Ill work it out w/ the steps so you can do it later on. STEP 1) multiply 95 by .10 to get 9.5 STEP 2) subtract 9.5 from 95 to get 85.5, your new price STEP 3) multiply 85.5 by 1.045 *mini step to get 1.045: add 4.5 to 100, get 104.5, divide by 100, get 1.045* then you get $89.35

A=½(a+b)h solve for h
allochka39001 [22]

The object is to get everything except for "h" on one side of the equation.

The equation says that everything on the right side is being multiplied by 1/2.

What do we have to multiply times 1/2 to get 1? The answer is 2.

So multiply both sides by 2 to get rid of the fraction.

2A = (a+b)h

Now we are multiplying h times (a+b) so to get rid of (a+b) we have to divide both sides by that term.

(a+b)/(a+b) is 1

So you are left with: 2A/(a+b) = h

Done!

 Jalen is painting her great room including the ceiling but not the floor. The room measures 20 ft long, 30 wide and 9 ft tall.
Luden [163]

4 cans of paint

\sf --->  \ \ {\boxed {\boxed {\frac{area  \ of \ room - area \ of \ floor}{area \ the \ paint \ covers} }}}

\hookrightarrow \sf {\dfrac{2(wl+hl+hw)- (lw)}{400}}

\hookrightarrow \sf {\dfrac{2((30)(20)+(9)(20)+(9)(30))-(20*30)}{400}

\hookrightarrow \sf {\dfrac{1500}{400}

\hookrightarrow \rm {\sf {3.75}}

→ She should buy max 4 cans as she cannot buy 3.75 cans.

<em>Here </em><em>l</em><em> refers to length, </em><em>w</em><em> refers to width, </em><em>h</em><em> refers to height.</em>
