We have 11 as our base value, meaning that we add 11 to something, so we have 11+<something>. To find that something, we want to know how long it takes to go 21.78 miles at 33 miles per hour. To get this, we want to turn miles per hour into minutes per mile and multiply that by 21.78 miles to get our answer. Therefore, we cross them out as shown in the equation to get
Answer:
8s + 12
s=12-8
s=4
or
8s +12
s=12+8
s=20
Step-by-step explanation:
im not sure kung minus o plus kasi kung kinus mababa lang binayad nya
Answer:
,, assuming the true mean temperature 62 degrees Fahrenheit there is a 0.1% probability that the null hypothesis is true by chance alone
Enlarging the radius of the ice cream cone will result in a volume that is larger by twice the amount of the scale on the radius. For instance, doubling the radius will make the volume 4 times larger.
Enlarging the height of the ice cream cone will result in a volume that is larger by the same amount as the scale on the height. For instance, doubling the height will make the volume 2 times larger.
Going from these answers, the price will change in the same manner as the volume changes. A doubled volume would be a doubled price; a volume 4 times as large will result in a price 4 times as much.
The volume of a cone is given by the formula
V=(1/3)πr²h
If we double the radius, we then have
V=(1/3)π(2r)²h = (1/3)π(4r²)h = 4(1/3)πr²h.
Doubling the height instead will give us:
V=(1/3)πr²(2h) = 2(1/3)πr²h
