Answer:
Step-by-step explanation:
Let the 3 consecutive odd numbers be n, n+2, n+4.
(n+2) + (n+4) = 3n - 9
Collect like terms
n+n-3n=-9-6
-n=-15
n=15,
n+2=17
n+4=19
Answer:
9:16
Step-by-step explanation:
The ratio of sides of the lengths of rectangles is 3:4.
- Now since the scale is constant. So the scale ratio of area will be square of the side ratio .
<u>T</u><u>hat </u><u>is </u><u>:</u><u>-</u><u> </u>
→ Ratio of Area = ( 3 : 4)²
→ Ratio of Area = (3/4)²
→ Ratio of Area = 9/16
→ Ratio of Area = 9:16
<h3>
Hence the ratio of areas is 9:16 .</h3>
Answer:
The second possible answer is the correct one.
Step-by-step explanation:
The second possible answer is the correct one. As x increases, 4^x increases exponentially. However, in this case there's a negative sign in front of 4^x, so we know that the graph follows an exponential trajectory downward. Also note that 4^0 = 1, so 1 - 4^x = 0 at x = 0.
On a cube there are 6 sides. There are three odd numbers and one 4, so the probability of rolling these numbers is 4/6 which is 2/3. To get the probability of it from two rolls, we multiply it by itself once because it is being rolled once more. 2/3 x 2/3 is 4/9, so the probability of rolling an odd number or four in two roles is 4/9.
