Answer: 18.5% of the bill.
Step-by-step explanation:
Since the bill was 42 dollars while the total amount was 49.77, we need to subtract 42 by 49.77.
49.77 - 42 = 7.77.
So the tip was $7.77.
But then we also have to find the tip as a percentage.
So we should do 7.77 divided by 42, because 42 is the original amount.
7.77 ÷ 42 = 0.185, but as a percent you have to move to the left two places. So the decimal is 18.5.
In conclusion, the tip was 18.5% of the bill.
Hope this helps!

the subtraction sign takes over the addition sign
a fun way to remember is when you subtract a negative just take the two subtraction signs and they create and addition sign. when you are adding a negative, think as is you are taking one of the lines away becauze +(-) = negative. and addition plus addition is equal to addition
Answer: 7 + (-3) equals to 4
Step-by-step explanation:You have to start with the number in the parenthesis and the pls sign. A negative multiplied by a positive would give you a negative, so positive 1 multiplied by -3 equals to -3. Now the equation is 7 - 3, and the answer equals to 4.
The top of a ladder slides down a vertical wall at a rate of 0.32 m/s. At the moment when the bottom of the ladder is 8 m from the wall, it slides away from the wall at a rate of 0.6 m/s. How long is the ladder?
Answer:
The length of the ladder = 17 meters(17m)
Step-by-step explanation:
The formula to find the Length of the ladder is given as:
L² = x² + y²
Where L = Length of the Ladder
Let x = 8m
We solve for y
From the above question, we are told that:
The top of a ladder slides down a vertical wall at a rate of 0.32 m/s.
Hence: (-0.32)y = -0.32y
At the moment when the bottom of the ladder is 8 m from the wall, it slides away from the wall at a rate of 0.6 m/s. Hence:
8(0.6) - 0.32y = 0
4.8 = 0.32y
y = 4.8/0.32
y = 15m
Hence:
L² = x² + y²
L² = 8² + 15²
L² = 64 + 225
L² = 289
Square root both sides
L = √289
L = 17m
The length of the ladder = 17 meters(17m)
A store at the mall was closing. Everything in the store was 75% off. If you
wanted to buy a $200 jacket, how much did it actually cost you?
Answer:
50 dollars
Step-by-step explanation:
if everything was 75% off then you are only paying 25% of the original price. so 200 multiplied by 0.25( which is the same as multiplying my 25/100 or 1/4)=50
Answer:
$267
Step-by-step explanation:
75%=200
1%=2.67
100%=267

A road 2 m broad surrounds a square park 4225 m² in area. Find the cost of
marbles each of 25 cm by 8 cm in size on the road at Rs 50 per piece of marble.
Given :
A road 2 m broad surrounds a square park 4225 m² in area.
Size of marble is 25 cm by 8 cm.
Price of each marble is Rs 50.
To Find :
Total cost.
Solution :
Side of square road is :
[tex]A^2 = 4225\ m^2\\\\A = 65\ m[/tex]
Area of road = [tex]4\times 65\times 2 \ m^2=520\ m^2[/tex]
Number of marbles required is :
[tex]N = \dfrac{A}{a}\\\\N = \dfrac{520\times 10^4\ cm^2}{200\ cm^2}\\\\N = 26000[/tex]
It is given that price per marble is Rs 50.
So, total price required is :
[tex]P = Rs \ 50\times 26000 \\\\P = Rs \ 13,00,000[/tex]
Hence, this is the required solution.

HELP
Answer:
8.25 ft & 6.75 ft
Step-by-step explanation:
So we know it's split into two pieces, right? So normally that would be 7.5 ft each. But one is 1.5 ft longer than the other. So as a result, I divided that by 2 to add 0.75 ft to piece one and subtract 0.75 ft from piece two's length. So, the longer piece is 8.25 ft, and the shorter one is 6.75 ft.
Answer:
Solution given:
total length=15foot
splits into 2 pieces
let shorter pieces be x.
we have longer pieces =2x-1.5ft
Now
total length=x+2x-1.5ft
15 ft =3x-1.5ft
15+1.5=3x
x=[tex] \frac{16.5}{3} [/tex]=5.5ft
Now
shorter length: 5.5ft.
longer length:2*5.5-1.5=9.5ft.

(-3s+2t)(4s-t)
Answer:
- 12s² + 11st - 2t²
Step-by-step explanation:
Given
(- 3s + 2t)(4s - t)
Each term in the second factor is multiplied by each term in the first factor, that is
- 3s(4s - t) + 2t(4s - t) ← distribute both parenthesis
= - 12s² + 3st + 8st - 2t² ← collect like terms
= - 12s² + 11st - 2t²

What’s the pair of perpendicular line segments?
Answer:
Two perpendicular segments are segment AB and segment CD
Step-by-step explanation:
The given construction with the straight edge and the compass gives;
1) A straight line CD
2) A line AE from the center of the circle A, to the line CD
3) The circles A and B constructed from the centers A and B respectively
Therefore
Whereby the points A and B are joint by the line AB, we have;
The line passing through the points C and D is the perpendicular bisector of line AB
Therefore, two perpendicular segments are segment AB and the perpendicular bisector of AB which is segment CD

Michael invests $2,600 into a certificate of deposit (cd). If he earns 4.5% interest, how long will it take for him to earn $234 in simple interest?
Answer:
2 years
Step-by-step explanation:
Step one:
Given Information
Principal= $2600
rate = 4.5%
SImple interest = $234
Required
The time T of the investment
Step two:
the expression for simple interest is
[tex]SI= PRT/100[/tex]
substitute
[tex]234= 2600*4.5*T/100[/tex]
cross multiply we have
[tex]234*100= 2600*4.5*T\\\\23400= 11700T\\\\[/tex]
divide both sides by 11700
[tex]23400/11700= T\\\\T= 2 years[/tex]
