A cone has a volume of 301.44 cubic yards and a radius of 6 yards. What is its height?
Answer:
h≅ 8 yards
Step-by-step explanation:
Given data
Volume of cone= 301.44 cubic yards
Radius of cone= 6 yards
Required
The Height of the cone
The expression for the volume of a cone is given as
V= 1/3πr^2h
Substitute
301.44= 1/3* 3.142*6^2*h
301.44= 37.704*h
Divide both sides by 37.704
h= 301.44/37.704
h= 7.99
h≅ 8 yards
Find the surface area and volume of the prisim it has 5cm 12cm 13cm and 28cm The surface area of the prism is (blank)cm2 The volume of the prism is (blank)cm3 pls help i need this quick!
Answer:
A = 1124 cm²
V = 840 cm³
Step-by-step explanation:
Assuming the prism is a triangular prism,
Applying,
V = 1/2bhL.................. Equation 1
Where V = volume of the prism, L= lenght of the prism, b = base of the triangle, h = height of the triangle
From the question,
Given: L = 28 cm, 12 cm, h = 5 cm
Substitute these values into equation 1
V = (5×12×28)/2
V = 840 cm³
Surface area (A) = bh+(a+b+c)L
A = (5×12)+(13+13+12)28
A = 60+1064
A = 1124 cm²

Tyler and Bethany have 240 feet of fencing with which to build a garden. Tyler wants the garden to be in the shape of a square, while Bethany wants it to be rectangular with a length of 50 feet and a width of 70 feet. Which design would give the maximum area for the garden? Explain.
Bethany’s design would give the larger garden because the area would be 3,500 ft2.
Tyler’s design would give the larger garden because the area would be 3,600 ft2.
Bethany’s and Tyler’s designs would give a garden with the same area.
Bethany’s and Tyler’s designs are not possible with the given amount of fencing.
Answer:
Step-by-step explanation:
Tyler's square is going to be 60 feet on each side. That is 3600 square feet.
Bethany can build a rectangle to her shape. It will be 240 feet of fencing. But it will give only 3500 square feet.
A is wrong. A square maximizes the area.
B is correct.
C The areas are not the same. C is wrong.
D is wrong. Both fence proposals work.
Answer:
B is correct
Explanation:
Tyler's square is going to be 60 feet on each side. That is 3600 square feet.
Bethany can build a rectangle to her shape. It will be 240 feet of fencing. But it will give only 3500 square feet.

you flip a coin,
What is P(heads)
write your answer as a percentage
The percent chance of it landing on heads is 50% and it landing on tails is 50%
So chances of it landing on heads is 50%
Answer:
50%
Step-by-step explanation:
since it is a 2 sided coin , and you flip it once, each side has a 50% chance of being landed on. there isn’t any more chance on one side than the other, so it would be 50% probability
Analyze the diagram below and complete the instructions that
Find the value of x and the value of y.
A. x=15, y=10√3
B. x 20, y=10√3
C. x=20√3 y=5√3
D. x =15, y = 5√3
9514 1404 393
Answer:
D. x = 15; y = 5√3
Step-by-step explanation:
You don't need to know any trig to select the correct answer. You only need to know that the lengths of both sides must be less than the length of the hypotenuse. It is also helpful to know that √3 is about 1.732, so 10√3 ≈ 17.32.
Since x < 10√3, only answer choices A and D are viable.
Since y < 10√3, only answer choice D is viable.
_____
If you want to solve this using trig relations, you can recall that the sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. This means short side y is half the length of the hypotenuse 10√3, so y = 5√3. It also means longer side x is √3 times y, so is x = (5√3)√3 = 5·3 = 15.
x = 15; y = 5√3

Which fraction
is equivalent to 6/2
1/3
Answer:
[tex]\frac{3}{1}[/tex]
Step-by-step explanation:
[tex]\frac{3}{1}[/tex] is equivalent to [tex]\frac{6}{2}[/tex] because 3 x 2 = 1 x 6 = 6. 93 is equivalent to [tex]\frac{6}{2}[/tex] because 9 x 2 = 3 x 6 = 18. 124 is equivalent to [tex]\frac{6}{2}[/tex] because 12 x 2 = 4 x 6 = 24.
Eduardo spent 4 minutes on the phone while routing 2 phone calls. In all, how many phone calls does Eduardo have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
Answer:
8 phone calls
Step-by-step explanation:
Eduardo spent 4 minutes on the phone while routing 2 phone calls. In all, how many phone calls does Eduardo have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
From the above question:
4 minutes = 2 phone calls
16 minutes = x
Cross Multiply
4 minutes × x = 16 minutes × 2 phone calls
x = 16 minutes × 2 phone calls/4 minutes
x = 8 phone calls
Therefore,
Eduardo has to route 8 phone calls to spend a total of 16 minutes on the phone

