if I have to add 97 oz of algaecide to 10,000 gallons of water how much should I add if I only have 200 gallons of water

juin [17]

Answer:

1.94 oz

Step-by-step explanation:

x/97 = 200/10000

97*200 = 10,000x

19400 = 10,000x

1.94 oz

You can also do it this way:

200/10000 = 0.02

0.02 * 97 = 1.94

Answer:

y=x+70

Step-by-step explanation:

Slope of 1, and has a y-intercept of 70. So slope-intercept form would be y=m(x) +b where M is the slope and B is the intercept.

A curve has equation y=x√x.find the equation of the tangent to the curve at the point(1, 5)

rewona [7]

Answer:

y - 5 = $\frac{3}{2}$ (x - 1)

Step-by-step explanation:

Note that $\frac{dy}{dx}$ = $m_{tangent}$

Differentiate using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given

y = x $\sqrt{x}$ = x. $x^{\frac{1}{2} }$ = $x^{\frac{3}{2} }$ , then

$\frac{dy}{dx}$ = $\frac{3}{2}$ $x^{\frac{1}{2} }$

When x = 1

$\frac{dy}{dx}$ = $\frac{3}{2}$ . 1 = $\frac{3}{2}$

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = $\frac{3}{2}$ and (a, b) = (1, 5), thus

y - 5 = $\frac{3}{2}$ (x - 1) ← equation of tangent

Need someone with a big brain to help lol<br> Solve for x

AfilCa [17]

Answer:

x=4

Step-by-step explanation:

Hey there!

I am going to use this image as an example so you can understand the formula

The formula for problems like these is

B(BA)=D(DC)

So all we have to do is plug in the numeric values

so now we have 5(5+x+3)=6(6+x)

now we just solve for x

5(5+x+3)=6(6+x)

step 1 distribute the 5 to what is in the parenthesis (5, x and 3)

5x5=25

5*x=5x

5x3=15

so now we have

25+5x+15=6(6+x)

step 2 distribute the 6 to what is in the parenthesis (6 and x)

6x6=36

6*x=6x

now we have

25+5x+15=6x=36

step 3 combine like terms, the only like terms are 25 and 15

15+25=40

now we have

40+5x=6x+36

step 4 subtract 5x from each side

5x-5x cancels out

6x-5x=x

now we have

40=x+36

step 5 subtract 36 from each side

40-36=4

36-36 cancels out

now we have

x=4 so we can conclude that x=4

hope this helps :)
