Hello!

To find the hypotenuse of a right triangle, we use the formula: a² + b² = c². In this formula, which is also known as the Pythagorean Theorem, a and b are the legs of the right triangle, and c is the hypotenuse, which is the value we are trying to find.

The value of leg a is 9 centimeters, and value of leg b is 12 centimeters. With those values, we can substitute it into our equation and solve.

(9)² + (12)² = c² (simplify the exponent)

81 + 144 = c² (simplify)

225 = c² (take the square root of both sides)

c = 15

Therefore, the length of the hypotenuse is 15 centimeters.

To find this out, you use the Pythagorean theorem which is;

a^2 + b^2 = c^2

where a & b are the legs and c is the hypotenuse. now simply plug them in their rightful place and solve.

9^2 + 12^2 = c^2

81 + 144 = c^2

225 = c^2

15 = c

hope this helped, blessings :)

Answer:

D. 144

Step-by-step explanation:

Find volume of shipping container:

2 2/3 = 8/3

2 x 1 = 2

8/3 x 2/1 = 16/3

Find volume of cube:

1/3 x 1/3 = 1/9 x 1/3 = 1/27

Find how many boxes fit in container:

16/3 ÷ 1/27

16/3 x 27/1

Simplify:

16/1 x 9/1 = 144/1

Need help with this

Vanyuwa [196]

Answer:

Slope-int form: y = 3x+5

Standard form: y - 3x = 5.

Step-by-step explanation:

(reminder: slope-intercept form is expressed as y=mx+b, and standard form is expressed as ax+bx=c.)

Since the slope is 3, the coefficient of x is also 3, which makes the equation y=3x.

But the y coordinate of the equation at x = -2 is -6, so we need to add 5 to the end of the equation, leaving you with:

y=3x+5.

To convert it to standard form, subtract 3x from both sides:

y - 3x = 5.

I hope this helped you.

PLEASE HELP ! The total cost after tax to repair Kimber's cracked phone screen is represented by 0.04(30h)+30h where h represent

Ronch [10]

Answer: The term 0.040(30h) represents the amount of tax she must pay.

Explanation:

The functin 0.04(30h) + 30h, has two terms; the second term, 30h, represents cost due to h hours at at unit of 30, and the first term 0.04(30h) is the additional amount due to the taxes over h hours at the unit rate of 30.

When you add a tax rate of 4% to 30h, you get the the amount of taxes over the 30h.

The calcualtion is: (4/100)×(30h) = 0.04(30h). Hence, you conclude that 0.04(30h) is the amount of tax she must pay.

The president of a certain university receives a salary that is three times the salary of one of the department heads. The total

marissa [1.9K]

Answer:

Salary of President = $180,000

Salary of Dept. Head = $60,000

Step-by-step explanation:

The question is to find the salary of president and department head.

We let the salary of one of department heads be "x"

Since, the salary of president is THREE (3) TIMES a department head, we can say:

Salary of President = 3x

Now, we know the total of these 2 salaries is 240,000. Thus, we can write:

Salary of President + Salary of Dept. Head = 240,000

3x + x = 240,000

Now, we can solve for x:

$3x + x = 240,000\\4x=240,000\\x=60,000$

And now the president is "3x", so his salary is:

3(60,000) = 180,000

Thus,

President's salary = 180,000

Dept head's salary = 60,000
