(7+c) + 4 simplify the expression explain each step
Answer:
11 + c
Explanation:
In the parenthesis, 7 + c cannot be simplified, so there is no need for them. Now we have 7 + c + 4. Only 7 and 4 can be added. 7 + 4 = 11. The answer is 11 + c.
Answer:
c+11

A pedagogical research institute wanted to test a new method for teaching geometry by assessing whether It helps students achieve higher grades. They decided to conduct a study using A volunteering high school with a total of 750 students At the beginning of the semester, 2 out of the 4 high schools were randomly picked to use the new teaching method, while the remaining 2 schools kept teaching with traditional methods. The first pair had a total of 400 students, and the second pair had a total of 350 students. By the end of the semester, the researchers compared the average scores in the geometry section of the final exam for each pair of schools. What type of statistical study did the researchers use
Answer:
Experimental Statistical Study
Step-by-step explanation:
Of the three types of statistical study, the one used by the researcher in this question is the experimental statistical study and the reason is as follows:
From the question, a study was conducted on a total of 4 high schools; these high schools were further divided into 2 pairs.
Each pair were subjected to or experimented with different method of teachings. At the end of the semester, the average were compared.
This implies that both pairs were experimented based on different teaching methods and the result of the methods were measured in order to determine which of the methods is better.
This type of study is experimental
Answer:
Experiment ; No, because the schools could be very different, meaning the randomization won't smooth out other effects.

Find the slope of the graph
Hi there! Your answer is -1/9
Please see an explanation for a better and clear understanding to your problem.
Any questions about my answer and explanation can be asked through comments!:)
Step-by-step explanation:
[tex] \large \boxed{ m = \frac{y_2-y_1}{x_2-x_1} }[/tex]
The formula above is slope formula. We will be using this to find a slope of a line.
From the graph, there are two points which are (4,0) and (-5,1).
You can either let (4,0) = (x1, y1) or (x2, y2) but I will be letting (-5,1) =(x2, y2)
Substitute the coordinate points in.
[tex] \large{m = \frac{1 - 0}{ - 5 - 4} } \\ \large{m = \frac{1}{ - 9} } \\ \large{m = - \frac{1}{9} }[/tex]
Hence, the slope is - 1/9. If you are curious where m-term comes from, it comes from y = mx+b where m = slope and b = y-intercept.
Mr. Smith is paid $9.50 per hour for fixing watches. Write an expression for the amount of money Mr. Smith earns in h hours. In addition to his hourly rate, Mr. Smith is paid $2.20 for each watch he fixes. Write an expression for his income if he fixes r watches per hour.
Answer:
1. 9.5h
2. 2.2r + 9.5h
Step-by-step explanation:
This is the correct way to write the expression. Based on the order of operations, always solve operations in parentheses first. Here, you'd add 4 + 2, then multiply that sum by 5—in other words, exactly what was written in the original expression.

Angle measures 82.6° less than the measure of its supplementary angle. What is the measure of each angle
Answer:
131.3°, 48.7°
Step-by-step explanation:
Let x represent the larger angle. Then x-82.6 is the smaller one. Their sum is ...
x +(x -82.6) = 180
2x = 262.6
x = 131.3
x -82.6 = 48.7
The two angle measures are 48.7° and 131.3°.
Pls help this is due today ! Find the value x:
Answer:
x = 12
Step-by-step explanation:
180° = (3x - 6) + (8x + 4) + 50° because all interior angles of a triangle add up to 180°
180° = 11x +48°
11x = 132°
x = 12
Anthony has sold 1 1/5 of a box full of Boy Scout cookies for his troop. His sister Anna has sold 9/10 of a box full of Girl Scout cookies. Who has sold more cookies?

Question 1 (1 point) Two points on a line are M(4.5) and N(-2,9). Which ratio represents the slope of the line? О а Ob CON -11-13 oc 7
Answer:
The slope of the line is [tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
Slope:
When we have two points on a line, the slope is given by the change in y divided by the change in x.
Two points on a line are M(4,5) and N(-2,9).
Change in y: 9 - 5 = 4
Change in x: -2 - 4 = -6
The slope is:
[tex]m = \frac{4}{-6} = -\frac{2}{3}[/tex]
The slope of the line is [tex]-\frac{2}{3}[/tex]

What is m KJL? ( thank you for anyone who answers!!)
Answer:
54 degrees. The triangle is isosceles, so 180-72= 108.
108/2=54
The solution is, m KJL=54 degrees.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
from the given figure, we get,
The triangle is isosceles,
so 180-72= 108.
and, we know,
∠J=∠L
So,
108/2=54
Hence, The solution is, m KJL=54 degrees.

Answer is:
a= 90-70
=20
Answer:
The missing angle is 20°
Step-by-step explanation:
The square by the vertex indicates that this is a right angle. A right angle measures 90°. So what you can do is subtract the 70° from the 90°, to get 20°.

identify the slope and y-intercept.
y = - 5
Answer:
The Slope is 0, the y-intercept is -5
Step-by-step explanation
Remember the formula
y = mx + b
m = slope
b = y-intercept
In this situation
y = 0x - 5
m = 0
b = -5
Mike runs a total of 10 miles in 4 days. If he continues running at this rate, how far will he have run in 10 days? solution only need to input the number.
Answer:
25 miles
