Answer:
A. △ABC and △JKL are similar.
Step-by-step explanation:
Since three angles of one triangle are congruent to three corresponding angles of the other triangle, the triangles are either congruent or similar. Since the side of one triangle is twice the length of the corresponding side of the other triangle, then the triangles are not congruent, but they are similar.
A. △ABC and △JKL are similar.
Answer:
. △ABC and △JKL are similar.

Explain two ways you can use a number line to order the integers –3, +1, and –10. PLEASE ASAP
Answer:
Step-by-step explanation:
From least to greatest: -10, -3, +1. From greatest to least: +1, -3, -10.
1st way: Just look at it.
2nd way: See which numbers are to the left of 0 on the number line. Those are your smaller (negative) numbers. The numbers that are on the right side of 0 are your bigger (positive) numbers.
Answer:
Order by value: On a number line, the integers to the left are less than the integers to the right. Order by magnitude: On a number line, the integers farther from zero have a greater magnitude. Least to greatest value: –10, –3, +1. Least to greatest magnitude: +1, –3, –10.
Step-by-step explanation:
Which did you include in your response? Check all that apply.
You can order by value.
You can order by magnitude.
Ordering from least to greatest value, the list is –10, –3, +1.
Ordering from least to greatest magnitude, the list is +1, –3, –10.

This is not a function. The input 7 in set A maps to outputs -1 and -3 at the same time in set B, which is why we don't have a function.
For a function to be possible, each input must map to exactly one output only.
a photo graph measuring 8cm by 6cm is enlarged by a ratio of 11 : 4 what are the dimensions of new print ?
Answer:
22cm and 16 1/2 cm is the answer
Write the ratio as a fraction and multiply with each dimension
If a photograph is 8cm by 6cm, the new dimensions after enlarging the photograph by a ratio of 11:4 would be: 22 cm by 16.5 cm.
Given the following measurement of a photograph:
8 cm by 6 cmTo enlarge the photograph using a scale factor of 11:4 (11/4), multiply the scale factor by each of the dimensions.
Thus:
8 x 11/4 = 22 cm6 x 11/4 = 16.5 cmTherefore, if a photograph is 8cm by 6cm, the new dimensions after enlarging the photograph by a ratio of 11:4 would be: 22 cm by 16.5 cm.

What is the Inverse Equation
f(x) =6x-1 ?? please I need help!
Answer:
[tex]f^{-1}(x)=\frac{x+1}{6}[/tex]
Step-by-step explanation:
So we have the function:
[tex]f(x)=6x-1[/tex]
To find the inverse function, switch x and f(x), change f(x) to f⁻¹(x), and solve for f⁻¹(x). Therefore:
[tex]f(x)=6x-1[/tex]
Switch:
[tex]x=6f^{-1}(x)-1[/tex]
Add 1 to both sides:
[tex]x+1=6f^{-1}(x)[/tex]
Divide both sides by 6:
[tex]f^{-1}(x)=\frac{x+1}{6}[/tex]

Which of the following circumstances would likely make completing the square th
best method for solving a quadratic equation?
The leading coefficient is 1 and the linear term coefficient is an even number
The leading coefficient is not 1 and the constant is large
The difference of 2 perfect squares
The difference of 2 perfect cubes
Answer:
The leading coefficient is 1 and the linear term coefficient is an even number
Step-by-step explanation:
Leading coefficient must be one for the application of completing square method. If the completing square is not one than we must apply other methods like Ac method, quadratic formula to solve the equation. To solve the equation with completing square the numerical value must be on other side of the equation. In this method we multiply linear term’s coefficient with one-half and square it therefore, completing square is suitable method for the equation having leading coefficient is 1 and linear coefficient is even.

Write and solve an equation for the situation. The perimeter of a parallelogram is 48 meters. The width of the parallelogram is 8 meters less than its length. Find the length and the width of the parallelogram.
Answer:
length=16 and width = 8
Step-by-step explanation:
p= 2(length + width) ........ p= 48 m
width=length-8
48=2(length + length -8)
48= 2(2length -8)
48= 4 length-16
48 +16 = 4 length
[tex] \frac{64}{4} = length [/tex]
length =16
Width = length - 8
width = 16 - 8
width = 8

Rectangle T R E C is shown. Diagonals are drawn from point R to point C and from point E to point T and intersect in the middle. The distance from point R to the middle is 2 x minus 3 and the distance from the middle point to point C is x + 7. TREC is a rectangle. What is the length of ET? 10 units 17 units 20 units 34 units
Answer:
34 units
Step-by-step explanation:
Given a rectangle TREC, with RC and ET being the diagonal both intersecting at the middle, then the following are true;
Let O be the point of intersection of RC and ET;
RO+OC = RC
Given the distance from point R to the middle as 2 x - 3, then RO = 2x-3 and if the distance from the middle point to point C is x + 7, then OC = x+7
Since they intersect in the middle, RO = OC
2x-3 = x+7
Collect like terms
2x-x = 7+3
x = 10
RO = 2x-3
RO = 2(10)-3
RO = 17
since RO = OC, then OC = 17units
Note that both diagonal RC and ET inyetsect at the middle O hence diagonal RC = ET = RO+OC
RC = ET = 17+17
RC = ET = 34units
Hence the length of ET is 34 units
Answer:
34 units

Between 10pm and 7:45am, the water level in a swimming pool decreased by 3/8 in. Assuming that the water decreased at a constant rate, how much did the water level drop each hour?
Answer:
[tex]\frac{1}{26}[/tex] inches
Step-by-step explanation:
In order to solve this problem, we need to create a ratio.
Since we're looking for the rate per hour, we need to find how long it is from 10pm to 7:45am.
10pm + 2 hours = 12 AM
12 AM + 7.75 hours = 7:45 AM
So in total, it's 9.75 hours.
[tex]\frac{3}{8}[/tex] is the same as 0.375.
Our fraction will become [tex]\frac{0.375}{9.75}[/tex], which can simplify down to [tex]\frac{1}{26}[/tex].
Now we can create the proportion:
[tex]\frac{1}{26}=\frac{x}{1}[/tex]
Now we solve for x by cross multiplying.
[tex]1\cdot1=1\\\\1\div26=\frac{1}{26}[/tex]

The container of orange juice held 5 and one-third cups of juice. If a serving of orange juice is StartFraction 7 Over 8 EndFraction of a cup of orange juice, to the nearest whole serving, how many servings were in the container? 5 servings 6 servings 15 servings 19 servings
Answer:
6 servings
Step-by-step explanation:
To find the number of servings, divide the total amount by the quantity per serving.
You can compute this using a calculator:
5.333/0.875 ≈ 6.095 ≈ 6 servings
__
Or, you can do the mixed-number math:
(5 1/3)/(7/8) = (16/3)(8/7) = 128/21 = 6 2/21 ≈ 6
There were 6 servings in the container.
