it takes three identical water pumps 7 hours to fill a pool, how long would it take two of the same pumps to fill the pool, assuming they all pump at the same rate. please help
Answer:
10.5 hrStep-by-step explanation:
7 hr/3 pumps
So first we want to find the unit rate which would be...
5.25 hr/1 pump
Now that we found the unit rate we are going to multiply it by 2 because there are 2 pumps...
5.25*2=10.5
So our answer is 10.5 hr/ 2 pumps

Answer:
17 to 24
25 to 32
Step-by-step explanation:
8-1=7
16-9=7
therefore it means we add 7 on the next number which is 17; to get 24,and also to the next number after 24 which is 25 to get 32
Answer: 17 to 24 then 25 and 32

What is the smaller angle formed by the minute and hour hands at 3:30pm?
the angle would be a 90° angle
========================================================
Explanation:
At 3:00 pm, the hour hand is pointed directly at the '3'. At 4:00 pm, the hour hand moves to point directly at the '4'.
Since 3:30 pm is the halfway point of 3:00 pm and 4:00 pm, this must mean the hour hand is halfway between the '3' and '4'.
Each little tiny tickmark on the clock represents 1 minute. From the "3" to "4", we have 5 tickmarks, so half of that is 5/2 = 2.5
The hour hand is pointing to 2.5 minutes after the 15 minute mark, meaning the hour hand is pointing to the 15+2.5 = 17.5 minute mark.
The span of time from 17.5 minutes to 30 minutes is 30-17.5 = 12.5 minutes.
Divide this over 60 minutes and we get 12.5/60 = 125/600 = 5/24
The 5/24 indicates the fractional amount of 360 degrees being taken up by this angle shown.
So, (5/24)*360 = 75 degrees is the angle measure in this diagram.

1. Find the general formula that gives the nth term for each of the sequences below
(remember this is NOT the recursive rule).
(a) Odd numbers:
(b) Triangular numbers:
(c) Square numbers:
9514 1404 393
Answer:
(a) an = 2n -1
(b) an = n(n +1)/2
(c) an = n^2
Step-by-step explanation:
(a) The odd numbers are an arithmetic sequence with first term 1 and common difference 2. The general term is ...
an = a1 +d(n -1)
an = 1 + 2(n -1)
an = 2n -1
__
(b) The triangular numbers are a quadratic sequence with first term 1, first first difference 2, and second differences 1.
The first few terms and differences are ...
sequence: 1, 3, 6, 10, 15, 21, 28, ... (a1 = 1)
first diff: . . . 2, 3, 4, 5, 6, 7, ... (d1 = 2)
2nd diff: . . . . 1, 1, 1, 1, 1, ... (d2 = 1)
There is a sort of general formula* that can make use of these numbers to give the general term of the sequence:
an = a1 +(n -1)(d1 +(n -2)/2(d2))
For the values we have, this gives our general term as ...
an = 1 + (n -1)(2 +(n -2)/2(1))
an = n(n +1)/2
__
(c) The general term in the sequence of square numbers is simply the square of the term number:
an = n²
_____
* There are a number of other ways to get to the general formula for triangle numbers. You can search for it, since it is well-known. You can use a quadratic regression tool on the sequence of numbers. You can develop a system of equations to find the coefficients of the quadratic equation.
The general formula given can be used to find polynomial sequences of any degree. Coefficients at successive layers in the formula are of the form (n -k)/k. The first term in parentheses following that is the first k-th difference.
4.Solve: (x – 3)(x – 5) = 35 (hint: first you must distribute; then set your equation equal to zero, then factor, then solve.

Rotate shape A 180 about point (1,0)
The point after which shape A is rotated 180 degrees is (-1, 0).
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
Shape A is in the point (1, 0).
This means,
Shape A is in the First Quadrant.
Now,
Shape A is rotated 180 degrees.
If rotated clockwise or counterclockwise shape A will be in the same quadrant.
This means,
Shape A will be in the Third quadrant.
Now,
First quadrant coordinates = (x, y)
Third quadrant coordinates = (-x, -y)
So,
(x, y) → (-x, -y)
(1, 0) → (-1, 0)
Thus,
Shape A will be in (-2, 0).

Suppose Clara has a collection of old CDs. If the diameter of a CD measures about 12 centimeters, approximate the circumference of the CD. Round your answer to the nearest tenth of a centimeter.
Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm

Hint There is more than one answer to this problem)
Answer: He can buy 12 shooters with $1. 20 red marbles with $1. 300 multicolored marbles.
Step-by-step explanation:
Shooters = 1 dollar is 60 cents
60 divided by 5 = 12
Red = 60 divided by 3
= 20
Multicolored = 60 x 5 because 1 for 5
= 300
