Can you help me on question 10?!

Answer:

15 because when you add 30 and 45 together, you get 75. There is 90 degrees in that angle, so to get 90 degrees, you need to have 15 more degrees

Answer:

The measure of DAC is 15 degrees.

Step-by-step explanation:

Since there are three angles that make up this 90 degree angle. we need to find the missing angle from the other two. To do this, subtract the known angles from 90 degrees.

[tex]90 - 35 - 40 = 15[/tex]

The measure of the missing angle is 15 degrees.

ALGEBRA METHOD:

You can also use a variable to find the missing measurement.

[tex]45 + 30 + x = 90 \\ 75 + x = 90 \\ x = 15[/tex]

The measure of the angle, x, is equal to 15 degrees.

Step-by-step explanation:

Since we know the total surface area of a prism is equal to the sum of all its faces, i.e., the floor, walls, and roof of a prism. Therefore, the surface area of a prism formula is given as: Total surface area of a prism = 2 x area of the base + perimeter of the base x Height.

Any value of X makes the statement true, meaning the solution is all real numbers.

Answer:

The last one, Half of the employees earn higher than $40,000

Step-by-step explanation:

The MEDIAN, or Middle salary is $40,000. That is the numbed that is right between all of the salaries. So since it is in the middle, then half of the people are above it, therefore it is the last one.

For Example:

Write the linear inequality shown in the graph. The gray area represents the shaded region.

A. y ≤ 3x + 4

B. y ≤ 3x – 4

C. y ≥ 3x + 4

D. y ≥ 3x – 4

Answer: C

Step-by-step explanation:

1. The graph indicates that the line intersect the y-axis at -4.

2. Then, you must choose any point that are located within the region and replace them to see if the inequality is satisfied. Therefore, you have:

Point (0,2)

Answer:

A test of two independent means.

Step-by-step explanation:

The test above is comparing the two independent mean scores (mean before taking her class ; μ1 and mean score after taking her class, μ2. This two mean values are tested to ascertain if there exist any statistical difference between them. This differs from the proportion which is ecekuared by the ratio of success or failure. The single mean and single proportion test only has one group which its mean or proportion is tested.

The null and alternative hypothesis for two independent sample means may be expressed thus :

H0 : μ1 = μ2

Alternative hypothesis

H1 : μ1 ≠ μ2

Answer:

Step-by-step explanation:

From the graph, the initial distance of the cyclist decreases with time before it starts to increase at the same rate.

i. When t = 60 minutes,

distance = (60 -60)

              = 0

ii. When t = 120 minutes,

distance = (120 -60)

               = 20 km

This implies that the endpoint of the cyclist's race was 20 km from the water station which took 60 minutes. So that on meeting the endpoint, the cyclist cycled back towards the water station at the same rate.

Answer:

Sum is 1836.

Step-by-step explanation:

As we know,

average= sum/total numbers

153=sum/12

153*12=sum

sum=1836

Answer:

130/231

Step-by-step explanation:

you just plug in the values of x, y, and z so:

[tex]\frac{-\frac{2}{3}*\frac{5}{7} }{-\frac{11}{13} }[/tex]

start by simplifying the top:

[tex]\frac{-\frac{10}{21}}{-\frac{11}{13} }[/tex]

divide:

[tex]-\frac{10}{21}[/tex]÷[tex]-\frac{11}{13}[/tex]

= [tex]-\frac{10}{21} * -\frac{13}{11}[/tex]

= [tex]\frac{130}{231}[/tex]

Answer:

3y - 16x = -40

Step-by-step explanation:

Given the coordinate points (4,8) and (1, -8).

The point slope form of the equaton is expressed as;

y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

Get the slope

m = -8-8/1-4

m = -16/-3

m = 16/3

Get the required equation using the point (1, -8)

y - (-8) = 16/3 (x-1)

y+8 = 16/3 (x-1)

3(y+8) = 16(x-1)

3y + 24 = 16x - 16

3y - 16x = -16 - 24

3y - 16x = -40

Hence the required equation is 3y - 16x = -40

Answer:

Answer:

24+x

Step-by-step explanation:

We need to find the expression for the following phrase i.e. the total of 24 and a number x.

Total means we need to add two numbers.

i.e.

Expression = 24+x

Hence, this is the required solution.
