My car has a tank of 50 litres. If it is 50% full, how many litres do I have?

Step-by-step explanation:

2t = 5t +2

2t - 5t = 2

-3t = 2

t = -2/3

Answer:

9+8b^(2)

Step-by-step explanation:

common factors are -1, 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]

My answer was incorrect and I don't know how to delete an answer

Answer:

75*10=750

Step-by-step explanation:

10 tickets, each 75 dollars, so u multiply 75 by 10 to get 750, just write 75 and rop the 0. $750

Answer:

$750

Step-by-step explanation:

To find the cost of 10 tickets multiply cost of 1 by 10

1 0 cost = $75 × 10 = $750

Answer:

SAS

Step-by-step explanation:

You are already given that two sides are congruent, thus making the "s" part. You can further say that two angles are congruent, due to the verticle angle theorem!

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

Answer:

448.

Step-by-step explanation:

314 - (-134)

= 314 + 134

= 448.

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

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.

Step-by-step explanation:

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]

Hope this helps.

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)

Distribute the - sign throughout the second expression:

​

  (7k^6 + 6k – 10)

(  3k^6 + 7k - 1)

--------------------------     Combine like terms

 10k^6 + 13k - 11       This is the correct end result after the indicated

                                   subtraction

Answer:

9 4

- + -

3 2

Step-by-step explanation:

Replace the first x with 9 and the second with 4

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%

I do that in school its annoying.

6,2.75?

Answer:

the answer is inspection

Step-by-step explanation:

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

Answer:

l=4π
