You need to pump water out of a flooded basement, using two 50-gallon-per-minute (gpm) pumps. The basement has the dimensions shown and is flooded to a depth of 16 inches. How long will it take to pump the water out of the basement?

Answers

The two pumps working together would pump out water at a rate of 100 gallons per minute. To determine the time it takes to completely pump out the water from the basement, we need to determine the volume of the water in the basement. The dimensions of the basement is 40 feet by 50 feet (given elsewhere) while the depth of the water is said to be  16 inches. From these dimensions, we can calculate for the volume as follows:

V = length x width x depth
length = 50 feet
width = 40 feet
depth = 16 inches ( 1 foot / 12 inches ) = 1.33 feet

V = 50 x 40 x 1.33 = 2666.67 ft^3 = 19948.05 gal

Time = V / rate
Time = 19948.05 gal / 100 gal / min
Time = 199.48 min

In a rain forest, it typically rains 290 days out of the year. If it rains today, what is the probability that it will rain tomorrow?

a. 72%
b. 81%
c. 79%
d. 61%

Answers

Hey there!

Since we weren't given any probabilities based on the chance of rain after it rained the day before, we can assume the probability will stay the same. We can disregard "If it rains today...". 

If it rains 290 days out of the year (365 days), there will be a 290/365 chance of rain of a particular day. You can divide 290 by 365 to get a 79% chance. 

Hope this helped you out! :-)

Line A: 2x + 2y = 8 Line B: x + y = 4 Which statement is true about the solution to the set of equations? It is (8, 4). It is (4, 8). There is no solution. There are infinitely many solutions.

Answers

We want to check how many intersections line A and B have, that is, we want to check how many common solutions do these equations have:

i) 2x + 2y = 8

ii) x + y = 4

use equation ii) to write y in terms of x as : y=4-x, 

substitute y =4-x in equation i):

2x + 2y = 8
2x + 2(4-x) = 8
2x+8-2x=8
8=8

this is always true, which means the equations have infinitely many common solutions.


Answer: There are infinitely many solutions.

The cruise control feature on a car is set to maintain a speed of 65 miles per hour. The car’s actual speed never varies by more than three mph. Select the inequality that represents the speed of the car while cruise control is being used.


Answers

Final answer:

The inequality that represents the speed of the car while cruise control is being used is 62 ≤ s ≤ 68, where s is the car's speed and it shows the car's speed will be at least 62 mph and at most 68 mph.

Explanation:

The cruise control feature on a car is designed to maintain a steady speed, in this case, 65 miles per hour. However, it is acknowledged that the car's actual speed can fluctuate slightly. The question asks for an inequality that represents the potential speed of the car while cruise control is in use.

Considering the car's speed can vary by up to 3 mph more or less than the cruise control setting, we can set up an inequality to describe this range of speeds. The car's speed (s) should be no more than 3 mph above 65 mph and no less than 3 mph below 65 mph. Therefore, the inequality that represents the speed s of the car would be:

62 ≤ s ≤ 68

This inequality shows that the car's speed will be at least 62 mph and at most 68 mph, encompassing the 3 mph range of variation allowed by the cruise control setting.

If the area of a rectangle is 24a2b and the length is 8ab2, what would be the width of the rectangle, given that width is found by dividing area by length? Simplify the answer.

the quantity of 3 times a all over b
b over the quantity 3 times a
3 over the quantity a times b
3ab

Answers

Answer:

Option the quantity of [tex]3[/tex] times a all over b

Step-by-step explanation:

we know that

The area of rectangle is equal to

[tex]A=LW[/tex]

where

L is the length side of rectangle

W is the width side of rectangle

In this problem we have

[tex]A=24a^{2}b\ units^{2}[/tex]

[tex]L=8ab^{2}\ units[/tex]

Remember that

[tex]W=\frac{A}{L}[/tex]

substitute

[tex]W=\frac{24a^{2}b}{8ab^{2}}=\frac{3a}{b}\ units[/tex]

how do you solve f + 15 = 35

Answers

So what we do to one side of the equal sign, we must do to the other side as well.


We want to solve for f, so we need to subtract 15 on both sides of the equal sign in order to get f alone by itself on the left side:


[tex] f=20 [/tex]


So now we know that f = 20.

f + 15 = 35


Isolate the variable (f). Note the equal sign. What you do to one side, you do to the other.


Subtract 15 from both sides


f + 15 (-15) = 35 (-15)


f = 35 - 15


Simplify


f = 20


f = 20 is your answer


hope this helps

What is the simplified form of √10000x^64 ? 5000x^32 5000x^8 100x^8 100x^32

Answers

Answer:

Option (d) is correct.

[tex]\sqrt{10000x^{64}}=100x^{32}[/tex]

Step-by-step explanation:

Given : Expression [tex]\sqrt{10000x^{64}}[/tex]

We have to write a simplified form of the given expression [tex]\sqrt{10000x^{64}}[/tex]

Consider the given expression [tex]\sqrt{10000x^{64}}[/tex]

[tex]\mathrm{Apply\:radical\:rule\:}\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0[/tex]

[tex]=\sqrt{10000}\sqrt{x^{64}}[/tex]

Factor 10000 as [tex]10000=100^2[/tex]

[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a[/tex]

[tex]\sqrt{100^2}=100[/tex]

also, [tex]\mathrm{Apply\:radical\:rule\:}\sqrt[n]{a^m}=a^{\frac{m}{n}},\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]

We have,

[tex]\sqrt{x^{64}}=x^{\frac{64}{2}}=x^{32}[/tex]

Thus, [tex]\sqrt{10000x^{64}}=100x^{32}[/tex]

randy made a business trip of 204 miles. he averaged 52 mph for the first part of the trip and 50 mph for the second part. if the trip took 4 hours, how long did he travel at each rate?

Answers

x+y = 4

x=4-y

52x+50y=204

52(4-y)+50y=204

208-52y+50y=204

208-2y=204

-2y=-4

y=2

x= 4-2=2


check 52*2=104

50*2 = 100

104+100=204

 so he traveled 2 hours at both 50 and 52 mph

A girl wants to count the steps of a moving escalator which is going up. If she is going up on it, she counts 60 steps. If she is walking down, taking the same time per step, then she counts 90 steps. How many steps would she have to take in either direction, if the escalator were standing still?

Answers

Solve the how many steps will the girl direction, if the escalator were standing still.
So let,
V the speed of the girl per step
v the speed of the escalator per step
L the length between ground and floor in number of steps
V*60+v*60 = L => V+v=L/60
V*90-v*90 = L => V-v=L/90
By adding the equations V+v = L/60 and V-v=L/90 we get:
2V = L(3+2)/180
V = 5L/360
V = L/72
Time to climb (in steps) with v=0 (escalator standing still) is:
V*t = L
t = L/V
t = L/(L/72)
t = 72 steps
The girl will count 72 steps.

Finding the change in y/change in x=the slope, we get
(13-11)/(-4-(-2))=2/-2=-1. Therefore, the equation is y=-1*x+b. Plugging it into (-4, 13), we note that 13=4+b and b=9 by subtracting 4 from both sides, making the equation y=-x+9. Plugging it into A, we get that
1 (y , the second value) = -x+9. Subtracting both sides by 9, we get 1-9=-x and -8=-x. Multiplying each side by -1, we get x=8
