Answer:
63m
Explanation:
We are given the following in the question:
Average speed of swimming = 45 m/min
Time = 1 minute 24 seconds
Converting time into minutes:
1 + 24/60 = 1.4 minutes
Distance: 45 × 1.4 = 63m
Answer:
x = 20
Step-by-step explanation:
Use Pythagorean Theorem to solve for x:
a^2 + b^2 = c^2
Plug in given values if a = 12, b = 16, and c = x (x is hypotenuse)
12^2 + 16^2 = x^2
(12*12) + (16*16) = x^2
144 + 256 = x^2
400 = x^2
Take square root of both sides to solve for x
sqrt(400) = sqrt(x^2)
20 = x or x = 20
The mean is where you add all the numbers up then divide by the amount of numbers there are so 6 that will give you the mean
The mode is the most occurring number
Put all the numbers in order from smallest to largest the median would be the middle number
D = c - 3 Because Denise scored three fewer points than Carter, his score equals Carter's score minus 3. d = 21 - 3 Now, let's substitute in the answer we got for Carter's score. d = 18 Yep! The question says that Denise scored 18 points, so the answer we got is correct.

Answer: 5.5 which is choice B</h3>
Have a look at the diagram I posted below. I marked on your image to add in another angle. This angle is also 20 degrees because of congruent alternate interior angles (horizontal lines are parallel). This angle I add in is the reference angle of the triangle
opposite the reference angle is the vertical side x
adjacent to the reference angle is the horizontal side 15
We'll use the tangent rule. Make sure your calculator is in degree mode.
tan(angle) = opposite/adjacent
tan(20) = x/15
15*tan(20) = x <<-- multiply both sides by 15
x = 15*tan(20)
x = 5.45955 <<--- use calculator; this is approximate
x = 5.5 <<--- round to one decimal place
