An excellent swimmer is confident he can judge his speed in the water exactly. He bets he can swim two lengths of a 50-meter Oly

mpic size pool at an average speed of precisely 2 meters per second. On his first lane he is a little bit slow and ends up going at 1.5 meters per second. Which average speed does he have to reach on his second lane to win the bet?

(1.5 + x) / 2 = 2 .... multiply both sides by 2
1.5 + x = 2 * 2
1.5 + x = 4
x = 4 - 1.5
x = 2.5 meters per second

Does it lie inside, outside, or on the circle?​
FrozenT [24]

Answer:

<u>Given circle:</u>

  • (x - 4)² + y² = 25

The center is at (4, 0) and the radius is 5 units

<u>Lets find the distance from (7, 2) to the center of the circle:</u>

  • <u />d = \sqrt{(7 - 4)^2 + (2 - 0)^2}  = \sqrt{9+4} = \sqrt{13} < 5

Since d < 5, the point (7, 2) lies <u>inside</u> the circle

A 15 foot ladder is leaning against a wall. if the top slips down the wall at a rate of 4 ft/s, how fast will the foot be moving
hoa [83]
<span>From the pythagorean theorem, we know that x^2 and y^2 = 15^2, where x and y, where x is the base moving from the wall and y is the distance of the ladder sliding down. This means that y = sqrt(225 - x^2). Plugging in x = 13 gives us y = 2sqrt(14). Differentiating both sides of the original equations gives us dy/dt = 13 x 4 / 2sqrt(14) = 52/2sqrt(14) = 26/sqrt(14) ft/s.</span>

Describe and correct the error in solving the equation.
Nadusha1986 [10]
The error is that 15 was subtracted on the left side when it should’ve been added.
Corrected equation:
27 = n-15
Add 15 to both sides
42 = n

Answer:

82.5

Step-by-step explanation:

Step 1: We make the assumption that 200 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 % = 200.

Step 4: In the same vein, x % = 165 .

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

100 % = 200(1).

x % = 165(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100 % / x % = 200/165

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

x/100 = 165/200

x = 82.5 %
