Can somebody answer this please :) ?

Answer: 17/60

Step-by-step explanation:

Suppose that whe have N fishes.

We know that 1/5 of these N fishes are guppies.

We also know that 1/12 of these N fishes are goldfish.

Now, what is the fraction of guppies and goldfish together?

We only need to add the fractions:

1/5 + 1/12

This may be hard because the denominators are different, then the first step will be to write both fractions with the same denominator.

We know that:

5*12 = 60

Then we can write:

1/5 = (12/12)*(1/5) = 12/(5*12) = 12/60

and

1/12 = (5/5)*(1/12) = 5/(5*12) = 5/60

Then our previous sum:

1/5 + 1/12

can be written as:

12/60 + 5/60

and this is easy to solve:

12/60 + 5/60 = (12 + 5)/60 = 17/60

This is the fraction of the fish that are guppies or goldfish.

Answer:

x = - 4

Step-by-step explanation:

First do distributive property

5x-15=10x+5

then add 15

5x=10x+20

-10x

-5x=20

divide 5

x=-4

Answer:

x = -4

Step-by-step explanation:

5(x−3) = 10x+5

5x−15 = 10x+5 (Simply both sides of the equation)

−5x−15 = 5 (Subtract 10x from both sides)

−5x = 20 (Add 15 to both sides)

−5x /−5  =  20 /−5  (Divide both sides by -5.)

x = -4

Velocity of light is ~3 x 10^5 km/sec. Time taken for light to reach the earth is ~ (1.496 x 10^8)/(3 x 10^5)sec = 1496/3 sec = 498.3sec = 8min 18.3 sec. 1.496X10*8 * .00257 = 384,472 km. Circumference of Earth = 6.28*6378=40,054 km. 384472/40054=9.6 = trips around earth's equator. 1.496 * 108 kilometers = 161,568 meters. D. 0.00000001496

Step-by-step explanation:

Required information The Foundational 15 [LO8-2, LO8-3, LO8-4, LO8-5, LO8-7, LO8-9, LO8-10]

The expression of the Earth 1.496 x 10^8 km  in standard form is 149,600,000

Standard form is a simple way of expressing very large numbers into small sizes for easier calculation.

The given information is already in its standard form as 1.496 × 10⁸ km.

We can express it in its ordinary form by shifting the decimal place to the right side in terms of the power with which it is being raised.

Here:

1.496 × 10⁸ km = 149,600,000 km

Answer:

Area of the square is 2916 [tex]m^{2}[/tex].

Step-by-step explanation:

Let the breadth of the rectangle be represented by w. So that;

length of rectangle = 5w

Area of rectangle = length x breadth

                             = 5w x w

1620 = 5[tex]w^{2}[/tex]

divide through by 5 to have,

[tex]w^{2}[/tex] = 324

w = [tex]\sqrt{324}[/tex]

   = 18

Thus, the breadth of the rectangle is 18 m.

length = 5 w = 5 x 18

           = 90 m

The length of the rectangle is 90 m.

Perimeter of the rectangle = 2(l + w)

                                  = 2( 90 + 18)

                                  = 216 m

Perimeter of a square = 4l

where l is the length of its side.

Given that the perimeters of the rectangle and square are equal, then;

4l = 216

l = [tex]\frac{216}{4}[/tex]

 = 54

length of the side of square is 54 m.

Therefore,

Area of square = [tex]l^{2}[/tex]

                         = [tex]54^{2}[/tex]

                        = 2916

Area of the square whose perimeter is equal to that of the rectangle is 2916 [tex]m^{2}[/tex].

Step-by-step explanation:

Answer:

In this equation, let "x" equal the rate at which the tub will be filled. The tub holds 32 gallons, which will be one half of the equation. The tub already contains 12 gallons, so this will be half of the other side of the equation. The rate is "x" gallons per minute, and the time it required was 5 minutes, so this would be "5x". Placing all these parts together gives an equation of (32 = 5x + 12) gallons per minute dispensed.

Hey there! :)

3t - 18 = 4(-3 - 43t)

Let's start on the right side of the equal sign by multiplying "4" with everything inside of the parenthesis. Keep in mind that a negative times a negative is a positive & a negative times a positive is a negative.

Let's put this all together:

3t - 18 = -12 - 172t

Now, we need to isolate "t." We can do this by adding 18 to both sides along with adding "172t" to both sides.

3t - 18 + 18 + 172t = -12 - 172t + 172t + 18

Simplify.

3t + 172t = -12 + 18

Simplify - add like terms!

Let's put this all together:

175t = 6

Divide both sides by 175.

175t ÷ 175 = 6 ÷ 175

Simplify.

Answer:

2, 4 6 and 8

Step-by-step explanation:

Given the range of a function expressed as ƒ(x) = -6x + 11 where x are the values of the domain

Given the follwing range f(x) =  {–37, –25, –13, –1}, we are to find the corresponding value of x;

-37 = -6x + 11

-37 - 11 = -6x

-48 = -6x

x = -48/-6

x = 8

if f(x) = -25

-25 = -6x + 11

-6x = -25-11

-6x = -36

x = -36/-6

x = 6

if f(x) = -13

-13 = -6x + 11

-6x = -13-11

-6x = -24

x = -24/-6

x = 4

if f(x) = -1

-1 = -6x + 11

-6x = -1-11

-6x = -12

x = -12/-6

x = 2

Hence required domain values are 2, 4 6 and 8
