Answer:
3x=20
Step-by-step explanation:
Perimeter is just all the sides of a shape added. So, x+x+x=20 or, more simply put, 3x=20.

1/2 servings are in a box of oatmeal that contains6 3/4 cups of oatmeal.
Answer: B) 13 & 1/2
========================================================
Explanation:
There are a few ways to approach this problem. It might be easiest to convert all the fractions to decimal form
1/2 = 0.5
3/4 = 0.75
6 & 3/4 = 6 + 3/4 = 6 + 0.75 = 6.75
The problem is rephrased as: "How many 0.5 cup servings in a box of oatmeal that contains 6.75 cups of oatmeal?"
To find out, we divide the two values (large over small) to get 6.75/0.5 = 13.5
Then convert back to a mixed number:
13.5 = 13 + 0.5 = 13 + 1/2 = 13 & 1/2
--------------------
Side note: The reason why we divide is due to this
x = number of servings
0.5x = total number of cups = 6.75
So we're effectively solving the equation 0.5x = 6.75, in which we divide both sides by 0.5

Given |u| = 10 at ∠135° and |v| = 5 at ∠30°, what expression can be used to find |u + v|?
(10)2 + (5)2 – 2(10)(5) cos(45°)
(10)2 + (5)2 – 2(10)(5) cos(75°)
(10)2 + (5)2 – 2(10)(5) cos(105°)
(10)2 + (5)2 – 2(10)(5) cos(165°)
Answer:
B, [tex]10^{2} + 5^{2}- 2(10)(5)cos(75)[/tex]
Step-by-step explanation:
Using the law of cosines, which is [tex]c^{2}=a^{2}+b^{2}-2ab cos(C)[/tex], you can simply insert all the values.
c=|u+v|
a= r value of u (10)
b= r value of v (5)
To find C, you simply have to subtract v from u, and then subtract that number from 180 to find the reference angle.
I.E.: ∠135 - ∠30 = ∠105 ↔ 180 - 105 = 75 = C
so, the completed equation would be 10^{2} + 5^{2}- 2(10)(5)cos(75)

Question 12 The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of and a standard deviation of . Find the probability that the mean GPA of a random sample of students selected from this university is or higher.
Complete question :
The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of 3.02 and a standard deviation of .29.Find the probability that the mean GPA of a random sample of 20 students selected from this university is 3.10 or higher.
Answer:
0.10868
Step-by-step explanation:
Given that :
Mean (m) = 3.02
Standard deviation (s) = 0.29
Sample size (n) = 20
Probability of 3.10 GPA or higher
P(x ≥ 3.10)
Applying the relation to obtain the standardized score (Z) :
Z = (x - m) / s /√n
Z = (3.10 - 3.02) / 0.29 / √20
Z = 0.08 / 0.0648459
Z = 1.2336940
p(Z ≥ 1.2336) = 0.10868 ( Z probability calculator)

[tex]\Large\boxed{\tt Answer: Angle ~CDE}[/tex]
[tex]\tt Step-by-step~explanation:[/tex]
Since the sum of the interior angles of a triangle is always 180º, we know that ∠CED and ∠ECD are less than 87º altogether. This is because 93º + 87º = 180º. 87º is already less than 90º, so we know that ∠CDE is the largest angle of this triangle.

Conclusion:
-a-1 will be positive.Step-by-step explanation:
Checking -a - 1
From the given line number, we can determine that
The value of a will be negative because it is located on the left side of the origin 0.
i.e. value of a > -2
so
-a - 1 will be positive because if we put the value a = -1.5 let say
then
-a - 1 = -(-1.5) - 1 = 1.5 -1 = 0.5
Therefore, -a-1 will be positive.
Checking -b + 2
As b > 2
putting b = 2.1 (taking the value of b slighly above than 2)
-b+2 = -2.1+2 = -0.1
Therefore, -b + 2 will be negative.
Conclusion:
-a-1 will be positive.Choose Yes or No to tell if the number 102 will make each equation true.

Which Sentence about measuring angles is true?
A. An angle that turns through 10/360 of a circle has a measure of 36°
B. An angle that through 1/12 of a circle has a measure of 1°.
C. An Angle that turns through 10/360 Of a circle has a measure 10°
D. An angle that turns through 1/12 Of a circle has a measure of 12°

The statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]10^{o}[/tex]" is true.
Angle
When two straight lines or rays intersect at a shared terminal, an angle is generated. The angle can be measured in degrees or radians.
How to find a true statement about measuring the angle from the given statements?Let us discuss all four options.
The measure of a whole circle is [tex]360^{o}[/tex]
(A) Here, [tex]\frac{10}{360}\times360=10^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]36^{o}[/tex]" is false.
(B) Here, [tex]\frac{1}{12}\times360=30^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{1}{12}[/tex] of a circle has a measure of [tex]1^{o}[/tex]" is false.
(C) Here, [tex]\frac{10}{360}\times360=10^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]10^{o}[/tex]" is true.
(D) Here, [tex]\frac{1}{12}\times360=30^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{1}{12}[/tex] of a circle has a measure of [tex]12^{o}[/tex]" is false.
Therefore, option (C) is correct.
Hence, the statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]10^{o}[/tex]" is true.

Consider two lines having the following equation:
12y-6x=12 line 1
8y+4x=16 line 2
Answer:
x = 1 and y = 1.5
Step-by-step explanation:
Given that,
12y-6x=12 ..... 1
8y+4x=16 ...... 2
Equation (1) can be written as :
2y-x = 2 ... (3)
Equation (2) can be written as :
2y + x = 4 .... (4)
Adding equation (3) and (4)
2y-x + 2y + x = 2 + 4
4y = 6
y = 1.5
Put y = 1.5 in equation (3).
2(1.5)-x = 2
3-x=2
x =1
Hence, the solution of the above equations are (1,1.5).
