Answer:
Hypotenuse is 13 ft.
Step-by-step explanation:
A=(1/2)bh
30=(1/2)(5)(h)
30=2.5h
h=12 so ZY = 12ft
Then
Answer:
4x-20
Step-by-step explanation:
you put the x's together and since its negative,you can make it -20 instead of +-20
Answer:
c. 59.3 ft²
Step-by-step explanation:
½× [(3.14×5²) + (10×4)]
= ½ × (78.5+40)
= ½× 118.5
= 59.3
Answer:
C
Step-by-step explanation:
Multiples of 4: 4,8,16,20,24,28,32,36,40,44,48,52,56,60
Multiples of 15: 15,30,45,60
Th smallest number that they both can multiply to is 60
Answer:
C)
Step-by-step explanation:
Note that one of the lines is simply y=-1 for any x, so we can dismiss the only answer without y=-1. That rejected answer is A)
Now let's notice, that the other line is decreasing y when increasing x. That tells us that in the equation y = ax + b, a has to be negative. This brings us to reject option D).
What is the y of that line for x = 0? Because y = ax + b, for x = 0 we will get the value of b. This is called the intercept. The line is at y=4 for x=0, so we know that the b in the equation must be positive 4. This fits answer C, but rejects answer B). And so, we have found that C) is the only possible answer.
