what is the value of x?
[tex]x^2=40^2+9^2\\x^2=1600+81\\x^2=1681\\x=\sqrt{1681}=41[/tex]
To solve this you must use Pythagorean theorem:
[tex]a^{2} +b^{2} =c^{2}[/tex]
a and b are the legs (the sides that form a perpendicular/right angle)
c is the hypotenuse (the side opposite the right angle)
In this case...
a = 9
b = 40
c = x
^^^Plug these numbers into the theorem
[tex]9^{2} +40^{2} =x^{2}[/tex]
simplify
81 + 1600 = [tex]x^{2}[/tex]
1681 = [tex]x^{2}[/tex]
To remove the square from x take the square root of both sides to get you...
41 = x

If a cone has the same radius and height as a cylinder, the volume of the cone is (one fourth, one third, half, or two thirds) the volume of the cylinder. If a cylinder and a sphere have the same radius and the cylinder’s height is twice its radius, then the volume of the sphere is (one fourth, one third, half, or two thirds) the volume of the cylinder.
The volume of the cone is one third of the volume of the cylinder when they have the same radius and height.
The volume of the sphere is two thirds the volume of the cylinder when the sphere and the cylinder have the same radius and the height of the cylinder is twice its radius.
If a cone has the same radius (r) and height (h) as a cylinder, then the volume of the cone is one third the volume of the cylinder.
This can be determined using the formula for the volume of a cone, which is V = (1/3)πr²h, compared to the volume of a cylinder, which is V = πr²h. Since we have the same 'r' and 'h' for both, the cone's volume will be one third of the cylinder's.
Similarly, if a cylinder and a sphere have the same radius and the cylinder’s height is twice its radius, we can say h = 2r. Thus, the volume of the sphere is calculated to be V = (4/3)πr³.
On the other hand, the cylinder's volume with h=2r would be V = πr²(2r) = 2πr³. The sphere's volume is two thirds of the cylinder's volume, because (4/3)πr³ is two thirds of 2πr³.
using the side lengths determine whether the triangle is acute obtuse or right 24 30 18
Answer:
It is a Right Triangle.
Step-by-step explanation:
30^2 = 900
24^2 = 576
18^2 = 324
576 + 324 = 900
This satisfies the Pythagoras theorem so it is a Right Triangle.
Answer:
It's a right triangleStep-by-step explanation:
For a ≤ b ≤ c:
if a² + b² = c², then a triangle is a right triangle
if a² + b² < c², then a triangle is an obtuse triangle
if a² + b² > c², then a triangle is an acute triangle.
We have a = 18, b = 24, c = 30. Substitute:
18² + 24² = 324 + 576 = 900
30² = 900
18² + 24² = 30² → a² + b² = c²

The paragraph below comes from the rental agreement Susan signed when she opened her account at Super Video.
"All rentals are due back by midnight of the due date as printed on the transaction receipt. Any rental not received by midnight on the day it is due is subject to a late charge of $1.50 for each day it is late. Any rental not returned by the fifth day after the due date will be transferred to a sale. The Customer will then be required to pay the purchase price of the item in addition to five (5) days of late fees. The Customer will not be required to return the product once the total balance is paid."
As of today, Susan's movie is currently five days late. She knows that if she doesn't get the movie back tonight, she will be charged $9.99, the purchase price of the movie, plus five days' worth of late fees. A round trip cab ride to the video store will cost about $10.
Which of the following statements is true?
a.
Taking a cab to return the movie is the cheapest action. Susan should call a cab.
b.
It would cost about the same to keep or return the movie. Susan should keep it.
c.
Keeping the movie and paying the purchase price and late fees is the cheapest option.
d.
If Susan returns the movie, she should not have to pay late fees. She should return it.
Answer:
option B
Step-by-step explanation:
Given:
per day late costs= 1.50
Purchase price= 9.99
A round trip cab ride to the video store will cost = 10
5 day late cost= 5(1.50)
= 7.50
Payment after 5 day late= 5 day late cost + Purchase price
= 7.50 + 9.99
= 17.49
If she gets a cab, then total payment= 10 + 7.50
= 17.50
Hence both costs almost the same, option B is true
b.
It would cost about the same to keep or return the movie. Susan should keep it!

