Answer:

B and C are the correct options

The side length of the square with an area of 24 square units will be √24 units. Then the correct options are B and C.

Every one of the sides of a square is consistent. Let 'x' be the side length of the square. Then the region of the square is the square of the side length of the square.

Then the area of the square will be

Area of the square = x² square units

The expression is given below.

⇒ √24

If the area of the square is 24 square units. Then the side length is given as,

x · x = Area

x · x = 24

x² = 24

x = √24

The side length of the square with an area of 24 square units will be √24 units. Then the correct options are B and C.

Answer:

A = $759.23 after 5 years

Step-by-step explanation:

The compound interest formula applicable here is

A = P(1 + r/n)^(nt), where n is the number of compounding periods per year.

Here P = $550, r = 0.065, n = 4 and t = 5.

We get A = $550(1 + 0.065/4)^(4*5), or

             A = $550(1 + 0.01625)^20, or:

              A = $759.23

Answer:

Here is the answer

Step-by-step explanation:

Answer:

$20070

Step-by-step explanation:

Given data

Time= 5 years

Principal= $15,000

Rate= 6%

Total amount=  P (1 + i)^t

substitute

Total amount=  15000(1 + 0.06)^5

Total amount=  15000 (1.06)^5

Total amount=  15000*1.338

Total amount=  $20070

Hence the total amount will be $20070

Answer:

  b(t) = 36000·e^(0.12t)

Step-by-step explanation:

Continuous growth at a rate of r per time period is modeled by the exponential multiplier e^(rt), where t is the number of time periods. This value multiplies the initial amount (at t=0). In this case, the model would be ...

  b(t) = 36000·e^(0.12t)

where b(t) is the number of bacteria in the colony after t time periods.

Answer:

B. -1

Step-by-step explanation:

-1

According to the slope formula:

Slope = (y2 - y1)/(x2 - x1)

y2 = 6.1

y1 = 3.1

x2 = -5.5

x1 = -2.5

Therefore:

6.1-3.1/-5.5--2.5

Since negative negative is positive you are left with:

3/-3

Therefore the answer is -1.

Answer:

3

Step-by-step explanation:

5 - 4x = -7

add 4x to each side of the equation:

5 = 4x - 7

add 7 to each side:

12 = 4x

divide both sides by 4:

x = 3

proof:

5 = 4(3) - 7

5 = 12 - 7

5 = 5

Hello There!

The area of a rectangle is equal to length times width

2*9=18 so the area of the rectangle is 18 square feet

If a triangle is formed in a rectangle then that triangle is 1 half of the area of the rectangle

18/2=9 so the area of the triangle is 9 square feet

Answer:

56.52m

Step-by-step explanation:

This is because pie is commonly substitued as 3.14 and since the formula of a cicumference is piRx2 it would be 56.52

The circumference of the circle is 18π meters.

A circle is a two-dimensional figure with a radius and circumference of 2πr.

The area of a circle is πr².

We have,

The circumference of a circle can be found using the formula:

C = 2πr

where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14159.

Substituting r = 9 m into the formula, we get:

C = 2π × 9

C = 18π m

Therefore,

The circumference of the circle is 18π meters.

Answer:

Since congruent means that they have the same diameter , i'd say that the answer is 1

Step-by-step explanation:

I can't see pictures, so I'll do my best.

y= always stays the same.

To find the slope, or x, you have to start at the y-intercept, and find the number of units up, then right.

For example, y=4/3+6

4/3 is the slope because it goes up 4 units and right 3 units from the y-intercept.

6 is the y-intercept, which is the y-coordinate. It can also be graphed as (0,6).

Answer:

v = 120

Step-by-step explanation:

If v is inversely proportional to square root of d, then we can write

[tex]v \sqrt{d}[/tex] = k    

If v  = 30 and d = 400, then

30([tex]\sqrt{400}[/tex]) = k

k = 30(20) = 600

Now [tex]v \sqrt{d}[/tex] = 600

If d = 25, then v[tex]\sqrt{25}[/tex] = 600

                         5v = 600

Step-by-step explanation:

One hour is 90 minutes 90/15=6 then you take 20X6=120miles

Answer:

It will travel 120 miles

Step-by-step explanation:

First, convert the hour and half to minutes: 90 minutes.

Then divide 90 with 15: 6

Then since there are 6 sections of 15 minutes, you would multiply 20 times 6 which is 120.

Angle 3: 130

Angle 5: 50

Angle 6:  130

Step-by-step explanation:

If angle 2 is 50, that means 4,5, and 7 are 50 as well

Also, if we know angle 2 is 50, we know 1,3,8, and 6 are 130 since a line is always 180 (so subtract 50)
