Answer: 11/20 = 55% and Grid A

Step-by-step explanation:

By doing 11/20 and making the denominator 20 into 100 by multiplying it by 5 we can get 55/100 which is 55%. And by simply counting the squares on the grid we can see 55 squares are shaded and the other 45 aren't showing its 55% shaded.

A researcher wants to determine whether the rate of water flow (in liters per second) over an experimental soil bed can be used

pantera1 [17]

Here we are given the specific equation of:

amount of eroded soil = 0.4 + 1.3 x

where x is the flow rate

A linear equation has a general formula in the form of:

y = m x + b

where m is the slope and b is the y intercept of the equation

If we compare this with our specific equation, we can see that the slope and y intercept are both positive with values:

m = 0.4

b = 1.3

Therefore this only means that as the flow rate increases, the amount of eroded soil also increases.

Hence the correlation must be positive but we cannot solve for the exact value since we need the data for x and y.

Answer:

positive, but we cannot say what the exact value is

An item on sale costs 25% of the original price. If the original price was $60 , what is the sale price?

kow [346]

Answer:$45

Step-by-step explanation:

First you have to find 25% of 60

Which equals 15

60-15=45

$45

Simplify the fraction and state the excluded value(s).

stira [4]

Answer:

$\displaystyle \frac{7x^2 + 4x - 20}{5x + 10} = \frac{7x - 10}{5}, x \neq -2$

Discontinuities

Removable (Holes)
Jump (Piece-wise functions)
Infinite (Asymptotes)

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{7x^2 + 4x - 20}{5x + 10}$

Step 2: Simplify

[Frac - Numerator] Factor quadratic: $\displaystyle \frac{(7x - 10)(x + 2)}{5x + 10}$
[Frac - Denominator] Factor GCF: $\displaystyle \frac{(7x - 10)(x + 2)}{5(x + 2)}$
[Frac] Divide/Simplify: $\displaystyle \frac{(7x - 10)}{5}, x \neq -2$

When we divide (x + 2), we would have a removable discontinuity. If we were to graph the original function, we would see at x = -2 there would be a hole in the graph.
