Kevin delivers 30newspapers in 2 hours. How many newspapers can be
deliver in 3 hours? Find the unit rate first to solve this two-step problem
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:
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)

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
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

Step-by-step explanation:
HELP !!!! A rental car company charges $61 per day to rent a car and $0.12 for every mile driven. Nathan wants to rent a car, knowing that: • He plans to drive 400 miles. • He has at most $170 to spend.
Answer:
2 days
Step-by-step explanation:
he plans to drive 400 miles, so the cost of his miles will 400*0.12=48
his total budget is 170, so subtract 48 from that
170-48=122
the rental company charges 61 per day and he has 122 after subtracting the cost of his miles, so he will have 122/61 days to drive 400 miles
122/61=2
Knowing the charge per day and per mile driven of a rental car company, we want to see if Nathan has enough money to travel. We will see that Nathan has enough money to rent the car for two days and travel the 400 miles he plans to.
Now let's see how to solve the problem.
We know that the rental company charges $61 per day plus $0.12 per mile driven.
Assuming that Natan will only rent the car for one day, if he drives for x miles the total cost is:
C(x) = $61 + $0.12*x
Now, we know that Natan wants to drive 400 miles ( in total) and he can spend, at most, $170
So let's see if he can do it, we just evaluate the cost equation in x = 400
C(400) = $61 + $0.12*400 = $109
This even means that he could rent the car for another day, because adding $61 the cost becomes:
$109 + $61 = $170

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?
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
