Answer:
x=35
y=145
z=25
Step-by-step explanation:
(do first)x:
55 + 90 = 145
180-145=35
(do last)y:
25+10=35
180-35=145
(do second)z:
65+90=155
180-155=25
Answer:
x = 35, y = 145, z = 25
Step-by-step explanation:
All triangles' angles have a sum of 180°. Because we know this, we can solve the first triangle easily.
180 = x + 90 + 55
180 = x + 145
35 = x
Angles x and y are what we call suplementary angles. This means they have a sum of 180°.
180 = 35 + y
145 = y
Once again, we know that triangles have a sum of 180°. So the next triangle should now be easy to solve.
180 = 10 + 145 + z
180 = 155 + z
25 = z

Tammy purchased a prepaid phone card for $15. Long distance calls cost 18 cents a minute using this card. Tammy used her card only once to make a long
distance call. If the remaining credit on her card is $6.72, how many minutes did her call last?
Answer:
46 minutes
Step-by-step explanation:
Sorry about not answering your question sooner, but here is your answer:
In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left ver after the call:
15 - 6.72 = 8.28
Then, we divide this number by 0.18:
8.28 / 0.18 = 46
So, Tammy's call lasted 46 minutes
Hope this helps :)
Find the measure of this angle, and explain your answer.
Answer:
50
Step-by-step explanation:
180 - 90+40 = 50
Answer:
Answer: 50 degrees
Step-by-step explanation:
important things to know:the square in the bottom right means 90°all angles in a triangle add up to 180°using this knowledge, you can make the following equation:
90 + 40 + x = 180
130 + x = 180
now subtract 130 from both sides.
x = 180 - 130
x = 50°

It takes a boat 3 hours to travel 45 miles downstream and 4 hours to travel 44 miles upstream.
What is the speed of the boat in still water?
The boat travels at...
miles per hour in still water.
What is the speed of the current of the river?
The speed of the current is...
miles per hour.
Answer:
2 miles per hour
Step-by-step explanation:
We use the distance formula. D = r * t
45/3 = 15 mph | Trip 1 |
44/4= 11mph | Trip 2 |
15-11 = 4 mph difference traveling upstream or downstream. Thus the speed of the current is 2 miles per hour.

Answer:
(f o g) = -5x+22
Step-by-step explanation:
f o g basically means f(g(x))
So:
f(g(x)) = -5(x-4)+2
f(g(x)) = -5x+20+2
f(g(x)) = -5x+22
Therefore: (f o g) = -5x+22
This is called function composition. Basically, the output of g(x) goes into the input of f(x).

Suppose that the volume of water in the rain barrel
decreased by 4 5/8 gallons in four minutes. What will be
the change in the volume of water after one minute?
Answer:
Step-by-step explanation:
A unit rate is a rate for one of something.
It is written as a ratio with a denominator of one.
The change in the volume of water in one minute is 1 5/32 gallons.
What is a unit rate?A unit rate is a rate for one of something.
It is written as a ratio with a denominator of one.
We have,
4 5/8 gallons decrease in 4 minutes.
This can be written as:
4 5/8 gallons = 4 minutes
37/8 gallons = 4 minutes
Dividing both sides by 4 we get,
(37/8) / 4 = 4/4 minutes
37/(8x4) = 1 minute
37/32 = 1 minute
1 5/32 gallons = 1 minute
Thus the change in the volume of water in one minute is 1 5/32 gallons.

The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Josh is comparing the cost of having his car wash plus filling up his tank with gas at each business. How many gallons of gas would he need to purchase for the cost to be the same at each car wash?
Answer:
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash
Step-by-step explanation:
We need to model both car wash's costs. The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. If x is the number of gallons of unleaded gasoline. the total charges of this store are:
C1=15+2.5*x
The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Following the same procedure, their costs are:
C2=10+2.75*x
Josh wants to know how many gallons of gas will make both businesses charge the same. Equating both equations:
15+2.5*x=10+2.75*x
Simplifying:
-0.25x=-5
Solving:
x=-5/(-0.25)=20
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash

Hannah wants to buy a $540 camera. She can save $40 each week from her paycheck. However, before Hannah can buy the camera, she must give her brother $60 that she owes him. For how many weeks will Hannah need to save before she can pay back her brother and buy the camera?
Answer:
w = 12
Step-by-step explanation:
Create formula:
540 = 40w - 60 where 540 is the cost of the camera, 40 is the amount saved, w is the number of weeks, 60 is the amount owed
Solve for w
540 = 40w - 60: subtract 60
480 = 40w: divide by 40
w = 12
