Answer:
Not sure if this is correct but it should be y=210x-140
Step-by-step explanation:
Answer: 1. Correct, 2. Incorrect 90° angle not 80° angle answer is 50, 3. Is correct, 4. Is correct
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Using the pythagorean theorem, we can determine if these are right triangles or not.
equation: sqrt a^2+b^2=c
this means the square root of the two shortest sides squared must equal to the largest side, (the hypotenuese).
Work for C:
Squareroot of 32^2 + 24^2 = 40cm
Answer:
(a) , , , , , , .
(b) , , , , , , , .
Step-by-step explanation:
In this exercise we only need to recall the formula for C(n,k):
where the symbol is the factorial and means
.
By convention 0!=1. The most important property of the factorial is , for example 3!=1*2*3=6.
(a) The explanations to the solutions is just the calculations.
- .
(b) The explanations to the solutions is just the calculations.
For all the calculations just recall that 4! =24 and 5!=120.
476miles per 14gallons of gas
is the same as 476 / 14 = 34
so 34miles / 1gallon of gas.
34x =578 where x is the number of gallons
578 / 34 = 17gallons
