Answer:
yes
Step-by-step explanation:
The height that would be allowed with a ramp 43.5 feet long is ...
h = (43.5 ft)·sin(4.8°) ≈ 3.64 ft
The proposed height is less than 3.64 ft, so the ramp angle is less than 4.8°.
__
The ramp angle is actually arcsin(3/43.5) ≈ 3.95°, which is less than 4.8°.
Answer:
y = 3
Step-by-step explanation:
Subtract 11 from both sides to get:
2y = 6
Then divide both sides by 2 to isolate y:
y = 3
Answer:
-7
Step-by-step explanation:
Lets assume the number Peggy is thinking of be "x".
Now as given, when twice the number is added to three times one more than the number. We can write it as
∴
--- Equation 1
Again, it is given that Peggy gets the same result as when she multiplies four times one less than the number.
∴
-- equation 2
Next, we can equate both the equation 1 and 2 as it is given that result is same.

Let´s distribute 3 into
and 4 into 
⇒ 
⇒ 
Subtract both side by 4x and 3
∴ 
∴ Peggy was thinking of -7
It should be 715, i don’t understand why that isn’t one of the choices.
you’re supposed to multiply everything
