Three and one tenths divided by two and three fourth

Hi there.

So, we have a division problem.

3 1/10 / 2 3/4

What we can do is change them to improper fractions, and multiple. We flipped the numerator & denominator of 2 3/4 first, though.

31/10 / 11/4 = 31/10 * 4/11

31/10 * 4/11 = 1 7/55

I hope this helps! I didn't use a calculator so I'm a little skeptical of it came out right.

What is the average rate of change of the function over the interval x = 0 to x = 8?
notsponge [240]
To find the average rate of change, use the following formula:

\frac{f(b) - f(a)}{b-a}

a and b represent the values of the interval:

a = 0, b = 8

Simplify the original equation by combining like terms:

2x - 13x = -11x
f(x) = -11x + 5

Plug the interval values into the f(x) equation:

f(0) = -11(0) + 5 = 0 + 5 = 5
f(8) = -11(8) + 5 = -88 + 5 = -83

Plug in these values into the average rate of change formula:

\frac{-83 - 5}{8 - 0} =  \frac{-88}{8} = -11

The average rate of change over this interval is -11.

choli [55]

Answer:

9/2

Step-by-step explanation:

In order to find the slope of a line that is perpendicular to another line, you must find the opposite and reciprocal of that slope. So, you have 2/9, and then 9/2.

The angle made by the ladder with the ground is degrees, and the length of the ladder is inches.
aleksley [76]

Answer:

59.04°

58.31 inches

Step-by-step explanation:

The solution triangle is attached below :

Since we have a right angled triangle, we can apply trigonometry to obtain the angle ladder makes with the ground;

Let the angle = θ

Tanθ = opposite / Adjacent

Tanθ = 50/30

θ = tan^-1(50/30)

θ = 59.036°

θ = 59.04°

The length of ladder can be obtained using Pythagoras :

Length of ladder is the hypotenus :

Hence,

Hypotenus = √(adjacent² + opposite²)

Hypotenus = √(50² + 30²)

Hypotenus = √(2500 + 900)

Hypotenus = 58.309

Length of ladder = 58.31 inches
