The length of a rectangle is 5 m less than six times its width. If the perimeter is 200 m, find the length and width of the rectangle.

Answers

Answer:

Let W be the width of the rectangle. The length will then be 6W (six times the width). The area is length times width. if this equals 216, then you have an equation

(6W)(W) = 216

6W2 = 216

W2 = 36

W = 6.

The width is 6 ft and the length must then be 6W = 36 ft.

To find the perimeter, use the formula

P = 2L + 2W.

Plug in:

P = 2(36) + 2(6) = 72 + 12 = 84 ft.

The perimeter is 84 ft. (Remember that area has units length units squared and perimeter has units same as length.)

Answer:

Negative

Step-by-step explanation:

From the number line we see that [tex]m[/tex] is negative and [tex]n[/tex] is positive

The expression in the parentheses, [tex](-m . n^2)[/tex] is positive since

[tex]-m[/tex] is the negative of a negative number and the sign of that is positive

[tex]n^2[/tex] is positive since a positive (or negative) number squared is always positive

[tex]\frac{m}{n}[/tex] is a negative number. If you divide a negative number, the sign of the result is negative

So evaluating the whole expression [tex]\frac{m}{n} .( m . n^2)[/tex]

gives us a negative number multiplied by a positive number and the result is a negative number

x=72, y=108

Step-by-step explanation:

y-36=x

[tex]\left \{ {{y-x=36} \atop {y+x=180}} \right.[/tex]

⇒ 2y=216

y=108

108-36=x

x=72
x+y=180--(1)x=y-36=>x-y=-36-(2)

Adding both

2x=144=>x=72

How many gallons of 35% alcohol solution and 50% alcohol solution must be mixed to get 9 gallons of 40%
alcohol solution?

There needs to be____
gallons of 35 % alcohol solution and____
gallons of 50 % solution.

Answers

Answer:

There needs to be   6     gallons of 35 % alcohol solution

and    3     gallons of 50 % solution.

======================================================

Explanation:

x = number of gallons of the 35% solution

y = number of gallons of the 50% solution

The two amounts must add to 9 gallons, so x+y = 9

This solves to y = 9-x

Since we want 9 gallons of 40% alcohol solution, this means we want 0.40*9 = 3.6 gallons of pure alcohol.

----------------

0.35x = amount of pure alcohol from the first batch

0.50y = amount of pure alcohol from the second batch

0.35x+0.50y = total amount of pure alcohol

Set that expression equal to the 3.6 figure calculated earlier (the total amount of pure alcohol we're after) and we get this equation

0.35x+0.50y = 3.6

----------------

Next, we replace y with 9-x and then solve for x.

0.35x+0.50y = 3.6

0.35x+0.50(9-x) = 3.6

0.35x+4.5-0.50x = 3.6

-0.15x+4.5 = 3.6

-0.15x = 3.6-4.5

-0.15x = -0.9

x = -0.9/(-0.15)

x = 6

We'll need 6 gallons of the 35% solution

Use this x value to find y

y = 9-x

y = 9-6

y = 3

We'll also need 3 gallons of the 50% solution

Step-by-step explanation:

Given Two Points are:

[tex] \sf \: \tt (6,-5) \: \sf and \: \tt (6,-4)[/tex]

We need to Find:

[tex] \longrightarrow \sf \: The \: Slope[/tex]

Solution:-

We know that,

[tex] \sf \: Slope = \tt \: Rise/Run \: , \: \sf \: i.e. \: \: \boxed{\tt\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

[tex] \sf \: Slope= \boxed{\tt\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

Where,

[tex] \tt \: y_2= -4[/tex]

[tex]\tt y_1= - 5[/tex]

[tex]\tt x_2=6[/tex]

[tex] \tt \: x_1=6[/tex]

So Substitute their values accordingly:

[Important Note: Slope is denoted as m generally.]

[tex] \tt\implies \: m = \cfrac{ - 4 -( - 5)}{6 - 6} [/tex]

Now Simplify it.[Follow BODMAS Rule strictly while simplifying]

[tex] \tt \implies m = \cfrac{ - 4 + 5}{0} [/tex]

[tex]\tt \implies m = \cfrac{ 1}{0} [/tex]

Here, We can find that 1 is divided by 0.

We know that any expressions divided by 0 is undefined .

Hence, the slope[m] would be undefined.

calculate the measure of each angle. find X

Answers

Solution:

Note that:

4x - 27 = 3x + 4 (Vertically opposite angles)

Using the equation (4x - 27 = 3x + 4), solve for x.

4x - 27 = 3x + 4=> -3x + 4x - 27 = 3x + 4 - 3x=> x - 27 = 4=> x - 27 + 27 = 4 + 27=> x = 31

The measure of x is 31.

Finding x

(4x-27)°=(3x+4)° [Vertically Opposite angles]

Solve for X ~

[tex] \bf4x - 27 = 3x + 4[/tex]

The time taken back to Boston will be t + 3

d1 = 60t
d2 = 60(t+3)
