Answer:
19 Dollars
Step-by-step explanation:
Discount means that a certain percentage of the price is being deducted from the final price. So, it this case, we first have to find 5% of 20. 5% of 20 is 1 because 20 * .05 is one. Then, we just have to deduct 1 dollar from 20 dollars, making it 19 dollars.

deliver in 3 hours? Find the unit rate first to solve this two-step problem
Answers
Answer:
45 newspapers can be delivered in 3 hours.
Step-by-step explanation:
Given that,
Kevin delivers 30 newspapers in 2 hours.
We need to find how many newspapers can be delivered in 3 hours.
2 hours = 30 newspaper
1 hour = 15 newspaper
In 3 hours,
3 hour = 15 × 3 newspaper
= 45 newspapers
Hence, 45 newspapers can be delivered in 3 hours.

Answer:
x = 3.53 ( this may not be the exact number because my factoring is rusty)
Step-by-step explanation:
7x/(7x + 3) = (20x - 4)/(22x - 2)
7x(22x - 2) = (20x - 4)(7x + 3)
154x² - 14x = 140x² + 60x -28x -12
combine like terms & reduce:
14x² -46x - 12 = 0
divide by 2 to simplify:
7x² - 23x - 6 = 0
factor:
(7x + 1.7)(x - 3.53) = 0
x = 3.53

The perimeter of a rectangle is 44 meters and the length is 10 meters more than twice the width. Find the dimensions.
A: 18 meters and 4 meters
B: 6 meters and 9 meters
C: 5 meters and 9 meters
D: 6 meters and 16 meters
Answers
Answer:
Width of rectangle = 4 meter
Length of rectangle = 18 meter
Step-by-step explanation:
Given:
Perimeter of rectangle = 44 m
Assume;
Width of rectangle = a
Length of rectangle = 2a + 10
Find:
Length and width
Computation:
Perimeter of rectangle = 2[l + b]
2[a + 2a + 10] = 44
3a + 10 = 22
3a = 12
a = 4
So,
Width of rectangle = a = 4 meter
Length of rectangle = 2a + 10 = 18 meter

Answer:
Triangle a: 44.7°
Triangle b: 30.5°
Triangle c: 67.4°
Triangle d: 56.6°
Step-by-step explanation:
Recall: SOHCAHTOA
a. Reference angle = [tex] \theta [/tex]
Opposite = 19
Hypotenuse = 27
Apply SOH:
[tex] sin(\theta) = \frac{Opp}{Hyp} [/tex]
[tex] sin(\theta) = \frac{19}{27} [/tex]
[tex] \theta = sin^{-1}(\frac{19}{27}) [/tex]
[tex] \theta = 44.7 degrees [/tex] (nearest tenth)
b. Reference angle = [tex] \theta [/tex]
Opposite = 33
Adjacent = 56
Apply TOA:
[tex] tan(\theta) = \frac{Opp}{Adj} [/tex]
[tex] tan(\theta) = \frac{33}{56} [/tex]
[tex] \theta = tan^{-1}(\frac{33}{56}) [/tex]
[tex] \theta = 30.5 degrees [/tex] (nearest tenth)
c. Reference angle = [tex] \theta [/tex]
Opposite = 12
Adjacent = 5
Apply TOA:
[tex] tan(\theta) = \frac{Opp}{Adj} [/tex]
[tex] tan(\theta) = \frac{12}{5} [/tex]
[tex] \theta = tan^{-1}(\frac{12}{5}) [/tex]
[tex] \theta = 67.4 degrees [/tex] (nearest tenth)
d. Reference angle = [tex] \theta [/tex]
Hypotenuse = 20
Adjacent = 11
Apply CAH:
[tex] cos(\theta) = \frac{Adj}{Hyp} [/tex]
[tex] cos(\theta) = \frac{11}{20} [/tex]
[tex] \theta = cos^{-1}(\frac{11}{20}) [/tex]
[tex] \theta = 56.6 degrees [/tex] (nearest tenth)

You will divide both sides by -10
This will cancel the -10 on right side and get

e will then equal 0.01 (a negative divided by a negative with result in a positive number)
e=0.01

7 Romeo and Juliet first saw each other when they were 270 feet apart.
Romeo began running toward Juliet at a rate of 16 ft/s. At the same
moment, Juliet began running toward Romeo at a rate of 14 ft/s.
A. How many seconds after they started running will they meet?
B. How far will Romeo have run then?
Answers
Answer:
A: 9 seconds
B: 144 ft.
Step-by-step explanation:
A:
Let t = no. of seconds for them to meet
When they meet the sum of their distances is 270 ft, dist = rate * time
16t + 14t = 270
30t = 270
t = 270/30
t = 9 seconds
B:
He ran 9 sec at 16 ft/sec, therefore:
9 * 16 = 144 ft
B: 144
I’m pretty sure that’s the answers