Find the probability of each event. There are 4 red marbles, 2 black marbles, and 2 green marbles in a box. P(red) = P ( red or black) =
Answer: P(red): 1/2
P(red or black):3/4
Step-by-step explanation: Count the total number of marbles. There are 8. Since there are 4 red marbles out of the 8, put this into a fraction. It will be 4/8, but simplify to 1/2. The P(red) is 1/2.
Since there are 4 red marbles and 2 black marbles, add them. There are 6 out of the 8 marbles. The fraction is 6/8 simplify to 3/4. The P(red or black) is 3/4.
The probability of choosing a red marble from the box is 0.5 and the probability for choosing either a red or black marble is 0.75.
Explanation:The subject of this question refers to calculating probabilities which is a concept in Mathematics, specifically in the scope of Statistics. To calculate the probability of an event, we need to know the total amount of outcomes and the amount of favorable outcomes. In the context of the question, these outcomes are represented by marbles.
First, we need to add the total number of marbles, which is 4 red + 2 black + 2 green = 8 marbles in total.
To find the probability of picking a red marble, we divide the number of red marbles by the total number of marbles. Hence, P(red) = 4/8 or 0.5.
To find the probability of picking a red or black marble, we add the number of red and black marbles and divide by the total number of marbles. Hence, P (red or black) = (4 red + 2 black) / 8 total = 6/8 or 0.75.

what is 20% of 50?
A.) Percent=20%, Amount =50, Base =unknown
B.) Percent=50%, Amount =unknown, Base= 20
C.) percent= 20%, Amount=unknown, Base =50
D.) Percent=unknown, Amount =20, Base= 50
20% of 50 is found by multiplying the base (50) by the decimal equivalent of the percent (0.2). The calculation yields an amount of 10, which indicates that 20% of 50 is 10.
Calculating percents involves using the basic equation that relates the percent, the base (also called 'whole' or 'total'), and the amount (or 'part'). The equation can be represented as percent = (amount/base) imes 100. To find what is 20% of 50, we use this equation, where the percent is known (20%) and the base is known (50), but the amount is what we are looking for.
First, let's convert the percent to a decimal to make the calculation easier: 20% = 20/100 = 0.2. Then, we multiply the base (50) by the decimal form of the percent (0.2): 50 x 0.2 = 10. So, 20% of 50 is 10.
Therefore, the correct representation relating the Percent, Amount, and Base in this problem is option A) Percent=20%, Amount=50, Base=unknown, since we're calculating the amount based on the known percent and base.
Answer:
C.) percent= 20%, Amount=unknown, Base =50
Step-by-step explanation:
20% is the percent
50 is the amount
20% of 50 is the unknown. This is the amount.
20% of 50 = 0.2 × 50 = 10

What is the value of f(x) = 9x when x = -2? A. 1 81 B. 81 C. 1 18 D. 18
Answer:
Step-by-step explanation:
The correct answer would be -18
To solve this, you would substitute x with the x value, which in this case is -2
That would make it so f(x)= 9(-2)
9*-2=-18
Therefore f(x)=-18
Note that f(x) is another way to write y, therefore...
y = 9x
To solve for this plug -2 in for x in this equation like so...
y = 9 * -2
When a positive number is being multiplied with a negative number the answer will be negative.
y = -18
C. is the answer (assuming that you meant to write -18 instead of 1 18)

