Given :
The height of a building is 1417 ft.
To Find :
How long would it take an object to fall to the ground from the top.
( Use the formula s = 16t² where s is the distance, in feet traveled by an object falling freely from rest in seconds. )
Solution :
Putting value of height in given equation, we get :
[tex]16t^2 = 1417\\\\t^2 = \dfrac{1417}{16}\\\\t^2 = 88.5625\\\\t = \sqrt{88.5625}\\\\t = 9.41 \ seconds[/tex]
Therefore, time taken by object to reach the ground is 9.41 seconds.

Answer:
third option
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
d = - 13 - (- 10) = - 16 - (- 13) = - 3
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 10 and d = - 3, then
[tex]a_{n}[/tex] = - 10 - 3(n - 1) = - 10 - 3n + 3 = - 7 - 3n
Thus the sum of the first 6 terms is represented by
∑ - 7 - 3n ( for n = 1 to 6 )

Today I am going to get my usual drink and some Pumpkin Bread. Which item is the better one to use my stars on? Explain why you think that is the better option.

Answer:
m ≤ 4250
Step-by-step explanation:
What we know:
Mr. Loureiro has to pay $25 plus 10 cents every mile.
The equation becomes 25 + 0.1x = 450
25 + 0.1x = 450
0.1x = 450 - 25
0.1x = 425
x = 4250
So, Mr. Loureiro can travel no more than 4250 mi. (m ≤ 4250)
A teacher offers gift cards as a reward for classroom participation. The teacher places the gift cards from four different stores into a bag and mixes them well. A student gets to select two gift cards at random (one at a time and without replacement). Each outcome in the sample space for the random selection of two gift cards is equally likely. What is the probability of each outcome in the sample space?
1/16
1/6
1/4
1/2
Answer:
1/6
Step-by-step explanation:
i took the test and my teacher explained this.
The probability of each outcome in the sample space = 1/2.
What is probability?
Probability is the chance of happening a situation or event.
Here, the probability to get a single gift card is 1/4.
A student can pick two cards, one at a time without any replacement.
Hence, the probability of the student to pick a second card is 1/3.
Hence, the probability of a student to pick two cards = 1/4 × 1/3 = 1/12.
Here, a student might select any of these combinations {(1, 2), (1, 3), (1, 4), (2, 3), (2, 4), (3, 4)}.
Therefore, the probability of each outcome in the sample space = 1/12 × 6 = 1/2.

The company plans to have the tanks painted after they are installed. Describe the effect that doubling the diameter has on the amount of paint needed to paint the tanks. What happens when the diameter is increased by a factor of 3?
Answer:
The effect of doubling the diameter is increased the area to paint as 4 times. So, paint needed is 4 times than it was before. And the area is increased by 9 times when the diameter is increased by a factor of 3. So, paint needed is 9 times than before.
Step-by-step explanation:
Please remember the concept
If side lengths are in the ratio a : b
Then the area are in the ratio of a^2 :b^2
The volume are in the ratio of a^3 :b^3,
When diameter is doubled, the area ratio becomes [tex]x^{2} :(2x)^{2}[/tex] which is simplified to [tex]x^{2} :4x^{2}[/tex]
So, the area is increased by 4 times.
According to this concept , the diameter is increased by the scale factor 3.
Let the diameter of tank is 'x', so the diameter becomes "3x"
So, it's area ratio would be [tex]x^{2} :(3x)^{2}[/tex]
If we simplify it we get [tex]x^{2} :9x^{2}[/tex]
We conclude that area to be increased by 9 times.

Okay so ur at a party and they have donuts, 5/25 of the donuts are eaten. What percent of them are left?
If it's not too much trouble could you explain how to solve it? If not I guess I'll live:(
Answer:
80%
Step-by-step explanation:
100%= 25/25. 1 donut = 5%. So you have 20 donuts left x 5.
Answer:
80% are left.
Step-by-step explanation:
So 100 donuts would be 100%. To get to 100 you need to multiply 25x4. Then you also need to multiply 5x4=20. Since it is the 5 that are eaten, you subtract 20 from 100 and get 80, so you are left with 80% of the donuts.

How much will Juan pay if it takes the electrician 6 1/2 hours to complete the job? (Vou should have 9 answers in question 2
Answer: a. c = 30 + 45h
b. $322.50
Step-by-step explanation:
A. Write a function that can be used to find the total charge, c, Juan will pay when the electrician works, h, hours.
This will be calculated as:
c = 30 + 45h
B. How much will Juan pay if it takes the electrician 6 1/2 hours to complete the job?
Using the expression,
c = 30 + 45h
c = 30 + 45(6 1/2)
c = 30 + 292 1/2
c = 322.50
Therefore, Juan will pay $322.50

Step-by-step explanation:
Over a one week period in the summer, the price of a gallon of gas increased from $2.35 to $2.82. By what percent did the price of gas increase over that week?
The percentage increase from $2.35 to $2.82 over the week in summer is 20%
Given Data
Initial Value = $2.35
Final Value = $2.82
We know that the expression for Percentage increase is given as
% Increase = Increment/Initial Value *100
% Increase = 2.82-2.35/2/35 * 100
% Increase =0.47/2/2.35 * 100
% Increase =0.2* 100
% Increase = 20%
Hence the percentage increase is 20%
