Recall that using the pythaogorean theorem, which is only for right-triangles, the longest leg squared is the sum of the other two squared, namely c² = a² + b², now, if those units above are of a right triangle, then 25² = 7² + 24².
do they check out? if they do, then yes, you can make a right-triangle, if not, they nope.
If 50 jackes have been sold in February and the team will get bonus by selling 30% more jackets in March, then they'll need to sell:
30% * 50 =
= 30/100 * 50 =
= 3/10 * 50 =
= 3 * 5 =
= 15 [more jackets]
So they'll get the bonus after selling 50 + 15 = 65 jackets.
Answer:
The number of nickels is 17 and number of dimes is 8.
Step-by-step explanation:
Let the number of nickels be x and number of dimes be y.
Total number of coins is 25.
.... (1)
.... (2)
On solving (1) and (2), we get
Put this value in equation 1.
Therefore the number of nickels is 17 and number of dimes is 8.
Answer:
7. Mean = 48
Median = 47.5
Mode = 72
Range = 66
8. Mean= 59.625
Median = 61
Mode = 90
Range = 79
9. Mean = 31.57
Median = 32
Mode = 46
Range = 34
10. Mean = 42.11
Median = 36
Mode = 51
Range = 51
Step-by-step explanation:
Mean is the average. Mode is the number that appears the most. Median is the middle number. Range is the biggest number minus the smallest number.
Hope this helps.
The answer is: [C]: " (x - 4) " .
