I do A and B but that is the way I learned it. Hope this helps :)
X is between 80 and 90, if the square root of a number (x) is 9, you would do 9x9 to solve for x, x=81
Answer:
2.5, 21/8, ³√25, π, √19
Step-by-step explanation:
The following data were obtained from the question:
³√25, π, 21/8, 2.5, √19
Next, we shall express each data as a decimal number where necessary. This can be obtained as follow:
³√25 = 2.9
π = 3.14
21/8 = 2.6
2.5 = 2.5
√19 = 4.4
Finally, we shall order the expression from least to greatest. This is illustrated below:
2.5, 21/8, ³√25, π, √19
Let h be hot dogs and s be sodas
h+s=221
h=s-59
s=s
s+s-59=221
2s-59=-221
2s=280
s=140
h=140-59=81
140+81=221
Answer: there were 81 hotdogs and 140 sodas sold
The scientist was 83.5 feet below sea level while studying ocean life.
Given that:-
Distance the scientist ascended after studying the ocean life = 61.9 feet
Distance below sea level the scientist is after ascending = 21.6 feet
We have to find the distance by which the scientist was below sea level while studying the ocean life.
We know that,
Distance by which the scientist was below sea level while studying the ocean life = Distance the scientist ascended after studying the ocean life + Distance below sea level the scientist is after ascending
Hence, we can write,
Distance by which the scientist was below sea level while studying the ocean life = 61.9 + 21.6 = 83.5 feet.
