Answer:
It will take them 5 hours to make 180 cupcakes
Step-by-step explanation:
17 + 19 = 36 x 5 = 180
Answer
14 degrees
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Add the number of decimal places of the two numbers being multiplied to know the number of decimal places of the product.
A: 3.48 x 42.37 = 147.4476
2 decimal places + 2 decimal places = 4 decimal places
Only choice A is correct.
Answer:
The cost of wasted nitric acid is $187.02
Step-by-step explanation:
Since it is given that specific gravity of Nitric Acid is 1.42 Thus the density of nitric acid is
Now from the basic relation of mass volume and density we have
Since the mass of the nitric acid is given to be 5.112 kg = 5112 grams
Thus the volume of nitric acid is
Now we know that 1000 cubic centimeters euals 1 litrer
Thus the calculated volume in liters is
Thus the cost of acid spilled equals
For this case what you must do is find the diagonal of the square to find the diameter of the circle and then be able to obtain the radius.
We have then:
A = L ^ 2 = 128
L = root (128)
L = 11.3137085
Then, the diagonal of the square knowing its sides is:
d = root ((L) ^ 2 + (L) ^ 2)
d = root ((11.3137085) ^ 2 + (11.3137085) ^ 2)
d = 16 feet
Finally the radius of the circle is:
r = d / 2
r = (16) / 2
r = 8feet
answer:
the radius of the circle is
r = 8feet
