Answer:
Step-by-step explanation:
Let p represent the number of pens Nick sold. Then the revenue is ...
0.10p +0.05(1000 -p) = 74.50
0.05p = 24.50 . . . . . . eliminate parentheses, subtract 50
p = 490 . . . . . . . . . . . . multiply by 20
The number of pencils sold is then ...
pencils = 1000 -490 = 510
Nick's Printing Press sold 490 pens and 510 pencils.
We know that
length of a sector=[∅]*r--------> when ∅ is in radians
so
∅=length of a sector/r
for r=7 ft
length of a sector=4 ft
∅=4/7-----> 0.57 radians
the answer part 1) is 0.57 radians
part 2)
area of a sector=(∅/2)*r²--------> when ∅<span> is in radians
</span>area of a sector=(4/7/2)*7²-----> (4/14)*49----> 14 ft²
the answer Part 2) is 14 ft²

Answer:
<em>The correct answer is </em><u><em>(-B-)</em></u>
Step-by-step explanation:
<em>Why this would be (B), A normal size shape triangle is a right angle and that would mean the L=Length, = </em><u><em>5</em></u><em>, H=Height=</em><u><em>6</em></u><em>, B=Base, = </em><u><em>5</em></u><em>. </em>
You can take 5 and 10 to turn that into 15 and + 6 = 21 x bh = 40
