<h2>X = 20</h2><h3></h3><h3>10/16</h3><h3>is the same as</h3><h3>12.5/20</h3><h3></h3><h3><em>Please let me know if I am wrong.</em></h3>
Answer:
Step-by-step explanation:
Your first job is to make the bases the same. Once you have done that, you can equate the powers.
(1/27) ^ (1 /- 3) = 3
(1/27)^(1/-3)(24)
3^24 = 3^(7 - 2x)
24 = 7 - 2x Subtract 7 from both sides
17 = -2x Divide by -2
-8.5 = x
Answer:
6852 feet .
Step-by-step explanation:
Refer the attached figure
The chairlift at a ski resort rises a total of 2600 feet from where it starts. i.e.AB = 2600 feet
The angle of elevation is about 22.3 degrees.i.e.∠ACB= 22.3°
We are supposed to find How far do riders travel on the lift i.e.AC
In ΔABC
We will use trigonometric ratio
So, riders travel 6852 feet .
Anzelm wants to burn 540 calories while jogging. Jogging burns about 12 calories per minute.
he usually plans to stop and rest for about 5 minutes.
m represents the total minutes.
12 calories per minute.
for m minutes the calories burn is 12m
He stop and rest for about 5 minutes. so we need to subtract 5 from total minutes
So expression becomes 12(m-5)
He wants to burn 540 calories. So we set the calories = 540
The equation becomes ,
12(m-5) = 540
Now we solve for m , total number of minutes
12(m-5) = 540(divide by 12 on both sides)
m - 5 = 45
m = 50 ( add 5 on both sides)
Anzelm should plan to be out jogging for 50 minutes
