Which equation could be used to find the value of x?
Triangle DEF where angle E is a right angle. DE measures 55. EF measures x. Angle D measures 49 degrees.
cos 49° = x over 55
tan 49° = x over 55
cos 49° = 55 over x
tan 49° = 55 over x
Answers
The answer is tan 49° = x over 55 (I got it correct on my quiz).

after how many seconds is needed for a thrown ball to reach a 14-m distance if it's distance is given by the relation d=10+40t-5t? (t=time in seconds)
Answers
Answer:
Time, t = 0.1143 seconds.
Step-by-step explanation:
Given that distance, d = 14m
From the equation;
d = 10 + 40t - 5t
d = 10 + 35t
Substituting the value of distance;
14 = 10 + 35t
35t = 14 - 10
35t = 4
t = 4/35
t = 0.1143 seconds.
The time needed for the ball to reach the 14-m distance is 0.1143 seconds.
The thrown ball will reach a 14-m distance after 0.114 seconds.
The relation given is:
d = 10+40t-5t
where, d = 14
In this case, we've to put the value of d into the relation and this will be:
d = 10+40t-5t
14 = 10 + 40t - 5t
Collect like terms
40t - 5t = 14 - 10
35t = 4
Divide both side by 35
35t/35 = 4/35
t = 0.114 seconds.

Tom is 4 more than twice andrews age. Sara is 8 less than 5 times ANdrews age. If tom and sara are twins how old is andrew
Answers
Answer:
there
Step-by-step explanation:
T = 4 + 2A
S = 5A - 8
T = S
Since T and S are equal, set them against each other
2A + 4 = 5A - 8
Subtract 2A from each side, and add 8 to each side
12 = 3A
Divide each side by 3
A = 4
If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.

On a Ferris wheel, Sarah observes that it takes 45 seconds for her chair to complete a full revolution. Her chair is 30 feet from the axle of the Ferris wheel.
To the nearest hundredth, Sarah’s angular velocity is ____ radians per minute
Answers
Answer:
8.38 radians
Step-by-step explanation:
correct on edge 2021
The angular velocity of the Ferris wheel is 8.38 radians/minute.
What is angular velocity?"The angular velocity is the time rate at which an object rotates or revolves about an axis."
It takes 45 seconds for her chair to complete a full revolution.
Therefore, in terms of revolution per minute, the speed is
= 60/45 revolutions/minute
= 4/3 revolutions/minute.
We know, 1 revolutions = 2π radian
Therefore, 4/3 revolutions/minute
= (4/3) × 2π radians/minute
= 8.38 radians/minute
Hence, the angular velocity is 8.38 radians/minute.
