Answer:

17/4 or 4 1/4

Step-by-step explanation:

Substitute x = 2 into the expression x² + 1/x².

Evaluate the exponents in the expression.

Multiply 4 by 4/4 to get a common denominator of 4.

Add the numerators together.

The value of x² + 1/x² if x = 2 is 17/4, or 4 1/4.

It is because u can only do pathagreom therom on right triangles.

2*2 + 2.1*2.1

4+4.41=8.41

square root of 8.41 is 2.9 so that confrms the therom which isaversa confirms it is a right triangle.

Step-by-step explanation:

If 18/22 is expressed in simplest terms. that is if both the numerator and denominator is divided by 2. It gives 9/11

We can determine if they are the same by multiplying both fractions by 100

9/11 x 100 = 81.8

18/22 x 100 = 81,8

they yield the same number, thus the records are the same

The description of Margot as a frail girl who had lost her vibrancy shows that she was in eager anticipation of the rain.

Step-by-step explanation:

The short story, "All Summer in a Day", tells of how a girl named Margot always stood differently from her classmates because she eagerly anticipated a time when the sun will come out as the scientists projected. It had been raining in this planet, Venus for seven years non-stop.

Margot who came from planet earth some five years ago could still clearly recall how the sun looked like and despite her description of it, the children still doubted her. On the day the sun finally came, the children locked Margot in a closet and she was unable to see the sun.

Answer:

D. 4.5%

Step-by-step explanation:

Michael expects the rate of growth to be 4.5% each week  because in the equation inside the parenthesis is 1.045 meaning it has already had 1 added to the original percentage so subtract 1 from 1.045 then move the decimal twice to the right and change it into a percentage sight which will give you 4.5%

the growth rate per week is 4.5% Micheal can expect.

Rate is a measurement to determine the change in one quantity with respect to another quantity.

The given equation is,

y = 82(1.045)x,

Where y represents number of people and x represent number of week.

After 1 week, x=1

y=82×1.045

The multiplying factor is 1.045

It implies that after 1 week growth increase by, 0.045

The percentage value of 0.045 is 4.5%

So the growth rate per week is 4.5%.

Answer:

30 is 120% of 25

Step-by-step explanation:

30 = 120% of y

[tex]\frac{120}{100}[/tex] × y = 30

After multiplying both sides by 100 and dividing both sides by 120, we have

y = 30 × [tex]\frac{100}{120}[/tex]

y = 25

Given:

Short sides of a rectangle = 2 inches.

Area of the rectangle = 22 square inches.

The long sides of the same rectangle are three less than an unknown number of inches.

To find:

The unknown number.

Solution:

Let x be the unknown number. Then the longer side of the rectangle is (x-3) inches.

We know that the area of a rectangle is

[tex]A=length\times width[/tex]

The area of the rectangle is 22 square inches.

[tex]22=2(x-3)[/tex]

Divide both sides by 2.

[tex]11=x-3[/tex]

Add 3 on both sides.

[tex]11+3=x-3+3[/tex]

[tex]14=x[/tex]

Therefore, the value of the unknown number is 14.

Answer:

12285

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

Step 1:

Subtract 1 from both sides

2x + 1 = 7

2x + 1 - 1 = 7 - 1

2x = 6

(1 - 1 will cancel itself out on the side with the variable.)

Step 2:

Divide both sides by 2

2x = 6

2x ÷ 2 = 6 ÷ 2

x = 6 ÷ 2

(2 divide by 2, will cancel itself out on the side with the variable.)

Step 3:

Solve for x

6 ÷ 2 = 3

x = 6 ÷ 2 = 3

x = 3

Answer:

5026.55in²

Step-by-step explanation:

Area = πr^2

radius (r) is half of the diameter, hence the radius is 40 inches

So after plugging that in, the equation should look like

Area = π(40)^2

A = 1600π ≈ 5026.55

The units for this is in² so just add that in the end
