Answer:
They altogether got £15.75
Step-by-step explanation:
Mark=4
Henry=3
Total ratio= 4+3= 7
Mark's share=4/7
Henry's share=3/7
If Mark's 4= £9
then the total 7 = ( 7 *9)/4 = 15.75
They altogether got £15.75
Answer:
x³ - 5x² + 9x - 5
Step-by-step explanation:
If one root is 2 + i, other has to be 2 - i.
So at least 3 roots, minimum degree is 3
(x - 2 - i)(x - 2 + i)(x - 1)
[(x - 2)² - (i)²](x - 1)
(x² - 4x + 4 + 1)(x - 1)
(x² - 4x + 5)(x - 1)
x³ - 4x² + 5x - x² + 4x - 5
x³ - 5x² + 9x - 5
Answer:
4 ^ 19
Step-by-step explanation:
When we divide exponential expressions, if the bases is the same, we subtract the exponents
x^a/ x^b = x^(a-b)
4^11/4^-8 = 4^(11- -8) = 4^(11+8) = 4^(19)
Answer:
410 kilograms
Step-by-step explanation:
The mean is another way to say average.
Add the weights of all the polar bears together
3,280 kilograms total.
Then divide by the total number of bears
