4) Which pair of triangles is congruent by Angle - Angle- Side?
We want to see which pair of triangles is equivalent by the Angle-Angle-Side criteria.
The correct option is 2, where we have two equal angles, and the bottom side is equal in both triangles.
The Angle-Angle-Side criteria means that if two triangles have an equal side, and the two correspondent angles also are equal, then these triangles are equivalent.
So we just need to see (by notation, not by how the triangles look like) in which ones we have two equal angles and one equal side.
That one is the second pair of triangles.
We can see that the two top angles are equal (two curves) and that the left angle in the left triangle is equal to the right angle on the other triangle (so we have two equal angles).
Also, the bottom side is equal on both triangles.
Then the angle-angle-side criteria is meet, meaning that these two triangles are equivalent.

The difference between the roots of the quadratic equation x2 -14x +q =0 is 6. Find q
9514 1404 393
Answer:
q = 40
Step-by-step explanation:
When the quadratic has roots p and r, it can be factored as ...
(x -p)(x -r) = x² -(p+r)x +pr
So, the sum of the roots is 14, and their difference is 6. This lets us find the roots from ...
p + r = 14
p - r = 6
2p = 20 . . . add the two equations
p = 10
r = 14 -p = 4
The value of interest is then ...
q = pr = (10)(4)
q = 40
__
The graph shows the roots to be 4 and 10, as we found.
The landscaper bought small and large bags of premium bags. The total spent on the 25 bags is $239.75. Four large bags cost $61.25. The remaining small bags each cost the same amount. How much did each small bag cost?
Answer:
Each small bag cost $8.5

Alice made lemonade for her school's fall festival as a fundraiser. She made a total of 5 gallons, which is 80 cups. They sold, on average 16 cups per hour. Write an equation that represents y, the number of cups of lemonade remaining, after x hours
Answer:
y = 80-16x
Step-by-step explanation:
She made a total of 80 cups and sells 16 cups per hour
So in x hours she would have sold 16 * x = 16x cups
So the number of cups remaining will be;
y = 80-16x

A figure is translated 6 units to the left. How will the coordinates change?
The x-coordinates will decrease by 6.
The y-coordinates will increase by 6.
The x-coordinates will increase by 6.
The y-coordinates will decrease by 6.
Answer:
The x-coordinates will decrease by 6.
Step-by-step explanation:
When looking at a graph, the left side has lower numbers than the right side on the x-axis. If you are moving something to the left you are decreasing. Also it can't be on the y-axis becuase the y-axis means that you are increasing or virtically.
Answer: The x-coordinates will decrease by 6.

A person breathes 2.5 x 10^-4 in about cubic meters of air per second. How long does it take to breathe in 2.5 cubic meters of air?
Answer:
10⁴ seconds
Step-by-step explanation:
Given that,
A person breathes [tex]2.5\times 10^{-4}[/tex] in about cubic meters of air per second.
We need to find time taken to breathe 2.5 cubic meters of air.
In 1 sec = [tex]2.5\times 10^{-4}[/tex] m³ of air breathe
Let in x seconds, 2.5 m³ of air taken by the person.
[tex]x=\dfrac{2.5}{2.5\times 10^{-4}}\\\\x=10^4\ s[/tex]
Hence, in 10⁴ seconds 2.5 m³ of air is taken by the person.

One pump can empty a swimming pool in 4 hours while a second pump can empty the same pool in 5 hours. How many hours long will it take the two pumps working together to drain the pool? Round your answer to the nearest tenth.
Answer:
It takes 20/9 hours for both pumps to completely drain the pool.
Step-by-step explanation:
The rate of the first pump is emptying 1/4 of the pool in an hour.
The rate of the second pump is emptying 1/5 of the pool in an hour
The combined rate of these two per hour is
1/4 + 1/5 = 9/20
The time taken to completely drain the pool is 1 (the whole pool) divided by the combined rate. So:
9/20x = 1
x = 1/ ⁹⁄₂₀
x = 20/9
It takes 20/9 hours for both pumps to completely drain the pool.
Put this into the calculator to round to the nearest tenth.
Lauren was asked to solve for x. She thinks that x equals 114 degrees because the Angle X is congruent to the 114 degree angle. Is Lauren correct? why or why not
Answer:
no
Step-by-step explanation:
x and 114° are same- side interior angles and are supplementary, then
x = 180 - 114 = 66
Put the following equation of a line into slope-intercept form,simplifying all fractions 3x+3y=24
A linear equation in slope intercept form is: [tex]y = mx+ c[/tex].
The slope intercept form of [tex]3x + 3y = 24[/tex] is [tex]y = -x + 8[/tex]
Given
[tex]3x + 3y = 24[/tex]
Subtract 3x from both sides
[tex]3x - 3x + 3y = -3x + 24[/tex]
[tex]3y = -3x + 24[/tex]
Divide both sides by 3
[tex]\frac{3y}3 = \frac{-3x}3 + \frac{24}3[/tex]
[tex]y = -x + 8[/tex]
By comparing [tex]y = -x + 8[/tex] and [tex]y =mx + c[/tex];
We can conclude that: [tex]y = -x + 8[/tex] is the slope intercept form of [tex]3x + 3y = 24[/tex]
