Write a fraction that is equivalent to 7/10 = _ /_

1 answer:

6 0

A fraction that is equivalent to $\frac{a}{b}$ will have the form $\frac{a\times A}{b\times B}$ , where A and B are equivalent and factors that are multiplied in.
The product fraction should be easily simplified using A and B to get the original fraction.

In the case of your fraction $\frac{7}{10}$ you will need to find a fraction which is a product of this: $\frac{7\timesA}{10\timesB},A=B$

What is the simplified form of 12x/900x²y4z6?

zalisa [80]

Answer:

$360xy^2|xz^3|$

Step-by-step explanation:

Given expression:

$12x \sqrt{900x^2y^4z^6}$

$\textsf{Apply radical rule} \quad \sqrt{ab}=\sqrt{a}\sqrt{b}:$

$\implies 12x \sqrt{900}\sqrt{x^2}\sqrt{y^4}\sqrt{z^6}$

Replace 900 with 30² :

$\implies 12x \sqrt{30^2}\sqrt{x^2}\sqrt{y^4}\sqrt{z^6}$

$\textsf{Apply radical rule} \quad \sqrt{a^2}=a, \quad a \geq 0:$

$\implies 12x \cdot 30|x|\sqrt{y^4}\sqrt{z^6}$

$\implies 360x|x|\sqrt{y^4}\sqrt{z^6}$

(We need to use the absolute value of √x² since the x term was originally to the power of 2, which means the value of x² is always positive since the exponent is even).

$\textsf{Apply exponent rule} \quad \sqrt{a^m}=a^{\frac{m}{2}}:$

$\implies 360x|x|\cdot y^{\frac{4}{2}}\cdot z^{\frac{6}{2}}$

Simplify:

$\implies 360xy^2|xz^3|$

(We need to use the absolute value of z³ since the z term was original to the power of 6, which means the value of z⁶ is always positive since the exponent is even).

3.2] I can rearrange formulas to solve for a specified variable. Solve for r. h=r-m

Lesechka [4]

Answer:

r = h + m

Step-by-step explanation:

h = r - m

Switch sides.

r - m = h

Add m to both sides.

r - m + m = h + m

Simplify the left side. -m + m = 0

r = h + m

The histogram below represents the high temperatures recorded each day over month period. Which of the following statements are

Kisachek [45]

Answer:

See possible solutions below.

Step-by-step explanation:

The statements are not given. But the following can be determined from the graph:

More days recorded temperatures between 82 and 84 then other temperatures.
The least number of days recorded temperatures between 88 and 90.
The histogram is skewed to the right also known as positive skewed distribution.
The mean and median will most likely be in the range of 82-84 temperatures. But the mean will be greater than the median.
