Answer:

  2√42 ≈ 12.961

Step-by-step explanation:

All of the right triangles are similar, so ...

  short leg/long leg = BC/AC = AC/CD

  AC² = BC·CD = 7·24 = 168

  AC = √168 = 2√42

From the laws of logarithms, given an expression in the form;

Log ₓ y, where x is the base and y is the number, we can apply the change of base formula to a logarithmic expression to get;

Log y/log x, which are to base 10

Thus; Log₁₂1/4 = log 1/4/ log 12

Write an EXPRESSION for the following!
Anarel [89]

Answer:

The expression for 4 less than x is: x - 4

The expression for 17 more than x is: x + 17

The expression for the product of 18 and x is: 18x

The expression for the quotient of x and 17 is: x/17

The expression for 70 less than x is: x - 70

Step-by-step explanation:

4 less than x

4 less than a number is the number subtracted by 4. So the expression is x - 4.

17 more than x

17 more than a number is the number added to 17. So the expression is x + 17.

the product of 18 and x

The product of two numbers a and b is a*b, so the product of 18 and x is 18*x = 18x

the quotient of x and 17

The quotient of two numbers a and b is a/b, so the quotient of x and 17 is x/17.

70 less than x

70 less than a number is the number subtracted by 70. So the expression is x - 70.

What is the volume of the right rectangular prism?
Vlad1618 [11]

Answer:

216 cubic inches

Step-by-step explanation:

The volume of a right rectangular prism is given by the area of the base rectangle multiplied by the height.

Now, see the given figures with the question.

The base of the prism is a rectangle, and its area is (6 × 12) = 72 square inches.

Now, the volume of the prism will be (72 × 3) = 216 cubic inches (Answer)
