Answer:
Option (1) and (3)
Step-by-step explanation:
Properties for the similarity of two figures,
1). Angles of the figures should be same.
2). Corresponding sides of both the figures should be proportional.
Since all the pairs have same angles, we will use the second property to prove these polygons similar.
Option (1)
If both the polygons are similar,
[tex]\frac{3}{7.5}=\frac{5}{12.5}[/tex]
[tex]\frac{1}{2.5}=\frac{1}{2.5}[/tex]
Since, sides are proportional,
Both the polygons are similar.
Option (2)
If the given triangles are similar,
Ratio of the sides of both the triangles will be proportional,
[tex]\frac{18}{8}= \frac{24}{15}[/tex]
[tex]\frac{19}{4}=\frac{8}{5}[/tex]
But [tex]\frac{19}{4}\neq \frac{8}{5}[/tex]
Therefore, triangles are not similar.
Option (3)
If both the rectangles are similar,
[tex]\frac{22}{13.75}=\frac{16}{10}[/tex]
1.6 = 1.6
True.
Therefore, both the rectangles are similar.
Option (4)
If both the triangles are similar,
[tex]\frac{8}{5}=\frac{7}{5}[/tex]
1.6 = 1.2
But 1.6 ≠ 1.2
Therefore, these triangles are not similar.

Determine whether the representation is proportional. y = -9x
Answers
Answer:
Yes, they are
Step-by-step explanation:
y = -9x
Here y∝ x
Where -9 is constant of proportionality
If "y" increases by factor of 2, then "x" will also increases by factor of 2. Hence, y and x are " directly proportional" to each other.

Answer:
(b) 13.5
Step-by-step explanation:
The upper vertex would be ...
3/2(3, 3) = (4.5, 4.5)
and the right vertex would be ...
3/2(4, 0) = (6, 0).
The base of the larger triangle would be 6, and its height would be 4.5. Then the area is ...
A = (1/2)bh
A = (1/2)(6)(4.5) = 13.5 . . . area of dilated triangle

A person traveling 60 feet per second is traveling how fast, in miles per hour?
Answers
Answer:21,600 feet per hour
Step-by-step explanation:
60*60=360 (multiplying the distance traveled per second by the number of seconds in a minute to get how far the person traveled in a minute)
360*60=21,600 (multiplying the distance travels in a minute by the number of minutes in an hour to find the total distance traveled in an hour)
Write an equation of the line in slope intercept form
Answers
Answer: y = x + 2 OR f(x) = x + 2
Step-by-step explanation:
Calculating slope:
Remember rise over run; when going from one point to another point, in this case from (-3, -1) to (0,2), locate the distance moved in the x and y directions. This scenario moves 3 up and 3 right, meaning a positive slope of one. However, if the line was directed left, your slope would be negative.
Finding y-intercept:
Where does the line intersect the y-axis and have a x-value of 0? This is your y-intercept --> (0,2).
Write Equation:
y = mx +b
y = 1x + 2
y = x + 2 (your final answer)
Given the fallowing equation, solve for x
y=mx+b
A. x=m(y-b)
B. x=y-m/b
C. x=y-b/m
D. x=b(y+m)

Rachel has 2/3 pound of snack mix. She eats 5/12 of the snack mix. How much of the snack mix did Rachel eat?
Answers
Answer: Racheal ate [tex]\dfrac{5}{18}[/tex] of the snack mix.
Step-by-step explanation:
Given : Rachel has [tex]\dfrac23[/tex] pound of snack mix..
If she ate [tex]\dfrac5{12}[/tex] of the snack mix.
Then, Quantity of snack mix eaten by Rachel = [tex]\dfrac5{12}\times\dfrac23[/tex]
[tex]=\dfrac56\times\dfrac13\\\\=\dfrac{5}{18}[/tex]
Hence, Racheal ate [tex]\dfrac{5}{18}[/tex] of the snack mix.

Austin has $75 to spend on sporting goods. He wants to buy a soccer ball for $12 and spend the rest of the
money on soccer shorts. Each pair of soccer shorts costs $19. Which inequality can be used to find s, the
number of pairs of soccer shorts he can buy?
a. 12 + 195 $ 75
c. 19 + 12s < 75
b. 12 +195 2 75
d. 19 + 12s 275
Answers
Answer:
s = 3 He can only but up to 3 pairs of shorts, with 3 dollars left over.
Answer is 12 + 3s <= 75
Step-by-step explanation:
$75 - $12 = $63
$63 / $19 = $3.3157894 about 3
$3 * $19 = $57
$57 + $12 = $69
$72 - $69 = $3

Robin baked 702 cookies.He sold them in boxes of 18. After selling all of the boxes of cookies for the same amount each, he earned $136.50.what was the cost of one box of cookies
Answers
Answer:
cost of a box is $3.5
Step-by-step explanation:
given data
sold box = 18
earned = $136.50
solution
we consider here number of boxes of cookies is x
and
for we get Tyler sold cookies box so number of boxes we divide 702 cookies among 18 is
Tyler sold = [tex]\frac{702}{18}[/tex]
Tyler sold = 39 boxes
and
now we consider here y as cost of each box of cookies,
so for cost or sale price of the cookie boxes here we divided 136.50 dollars among 39 boxes
so
cost of each box = [tex]\frac{136.5}{39}[/tex]
cost of each box = 3.5
Thus, the cost of each box was 3.5

Answers
Answer:
1/10
Step-by-step explanation:
Answer:
t = 1
Step-by-step explanation:
When you cross multiply the equation becomes:
10(t+8)=10(9)
Now, solve for t.
10(t-8) = 10(9)
10t+80= 90
-80 -80
10t÷10 = 10÷10
t = 1
