Well, when you get the answer to a multiplication problem, you divide your answer to check it, so just do that with the decimals that you multiplied.
For Example:
2 x 3 = 6
6 is your answer, so, do this problem to check it:
6 / 3 = 2
Answer:
V = 10,240mm^3
Step-by-step explanation:
The volume of pyramid is given by the following formula:
(1)
b: base of the pyramid = (32mm)^2
h: height
Thus, it is necessary to find the value of h, by using the Pitagoras's theorem, one half of the base and the slant height (which forms a rectangle triangle with h):
by replacing in (1) you obtain:
hence, the volume is 10240mm^3
Answer:
C. 4000
Step-by-step explanation:
let the number of females be : x
number of males be: 10000-x
(10000-x)*105/100 + x*106/100 =10540
10000*105/100 - 105x/100 + 106x/100 =10540
100*105 + x/100 =10540
x/100 =10540-10500
x =40*100
x =4000
Hope this helps!
Answer: A.Samuel: 2.7, 2.7, 2.7, 2.8
Step-by-step explanation:
Given that actual length = 3.2cm
Samuel's score is precise but inaccurate. This is because, each of Samuel's four measurements are close to each other even though it lacks accuracy, because it is a bit far from the actual value of the measurement. Hence, of the measurements given for each of Samuel, Nikita, Jose and Anne, Samuel's score exhibits precision but inaccurate. Nikita's score is both precise and accurate
Answer:
2 cm = 21 km
Step-by-step explanation:
2 cm = 21 km
This is why
3cm = 31.5 km
3/3 = 31.5/3 (To find out how much 1 cm is equal to)
1 cm = 10.5 km
And since 1 cm = 10.5 km is not there in the options... I tried to find out for 2 cm
So, I multiplied both sides by 2
1 cm = 10.5 km
1 *2 = 10.5 *2
So the answer become 2 cm = 21 km
