PLEASE HELP ME WITH THIS ONE QUESTION

Given:

$n=4$ and $r=3$ .

To find:

The combinations without repetition are possible if $n=4$ and $r=3$ .

Solution:

Combination of selecting r item from total n items is:

$^nC_r=\dfrac{n!}{r!(n-r)!}$

We have $n=4$ and $r=3$ . By using the above formula, we get

$^4C_3=\dfrac{4!}{3!(4-3)!}$

$^4C_3=\dfrac{4\times 3!}{3!1!}$

$^4C_3=4$

Therefore, the correct option is D.

For the graph x = 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your an

scoray [572]

Lines that are perpendicular to another line has an opposite reciprocal slope. (opposite meaning to negate the number).
Lines that are parallel have the same slope.

But the line you provided is a vertical line, and vertical lines are undefined. There is no possible perpendicular or parallel line. Maybe you gave the wrong equation and didn't put it in <em>y=mx+b</em> form. If so, you can correct it in the comments, and if not, that's you answer!

A rectangular computer table measures 30 inches by 50 inches. We need to cover it with square tiles. What is the side length of

jekas [21]

Answer:

a) 10*10 inch, b)yes, c) 15

Step-by-step explanation:

we need to calculate the Greatest Common Factor between 30 and 50

$30 = 2 \times 3 \times 5 \\ 50 = 2 \times 5 \times 5 \\ GCM = 2 \times 5 = 10$

then, the square tiles will be 10 inch *10 inch

b) it will change because they don't need to have the largest slab possible so they will use any other comon factor with a size they consider correct for the cheese.

$30 \div 10 = 3 \\ 50 \div 10 = 5 \\ 3 \times 5 = 15$

15 squares of 10inch*10inch of cheese could be cut.
