Answer: 1680 inches cubed
Step-by-step explanation:
Volume = Length x Width x Height
V = 20 x 7 x 12
V = 140 x 12
V = 1680 inches cubed
Answer:
<h2>
<em><u>W</u></em><em><u>=</u></em><em><u>10CM</u></em></h2>
Step-by-step explanation:
5×4=20÷2=10
4×2.5=10
Secd(38)
= 1/cosd(38)
= 1/sqrt[1-sind^2(38)] because cos^2(x) + sin^2(x) = 1
cos(30) = sqrt(3)/2 = 0.8660
cos(45) = 0.707
so cos(38) can be assumed to some where around 0.8
= 1/0.8
= 1.25
Therefore D is correct answer
3/8 times 2/5 is 6/40 or 0.15. Just multiply straight across
0.00037 = 3.7×10^-4
37,000 = 3.7×10^4
_____
The exponent of 10 is the place-value multiplier that the most-significant digit has.
In the first number, the most-significant digit (3) is multiplied by 0.0001 to find its place value. Of course 0.0001 = 10^-4.
In the second number, the most significant digit (3) is multiplied by 10,000 to find its place value. You know that 10,000 = 10^4.
