Mathematics

lidiya [134]3 years ago
5 0

Answer:

The answer is \frac{2}{3}

Step-by-step explanation:

When we divide two fractions, we multiply the numerator by the inverse of the denominator. So

\frac{\frac{a}{5}}{\frac{3a}{10}} = \frac{a}{5} \times \frac{10}{3a} = \frac{10*a}{5*3a} = \frac{10a}{15a} = \frac{2}{3}

The answer is \frac{2}{3}

A rectangular trunk has a volume of 26,880 cubic inches. The trunk is 4 feet long by 28 inches wide. How deep is the trunk?
ioda
The answer would be, 20 inches, 12 inches in a foot multiplied by 4 feet equals 48 inches, now take 48 inches and multiply it by 28 inches which equals 1,344, then take 26,880 inches and divide it by 1,344 and your answer would be 20 inches. To check your answer the fourmula for volume for that object is, length x width x hight, so you take 48x28x20 and you get a volume of 26,880 inches. I hope that helped.

Given the function
jeka94

Answer:

<h2>The domain is all real numbers except</h2><h2>x = 3 and x = 7.</h2>

Step-by-step explanation:

We know that in a fraction the denominator must be different from 0.

Therefore:

f(x)=\dfrac{4x+17}{x^2-10x+21}\to\ D:x^2-10x+21\neq0\\\\x^2-7x-3x+21\neq0\\\\x(x-7)-3(x-7)\neq0\\\\(x-7)(x-3)\neq0\iff x-7\neq0\ \wedge\ x-3\neq0\\\\x-7\neq0\qquad\text{add 7 to both sides}\\x\neq7\\\\x-3\neq0\qquad\text{add 3 to both sides}\\x\neq3
