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 equation of line parallel to y = 2x + 7 and passes through (-1, 3) is: [tex]y = 2x+5[/tex]

Step-by-step explanation:

Given equation of line is:

y = 2x + 7

The general form of equation in slope-intercept form is:

[tex]y=mx+b[/tex]

Here m is the slope and b is the y-intercept

Comparing the equations, we get

m = 2

Let m_1 be the slope of line parallel to given line

[tex]m_1 = m\\m_1 = 2[/tex]

The equation of line parallel to given line will be:

[tex]y=m_1x+b[/tex]

Putting the value of slope

[tex]y = 2x+b[/tex]

To find the y-intercept, putting (-1,3) in the equation

[tex]3 = 2(-1)+b\\3 = -2+b\\3+2 = b\\b = 5[/tex]

The equation is:

[tex]y = 2x+5[/tex]

Hence,

The equation of line parallel to y = 2x + 7 and passes through (-1, 3) is: [tex]y = 2x+5[/tex]

the advantages of being paid salary is u get it even if u work 1 hour and the disadvantage of getting paid hourly is u have to work for along time

He owes 200 so the first part of the equation would be the starting value of -200.

You would then multiply 25 by the number of months he has given them money and add that to the -200, this would make the -200 a smaller value every month meaning he owes his parents less money.

The answer is A. y = -200 + 25x

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:

$1400

Step-by-step explanation:

Assuming that you would pay off the debt now and not wait any longer than to calculate how much more money you need you simply need to subtract the $1000 that you have from the total which is $2400.

$2400 - $1000 = $1400

Finally, we can see that you need an extra $1400 in order to finish paying off the debt. Unless you wait more time and the overall debt owed rises some more.

Answer:

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:

250 hamburgers were sold on Sunday

Step-by-step explanation:

Let h be the number of hamburgers and c be the number of cheese burgers, then according to given statements, the equations will be:

[tex]h+c = 567\ \ \ \ Eqn\ 1\\c = h+67\ \ \ Eqn\ 2[/tex]

We can use the substitution method to solve the given system of equations.

Putting c= h+67 in equation 1

[tex]h+h+67 = 567\\2h+67 = 567\\2h = 567-67\\2h = 500\\\frac{2h}{2} = \frac{500}{2}\\h = 250[/tex]

Putting h=250 in equation 2

[tex]c = 250+67 = 317[/tex]

Hence,

250 hamburgers were sold on Sunday

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

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

Answer:

Step-by-step explanation:

For every 4 boys there are 5 girls and 9 students at the school. So that means that 49 of the students are boys. 49 of the total number of students is 120 students:

49×?=120

If 49 the number of students is 120, then 14 of 120 is 19 of the total number of students. In other words, 14×120=30 is 19 the total number of students. Then 9 times this amount will give the total number of students:

9×30=270

So there is a total of 270 students at the school. Note that this is equivalent to finding the answer to the division problem:

120÷49=?

We can see all of this very succinctly by using a tape diagram:

Bar_diagram_67722d3e6005449e4fbe5c57eaad4f3c

There are 4 units of boys and 9 units of students. Therefore 4/9 of the students are boys.

4 units = 120

1 unit = 30

9 units = 270

There are 270 students altogether.

Students can multiply the numbers in the first row by 10 to get the second row, and then double that amount to get the third row. Adding the entries in the second and third row gives the fourth row that has the solution.

Alternatively, since 120÷4=30, students can just multiply the numbers in the first row by 30 to get the values in the fourth row.

In every row, we can see that the fraction of the students that are boys is 49.

looking at the last row, we can see that the total number of students will be 4×30+5×30=120+150=270.
