Find the area of the figure.
Answer:
64 + 28 = 92
Step-by-step explanation:
Split the figure in half creating two triangles and a square.
length and width for the square would be 8ft and 8ft. Multiply both for 64 to be the area.
7ft and 4ft are the height and base for the triangles.
In this case, just multiple 7 and 4 because normally you would need to divide the product by 2 however since there are two triangles it negates the step.
Answer:
92ft^2
Step-by-step explanation:
you have to find the are of the triangle and subtract it from the area of the rectangle.
area of the triangle is 28ft^2
area of the rectangle is 120ft^2
120-28 = 92

y
∝

x
If
y
=
56
when
x
=
49
find,
x
when
y
=
72
Answer:
x = 81
Step-by-step explanation:
y = k√x
56 = k√49
56 = k(7)
Divide both sides by 7
8 = k
k = 8
------------------------
When y = 72
72 = 8√x
Divide both sides by 8
9 = √x
Square both sides
81 = x
x = 81

in a math class with 30 students, a test was given the same day that an assignment was due. There were 21 students who passed the test and 20 students who completed the assignment. There were 7 students who failed the test and also did not complete the assignment. What is the probability that a student completed the homework given that they passed the test?
please help
This approximates to roughly 6/7 = 0.8571
========================================================
Explanation:
Let's define the following
A = number of people who passed the test, and did the hwB = number of people who passed the test, but didn't do the hwC = number of people who failed the test, but did the hwD = number of people who failed the test, and didn't do the hwThere are 30 students in the class total. This must mean A+B+C+D = 30.
We know that "There were 7 students who failed the test and also did not complete the assignment", meaning we can say D = 7.
We can also say A+B = 21 because this is the entire group of people who passed the test (whether they did the hw or not).
This means:
A+B+C+D = 30
(A+B)+C+D = 30
(21) + C + 7 = 30
C+28 = 30
C = 30-28
C = 2
We have 2 people who failed the test, but did the hw.
Because 20 students did the hw, we know that
A+C = 20
A+2 = 20
A = 20-2
A = 18
We have 18 students who passed the test and did the hw. This is out of 21 students who passed. From here on out, we only focus on this group of students because of the phrasing "given that they passed the test". This means we know 100% that whoever we picked, they passed the test.
The probability we're after is therefore:
18/21 = (3*6)/(3*7) = 6/7

Use point-slope form to find the equation of the line with a slope of -3 that passes through the point (-1,0)? Express your answer in slope-intercept form.
Answer:
y = -3x - 3
Step-by-step explanation:
y = -3x + b
0 = -3(-1) + b
0 = 3 + b
-3 = b
y = -3x - 3
In the right triangle below b = 18 and c = 20, solve for a in simplified radical form.
Answer:
a = 2 radical 19
Step-by-step explanation:
a^2 + 18^2 = 20^2
a^2 + 324 = 400
subtract 324 from both sides
a^2 = 76
square root both sides
a = radical 76
simplify radical to get 2 radical 19

[tex] SA= \frac{2}{3} \pi rl+16 \pi r^2[/tex]
Step-by-step explanation:
Surface area of the original cone
[tex] SA= \pi r l + \pi r^2... (1)[/tex]
When, radius is quadrupled and slant height is reduced to one sixth
[tex] i. e. \: \:r = 4r\: \: \&\:\: l= \frac{1}{6}l[/tex]
Plug the above values of r and [tex] l[/tex] in equation (1), new surface area becomes:
[tex] SA= \pi (4r)\times \frac{1}{6} l+ \pi (4r)^2[/tex]
[tex] SA= \frac{4}{6} \pi rl+16 \pi r^2[/tex]

If the radius of a circle is 1 kilometer what is the area of the circle?
Answer:
The area of the circle is [tex]1\pi[/tex] or approximately 3.14 [tex]km^2[/tex]
Step-by-step explanation:
The formula to find the area of a circle is [tex]\pi r^2[/tex], where [tex]r[/tex] represents the radius of the circle. In this case, the area would be [tex]1^2*\pi[/tex] = [tex]\pi[/tex] ≈ 3.14 [tex]km^2[/tex].
Direction: Choose the letter of the correct answer and encircle the letter that corresponds to it.

A nutritionist collects data from 25 popular breakfast cereals. For each cereal, the number of calories per serving is
plotted on the x-axis against the number of milligrams of sodium on the y-axis. The value of , for the resulting
scatterplot is 0.83.
How would the value of the correlation coefficient change if sodium was plotted on the x-axis
and calories plotted on the y-axis?
A.The value of r would increase
B.The value of r would not change
C.The value of r would change to -0 83.
D.The value of r could increase or decrease, depending of the strength of the new relationship.
Answer:
B) The value of r would not change
Step-by-step explanation:
If there's a positive association between sodium and calories, that's like saying there's a positive association between calories and sodium. Therefore, the value of r would not change because both variables are still increasing with each other.

Answer:
85 degrees
Step-by-step explanation:
Hi there!
<x is an exterior of the triangle ABC. An exterior angle of a triangle is equal to the sum of the two opposite interior angles. Therefore, we could say that x is equal to the sum of 60 and 25:
60+25=x
85=x
Therefore, angle x measures 85 degrees.

Write an equation to represent function A
Answer:
y = 312x + 2
Step-by-step explanation:
According to y = mx + b, m stands for slope and b stands for y-intercept. Let us find the y-intercept. To find the y-intercept, the x should be zero in (x, y).
(x, y)
(0, 2) ---> y-intercept (b)
Now that we have found the y-intercept, we will now find the slope by using its formula.
Slope formula:-
m = y2 - y1 / x2 - x1
Pick two random (x, y). I will pick the first and last pairs.
(0, 2) and (4, 1250)
Now plug these two pairs in the formula.
m = y2 - y1 / x2 - x1
m = 1250 - 2 / 4 - 0
m = 1248 / 4
m = 312
This means that the slope (m) is 312. Now put that in y = mx + b form.
y = mx + b
y = 312x + 2
Both of the forms are the same. Hope this helps, thank you :) !!
