Answer:
X=90°
Y=58°
Z=32°
Step-by-step explanation:
X=180°-90°=90°
Y=180°-90°-32°=58°
Z=180°-58°-90°=32°
Answer:
MN = 7 cm
Step-by-step explanation:
Well the volume we can separate into pieces
first the ABCDEFGH (? you know this cuboid)
which has a volume of
if you ask where does the 4 come from
it comes from LP = KB = YC and JY + YC =JC
so
this is because JY = MX
the other volume is of BCNPKLXY (hope you understand which one)
and the volume is
and the last one is KYXLMJ (the top "triangle")
the volume is
so now add them up
and has to equal 444
and finally we know that MN = MX + XN = 3+4 = 7
so here is our answer MN = 7 cm
a couple of notes
3. the units don't matter due to the fact that everything is in cm
4. see the picture below to get a better idea of which prism I am talking of
5. tell me if you have questions :D

Step-by-step explanation:
n = 27000 + 3000(10 - p)
n = 27000 + 30000 - 3000p
n = 57000 - 3000p
D=2n: there are twice as many dimes as nickels.
n+d+q=52: a total of 52 coins, using d from above in this gives you:
n+2n+q=52 combine like terms on left side
3n+q=52 subtract 3n from both sides
q=52-3n
Then you are told that the coins have a total value of $6 which is equal to 600 cents. So we can say:
25q+10d+5n=600 divide all terms by 5
5q+2d+n=120, and from earlier we saw q=52-3n and d=2n so you have:
5(52-3n)+2(2n)+n=120 expanding...
260-15n+4n+n=120 combining like terms
260-10n=120 subtract 260 from both sides
-10n=-140 divide both sides by -10
n=14, since q=52-3n and d=2n
q=(52-3(14))=52-42=10
d=2(14)=28
So there are 10 quarters, 28 dimes, and 14 nickels or as your choices put it:
q=10, d=28, n=14 (the correct answer is d.)
Answer:
it might be 2/1
Step-by-step explanation:
first u do rise over run- u find the spot on the x axis that goes through the x axis line, and then u rise up until u reach other spot that is going through on the end point and then u run right because its a positive number and u go right however many until u reach that end point, i hope that makes some sense
