In the diagram below, m_MON = 1249, m _ MOP = 2x + 1, and m2 NOP = 2x
+1. What are the exact measures of the angles?
N
A. m2 MOP= 62
m2 NOP = 62
B. m2 MOP = 61
m 2 NOP = 61
C. m MOP = 48
m2 NOP = 72
D. m2 MOP = 122
m 2 NOP = 122
Answer:
The answer is below
Step-by-step explanation:
The Angle Addition Postulate states that the measure of an angle formed by two or more angles which are placed side by side is the sum of the measures of the two angles.
Therefore:
∠MON = ∠MOP + ∠NOP (angle addition postulate)
Substituting values gives:
124 = (2x + 1) + (2x + 1)
124 = 2x + 2x + 1 + 1
124 = 4x + 2
subtracting 2 from both sides of the equation:
124 - 2 = 4x + 2 - 2
4x = 122
Dividing through by 4:
4x / 4 = 122 / 4
x = 30.5
Therefore ∠MOP = 2x + 1 = 2(30.5) + 1 = 62°, ∠NOP = 2x + 1 = 2(30.5) + 1 = 62°
∠MOP = 62°, ∠NOP = 62°
How can I solve?
Solve for x (hint - use the quadratic formula)
An unconditional acceptance into a graduate program at a university will be given to students whose GMAT score plus 100 times the undergraduate grade point average is at least 1075. Robbin's GMAT score was 800. What must her grade point average be in order to be unconditionally accepted into the program?
Robbin's grade point average must be at least ___ in order to be unconditionally accepted into the program.
Answer:
Robbin's grade point average must be at least 2.75 in order to be unconditionally accepted into the program.
Step-by-step explanation:
An unconditional acceptance into a graduate program at a university will be given to students whose GMAT score plus 100 times the undergraduate grade point average is at least 1075.
This means that:
[tex]x + 100y \geq 1075[/tex]
In which x is the GMAT score and y is the GPA.
Robbin's GMAT score was 800.
This means that [tex]x = 800[/tex]
What must her grade point average be in order to be unconditionally accepted into the program?
We have to solve the inequality for y. So
[tex]x + 100y \geq 1075[/tex]
[tex]800 + 100y \geq 1075[/tex]
[tex]100y \geq 275[/tex]
[tex]y \geq \frac{275}{100}[/tex]
[tex]y \geq 2.75[/tex]
Robbin's grade point average must be at least 2.75 in order to be unconditionally accepted into the program.

Find the surface area of this rectangular prism. Be sure to include the correct unit in your answer.
Answer:
190 ft^2
Step-by-step explanation:
So first we need to find which equation we're using and since it's a rectangular prism we're going to use:
2Lw + 2wh + 2Lh
Now what we need to do is plug in the values
2*9*2 + 2*2*7 + 2*9*7
Now just multiply everything and then add it together.
36 + 28 + 126
Once you add everything together you get:
190
The question says to include the correct unit. It says that its feet, but we need to know if its feet squared (^2) or cubed (^3)
If it were area of the whole object, it would be cubed because it is all the area that the object takes up but since it's just the area of the surface it's going to be squared. Therefore, the answer is:
190 ft^2

Give the values of A, B, and C needed to write the equation's general form.
(5 + x)(5 - x) = 7
1. A = 1; B = 0; C = -18
2. A= -1; B = 0; C = 25
3. A = 25; B = 0; C = -1
Given:
The equation is:
[tex](5+x)(5-x)=7[/tex]
To find:
The value of A, B and C for the equation's general form.
Solution:
We have,
[tex](5+x)(5-x)=7[/tex]
Using distribution property, we get
[tex](5)(5)+(5)(-x)+(x)(5)+(x)(-x)=7[/tex]
[tex]25-5x+5x-x^2=7[/tex]

Answer:
$80
Step-by-step explanation:
You are given the formula ...
P = I/(rt)
and the values I = 20, r = 0.05, t = 5.
Put the numbers in place of the corresponding variables and do the arithmetic.
P = 20/(0.05·5) = 20/0.25 = 80
The amount $80 will generate $20 in interest over 5 years at 5% per year.

