Since they are similar, the dimensions are in the same ratio. L1 = 5, L2 = 15, so they are in a 3:1 ratio. So if V1 = 60, then W1×H1 = 60/5 = 12
W2 must also be 3×W1 and H2 3×H1, and
3×3 = 9. So take 12×9 (W×H1×9) ×15 (L2) = V2
V2 = 12×9×15 = 1620 cm^3
Let me know the right answer when you find out!
Step-by-step explanation:
$1.80 per pound
The amount she's supposed to buy it is
1.80 × 12.5 = $22.5
She paid $21.25 for the 12.5 pounds, that means she saved
$22.5 - $21.25 = $1.25
the amount she saved per pound is
1.25/12.5 = $0.1 per pound
Hello there! This statement is TRUE.
The question is asking you if it is true that 11 - 4 is greater than 4 + 2. To get an answer, Solve both of the problems.
11 - 4 = 7.
4 + 2 = 6.
So, is 7 greater than 6? Yes, it is greater than 6 by 1. This means the answer is true. I hope this was helpful and have a great rest of your day!
Since pi is equivalent to 3.14 and means 180°, therefore 1.75 which
is about half of pi should be at almost 90°. The cos of a 90° angle which is located on
the y axis should be zero, therefore cos 1.75 must be near zero. However in
this case it is near one, clearly his calculator is in degree mode that is why
he got an erroneous answer.
What Sam
can do to get the correct answer would be to convert his calculator into radian
mode or convert the given 1.75 rad into degrees:
θ = 1.75
rad (180° / π rad)
θ =
100.2676
<span>cos 100.2676
= -0.1782 which is now correct since it
is nearer to zero</span>
