What is the value of y in the picture
A. 83
We can see that the Y value is less than 90 degrees or right angle. So we can cross out answer options C and D.
And we should know that all of the triangles add up to 180 degrees.
So the math would do is:
46+51=97
180-97=83
So...
The Y value is 83.

Which deal is better to buy 5.90 buy 3 books get one free book or 6 for 24.96
Answer:
6 for $24.96
Step-by-step explanation:
$5.90 * 3 = $17.70
Therefore 4 books would be $17.70 because you get one for free
$24.96/6 = $4.16
Therefore if you got 4 books it would be $16.64
So, buying 6 books would be cheaper.

Jaxon was asked 40 questions on a test he answered 80% incorrectly how many did he get correct
Answer:
8 correct.
Step-by-step explanation:
80 / 100 = x / 40 (Since he got 80% INCORRECT you will subtract the value of x from 40)
100x = 80 x 40
x = 3200 / 100
x = 32
40 - 32 = 8

Subtract 24 from both sides
x = 81
Simple.
The value of x is 81.
what is exterior angle property?If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles.
Given:
<1 = x
<2 = 24
exterior angle = 105
Now, using exterior angle property
105 = x +24
x= 105 - 24
x= 81
Hence, the value of x is 81

1.Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.
How many miles does the first cyclist bike in 45 minutes?
Answer:
9 miles
Step-by-step explanation:
If 1 hour is 12 miles, then 30 mins is 6 miles, then 15 minutes is 3 miles.
30+15=45
6+3=9
The first cyclist bikes 9 miles in 45 minutes.
Since two cyclists are 7 miles apart when they begin biking away from each other in opposite directions, and the speed of the first cyclist is 12 miles per hour, to determine how many miles does the first cyclist bike in 45 minutes the following calculation must be done:
60 = 12 45 = X 45 x 12/60 = X 540/60 = X 9 = X
Therefore, the first cyclist bikes 9 miles in 45 minutes.

Write the equation of the line, in slope-intercept form, with the following information slope:1/5 point: (20,-5)
Answer:
y = 1/5x - 1.
Step-by-step explanation:
Slope intercept form: y = mx + b
in this equation, the m is the slope (the amount the line moves vertically divided by the amount it moves horizontally from one point to another) and the b is the y-intercept (meaning where the line meets with the y-axis when graphed).
So, m is equal to 1/5 because that is the slope.
Now, to find b (the y-intercept), I am going to plug in the coordinate values of the point (20,-5) into the equation.
The 20 is the x coordinate and the -5 is the y-coordinate because the point is written in (x, y) form.
Here's how it looks with everything plugged in:
-5 = 1/5(20) + b.
The slope-intercept form is y = mx + b, and I just plugged in my values where
y (y-coordinate)= -5
m (slope)= 1/5
x (x-coordinate) = 20
Now that I know everything, I just need to solve for b, the y-intercept:
-5 = 1/5(20) + b.
-5 = 4 + b (simplified)
-1 = b
so, the y-intercept is -1.
Now, in slope-intercept form, the answer is: y = (1/5)x - 1.

Yosemite Falls is the highest waterfall in North America and the fifth highest in the world. When viewed from the valley, it appears to be a single waterfall. However, it actually has three parts. The upper fall has the longest drop of 1430 feet. The middle cascade is 675 feet long, and the lower fall drops another 320 feet. What is the total length that the water falls?
Answer:
The water falls a total length of 2,425 feet
Step-by-step explanation:
In order to calculate the total length of the waterfall, we will find the sum of the three parts of the waterfall.
Length of upper fall = 1430 feet
Length of middle cascade = 675 feet
Length of lowe fall = 320 feet
Total length of fall = (Length of upper fall) + (Length of middle cascade) + (Length of lowe fall)
= 1430 + 675 + 320 = 2,425 feet
Total length that the water falls = 2,425 feet
2. Sarah has some blue marbles, twice as many red marbles as blue, and 8 yellow marbles. If she has a total of 32 marbles, how
many red marbles does she have?
A.8
B.12
C.16
D.24
Given:
Number of blue marbles, twice as many red marbles as blue, and 8 yellow marbles.
She has a total of 32 marbles.
To find:
The number of red marbles.
Solution:
Let number of blue marbles be x.
Then, number of red marbles = 2x
Number of yellow marbles = 8
Total number of marbles = 32
[tex]x+2x+8=32[/tex]
[tex]3x=32-8[/tex]
[tex]3x=24[/tex]
[tex]x=8[/tex]
Now,
Number of red marbles [tex]=2(8)=16[/tex]
Therefore, there are 16 red marbles.
When = 3, what will the value for y be for the equation - 4x + 5y = 18?
If x equals 3 then y must equal 1.2
Answer: y=6
-4(3)+5y=18
-12+5y=18
add 12 to both sides
-12+5y+12=18+12
5y=18+12
5y=30
divide both sides by 5
5y÷5=30÷5
y=30÷5
y=6

Peyton is collecting data on the lunch habits of students at Hyattsville Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Hyattsville Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch? *
Answer:
Answer: Around 1000 students would buy a school lunch.
Step-by-step explanation:
We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.
In total we have 20 + 14 = 34 students, this will be our 100%.
The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.
p1 = (14/34)*100% = 41.18%
And the percentage of students that buy lunch at school can be computed in the same way:
p2= (20/34)*100% = 58.82%
Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.
Then the exact number will be:
N = (58.82%/100%)*1700 = 1000
Around 1000 students would buy a school lunch.
