Step-by-step explanation:

17*$2.499 = $42.48300

Rounded to the nearest cent = $42.48

Therefore, it would cost $42.48 to buy 17 gallons of gas.

Answer:

The original number is 83

Step-by-step explanation:

let the number be ab

Sum of the two is 11

a + b = 11

tens digit a is one less than 3 times the ones digit

3b - a = 1

a = 3b - 1

3b -1 + b = 11

4b = 11 + 1

4b = 12

b = 12/4

b = 3

a = 3b - 1

a = 3(3) - 1

a = 9-1

a = 8

Step-by-step explanation:

The graph for the line is attached below.

The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.

In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.

Usually, data that varies over time is represented with a line graph.

Given:

y = 3 - 1/2x

Now, let us find the point to plot on the graph.

So, take x= 0

y= 3

and, take x= 2

y= 3- 1

y= 2

and, take x = 6

y = 3 - 3

y= 0

Thus, the points are (0, 3), (2 , 2) and (6,0).

Answer:

B

Step-by-step explanation:

Since Greg has calculated that his least or minimum speed should.be 50 miles per hour ;

Then the line starts at 50 with the starting point shaded due to the atleast notation.

Then atleast means that, Gregg may need to travel at a higher speed than 50, so the direction of the arrow moves to the right of the number line depicting a possible increase in Gregg's speed.

Therefore, the number line which best conveys Gregg's situation is B.

Answer:

The amount Mary would have in her account in 5 years is approximately £13,131.7

Step-by-step explanation:

The amount Mary deposits in the account, P = £10,000

The amount in interest paid by the account, r = 5.6%

The mode by which the interest is calculated = Compound interest

The number of years for which the amount (£10,000) will be kept in the account, t = 5 years

The number of times that the given interest applies per year, n = 1

The amount, "A",  Mary would have in her account in 5 years, is given by the compound interest formula as follows;

[tex]A = P \cdot \left ( 1 + \dfrac{r}{n} \right ) ^{n \cdot t}[/tex]

Where;

A = The amount accrued in the account after the given elapsed periods

P = The principal or initial balance in the account = £10,000

r = The compound interest rate = 5.6/100

n = The number of times the interest is applied in one period of time = 1

t = The sum of the duration for the interest applies = 5

Substituting the given values, we have;

[tex]A = 10,000 \times \left ( 1 + \dfrac{0.056}{1} \right ) ^{1 \times 5} = 13,131.65883211776[/tex]

Therefore, the amount Mary would have in her account in 5 years = A ≈ £13,131.7

If Luca wants to leave a 16% tip on the total amount including the tax, he should pay $32.24.

Step-by-step explanation:

First, you have to calculate the 4% of the bill and add that amount to the total of the bill to determine the total amount including the tax:

193.75¨*4%=7.75

193.75+7.75=201.5

Now, you have to calculate 16% of the amount including the tax:

201.5*16%=32.24

According to this, the answer is that if Luca wants to leave a 16% tip on the total amount including the tax, he should pay $32.24.

The third angle must be 104

Step-by-step explanation:

The last angle is found by adding 51 and 25 and the subtracting it from 180

Answer:

104°

Step-by-step explanation:

According to angle sum property of a triangle , sum of all the angles of triangle is equal to 180°.

So, let the third angle be 'x'. According to angle sum property of triangle ,

[tex]x + 25 + 51 = 180[/tex]

[tex] = > x + 76 = 180[/tex]

[tex] = > x = 180 - 76 = 104[/tex]

Answer:

8. Flour = 150 grams

9. Original sum of money = 110 pounds

Step-by-step explanation:

8. Let the quantities of butter, flour and sugar be 2x, 3x and 4x grams respectively.

So,

2x + 3x + 4x = 450

9x = 450

x = 450/9

x = 50

Flour = 3x = 3*50 = 150 gram

9.

Let Abby, Neil and Dylan have 2x, 4x and 5x pounds respectively.

Since Neil has 40 pounds.

So, 4x = 40

x = 40/4

x = 10

Total amount = 2x + 4x + 5x = 11x = 11*10 = 110 pounds.

Original sum of money = 110 pounds

Answer:

The value of y is 847 for x=11

Step-by-step explanation:

It is given that y is directly proportional to the square of x

This can be written mathematically as:

[tex]y \propto x^2[/tex]

Removing the proportionality symbol introduces a proportionality constant in the equation which is denoted by k

[tex]y = kx^2[/tex]

Given that "When x is 5, y is 175"

[tex]175 = k (5)^2\\175 = k*25\\k = \frac{175}{25}\\k = 7[/tex]

Putting the value of k

[tex]y = 7x^2[/tex]

Now putting x = 11

[tex]y = 7(11)^2\\y = 7 * 121\\y = 847[/tex]

Hence,

The value of y is 847 for x=11