7a3+56b3 factorize it plsss
Answer:
7(a + 2b)(a² - 2ab + 4b²)
Step-by-step explanation:
Given
7a³ + 56b³ ← factor out 7 from each term
= 7(a³ + 8b³) ← sum of cubes which factors in general as
a³ + b³ = (a + b)(a² - ab + b²)
8b³ = (2b)³ ⇒ b = 2b
a³ + 8b³ = (a + 2b)(a² - 2ab + (2b)²) = (a + 2b)(a² - 2ab + 4b²)
Hence
7a³ + 56b³ = 7(a + 2b)(a² - 2ab + 4b²) ← in factored form
I have a right triangle. The hypotenuse is 12. The base is 7 and the other side is 9.7. The sin(x) is 0.014. Cos(x) is 0.99 and tan(x) is 0.02. What is the measure of angle x?
Answer:
[tex]\sin(x)=\frac{\sqrt{95}}{12}=0.8122[/tex]
[tex]\cos(x)=\frac{7}{12} \approx .5833[/tex]
[tex]\tan(x)=\frac{\sqrt{95}}{7} \approx 1.3924[/tex]
[tex]x=\sin^{-1}(\frac{\sqrt{95}}{12}) \approx 54.3147[/tex] degrees.
I don't know what you want to round to but I can tell you are rounding...
Step-by-step explanation:
Soh Cah Toa is the acronym we will use to help us solve this.
This says sine is opposite over hypotenuse.
It also says cosine is adjacent over hypotenuse.
And finally tangent is opposite over adjacent.
Note: Opposite and adjacent can change depending on how you are looking at the triangle, like which angle you are referring to.
Let's look at x:
The side that is opposite, not touching, the angle whose measurement is x, is the side that has measurement [tex]\sqrt{95} \approx 9.7[/tex].
I see you already found this measurement. This is really good. I might use the exact value for now and round at the end.
The side that is the hypotenuse no matter the angle you are referencing is always going to be opposite the angle whose measurement is 90 degrees. It is also the longest side (since it is opposite the largest angle). This side has measurement 12.
The hypotenuse will be one of the sides touching your angle you are referencing. The other side that is touching your angle is the adjacent side. This side has measurement 7.
Anyways let's plug into the definitions we had above:
[tex]\sin(x)=\frac{\sqrt{95}}{12}[/tex] (O/H)
[tex]\cos(x)=\frac{7}{12}[/tex] (A/H)
[tex]\tan(x)=\frac{\sqrt{95}}{7}[/tex] (O/A)
Now we can solve anyone of these for x.
Take your pick.
[tex]\sin(x)=\frac{\sqrt{95}}{12}[/tex]
[tex]x=\sin^{-1}(\frac{\sqrt{95}}{12})[/tex]
[tex]x=54.3147[/tex] degrees.

From a total yearly budget of

space. What is the ratio of dollars
spent on office space to dollars spent
on other costs?
A. 12:1
B. 11:1
C
Answer:
I think it would be 11:1.
Step-by-step explanation:
360,000 / 30,000 = 12
11/12 of the yearly budget was used on other costs
1/12 of the yearly budget was used for leasing office
space.
Answer:
Step-by-step explanation:
Okay so I may be wrong BUT since it's asking for the other costs, I'm assuming we're subtracting the $30,000 from the $360,000 first. Therefore the original ratio would be 30,000: 330,000 which is simplified to 1:11 ($ on office space: $ on other costs)
Fuel economy estimates for automobilos built in a certain yoar predicted a mean of 26.8 mpg and a standard deviation of 72 mpg for highway driving. Assume that a normal distribution can be applied. Within what
range are 99.8% of the automobiles?
Answer:
range=u ± 3.09 sd
Step-by-step explanation:
Given:
mean, u= 26.8 mpg
standard deviation, sd=72 mpg
% contained in interval = 99.8%
the interval for 99.8% of the values of a normal distribution is given by
mean ± 3.09 standard deviation= u ± 3.09 sd
=26.8 ± 3.09(72)
=26.8 ± 222.48
= 249.28 , -195.68
range=u ± 3.09 sd = 249.28 , -195.68 !
Mary, Chau, and David have a total of $87 i their wallets. Marry has 9$ more than Chau. David has two times what Mary has. How much do they have in each wallet?
Answer:
Mary = 24
Chau = 15
David = 48
Step-by-step explanation:
The formula is
Mary + Chau + David = 87
And we know that
Chau = Mary - 9
David = Mary * 2
So when we fill this in
Mary + Mary - 9 + Mary * 2 = 87
4Mary - 9 = 87
4Mary = 96
Mary = 24
Chau = Mary - 9 = 15
David = Mary * 2 = 48
Final answer:
The problem is solved using basic algebra, yielding Chau has $15, Mary has $24, and David has $48, all adding up to the total amount of $87.
Explanation:
The question involves a three-person word problem focusing on algebraic relationships and equation solving. Mary, Chau, and David have a total of $87 in their wallets. Mary has $9 more than Chau, and David has twice what Mary has. To find out how much each person has, we'll let 'c' represent the amount that Chau has.
Accordingly, Mary has c + $9, and David has 2(c + $9). Together, they have a total of c + (c + $9) + 2(c + $9) = $87. Simplifying this, we get 4c + $27 = $87. Subtracting $27 from both sides gives us 4c = $60. Dividing both sides by 4, we find that Chau has $15.
Now, since Mary has $9 more than Chau, Mary has $24 ($15 + $9). David, having twice what Mary has, possesses $48 (2 x $24). These amounts add up to the total of $87.

