Find a gradient of a line that is parallel and perpendicular to this line with this gradient of 3 1/3

a parallel line has the same gradient, so the gradient would be 3 1/3

a perpendicular line has the negative inverse gradient of the original (eg. if the original gradient is 4/3 then the perpendicular gradient would be -3/4 (all you have to do is change the +/- sign and flip the fraction), so in your case the gradient of the perpendicular line would be -3/10 (since 3 1/3 = 10/3)

a rectangular fish tank 60 centimeters by 15 centimeters by 34 centimeters is 1/3 full of water. find the volume of water needed

son4ous [18]

Answer:

$20,400\ cm^{3}$

Step-by-step explanation:

step 1

Find the volume of the tank

$V=(60)(15)(34)=30,600\ cm^{3}$

step 2

we know that

If the tank is 1/3 full of water

then

the volume of water required to completely fill the tank is equal to 2/3 of the tank capacity

so

$(2/3)30,600=20,400\ cm^{3}$

A golf ball is hit with an initial velocity of 100 feet per second. The height of the golf ball can be represented by the equati

LenaWriter [7]

Answer:

6.25 seconds

Step-by-step explanation:

<u>Using the the equation </u>

h = 100t − 16t^2

<u>The ball hits the ground, when h = 0, solving below equation:</u>

100t − 16t^2 = 0
4t(25 - 4t) = 0
t = 0 seconds, this is the starting point when ball was hit
25 - 4t = 0 ⇒ 4t = 25 ⇒ t= 25/4 = 6.25 seconds later the ball hits the ground

Jake has $4,000 invested at 8% annual interest. He has $2,800 more to invest. At what rate

schepotkina [342]

Step-by-step explanation:

with $4,000 invested, Jake has

8% × $4,000 = $320 annually.

in order to have annual interest $628, he has to get more interest $(628-320) = $308.

the rate should be:

308/2800 × 100%

= 308 /2800 × 100%

= 11%
