D.

Answer:

8ft x 6ft

Step-by-step explanation:

For this problem, we want to create measurements of length and width that double our current area.  First we need to find the current area.

C_Length = 6 ft

C_Width = 4 ft

C_Area = C_Length * C_Width

C_Area = 6 ft * 4 ft = 24 ft^2

Now we want our new area to be double the old area.

N_Area = 2C_Area

N_Area = 2 * 24 ft^2

N_Area = 48 ft^2

Now we simply need to find the increase in width and length, distributed equally, that will create the new area.

N_Area = (C_Length + x) * (C_Width + x)

Where x is the amount that each variable is increased by to create the new area.

Now we simply solve for x.

N_Area = (C_Length + x) * (C_Width + x)

48 = (6 + x) * (4 + x)

48 = 24 + 10x + x^2

0 = -24 + 10x + x^2

Now we can either apply the quadratic formula or attempt to factor using the constant break down method.

(x + 12) (x - 2) = 0

x = -12; x = 2

Note that we will choose x = 2 since the other option would require us to have negative material, which is impossible.

Now we can check to validate our answer by plugging in the value of x.

48 ?= (6 + 2) * (4 + 2)

48 ?= (8) * (6)

48 == 48

Thus, we have found the dimensions of the new aquarium, 8ft x 6ft.

Answer:

A) 4 Hours (of running)

B) 5 Hours (of biking)

Step-by-step explanation:

So Suzette ran and biked for a total of 80 miles,

and she did all of that in 9 hours.

Let x equal the total hours of Suzette ran and let y equal the total hours of Suzette biked.

Therefore:

[tex]x+y=9[/tex]

This represents the total hours. We know that the hours she had ran and biked totals 9. Thus, x plus y must equal 9.

And also:

[tex]5x+12y=80[/tex]

The 5x represents the miles she had ran in x hours, while the 12x represents the miles she had biked in y hours. All together, they must equal 80 miles total.

Therefore, our system is:

[tex]x+y=9\\5x+12y=9[/tex]

We can solve this using substitution. First, subtract x from the top equation:

[tex]x+y=9\\y=9-x[/tex]

Now, substitute the y into the second equation:

[tex]5x+12y=80\\5x+12(9-x)=80[/tex]

Distribute:

[tex]5x+108-12x=80[/tex]

Combine like terms:

[tex]-7x+108=80[/tex]

Subtract 108 from both sides:

[tex](-7x+108)-108=(80)-108\\-7x=-28[/tex]

Divide both sides by -4:

[tex]x=4[/tex]

Therefore, Suzette ran for a total of 4 hours.

Since she biked and ran for a total of 9 hours, she must have biked for 9-4 or 5 hours.

Checking:

4 hours of running plus 5 hours of biking does indeed equal 9 hours total:

[tex]4(5)+5(12)=20+60=80[/tex]

So by running 5mph for 4 hours and by biking 12mph for 5 hours, she did indeed reach a total of 80 miles.

Answer:

0.0009

Step-by-step explanation:

9*10⁻⁴ = 0.0009

Answer: x = 21

Step-by-step explanation: First, isolate the x term by

subtracting 5 from both sides of the equation.

We get 1/3x = 7.

Next, multiply both sides of the equation by

the reciprocal of 1/3 which is 3/1 to get x by itself.

On the left, 3/1(1/3) cancels and on the

right when we multiply 7(3/1), we get 21.

So we have x = 21.

Answer:

[tex]\bold{x = \dfrac{8}{9}}[/tex]

Step-by-step explanation:

We have to rewrite the below as simplified fraction.

[tex]\large{0.\overline{8} = {?}}[/tex]

Solution:

Let [tex]x =0.\overline 8[/tex] which means [tex]x =0.888888.......[/tex]

Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.

To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.

So, we can rewrite [tex]x[/tex] as:

[tex]x =0.8\overline8[/tex] ......(1)

Now, let us multiply the above with 10.

[tex]10x = 0.8\overline 8 \times 10\\\Rightarrow 10 x= 8.\overline8[/tex] ....... (2)

Now, let us subtract (1) from (2):

[tex]10x-x=8.\overline8 - 0.\overline8\\\Rightarrow 9x = 8\\\Rightarrow \bold{x = \dfrac{8}{9}}[/tex]

So, in simplified fractions:

[tex]\large{0.\overline{8} = \bold{\dfrac{8}{9}}}[/tex]

Answer:

[tex]\bold{x = 34^\circ}[/tex]

Step-by-step explanation:

Given:

[tex]cos x = sin (x + 22^\circ)[/tex]

To solve:

The given equation.

Solution:

First of all, let us consider an important property of sine and cosine.

[tex]sin(90^\circ-\theta )=cos\theta[/tex]

OR

[tex]cos(90^\circ-\theta )=sin\theta[/tex]

We can apply above property to solve for [tex]x[/tex] as per given equation.

[tex]cos x = sin (x + 22^\circ)[/tex]

Changing [tex]cosx[/tex] to sine form:

[tex]cosx=sin(90^\circ-x)[/tex]

[tex]cosx=sin(90^\circ-x) = sin(x+22^\circ)[/tex]

[tex]\therefore 90^\circ-x=x+22^\circ\\\Rightarrow 90^\circ-22^\circ=x+x\\\Rightarrow 2x=68^\circ\\\Rightarrow \bold{x = 34^\circ}[/tex]

How long does it take a car to travel 1 mile if its average speed is 40 mph? The answer is 1/40 of an hour or 1.5 minutes. multiply this by 5

Answer:

0.1 hours to the nearest tenth (0.125 hours exact)

Step-by-step explanation:

For this problem, we simply need to do a conversion to find the length of time.

We are given the rate 40 miles per hour, and the distance of 5 miles.  We simply need to know the amount of time.

5 miles * (1 hour per 40 miles) =  1 hour / 8

Note, the distance unit cancels out.

So, to travel 5 miles it will take 1/8 of an hour.

1/8 as a decimal is equal to 0.125.  The answer rounded to the nearest tenth would be 0.1 hours, since the 2 rounds down.

40 field goals

Step-by-step explanation:

Represent 2-point with x and 3-point with y;

Given

[tex]x = 3y[/tex]

[tex]2x + 3y =90[/tex]

Required

Determine x and y

[tex]x = 3y[/tex]

[tex]2x + 3y =90[/tex]

Substitute 3y for x in [tex]2x + 3y =90[/tex]

[tex]2(3y) + 3y = 90[/tex]

[tex]6y + 3y = 90[/tex]

[tex]9y = 90[/tex]

Divide both sides by 9

[tex]y = 10[/tex]

Substitute 10 for y in [tex]x = 3y[/tex]

[tex]x = 3 * 10[/tex]

[tex]x =30[/tex]

The number of field goals = x + y

[tex]x + y = 30 + 10[/tex]

[tex]x + y = 40[/tex]

Hence, the number of field goals is 40
