Answer:

I'll try answering as much as I could and can see :)

Step-by-step explanation:

1) 6/11 ÷ 2/5 = 15/11 or 1.3636... or 1 4/11 as a mixed number.

2) 8,299 ÷ 43 = 193

3) 28.40 x 0.87 = 24.708

4) 3,948.99 + 489.08 = 4438.07

5) What is 40% of 90 = 36

6) Greg kicked the soccer ball 75 feet. How many yards did he kick the ball? 25 yards

7) Write an expression that represents 72 divided by n plus 4? 72/n+4

8) How many feet are in 3 miles? 15840

hey this is all I can do and see but I hope this helps. p.s. I really need brainliest :)

Derivative Notation

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

$\displaystyle y = \frac{3}{2x^2}$

$\displaystyle \text{Point} \ (1, \frac{3}{2})$

Step 2: Differentiate

[Function] Rewrite [Exponential Rule - Rewrite]: $\displaystyle y = \frac{3}{2}x^{-2}$
Basic Power Rule: $\displaystyle y' = -2 \cdot \frac{3}{2}x^{-2 - 1}$
Simplify: $\displaystyle y' = -3x^{-3}$
Rewrite [Exponential Rule - Rewrite]: $\displaystyle y' = \frac{-3}{x^3}$

Step 3: Solve

Substitute in coordinate [Derivative]: $\displaystyle y'(1, \frac{3}{2}) = \frac{-3}{1^3}$
Evaluate exponents: $\displaystyle y'(1, \frac{3}{2}) = \frac{-3}{1}$
Divide: $\displaystyle y'(1, \frac{3}{2}) = -3$

A bag of skittles has 50 pieces of candy what percentage is orange ps. there are 11 orange skittles

Oliga [24]

Answer:

I think the answer is 22% but I am not sure

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 50 is 100% since it is our output value.

Step 2: We next represent the value we seek with X

Step 3: From step 1, it follows that 100%=50

Step 4: In the same vein, x%=11.

Step 5: This gives us a pair of simple equations:

100%=50(1).

X%=11(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the left hand side of both equations have the same unit; we have

100% / X% = 11 / 50

X = 22%

Step 7: Taking the inverse (or reciprocal) of both sides yields

X% / 100% = 11 / 50

Therefore, 11 is 22% of 50.

Isaiah measured a house and made a scale drawing. In real life, the hall closet is 5 feet long. It is 10 inches long in the draw

Kazeer [188]

Answer: The answer is a scale factor of 6

Step-by-step explanation:

5 feet is 60 inches, and on the drawing the closet is 10 inches while the real closet is 5 feet, so just divide 60 by whatever gets you 10.
