So, after Evan's lunch, there was 7/8 quantity of pizza left.

Here we can write,

The simple fraction of [tex]1\frac{1}{8}[/tex] = 9/8

So, if there were 9/8 pizzas left at the end of the party and Evan ate 2/8 of a pizza for lunch,

we can start by subtracting the amount that Evan ate from the total amount that was left,

⇒ 9/8 - 2/8

To subtract fractions with like denominators,

We can simply subtract the numerators and keep the same denominator,

⇒ 9/8 - 2/8 = 7/8

So, after Evan's lunch, there were 7/8 of a pizza left.

Answer:

D) 1260°

Step-by-step explanation:

In an n-sided polygon, the sum of all angles is equal to (n-2)*180°.

Look at it this way - let's add a point in the middle and connect it to each vertex. Then we've got n triangles for a total of n*180°, but all of the angles at the middle point aren't "part" of the polygon, so a full 360° angle should be subtracted, giving us n*180°-360° = (n-2)*180°

You can easily confirm that it works for triangles and quadrangles ;)

The figure in the picture has 9 sides, so the sum of angles is (9-2)*180° = 7*180° = 1260°

1260°

Answer:

  y = 28(x +5)(x -2)/((x +5)(x +7)(x -8))

Step-by-step explanation:

The vertical asymptotes at x=-7 and x=8 and the hole at x=-5 tell you that the denominator has factors of (x +7)(x +5)(x -8) and the numerator has a factor of (x +5). The zero-crossing at x=2 tells you there is another numerator factor of (x -2). So, for some vertical scale factor 'a', the function so far must be ...

  f(x) = a(x +5)(x -2)/((x +7)(x +5)(x -8))

For this, we have ...

  f(0) = 10a/280 = a/28

We want f(0) = 1, so the value of 'a' must be 28.

The equation that produces the graph is ...

  y = 28(x +5)(x -2)/((x +5)(x +7)(x -8))

The histogram that best represents the data is the first histogram.

An histogram is a graph that shows the number of times each element of x was observed.

here, we have,

For this problem, we have that the data-set is given by:

3.4 1.1 1.7 3.1 5.8 3.2 3.7 3.4 1.6 3.5 3.9 3.8 1.1 1.9 1.8.

We divide the data-set into ranges, hence the number of elements in each range is given as follows:

6 students download between 0 and 2 songs per week.

8 students download between 2 and 4 songs per week.

1 student download between 4 and 6 songs per week.

Hence the first histogram best represents the data.

Answer:

192 miles

Step-by-step explanation:

This is a right triangle problem

One leg of the triangle is

50 * 3 = 150

The other leg is

40 * 3 = 120

the distance is the hypotenuse

c^2 = 150^2 + 120^2

c^2 = 22500 + 14400

c^2 = 36900

Take the square root of both sides

c = 192.093727123

c ≈ 192 miles

Step-by-step explanation:

Im not sure if this is the corect answer to this but this is what i think what i did was get 50 x 3 and 40 x 3 since they starded at the same times and finished after 3 hours so multiply your numbers by 3 so...

50 x 3=150

40 x 3=120

150-120=30 miles apart

Answer:

lateral surface area of the cone = 829.0ft²

Hence the total surface area is 1,208.9ft²

Step-by-step explanation:

lateral surface area of the cone = πrl

l is the slant side = 24ft

r is the radius = 11ft

lateral surface area of the cone = π(11)(24)

lateral surface area of the cone = 3.14 * 264

lateral surface area of the cone = 828.96ft²

lateral surface area of the cone = 829.0ft²

Total surface area = πr(r+l)

r is the radius = 11ft

l is the slant side = 24ft

Total surface area = π(11)(11+24)

Total surface area = π(11)(35)

Total surface area = 3.14 * 385

Total surface area = 1,208.9ft²

Hence the total surface area is 1,208.9ft²

Answer:

k= 0.95

x = 5

Step-by-step explanation:

V₀=2000 because at the start (when t=0), there's 2000l in the tank.

V[tex]_{t}[/tex]=[tex]k^{t}[/tex]V₀

V[tex]_{t}[/tex]=2000[tex]k^{t}[/tex]

V₃=1714.75=2000k³

k³=0.857375

k= 0.95

-----

V[tex]_{t}[/tex]=2000[tex]k^{t}[/tex]

V[tex]_{t}[/tex]=2000[tex](0.95^{t})[/tex]

V₁=2000(0.95)=1900

So from V₀ to V₁, the tank loses 100l, which is 5% of it's volume at the start of the hour (100/2000=5%). Therefore x = 5
