Answer:
(6r+7)+(13+7r)=13r+20
(13-1/2r)-(1-r)=12-1/2r
(-8-r)+(2r-4)=-12+r
Last one is r-13/6
Step-by-step explanation:
<span>In the form of a/b = c/d in proportions in math,
the outer terms are called the extremes and the inner terms are called means.
In the given 3/4 = 15/20, the outer terms or the extremes are 3 and 20.</span>
Answer:
11 shirts
Step-by-step explanation:
Since 12 of the 45 minute are devoted to setup, the actual printing time is 33 minutes. At 3 minutes per shirt, that's enough time for ...
(33 min)/(3 min/shirt) = 11 shirts
A batch consists of 11 shirts.
_____
<em>Alternate solution</em>
Another way to consider this is to realize that the setup time is the time required to print 4 shirts. 45 minutes would be enough time to print 45/3 = 15 shirts, but the time for 4 shirts is spent setting up. That leaves the batch size at 15 -4 = 11 shirts.
Answer:
3
Step-by-step explanation:
The equation for the area of a triangle is A=1/2(b)(h)
we have the area and the base, so we plug those values in resulting in 7 7/8=1/2(5 1/4)(h)
From there, we solve. Multiply 5 1/4 by 0.5, resulting in 2.625
then, you divide 7 7/8 by 2.625 and you get 3.
