Paul [167]

Answer:

It should take 3.43 days for the two of them to paint the house if they work together.

Step-by-step explanation:

The together rate is the sum of each separate rate.

In this problem:

Together rate: 1/x

Adam's rate: 1/8

Judy's rate: 1/6.

So

Together rate = Adam's rate + Judy's rate

\frac{1}{x} = \frac{1}{8} + \frac{1}{6}

\frac{1}{x} = \frac{3 + 4}{24}

\frac{1}{x} = \frac{7}{24}

7x = 24

x = \frac{24}{7}

x = 3.43

It should take 3.43 days for the two of them to paint the house if they work together.

What is the value of c in the equation below?<br> 24.2²= abac
Bingel [31]

Answer:

The value of c in the equation c =6.

Step-by-step explanation:

In mathematics, a perfect square or a square number is an integer that is the square of an integer. In different words, it is the product of an integer with itself. For example, 9 is a square number because it can be written in 3 × 3.

The normal notation for the square of a number n is not the product n × n, but the equivalent exponentiation n2, which is generally pronounced as "n square". The square number of the name results from the name of the form. The unit area is defined as the area of a unit square (1 × 1). Consequently, a square of lateral length n has the area n2.

Square numbers are not negative. Another way to say that an integer (not negative) is a square is to make its square root an integer again.

For example, √9 = 3, so, 9 is a quadratic number.

A positive integer that has no perfect square divisors other than one is called without a square.

24.2² = 24.2 × 24.2 =585.64=abac.

From above equation, a=5,b=8,c=6.