What does x ^2 + y^2 = 9 mean? What about x ^2 + y ^2 = 0 ? Can a circle have a radius of − 3 ? Why or why not?
Answer:
See below.
Step-by-step explanation:
Compare our equation with one standard form of a circle:
x^2 + y^2 = r^2 where r = the radius.
So x^2 + y^2 = 9 is the equation of a circle with it's center at the origin and it's radius is 3 units.
x^2 + y^2 = 0 is not a circle because r = 0 ( a radius of 0). A circle of radius 0 is really a point!!
The value of the radius of a circle must be positive so it cannot have a radius of -3.
Answer
[tex]x ^{2} + {y}^{2} = r^{2} [/tex]
since all the terms are squared so there can be a negative number
but in number line
...... -4,-3,-2,-1,0,1,2,3.......
as we know negative sign indicates only the direction so -3 means in which coordinates will it lie.
.
.
.
[tex] {x}^{2} + {y}^{2} = 9[/tex]
it means the origin is (0,0) and radius 3
Suppose you buy a CD for $500 that earns 2.5% APR and is compounded quarterly. The CD matures in 3 years. How much will this CD be worth at maturity?
Answer:
A=$538.82
Step-by-step explanation:
We're going to use the compounded interest formula:
A=P(1+r/n)^n*t
Where,
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = t is the amount of time at which you're checking how much it's worth (yrs)
Using this information, we can use:
A=500(1+0.025/4)^3*4
A=500(1+0.00625)^12
A=500(1.00625)^12
A=500(1.07763259886)
A=538.82

Answer:
4
Step-by-step explanation:
-5x/6=-10/3
or..5x/6=10/3
or..X/2=2
so X=4
Answer:
x = 4
Step-by-step explanation:
note that - [tex]\frac{5}{6}[/tex] x = [tex]\frac{-5x}{6}[/tex], hence
[tex]\frac{-5x}{6}[/tex] = [tex]\frac{-10}{3}[/tex] ( cross- multiply )
- 15x = - 60 ( divide both sides by - 15 )
x = [tex]\frac{-60}{-15}[/tex] = 4, that is
x = 4
how do you convert 17 1/6 to a 3 decimal place
Answer:
17.167 rounded
Step-by-step explanation:
17+(1/6)
17+0,166
17.167
well, firstly convert the mixed fraction to improper fraction, and then simply divide the numerator by the denominator and round as needed.
[tex]\bf \stackrel{mixed}{17\frac{1}{6}}\implies \cfrac{17\cdot 6+1}{6}\implies \stackrel{improper}{\cfrac{103}{6}}~\hfill \stackrel{\textit{to a decimal}~\hfill }{103\div 6 = 17.166\overline{6}}\implies \stackrel{\textit{rounded up}}{17.167}[/tex]
