Answer:

$52.50

Step-by-step explanation:

Set up the ratio:

[tex]\frac{24.50}{7}[/tex]

Simplify in order to find the cost per gallon.

The cost per gallon is $3.50 because 7 divided by 7 is one and 24.50 divided by seven is 3.5.

Now you have this left:

[tex]\frac{3.50}{1}[/tex]

Multiply the denominator by 15 since Robert needs 15 gallons.

Then, multiply the top by 15 because whatever you do to the denominator, you have to do to the top.

Now you have this left:

[tex]\frac{3.5}{1}[/tex] = [tex]\frac{52.50}{15}[/tex]

Therefore, Robert needs to pay $52.50 in order to recieve 15 gallons of gasoline.

Answer:

  d.  28°, 76°, 76°

Step-by-step explanation:

The sum of the "non-adjacent" interior angles of the triangle is equal to the exterior angle, so is 152°. If those angles are congruent, each is half of 152°, or 76°. The remaining angle is the supplement to 152°, so is 180-152 = 28 degrees.

The interior angles are 28°, 76°, 76°.

Number by x

Answer:

Below!

Step-by-step explanation:

The equation y = 2x + 3/7 is in slope-intercept form: y = mx + b, where m = slope and b = y-intercept.

Note that m is the coefficient of x, and b is the constant.

The coefficient of x is 2, and the constant is 3/7.

Hence, these are the answers.

Given:

Jim stands on a dock that is [tex]3\dfrac{3}{4}[/tex] feet above the lake. He dives down [tex]12\dfrac{1}{2}[/tex] feet below the dock.

To find:

The Jims vertical location relative to the lake surface.

Solution:

We have,

Vertical location of dock relative to the lake surface [tex]=3\dfrac{3}{4}[/tex] feet

He dives down [tex]12\dfrac{1}{2}[/tex] feet below the dock. So,

Vertical location relative to the lake surface [tex]=3\dfrac{3}{4}-12\dfrac{1}{2}[/tex]

[tex]=\dfrac{3\times 4+3}{4}-\dfrac{12\times 2+1}{2}[/tex]

[tex]=\dfrac{12+3}{4}-\dfrac{24+1}{2}[/tex]

[tex]=\dfrac{15}{4}-\dfrac{25}{2}[/tex]

Taking LCM, we get

[tex]=\dfrac{15-50}{4}[/tex]

[tex]=\dfrac{-35}{4}[/tex]

[tex]=-8\dfrac{3}{4}[/tex]

Here, negative sign means Jim location is below the lake surface.

Therefore, Jim is [tex]8\dfrac{3}{4}[/tex] feet below the lake surface.

Answer:

y = -x + 3

Step-by-step explanation:

Use this formula to get the slope [tex]\frac{y2 - y1}{x2 - x1}[/tex]

PLUG IN

[tex]\frac{3 - 7}{0 - -4} \\\\\frac{-4}{4} \\[/tex]

-4/4 = -1

The slope is -1

To find the y- intercept plug your slope and one of your points in this y=mx+b

We will use (0,3)

3 = -1(0) + b (b represents y-intercept)

3 = b

The equation would look like this

y = -x + 3

Hope this helps ya!!

Answer:

Slope = -5/4

Y-Intercept = (0, -4)

Step-by-step explanation:

Step One: Determine two points.

In order to find slope, we have to find the amount of horizontal units (left and right) and vertical units (up and down) that two points are apart. We can choose any two points along this line to compare, so I'll use (0, -4) and (5, 0) since they align perfectly on the grid.

Step Two: Find the difference between the two points.

To find the differences, all we have to do is subtract the second point's X value from the first point's X value. So in this case, we would subtract 5 from 0, which gives us -5.

Next, we have to find the difference in our Y values, so we'll do the same thing here. We'll have 0 - (-4) (or 0 + 4, since subtracting a negative number is technically just addition), which ends up being 4.

Step Three: Put the differences into slope form.

Our slope form is Y/X, or you can think of it as "Rise/Run". We remember that our Y difference was -5, and our X difference was 4, so our end slope would be -5/4.

Step Four: Find the Y-Intercept

Since you have access to a graph of the line, the easiest way is to look at your graph and find the point where the line crosses the Y-axis (the black, vertical line where X = 0). From the graph, we can tell that the blue line crosses the Y-axis at (0, -4), so our Y-Intercept would be (0, -4)

The interest earned on $470 at 4% for 36 months is $56.4

Step-by-step explanation:

We are given

Principal Amount P₀= $470

Rate r = 4% = 0.04

Time t = 36 months = 3 years

We need to find interest I

The formula used is: [tex]I=P_ort[/tex]

Putting values and finding Interest I

[tex]I=P_ort\\I=470(0.04)(3)\\I=56.4[/tex]

3.6

Step-by-step explanation:

260% of 6

100%= 0.06

100% times 2 is 0.06 X 2= 0.12

200%= 0.12

10%= 0.6

60%= 3.6

200% + 60%=

0.12 + 3.6= 3.72

The closest to 3.72 is 3.6

So the answer is 3.6

Answer:

To find this, multiply 6 by the decimal value of the percent.

The answer to this question is 7.404

Answer:

A) Given that the figure is a rectangle, it has a rotational symmetry and by rotating the figure 180° about the center of the figure, the preimage and image will coincide

The figure also has a line symmetry for the vertical line x = 5, and a line symmetry for the horizontal line y = 5

Therefore the figure has both symmetry

B) The transformation that maps the figure unto itself are therefore;

1) Rotating the figure 180° about the point (5, 5) which is the center of the figure

2) Reflection of the figure across the line x = 5 and also reflection of the figure across the line y = 5

Answer:

The answer is C. 16.65 Hope that helps :)

45 percent of 37 is equal to 16.65. The correct answer is C) 16.65.

To find 45 percent of 37, we can multiply 37 by 0.45 since 45 percent is equivalent to 0.45 as a decimal.

37 * 0.45 = 16.65

Therefore, 45 percent of 37 is equal to 16.65.

The correct answer is C) 16.65.

The calculation represents taking 45 percent (or 0.45) of the value 37, resulting in the product 16.65. This means that if you were to take 45 percent of 37, you would obtain the value 16.65. It's essential to understand how to convert percentages to decimals to perform accurate calculations involving percentages.

Answer:

m∠ABD = 114°

Step-by-step explanation:

Given measurements of interior angles are:

m∠D = 2n°

m∠C = 60°

m∠ABD = (4n+6)°

The measurement of exterior angle of a triangle is equal to the sum of two opposite interior angles.

This can be mathematically expressed as:

m∠ABD = m∠C+m∠D

Putting the respective values

[tex]4n+6 = 2n+60\\4n-2n+6 = 60\\2n+6 = 60\\2n = 60-6\\2n = 54\\\frac{2n}{2} = \frac{54}{2}\\n = 27[/tex]

Putting n=27 in (4n+6)°

[tex]=4(27) + 6\\= 108+6 = 114[/tex]

Hence,

m∠ABD = 114°
