Some friends went to lunch and split the bill equally. If each person paid $6.75, how many people went to lunch thinking. Use a diagram or equation to explain your thinking. The total is 27$. 27 divided by 6.75 is 4. Suppose
Answer:
4
Step-by-step explanation:
It works with the second one
Answer: 1/6
Explanation: Since we need to draw three cards from a pack of 9 and the digits require an order, then our sample space becomes: 9P3.
Now, we don't care about picking an order when picking three cards to analyse, as there is only 1 way in arranging the three cards in descending order.
Thus, we get:
Answer: x = 92, y = -119
Step-by-step explanation:
Opposite sides of a parallelogram are equal.
x + 6 = 98
x = 92
127 = -y + 8
-y = 119
y = -119
Answer:
96feet
Step-by-step explanation:
Given the height, in inches, of a spray of water is given by the equation ℎ(x)=160−16x^2
x is the number of feet away from the sprinkler head the spray
To get the height of the spray 2 feet away from the sprinkler head, we will simply substitute x =2 into the function and et the height h as shown;
From the equation
ℎ(x)=160−16x^2
h(2) = 160-16(2)²
h(2) = 160-16(4)
h(2) = 160-64
h(2) = 96feet
Hence the height will be 96feet if the spray is 2feet away from the sprinklers head
