u Estimate the amount of the tip by rounding the bill to the nearest ten dollars before calculating. 20% tip on a bill of $123.42 The amount of the tip is approximately $
Answer:
Tip formula
In general, the tip amount is the cost times 0. xx and your total including tip, is the cost times 1. xx where xx = the percent you want to leave. If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip.
Write the equation of the parabola in vertex form.
vertex (1,3), point (2, - 1)
Answer:
[tex]y=-4x^2+8x-1[/tex]
Step-by-step explanation:
I am assuming the parabola has his axis parallel to the y axis. You should remember from theory that the axis (and thus the first coordinate of the vertex) is [tex]-\frac b{2a}[/tex] and then you have two points of passage.
[tex]-b/2a = 1\\a(1)^2 +b(1)+c =3\\a(2)^2+b(2)+c=-1\\[/tex]
Let's solve subtracting the 3rd from the second and keeping the first as is (ok, slightly rewriting it).
[tex]2a=-b\rightarrow 2a+b =0 \\a+b+c=3\\4a+2b+c=-1\\III-II: 4a+2b+c-a-b-c=-1-3 \rightarrow 3a+b=-4 \rightarrow a +(2a+b)=-4\\a= -4; b=8; c =3 +4 -8 =-1[/tex]

Step-by-step explanation:
Solve the equation 3 x 2 - 5x + 1 = 0 expressing your answer correct to two decimal places
Answer: x = 1.4
Step-by-step explanation:
Simplify:
6-5x+1 = 0
Subtract 1 from both sides:
6 -5x = -1
Subtract 6 from both sides:
-5x = -7
Divide both sides by -5:
x = 1.4

find the value of 'h' pls say the answer
Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here A = 16, b = AB = 8 and h = MN , then
[tex]\frac{1}{2}[/tex] × 8 × MN = 16
4 × MN = 16 ( divide both sides by 4 )
MN = 4 cm → A
Explain the process to determine how many solutions the equation

The graph y=e^x is transformed as shown in the graph blow which equation represents the transformed function ?
Answer:
[tex]y=e^x+3[/tex]
Step-by-step explanation:
y=e^x will go through (0,1). Since it goes through (0,4), then the function moves up 3 units. So we need to add 3 after e^x

Regan swims for the Sharks swim team. Last season, the Sharks won 5 swim meets for every 3 they lost. If the Sharks had 16 swim meets in all, how many did they win?
Answer:
10
Step-by-step explanation:
They won 5 for every 3 they lost.
Multiply both numbers by 2 to still have the same ratio.
They won 10 for every 6 they lost.
10 + 6 = 16
They won 10.

(7k^6 + 6k – 10) - ( - 3k^6 - 7k+1)
Answer:
10k^6 + 13k - 11
Step-by-step explanation:
Write (7k^6 + 6k – 10) - ( - 3k^6 - 7k+1) in column format:
(7k^6 + 6k – 10)
- ( - 3k^6 - 7k+1)

What is the product of 7.0\times 10^37.0×10
3
and 8.7 \times 10^58.7×10
5
expressed in scientific notation?
Answer:
1.[tex]4.9\times10^7[/tex]
2.[tex]7.589\times10^{11}[/tex]
Step-by-step explanation:
In order to find the answer to this question convert all notations into standard form and then multiply.
1.
[tex]7.0 \times10^3\times7.0\times10^3[/tex]
[tex]7.0.0.0.=7000[/tex]
[tex]7000\times7000=49000000[/tex]
Convert back into notation:
[tex]49000000 = 4.9\times10^7[/tex]
2.
[tex]8.7\times10^5\times8.7\times10^5[/tex]
[tex]8.7 = 8.7.0.0.0.0. = 870000[/tex]
[tex]870000 \times 870000 = 756900000000[/tex]
Convert back into notation:
[tex]756900000000=7.589\times10^{11}[/tex]
[tex]7.589\times10^{11}[/tex]

You purchase a birthday gift for $105.00. You recall the tag above the gifts to read $175.00 as a retail price. You are pleasantly surprised at the discount that you had not seen. What was the percentage of discount offered on your gift? i assume the answer will be 70%?
We then swap this around for the lower number that equals to 100.
100-60= 40
40%
I hope this is helpful.
Answer:
If the retail price was $175.00, and you purchased this item for $105.00, then the discount was 40%
Step-by-step explanation:
[tex]\frac{105}{175} = \frac{21}{35}= \frac{3}{5} = 0,6[/tex] - that means you paid 60% out of the total price
the discount however is not the percentage that you paid, but the X% OFF, so in that case:
[tex]100 - 60 = 40[/tex]
The discount on this item was 40%
