Answer:
C
Step-by-step explanation:
We want the equation of the line that passes through (3, 6) and is perpendicular to:
[tex]3x-4y=-2[/tex]
First, convert the second equation into slope-intercept form:
[tex]-4y=-3x-2\Rightarrow \displaystyle y=\frac{3}{4}x+\frac{1}{2}[/tex]
So, we can see that the slope of the line is 3/4.
The slopes of perpendicular lines are negative reciprocals of each other.
Therefore, the slope of the new line is -4/3.
It passes through the point (3, 6).
We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]\displaystyle y-(6)=-\frac{4}{3}(x-3)[/tex]
Distribute:
[tex]\displaystyle y-6=-\frac{4}{3}x+4[/tex]
Therefore:
[tex]\displaystyle y=-\frac{4}{3}x+10[/tex]
The answer is C.
2x+2y=18
x=3-y

Step-by-step explanation:
I have a spinner that is divided into 4 equal sections colored red, blue, green, and yellow .If I spin the spinner twice ,What is the probability that the spinner will land on yellow both times ?
Answer:
is of 25%
Step-by-step explanation:
The probability that the spinner will land on yellow both times is 1/16.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, A spinner is divided into 4 equal sections colored red, blue, and green.
So, N(S) = 4 and N(R) = 1, N(B) = 1, N(G) = 1 and N(Y) = 1.
Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.
As the events of getting yellow both times is independent,
The likelihood that the spinner will hit yellow twice is,
P(Y, Y) = P(Y)×P(Y).
P(Y, Y) = (1/4)×(1/4).
P(Y, Y) = 1/16.

Answer:
I believe the measurement of angle 5, would be 114.
Step-by-step explanation:
We can solve this by using alternate interior angles. First we must find the other alternate interior angle for angle 5. To do this we take 66 and subtract it from 180. We now find that the angle adjacent to the angle measuring 66 degrees is equal to 114 degrees. Now, the angle we just found the measurements for, is the alternate interior angle for angle 5. Therefore, since they are alternate interior angles, angle 5 is equal to 114 degrees.

please help with an explanation.
Answer & Step-by-step explanation:
Let's have
C = Creepers
B = Balloons
1) 6C + 20B = 11.9
2) 2C + 15B = 6.05
Eliminate
16C + 20B = 11.9 x3
-2C + 15B = 6.05 x4
18C + 60B = 35.7
-8C + 60B = 24.2
10C/10 = 11.5/10
C = 1.15
1/3y y = 15
please help
Answer:
Step-by-step explanation:
y in (-oo:+oo)
(1/3)*y = 15 // - 15
(1/3)*y-15 = 0
1/3*y-15 = 0 // + 15
1/3*y = 15 // : 1/3
y = 15/1/3
y = 45
y = 45
Answer: The answer is five
Step-by-step explanation: This is because if the equasion is 1/3 x y and y=15 than the equasion is 1/3 x 15 or 1/3 x 15/1 which is 5
A quadrilateral has two angles that measure 240° and 70°. The other two angles are in a ratio of 2:3. What are the measures of those two angles?
Answer:
The two missing angles are 20 and 30 degrees.
Step-by-step explanation:
Quadrilaterals have four interior angles that add up to 360 degrees.
So we have two angles that are 240 degrees and 70 degrees.
If 240 + 70 = 310
That means the other two angles added together must be equal 50.
Because 360 - 310 = 50
So their ratio is 2:3 which means they have five equal parts.
Which would mean 50/5 = 10
2 x 10 = 20
3 x 10 =30
This means the missing angles are 20 and 30 degrees.

Determine how (if possible) the triangle can be proven similar:
Answer:
Not similar
Step-by-step explanation:
You can only find the vertical angles at the intersection.
So, you know they share one angle.
That is not enough information to prove similarity.
Therefore, I'd say they're not similar.

You will need to use the expressions for the angles given below.
A) 2(x + 15) B) 3x+10 C) 5x
(a) Identify the angle relationship and setup your equation with the given expressions.
(b) What is the value of x? Show your work.
(c) What is the measure of angle A, B, & C? Show your work and make sure to identify which is which.
Answer:
I only know B and C
Step-by-step explanation:
Part B)
2 (x+15) + 3x + 10+ 5x = 180 2x + 30 + 3x + 10 +5x = 180 10 +40 = 180
- 40 -40 10x divided by 10 = 140 divided by 10 x= 14
Part C)
A = 2 (x + 15) = 2 (14 + 15) = 2 * 29 = 58 degrees
< B = 3 x + 10 = 3 * 14 + 10 = 52 degrees
< C = 5 x = 5 * 14 = 70 degrees

Chris bought 2 chicken sandwiches and 3 bowls of vegetable soup for $16.50. Jim bought 1 chicken sandwich and 2 bowls of vegetable soup for $9.50. What was the cost of a bowl of soup? A) $4.50 B) $2.50 C) $5.50 D) $3.25
Answer:
Step-by-step explanation:
This is a system of equations, best solved by using the elimination method. But first we have to come up with our 2 equations that represent the system. Let's call the chicken sandwiches "c" and the bowls of soup "b".
If Chris bought 2 chicken sandwiches and 3 bowls of soup for $16.50, his equation is:
2c + 3b = 16.50
If Jim bought 1 sandwich and 2 bowls of soup for $9.50, then his equation is:
1c + 2b = 9.50
We put these together, one above the other, lining up the variables:
2c + 3b = 16.50
1c + 2b = 9.50
If we multiply the second equation by -2 we can eliminate the c variable. Multiplying the second equation by -2 changes only that equation, making the "new" system:
2c + 3b = 16.50
-2c - 4b = -19.00
When we add straight down each column, the c's cancel each other out (they subtract away) and in the b column we have -1b, and in the answer column, we have -2.50.
That equation is -b = -2.50 or b = 2.50
A bowl of soup costs $2.50, choice B

What is the mode and range of the data set
18,22,20,21,24
Answer:
There is NO mode.
The range is 6.
Step-by-step explanation:
Mode is the most frequent number and in this case there are no repetitive numbers.
Range is the Max Number minus the Minimum Number. So in this case 24-18 which equals 6.
6 is what percent of 9?
Answer:
33 1/3 %
Step-by-step explanation:
6/9 = 1/3 = 33 1/3 %
Hope that helps!
The 6 is approximately 66.67% of 9.
To calculate what percent 6 is of 9, we can use the following formula:
Percent = (Part / Whole) * 100
In this case, 6 is the part and 9 is the whole. Substituting these values into the formula:
Percent = (6 / 9) * 100
To simplify, we divide 6 by 9:
Percent = (2 / 3) * 100
Multiplying 2/3 by 100:
Percent = (2 * 100) / 3
Percent = 200 / 3
To express the result as a decimal:
Percent ≈ 66.67
Therefore, 6 is approximately 66.67% of 9.
