Hey there!

Guide for you do tackle them on your own in the nearer future.

• Percentages are out 100

• The word “of” means MULTIPLY in mathematics

1.)

10% of 40

10% = 10/100

= 10/100 • 40

10/100 = 1/10

1/10 • 40

40/10 = 4

4/1 = 4

Answer: 4 ☑️

2.)

25% of 8

25% = 25/100

= 25/100 • 8

25/100 = 1/4

1/4 • 8

8/4 = 2

2/1 = 2

Answer: 2 ☑️

3.)

20% of 5

20% = 20/100

= 20/100 • 5

20/100 = 1/5

1/5 • 5

5/5 =1

1/1 = 1

Answer: 1 ☑️

Good luck on your assignment and enjoy your day!

Find y' by implicit differentiation √x +√y =1
AleksandrR [38]
Differentiate both sides with respect to x

\frac{d}{dx}(x^{\frac{1}{2}} + y^{\frac{1}{2}}) = \frac{d}{dx}(1)\\\\ \frac{1}{2x^{\frac{1}{2}}} + \frac{1}{2y^{\frac{1}{2}}}\frac{dy}{dx} = 0\\\\\frac{1}{2y^{\frac{1}{2}}}\frac{dy}{dx} = -\frac{1}{2x^{\frac{1}{2}}}\\\\\frac{1}{2\sqrt{y}}\frac{dy}{dx} = -\frac{1}{2\sqrt{x}} \\\\\frac{dy}{dx} = -\frac{1}{2\sqrt{x}} \times 2\sqrt{y}\\\\\frac{dy}{dx} = -\frac{\sqrt{y}}{\sqrt{x}} \\\\\boxed{\bf{y'= -\frac{\sqrt{y}}{\sqrt{x}}}}

Madie drove 200 miles at a speed of 50 miles per hour. Which equation will help you find the number of hours she was driving? St
aalyn [17]

Answer:

  StartFraction 50 miles Over 1 hour EndFraction = StartFraction 200 miles Over question mark hours EndFraction

Step-by-step explanation:

For constant speed, miles and hours are proportional. One possible equation is ...

  \dfrac{50\,\text{miles}}{1\,\text{hour}}=\dfrac{200\,\text{miles}}{?\,\text{hours}}\qquad\text{matches the first choice}

_____

<em>Comment on the solution</em>

I personally like to put the unknown in the numerator, so the equation can be solved in one step. The equation above requires two steps: one to cross-multiply, and one to divide by 50.

I might write the equation as ...

  (? hours)/(200 mi) = (1 hour)/(50 mi) . . . . multiply by 200 mi to solve

Another way to write the equation is matching the ratios of times to corresponding miles:

  (? hours)/(1 hour) = (200 mi)/(50 mi)

This only requires simplification to solve it: ? = 4.
