Answer:
JKLM ~ QRSP, scale factor 0.6ΔABC ~ ΔUVT, scale factor 1.5Step-by-step explanation:
We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.
1. JKLM ~ QRSP
JK : KL : LM : MJ = 20 : 15 : 24 : 25
QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)
The scale factor is 12/20 = 0.6.
__
2. ΔABC ~ ΔUVT
AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6
UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)
The scale factor is 24/16 = 1.5.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of units of orange juice at beginning = 30 units
The number of units purchased = 50 units
Total units = 30 + 50 = 80 units
The number of units at the end = 30 units.
The number of units sold.
= Total units - Units at the end
= 80 - 30
= 50 units.
Thus,
The number of units sold is 50 units.

Kevin earns $12.00 for every 5 story problems he writes. How much would Kevin get for writing 12 problems?
Answers
Answer: $28.80
Step-by-step explanation:
We can start by finding the unit rate. How much money does Kevin earn from writing 1 story problem?
We can find how much Kevin earns from writing 1 story by dividing 12 by 5.
12 ÷ 5 = 2.4.
Therefore, Kevin earns $2.40 for every story he writes.
Now we have to find how much Kevin earns from writing 12 story problems. If Kevin earns $2.40 for every story he writes, then we should mutliply that by 12 to find how much money Kevin earns for writing 12 problems.
2.40 x 12 = 28.8.
In conclusion, Kevin earns $28.80 dollars for writing 12 problems.

Of the last 60 people who went to the cash register at a department store, 15 had BLOND hair,
17 had BLACK hair, 26 had BROWN hair, and 2 had RED hair. Determine the experimental
probability that the next person to come to the cash register has BLOND hair. (answer as
simplified fraction)
Answers
Answer:
[tex]P(Blond) = \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]Total = 60[/tex]
[tex]Blond = 15[/tex]
[tex]Black = 17[/tex]
[tex]Brown = 26[/tex]
[tex]Red = 2[/tex]
Required:
Determine the experimental probability of the next person having blond hair
This is calculated by dividing the number f people having blond hair with the total number of people.
i.e.
[tex]P(Blond) = \frac{Blond}{Total}[/tex]
[tex]P(Blond) = \frac{15}{60}[/tex]
Simplify
[tex]P(Blond) = \frac{1}{4}[/tex]

Given that :
Card numbered from: 500 - 799
The required number of values must meet both conditions 1 and 2
Condition 1 : first of the 3 digits is odd :
500 - 599 = 100
700 - 799 = 100
(100 + 100) = 200 cards
Condition 2: three digits is divisible by 6
{500 - 599} and {700 - 799}
The numbers divisible by 6 are 33

An airplane is currently flying at an altitude of 37,000 feet. The airplane is scheduled to land at an airport 100 miles
away. Find the average angle at which the airplane must descend for landing. Round your answer to the nearest
degree.
Answers
Answer:
4degrees
Step-by-step explanation:
Given the following
Height of the airplane = 37000feet
distance covered on landing = 100miles = 100(5280)
distance covered on landing = 528,000feet
Using the SOH CAH TOA
sin theta = opposite/hyp
sin theta = 37000/528000
sin theta = 37/528
theta = arcsin (37/528)
theta = 4 degrees
Hence average angle at which the airplane must descend for landing is 4degrees

y = 2(x - 8)(x+2)
A. What are the X intercept(s)?
B. What is the Vertext?
C. What is the axis of symmetry?
D. What is the Y intercept?
Answers
Answer:
Step-by-step explanation:
y=2(x-8)(x+2)
The x intercepts occur when y=0, so when x=8 and -2
The vertex is where the equation is at a minimum/maximum in this case (x,y)=(3,-50)
The axis of symmetry occurs between the two roots, 8 and -2 which x=3
The y intercept is the value of y when x=0, in this case (0, -32)

area of this figure.

8 in.
5 in.
12 in.
10 in.
Can anyone help me with this?
Answers
Answer:
528 in.²
Step-by-step explanation:
Surface area of the figure = (surface area of the smaller rectangular prism + surface area of the bigger prism) - area of 1 of the base of the smaller rectangular prism
✔️Surface area of the bigger rectangular prism = 2(WL + HL + HW)
= 2(10*12 + 5*12 + 5*10) = 2(120 + 60 + 50)
= 2(230)
Surface area of bigger rectangular prism = 460 in.²
✔️Surface area of the smaller rectangular prism = 2(WL + HL + HW)
= 2(2*2 + 8*2 + 8*2) = 2(4 + 16 + 16)
= 2(36)
Surface area of smaller rectangular prism = 72 in.²
✔️area of 1 of the base of the smaller rectangular prism = L*W = 2*2 = 4 in.²
✅Surface area of the figure = (460 + 72) - 4
= 532 - 4
= 528 in.²
