Answer:
∠3 = 102°
Step-by-step explanation:
║A straight line always equals 180°. So all we need to do is subtract 78° ║from 180° for the missing angle.
180 − 78 = 102
∠3 = 102°
Further explanation:
║The image shows two slanted lines across one vertical line. If we visualize ║a circle around the point where the slanted line intercepts with the vertical ║line, we can solve this.
[we only need one line to work with, because both lines are parallel]
║That circle you visualized divides the intercept into four sectors. One of ║those sectors, or angles, is labled 78°. We need to find the angle measure ║underneath the labled sector. The sector in the bottom right corner has ║the same angle measure as the labled sector, which is 78°. The sector ║labled ∠3 has the same angle measure as the sector in the upper right.
[a full rotation around an angle is always 360°]
║This can be easily solved by subtracting 78° from 180° to get the angle ║measure for the upper right sector, which is equivalent to ∠3. Using basic ║subtraction, 180° − 78° = 102°. We can prove this by multiplying 78° by 2, ║multiplying 102° by two, and adding the products.
78 ⋅ 2 = 156
102 ⋅ 2 = 204
204 + 156 = 360
║Because the sums equal 360°, we can determine the answer is true.

On two investments totaling $6,500, Lydia lost 7% on one and earned 8% on the other. If her net annual receipts were $364, how much was each investment?
Answers
Answer:
$3,442.40
$3,057.60
Step-by-step explanation:
The computation of the each investment is as follows:
let us assume the one investment be x
And, the other investment be y
So
According to the question
x + y = $6,500
And,
-7x + 8y = $364
Now multiply by 7 in equation 1
7x + 7y = $45,500
-7x + 8y = $364
15y = $45,864
y = $3,057.60
x = $6,500 - $3,0657.60
= $3,442.40

Yall what is "Mei runs 66.72 miles in 6 weeks.If she runs 2 days each week,what is the average distance she runs each day?"
Answers
Answer:
5.56 miles
Step-by-step explanation:
We are told from the above question:
Mei runs 66.72 miles in 6 weeks.
She runs 2 days each week
Therefore, the total number of days she runs in 6 weeks is calculated as:
1 week = 2 days
6 weeks = x
Cross Multiply
x = 6 weeks × 2 days/1 week = 12 days
The average distance she runs each day is calculated as:
12 days = 66.72 miles
1 day = x
Cross Multiply
12 days × x = 1 day × 66.72 miles
x = 1 day × 66.72 miles/12 days
x = 5.56 miles
The average distance she runs each day is 5.56 miles.

The probability that Felix will spin a green and an F on the next spin is 2/45.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given, Felix spins each spinner 30 times. He
records the number of times each section is spun. Red (7), Yellow (5), Blue (10), Green (8)
Since probability distribution:
A probability distribution is a mathematical function that describes the probability of different possible values of a variable.
probability= desired outcome/ Total Outcomes
In our case,
Total outcomes = 30 *30
Desired outcome = spin a green and an F on the next spin
Since from probability distribution getting F and getting green has a likelihood of 5 and 8.
thus,
Probability = 8 * 5/ 30 *30
probability = 2/45
therefore, the probability that Felix will spin a green and an F on the next spin is 2/45.

Question does not seem complete as it lacks what exactly needs to be done.
I will however assume that it wants the final price of this pair of shoes.
The shoes cost $54.75
A 9% processing fee will be added to the cost:
= 54.75 + ( 1 + 9%)

Then there is a shipping fee of $5.99.
Total is:
= 59.68 + 5.99

In the equation x - 9y = 21, which variable should you isolate?
Answers
this is a slope intercept form equation
if you were to solve it, you’d get y = 1/9x - 7/3
We will isolate the variable y to make the equation in the slope-intercept form.
And the equation is y = x/9 - 7/3.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given:
A linear equation,
x - 9y = 21.
We will isolate the variable y to make the equation in the slope-intercept form.
9y = x - 21

What is the slope of the line that is parallel to the line joining the points (7, -5) and (-5, 7)?
Answers
Answer:
The slope is -1.
Step-by-step explanation:
We want to find the slope of the line that is parallel to the line joining the points (7, -5) and (-5, 7).
First, we can use the slope formula to find the line passing through (7, -5) and (-5, 7). The slope formula is:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute and evaluate:
[tex]\displaystyle m=\frac{(7)-(-5)}{(-5)-(7)}=\frac{12}{-12}=-1[/tex]
So, its slope is -1.
Recall that parallel lines have the same slope.
Therefore, the slope of the line that is parallel to the line joining the points (7, -5) and (-5, 7) will also be -1.

A store sells ink jet printers and laser printers. On Monday, it sold a total of 100 printers. The store earns $40 profit for each ink jet printer sold and $55 profit for each laser printer sold. If the store's profits from printer sales were $4,600 on Monday, how many more ink jet printers were sold than laser printers?
Answers
Answer:
The store sold 20 more ink jet printers than laser printers.
Step-by-step explanation:
Since the store sold 100 printers, you can say that the result of adding up the numbers of each type of printers sold is equal to 100, which is:
x+y=100, where:
x is the number of ink jet printers sold
y is the number of laser printers sold
Also, you know the amount the profit the store gets for each type of printer and the total profit received on Monday which means that adding up the results of multiplying each type of printer for its price is equal to the total profit, which can be expressed as:
40x+55y=4,600
Now, you have two equations:
x+y=100 (1)
40x+55y=4,600 (2)
You have solve this system of equations to find the number of ink jet and laser printers that were sold. First, you have to solve for x in (1):
x=100-y (3)
Then, you have to replace (3) in (2) and solve for y:
40(100-y)+55y=4,600
4000-40y+55y=4,600
15y=600
y=600/15
y=40
Finally, you can replace the value of y in (3) to find the value of x:
x=100-40
x=60
Now that you know that the store sold 60 ink jet printers and 40 laser printers, you can find the difference between this numbers to be able to know how many more ink jet printers were sold:
60-40=20
According to this, the answer is that the store sold 20 more ink jet printers than laser printers.
