A right triangle has one leg that measures 7 inches and the hypotenuse measures 12 inches.
kirill [66]
  • Hypotenuse=H=12in
  • Perpendicular=P=7in
  • Base=B=?

Using Pythagorean theorem

\boxed{\sf B^2=H^2-P^2}

\\  \sf \longmapsto \: b =  \sqrt{ {h}^{2}  -  {p}^{2} }  \\  \\  \sf \longmapsto \: b =  \sqrt{ {12}^{2}  -   {7}^{2} }  \\  \\  \sf \longmapsto \: b =  \sqrt{100 - 49}  \\  \\  \sf \longmapsto \: b =  \sqrt{51}  \\  \\  \sf \longmapsto \: b = 7.2in

Jerry hears 5 case ever 2 3/8 hours Jerry hears a constant rate how many case does Jerry hear per hour
irakobra [83]

Answer:

The rate of cases is \frac{40}{19} per hour

Step-by-step explanation:

we are given

Total number of cases =5

total time is

=2\frac{3}{8} hour

we can simplify it

total time is

=\frac{2\times 8+3}{8} hour

=\frac{19}{8} hour

we can use formula

rate of cases = ( total number of cases)/( total time)

now, we can plug values

Rate of cases is

=\frac{5}{\frac{19}{8} }

=\frac{40}{19}

A rectangle's length is 6 inches greater than its width. If the perimeter of the rectangle is 36 inches, find the length.
Tasya [4]

We will have the following:

First, we are given the following expressions for the rectangle's length and width respectively:

l=w+6

&

w=w

Now, we calculate the length and width using the perimeter:

P=2(l+w)\Rightarrow P=2(w+6+w)\Rightarrow P=2(2w+6)\Rightarrow P=4(w+3)

So:

36=4(w+3)\Rightarrow w+3=9\Rightarrow w=6

Then:

l=(6)+6\Rightarrow l=12

So, the measurements of the length and the width are respectively 12 units and 6 units.
