which inequality represents the following situation 3/5 times 5 less than a number is no more than 27

andrey2020 [161]

The answer is $\frac{3}{5}(x-5) \leq 27$

Let's build the expression piece by piece, translating sentences into formulas:

"3/5 times..." $\to \frac{3}{5} \times \ldots$

"5 less than a number..." $\to x-5 \ldots$

So, the first block becomes

"3/5 times 5 less than a number..." $\to \frac{3}{5}(x-5) \ldots$

"...is no more than 27" $\ldots \leq 27$

So, putting the pieces together, you have the answer

Answer:

$1,334.5 \: {cm}^{3}$

Step-by-step explanation:

Height of the cylinder h = 17 cm

Radius of the cylinder r = 5 cm

$V_{cylinder} = \pi {r}^{2} h \\ \\ = 3.14 \times {(5)}^{2} \times 17 \\ \\ = 3.14 \times 25 \times 17 \\ \\V_{cylinder} = 1,334.5 \: {cm}^{3}$

Why do you sometimes have only one multiplication sentence for an array

taurus [48]

Arrays are useful models for multiplication which can be used in a variety of ways, ranging from highly structured lessons to games and open investigations. An array is formed by arranging a set of objects into rows and columns. Each column must contain the same number of objects as the other columns, and each row must have the same number as the other rows.

The following array, consisting of four columns and three rows, could be used to represent the number sentence 3 x 4 = 12.
