Answer:
54461.33 cubic feet
Step-by-step explanation:
Given data
Height of cylinder= 40 feet
Radius= 20feet
Height of cone= 10 feet
Radius of cone= 20feet
Volume of Cylinder= πr^2h
Volume of Cylinder= 3.142*20^2*40
Volume of Cylinder= 3.142*400*40
Volume of Cylinder= 50272 cubic feet
Volume of Cone= 1/3πr^2h
Volume of Cylinder= 1/3*3.142*20^2*10
Volume of Cylinder= 1/3*3.142*400*10
Volume of Cylinder= 1/3*12568
Volume of Cylinder=4189.33 cubic feet
Hence, the volume of the silo = volume of cylinder+ volume of cone
Volume of silo= 50272+4189.33
Volume of silo=54461.33 cubic feet

If the probability that a student in school wears contacts is 0.38 and the probability that a student in the same school has a car is 0.42, what is the probability that a student wears contacts and has a car?
Answer:
Probability [Student wears contacts and has a car] = 0.1596
Step-by-step explanation:
Given:
Probability [Student in school wears contacts] = 0.38
Probability [Student in the same school has a car] = 0.42
Find:
Probability [Student wears contacts and has a car]
Computation:
P[A and B] = P(A) × P(B)
So,
Probability [Student wears contacts and has a car] = Probability [Student in school wears contacts] x Probability [Student in the same school has a car]
Probability [Student wears contacts and has a car] = 0.38 x 0.42
Probability [Student wears contacts and has a car] = 0.1596
the ratio of colored papers to white papers is 3/8 if there are 48 white papers, how many coloured papers are there
The number of coloured papers as per the given problem is 18.
What is the application ratio and proportion?A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.
Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.
Given that,
The ratio of coloured papers to white papers is 3/8.
And, the number of white papers is 48.
Suppose, the number of coloured papers be x.
Then, as per the question the following equation can be obtained,
3/8 = x/48
=> x = 3/8 × 48
=> x = 18
Hence, the number of coloured papers is 18.

I REALLY NEED HELP PLS HELP ME ON THIS MATH
Answer:
Ok, we can define a function as a relation that maps elements from a set (the domain) into elements from another set (the range), such that each element in the domain can be mapped into only one element of the range.
2) Here you choose the autographed poster, and we know that each one of these costs $10.
So, if the artist sold x posters, then he/she would earn x times $10:
earnings = $10*x
So we can create a function:
f(x)
such that f(x) represents the total earnings of the artist for selling x posters.
And we already know the equation for the earnings, so the function will be:
f(x) = $10*x
3) Now, it asks us if the values:
-2, -1, 0, and 1
be appropiate for the domain of the function.
Remember that x represents the number of posters that the artist sold.
Then, if we take x = -2 or x = -1 (like the first two given values) this would mean that the artist sold a negative number of posters, which has no real sense in the situation given. So we can conclude that these values should not be in the domain of the function.
For the other two cases, 0 and 1, these two can be in the domain, because these represent the case where the artist sold only one poster and the case where the artist did not sell any poster (that are two possible cases)

This prism has a right triangle for a base. What is the volume of the prism?
length = 6 x 1/3 = 2 inches
width = 4 x 1/3 = 4/3 inches
height = 8 x 1/3 = 8/3 inches
volume = lwh = 2 x 4/3 x 8/3 = 64/9 cubic inches
Another approach is the following:
There are 6 x 4 x 8 = 192 cubes inside the prism,.
Each cube has a volume of 1/27 cubic inches.
Therefore total volume = 192 x 1/27 = 192/27 = 64/9

Answer: The Answers are A, and C.
Answer:
The answer is C and D
Step-by-step explanation:
If you find the percentage of 95% of 6 it will give you an answer of 5.7
.95 x.006 equals 0.0057
95x6 equals 570
0.95 x 6 equals 5.7
95/100 x 6 equals 5.7
all of the following are equivalent except...
A. 8x + 3x
B. (8+3)x
C. 11x
D. 11x^2
Answer:
d) [tex]11x^2[/tex] because that would be the same as [tex]11x * 11x[/tex]

Solve for x.
x = [?]
X - 6
8x + 24
Answer:
x=18
Step-by-step explanation:
Both angles are supplementary angles and form 180
Set your formula up as following
(x-6) + (8x+24) = 180
x+8x-6+24=180
9x=180+6-24
9x=162
x=162/9
x=18
Now substitute 18 for x to get your angles and check your work .

Step-by-step explanation:
Hanna: 20 1/4 cups per 9 servings.
We divide 20 1/4 by 9 to find the amount per serving.
20 1/4 / 9 = 81/4 / 9/1 = 81/4 * 1/9 = 9/4
Hanna's recipe uses 9/4 cup per serving.
Pocahontas: 3/4 cup more per serving than Hanna
9/4 + 3/4 = 12/4 = 3
Pocahontas uses 3 cups per serving
3 * 8 = 24
Pocahontas uses 24 cups of flour for 8 servings.

There are a total of 76 teachers and students watching a school play. There are 4 teachers and 40 girls.
Write the ratio of boys to girls in lowest terms.
Given that : There are a total of 76 teachers and students watching a school play. There are 4 teachers and 40 girls.
Need to find : the ratio of boys to girls in lowest terms.
Firstly we need to find out the number of boys . For that subtract the number of teachers and girls from total number of teachers and students. That will be ,
[tex]\implies \sf n( boys) = 76 - 4 - 40 =\red{ 32 }[/tex]
Therefore our required ratio will be:-
[tex]\implies \sf 32 : 40 = \boxed{\sf 4:5 }[/tex]
Hence the required answer is 4:5 .

which does not describe the equation
[tex] \sqrt{x = - 2} [/tex]
Answer:
which of what ?
and the equation is not right. I don't know what you mean.
do you mean x = sqrt(-2) ?
all I can tell you just based on that assumption is that you can transform that into
[tex]x = \sqrt{2} \times i[/tex]
you know,
[tex]i = \sqrt{ - 1} [/tex]
but what else you might need is completely unclear.

When the sun is at a certain angle in the sky, a 50 foot building will cast a 20 foot shadow. What is the length of the shadow in feet cast by a 20 foot pole at the same time?
Answer:
Prepara a bar graph. (Mention the scale)
Potato= 25 per kg
Tomato= 40 per kg
Cauliflower= 10 per kg
Chilli= 15 per kg
Lemon= 30 per kg
Answer:
8 ft
Step-by-step explanation:
The height of the building/pole and shadow of each are in proportion.
let x be the length of shadow of the pole, then
[tex]\frac{50}{20}[/tex] = [tex]\frac{20}{x}[/tex] ( cross- multiply )
50x = 400 ( divide both sides by 50 )
x = 8
The shadow cast by the pole is 8 ft
