Answer:

Sebastian spent $40.40 at the gas station.

Step-by-step explanation:

First let's find how much the gas cost.

So it's $2.91 a gallon, and Sebastian fills 10 gallons of gas, so we multiply.

10 * 2.91 = $29.10

Then we add on the $11.40 from the granola bars and the box of tissues.

$29.10 + $11.40 = $40.50

So the final price should be $40.40. Sebastian spent $40.40 at the gas station.

Answer:

b = - 1.09

Step-by-step explanation:

- 2.9 + b ÷ 0.1 = - 39.9

- 2.9 + b ÷ 0.1 × 0.1 = - 39.9 × 0.1

- 2.9 + b = - 3.99

- 2.9 + 2.9 + b = - 3.99 + 2.9

b = - 1.09

Answer:

Exact form

b=-37/10

Decimal form

b=-3.7

Mixed Number form

b+-3 7/10

Step-by-step explanation:

-2.9+b/1/10+-39.9

-2.9+10b+-39.9

10b=-39.9+2.9

10b=-37

b=-37/10

Answer:

During the early days of mathematical expressions the Greeks needed a shorthand form of representing the summation of several terms hence the choice of ∑ as a sigma Notation.

Step-by-step explanation:

The summation symbol ∑ is the upper case equivalent of capital S in Greek and S represents sum in English.

Answer:

financial equations use the formula

[tex]A=P (1 + \frac{r}n)} ^{nt}[/tex]

where

A is accrued amount

P = principal

r= interest rate

t = number of periods (NOTE: NOT NUMBER OF YEARS !!!)

r = interest rate (NOTE: APR the whole years interest NOT the period)

So in your question the compounding is being done "Semi-annually:

NOTE:

Annual = 1

semi-annual = 2

Quarterly = 4

monthly = 12

So your number of periods is ..... number of years (9) times the number of periods in a year (2 - for semi-annual)

9 * 2 = 18 there are 18 periods

[tex]A=P (1 + \frac{.034}2)} ^{18}[/tex]

Number of books she has not read =8

Step-by-step explanation:

Number of books Tara has=160

Number of books she has read =Percentage of what she has read x Number of book s she has =95% x 160=152

Number of books she has not read =Number of books Tara has- Number of books she has read=160-152=8

(√7)3=732

Explanation:

To write

(√7)3

in exponential form, one needs two identities - n√a=a1n

and (am)n=a(m×n)

which is true for all rational

m and n.

Hence,

(√7)3= (712)3

= 7(12×3)

= 732

Answer:

20.8

Step-by-step explanation:

Use the Pythagoras's Theorem

12²-36²=[tex]\frac{x}{2}[/tex]²

144-36=[tex]\frac{x}{2}[/tex]²

108=[tex]\frac{x}{2}[/tex]²

Root both sides

√108=√[tex]\frac{x}{2}[/tex]²

[tex]\frac{x}{2}[/tex]≈10.4

[tex]\frac{x}{2}[/tex]·2=10.4·2

x=20.8

It is 34.90

Answer:

[tex] \displaystyle x = 15[/tex]

Step-by-step explanation:

by triangle midsegment theorem we obtain:

[tex] \displaystyle \frac{10x + 44}{2} = 8x - 23[/tex]

simplify division:

[tex] \displaystyle 5x + 22 = 8x - 23[/tex]

move 5x to right hand side and -23 to the left hand side and change its sign:

[tex] \displaystyle 22 + 23= 8x - 5x[/tex]

simplify addition:

[tex] \displaystyle 8x - 5x = 45[/tex]

collect like terms:

[tex] \displaystyle 3x = 45[/tex]

divide both sides by 3:

[tex] \displaystyle x = 15[/tex]

and we are done!

Answer:

cheeseburgers cost= $1.25 and

Fries cost = $0.75

Step-by-step explanation:

Given data

let cheeseburgers be x

and fries be y

4x+3y= 7.25--------------1

6x+3y= 9.75--------------2

Subtract the equations

   4x+3y= 7.25--------------1

  6x+3y= 9.75--------------2

-2x+0= -2.5

2x=2.5

x=2.5/1.5

x= 1.25

Put x=  1.25 in 1

 4x+3y= 7.25--------------1

 4(1.25)+3y= 7.25--------------1

 5+3y= 7.25

3y=7.25-5

3y=2.25

y= 2.25/3

y= 0.75

Hence cheeseburgers cost= $1.25 and

Fries cost = $0.75

Answer:

y+3x+1

Answer: (100th answer)

perimeter of field b = 260 m

Step-by-step explanation:

First we have to find what is 7/12 of 108?

Well first we need to know what 1/12 of 108 is. Which means we do 108/12. That equals 9. so if 1/12 of 108 = 9

then 7/12 of 108 is 9*7 which is 63.

The width of field A is 63 plus its length, width again and its length again would be its perimeter or

2l + 2w is its perimeter, where l is length and w is width

108*2+63*2= perimeter

216+126 = ?

342 is the perimeter of field A.

We aren't done though.

We have to find 5/6 of 342.

1/6 of 342 is 342/6

342/6 = 52

1/6 of 342 = 52 meaning 5/6 of 342 is equal to 5*52.

5*52 = 260

the perimeter of field b is 260

Answer:

You save $55

Step-by-step explanation:

To find out what the 75% of the 220 is, you need to do .75 times 220 and then after you get the answer, subtract that number from 220 and you have your answer.
