Answers

Answer:

(2x+3)(x+6) or 2x^2 + 15x + 18

Step-by-step explanation:

Area = Length x Width

Length = (2x-3)

Width = (x+6)

(2x-3)(x+6)

2x^2 + 12x - 3x - 18

2x^2 + 15x + 18

Step-by-step explanation:

Plug 27 into the equation

a27=-10+(27-1)(-2)

27-1=26

26 times -2 = -52

-52-10=-62

a_n=-10-2(n-1)

Why do we do sampling?

We do sampling so that we don't have to work on entire population of items but only on that sample in a way that we can predict information about population.

Most of the times, it isn't possible in real world to work on entire populations. Samples come out for rescue by assumptions that they will have some properties of the population pertained in them.

Thus, the sample should be taken out such that it includes data of the population as much  as it can in unbiased way so as to imitate population.

Poll oftenly uses sampling.

The data obtained from the poll shows that:

20% of the students prefer the aquarium and 50% of the teachers the

aquarium.

That means, from the poll, we found that out of total students, 20% prefer aquarium whereas 50% of total teacher prefer aquarium.

Since we conclude from sampling only as this is the usual way we do conclusion about population, and since percentage shows that less students' proportion prefer aquarium than the proportion of teachers prefering aquarium, thus,

There is evidence that teachers at Woodlands Middle may prefer the aquarium (Option A) is the true statement from all the available options.

Jack borrowed $ 4,000.00 and paid $ 585.00
in simple interest after 4 year 6 months. What
was the annual rate of interest?​

Answers

Answer:

3.25%

Step-by-step explanation:

The formula for simple interest is I = PRT, where I = interest earned/paid, P = principal amount deposited or borrowed, R = rate of interest as a decimal, and T = time in years.

I = PRT

585 = (4000)(r)(4.5)

585 = 18,000r

r = 0.0325

Multiply by 100 to get the percentage

0.0325 = 3.25%

351.9 m²

Step-by-step explanation:

[tex]SA=2\pi r^2+2\pi rh[/tex] where r is the radius of the base and h is the height of the cylinder

We're given the diameter of the base, which is 8 m. Therefore, the radius is 4 m (after dividing by 2).

Plug in 4 as r and 10 as h

[tex]SA=2\pi (4)^2+2\pi (4)(10)\\SA=2\pi (16)+2\pi (40)\\SA=32\pi +80\pi \\SA=112\pi[/tex]

Therefore, the surface area of the cylinder is approximately 351.9 m² after rounding to the nearest tenth.

Answer:

∠BCA = 59

x = 2

∠B = 83

Step-by-step explanation:

Properties of a parallelogram:

Opposite angles are congruent

Opposite side lengths are congruent

That being said lets find x, ∠B and ∠BCA

First x

Segment AD and segment CD are parallels which are congruent

Knowing that we create an equation

6x = 12

step 1: Divide each side by 6

6x/6=x

12/6=2

we're left with x = 2

For ∠B

∠D and ∠B are opposite angles of a parallelogram

meaning that ∠D≅∠B

So if ∠D=83 then ∠B also = 83

For ∠BCA

∠BCA and ∠DAC happen to be opposite angles ( like stated previously opposite angles are congruent.)

Because ∠DAC = 59 ∠BCA also = 59

The perimeter of a rectangle is 62.the length is 5 less than 3times the width. Find the width and the length

Answers

Answer:

length = 22, width = 9

step by step explanation :

perimeter = 62

length = 3×width -5

∴ 2 ( length + width ) = perimeter

2 ( 3w-5 + w ) = 62

3w -5 + w = 62/2 = 31

3w -5 + w = 31

4w  = 31 + 5 = 36

4w = 36

 w =36/4

 w = 9

l= 3w-5 = (3×9)-5 = 27-5= 22

verifying -

2( l + b) = perimeter

2 ( 22 + 9 ) = 2 * 31 = 62

For example, you can use the points

(0, 8500) and (1700, 0)

slope = (difference in y)/(difference in x)

slope = (0 - 8500)/(1700 - 0) = -8500/1700 = -5

The slope is negative because the plane was losing altitude as it descended.

It descended at a rate of 5 meters per second.

Answer: B 5 meters per second
