HELP DUE IN 15 MINS! ΔLMN ~ ΔPQR. Which of the following sets of side lengths could be those of ΔLMN?
A. 2 cm, 3 cm, 4 cm
B. 6 cm, 7 cm, 8 cm
C. 8 cm, 15 cm, 17 cm
D. 9 cm, 12 cm, 15 cm
Answer: D.
Step-by-step explanation:
If the triangle PQR has sides from biggest to smallest 3,4,5 we need another triangle with a similar ratio to compare it to.
9/3= 3 12/3=4 15/3=5
So the answer is D because I can divide all the sides of the new triangle by the same number to get the sides of triangle PQR
Answer:
D. 9 cm, 12 cm, 15 cmStep-by-step explanation:
Given
ΔLMN ~ ΔPQRΔPQR has sides ratio 3 : 4 : 5
ΔLMN should also have same ratio and the ratio of corresponding sides should be same.

what is the diameter in the circle above
7
3.5
14
3.14
Answer:
14
Step-by-step explanation:
The diameter is the length from one point on the circle to another, passing through the center. The radius is the length from a point on the circle to its center, so we can always find the diameter by doubling the radius. In this case, with a radius of 7, our diameter is 7 · 2 = 14

Where do the graphs of y = 4x - 3 and y = 9x - 13 intersect?
Someone help me asap plz!
Answer:
(2, 5 )
Step-by-step explanation:
To find the point of intersection, solve the equations simultaneously.
y = 4x - 3 → (1)
y = 9x - 13 → (2)
Substitute y = 9x - 13 into (1)
9x - 13 = 4x - 3 ( subtract 4x from both sides )
5x - 13 = - 3 ( add 13 to both sides )
5x = 10 ( divide both sides by 5 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
y = 4(2) - 3 = 8 - 3 = 5
point of intersection = (2, 5 )

Kishany is investing in a savings account that earns 3.85% interest compounded annually. How much will Kishany have in the account at the end of the 3rd year if she deposits $600 in the account?
a
$2,310
b
$672.00
c
$558.38
d
$669.30
Answer:
b: $672
Step-by-step explanation:
The appropriate formula for use here is the Compound Amount formula:
A = P(1 + r)^n, where r is the annual interest rate as a decimal fraction, P is the principal (up front amount invested), and t is time measured in years.
Here we have A = ($600)(1 + 0.0385)^3, or:
A = ($600)(1.0385)^3
A = $672 (matches answer b)

A variable needs to be eliminated to solve the system of equations below. Choose the correct first step.
-9x + 4y = 17
9x + 7y = 5
A. Subtract to eliminate x.
B. Subtract to eliminate y.
C. Add to eliminate y.
D. Add to eliminate x.
Answer:
Add to eliminate X that way it will be much easier to solve the system of equations.
Step-by-step explanation:
-9x + 4y = 17
9x + 7y = 5
11y = 22
Last step is to divide both sides by 11 and your answer should come to 2!

Step-by-step explanation:
name the line of reflection used to map each primate to its image
state the coordinate of the image of the given point B (-10, -6) under a dilation with a center at the orgin with the given scale factor k = 1/2
The coordinate of the point B ( -10 , -6 ) after the dilation of -1/2 is given by the coordinate B ' ( -5 , -3 )
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
Given data ,
Let the coordinate of the point be represented as B
The value of B = B ( -10 , -6 )
Now , the dilation factor is given by k = 1/2
So , multiply by 1/2 on the x coordinate and y coordinate of the point B , we get
The coordinate of the point B' after the dilation is
B' = B' ( -10/2 , -6/2 )
So , on simplifying the equation , we get
B' = B' ( -5 , -3 )
Hence , the point after dilation is B' ( -5 , -3 )

Mr. Ramirez informs the students that some of the trees they plant will not survive their first year, so the class will take precautions to monitor the trees to give them the best chance of survival.
Abby does some research and finds that, on average, 3 out of every 25 trees planted will die their first year.
What percentage of the trees will survive their first year?
Answer:
88%
Step-by-step explanation:
Since 25 is 1/4 of 100, you can simply subtract 3 from 25 and then, your answer from that you want to multiply it by 4. Or you can make it into a fraction if that helps you visualize what's going on. It'll be 22 over 25, now multiply both numerator and denominator by 4.
