Percentage increase = 20% × 400

New value =

400 + Percentage increase =

400 + (20% × 400) =

400 + 20% × 400 =

(1 + 20%) × 400 =

(100% + 20%) × 400 =

120% × 400 =

120 ÷ 100 × 400 =

120 × 400 ÷ 100 =

Answer:

(6x - 7) (6x - 7)

Step-by-step explanation:

A perfect square trinomial will be in the form of [tex]a^2[/tex] ± [tex]2ab + b^2.[/tex] A trick to factoring a perfect square trinomial would to write it as [tex](a^2[/tex]±[tex]b^2)[/tex]. (When doing this, the sign in the middle is determined by the middle sign in the original trinomial).

[tex]36x^2 -84x + 49[/tex] is known as a perfect square trinomial, too. Its first and last terms are both perfect squares (6x squared makes [tex]36x^2[/tex], 7 squared makes 49) and the middle term is 2 times the square roots of both of the other terms ( [tex](2) (7) (6x)[/tex] is [tex]84x[/tex]).

So, we can use the trick described earlier, and the answer would be [tex](6x-7)^2[/tex], also known as (6x-7) (6x-7).

Answer:

x=8

Step-by-step explanation:

Alright so those to angles are complemntary meaning that when they are added together it will equal 90. So first you wanna set up an equation which would be 90 = 40+6x+2. Then you combine like terms and end up with 90=42+6x. Next you wanna subtract each side by 42 and now you have 48=6x. finally you divide each side by 6 and get x = 8

Answer:

Exterior.

Step-by-step explanation:

A triangle has three sides. According to the theorem of exterior angles, the sum of two opposite interior angles is equal to the exterior angle of the triangle.

The sum of angle of triangle is equal to 180 degrees.

ATQ,

The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

Answer:

Lateral surface area = 106.4 [tex]in^{2}[/tex].

Step-by-step explanation:

Assumed that the oatmeal container has the shape of a cylinder. Its lateral surface area can be determined by:

lateral surface area = 2[tex]\pi[/tex]rh

But,

volume = [tex]\pi[/tex][tex]r^{2}[/tex]h

where: r is the radius, and h is the height.

From the question, volume = 239.4 [tex]in^{3}[/tex], and diameter = 9 inches, then;

radius = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{9}{2}[/tex]

          = 4.5

radius = 4.5 inches

Thus,

volume = [tex]\pi[/tex][tex]r^{2}[/tex]h

239.4 = [tex]\pi[/tex]x [tex](4.5)^{2}[/tex] x h

          = 20.25[tex]\pi[/tex]h

h = [tex]\frac{239.4}{20.25\pi }[/tex]

  = [tex]\frac{11.8222}{\pi }[/tex]

h = [tex]\frac{11.8222}{\pi }[/tex] inches

Therefore,

lateral surface area = 2[tex]\pi[/tex]rh

                                = 2[tex]\pi[/tex](4.5)([tex]\frac{11.8222}{\pi }[/tex])

                                = 2 x 4.5 x 11.8222

                                = 106.3998

Lateral surface area of the oatmeal container is 106.4 [tex]in^{2}[/tex].

Answer:

y = -1/4x+2

Step-by-step explanation:

The SIF (slope intercept form) is pretty easy once you get it down. the slope is the interger before x, and the y-intercept is b. so, if you input each number into it's spot, it would become y = -1/4x + 2.

Answer:

d represents distance

d = -16.8

Step-by-step explanation:

From the question, we are to find the vale of d from the expression

12+d = -4.8

Subtract 12 from both sides

12+d-12 = -4.8-12

d = -4.8-12

d = -16.8

Hence the value of d that makes two equation true is 16.8

d represents distance

d represents distance

d = -16.8

12+d = -4.8

12+d-12 = -4.8-12

d = -4.8-12

d = -16.8

Step-by-step explanation:

First, we need to find the unit rate to figure out how many miles Shane rides in 1 hour. To do this it is simple, I divided 12 and 2 to get 6 miles per hour. Then we would do 22/6 but we get a decimal so it would be about 3.66666666667.

Step-by-step explanation:

So we're trying to get from minutes to weeks.  The time intervals in question are:

Minutes -> Hours -> Days -> Weeks

So we set up our dimensional analysis.  We're solving for amount of problems, so that goes in the numerator of the first fraction:

[tex]\frac{1problem}{1.5min}[/tex]

Now we want to know how many minutes in an hour, so we multiply by the next fraction:

[tex]\frac{1problem}{1.5min} * \frac{60min}{1hr}[/tex]

After that, we want to know how many hours in a day:

[tex]\frac{1problem}{1.5min} * \frac{60min}{1hr} * \frac{24hr}{1d}[/tex]

and how many days in one week:

[tex]\frac{1problem}{1.5min} * \frac{60min}{1hr} * \frac{24hr}{1d} * \frac{7d}{1w}[/tex]

To solve the dimensional analysis problem, we multiply across the top of the entire expression, then divide across the bottom.  So:

1 * 60 * 24 * 7 = 10,080

And then divide that by the bottom:

10,080 / 1.5 / 1 / 1 / 1 = 6,720

So you can solve 6,720 problems in one week.  Multiply that by six and we get your answer:

40,320 dimensional analysis problems can be completed in 6 weeks of Chemistry class.
