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

Answer:
If the number of blue tiles in the bag is 180, then the probability of randomly drawing a red tile equal to 1/10.
Step-by-step explanation:
Total number of red tiles in a bag = 20
Let us assume the number of blue tiles in a bag = p
So, the total number of tiles in a bag = Red Tiles + Blue tiles
= 20 + p
Now, let us find the probability of drawing a red tile:
But, here the probability of drawing a red tile = 1/10
or, p = 180
Hence, if the number of blue tiles in the bag = 180, then the P Picking out a red tile ) is 1/10.
Answer:
x < 12
Step-by-step explanation:
So 8 times the sum of a number and 26 is less than 304. To find the number, lets write a equation where the "number" is x.
8 times the sum of a number and 26 can be written as 8 * x+26, however since the sum of x and 26 are being multiplied, we write this as 8(x+26). Since 8 times the sum of a number and 26 is less than 304, we set 8(x+26) to < 304. This gives us our equation:
8(x+26) < 304
Lets start to solve for x by dividing by 8, giving us:
x+26 < 38
Now lets isolate x by subtracting 26 from both sides, which gives us our answer:
x < 12
So x is less than 12.
Hope this helps!
