Answer:
8) scale factor: 3
angles Q & L, S & N, r & M
sides 10 x 3 = 30, 6 x 3 = 18, 13 x 3 = 39
9) scale factor: 0.4
angles B & F, C & G, D & H, A & E
sides 9 x 0.4 = 3.6, 7.5 x 0.4 = 3, 10 x 0.4 = 4, 12 x 0.4 = 4.8
The scale factor for part (8) is 3, angles Q & L, S & N, R & M, for part (9) is 0.4 and angles of pair are congruent B & F, C & G, D & H, A & E
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object, known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

Scale factor for the triangle LMN:
Let's suppose the scale factor is x
3x= 30 ⇒ x = 3
6x= 18 ⇒ x = 3
13x=39 ⇒ x = 3
So the scale factor is 3
Angles Q & L, S & N, R & M
39/13 = 30/10 = 18/6 = 3
9)
Scale factor for the triangle LMN:
Let's suppose the scale factor is y
12y= 4.8 ⇒ x = 0.4
9x= 3.6 ⇒ x = 0.4
10x=4 ⇒ x = 0.4
So the scale factor is 0.4
Angles B & F, C & G, D & H, A & E
4.8/12 = 3.6/9 = 4/10 = 0.4
Thus, the scale factor for part (8) is 3, angles Q & L, S & N, R & M, for part (9) is 0.4 and angles of pair are congruent B & F, C & G, D & H, A & E

Answer:
[tex]\dfrac{-79}{126}[/tex]
Step-by-step explanation:
The given expression is :
[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}[/tex]
The LCM of 3,7,9 and 14 is 126
So,
[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}=\dfrac{42(-2)+18(5)+14(-8)+9(3)}{126}\\\\=\dfrac{-79}{126}[/tex]
So, the value of the given expression is equal to [tex]\dfrac{-79}{126}[/tex].

At the clothing store, 1/8 of the clothes are shirts. Of the shirts 1/4 are green. What fraction of the clothing in the store are green shirts?
Answer:
1/32
Step-by-step explanation:
So we know that green shirts can be represented by 1/4 of 1/8. It's 1/4 of the 1/8 of shirts in the store. The key word here is "of," which means multiplication.
So you can replace 1/4 of 1/8 with:
[tex]\frac{1}{4} x \frac{1}{8}[/tex]
To multiply fractions, it's really simple: multiply the denominator with the denominator and the numerator with the numerator.
[tex]\frac{1}{4} x \frac{1}{8} = \frac{1}{32}[/tex]
So 1/32 of the entire store is green shirts.

Which of the following statements are correct?
Select all that apply.
Triangle ABC is congruent to triangle DEF.
Triangle DEF is congruent to triangle GHI.
Triangle ABC is congruent to triangle GHI.
All three triangles are congruent.
Answer:
Triangle DEF is congruent to triangle GHI.
You can use the process of elimination to get that. All three are not because when u look at their angles and their side. Triangle ABC is not like the others. And abc is not congruent to def because of the angles and the sides.
Step-by-step explanation:
:D
Answer: I think you just answered your own question with the first sentence you wrote. Still not sure what the answer is?

A map uses a scale of 3/4 in = 80 miles. If two buildings are 60 miles apart in real life, how far apart would they be drawn on the map?
Given:
The scale of a map is [tex]\dfrac{3}{4}\ in=80\ miles[/tex].
The distance between two buildings is 60 miles.
To find:
The distance between the given building on the map.
Solution:
We have,
[tex]\dfrac{3}{4}\ in=80\ miles[/tex]
It means, 80 miles in real life = [tex]\dfrac{3}{4}\ in[/tex] on the map.
1 mile in real life = [tex]\dfrac{3}{4\times 80}\ in[/tex] on the map.
60 mile in real life = [tex]\dfrac{3\times 60}{4\times 80}\ in[/tex] on the map.
= [tex]\dfrac{180}{320}\ in[/tex] on the map.
= [tex]\dfrac{9}{16}\ in[/tex] on the map.
Therefore, the buildings are [tex]\dfrac{9}{16}\ in[/tex] apart on the map.

Madeline invests $25,000 in an account that offers a compound interest rate
of 9.5% per year. Which of the following is the correct equation for how much
Madeline will have after 8 years?
The correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex].
What is compound interest ?Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest
Amount [tex]=P(1+\frac{R}{100})^t[/tex]
We have,
Principal [tex]=\$25,000[/tex]
Rate[tex]=9.5\%[/tex]
Time [tex]=8[/tex] years
Now,
Using the above mentioned formula,
Amount [tex]=P(1+\frac{R}{100})^t[/tex]
[tex]=25000(1+\frac{9.5}{100})^8[/tex]
Amount [tex]=25000(1+0.095)^8[/tex]
So, the equation for final amount is [tex]25000(1+0.095)^8[/tex].
Hence, we can say that the correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex] .

If the length of the 45° region of this circle is 10 inches, what is the radius of the circle? Use and round to the nearest tenth.
Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
