a) The pairs of proportional triangle is
AB and YZ,
AC and XY,
BC and XZ
b) The fraction of side is
YZ / AB = XY / AC= XZ / BC = 3/4.
c) Yes the similarity of Triangle.
What is Similarity?Similar triangles are triangles that have the same shape but differ in size. Similar items include all equilateral triangles and squares with any side length. In other words, if two triangles are identical, their corresponding angles and sides are congruent and in equal proportion. The " sign here denotes the resemblance of triangles.
In Triangle ABC and YZX
a) So, the pairs of proportional triangle is
AB and YZ,
AC and XY,
BC and XZ
b) The fractions with your side pairs is
YZ / AB = 30 / 40 = 3/4
XY / AC = 37.5 / 50 = 3/4
XZ / BC = 45/ 60 = 3/4.
c) As, the ratio of sides are proportion.
So, by SSS similarity criteria the triangles are similar.

A kite has A = 120 cm2 and d1 = 16 cm. Identify the length of d2.
Answer:
d₂ = 15 cm
Step-by-step explanation:
The area (A) of a kite is calculated as
A = [tex]\frac{1}{2}[/tex] d₁d₂
Here A = 120, d₁ = 16 , then
[tex]\frac{1}{2}[/tex] × 16 × d₂ = 120
8d₂ = 120 ( divide both sides by 8 )
d₂ = 15 cm

John travels 16m ^2 +100 miles. /since he can only travel 8m +10 mph, it takes him 2m hours to make the trip. Solve for m
Answer:
m = 5
Step-by-step explanation:
distance traveled D= 16m^2+100 miles
speed, S= 8m+10 mph
time taken, T = 2m hours
We know that D = S×T
⇒ 16m^2+100 = (8m+10)× 2m
⇒ 16m^2+100 = 16m^2+ 20m
⇒ 20m = 100
⇒ m = 5
Therefore, the value of m is 5

Lindsey bought a picnic basket originally priced at $40 but on sale for 50% off. After 10% sales tax, what was the total cost?
Answer:
$30
Step-by-step explanation:
Given data
Origianal price= $40
discount= 50%
Tax= 10%
Let us find the amount of the discount and tax
Discount
=50/100*40
=0.5*40
=$20
Tax
=10/100*40
=0.1*40
=$4
Hence the total cost is
=40-20+10
=$30

16. A radioactive isotope has a half-life of 13 hours. Find the amount of the isotope left from a 400-milligram
sample after 65 hours. If necessary, round your answer to the nearest thousandth.
a. 25 mg
c. 0.049 mg
b. 7.692 mg
d. 12.5 mg
Please help. I only see answers for 52 hours
Answer:
Without the math: 65 hours is 5 half-lives
13 hrs = 1/2
26 hrs = 1/4
39 hrs = 1/8
65 hrs = 1/32
(1/2)^5 = 1/32
400 mg / 32 = 12.5 mg that is, after 5 half-lives

Emma noticed that the new admission fee for a zoo is 65% more than last year’s fee. If f represents last year’s fee, which of the following expressions represent the new admission fee? Select all that apply.
Answer: 1.65f
Step-by-step explanation:
Last year's admission fee = f
Percentage Increase in the admission fee = 65%
New admission fee will be the addition of last year's admission fee and the increase in the admission fee. This will be:
= f + (65% × f)
= f + (65/100 × f)
= f + (0.65 × f)
= f + 0.65f
= 1.65f
The new admission fee is 1.65f
Kelli Rae invested $220,000 in a savings account with simple interest. After 10 years, Kelli Rae had $250,000. What is the interest rate on this account?
Answer:
Interest rate = 1.363% (Approx.)
Step-by-step explanation:
Given:
Amount invested P = $220,000
Amount after 10 year = $250,000
Number of year = 10 year
Find:
Interest rate
Computation:
A = P + I
Amount of interest = $250,000 - $220,000
⇒ Amount of interest = $30,000
Amount of interest = PRT
⇒ 30,000 = (220,000)(R)(10)
⇒ 30,000 = (2,200,000)(R)
⇒ R = 0.013636
Interest rate = 1.363% (Approx.)

Given data
Total amount=$30
Drink = 1/5*30= $6
Ticket= 45% of 30

=0.45*30
=$13.5
The remainder is for food
=30-6-13.5
=$10.5
Given that x^6 = 64, which of the following could be the value of 9x^2 + 3x ?
Answer:
42,-42
Step-by-step explanation:
We first solve for x from x^6 = 64, by taking the root of both sides, and we get x = 2,-2
We then plug in both of the x values and get 42,-42
PS: That should be the right answer but you didn't include the possible answers, and I somehow also got 30 when plugging in -2, but just try it yourself to be safe.
