A container that holds wheat is shaped like a cone. The diameter of the base of the container is 21 and 3/4 feet, and the height of the container is 10.3 feet.
Which measurement is closest to the volume of the container in cubic feet?
Answer choices:
A. 15,307.55 ft3
B. 1,275.63 ft3
C. 5,102.52 ft3
D. 3,826.89 ft3
Answer:
answer is b.
Step-by-step explanation: use formula
V=1/3(hπr²)
so using this formula gives us 1275.62897 but rounded off gives us 1,275.63 ft3
ok the diameter is 21 3/4ft i converted it to a decimal, 21.75ft so to get the radius i 21.75ft/2= 10.875ft
ok to continue
V=1/3(hπr²)
V=1/3(3.14*10.875ft)h
V=1/3(118.265625ft)
V=1/3(118.265625 ft)10.3ft
V=1275.62897 which rounded=1,275.63 ft3

The graph of an exponential function passes through the points (1,1/16) and (3,1/64) . Write an equation for the function in the form y=a*b^x
Answer:
y=3,1*64^1,1/16
Step-by-step explanation:
The exponential equation will be written as, [tex]y=(\dfrac{1}{8})(\dfrac{1}{2})^x[/tex].
What is an exponential expression?Powers can simply be expressed in concise form using exponential expressions. The exponent shows how many times the base has been multiplied. Since 2 is the "base" and 5 is the "exponent,"
It can be represented as 2x2x2x2=25 for the number 32. This phrase should be understood as "two to the fifth power."
Given that the graph of an exponential function passes through the points (1,1/16) and (3,1/64).
The values of a and b will be calculated as,
1/16 = ab
1/64 = ab³
1/64 = ab x b²
1/64 = 1 / 16 x b²
b = 1 / 2
a = 1 / 8
The exponential equation will be written as,
[tex]y=(\dfrac{1}{8})(\dfrac{1}{2})^x[/tex].
Therefore, the exponential equation will be written as, [tex]y=(\dfrac{1}{8})(\dfrac{1}{2})^x[/tex].

Answer:
12 ft
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 41.5°
Opposite = 8 ft
Length of handrail =?
We can obtain the length of the handrail by calculating the Hypothenus. This can be obtained as follow:
Angle θ = 41.5°
Opposite = 8 ft
Hypothenus =?
Sine θ = Opposite /Hypothenus
Sine 41.5 = 8 / Hypothenus
0.6626 = 8 / Hypothenus
Cross multiply
0.6626 × Hypothenus = 8
Divide both side by 0.6626
Hypothenus = 8 / 0.6626
Hypothenus = 12 ft
Thus, the Lenght of the handrail is 12 ft

The average grade for an exam is 74, and the standard deviation is 7. The grades are curved to follow a normal distribution.
What is the probability that the grade of a randomly selected students score is more than 60?
Answer:
0.9772 = 97.72% probability that the grade of a randomly selected students score is more than 60.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The average grade for an exam is 74, and the standard deviation is 7.
This means that [tex]\mu = 74, \sigma = 7[/tex]
What is the probability that the grade of a randomly selected students score is more than 60?
This is 1 subtracted by the pvalue of Z when X = 60. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{60 - 74}{7}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a pvalue of 0.0228
1 - 0.0228 = 0.9772
0.9772 = 97.72% probability that the grade of a randomly selected students score is more than 60.

The legs of an isosceles right triangle are 3 feet long. How long is the hypotenuse?
Answer:
Step-by-step explanation:
Since its isosceles right triangle, then 2 sides are going to be the same. There are 2 legs that are in any triangle, they give us 1 leg so now we know what the other leg is. Now the formula for finding hypotenuse is a2+b2=c2.
[tex]3^{2}+3x^{2} =c^{2}[/tex] 3 squared is 9, so 9+9=18
now we have c but we arent done so now we find the square root, [tex]\sqrt{18}[/tex]. Which is [tex]3\sqrt{2}[/tex] or 4.24.

