Answer:
4000 should be 40 to be correct. simple wrong steps.
Step-by-step explanation:
D+q=26, so we can say d=26-q
Then we are told:
.1d+.25q=5.15, using d found above makes this equation become:
.1(26-q)+.25q=5.15 perform indicated multiplication on left side
2.6-.1q+.25q=5.15 combine like terms on left side
2.6+.15q=5.15 subtract 2.6 from both sides
.15q=2.55 divide both sides by .15
q=17, and since d=26-q
d=26-17
d=9
So there are 9 dimes and 17 quarters.
Answer:
543
Step-by-step explanation:
From 0 to 535 is a distance of 535 to the right
From 0 to - 8 is a distance of 8 to the left
-----------------------
535 + 8 = 543
The volume formula for a cylinder is <em>V = pi r^2 h.
</em>Plugging in the numbers, we get <em>V = 3.14 * 5^2 * 2, </em>which is equal to 157!<em>
</em>
