Answer:
Step-by-step explanation:
Smaller perfect squares near 99 is 81
Larger perfect square near 99 is 100
First step would be to find the two perfect squares that lies between on the number line. I could then think about the number 99 and how close it is to the smaller perfect square and the larger perfect square. That could tell me how far above or below the of the two perfect squares 99 lies on the number line. I could then take the square root of the perfect squares to see how I would estimate the square root of 99. The √99 is almost 10.
81 < 99 < 100
√81 < √99 < √100
8 < √99 < 10
So, √99 is almost 10.
Answer:
38 or 38.33 cups of water.
Step-by-step explanation:
You need 5 cups of water for every 3 ounces of medication. We can set up a proportion: #oz of medication/#cups of water= #oz of medication/# cups of water. We can plug in some numbers from the problem.
3/5=23/n. You can use any variable, but I'm using n for how many cups of water Jim will need for 23 ounces of medication.
We can cross multiply: 3*n=5*23.
3n=115
We divide both sides by 3.
n=38.3333333.......
Rounding to the nearest whole number, Jim will need 38 cups of water, or 38.33 cups if you're rounding to the nearest hundredth.
Hope this helps :)
Answer:
Step-by-step explanation:
Volume of the cube = s^3
s = 9cm
V = 9 * 9 * 9
V = 729 cm^3
d = mass / volume
d = 3645 / 729
d = 5 grams / cm^3
Total = 14
jhon = 2 / 14 * 20 = 2.8
mina = 5 / 14 * 20 = 7.1
tim = 7 / 14 * 20 = 10
since sweet can't be divided in decimal places so it will be 3, 7, 10
