A family eats at a restaurant. The bill was $54. The family leaves a tip and spends $60 total. How much was the tip as a perentage of the bill? (round to the nearest whole percent)
Answer:
11%
Step-by-step explanation:
60 - 54 = $6 The tip is $6 since they were meant to pay $54 but gave $6 extra.
The bill is $54.
6/54 = 0.1 recurring
0.1 × 100 = 11.1%
11% is the percentage.
I hope that helps!! ^-^
Which set of ordered pairs represents y as a function of x?
Answer:
D is the correct answer
Explanation:
the following function satisfies each output to its input for the set D
f(x)=x/2
let's check each pair:
0/2=0
-1/2=-0.5
-2/2=-1
-3/2=-1.5
-4/2=-2
the reason why A, B, and C can't be pairs of inputs and outputs x and y it's because a variable x can't have more than one y (that's a behaviour of an equation not a function!)
- in A x=-1 | y=2, -2 and this wrong
- in B x=3 | y=9, 16 and this wrong
- in C x=0 | y=0, 1 and this wrong

EQ: How do you use elimination to solve a system of
equations?
Answer:
Step-by-step explanation:
when you use elimination you want to set two of the terms, in the different equations, equal to each other and then subtract the entire equation from the other, so that the two terms cancel out. Then you have an equation with one less variable in it. :)
Choose the graph of the system of equations.

Find the vertex for the following functions.
f(x) = -2x2 + 8x + 3
A. (11,2)
B.(2,11)
C.(0,0)
Answer:
Vertex is (2, 11)
Step-by-step explanation:
Call the vertex (h, k)
A quick way to find h is use the formula h = -b/2a
In your case, h = -8/-4 = 2
Now, to find k.
k = f(2) = -2(2)^2 +8(2) + 3
= -8 + 16 + 3
= 11
Vertex is (2, 11)

The recycling center collected 48,000 ounces of
aluminum cans last week. How many tons of
aluminum did the recycling center collect?
Answer: 1.5 tons
Step-by-step explanation:
Given
The recycling center collected 48,000 ounces of aluminum can
An ounce is the unit of weight and it can be expressed in tons as
[tex]1\ \text{ounce}=3.125\times 10^{-5}\ \text{tons}[/tex]
[tex]\therefore 48,000\ \text{ounces} \equiv\ 3.125\times 10^{-5}\times 48,000=1.5\ \text{tons}[/tex]

A paved walkway around a garden has an outer diameter of 80 ft and an inner diameter of 40 ft. A diagram is shown below.
What is the approximate area of the paved walkway?
Given:
Outer diameter = D = 80 ftInner diameter = d = 40 ftSo,
Outer radius = R = D/2
=> R = (80 ft)/2
=> R = 40 ft
Inner radius = r = d/2
=> r = (40 ft)/2
=> r = 20 ft
Area of paved pathway = πR² - πr²
= π(R² - r²)
= π(R + r)(R - r)
= π(40 + 20)(40 - 20) ft²
= π(60)(20) ft²
= 3.14 * 1200 ft²
= 3768 ft²

HELP ASAP. please show work. the plane of a room in the picture. the scale is 2 inches: 6 feet. what is the actual length, width , and area?
Answer:
Actual Length: 27 feet - Actual Width: 15 feet - Actual Area: 405 feet
Step-by-step explanation:
First, to find the length, you have to divide 9 by 2 to get 4.5 and then multiply it by 6 to get the actual amount of feet. Then you divide 5 by 2 and multiply the quotient by 6 to get the actual width. Then, you take the actual length (27 feet) and multiply it by the actual width (15 feet) and you get an area of 405 feet

Answer:
y = 6/7x - 37/7
Step-by-step explanation:
m = 6/7
(5, -1)
y - y1 = m(x - x1)
y + 1 = 6/7(x - 5)
y + 1 = 6/7x - 30/7
y = 6/7x - 37/7
Answer:
Step-by-step explanation:
Start by the point-slope form and given slope = 6/7 and point (5, -1)
(y-(-1)) / (x-5) = 6/7
7(y+1) = 6(x-5)
7y = 6x - 37
y = 6x/7 - 5 2/7
which is the answer in slope-intercept form

Answer:
a.
2x+4x+3x=180 sum of interior angle of the triangle is 180
9x=180
x=180/9=20
b.
x-20+x+10+x-20=180sum of interior angle of the triangle is 180
3x-30=180
3x=180+30
x=210/3=70
c.x+10+x+20+x=180 linear pair
3x+30=180
3x=180-30
x=150/3=50
Answer:
A: x=20
Step-by-step explanation:
angles in a triangle always equal 180° so knowing this 2x+3x+4x=180
9x=180
9x÷9=x
180÷9=20
20=c/5

Step-by-step explanation:
BC^2 + DC^2 = AC^2
6^2 + 4^2 =AC^2
36 + 16 = AC^2
52=AC^2
√52=AC

Which expression models the phrase "Wally mowed two more lawns than he mowed last week"? n + 2 n minus 2 2 minus n 2 n
Given:
The phrase is "Wally mowed two more lawns than he mowed last week".
To find:
The expression that models the given phrase.
Solution:
Let the number of lawns mowed by Wally last week be n.
We know that, we use plus sign "+" for "more".
If Wally mowed two more lawns than he mowed last week, then the lawns mowed by the Wally this week is the sum of n and 2.
Lawns mowed this week = [tex]n+2[/tex]
The required expression for the phrase "Wally mowed two more lawns than he mowed last week" is n+2.
Therefore, the correct option is A.

15= 2x
x= 7.5
2. adjacent angles equal 180
(2m+8)+(3m-4)= 180
5m+4= 180
5m= 176
m= 35.2
