Answer:
540 cups
Step-by-step explanation:
Number of cone shaped cups = Volume of cylinder/volume of cone
Cylinder:
r = 10 inches
h = 36 inches
Volume = πr²h
= π * 10*10*36
= 3600 π cubic inches
Cone:
r = 2 inches
h = 5 inches
Volume = (1/3)πr²h
[tex]=\frac{\pi*2*2*5 }{3}\\\\=\frac{20\pi }{3} cubic inches[/tex]
Number of cones = 3600 π / (20π/3)
[tex]= 3600\pi *\frac{3}{20\pi }\\\\= 180*3[/tex]
= 540

Answer:
On the circle
Step-by-step explanation:
The distance between D and G is:
[tex]\sqrt{(-1-(-10))^2+(3-1)^2}=\sqrt{9^2+2^2}=\sqrt{81+5}=\sqrt{86}[/tex]
If point J is not exactly this far, then it is not on the circle.
[tex]\sqrt{(-1-(-3))^2+(12-3)^2}=\sqrt{2^2+9^2}=\sqrt{5+81}=\sqrt{86}[/tex]
Therefore, it is on the circle. Hope this helps!
Solve using elimination.
- 8x + 2y = -20
8x - 5y = 14
Answer:
x = 3, y = 2
Step-by-step explanation:
~ Through process of elimination ~
1. - 8x + 2y = -20
+ 8x - 5y = 14
2. Simplify to solve for y through simple algebra:
2y - 5y = -20 + 14 ⇒ - 3y = - 6 ⇒ y = 2
3. Now substitute this value of y into the to equation - 8x + 2y = -20 to get x:
- 8x + 2 ( 2 ) = -20 ⇒
-8x + 4 = -20 ⇒
-8x = -24 ⇒
x = 3

The mean life of a Brand Q car battery is 36 months. The standard deviation is 4 months.
68% of all batteries will have a life between _____ months and _____ months.
95% of all batteries will have a life between _____ months and _____ months.
Answer:
Step-by-step explanation:
Let x be a random variable representing the life of a Brand Q car battery. With the mean and standard deviation given, then the Empirical Rule says the that
1) About 68% of the x values lie between 1 standard deviation below and above the mean.
2) About 95% of the x values lie between 2 standard deviations below and above the mean.
3) About 99.7% of the x values lie between 3 standard deviations below and above the mean.
From the information given,
mean = 36 months
Standard deviation = 4 months
Therefore,
1) 68% of all batteries will have a life between 36 - 4 = 32 months and 36 + 4 = 40 months.
2) 95% of all batteries will have a life between 36 - 2(4) = 28 months and 36 + 2(4) = 44 months.
The number of goldfish in a tank is 19, and the volume of the tank is 52 cubic feet. What is the density of the tank?
Answer:
0.37 goldfish per cubic feet
Step-by-step explanation:
Density has the formula = number/volume
Density = 19/52 = 0.36538 which is rounded to 0.37
Answer:
0.37 goldfish / cu ft. (to the nearest hundredth).
Step-by-step explanation:
Density = number of goldfish / volume of the tank.
That is 19 / 52
= 0.37 goldfish / cu ft.

At a party, everyone shook hands with everybody else. There were 66 handshakes. How many people were at the party?
Answer:
66?lol
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
In general, with n+1 people, the number of handshakes is the sum of the first n consecutive numbers: 1+2+3+ ... + n.
Since this sum is n(n+1)/2, we need to solve the equation n(n+1)/2 = 66.
This is the quadratic equation n2+ n -132 = 0. Solving for n, we obtain 11 as the answer and deduce that there were 12 people at the party.
Since 66 is a relatively small number, you can also solve this problem with a hand calculator. Add 1 + 2 = + 3 = +... etc. until the total is 66. The last number that you entered (11) is n.
hope this helped i had this same question and i answered it