Please help me with this one.
Answer:
Step-by-step explanation:
Jackie you should know that the supplemental angles always add to 180° :)
That's like angles 1 & 2 or 55° & 1 . both are supplemental and add to 180°
Knowing this should make answering this pretty easy. :)
180 = ∠1 + 55
125 = ∠1
∠3 =∠1
∠2 = 55°
since line g is parallel to f , we know all the angles in the same places of line f are identical... got it?
A rectangle is placed around a semicircle as shown below. The length of the rectangle is 14 m . Find the area of the shaded region. Use the value 3.14 for , and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
21.07 m²
Step-by-step explanation:
Please find the complete question in the attached image
Area of shaded region = area of rectangle - area of semicircle
Area of semicircle = [tex]\frac{1}{2}[/tex]πr²
π = 3.14
r = radius = 14/2 = 7m
the diameter of the semicircle is 14m , thus the radius would be half of the diameter
(1/2) x 3.14 x 7² = 76.93 m^
Area of a rectangle = length x width
width = radius of semicircle = 7
14 x 7 = 98 m²
Area of shaded region = 98 m² - 76.93 m^ = 21.07 m²

Help plsss anyonnne plsss
Answer:
0.50
Step-by-step explanation:
The question states at least 2 which means 2 or more.
The only applicable numbers to look at would be 2 and 3.
First of all we find 2 since it's missing.
Now all probability distributions must add up to 1.
As we can see there are 0.20, 0.30 and 0.40 which is equal to 0.90. Therefore 1 - 0.90 = 0.10 which would be 2.
Hence, the peobability that x is at least 2 is 0.10 + 0.40 = 0.50.

Two no's are in the ratio 5:3 if they differ by 18, what are the numbers
Let us consider the ration of two numbers be x
The two numbers are 5x and 3x
Since two numbers differ by 18, we can write the equation
5x – 3x = 18
2x = 18
x= 9
Therefore the two numbers are
5x = 5 x 9 = 45
and
3x = 3 x 9 = 27
∴ The two numbers are 45 and 27.
Two solutions of different concentrations of acid are mixed creating 40 mL of a solution that is 32% acid. One-quarter o...
Answer:
See explanation below
Step-by-step explanation:
Question is incomplete. Here's the whole question:
"Two solutions of different concentrations of acid are mixed creating 40 ml of a solution that is 32% acid. one-quarter of the solution is made up of a 20% acid solution. the remaining three-quarters is made up of a solution of unknown concentration, c. equation can be used to determine c, the unknown concentration?
a) 30c + 10(0.2) = 40(0.32)
b) (c) + (0.2) = 40(0.32)
c) (c)( (0.2)) = 40(0.32)
d) 30(c)(10(0.2)) = 40(0.32)"
With this, we can now solve the question.
We have a solution that was made mixing2 different solutions of acid. In this case, we can assume the following:
Solution 1 = 40 mL 32% acid
Solution 2 = 1/4 solution 1, 20% acid
Solution 3 = 3/4 solution 1, c% acid.
Thus we can say:
Solution 1 = Solution 2 + Solution 3 (1)
Now, 1/4 of the volume of solution 1, means that we use 10 mL of a 20%acid, and the remaining 30 mL is the unknown acid.
With this, we can discart option b) and c) because these option are not considering the volume of solution 3 used. Option d is not doing any sum, only multiplications, so, this is not the option to use. We can easily say it's option a, but let's prove it.
In general terms, concentrations and volume are related, and if we have two solutions, the information of these two solutions must be conserved in the resulting solution. In other words:
M₁V₁ = M₂V₂
According to this, the concentration of the unknown acid would be:
30c + 0.2*10 = 40(0.32)
30c + 2 = 12.8
30c = 10.8
c = 0.36
Which means that the concentration of the acid is 36%
Hope this helps

(2/5)^-2(-3)^4
What is the equivalent?
Answer:
-8100
Step-by-step explanation:
(2/5)^-2(-3)^4
Given data
and second term
The first term= (2/5)^-2 and
Second term=(-3)^4
Simplify the first term
(2/5)^-2= 2^-2/ 5^-2= 1/2^2 * 1/5^2
=1/4/ 1/25
=1/4*25/1
=100
Simplify the second term
=(-3)^4
= -81
Hence, 100*81
=-8100