Answer:
Answer: Composite figure: 360 ft3
Explanation:
The volume of the triangular prism:
The base area of the prism = 1/2 x 4 x 6 = 12 ft2
Height = 6 ft
The volume of the triangular prism = 12 x 6 = 72 ft3
The volume of the rectangular prism:
The base area of the prism = 4 x 6 = 24 ft2
Height = 12 ft
The volume of the triangular prism = 12 x 24 = 288 ft3
Volume of the composite figure = (288 + 72)ft3 = 360 ft3

What is the slope of a line perpendicular to the line y=2x+5 ?What is the slope of a line perpendicular to the line y=2x+5 ?
1/2
−2
2
−1/2
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
Hi there!
In the given equation [tex]y=2x+5[/tex], the slope of the line is 2.
Perpendicular lines always have slopes that are negative reciprocals, like negative "flipped" fractions.
Example: The negative reciprocal of [tex]\frac{3}{1}[/tex] (which is the same as 3) is [tex]-\frac{1}{3}[/tex].
Example 2: The negative reciprocal of [tex]-\frac{4}{3}[/tex] is [tex]\frac{3}{4}[/tex].
Using this logic, the negative reciprocal of 2, or [tex]\frac{2}{1}[/tex], is [tex]-\frac{1}{2}[/tex]. Therefore, the slope of a line perpendicular to the line [tex]y=2x+5[/tex] is [tex]-\frac{1}{2}[/tex].

Marcus drew a circle on his coordinate plane at (4,3) in which quadrant of the coordinate plane did Marcus draw in the circle?
Answer:
It should be in quadrant 1
Step-by-step explanation:
The quadrants of a coordinate plane can be counted counter-clockwise starting from quadrant 1, if you know the exact point you're trying to find, you can use the x and y to figure out which quadrant it's in.
If the x and y values are both positive, the point is in quadrant 1.
If the x value is negative and the y value is positive, the point is in quadrant 2.
If the x and y values are both negative, the point is in quadrant 3.
If the x value is positive and the y value is negative, the point is in quadrant 4.

Answer:
y(x(t)) = -4t^2 -8t -5
Step-by-step explanation:

y(x(t)) = -4t^2 -8t -5
decide whether each expression is equal to 6 x 3/4. Write an X in the table to respond.
Answer:
6 × ¼ is NOT EQUAL TO 6 × ¾
8 × ²/4 is NOT EQUAL TO 6 × ¾
18/(2 × 2) is EQUAL TO 6 × ¾
Step-by-step explanation:
Given 6 * ¾,
We're asked to determine if each of the given expressions is equal or not equal to 6 * ¾.
Let's evaluate 6 * ¾
6 × ¾ = (6×3)/4 = 18/4 = 4.5
Now, let's compare each expression given to determine if it is equal or not
✔️6 × ¼ = (6×1)/4 = 6/4 = 1.5
Therefore,
6 × ¼ is NOT EQUAL TO 6 × ¾
✔️8 × ²/4 = (8×2)/4 = 16/4 = 4
Therefore,
8 × ²/4 is NOT EQUAL TO 6 × ¾
✔️18/(2 × 2) = 18/4 = 4.5
Therefore,
18/(2 × 2) is EQUAL TO 6 × ¾
A sample of 26 elements from a normally distributed population is selected. The sample mean is 10 with a standard deviation of 4. The 95% confidence interval for μ is _____. a. 6.000 to 14.000 b. 8.384 to 11.616 c. 8.462 to 11.538 d. 9.846 to 10.154
Answer:
B. 8.384 to 11.616
Step-by-step explanation:
We have
mean = 10
s = 4
n = 26
the degrees of freedom = n-1
= 26 - 1 = 25
α = 1-95%
= 1 - 0.95
= 0.05
α/2 = 0.05/2 = 0.025
using the t table
t0.025, 25 = 2.06
we find the margin of error
t * s/√n
= 2.06 * 4/√26
= 1.616
10-1.616 < μ < 10+1.616
= 8.384<μ<11.616
therefore option b is the right solution
