Answer:
t = 6.77 s
Step-by-step explanation:
Given that,
A drop of paint falls from a rafter that is 225 feet above the ground.
We need to find the time when the paint hit the ground. Let the time be t.
Using the second equation of kinematics i.e.
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
Where
u = 0 (initial velocity is 0 as it was at rest)
a = g
So,
[tex]225=\dfrac{1}{2}\times 9.8t^2\\\\t=\sqrt{\dfrac{2\times 225}{9.8}} \\\\t=6.77\ s[/tex]
So, it will hit the ground at 6.77 s.
Solve for x...............
Answer:
x = 12 degrees
Step-by-step explanation:
They all have to add up to 360, so:
[tex]5x + 4 + 4x+9+7x+4+9x-6+4x+1=360\\29x + 12 = 360\\29x = 348\\x = 12[/tex]
HELP HOW DO YOU DO THIS
Answer:
X = 49
Step-by-step explanation:
The top angle that measures 126° is a mirrored version of the angle measuring (x + 77)°. The means the angle, (x + 77)°, has to measure 126°. So, to get x you have to subtract 126 by 77 and that gives you 49.

Azim wants to buy a tablet computer that is priced 180.50 if the sales tax rate on the computer is 8% how many dollars and cents will Azim spend on the sales tax only
Answer: 98.1%
Explanation:
A 10% sale means that the post-sale price of the item is now 90%, or 0.9 of the original cost of the item. We then apply 9% sales tax by multiplying the 0.9 by 109%, or 1.09. 0.9 * 1.09 = .981, so the total cost of the item is 98.1% of the original pre-sale sticker price.
For percentage problems that do not deal with a specific starting number, it is always helpful to plug in 100 for the starting number. Here, we would then have a post-sale price of 90 dollars, and if we calculate the sales tax for the 90-dollar item it would be 90 * 0.09 = $8.10. THis gives us a total cost of 90 + 8.10 = $98.10, or 98.1% of the original 100-dollar price.

marbles numbered from 1 to 12 are put in a bag. if marbles are not put back into the bag after being drawn, what is the probability of drawing two prime numbers in a row?
Answer:
[tex]Probability = \frac{1}{11}[/tex]
Step-by-step explanation:
Given
Marbles = 12
Selection without replacement
Required
Determine the probability of selecting 2 primes
Between 1 and 12, the prime digits is 4, and they are: 3, 5, 7 and 11
So, when the first marble is picked, the probability that it will be prime is:
[tex]P(First) = \frac{4}{12}[/tex]
Now there are 3 primes left and 11 marbles in total. So, the probability of selecting another prime is:
[tex]P(Second) = \frac{3}{11}[/tex]
The required probability is:
[tex]Probability = P(First) * P(Second)[/tex]
[tex]Probability = \frac{4}{12} * \frac{3}{11}[/tex]
[tex]Probability = \frac{1}{11}[/tex]
What is the period of 1-sin 2πx/3? Please explain.
Answer:
Notice, period of function sin(kx) is 2π/k where k is constant (coefficient of x ) since coefficient of x in sin(2πx/3) is k=2π/3 hence the period of sin(2πx/3) is 2π/(2π/3)=3

A, B, and C lie on a straight line.
Given that angle y= 118 degrees and angle z =107 degrees work out x.
Step-by-step explanation:
m∠B = 180° - y°
= 180° - 118°
= 62°
x° = 180° - (m∠B + z°)
x° = 180° - (62° + 107°)
x° = 180° - 169°
x° = 11°
i don't know, it was correct or no. Because i thought this question is looking for the valuable of x.

A local country club has a membership of 600 and operates facilities that include an 18-hole championship golf course and 12 tennis courts. Before deciding whether to accept new members, the club president would like to know how many members use each facility. A survey of the membership indicates that 75% use the golf course, 50% use the tennis courts, and 5% use neither of these facilities. One club member is chosen at random. What is the probability that the member uses the golf course but not the tennis courts
Answer:
0.45 = 45% probability that the member uses the golf course but not the tennis courts
Step-by-step explanation:
I am going to solve this question using the events as Venn sets.
I am going to say that:
Event A: Uses the golf courses.
Event B: Uses the tennis courts.
5% use neither of these facilities.
This means that [tex]P(A \cup B) = 1 - 0.05 = 0.95[/tex]
75% use the golf course, 50% use the tennis courts
This means, respectively, by:
[tex]P(A) = 0.75, P(B) = 0.5[/tex]
Probability that a member uses both:
This is [tex]P(A \cap B)[/tex]. We have that:
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]
So
[tex]P(A \cap B) = 0.75 + 0.5 - 0.95 = 0.3[/tex]
What is the probability that the member uses the golf course but not the tennis courts?
This is [tex]P(A - B)[/tex], which is given by:
[tex]P(A - B) = P(A) - P(A \cap B)[/tex]
So
[tex]P(A - B) = 0.75 - 0.3 = 0.45[/tex]
0.45 = 45% probability that the member uses the golf course but not the tennis courts

310
250
300
370
There are 310 bacteria are present after 10 hours.
The first is the correct option.
What is Exponential Growth?An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.
y = a(1+r)ˣ,
where a is the initial population and r is the rate in decimals and x is the time period.
Given:
The population of a bacterial culture grows at a rate of 4.5% every hour.
If there were 200 bacteria at the start,
then the number of bacteria after 10 hours are,
y = 200(1 + 0.045)¹⁰
y = 310.6
Therefore, 310.6 bacteria are present after 10 hours.

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in 39 minutes ? In 1 hour ?
Step-by-step explanation:
1 and 3/4 miles ???? miles
-------------------- = ---------------------
2 and 1/3 minutes 39 minutes
Cross multiplies:
(1 and 3/4) x 39 = (2 and 1/3) x ?
7/4 x 39/1 = 7/3 x ?
273/4 = 7/3 x ?
? = 273/4 * 3/7 = 39*3/4 <---- 7 x 39 = 273

Answer: 14.967
Step-by-step explanation:
Use Pythagorean Theorem to find the missing length.
a² + b² = c²
x² + 10² = 18²
x² + 100 = 324 [Subtract 100 from both side]
x²= 224
√x² = √224 [solve the square root from both sides]
x ≈ 14.967
2t + 4(4 + 10t)

Answer:
=42t+16
Step-by-step explanation:
=2t+(4)(4)+(4)(10t)
=2t+16+40t
=2t+16+40t
=(2t+40t)+(16)
=42t+16
Simplify the expression
2t + 4(4 + 10t)
Simplifying
y = 2t4 + -10t2 + 13
Reorder the terms:
y = 13 + -10t2 + 2t4
Solving
Solving for variy = 13 + -10t2 + 2t4
able 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 13 + -10t2 + 2t4
Hence the information I've given you, we can now state that the answer is
