the left of, less than, this score is 0.5000.

We want the area between these times, so we subtract:
0.5000-0.0228 = 0.4772

This corresponds with 47.72%.

which of the following shows the graphical representation of the solution for the one-variable linear equation 2x-1=3

Andrej [43]

For this case we have the following equation:

$2x-1 = 3$

If we add 1 to both sides of the equation we have:

$2x = 3 + 1\\2x = 4$

Dividing between 2 on both sides of the equation we have:

$x = \frac {4} {2}\\x = 2$

The graph of the solution is shown in the attached figure.

A certain type of brass contains 65% copper. How many pounds of copper are contained in 120 pounds of the brass?

soldier1979 [14.2K]

The amount of cooper that are contained in 120 pounds of the brass is equal to 78 pounds.

Let the amount of copper be C.

<u>Given the following data:</u>

Quantity of brass = 120 pounds

Percentage of copper = 65%

To calculate the amount of cooper that are contained in 120 pounds of the brass:

In this this exercise, you're required to determined how many pounds of copper can be found in 120 pounds of the brass. Thus, we would solve for the percentage of copper contained in this type of brass.

$Copper = \frac{65}{100} \times 120\\\\Copper = 0.65 \times 120$

Copper, C = 78 pounds
