Answer:
[tex]Distance = 880ft[/tex]
Step-by-step explanation:
Given
[tex]Speed = 20\frac{miles}{hour}[/tex]
[tex]Time = 30\ seconds[/tex]
Required
Determine the distance
To answer this question, we make use of speed-distance relationship
[tex]Speed = \frac{Distance}{Time}[/tex]
Make Distance the subject
[tex]Distance = Speed * Time[/tex]
[tex]Distance = 20 miles/hour * 30 seconds[/tex]
Convert seconds to hour
[tex]Distance = 20 miles/hour * \frac{30}{3600} hour[/tex]
[tex]Distance = 20 miles * \frac{30}{3600}[/tex]
[tex]Distance = \frac{20 miles * 30}{3600}[/tex]
[tex]Distance = \frac{600\ miles}{3600}[/tex]
[tex]Distance = \frac{1}{6} miles[/tex]
Convert to foot
[tex]Distance = \frac{1}{6} * 5280\ ft[/tex]
[tex]Distance = \frac{1* 5280\ ft}{6}[/tex]
[tex]Distance = \frac{5280\ ft}{6}[/tex]
[tex]Distance = 880ft[/tex]
A swimming pool has two pipes coming into it to fill it with water. One pipe takes 16 hours to fill it. The other takes 12 hours to fill it. How many hours will it take both pipes to fill the pool?
Answer:
8 hours
Step-by-step explanation:
8 hours because half of 16 is 8 and half of 12 is 6
If it takes 6 hours to fill one half then the other 2 hours would go to the other pipe making it 8 hours

3) A is between B and C. If BC= 8x + 5, AB= 2x + 4, and AC= 3x + 7, then
find AB
Answer:
AB = 8
Step-by-step explanation:
A is between B and C. If BC= 8x + 5, AB= 2x + 4, and AC= 3x + 7, then find AB
Step 1
Find x
BC = AB + AC
8x + 5 = 2x + 4 + 3x + 7
Collect like terms
8x - 2x - 3x = +4 + 7 - 5
3x = 6
x = 2
Step 2
Find AB
= AB= 2x + 4
AB = 2(2) + 4
AB = 4 + 4
AB = 8

Answer:
k = 0.2
A = (M / P₀) − 1
Step-by-step explanation:
dP/dt = kP
When t = 0, P = 1000 and dP/dt = 200.
200 = 1000k
k = 0.2
P = M / (1 + Ae⁻ᵏᵗ)
When t = 0, P = P₀.
P₀ = M / (1 + A)
1 + A = M / P₀
A = (M / P₀) − 1

Consider the equation 5x + 7 = 2x + 28. Your tasks to explain the steps you would take, in
order, to solve the equation for x. Imagine that you are writing this for someone who is learning
about this process for the first time. You would be as specific as possible and write in complete
sentences.
Answer:
x=7
Step-by-step explanation:
Step 1: Put the variables and constants on the same side and change their signs so it'll look like this 5x-2x = 28 - 7, you always move the smaller number to either the left or right depending on its position in the problem.
Step 2: solve each side normally like this, 3x = 21
Step 3: to get x by itself divide 3 on both sides and you should get x=7
Here's a run through of the steps
5x+7=2x+28
-7 -7(subtract 7 from both sides
5x=2x+28-7
-2x -2x(subtract 2x from both sides)
5x-2x=28-7
3x=21
3x/3 = 21/3 (divide 3 from both sides)
x=7

If sally has 90000000 apples and gives her freind sophie 1900 of them , and keeps 900 apples for her self hown many apples did she give to charity?1
Answer: 89,998,910
Step-by-step explanation: if she gives 1900 away and keeps 900 then I’m assuming she gives the rest away to charity and that would be 89,998,910 apples
Answer:
She gave 89997200 apples to charity
Step-by-step explanation:
90000000 - 1900 - 900 = 89997200
or
90000000 - (1900 + 900) = 89997200
Find the value of z such that 0.02 of the area lies to the right of z. Round your answer to two decimal places.
The value of z-score such that 0.02 of the area lies to the right of z would be 2.06.
Given that,
0.02 of the area lies to the right of z.
Now, for the value of z such that 0.02 lies to the right of z, we can make use of the standard normal distribution table.
Since to determine the value of z such that 0.02 of the area lies to the right, we need to find the z-score associated with the cumulative probability of (1 - 0.02) = 0.98
Now for the value of 0.98 in the standard normal distribution table, we find that the corresponding z-score is 2.06.
Therefore, the value of z, rounded to two decimal places, is 2.06.

zach says that the expressions 6x - 36 and 3(2x -12) are equivalent
Answer:
True
Step-by-step explanation:
When you distribute the 3, you get x(2x3)-(12x3)
2x3=6
12x3=36
so 6x-36

A rope that is 168 ft long is to be cut into three pieces such that the second piece is 6 ft less than three times the first, and the third is 2 ft more than two-thirds of the second. Find the length of the longest piece.
Answer:
Length of longest piece is 82 ft
Step-by-step explanation:
Let the measure of the second piece be x
First piece be y
second piece is 6 ft less than 3 times the first
x = 3y - 6
y = (x + 6)/3
3rd piece = 2 + 2/3 * x
= 2 + 2x/3
Adding all equals 168
we only add in terms of x
so we have;
x + (x + 6)/3 + 2 + 2x/3 = 168
Multiply through by 3
3x + x + 6 + 6 + 2x = 504
6x + 12 = 504
6x = 492
x = 492/6
x = 82 ft
So the other pieces are
(x + 6)/3 = 82+6/3 = 88/3 ft
And lastly
2 + 2x/3
= 2 + 164/3 ft

A(5, 8) and B(-1,-4)
Find the coordinates of the midpoint
Answer:
[tex]m = (2,6)[/tex]
Step-by-step explanation:
Given
A(5, 8) and B(-1,-4)
Required
Determine the midpoint
Represent the midpoint with m
m is calculated as thus:
[tex]m = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]
Where:
[tex](x_1,y_1) = (5,8)[/tex] ---- A
[tex](x_2,y_2) = (-1,4)[/tex] ------ B
So, the expression:
[tex]m = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]
becomes
[tex]m = (\frac{5 -1}{2},\frac{8 + 4}{2})[/tex]
[tex]m = (\frac{4}{2},\frac{12}{2})[/tex]
[tex]m = (2,6)[/tex]
Hence, the coordinates of the midpoint is: (2,6)
