Answer:

24 cm

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = [tex]\frac{s^2\sqrt{3} }{4}[/tex] ( s is the side length )

Here A = 16[tex]\sqrt{3}[/tex] , then equating gives

[tex]\frac{s^2\sqrt{3} }{4}[/tex] = 16[tex]\sqrt{3}[/tex] ( multiply both sides by 4 to clear the fraction )

s²[tex]\sqrt{3}[/tex] = 64[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

s² = 64 ( take square root of both sides )

s = [tex]\sqrt{64}[/tex] = 8

Thus

perimeter = 3 × 8 = 24 cm

A and B are alternate interior angles[tex].[/tex]

∴ ∠A = ∠B

➠ (2x - 20)° = 90°

➠ 2x = 90° + 20°

➠ 2x = 110°

➠ x = 110°/2

➠ x = 55°

The value of x for which d || m is 35° and their alternate angles are of equal measure.

A transversal is a line that intersects two lines on the same plane at two different points. When those two intersected lines are parallel their alternate angles, interior angles and exterior angles are equal and the converse of this statement is also true.

We know when two parallel lines are intersected by a transversal their interior alternate angles are equal.

∴ (2x - 20)° = 90°

2x = (90 - 20)°.

2x = 70°.

x = 35°.

Answer:

y = -3/4x + 7

Step-by-step explanation:

Given: m = -3/4

y = mx + b

(1) = -3/4(8) + b

1 = -6 + b

b = 7

Use m and b to form equation of line:

y = mx + b

y = -3/4x + 7

Answer: y = 7 over 10 x -8

Step-by-step explanation:The point we are given  (0,−8) is the y-intercept (c). The clue for this is that the x-value is 0, which means the point lies on the y-axis.

Answer:

Answer:

A. 27x<=150

B. x <=5 5/9

C. 5

Step-by-step explanation:

A. The amount of the boxes in inches has to be less than or equal to the storage unit in inches.

B. X is less than or equal to 27 divided by 150, which is 5 5/9.

C. Since you cannot have 5/9 of a box, you must round down and say that you can only stack 5 boxes vertically.

Answer:

Answer:

2240

Step-by-step explanation:

braniest pls

there are 2,240 women at the college.

To find the number of women at the college, we can use the ratio of men to women given and the known number of men.

The ratio of men to women is 5 to 4, which can be expressed as 5/4.

If we know that there are 2,800 men, we can set up a proportion:

5/4 = 2,800/x

To solve for x, the number of women, we cross-multiply:

5x = 4 * 2,800

5x = 11,200

Dividing both sides by 5:

x = 11,200 / 5

x = 2,240

Therefore, there are 2,240 women at the college.

Simple Interest

Simple interest represents a fee you pay on a loan or income you earn on deposits.

When borrowing money: You must repay the amount you borrowed and make extra payments for interest, which represents the cost of borrowing.

When lending money: You typically set a rate and earn interest income in exchange for making your money available to other people.

When depositing money: Interest-bearing accounts such as savings accounts pay interest income because you are making money available to the bank to lend to others.

How to Calculate It

In the following example, the term "simple" means you're working with the simplest way of calculating interest. Once you understand how to calculate simple interest, you can move on to other calculations, such as annual percentage yield (APY), annual percentage rate (APR), and compound interest.

Answer:

36 years

Step-by-step explanation:

Maria interest rates was to get 2% annual. Her interest rate do not change of 72. So you will have to divide 72 out of 2 which that will give you 36 . 36 years is your answer.

Maria's money would double in 36 years

The rule of 72 is an heuristic that is used to determine in how many years it would take an investment to double given the interest rate

Rule of 72 = 72 / interest rate

72 / 2% = 36 years

Assume Maria has $10,000 in her account, it would take 36 years for the money to double.

Step-by-step explanation:

-3(-5x+7)

you sidtribute the 3 to both numbers by multiplying both the -5 and the 7 by -3

-3 x -5x = 15x (remember, a negative times a negative equals a positive)

-3 x 7 = -21 (A negative times a positive equals a negative)

15x - 21

Answer:

ans of problem 12 is:

x=65

y=10

Answer:

Step-by-step explanation:

Problem 12:

I think that (2x-y)+60=(2x+y)+40

Because of the Alternate Interior Angles theorem, which places the 40 next to (2x+y) so then you know they are a linear pair. Same can be done for the side with the 60 degree angle. So both sides add up to 180 so they are congruent themselves and you can put them in this format:

(2x-y)+60=(2x+y)+40

         -40             -40

We do this to remove the 40 from the right side completely, and whatever you do to one side of the equation you have to do to the other as well so remove 40 from both.

(2x-y)+20=(2x+y)

-2x             -2x

Again, we are just trying to find out y right now

-y +20=y

+y        +y

20 = 2y

10 = y

Then insert the y into an equation telling us that it is equal to 180 (because we know that from before) to get what x is

(2x-y)+60=180

We can also input our y that we found out was 10 from before:

(2x-10)+60=180

And now we can add up 60 and -10

2x+50=180

Now subtract 50 to both sides

2x=130

And divide both sides by 2

x=75

So x=75 and y=10

Answer:

x- intercept = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2 and c = 6 , thus

y = - 2x + 6 ← is the equation of the line

To find the x- intercept, let y = 0 in the equation and solve for x

- 2x + 6 = 0 ( subtract 6 from both sides )

- 2x = - 6 ( divide both sides by - 2 )

x = 3 ← x- intercept or (3, 0 )

Answer:

4

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ 0, 4 ] , thus

f(b) = f(4) = - 4² + 8(4) - 4 = - 16 + 32 - 4 = 12

f(a) = f(0) = - 4 , then

average rate of change = [tex]\frac{12-(-4)}{4-0}[/tex] = [tex]\frac{12+4}{4}[/tex] = [tex]\frac{16}{4}[/tex] = 4
