Answer:
C = 112, A = 150, D = 30, B = 38
Step-by-step explanation:
I solved C first using:
30+38+c = 180 (angles along a straight line should add up to 180 since a whole circle is 360)
-
I solved A by looking across from C.
Angles on opposite sides should mirror each other but A includes 38* + C
Just by doing 112 + 38 you get 150.
-
I solved D by looking at 30*, alternative interior angles are the same so D is 30*.
-
I solved B by taking C (112) and D (30) and adding them together and subtracting from 180.
Interior angles of a triangle should all add up to 180,
112 + 30 + B = 180
From this I got that B was 38.
Alternatively you can find this out by looking at the 38 degrees, corresponding congruent angles are always the same.
I suggest reviewing this angles sheet if you're ever stuck in the future.
Answer:
C = 112, A = 150, D = 30, B = 38

Find the measure of XCY. PLEASE HELP ME AND SHOW WORK
Answer:
Measure of angle XCY is 60°.
Step-by-step explanation:
"Measure of all inscribed angles by the same arc in one segment of the circle are equal"
Using this property in the given circle,
m∠XWY = m∠XCY
60x = 61x - 1
61x - 60x = 1
x = 1
By substituting the value of 'x' in the measure of ∠XCY,
m∠XCY = 61x - 1
= 61(1) - 1
= 61 - 1
= 60°
Therefore, measure of angle XCY is 60°.
There are 45 rows of tomato plants in the hydroponics farm at O'Brien's Farms Each row has 14 plants. 2/3 of the plants have sprouted. How many sprouted plants does O'Brien's have?
Answer: 420 sprouted plants
Step-by-step explanation:
First find the total number of tomato plants in the farm.
= Number of rows * No. of plants per row
= 45 * 14
= 630 plants
2/3 of them have sprouted so the number of sprouted plants is:
= 2/3 * 630
= 420 sprouted plants

Write an equation in slope-intercept form of the line that passes through the given points.
Answer:
y = 2
Step-by-step explanation:
Since the y- coordinates of the ordered pairs are all 2
This indicates the line is horizontal with equation y = c
where c is the value of the y- coordinates the line passes through, then
y = 2 ← equation of line
Represent 0.533 (only the last 3 is bar number) into a rational number
Answer:
[tex]\frac{8}{15}[/tex]
Step-by-step explanation:
We require 2 equations with the repeating 3 placed after the decimal point.
let x = 0.5333.. ( multiply both sides by 10 and 100 )
10x = 5.333... → (1)
100x = 53.333... → (2)
Subtract (1) from (2) tus eliminating the repeating 3
90x = 48 ( divide both sides by 90 )
x = [tex]\frac{48}{90}[/tex] = [tex]\frac{8}{15}[/tex]
Answer:
IT IS 8/15
Step-by-step explanation: Divide and multiply the fraction from 100 to tens

x^2 + 4x − 9 = 0
I have no idea what to do! Help
Answer:
X= 1.8
Step-by-step explanation:
If I’m not mistaken then this is how to work it out. X^2 + 4x -9 =0. X^2 + 4x would be 5x. 5x - 9 = 0. +9 on both sides. 5x=9. Divide by 5 on each side. X= 1.8

A geologist drew a scale drawing of a section of a quartz layer she saw in a cliff. The scale drawing of the layer is 4 cm high and 28 cm long. If the actual layer is 0.2 meters high, what is the area of the actual quartz layer section she saw?
Answer:
[tex]0.28\ \text{m}^2[/tex]
Step-by-step explanation:
[tex]4\ \text{cm}=0.2\ \text{m}[/tex]
[tex]1\ \text{cm}=\dfrac{0.2}{4}=0.05\ \text{m}[/tex]
[tex]28\ \text{cm}=28\times 0.05=1.4\ \text{m}[/tex]
The height of the layer is 0.2 m and the length is 1.4 m
Area is given by
[tex]0.2\times 1.4=0.28\ \text{m}^2[/tex]
Area of the actual quartz layer section is [tex]0.28\ \text{m}^2[/tex].

S - Subtract
PEMDAS, is just an order of operations...
In our order above, Multiplying comes BEFORE addition OR Subtraction...
40 x 0 = 0
Then moving to the front...
40 - 0 = 40...
Lastly, 40 + 1 = 41
Answer is 41

Answer:
The angle marked E is 120 degrees
Step-by-step explanation:
Here, we want to get the value of the angle marked E
when two triangles are similar/congruent, we have equal angle measures
Using the markings, we can deduce the following relationships;
4y -28 = 83 + y
4y-y = 83 + 28
3y = 111
y = 111/3
y = 37
So, we have;
4y-28 as
4(37) - 28
= 120

answer this question for brainilest and 20 points
Answer:
x = 5, y = 4
Step-by-step explanation:
Solve for one variable. x will be simpler using the second equation.
3x = 15
Divide by 3.
x = 5.
Now put that into the other equation.
4x + 5y = 40
Substitute variable.
4(5) + 5y = 40
20 + 5y = 40
Subtract 20 from both sides.
5y = 20
Divide by 5.
y = 4.