What is an equation?An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of scholars who chose to go to the amusement park and y represent the number of scholars who chose to go to the zoo.
scholars who chose to go to the amusement park is 140% of the number of scholars who chose to go to the zoo. Hence:
x = 140% of y = 1.4y
Also, There are 264 scholars in the sixth grade, hence:
x + y = 264
1.4y + y = 264
y = 110
x = 1.4(110) = 154
154 scholars chose to go to the amusement park.

A polyhedron (not regular) has 10 vertices and 5 faces. How many edges does it have?
Answer:
13 edges
Step-by-step explanation:
Euler's formula for polyhedra states that
F + V - E = 2 ( F is faces, V is vertices and E is edges ) , then
5 + 10 - E = 2
15 - E = 2 ( subtract 2 from both sides )
13 - E = 0 ( add E to both sides )
13 = E
The polyhedron has 13 edges
Oliver had m dollars to spend on a backpack for the new school year. The expression below represents the amount of money he had remaining after purchasing the backpack.
m - (y + 0.07y)
If his total purchase included the backpack and tax, which statement best describes y?
A.
The amount of money he had to spend on the backpack.
B.
The amount of tax for the backpack.
C.
The price of the backpack, including tax.
D.
The price of the backpack, not including tax.
Answer:
Option A
Step-by-step explanation:
Y is the amount of back pack
The total amount is represented by m
If Y is the cost of back pack purchased by Oliver, then 0.7 Y is the tax applicable on the purchase of back pack
Hence, the remaining cost would be total amount with Oliver minus the cost of back pack and the tax applicable on the purchase of back pack
Remaining cost = m - (y + 0.07y)
Hence, option A is correct
Two traffic lights operate independently. Your probability of being stopped at the first one is 0.4 and your probability of being stopped at the second one is 0.7. The probability at being stopped at the first light and second light is 0.3. What is your probability of being stopped at the first light or second light?Make sure to show your work. NEED HELP ASAP
Answer:
Most people found the probability of just stopping at the first light and the probability of just stopping at the second light and added them together. I'm just going to show another valid way to solve this problem. You can solve these kinds of problems whichever way you prefer.
There are three possibilities we need to consider:
Being stopped at both lights
Being stopped at neither light
Being stopped at exactly one light
The sum of the probabilities of all of the events has to be 1 because there is a 100% chance that one of these possibilities has to occur, so the probability of being stopped at exactly one light is 1 minus the probability of being stopped at both lights minus the probability of being stopped at neither.
Because the lights are independent, the probability of being stopped at both lights is just the probability of being stopped at the first light times the probability of being stopped at the second light. (0.4)(0.7) = 0.28
The probability of being stopped at neither is the probability of not being stopped at the first light, which is 1-0.4 or 0.6, times the probability of not being stopped at the second light, which is 1-0.7 or 0.3. (0.6)(0.3) = 0.18

Answer:
C) 4
Step-by-step explanation:
We observe that the top segments are in the same 3:4 ratio as the bottom segments. This means they are the same lengths: 3x = 12, 4x = 16. Either of these equations tells us x = 4.

Additional comment
In case you aren't convinced, you can solve this using the secant rule for segments and circles: the product of the lengths to the circle intercepts are the same for both secants.
12(12 +16) = 3x(3x +4x)
336 = 21x² . . . . . simplify

(5) + 2 = 7
2(5) + 3 = 13
13 * 7 = 91
Step-by-step explanation:
Given area = 91m²
length = 2x+3 m
breadth = x +2 m
we know,
Area = length x breadth
91 = (2x+3) x (x+2)
91 = 2x² + 4x + 3x + 6
91 = 2x² + 7x + 6
2x² + 7x - 85 = 0
(2x+17)(x−5)=0
2x+17=0 or x−5=0
x=−17/2 or x=5
