Answer:
<u>9 mph</u>
Step-by-step explanation:
Calvin's first leg of the trip took 0.5 hr (30 minutes) at 6 mph. That means he travelled (0.5hr x 6 mph =) 3 miles. He travelled 3 miles on the return trip, by definition (same path home). At 18 mph, 3 miles would take (3 miles/18 mph =) 0.1667 hours. That makes a total of 6 miles and (0.5 + 0.1667=) 0.6667 hours.
(6 miles)/(0.6667 hours) = 9 mph is Calvin's average speed for the round trip.
62unit/hour is the answer
distance/time
Step-by-step explanation:
domain is the valid interval for the x (input) values for the function.
the range is the valid interval for the y (result) values of the function.
so, we have a function definition and a valid domain interval for x. we therefore try the x values and see what result values they create. and that defines the range.
x = -6
y = 4 - -6 = 4 + 6 = +10
c
x = 2
y = 4 - 2 = +2
x = 7
y = 4 - 7 = -3
we have therefore a range of {-3, 2, 10}
Answer:
The length of the angle bisector of angle ∠A is 6.01.
Step-by-step explanation:
It is given that length of leg AC = 5 ft and the hypotenuse AB = 13 ft.
Using pythagoras theorem
Bisector divides the angle in two equal parts, therefore,
In triangle ACD.
Therefore the length of the angle bisector of angle ∠A is 6.01.
Answer:
A. 1)5.5 2)4.5 3)5.75 4)6.25 B. 1.75 C. A correct B incorrect C incorrect D correct
Step-by-step explanation:
Mean is a fancy way of saying <em><u>Average </u></em>, when calculating average you add all the numbers and divide by how many numbers there are:
<em><u>A</u></em>
<u>1.</u>
8+6+3+5=22/4=5.5
<u>2.</u>
5+7+4+2=18/4=4.5
<u>3.</u>
8+7+5+3=23/4=5.75
<u>4.</u>
6+8+4+5=25/4=6.25
<em><u>B</u></em>
largest mean is 6.25, smallest mean is 4.5:
<u>Subtract lowest mean from highest mean:</u>
6.25-4.5=1.75
<em><u>C</u></em>
<u>A)</u>
this is correct because averaging your average gives an overall average,
<u>B)</u>
if a is correct b has to be incorrect
<u>C)</u>
if D is correct C must be incorrect
<u>D)</u>
The closer they are together, that means more likely to be accurate because they are almost the same
I hope this helps u!
pls pls PLS give a brainliest and a thx ;)
