Answer:
Third side must be greater than 7 and less than 17
Step-by-step explanation:
If a triangle has two sides of lengths 5 and 12, the value for the length of the third side be greater than 7 and less than 17.
C is Celia's calorie count and R is Ryan's. d = days
C = 1200 + 100d
R = 3230 - 190d
Since you want to find when they will consume the <em>same</em> amount of calories, you set the two equations equal to each other: 1200 + 100d = 3230 - 190d.
Then, subtract 1200 from both sides: 100d = 2030 - 190d. Next, add 190d to both sides: 290d = 2030. Therefore, the number of days is eqal to 2030/290, which is 7.
Yes I got the third one too
Answer:
10
Step-by-step explanation:
nCr = 5!/(3! × (5 - 3)!)
= 10
123/ 124/ 125/ 134/ 135/ 145/ 234/ 235/ 245/ 345
The formula for combinations is generally n! / (r! (n -- r)!), where n is the total number of possibilities to start and r is the number of selections made. In our example, we have 52 cards; therefore, n = 52.
The line passes through points (0,0) and (7,4)
Gradient = (y2-y1)/(x2-x1) = (4-0)/(7-0) = 4/7
