Answer:

multiply the number in each can by the number of cans and add the extras

Step-by-step explanation:

You can add them all up. This is the total of the number in each can and the extras:

8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +7

Or you can take advantage of the invention of multiplication to simplify repeated addition. Multiply the number in each can by the number of cans, then add the extras.

15×8 +7 = 127

In the stock market an amazon stock share rose 4 and 1/2 points on Wednesday rose 3 and 3/8 points on Thursday and fell 2 and 1/

Vika [28.1K]

Answer:

In the three days the Amazon stock share rose by $5\frac{5}{8}$

Step-by-step explanation:

Given:

Amazon stock share

rose 4 and 1/2 points on Wednesday

rose 3 and 3/8 points on Thursday

fell 2 and 1/4 points on Friday

To find the overall change.

Solution:

The change in share on Wednesday is given as = $+4\frac{1}{2}$

The change in share on Thursday is given as = $+3\frac{3}{8}$

The change in share on Friday is given as = $-2\frac{1}{4}$

Thus, the over all change is given by:

$4\frac{1}{2}+3\frac{3}{8}-2\frac{1}{4}$

In order to combine mixed numbers, we will work the whole numbers and the fractions separately.

⇒ $(4+3-2)+(\frac{1}{2}+\frac{3}{8}-\frac{1}{4})$

⇒ $5+(\frac{1}{2}+\frac{3}{8}-\frac{1}{4})$

To combine fractions, we will take least common denominator.

The L.C.D. 2,4 and 8 = 8 as it is the least common multiple for all the denominators

So, we multiply the numerators with the corresponding numbers to make the denominators common.

⇒ $5+(\frac{1\times 4}{2\times 4}+\frac{3}{8}-\frac{1\times 2}{4\times 2})$

⇒ $5+(\frac{4}{8}+\frac{3}{8}-\frac{2}{8})$

Combining the numerators.

⇒ $5+\frac{4+3-2}{8}$

⇒ $5+\frac{5}{8}$

⇒ $5\frac{5}{8}$

The overall change for the three days can be given as : $+5\frac{5}{8}$

This means the share rose by $5\frac{5}{8}$

What is the surface area-to-volume ratio of the spherical barrel cactus

Butoxors [25]

I can't speak to the cactus specifically, but any sphere has a surface area of $4\pi r^2$ and a volume of $\frac{4}{3} \pi r^3$ , so the area-to-volume ratio wold be

$\frac{4\pi r^2}{ \frac{4}{3}\pi r^3 } = \frac{3(4\pi r^2)}{4(\pi r^3)}$

$= \frac{3\pi r^2}{\pi r^3}\\\\
= \frac{3}{r}$

Where r is the radius of the sphere.
