Answer:
14 inch
Step-by-step explanation:
A = πr^2
153.94 = π * r^2
153.94/π = 49.001 = r^2
√49.001 = r = 7
radius * 2 = diameter
7 * 2 = 14 inch diameter
At the end of Evan's party, there were 1 1 pizzas left. Evan ate į pizza for lunch the next day. What fraction of a pizza was left after Evan's lunch? Move numbers to the boxes to complete the equation. PLEASE HELP WILL GIVE BRAINLIEST
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.

You and your friends have just measured the heights of your dogs. The heights are 600mm, 470mm, 170mm, 430mm and 300mm. Find out the Mean, the Variance, and the Standard Deviation.
Answer:
To find the mean, you have to add all numbers together and divide them by the number of data points.
let me show what I mean:
The heights of the dogs are 600,470,170, 430,300.
Step-by-step explanation:
600+470+170+430+300.
1970.
Now we have to divide 1,970 by 5 ( because we are given 5 data points)
The mean is:
1970/5=394
Variance: First, arrange the data from least to greatest.
s2 = 27130
Standard Deviation: 164.71187

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

What would be the equation to represent this function?
9514 1404 393
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))
At time t = 0 hours, a tank contains 2000 litres of water.
Water leaks from the tank.
At the end of every hour there is x% less water in the tank,
than at the start of the hour.
The volume of water, in litres, in the tank at time t hours is V.
Given that
V = k'V
V. = 1714.75
work out the value of k and the value of x.
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

Two trains leave New York at the same time. One travels south 50 miles per hour and the other traveled east at 40 miles per hour. How far apart are they at the end of THREE HOURS?
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
Answer:
30 miles apart
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

Find the sum of the angle measures in a regular polygon.
A) 720*
B) 900*
C) 1080*
D) 1260*
Please help!! Thanks
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°

What are the lateral area and the surface area of the cone shown below? Round the answers to
the nearest tenth. The figure is not drawn to scale.
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