How to solve this question
Answer:
3 hours
Step-by-step explanation:
let h be the hours of tuition, then
11h + 8.5 ← models the cost of Leda's tuition
10.5h + 10 ← models the cost of Thanh's tuition
Equate the 2 and solve for h
11h + 8.5 = 10.5h + 10 ( subtract 10.5h from both sides )
0.5h + 8.5 = 10 ( subtract 8.5 from both sides )
0.5h = 1.5 ( divide both sides by 0.5 )
h = 3
Thus after 3 hours the price would be the same for both instructors
Kendra made a scaled copy of the following square. She used a scale factor less than 111. What could be the side length of the scaled copy of the square.
Answer:
B,C,E
Step-by-step explanation:
khan academy
Side length of the scaled copy of square is smaller than original.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
Given,
Scale factor of scaled copy of square is less than 1.
Scale factor basically defines the ratio between the sides of the constructed square to that of the original square.
if scale factor is less than 1 then the sides of the constructed square is smaller than that of the original square.
Hence, side length of constructed square is smaller than the original square.

Question:
Which expressions are equivalent to ½ + 3c + ⅘.
Check all that apply.
Answer:
½ + 3c + ⅘ is equivalent to
1. ⅒(30c + 13)
2. 3c + 13/10
Step-by-step explanation:
The options are not well presented.
However, I'll give simplify the given expression in the question above.
Given: ½ + 3c + ⅘.
Required: Simplify
We start by collecting like terms
3c + ½ + ⅘
From this point, the expression can be solved in two ways
1. Solve fractions
This gives [Find LCM]
3c + (5 + 8)/10
3c + 13/10
3c + ⅒(13)
This can still be solved further [Find LCM]
(30c + 13)/10
⅒(30c + 13)
Hence ⅒(30c + 13) is equivalent to ½ + 3c + ⅘.
2. Convert fractions to decimal
½ + 3c + ⅘ becomes
0.5 + 3c + 0.8
Collect like terms
3c + 0.5 + 0.8
3c + 1.3
Convert decimal to fraction
3c + 13/10
3c + ⅒(13)
This can still be solved further [Find LCM]
(30c + 13)/10
⅒(30c + 13)
Hence ⅒(30c + 13) is equivalent to ½ + 3c + ⅘.
This is as far as the expression can be evaluated

Step-by-step explanation:
During the first few years of a tree's life, its growth rate is linear. For example, an oak tree grows at a rate of 1.5 feet per year for the first twelve years. Mostafa plants a maple tree in his backyard and measures its height at 4 feet. Two years later, Mostafa measures the tree again and finds that its height is now 6.5 feet. Which statement is correct given this information?
Answer:
Mostafa's maple tree grows at a slower yearly rate than an oak tree.
Step-by-step explanation:
Given that:
An oak tree grows at a rate of 1.5 feet per year for twelve years;
After 12 year; the oak tree will be = 12 × 1.5 = 18 feet per year.
Now; we are being told that Mostafa plants a maple tree at his backyard and measures its height at 4 feet.
i.e x years = 4 ft
two years later ; it height is now 6.5 ft
thus;
x year = 4 ft
x + 2 = 6.5 ft
[tex]6.5 * x = (x+2)4\\ \\ 6.5 x = 4x + 8\\ \\ 6.5x-4x = 8\\ \\ 2.5x = 8\\ \\ x = \dfrac{8}{2.5}\\ \\ x = 3.2[/tex]
Thus ; Mostafa first measured the height of the tree when it is 4 ft at the age year of 3.2
So;
if 3.2 year = 4 ft
1 year = x
x = [tex]\dfrac{4 *1 }{3.2}[/tex]
x = 1.25 ft
So if an oak tree grows at the rate of 1.5 ft in a year.
Then, Mostafa's maple tree grows at the rate of 1.25 ft in a year.
From the given information in the diagram attached below; we can infer that :
Mostafa's maple tree grows at a slower yearly rate than an oak tree.

1/4 of the cake.
Step-by-step explanation:
Since he ate 1/3 of 3/4 of the chocolate cake, we will need to multiply fractions to solve this.
[tex]\frac{3}{4} * \frac{1}{3} = \frac{3}{12} = \frac{1}{4}[/tex]

Step-by-step explanation:
the equation for slope intercept is y=mx+b, where m is the slope and b is the y intercept. The y intercept is -2, (where the line comes in contact with the x axis) and the slope is determined from the equation y2-y1/x2-x1 (rise over run) With this, we can see the slope is 1. hope this helps
