X= base

Area= 1/2(base)(height)
24=1/2(b)(4)
24=(4*1*b)/2
24=4b/2
Divide 2 into 4
24=2b
Divide both sides by 2
12=b

base= x= 12 units

Hope this helps! :)

Which statement is true? Question 2 options: All parallelograms are rectangles. All rectangles are squares. All quadrilaterals a

alekssr [168]

For this case, we have that:

By definition, a rectangle is a parallelogram. So, we discard the first option.

On the other hand, we have that all rectangles can not be squares, since a square has all its sides equal, while the rectangle, poir definition, no.So, we discard the second option.

All quadrilaterals are not rectangles because there are other figures with four sides that are not necessarily rectangular. We discard the third option.

Finally, we have that all squares are rectangles. This statement is true since squares can be rectangles with pairs of equal sides.

The time required to complete a job varies inversely as the number of people working. it took 4 hours for 7 electricians to wire

Solnce55 [7]

Let's assign variables

The time required to wire a building: y

The number of electricians to have done this job: x


y varies inversely as x

so that:
$y= k\frac{1}{x}$
where k is the proportional constant

To calculate the value of k, plug in the values of x and y:
x=7
y=4

$4=k (\frac{1}{7}) \\~\\k=28$

Now, write down the relation between x and y:
$y=28x$

"how long would it have taken 3 electricians to have done the job?"
x=3
Let's find out y:
$y=(28) \frac{1}{3} = \frac{28}{3} =9 \frac{1}{3} =9.333333~~hr$

So it would take 9 hours and 20 minutes to have this job done.
