Answer:

Step-by-step explanation:

The mechanical advantage of a machine is the ratio of the force that you need to input to how much is outputted. 200:1000=1:5, meaning that the mechanical advantage is 5. Hope this helps!

Find the missing measures of the parallelogram UT= ST= VS= VT=

12345 [234]

Answer:

see explanation

Step-by-step explanation:

In a parallelogram

• opposite sides are congruent

• the diagonals bisect each other

Then

UT = 27 ( congruent to RS )

ST = 18 ( congruent to RU )

VS = 7 ( congruent to UV )

VT = 15 ( half of RT )

What is the rate of change for a linear function that passes through the points (8, -10) and (-6, 14)

Anna71 [15]

Answer: $m=-1.714$

Step-by-step explanation:

By definition, the slope of the line is described as "Rate of change".

You need to use the following formula to calcualte the slope of the line;

$m=\frac{y_2-y_1}{x_2-x_1}$

In this case you know that the line passes through these two points: (8, -10) and (-6, 14).

Then, you can say that:

$y_2=-10\\y_1=14\\\\x_2=8\\x_1=-6$

Knowing these values, you can substitute them into the formula for calculate the slope of a line:

$m=\frac{-10-14}{8-(-6)}$

Finally, you must evaluate in order to find the slope of this line. You get that this is:

$m=\frac{-24}{8+6}\\\\m=\frac{-24}{14}\\\\m=-\frac{12}{7}\\\\m=-1.714$

It takes levar four hours to drive 252 miles what is levar unit rate at this rate how far will Levar Drive in seven hours

otez555 [7]

In four hours, he drives: = 252

So, Unit rate = 252/4 = 63 mph

In seven hours, it would be = 63 * 7 = 441 miles

Hope this helps!

The volume of a cube is 460cm3. Work out the length of its side rounded to 1 DP.

yaroslaw [1]

The side length is the cube root of 460.

cube root(460) = 460^(1/3)
That's approximately 7.7
