Answer:
A) 11.3°
Step-by-step explanation:
got it right on edge :)
The measure of the angle between the vectors will be 11.3°. Then the correct option is A.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
The angle between the vector is given as,
[tex]\theta = \cos^{-1} \dfrac{u \cdot v}{\left|a \right|\left|b \right|}[/tex]
Given vectors u = (2, -3) and v= (1, -1).
Then the measure of the angle between the vectors will be
[tex]\theta = \cos^{-1} \dfrac{(2, -3)\cdot (1, -1)}{\sqrt{2^2+(-3)^2} \ \sqrt{1^2 + (-1)^2}}\\\theta = \cos^{-1} \dfrac{2 + 3}{\sqrt{13} \sqrt{2}}\\\theta = \cos^{-1} \dfrac{5}{\sqrt{26}}\\[/tex]
θ = 11.3°
Then the correct option is A.

Answer:
y = 62, x = 122
Step-by-step explanation:
Every triangle's sum of interior angles = 180°.
60 + 58 + y = 180
118 + y = 180
y = 62
Supplementary angles are adjacent angles that make up a straight angle (180 degrees)
58 + x = 180
x = 122
Answer:
x = 122°, y = 62°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 to find y
y = 180° - (60 + 58)° = 180° - 118° = 62°
x and 58° are adjacent angles and are supplementary, thus
x = 180° - 58° = 122°
Because Kendall's business spent more money than it collected, the business's balance sheet showed a balance of -$1,280$ at the end of the month. The next day, Kendall's business spent $560 on new tools. Part A Kendall determines that the new balance is -$720 because 1,280 + 560 = -720 . Did Kendall correctly determine the new balance? Explain why or why not. If not, calculate the new balance. Respond in the space provided.
Answer: No. Kendall did not correctly determine the new balance. The new balance is -$1840.
Step-by-step explanation:
From the question, we are informed that Kendall's business spent more money than it collected, and therefore the business's balance sheet showed a balance of -$1,280 at the end of the month. We are informed that the next day, Kendall's business spent $560 on new tools.
Therefore, since Kendall made a purchase, this is an expense and we have to subtract it from the previous balance. This will be:
= -$1280 - $560
= - $1840
The new balance is -$1840
Answer:
She is not correct. The correct answer should be -$1840
Step-by-step explanation:
Explanation: Kendal is ultimately wrong, because in his step in adding the $560 spent on new tools, she had added a positive number, which meant they deposited money to go out of debt. Instead he was supposed to subtract the $560, or even add -$560 to the businesses balance. If calculated correctly, by subtracting $560 to the current balance, it would get us to -$1840.

Two of the vertices of a rectangle are (6,1) and (7,1) . IF the rectangle has a perimeter of 18 units, then what are the coordinates of its other two vertices
Answer:
(6 , -9) (7, -9)
Or
(6, 11) (7, 11)
Step-by-step explanation:
Given: Two of the vertices of a rectangle are (6,1) and (7,1)
Perimeter= 18 units
To get the value of "x"
The distance between Two point can be calculated as (6-7)=-1
Then x= -1
We can get the value of "y" by using expression for perimeter,
The perimeter P= 2x+2y=18
= 2(-1)+2y= 18
-2+2y=18
2y=18+2
2y= 20
y=10
The "y" coordinate can move up or can move down
y1=( 1-10)=-9
Or
y2=( 1+10)=11
Hence, the two other points are;
(6 , -9) (7, -9)
Or
(6, 11) (7, 11)
150 is 96% of what number TWT
Answer:
156.25
Step-by-step explanation:
150 ÷ 96%
= 156.25
Answer (Three Different Forms):
Decimal:
156.25
Fraction:
[tex]\frac{625}{4}[/tex]
Mixed Number:
[tex]156\frac{1}{4}[/tex]
Step-by-step explanation:
96% is the same as 0.96, and so this problem can be written algebrically as:
0.96 ⋅ x = 150
Solve for x by dividing both sides of the equation by 0.96 to isolate the variable:
x = [tex]\frac{150}{0.96}[/tex]
Divide/simplify [tex]\frac{150}{0.96}[/tex] to get the following three options (you can choose which one to use):

Mark is in charge of the fundraiser for his church. He is selling pre-sale tickets for $10 and at-the-door tickets for $13. The venue has the capacity to hold 275 people. The graph represents the number of raffle tickets he needs to sell to offset the upfront costs and raise at least $3,100:
Graph with x axis labeled pre sale tickets and y axis labeled at the door tickets. There are two lines intersecting at one hundred fifty eight and three hundred thirty three thousandths and one hundred sixteen and six hundred sixty seven thousandths.
What is the minimum number of at-the-door tickets he needs to sell to make his goal?
159
158
117
116
Answer:
The answer to the question above is he needs a minimum of 117 tickets to reach his goal
Step-by-step explanation:
This is true because of the at-the-door tickets it shows on graph 116.667, and in order to find the minimum amount we need to round, and in this case round up, thus when we round we are left with 117, therefore providing you with your answer 117.

7x-4x=11-2 ---> combine like terms
3x=9 ---> divide by 3
x=3
Answer:
x = 3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
7x + 2 = 4x + 11
Step 2: Solve for x
Subtract 4x on both sides: 3x + 2 = 11Subtract 2 on both sides: 3x = 9Divide 3 on both sides: x = 3Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 7(3) + 2 = 4(3) + 11Multiply: 21 + 2 = 12 + 11Add: 23 = 23Here we see that 23 does indeed equal 23.
∴ x = 3 is the solution to the equation.

When a 40-foot pole casts a shadow of
30 feet, how tall is a nearby tree that
casts a shadow of 15 feet?
Set up a ratio with height over shadow height:
40/30 = x/15
Cross multiply:
40 x 15 = 30x
600 = 30x
Divide both sides by 30:
X = 20
The tree is 20 feet tall.
Answer:
20
Step-by-step explanation:
It tells you that a 40 foot pole casts a 30 foot then it asks you how tall is a tree if it casts a 15 foot shadow. We see that 30 is exactly 2 times 15
30 = 2 * 15
So we simply do that to 40 too.
40 / 2 = 20
So 20 is our answer.

if an angle is acute then it measures 20 degrees which of the following would be a counterexample? 48 degrees, 90 degrees, 105 degrees, or 180 degrees
The counterexample can be the angle can be 105 degrees.
What is counter example statement?A counterexample is an example in which the hypothesis is true, but the conclusion is false. If you can find a counterexample to a conditional statement, then that conditional statement is false.
However, showing that a mathematical statement is false only requires finding one example where the statement isn't true. Such an example is called a counterexample because it's an example that counters, or goes against, the statement's conclusion.
Given statement:
if an angle is acute then it measures 20 degrees
As, we know counterexample is an example in which the hypothesis is true, but the conclusion is false.
Also, acute angles measure less than 90 degrees.
Thus, the counter example will be if an angle is acute then it measures 105 degrees

Answer:
C = 4x+ 16
Step-by-step explanation:
We know that When two parallel lines are cut by a third line, the third line is called the transversal, forming 8 angles.
From the attached diagram,
∠E and (2x+8) are vertical angles formed by the transversal line.
We know that vertical angles are equal.
Hence,
∠E = (2x+8)
∠A and ∠E are called the corresponding girls.
as
∠E = (2x+8)
so
∠A = ∠E = (2x+8)
Therefore,
C = m∠A + m∠E
C = 2x+8 + 2x+8
C = 4x+ 16
Therefore,
C = 4x+ 16
