The area of a rectangle is length*width.

The length of this 3x and the width is 2x-3. This means that, to find the area, you need to multiply 3x and 2x-3.

Start by writing out this equation:
A=l*w

Then, plug in your given values:
A= 3x*2x-3 (you can also write it as A= 3*x*2*x-3)

Then, following the order of operations, you start by multiplying. This makes your equation become A = 6x^2 -3. (^2 means squared). It turns into this because 3 * 2 is 6 and x * x is x^2 and you still haven’t used the 3 yet.

After this, there is nothing more that you can do to simplify the equation. Therefore, the area is 6x^2 - 3.

Kallisto built a rectangular sign that measured 2 and 3/4. The width is 1 and 1/4 shorter than the length. To find the area, multiply the length and width. What is the area in square feet write an equation to solve it

Answers

Answer:

l = 1 5/16

w = 1/16

A = 21/16 x 1/16 = 21/256

Step-by-step explanation:

Perimeter = 11/4

l = length

w = l - 5/4

2l + 2(l - 5/4) = 11/4

2l + 2l - -5/2 = 1/4

multiply each side by 4

8l + 8l - 10 = 11

16l = 21

l = 21/16 or 1 5/16

width = 21/16 - 20/16 = 1/16

There is a population of 10,000 bacteria in a colony. If the number of bacteria doubles every 14 hours, what will the population be 28 hours from now?

Answers

Answer:

for the first 14 hours it doubles to 20,000, then once it reaches 28 hours it'll be 40,000. its an exponential growth

What is an arithmetic operation?

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the set of information in the question,

Total population of Bacteria = 10,000

Rate of growth of bacteria = Twice in 14 hours

Rate of growth in 28 hours = 4 times the total population.

Then the total bacteria (B) in the colony after 28 hours,

B = 4 × 10,000

B = 40,000

What the volume of a cylinder with a diameter of 6mm and a height of 7 mm.it says it’s 700 something but the only answers on the test are as low as 100 and highest is 230? Help plz

8th grade math*

Answers

Answer: 197.82mm³

Step-by-step explanation:

Volume of a cylinder = πr²h

where,

π = 3.14

r = Diameter/2 = 6mm/2 = 3mm

h = 7mm

Volume = πr²h

= 3.14 × 3² × 7

= 3.14 × 9 × 7

= 197.82mm³

The volume of the cylinder is 197.82mm³

Sally found 33 fossils. She found twice as many plant fossils as animal fossils. How many of each type of fossil did she find

Answers

Answer:

a = 11

b = 33

Step-by-step explanation:

Given :

Total fossil found = 33

Let :

Number of plant fossil = b

Number of animal fossil = a

a + b = 33

Plant fossil = 2 times number of animal fossil

b = 2a

Put b = 2a

a + 2a = 33

3a = 33

Divide both sides by 3

3a/ 3 = 33/3

a = 11

a + b = 33

11 + b = 33

b = 33 - 11

b = 22

A cylinder has a diameter of 14 cm and a volume of 112 pi.

What is the height in, centimeters, of the cylinder?



(PS I am literally giving 15 points for the correct answer!!!)

HELP! :(

Answers

Height of cylinder is 2.285 centimeters

Diameter = 14 cm
Radius = 7 cm (14/2)
Volume = 112 pi

Volume of cylinder = pi(radius)^2 h
112pi = pi(7)^2 h
Divide both sides
112 = 49 h
h = 112/49
h = 2.285 centimeters

Pete bought a house in 2009 for $200,000.
The value of his house increased by 10%
annually.

Answers

Answer:

Value of house in 2021 = $627,680 (Approx.)

Step-by-step explanation:

Given:

Value of house in 2009 = $200,000

Rate increased per year = 10% annually

Find;

Value of house in 2021

Computation:

Number of year = 2021-2009 = 12 year

Value of house in 2021 = Value of house in 2009[1+Rate increased per year]ⁿ

Value of house in 2021 = 200,000[1+10%]¹²

Value of house in 2021 = 200,000[1+0.1]¹²

Value of house in 2021 = 200,000[1.1]¹²

Value of house in 2021 = 200,000[3.1384]

Value of house in 2021 = $627,680 (Approx.)

A satellite is 24,400 miles from the horizon of Earth. Earth’s radius is about 4,000 miles. Find the approximate distance the satellite is from the point directly below it on Earth’s surface. The diagram is not to scale.

Answers

Answer: There are several information's already given in the question. It will be easier to get the answer, if we write all the details down first.

AB = 13200 miles

AO = 4000 miles

OB = 4000 miles

Let us assume CB = x

Then

(x + 4000)^2 = (13200)^2 + (4000)^2

x = sqrt(13200^2 + 4000^2) - 4000

= 13793 - 4000

= 9793 miles.

From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option.

Answers

Step-by-step explanation:

tell me the answer when u get too!!

btw its 557/1980

The proof is shown in the solution.

What are recurring decimals?

A repeating decimal or recurring decimal is a decimal representation of a number whose digits are periodic, and the infinitely repeated portion is not zero.

Given that, show that the recurring decimal 0.2813 = 557 / 198

Let 0.2813 be x

0.2813 = x......(i)

2813.2813 = 10000x......(ii)

Subtracting eq(i) from eq(ii)

2813 = 999x

x = 2813 / 999

x = 557 / 198

Hence, proved
