20. Isosceles trapezoid LMNO has vertices L(-4,-3), M(-4,0), N(-2, 1),and O(-2,-4). If the figure is
dilated with the center at the origin and with a scale factor of 1.5, what is the length of L'M' of the
dilated isosceles trapezoid?
Answers
Answer:
L’M’ = 4.5 units
Step-by-step explanation:
We start by getting the dilated coordinates
we specifically work with the points LM
The dilated points can be obtained by multiplying the individual coordinates by 1.5
for L (1.5 * -4 and 1.5 * -3) = L’ (-6, -4.5)
M (-4,0) and ; (1.5 * -4 and 0 * 1.5) = M’ (-6,0)
Now, we can use the distance formula
D = √(y2-y1)^2 + (x2-x1)^2
D = √(0+ 4.5)^2 + (-6+6)^2
D = √(4.5)^2
D = 4.5 units

Suppose a local park is rectangular in shape and has a length of 210 yards and a width of 105 yards. What is the length of the diagonal of the park? Round your answer to the nearest hundredth of a yard.
Answers
Answer:
234.784 ~ 235
Step-by-step explanation:
One side = 210
other side = 105
a2+b2 = c2
210 ^2 + 105 ^2 = c2
55125 = c ^2
c = [tex]\sqrt{55125}[/tex] = 234.784 ~ 235

Question 2: v = 84
Question 3: y = 60
Question 4: w = 496
Question 5: Kyle had $400 to begin with.
Step-by-step explanation:
Question 1 explanation: 12g = 72 ⇒ g = [tex]\frac{72}{12}[/tex] = 6
Question 2 explanation: [tex]\frac{v}{4}[/tex] = 21 ⇒ v = 21 * 4 = 84
Question 3 explanation: [tex]\frac{1}{6}[/tex] y = 10 ⇒ 6 * [tex]\frac{1}{6}[/tex] y = 10 * 6 ⇒ y = 60
Question 4 explanation: w + 376 = 872 ⇒ w = 872 - 376 = 496
Question 5 explanation: K - 85 = 315 ⇒ K = 315 + 85 = 400, so Kyle had $400 originally in his account.

Step-by-step explanation:
Using Pemdas:
3 (1 + 4) / 3 + 4^2
3 (5) / 3 + 4^2
3 (5) / 3 + 16
15 / 3 + 16
Answer:
A
Step-by-step explanation:
First you have to simplify the equation, you should use PEMDAS. This means you first have to simplify the parenthesis. simplify it, multiply 3 by 1 and 4. This makes the equation 3+12/3+4^2. Then following PEMDAS, you simplify the exponent. 4^2 is the same as 4x4 so 4^2 is 16. 3+12/3+16, then you can simplify either side first. 3+12/18, then you simplify the only part left. 15/18. The GCM of this fraction is 3 so you divide both sides by 3. 15/3/18/3. Simplify this to get 5/6.
When you simplify equation A, you get 15/3/6. First simplify 15/3 to get 5. This equation answer is 5/6 which is equal to 5/6 so this is the correct answer.
When you simplify equation B, you get 15/3/8. Simplify 15/3 again and get 5. This equation answer is 5/8 which is not equal to 5/6 so this is not the correct answer.
When you simplify equation C, you get 15/3/16. Simplify 15/3 first and get 5. 5/16 is not equal to 5/6 so this is not the correct answer.
Therefore, Equation A is the correct answer.

Perry used the formula V (t) = 24,450(1-0.13)
to find the value of his car t years after he purchased it.
What does 0.13 represent?
A the price of the new car
B the time of year the car was purchased
the value of the car after t years
a 13% decrease in value each year
Answers
Answer:
D) a 13% decrease in value each year
Step-by-step explanation:
Perry used the formula V (t) = 24,450(1-0.13)^t to find the value of his car t years after he purchased it.
What does 0.13 represent?
The expression given above represents and expression of exponential decrease.
This is represented by the formula
y = a(1 - r)^t
Where
y = Value after time t
a = Initial value
r = Rate of decrease
t = Time
Comparing both expressions
y = a(1 - r)^t = V (t) = 24,450(1-0.13)^t
We can see that:
r = 0.13
This is the rate of decrease.
Converting to Percentage = 0.13 × 100
= 13%
