When two parallel lines are intersected by a transversal, the same-side exterior angles are supplementary. That means that their sum is 180.
Using that logic, if the two roads were parallel, then the sum of their same-side exterior angles will add up to 180. Yet their same-side exterior angles add up to 170 (130 + 40 = 170), hence they can't be parallel.
See the drawing attached below.
Using supplmenatry angles (two angles whose sum of measures add up to 180 or a straight line), we can say that:
m<DIE + m<HID = 18
40 + m<HID = 180
m<HID = 140
Similarly:
m<BHC + m<CHI = 180
130 + m<CHI = 180
m<CHI = 50
Using verticle angles therome, (when two lines intersect, the angles opposite to eachother are congruent, or have the same measure), we can say that:
m<DIE = m<GIH = 40
m<GIE = m<HID = 140
m<CHI = m<AHB = 50
m<BHC = m<AHI = 130

The sum of two numbers is 46. The difference of those numbers is 22. What are the two numbers?
Answer:
34 and 12
Step-by-step explanation:
so two numbers are x and x-22
then x+x-22=46
2x=68
x=34
x-22 = 12
The numbers are 34 and 12, which gives sum 46 and difference 22.
What is algebra?Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.
Let the two numbers are a and b.
According to given conditions,
The sum of a and b is 46,
And the difference of a and b is 22.
Implies that,
a + b = 46 (1)
a - b = 22 (2)
Add equation (1) and (2),
2a = 68
a = 34
Substitute the value of a in equation 1 to get the value of b,
34 + b = 46
b = 46 - 34
b = 12
The required numbers are 34 and 12.

Answer:
C. [tex] d = \frac{at^2}{2} [/tex]
Step-by-step explanation:
Given:
[tex] t = \sqrt{\frac{2d}{a}} [/tex]
Required:
Make d the subject of the formula.
SOLUTION:
[tex] t = \sqrt{\frac{2d}{a}} [/tex]
Square both sides
[tex] t^2 = (\sqrt{\frac{2d}{a}})^2 [/tex]
[tex] t^2 = \frac{2d}{a} [/tex]
Multiply both sides by a

a washer and dryer cost $657 combined. The washer costs $43 less than the dryer. What's the cost of the dryer?
Answer:
The answer is $614
w + d = 657
657 divided by 2 is 328.5
328.5 - 43 285.5 (that would be washer)
Answer: 657 - 285.5 = 371.5

Answer:
h(x)=20
Step-by-step explanation:
x=5

15+5
20
Hope this helps!
Answer:20
Step-by-step explanation:
Hello!
So first you want to plug in 5 to all of the x
h(5) = 3(5) + 5
No you want to do 3(5)
3(5) = 15
h(5) = 15 + 5
Now you add 15 + 5
15 + 5 = 20
h(5) = 20
So your answer is 20

A.The product between 3 and a number is no less than 9.
B.The product between 3 and a number is greater than 9.
C.The product between 3 and a number is no more than 9.
D.The product between 3 and a number is less than 9.
Answer:
Let's define the symbols:
x < y
means that x is strictly less than y.
x ≤ y
means that x is less than or equal to y.
(both of these signs can be in the other direction, take that in mind).
A) " a is always less than another number b"
Here we should have:
a < b.
a is always less than the other number b.
This is not in the options, so i suppose that there is a mistake in the question.
B) The expression "above" is not shown here, so i will just writhe the correspondent expression for each option, and you can see which one matches with the expression above.
a) "The product between 3 and a number is no less than 9"
3*n ≥ 9.
b) "The product between 3 and a number is greater than 9."
3*n > 9
c) "The product between 3 and a number is no more than 9"
3*n ≤ 9
d) "The product between 3 and a number is less than 9"

This is a vocabulary question. The angles named by the relationships A-E are angles that have the transversal as a common side. "Interior" and "exterior" refers to the space between the crossing lines, or outside the crossing lines, respectively. "Alternate" means the angles are on opposite sides of the transversal; "consecutive" means they are on the same side of the transversal.
Angles are "corresponding" if they are in the same direction from the point of intersection where the transversal crosses the two lines. The angles will be "consecutive", but one will be interior and the other will be exterior.
4. angle 9 is left of q, above r; angle 16 is right of q and below s, so these are alternate exterior angles, C.
__
5. angle 3 is below r and left of p; angle 5 is above s and left of p, so these are consecutive interior angles, D.
__
6. angle 7 is below s and left of p; angle 15 is below s and left of q, so these are corresponding angles, A.
__
7. angle 1 is above r and left of p; angle 10 is above r and right of q, so these are consecutive exterior angles, E.
__
8. angle 2 is above r and right of p; angle 11 is below r and left of q, so these are alternate interior angles, B.

Each square in the grid is a unit square with an area of 1 square unit. What is the area of the figure? square units
Answer:
The total area of the figure is: 16 square units
Step-by-step explanation:
The Area is basically a measure of how much space in square units there is inside an object.
Given that each square in the grid is a unit square with an area of 1 square unit.
The figure clearly shows that there are 14 complete squares and 4 half square units.
Thus, the total area of the figure is:
(1 × 14) + (1/2 × 4)
=14 + 2
= 16 square units
Therefore, the total area of the figure is: 16 square units

Answer:
1/13
Step-by-step explanation:
Ice cream
starting = 2/3 full
After Jenna's shift = 1/6 of the tub
Total Time = 6.5hours
Amount of ice cream consumed = [tex]\frac{2}{3} - \frac{1}{6}[/tex]
= [tex]\frac{1}{2}[/tex] = 0.5
Rate per hour = amount of ice cream consumed -=/ total time
= 0.5/6.5 = 1/13 ice cream consumed per hour

Answer:
-457.96
Step-by-step explanation:
Step-by-step explanation:
273.15 + °C = K
°C = K - 273.15
0.95K to °C = 0.95 - 273.15 = -272.2°C
°C to °F
(9/5 °C) + 32 = °F
(9/5 × -272.2) + 32 = °F
-489.96 + 32 = °F
= -457.96°F

An exterior angle of a triangle is 152°. If the non-adjacent angles are congruent, then what are the measures of all of the interior angles of the triangle?
a. 62°, 59°, 59°
b. 90°, 45°, 45°
c. 152°, 14°, 14°
d. 28°, 76°, 76°
9514 1404 393
Answer:
d. 28°, 76°, 76°
Step-by-step explanation:
The sum of the "non-adjacent" interior angles of the triangle is equal to the exterior angle, so is 152°. If those angles are congruent, each is half of 152°, or 76°. The remaining angle is the supplement to 152°, so is 180-152 = 28 degrees.
The interior angles are 28°, 76°, 76°.

What si the equation in slope intercept form of the line that passes through the points (-4,2) and (12,6)
Answer:
b = -12
Step-by-step explanation:
In order to find the slope intercept you must first find the slope of the given points.
[tex]-4,2 = 12,6[/tex]
[tex]S=\frac{y2-y1}{x2-x1}[/tex]
Substitute:
[tex]\frac{12--4}{6-2}[/tex]
[tex]12--4=12+4=16[/tex]
[tex]6-2=4[/tex]
[tex]S=\frac{16}{4}[/tex]
Now find the slope intercept
[tex]16\div4=4[/tex]
[tex]SI=y=mx+b[/tex]
Substitute:
[tex]12=4\times6+b[/tex]
Solve:
[tex]4\times6=24[/tex]
[tex]12=24+b[/tex]
Subtract 24 on both sides:
[tex]12-24=-12[/tex]
[tex]x=-12[/tex]
[tex]y=-12[/tex]
