Answer:
$4.61
Step-by-step explanation:
To calculate a tip of 20%, you would perform the following:
$92.18 * 0.20 = $18.436
Similarly, for a tip of 15%:
$92.18 * 0.15 = $13.827
The difference would just be subtracting the two tip amounts from each other!
$18.436 - $13.827 = $4.609
Then you round to the nearest cent.
$4.609 ≈ $4.61

The number of children at the library was 3 times the number adults. The total number of people at the library was 48. How many children were at the library
A 12
B 24
C 32
D 36
Answer:
D 36
Step-by-step explanation:
Write the information algebraically
c = 3a
c + a = 48
c = children, a = adults
In the second sentence (in bold), we can replace c with 3a
c + a = 48 → 3a + a = 48
Simplify
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
We can then substitute or plug in a = 12 into the original equation:
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)

2) A pool is being filled with a hose. The equation y=12x represents the relationship between
the number of gallons of water in the pool (y) and the number of minutes the water runs (X). If
this relationship is represented on a graph, which ordered pair would not lie on the line?
NEED HELPS ASAP PLS AND THANK U
Answer:
D)
Step-by-step explanation:
y = 12x.
A) x=8, so that y = 12(8) = 96. It's on the line
B) x = 10, so that y = 12(10) = 120. It's on the line
C) x = 15, so that y = 15(12) = 180. It's on the line
D) x = 18, so that y = 18(12) = 216, not equal to 206. So, the point is not on the line.
Three consecutive integers have a sum of 45. Find the integers.
Answer:
14,15,16
Step-by-step explanation:
Call n the first integer so you get:
n+(n+1)+(n+2)=45
3n+3=45
3n=42
n=14
The integers are:
14,15,16
Answer:
14,15,16
Step-by-step explanation:
Let the integers be x, (x+1),(x+2)
So,
x+(x+1)+(x+2)=45
x+x+1+x+2=45
3x+3=45
3x=45-3
x= 42/3
x=14
Now put the value.
x= 14(x+1)= 14+1= 15(x+2)=14+2= 16Now, Add these integers
you'll get
14+15+16=45

Answer: About 317.4 oz or 19 lbs! Pls Brainly Thx :D
Answer:
D) 19.8 lbs
Explanation:
1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.
1kg is also equal to 2.205 lbs. 9*2.205=19.8416
9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system
a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.
This leaves us with 19.8 lbs

Evaluate f(x)=2x+8 when x=−2, x=0, and x=5.
f ^− 1 ( x ) = x/2 − 4
That is the inverse
The value of the function, for x=-2 is 4.
The given function is f(x)=2x+8.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
When x=-2, we get
f(-2)=2(-2)+8
=4
When x=0, we get
f(0)=2(0)+8
= 8
When x=5, we get
f(5)=2(5)+8
= 18
Therefore, the value of the function, for x=-2 is 4.

Answer:
y = 8
Step-by-step explanation:
If the variation is direct, any multiplier of the x-value will also multiply the y-value.
old value × -1 = new value
x: 4 × -1 = -4
y: -8 × -1 = 8
The new value of y is 8.
Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they charged a total of $950. What was the rate charged per hour by each mechanic if the sum of the two rates was $125 per hour?
Answer:
First mechanic: $65.
Second mechanic: $60.
Step-by-step explanation:
Let the rates be x for the first mechanic and y for the second.
x + y = 125
10x + 5y = 950
Multiply first equation by - 5
-5x - 5y = -625
Adding the last 2 equations:
5x = 325
x = 65
y = 125-65 = 60 .

Step-by-step explanation:
Great Pyramid has 2^21 blocks
2^21 = 2097152, so
2097152 blocks
Blocks weigh 2^11 each
2^11 - 2048, so
2048 kg per block

Step-by-step explanation:
More than 2,300,000 limestone and granite blocks were pushed, pulled, and dragged into place on the Great Pyramid. The average weight of a block is about 2.3 metric tons (2.5 tons).
How much is that? Well, you can think of it in terms of refrigerators. An average refrigerator weighs about 91 kg. If 1 metric ton = 1,000 kg, how many refrigerators equal a 2.3-metric ton block?
