pi times 2.25 is 7.06

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:

if you are asking for the total of fiction books that were there then I think about 28 books were there.

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.

Answer:

The 10th term will be:

t₁₀ = 39366

Step-by-step explanation:

Given the sequence

tₙ = -3 tₙ₋₁

Given

t₁ = -2

substitute n = 2, to determine the 2nd term

tₙ = -3 tₙ₋₁

t₂ = -3 tₙ₋₁

t₂ = -3 t₂₋₁

t₂ = -3 t₁

t₂ = -3 × -2        ∵ t₁ = -2

t₂ = 6

substitute n = 3, to determine the 3rd term

tₙ = -3 tₙ₋₁

t₃ = -3 t₃₋₁

t₃ = -3 t₂

t₃ = -3 × 6        ∵ t₂ = 6

t₃ = -18

substitute n = 4, to determine the 4th term

tₙ = -3 tₙ₋₁

t₄ = -3 t₄₋₁

t₄ = -3 t₃

t₄ = -3 × -18       ∵ t₃ = -18

t₄ = 54

substitute n = 5, to determine the 5th term

tₙ = -3 tₙ₋₁

t₅ = -3 t₅₋₁

t₅ = -3 t₄

t₅ = -3 × 54      ∵ t₄ = 54

t₅ = -162

substitute n = 6, to determine the 6th term

tₙ = -3 tₙ₋₁

t₆ = -3 t₆₋₁

t₆ = -3 t₅

t₆ = -3 × -162      ∵ t₅ = -162

t₆ = 486

substitute n = 7, to determine the 7th term

tₙ = -3 tₙ₋₁

t₇ = -3 t₇₋₁

t₇ = -3 t₆  

t₇ = -3 × 486      ∵ t₆ = 486

t₇ = -1458

substitute n = 8, to determine the 8th term

tₙ = -3 tₙ₋₁

t₈ = -3 t₈₋₁

t₈ = -3 t₇  

t₈ = -3 ×  -1458      ∵ t₇ = -1458

t₈ = 4374

substitute n = 9, to determine the 9th term

tₙ = -3 tₙ₋₁

t₉ = -3 t₉₋₁

t₉ = -3 t₈  

t₉ = -3 ×  4374      ∵ t₈ = 4374

t₉ = -13122

substitute n = 10, to determine the 10th term

tₙ = -3 tₙ₋₁

t₁₀ = -3 t₁₀₋₁

t₁₀ = -3 t₉  

t₁₀ = -3 × -13122     ∵ t₉ = -13122

t₁₀ = 39366

Therefore, the 10th term will be:

t₁₀ = 39366

Step-by-step explanation:

9.94 => 10 (1s.f.)

29.7 => 30 (1s.f.)

Hence we estimate the value of 9.94² * 29.7

as 10² * 30 = 3,000.

Answer:

Well the estimate answer could be 293.54291

Step-by-step explanation:

But the real answer is 293.54292

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].

Step-by-step explanation:

first, we move the terms.

5u - 9u = 30 - 6

then, i collected the like terms and calculated them.

-4u = 24

then, i simply divided both sides.

u = -6

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

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.
