Answer:

The length of the other leg is 5cm

Step-by-step explanation:

Area of a right triangle = ½ * Base * Height.

Given:

Base = 4cm

Height (Length) = ??

Area = 10cm²

Area = ½ bh

10cm² = ½ * 4 * h

10cm² = 2h

Let's divide through by 2cm

h = 10cm² / 2cm

h = 5cm

The length of the other leg is 5cm

If you are saying that the hypotenuse is 10 cm the you have to solve the following equation using the Pythagorean theory.

4^2 + b^2 = 10^2

16 + b^2 = 100

16 - 16 + b^2 = 100 - 16

b^2 = 84

Find $\sqrt{84\\$

Step-by-step explanation:

Two walls have same area

Area of first wall(square) = 18*18 = 324

Area of second wall = 12 * x = 324

324/12 = 27

The skating rink rented 218 pairs of skates during the month of April and 3 times that many in May. How many pairs of skates did

Marrrta [24]

Answer: Total number of pairs =872

Step-by-step explanation:

Since we have given that

Number of pairs of skates during the month of April =218

Number of pairs of skates during the month of May =3 × 218=654

As we know that total means altogether in which we perform the additive operation.

Total pairs of skates the skating rent during April and May = 218+654=872

∴ Total number of pairs =872

What is the graph of the function f(x) = the quantity of x plus 2, all over x minus 3

Andrej [43]

Answer:

Step-by-step explanation:

The given function is $f(x)=\frac{x+2}{x-3}$ and we need to graph it.

In order to graph this function, we'll find below things:

Horizontal asymptote:

Since the degree of both numerator and denominator is same. Hence, the horizontal asymptote is the ratio of leading coefficient of numerator to the leading coefficient of denominator.

Horizontal asymptote is y = 1/1 = 1

Vertical asymptote:

Vertical asymptote occurs where the denominator is zero.

$x-3=0\\x=3$

x-intercepts:

For x-intercept, y = 0

$\frac{x+2}{x-3}=0\\\\x+2=0\\x=-2$

y-intercepts:

For y-intercept, x= 0

$y=\frac{0+2}{0-3}=0\\\\y=-\frac{2}{3}$

Using these, we can draw the graph of the rational expression.
