Answer:
8 girls
Step-by-step explanation:
8 girls If there are 20 children and for every 3 boys there is 2 girls that's 5 children. 5x4 = 20 so in every 5 kids there is 2 girls. So then do 4x2 = 8
Answer:
10⁴
Step-by-step explanation:
10 is repeated 4 times, so your exponent would be 4 with a base of 10.
The answer is $654.06.
5.5% of $575 is $31.63. 575 x 0.055 = 31.63
This means that in one year he earns $31.63. In two years it will be $63.25 (31.63 x 2 = 63.25)
Then in half a year it will be $15.81 (31.63/2 = 15.81)
Finally add 15.81 and 63.25 to get $79.06 which you then add to the initial $575 to get the total amount earned in 2 1/2 years which is $654.06.
Answer:
Step-by-step explanation:
The relevant relation is that the product of distances from the point of intersection of secants to the two points of intersection of each with the circle is a constant. The point of tangency counts as both points of intersection.
__
By way of example, the product of distances to the circle for the tangent segment is 10·10 = 100
This is also the product of the distances on the secant that intersects the tangent:
100 = 5(5+x+9)
20 = x +14 . . . . . divide by 5
x = 6 . . . . . . . . . . subtract 14
__
The same is true when the secants intersect <em>inside</em> the circle:
6·9 = y·3
y = 18 . . . . . . divide by 3
