How much time does it take for the quarter to hit the water ???
Answer:
7 seconds
Step-by-step explanation:
y=-16t²+96t+112, where t is time and y is distance above water.
We are looking for t when y=0
-16t²+96t+112=0
t²-6t-7=0
(t-7)(t+1)=0
Either t=7 or t=-1.
Since we cant have negative time, the answer is t=7

Find the missing term in the
geometric sequence.
12,[ ? ],108
Answer: 36
Step-by-step explanation:
Knowing 12 most likely isn't the 1st term finding the formula will be unnecessary and difficult. Instead, divide 108, by 12. This will give you a multiplier of 3. Knowing this, divide 108 by 3, and you'll get 36. That is the missing term in the sequence.

Answer:
x = √146 = 12.1 (nearest tenth)
Step-by-step explanation:
Apply pythagorean theorem, c² = a² + b², where,
c = x
a = √82 km
b = 8 km
Plug in the values
x² = (√82)² + 8²
x² = 82 + 64
x² = 146
x = √146 = 12.1 (nearest tenth)

1.For each of 200 randomly selected cities, Gary recorded the number of churches in the
city (x) and the number of homicides in the past decade (y). He calculated the linear
correlation coefficient and was surprised to find a strong positive linear correlation for
the two variables. Does this suggest that building new churches causes an increase in
the number of homicides? Why do you think that a strong positive linear correlation
coefficient was obtained? Explain your answer with reference to the term lurking

Please answer all i need help Factor the expression using the GCF. 50x-60 Next one Factor the expression using the GCF. 16m+40 next one Factor the expression using the GCF.27-45c next one Factor the expression using the GCF.
Answer:
10(5x - 6).
8(2m + 5).
9(3 - 5c)
Step-by-step explanation:
Given that
50x-60
16m+40
27-45c
The greatest common factor is a measure of the highest number present inside, or common to all the numbers that were listed. To take this one at a time, we have....
50x - 60. The highest number common to both of them is 10, and thus, we have
50x - 60 = 10(5x - 6), and this is the solved part.
16m + 40. The greatest number that's present inside both numbers is 8, and thus we have
16m + 40 = 8(2m + 5) and this is the solved part.
27 - 45c. The greatest common number is 9, and as a result, we have
27 - 45c = 9(3 - 5c), and this is the solution we were searching for
Robin ran 1/2 of a mile. He finished with 2/3 of the race. how long is the whole race?
Answer: 3/4 mile
Step-by-step explanation:
To find the answer, you divide 1/2 by 2/3. You do KCC so it turns into 1/2 x 3/2. The final answer is 3/4.
So we know that Robin ran 1/2 of a mile and he finish 2/3 of the race.
To find the answer, you divide 1/2 by 2/3.
You do keep change change, so it turns into 1/2 x 3/2 which is 3/4.
Final result: 3/4

Answer:
Step-by-step explanation:
∠BAC = 180° - 75° = 105°
The sum of the angles of a triangle is 180°.
(3x+2) + (10x-5) = 75
13x-3 = 75
x = 6
∠B = 3x+2 = 20°
∠BCF = 10x-5 = 55°
Which of the following statements is true about systematic random sampling?
A- Systematic random sampling requires a finite population size.
B- Systematic random sampling catches all patterns present in the population.
C- Systematic random sampling can be used, even if knowledge of the entire population is not known.
D- The starting point can always be the first person seen, as long as the gap between the first and second person is a random number.
Systematic random sampling involves a selection technique in which samples are selected at fixed intervals. Hence, the true statement is "Systematic random sampling can be used, even if knowledge of the entire population is not known."
Systematic random sampling would fail to catch all patterns because the samples are selected at periodically at fixed intervals, hence, the possibility of missing pattern is very possible. Starting point could be at any point and hence, might not be the first sample in the population.However, without knowing the entire population size, systematic random samples could be selected from the population.

f(x) = 5x – 10 and g(x) = x – 16. Which of the following represents h(x) = f(x) + g(x)? h(x) = 6x – 16 h(x) = 6x – 26 h(x) = x – 26 h(x) = x – 16
Answer:
h(x)=6x-26
Step-by-step explanation:

g(x)=x-16
h(x)=f(x)+g(x)=(5x-10)+(x-16) = 6x-26
A candy bar that originally sold for $0.65 undergoes a 7% price increase each year. Find the new cost of the candy bar after 15 years. Round your answer to the nearest cent.
The new cost of the candy bar after 15 years is $
Answer:
10.4325
Step-by-step explanation:
For 1 year: (0.65) + (0.65)(0.07) = 0.6955
For 15 years: 0.6955 X 15 = 10.4325
All together: (0.65+(0.65*0.07))*15 = 10.4325
The new cost of the candy bar after 15 years is $1.8.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a candy bar that originally sold for $0.65 undergoes a 7% price increase each year.
Use Amount = Principal(1+R/100)ⁿ, where n is number of years.
Total amount = 0.65(1+7/100)¹⁵
= 0.65(1.07)¹⁵
= 0.65×2.759
= $1.8
Therefore, the new cost of the candy bar after 15 years is $1.8.
