Answer:

7.2 m²

Step-by-step explanation:

Use the appropriate area formula, fill in the given values, and do the arithmetic.

A = (1/2)ab·sin(C)

where "a" and "b" represent triangle side lengths and C is the angle between them.

A = (1/2)(4 m)(8.5 m)sin(25°) ≈ 7.2 m²

If f(x) = 5x − 3, which expression represents its inverse function?

tangare [24]

Answer:

$f ^{-1}(x)=\frac{x+3}{5}$

Step-by-step explanation:

To find the inverse of a function f (x) follow the steps below:

1) Make y = f (x)

$y= 5x - 3$

2) Solve for the variable x

$y+3= 5x - 3+3$

$y+3= 5x$

$x=\frac{y+3}{5}$

3) Exchange the variable x with the variable y

$y=\frac{x+3}{5}$

4) Make $y = f ^{-1}(x)$

$f ^{-1}(x)=\frac{x+3}{5}$

Finally, the inverse of the function f (x) is: $f ^{-1}(x)=\frac{x+3}{5}$

There are two racks with 40 towels per rack on Tuesday there were €30,000 on Wednesday 50 and on Thursday 25 what fraction on av

ale4655 [162]

Answer:

$\frac{7}{16}$

Step-by-step explanation:

We have been given that are two racks with 40 towels per rack. On Tuesday there were 30, on Wednesday 50 and on Thursday 25. We are asked to find the fraction on average that is in use for the three days.

First of all, we will find total number of towel by multiplying 40 by 2.

$\text{Total towels}=2\times 40$

$\text{Total towels}=80$

Now we will find average number of towels used on three days.

$\text{Average}=\frac{\text{Sum of numbers}}{\text{Total numbers}}$

$\text{Average}=\frac{30+50+25}{3}$

$\text{Average}=\frac{105}{3}$

$\text{Average}=35$

Now we need to calculate 35 is what part of 80 to find the fractional use of towels per day as:

$\text{Fractional use of towels per day}=\frac{35}{80}$

$\text{Fractional use of towels per day}=\frac{7}{16}$

Therefore, $\frac{7}{16}$ on average is in use for the three days.
