Answer: 316.52
Step-by-step explanation:
77.2*4.1 = 316.52
If you have problems with multiplying decimals:
Multiply the numbers just as if they were whole numbers.
1.Line up the numbers on the right - do not align the decimal points.
2.Starting on the right, multiply each digit in the top number by each digit in the bottom number, just as with whole numbers.
3.Add the products.

Answer:
15..
Step-by-step explanation:
4, 10, 14, 18, 22, 22
Mean = (4 + 10 + 14 + 18 + 22 + 22)/6
= 90/6
= 15.
Number to be added, 'y'
For the mean to be the same
(90 + y) / 7 = 15
90 + y = 15 × 7
90 + y = 105
y = 105 - 90
= 15
For the fulcrum to balance, the product of weight and distance on both sides of the fulcrum must be the same.
Let d1= x. since total distance is 12, we can write d2 = 12 - x
for the fulcrum to balance:
60x = 50(12 - x)
60x = 600 - 50x
110x = 600
x = 5.45
Thus, d1= 5.45
and
d2= 12 - d1 = 12 - 5.45 = 6.55
d1 = 5.45
d2 = 6.55
Answer: 5:4
Step-by-step explanation:
Given : The number of convertibles = 1960
The number of minivans = 490
Total cars = 2450
The ratio of A to B can also be written as 
.
The ratio of cars to convertibles = 
![=\dfrac{2450}{1960}\\\\=\dfrac{5}{4}\ \ \ \text{[Simplest form]}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B2450%7D%7B1960%7D%5C%5C%5C%5C%3D%5Cdfrac%7B5%7D%7B4%7D%5C%20%5C%20%5C%20%5Ctext%7B%5BSimplest%20form%5D%7D)
Hence, the ratio of cars to convertibles = 5:4
