Emir and his family ordered a meal that cost $50. Emir paid 8% sales tax and left an 18% tip on $50. What was the total cost?
Answer:
$63.00
Step-by-step explanation:
Your first step is to change the percents into fractions, you do this by moving the decimal point two times to the left.
Your equations look like this:
Tip equation: .18 * 50 = $9.00
Tax equation: .08 * 50 = $4.00
Then you just add them all up to get the total, and you get,
9+4+50 = 63

Answer: In the Instance that she downloads 45 songs, she would pay $40.75. The equation for s songs in one month would be
Money = 7 + s(0.75)
Well, since the time span is a month we can say M is money and n is the amount of months she listens. since this is one month we know N equals 1.
So M = 7n + s(0.75)
7 being the monthly fee, n being the amount of months using the service, s being the amount of songs downloaded, and 0.75 being the cost of every song downloaded.

John plans to make a rectangular garden plot with a length of 2x + 3 feet and a width of x + 2 feet.
- What is the perimeter of the garden?
Answer: 6x+10 ft
Step-by-step explanation: To find the perimeter, all you have to do is add up all the sides. So that would be x+2+x+2+2x+3+2x+3. That is 2x+4+4x+6. And the final answer is 6x+10.

other. Which of the following is the measure of 21?
(1) 51
(2) 64
(3) 72
(4) 102
will give brainliest asap!
Given the diagram given where lines n and p are parallel, and transversals r and s are perpendicular, the measure of angle 1 is: [tex]\mathbf{1) 51^{\circ}}[/tex]
The angle measure where two perpendicular lines intersect each other equals 90 degrees.
Therefore, the angle formed as shown in the figure attached, where transversals r and s meet = 90 degrees.
Since lines n and p are parallel lines, therefore:
[tex]m \angle 1 + 90 = 141[/tex] (alternate interior angles are equal)
Subtract 90 from each side[tex]m \angle 1 = 141 - 90\\\\\mathbf{m \angle 1 = 51^{\circ}}[/tex]
Therefore, given the diagram given where lines n and p are parallel, and transversals r and s are perpendicular, the measure of angle 1 is: [tex]\mathbf{1) 51^{\circ}}[/tex]

Tantasic charges a reservation fee of 20$ and $1 per minute in a tanning bed. Bettersun charges no reservation fee but charges 2$ per minute. How many minutes will the price be the same
Answer:
The indifference point is 20 minutes
Step-by-step explanation:
Giving the following information:
Tantasic:
Reservation fee of 20$ and $1 per minute
Bettersun:
2$ per minute.
First, we need to structure both total cost formulas:
Tantasic= 20 + 1x
Bettersun= 2x
x= number of minutes
Now, we equal both formulas and isolate x:
20 + 1x = 2x
20 = 1x
20= x
The indifference point is 20 minutes
What is the boiling point of salty ocean water?
Answer: approximately 105.7°C
Step-by-step explanation:
Seawater of 35 psu has a specific heat of 0.932 compared with 1.000 for pure water. Pure water freezes at 0 °C and boils at 100 °C (212 °F) under normal pressure conditions. When salt is added, the freezing point is lowered and the boiling point is raised. Therefore, we can tell that salt increases the boiling temperature, but not by very much. If you add 3 grams of salt to 100 grams (or mL) of water, instead of boiling at 100° C, it'll boil at 100.5° C.
And I'm not sure about the ocean water because the expected range is too wide and various, so maybe I guess the boiling point of salty ocean water would be about 105.7°C?

The sum of two numbers is 45. The smaller number is 17 less than the larger number. What are the numbers ?
Answer:
small number is 14
Larger number is 31
Step-by-step explanation:
Let x = one number
Let y = the second number
x + y = 45
x = y - 17
Put y - 17 into the top equation for x
y - 17 + y = 45
2y - 17 = 45 Add 17 to both sides
2y = 45 + 17
2y = 62 Divide by 2
y = 62/2
y = 31
Brianna wants to use a pontoon boat on Saturday at the lake. She has exactly
$200 to spend on the boat rental. The rental is $30 an hour plus a $80 deposit.
How many hours can she rent the pontoon boat for? Create and solve an
equation for this situation.
Answer:
Step-by-step explanation:
She has 200
80 deposit - 200= 120 left to spend
80+30h=200
If she has 120 left to spend at 30 hr, she could have the boat for 4 hrs
80+30h=200 subtract 80 from both sides
30h=120 divide by the 30
h=4

Can someone help me with this.
Answer:
1. y = -4
2. y = -0.73 (rounded; it's a repeating decimal and the 3 goes on. -0.7333333, and so on)
3. y = 24
4. c = -13.5
Step-by-step explanation:
30+7y=-2y-6
You want to get the y all by itself. So in order to do that you must combine the like terms from both sides. (so you'll combine the values with a variable, in this case y, and then you will combine the numbers without a variable.)
So, first, get the y's on the same side.
30+7y = -2y-6
Because 2 is negative "-2y", in order to cancel it out you have to ADD 2y to both sides.
30+(7y+2y)= -6
30+9y=-6
Remember, your goal is to get y by itself. So in order to do that, you have to get rid of the solo number on the same side, which is 30. Therefore, you must subtract 30 from BOTH SIDES.
9y= (-6 - 30)
Remember, when you're subtracting with negatives. The rule is: KEEP IT, SWITCH IT, SWITCH IT.
Keep the -6.
Switch the - to a +
And switch the positive thirty to a negative 30.
9y= -6 + (-30)
9y = -36
You want the y alone, so you have to cancel out the multiplication by its recipriocal (or opposite). The opposite of multiplication is division. So you must divide both sides by 9.
y= -36 ÷ 9
y= -4
__________________________
4(3y+4.1)=7.6
Use the distributive property and multiply the 4 (which is outside of the partenthesis) by what's inside of the parenthesis (3y+4.1).
4(3y+4.1):
4 x 3y = 12y
4 x 4.1 = 16.4
12y+16.4 = 7.6
Subtract 16.4 from both sides
12y = -8.8
Divide both sides by 12 to get the y by itself
y= -0.73 (repeating)
__________________________
3(y+1) = 4y-21
This is similar to the last problem. You must use the distributive property and multiply what's outside of the parenthesis by what's inside of the parenthesis.
3 x y = 3y
3 x 1 = 3
Rewrite the equation
3y+3 = 4y-21
Now this problem is similar to the very first problem
You need y by itself. So subtract 3y from both sides
3=(4y-3y)-21
3= 1y-21
Add 21 to both sides to get y by itself
24=1y
y=24
__________________________
3(2c+5) = 4(c-3)
This is just like the last two problems, you must use the distributive property.
3 x 2c = 6c
3 x 5 = 15
Rewrite equation.
6c+15 = 4(c-3)
Now you have to use the distrubtive property for 4(c-3)
4 x c = 4c
4 x (-3) = -12
Rewrite
6c + 15 = 4c - 12
Subtract both sides by 4c
(6c-4c) + 15 = -12
2c + 15 = -12
Subtract by 15 from both sides.
2c = -27
Divide both sides by 2, in order to get c by itself
c = -27 ÷ 2
c = -13.5
