Answer:

Given the information, the value of x is 20.

Step-by-step explanation:

For this problem, we have to find  the ratio between the line segments in order to find the value of x.

We are already given two line segments that we can find the ratio for. We are given 30 and 12. In order to find the ratio, then we must divide 12 by 30.

12 ÷ 30 = 0.4

Now that we have our ratio, we can now divide 8 by 0.4 to find the value of x.

8 ÷ 0.4 = 20

So, the value of x is 20 which is the third answer choice in the problem.

Nathan bought a cd for his friend. The length and width of the cd case is 4 18⁄25 inches. What is the area of the cd case?
ale4655 [162]

Answer:

Hence the area of CD bought by Nathan is <em>22.2784 square inches.</em>

Step-by-step explanation:

The length and width of a CD bought by Nathan is 4\frac{18}{25}=\dfrac{118}{25} inches.

As CD have the same length and width this means it will be of the shape of a square.

Hence, the area of CD is given by:

Area of CD=length×width

                 = 4\dfrac{18}{25}\times4\dfrac{18}{25}

                 =\dfrac{118}{25}\times\dfrac{118}{25}

                 =\dfrac{118\times118}{25\times25}

                 =\dfrac{13924}{625}

                 =22.2784

Hence the area of CD bought by Nathan is 22.2784 square inches.

What is the simplified form of 5 square root x^4 • 5 square root x^4
laiz [17]

Answer: C

Step-by-step explanation:

You can write each term into a fraction.

\sqrt[5]{x^4} becomes x^4^/^5

When you multiply 2 terms with the same base, you add the exponents.

x^4^/^5*x^4^/^5=x^4^/^5^+^4^/^5=x^8^/^5

x^8^/^5 is also the same as x\sqrt[5]{x^3}

You get this because \sqrt[5]{x^8} =\sqrt[5]{x*x*x*x*x*x*x*x}. When you pull out 5 os x, you are left with x³ on the inside.

Answer:

The correct answer is option C.

Step-by-step explanation:

The lower your interest rate is, the lower your monthly payments are. This is true. The interest rate is directly proportional to monthly or yearly payments. If the rates are high, the installments are high and if the rate of interest is low, the installments are lower.
