Dominik [7]3 years ago
3 0

Answer:

1. Equivalent

The rest are not

Step-by-step explanation:

This is my thinking, sorry if I got it wrong...

In the first pair, 6 will be multiplied by 5, which is 30, the 6 will be multiplied by x as well. The second one is not equivalent as 4 is not multiplied. The last one is that y did not get multiplied.

1/4 foot every 3/4 hour how many feet in one hour
RUDIKE [14]

For this case we propose a rule of three:

\frac {1} {4} foot -------------> \frac {3} {4} hour

x -----------------------------------> 1 hour

Where "x" represents the amount of foot in one hour.

x = \frac {1 * \frac {1} {4}} {\frac {3} {4}}\\x = \frac {\frac {1} {4}} {\frac {3} {4}}\\x = \frac {4 * 1} {3 * 4}\\x = \frac {4} {12}\\x = \frac {1} {3}

So, we have\frac {1} {3} foot every hour.

Answer:

\frac {1} {3}foot every hour

In △XYZ , XZ=9 , YZ=4 , and XY=7 .
Mamont248 [21]

Answer:

A=6\sqrt{5}\ units^2

Step-by-step explanation:

we know that

Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.  

so

A=\sqrt{s(s-a)(s-b)(s-c)}

where

a, b and c are the length sides of triangle

s is the semi-perimeter of triangle

we have

a=9\ units,b=4\ units,c=7\ units

Find the semi-perimeter s  

s=\frac{9+4+7}{2}=10\ units

Find the area of triangle

A=\sqrt{10(10-9)(10-4)(10-7)}

A=\sqrt{10(1)(6)(3)}

A=\sqrt{180}\ units^2

Simplify

A=6\sqrt{5}\ units^2
