Answer 1

Answer:

JK = 3[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos60° = [tex]\frac{1}{2}[/tex] , then

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{JK}{JL}[/tex] = [tex]\frac{JK}{6\sqrt{3} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2JK = 6[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

JK = 3[tex]\sqrt{3}[/tex]

Answers

Answer:

x = 4 sqrt(5)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

8^2 + x^2 = 12^2

64+ x^2 =144

Subtract 64 from each side

x^2 = 144-64

x^2 =80

Take the square root of each side

sqrt(x^2) = sqrt(80)

x = sqrt(16*5)

x = 4 sqrt(5)

Find the compound interest on 5000 at 12% interest for 15 years.
if the interest is compounded semi-annually.

Answers

18000

Step-by-step explanation:

5000*12%= 600 600× 30= 18000 15 years semi annually = 30 x

The compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58

To find the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually, we can use the formula:

A = P(1 + r/n)^(n*t)

where:

P = principal amount = $5,000

r = annual interest rate = 12% = 0.12

n = number of times compounded in a year = 2 (compounded semi-annually)

t = time period in years = 15

A = amount after t years

Plugging in the values, we get:

A = 5000(1 + 0.12/2)^(2*15)= $27,243.58

So, the amount after 15 years is $27,243.58. To find the compound interest, we can subtract the principal amount from the amount after 15 years:

Compound interest = A - P

= $27,243.58 - $5,000

= $22,243.58

Therefore, the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58.

I'm doing a math test, and I don't understand this question. How many 1/3 inch cubes does it take to fill a box with width 2 2/3 inches, length 3 1/3 inches, and height of 2 1/3 inches?

Answers

Answer: 62

Step-by-step explanation:

First and foremost, we have to calculate the volume of the box which will be:

= 2 2/3 × 3 1/3 × 2 1/3

= 8/3 × 10/3 × 7/3

= 560/27

= 20 20/27

The number of 1/3 inch cubes needed to fill the box will then be:

= 20 20/27 ÷ 1/3

= 560/27 ÷ 1/3

= 560/27 × 3

= 560/9

= 62 2/9

Therefore, 62 boxes can be filled

A) [tex]-\frac{7}{4}[/tex]

Step-by-step explanation:

For this question, we can use the rise over run method, which means y over x.

So count how many it takes for the point on top to get to the bottom by x and y.

It takes 7 spaces down (y)  and 4 spaces to the right (x)

So do rise over run and we get

[tex]\frac{7}{4}[/tex]

Meaning that B and C are incorrect. Now what about A and D?

Well the slope is moving down, meaning that it is a negative slope, therefore there must be a negative sign for the slope.

[tex]-\frac{7}{4}[/tex]

A. is correct.

she can buy 5 shirts maximum

100-53.84=46.16 that is how much she has left to spend on shirts. 46.16÷8.19=5.63 but you can't have 0.63 shirts so in the end she can buy 5 shirts
