Find scale factor
QR=9unitsQ'R'=3unitsScale factor:-
k=3/9k=1/3Yes Option A is correct
Answer:
A. The edge lengths of the smaller figure are less than half those of the large figure.
[tex]\sf Scale\:factor=\dfrac13[/tex]
Step-by-step explanation:
From inspection of the graph, the pre-image is QRST and the dilated image is Q'R'S'T'.
We can see that Q'R'S'T' is a reduction of QRST since it is smaller.
Inspect the length of the corresponding line segments of both images and compare.
T'S' = 3 units
TS = 9 units
[tex]\sf \dfrac{T'S'}{TS}=\dfrac{3}{9}=\dfrac13[/tex]
Therefore, T'S' is [tex]\sf \frac13[/tex] the length of TS.
As [tex]\sf \frac13 < \frac12[/tex], the edge lengths of the smaller figure are less than half those of the large figure (answer option A)
The scale factor is the amount we have to multiply the sides of QRST by to get Q'R'S'T'. Therefore, the scale factor for the side lengths in this dilation is [tex]\sf \frac13[/tex]

I will be using pythagorean triples for some, but you can use sqrt(a^2+b^2)=c^2
1. 12 13 5 x=5
2. 3 4 5 x=5
3. sqrt(14.7^2-11.9^2)=sqrt(74.48) or around 9 (root is irrational)
4. sqrt(15.4^2-6.3^2)=sqrt(197.47) or around 14 (same thing)
5. sqrt(15^2-11^2)=2*sqrt(26) or around 10
6. sqrt(4^2-sqrt(6)^2)=sqrt(16-6)=sqrt(10) or around 3
7. sqrt(12^2+9^2)= 15, so it is a right triangle
8. 9, 12, 15 divide by 3- 3, 4, 5 pythagorean triple - is a right triangle
9. 9, 12, 15-17>15, obtuse
10. sqrt(20.1^2+18^2)=20.4 - 20.1<20.4, acute
11. sqrt(4.8^2+28.6^2)=29, 29=29, right

A sock drawer contains 10 white socks, 6 black socks, and 8 blue socks.
If 3 socks are chosen at random, without replacing the first sock, what is the probability of getting first a black sock, then a white sock, then a blue sock?
Thanks!
Answers
Answer:
As a fraction: 10/253
As a decimal: 0.0395 (3 sf)
As a percentage: 3.95% (3 sf)
Step-by-step explanation:
white socks = 10black socks = 6blue socks = 8Total number of socks = 24Therefore, the probability of picking a black sock is:
P(black) = 6/24
As the sock is NOT replaced, we now have one less black sock:
white socks = 10black socks = 5blue socks = 8Total number of socks = 23So the probability of picking a white sock:
P(white) = 10/23
As the sock is NOT replaced, we now have one less black sock and one less white sock:
white socks = 9black socks = 5blue socks = 8Total number of socks = 22So the probability of picking a blue sock:
P(blue) = 8/22
Therefore, P(black) and P(white) and P(blue) is:
6/24 x 10/23 x 8/22 = 480/12144 = 10/253 = 0.03952... = 3.95%

Answers
There would be 22 red chips in the bucket containing 66 total chips.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Let us assume the ratio of red chips to blue chips is 1:2.
Hence, if there 44 blue chips in the bucket:
(2/3) * total chips = 44
Total chips = 66
Number of red chips = (1/3) * 66 = 22
There would be 22 red chips in the bucket containing 66 total chips.

now we get rid of the coefficient on y.
5y/5=(5-4x)/5

I know what Y is but I don't know X
Answers
Answer: y = 120 degrees, x = 31 degrees
Step-by-step explanation:
Y is 120 degrees because same-side exterior angles are supplementary.
Therefore, 60+ y = 180; y = 120
Since "y" and "4x-64" are supplementary, they add up to 180.
We already know y as 120.
So 120 + 4x - 64 = 180
4x = 124
x = 31

30°
Answers
Answer:
x=50
Step-by-step explanation:
angles in a triangle add up to 180 degrees
hence, 50 + 2x + 30 = 180
solving for x
50 + 2x + 30 = 180
combine like terms
2x + 80 = 180
subtract 180 from both sides
2x = 100
divide both sides by 2
x = 50
Answer:
x=50
Step-by-step explanation:
50°+30°+2x = 180° (sum of all angles of a triangle)
or, 2x +80°= 180°
or, 2x = 180°-80°
or, 2x=100°
or, x= 100°/2
therefore,x°=50°
Again,
2x = 2×50°=100°

Arturo bought some belts online for $73. He used a coupon code to get a 20%
discount. The website also applied a 15% processing fee to the price after the
discount. How much was the processing fee? Round to the nearest cent.
Answers
Answer:
The processing fee will cost $8.76
Step-by-step explanation:
the price after the discount:
20% = 0.2
100% = 1
1 - 0.2 = 0.8
0.8
$73 • 0.8 = $58.4
cost of processing fee:
15% = 0.15
$58.4 • 0.15 = $8.76
