B.
The Probability of choosing a girl is 17/30.
The probability of choosing an A student is 5/30
<span>The P(girl) + the P(A student) = 17/30 + 5/30 = 22/30 = 11/15.</span>
So let's say that the first number is xxxxx and the second one is yyyyy.
The value of 7 in the first should be 1000 times bigger than in the second, so let's make it 7000 and 7:
z7xxx and yyyy7
now, the value of 3 in the first number is 100 times the value of the 3 in the second number
let's make it 37xxx - then the value of 3 is 30 000 so in the second number it must be 300,
then we have 37xxx and yy3y7
let's substitute the ys and xs by 0:
37000 and 307 - that's the solution!
Answer:
1: ?= 52.5
2. ?= 17.1428571429
Step-by-step explanation:
The proportions are 3.5x difference
10-2/3=9 1/3 if you estimate that it would be 9
next it is 3 - 1/8= 2 7/8 estimate it would be 3
so 9 x 3= 27
Answer:
191 grams
Step-by-step explanation:
12.4×5.6×2.5=173.6
7.9×173.6=1371.44
9.0×173.6=1562.4
1562.4-1371.44=191
