Answer:
A = 2.63
B = 2
Step-by-step explanation:
To find the population density, what we need to do simply is divide the population by the area of the UK
mathematically, that would be;
(6.41 * 10^7)/243,610 = 263.125
To the nearest whole person= 263 people/ square meter
So now we want to write 263 in standard form = 2.63 * 10^2
So this means A = 2.63 and B = 2
Answer:
There are 19 big marbles
Step-by-step explanation:
10a + 3b = 209
a = 3b
3b = 3b
10a + a = 209
11a = 209
a = 209/11
a = 19
Answer:
For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6
To find the number of miles Erma can drive, you will write and equation and solve it to find the amount of miles that can be driven on $600 over the 1600 miles that are allowed.
Daily rate + cost per mile over 1600 = total cost
(65 x 8) + 0.24m = 600
520 + 0.24m = 600
-520 -520
<u>0.24m </u>= <u>80</u>
0.24 0.24
m = 333.33... miles
The maximum number of whole miles she can drive would be 1933 miles (1600 + 333).
