The height h of an object projected upward from the floor of the Golden Gate Bridge which has an initial height of 220 feet and

with an initial velocity of 30 feet per second is given by h=-16t^2+30t+220. How many seconds later will the rock hit the water? Round to the nearest tenth. Please help ASAP!!! :(

Step-by-step explanation:

time is distance divided by velocity/speed

t = 220/30

t = 7.33333 = 7.3

Jim had three waffles. He ate 1/6 of one waffle, and. 2/3 of another waffle. How many waffles were left?
Troyanec [42]
So find how much was eaten
1/6 and 2/3=eaten
add 1/6 and 2/3
convert bottom number to same
2/3=4/6
1/6+4/6=5/6
5/6 eaten
3-5/6=
2+1-5/6=
2+6/6-5/6=

X-5y=-15x−5y=−15x, minus, 5, y, equals, minus, 15 Complete the missing value in the solution to the equation. (-5,(−5,left paren
Y_Kistochka [10]

Answer:

<h2>The missing value is 2. The coordinate will be (-5, 2)</h2>

Step-by-step explanation:

The question is not properly written. Find the correct question below.

If x – 5y = -15 . Complete the missing value in the solution to the equation (-5, ____)

Let the coordinate of the variables be (x, y). Comparing the coordinates (x, y) with the given coordinate (-5, __), we will discover that x = -5. To get the y coordinate, we will substitute x = -5 into the given expression as shown;

If x – 5y = -15

-5 - 5y = -15

Adding 5 both sides

-5-5y+5 = -15+5

-5y = -10

Dividing both sides by -5;

-5y/-5 = -10/-5

y = 2

<u>Hence the missing value in the solution of the equation is 2</u>. The coordinate will be (-5, 2)

Example of six ordered pairs with country names alongside their capitals are:

{(England, London), (USA, Washington DC), (India, New Delhi), (Nepal, Kathmandu), (Austria, Vienna), (Albania, Tirana)}.

<h3>What are Ordered Pairs?</h3>
  • Ordered pair can be described as a pair of objects or numbers in a particular order.
  • In an ordered pair, the order of the objects or numbers are very important. For example, (a, b) is not the same as (b, a).

Therefore, example of six ordered pairs with country names alongside their capitals are:

{(England, London), (USA, Washington DC), (India, New Delhi), (Nepal, Kathmandu), (Austria, Vienna), (Albania, Tirana)}.

<span>The first two cuts can intersect at only 1 pt regardless of where they are placed. So 4 pieces there. The last cut can only intersect each other cut a 1 pt, regardless of placement. As long as the intersection is different than the first intersection, then you will have 7 pieces.</span>
