HELP PLEASE ! asap. i have a 30% in geometry & really tryna pass before summer .
Answer:
100cm^2 is what it means
Answer:
156 cm²
Step-by-step explanation:
The area of a parallelogram is found by finding the product of its base and perpendicular height. Here, the base is 12cm and the perpendicular height is 13cm.
12cm x 13cm = 156 cm²

identify an equation in point slope form for the line perpendicular to y=-2x+8 that passes through (-3,9)
Answer:
y - 9 = 1/2(x + 3)
Step-by-step explanation:
find the slope that is perpendicular to line y = -2x + 8, which is the negative reciprocal slope: 1/2
substitute the new slope 1/2 and the given/known point (-3, 9) into the point-slope form:
=> y - 9 = 1/2(x - (-3)) => y - 9 = 1/2(x + 3)
point-slope form:

A. 93
B. 57
C. 132
D. 123
Answer:
B
Step-by-step explanation:
The interior angles of a triangle always add up to 180 degrees.
We have two angles already and they add up to 60+63=123 degrees
180-123=57
so the remaining angle is 57 degrees
9514 1404 393
Answer:
D. 123°
Step-by-step explanation:
The external angle is equal to the sum of the remote internal angles.
m∠1 = 60° +63°
m∠1 = 123°

Answer:
G: 1 3/4
Step-by-step explanation:
you have to divide, 8 3/4 cups by 5 and you get 1 3/4!
Answer:
G. 1 3/4
Step-by-step explanation:
There are multiple ways you can do this, but there's one easy way.
You can convert 8 3/4 to a decimal, which is 8.75.
From there, divide 8.75 by 5 and you get 1.75, which is 1 3/4/
Braelyn is writing an equation to represent the perimeter of a rectangle with the width equal to half the length. She knows that the perimeter is equal to 18 units and needs to find the length and width of the rectangle. Which equations represent this relationship? Select the four correct answers.
x + one-half x = 18
2 x + x = 18
2 (x) + 2 (2 x) = 18
x + one-half x + x + one-half x = 18
2 (x + one-half x) = 18
2 x + one-half x = 18

Consider the line - 5x – 3y = 7.
(a) What is the slope of a line parallel to this line?
(b) What is the slope of a line perpendicular to this line?
Answer:
a: m=5/3
b: m=-3/5
Step-by-step explanation:
first, before answering the questions, let's change the line from standard form (ax+by=c), where a and b are free coefficients into slope-intercept form (y=mx+b), where m is the slope and b is the y intercept
subtract 5x from both sides
-3y=-5x+7
divide by -3
y=5/3x-7/3
now to answer part a:
parallel lines have the same slopes, but different y intercepts.
the slope of the given line is 5/3, so therefore, a parallel line to the line y=5/3x-7/3 will also be 5/3
part b:
perpendicular lines have slopes that are negative and reciprocal; if you multiply them together, the result is -1
so to find the slope of a perpendicular line, use this formula:
5/3m=-1
multiply by 3/5 to isolate the variable
m=-3/5
therefore the slope of a perpendicular line will be -3/5
hope this helps!

Then the fraction that come by car is ...
car/total = ...
15/50 = 30/100 = 30%
Please help me on this for my quiz: Which equation represents an inverse variation with a constant of 56?
A: y/x=56
B: 7/y=8/x
C: 1/4y=14x
D:xy/2=28
Answer:
D) xy/2 = 28
Step-by-step explanation:
Inverse Variation:
y = k/x
Given:
k = 56
Work:
y = k/x
y = 56/x
xy = 56
xy/2 = 28
xy = 28 * 2
xy = 56
Explain the difference between parallel and perpendicular slope in fewer than twenty words.
Answer:
parallel refers to two equidistant lines, Because the lines are equally distant, they have the same slope and the angle between them is zero. On the other hand, when two lines intersect at a right angle, they are called perpendicular.

Write your answer in the space below.
B. Who had a greater range of hours spent at rehearsal?
Write your answer in the space below.
Answer:
6 hours. To find the range you arrange the numbers in order from least to greatest, then subtract the largest number in the data set from the smallest.4 hours.b. Troy had the greater range because 6 hours is longer than 4 hours.

Is there a relationship between the percent of high school graduates in each state who took the SAT and the state’s mean SAT Math score? Here is a residual plot from a linear regression analysis that used data from all 50 states in a recent year
A residual plot shows “Percent of high school graduates taking the SAT” along the horizontal axis ranging from 0 to 90 in increments of 10 and “Residual” along the vertical axis ranging from negative 50 to 50 in increments of 25. A horizontal line is drawn at 0 on the vertical axis across the graph. Dots are scattered on the either side of the line across the graph and between negative 30 and 35 on the vertical axis. A dot is shown before 20 on the horizontal axis between negative 70 on the vertical axis.
Explain how the residual plot shows that the Linear condition for performing inference about the slope is, or is not, met.
The variability of the residuals in the vertical direction is roughly the same from the smallest to the largest -value, which suggests that the relationship between mean SAT score and percent taking is not linear.
There is clear curvature in the residual plot, which confirms that the relationship between mean SAT score and percent taking is linear.
There is clear curvature in the residual plot, which suggests that the relationship between mean SAT score and percent taking is not linear.
There is clear curvature in the residual plot, which suggests that the relationship between mean SAT score and residual values is not linear.

Answer:
There is clear curvature in the residual plot, which suggests that the relationship between mean SAT score and percent taking is not linear.
