Answer:
Step-by-step explanation:
8x5 = 40
Because you just go up by fives like 5 10 15 20 25 30 35 40 and so on
4.8 he is 4.8 miles into the path
Yess, such fun so
q=number of quarter
n=number of nickles
q+n=63
9.15=915 cents
25 cents=1 q
5 cents=1 n so
915=25q+5n
915=5(5q+n)
divide by 5
183=5q+n
we also have q+n=63
subtract q from both sides
n=63-q
subsitute 63-q for n in second equation
183=5q+63-q
add like terms
183=4q+63
subtract 63 from both sides
120=4q
divdie by 4
30=q
there were 30 quarters
subsitute
63=30+n
subtract 30
33=n
30 quarters
33 nicles
Answer:
5
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile.
First find the median.
The median is the middle value of the data set arranged in ascending order
1 5 5 7 9 ← data in ascending order
↑ median
The lower quartile is the middle value of the data to the left of the median. If there is not an exact middle then it the average of the values on either side of the middle.
1 5
↑ lower quartile = = 3
The upper quartile is the middle value of the data to the right of the median.
7 9
↑ upper quartile = = 8
Thus
interquartile range = 8 - 3 = 5
(3x - 10) + 45 + (2x + 10) = 180 (the sum of the angles is 180)
3x - 10 + 45 + 2x + 10 = 180
3x + 2x = 180 + 10 - 45 -10
5x = 135
x = 27
3(27) - 10 = 71 (first angle)
2(27) + 10 = 64 (second)
45 (third)
71 + 64 + 45 = 180
