Mario buys tickets for either 47 or 57 dollars. He purchases 14 tickets and spends 738 dollars. How many tickets did he purchase at each price?

Answer:

y = -3x - 2

Step-by-step explanation:

to find slope use m= y2-y1/x2-x1

m= -4-2/6-4

m= -6/2

m=-3

then use point slope formula (y-y1) =m(x-x1)

(y-2) = -3(x-4)

simplify

y-2 = -3x - 4

turn into slope intercept form

y = -3x - 2

Answer:

Time = 8 weeks

Step-by-step explanation:

Given the following data;

Savings = $23

Savings made = $65

Cost of bike = $273

To find the amount required to purchase the bike;

Balance = cost of bike - savings made

Balance = 273 - 65

Balance = $208

Next, we find the number of weeks required to save $208 (balance).

Time = balance/savings

Time = 208/23

Time = 8 weeks

Answer:A

Step-by-step explanation:

To round each number to the nearest tenth, we have to look at the second digit after the decimal point, the hundredths. We look at tenths to round whole numbers, hundredths to round tenths, thousandths to round hundredths, etc. If the digit is 4 or below, then we would round down. If the digit is 5 or up, we would round up.

11.14

The digit is below 5, so we round down to 11.1.

9.543

The digit is also below 5, so we round down to 9.5.

Henceforth, adding these two numbers, we can conclude that an accurate estimation of the sum is 11.1 + 9.5, or 20.6.

If we wanted to round this answer further, we would use the same rounding rule. 20.6, where the tenths place digit, 6, is above 5, would be rounded up to 21.

Answer:

See below

Step-by-step explanation:

A 30° angle is measured 30° counterclockwise while a -30° angle is measured 30° clockwise. Therefore, you can say -30°=360-30°=330° because 30° is a reference angle located in Quadrant IV.

Answer:

8

Step-by-step explanation:

Usually we would have to use a formula to find the distance between the two points, however the x values of both coordinates are the same therefore we can find the distance between the two points by subtracting the smaller y value (-3 ) from the larger y value ( 5 )

Distance = 5 - ( - 3 )

* the two negative signs cancels out *

5 + 3 = 8

The distance between the two points is 8 units

Answer:

72°

Step-by-step explanation:

The interior angles of a triangle sum to 180°. Since there are two angles at 54°, we can use the equation x = 180 - 54 - 54 or x = 180 - 2(54), which will give us 72°.

Answer:

axis of symmerty = x coordinate of vertex = -b/2a

-6/2 = -3 = x

vertex = (-3,y)

-3^2 +6(-3)

9-18 = -9 = y

(-3,-9) = vertex

Answer:

"5.5129 g/cm³" is the appropriate solution.

Step-by-step explanation:

According to the question, the values are:

Iron's density,

= 7.874 g/cm³

Base edge length,

= 4 cm

Base edge width,

= 9 cm

Height,

= 5 cm

Mass,

= 425 g

As we know,

The Density of rectangular pyramid will be:

= [tex]\frac{Mass}{Volume}[/tex]

or,

= [tex]\frac{Mass}{Length\times Width\times height}[/tex]

On putting all the given values, we get

= [tex]\frac{425}{4\times 9\times 5}[/tex]

= [tex]\frac{425}{180}[/tex]

= [tex]2.3611 \ g/cm^3[/tex]

hence,

The difference will be:

= [tex]7.874-2.3611[/tex]

= [tex]5.5129 \ g/cm^3[/tex]

Answer:

radius = 4 units and center of circle = (0,10)

Step-by-step explanation:

The radius of this circle from the given equation of circle is equal to 4

Data;

The equation of a circle is given as

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

Let's substitute our given variables here and solve

[tex](x-h)^2 + (y - k)^2 = r^2\\(x-0)^2 + (y-10)^2 = 4^2[/tex]

All we need to do here try to write the equation in the standard form which is given above and then pick the value of radius (r) from there

The radius of this circle is equal to 4

Answer:

cosine

Step-by-step explanation:

Given:

The box model represents 250.

To find:

The value of the green color.

Solution:

In the given figure,

Total number small boxes = 100

Number of green boxes = 42

The fraction of green color in the given figure is [tex]\dfrac{42}{100}[/tex].

The box model represents 250. So, the value of the green color is:

[tex]\dfrac{42}{100}\times 250=105[/tex]

The value of green color is 105. Therefore, the correct option is D.

Given:

The graph of a piecewise function.

To find:

The points of discontinuity.

Solution:

The function is discontinuous at a point if:

1. There is a jump in the graph of function.

2. There is a hole in the graph at that point.

3. The function approaches to infinite at that point.

From the given graph it is clear that the graph of the function has jumps are at points [tex]x=-2[/tex] and [tex]x=0[/tex].

So, the function is discontinuous at [tex]-2,0[/tex].

Therefore, the correct option is (c).

Answer:

what diagram

Step-by-step explanation:

Answer: 132.7

Step-by-step explanation: divide 13 by 2 then multiply 6.5 by itself. Then multiply 42.25 by 3.14 or pi and you get 132.7

In the diagram, we can see that the angles are linear pair, which means they are of 180°. Now,

Supplementary angles are those which form an angle of 180° where as Complementary angles are those which form an angle of 90°. Certainly, the as it is a linear pair, they both are supplementary angles.

Now, we can say that:

= x + 118 = 180 ------------ [ Supplementary angles]

= x = 180 - 118

= x = 62

That's how the option B is correct.
