Answer: 50 hours

Step-by-step explanation:

Given

The volume of a swimming pool is [tex]25,000[/tex] gallon

It takes 30 minutes to fill [tex]250\ \text{gallons}[/tex]

Using Unitary method

[tex]\Rightarrow 250\ \text{gallon takes}\rightarrow 30\ \text{minutes}\\\Rightarrow 1\ \text{gallon takes}\rightarrow \dfrac{30}{250}\\\\\Rightarrow 25,000\ \text{gallon}\rightarrow \dfrac{30}{250}\times 25,000=3000\ \text{minutes or 50 hours}[/tex]

Answer:

6/10 = 0.6

3/25 = 0.12

1/5 = 0.2

14/20 = 0.7

24/50 = 0.48

1/2 = 0.5

8/25 = 0.32

4/10 = 0.4

17/20 = 0.85

6 x 4/8 = 3

6 x 4/12 = 2

8 x 18/8 = 18

Answer:

See below.

Step-by-step explanation:

Let f = cost of one flower, and let b = cost of one bush.

First order:

24f + 6b = 144

Second order:

18f + 3b = 90

We have a system of two equations in two unknowns.

24f + 6b = 144

18f + 3b = 90

The first equation is divisible by 6, so let's divide both sides of the first equation by 6. The second equation is divisible by 3, so let's divide both sides of the second equation by 3.

4f + b = 24

6f + b = 30

To solve by substitution, we solve the first equation for b.

b = 24 - 4f

Now we substitute b in the second equation with 24 - 4f.

6f + 24 - 4f = 30

2f + 24 = 30

2f = 6

f = 3

Now we substitute 3 for f in the equation above that is solved for b.

b = 24 - 4(3)

b = 24 - 12

b = 12

f = 3 means the price of one flower is $3.

b = 12 means the price of one bush is $12.

Answer:

4 [tex]\frac{2}{4}[/tex]

Step-by-step explanation:

1+1=2 and 1[tex]\frac{1}{4}[/tex] + 1[tex]\frac{1}{4}[/tex]=2[tex]\frac{2}{4}[/tex]

2+2[tex]\frac{2}{4}[/tex]= 4[tex]\frac{2}{4}[/tex]

Answer:

4 1/2

Step-by-step explanation:

Once we add them up we get 4 2/4, simplified is 4 1/2.

Answer:

-5/13<x<0

Step-by-step explanation:

5/x+6<-7

subtract 6 from both sides

5/x+6-6<-7-6

5/x<-13

since it is just like a normal equation with an equals sign you can still switch the -13 and x to get

-5/13<x<0

Hope that helps :)

Answer:

11 for the son and 33 for his dad

Step-by-step explanation:

11+11=22

33+11=44

Answer:

1) 189.25 square inches

2) 21 square feet

Step-by-step explanation:

1) In order to find the area of a semicircle, you use  (πr^2)/2. When you plug in 3.14 as pi and 5 as your radius, you'll get 39.25. The area of the rectangle is base x height which is 10 x 15/150. 150 + 39.25 = 189.25

2) If you draw a vertical line that is parallel to the 2 feet measure, you'll have two rectangles with areas (5x3) and (3x2). 15 + 6 = 21

Step-by-step explanation:

(4 + 7 + 5 + 5 + 2) + (14 5/8 + 14 3/4 + 14 7/8 + 15 + 15 1/8)

23 + (14 5/8 + 14 3/4 + 14 7/8 + 15 + 15 1/8)

23 + 74 1/8

97 and 1/8

I took the test :)

Step-by-step explanation:

A pair of opposite rays are two rays that have the same endpoint and extend in opposite directions. Rays are always named with two points and the first point in the name must be the endpoint. So, when you name opposite rays, the first letter in the name of both rays must be the same.

Answer:

The speed of the plane is [tex]v=1.2\: m/s[/tex]

Step-by-step explanation:

The vector (5,6) represents a point in the coordinate system time-position.

So, we have that at t = 5 s the position is x = 6.

Let's recall that the slope of this vector is the speed, then using the tangent definition:

[tex]v=\frac{x}{t}=\frac{6}{5}[/tex]

[tex]v=1.2\: m/s[/tex]

I hope it helps you!

Answer:

$ 50

Step-by-step explanation:

sp = mp - discount percent of mp

or, 42 = mp - 16/100 * mp

or, 42 = 84 mp / 100

so, mp = 50

Answer:

100 - 84

50 - 42

original price=$50

The right answer is 8 hope I helped

4.82 × 10⁻⁴

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:

4.82 x 10^-4

Step-by-step explanation:

8.2 x 10^-4 + .0004= enter into calculator

.000482, move decimal behind first whole number and count places

it moves 4 spaces and because it starts in front of the number your exponent is negative
