Solve the volume formula V= lwh for l. a. l=Vwh b. l=V/wh c. l=V/h+w d. l=wh/V

1 answer:

5 0

$V=lwh\to lwh=V\ \ \ \ |divide\ both\ sides\ by\ (wh)\\\\Answer:\boxed{l=\frac{V}{wh}}\ where\ w\neq0\ and\ h\neq0\to\boxed{\boxed{b.}}$

Which of the following expressions represents the least common multiple of 15, 18, and 25?

Virty [35]

Answer:

$(2)(3^2)(5^2)$

Step-by-step explanation:

we know that

The Least Common Multiple (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers.

we have

15,18 and 25

Decompose the numbers in prime factors

$15=(3)(5)$

$18=(2)(3^2)$

$25=(5^2)$

Multiply common and uncommon numbers with their greatest exponent

The LCM is equal to

$LCM=(2)(3^2)(5^2)$

$LCM=450$

If a sphere has a radius of 2 cm what is the approximate surface area of the sphere

xenn [34]

The formula for the surface area of a sphere is $SA=4 \pi r^{2}$
If your radius is 2, then filling in that formula looks like this:
$SA=4 \pi ( 2^{2} )$ or $16 \pi$ . If you leave your answer in terms of pi, which is the exact answer, you're done. But if you multiply pi in, your surface area is SA = 50.264 square cm.
