Dan : 0.14 Gallons
Mike: 0.5 Gallons
Answer: Amy
Step-by-step explanation:
Look closely
Sin(225)
225 degrees is in the 3rd quadrant. And in the third quadrant only tangent is positive, sin is negative.
For third quadrant, basic angle = 225 - 180 = 45
sin225 = - sin45
sin225 = - sin45 = -0.7071
sin 225° ≈ -0.7071
I am not really sure could you give me a formula
<h3>
Answer: Choice B) -t+7</h3>
Explanation
The like terms are ones that have the same variable in them, or that dont have a variable at all attached. One pair of like terms is t and -2t, which combine to t+(-2t) = t-2t = -t
The other pair of like terms are 4 and 3 which add to 7
So t+4+3-2t simplifies fully to -t+7, which is the same as 7+(-t) = 7-t
We cannot simplify any further from here as the 7 and -t are not like terms.
Answer:
h = 80
Step-by-step explanation:
Remark
The general Volume formula for a pyramid is V = 1/3 * B * h
Givens
base edge = 3 m
V = 240 m^2
Solution
V = 1/3 * B * h
B = s^2
B = base edge^2
B = 3^2
B = 9
240 = 1/3 * 9 * h multiply by 3
240 * 3 = 9 h Divide by 9
80 = h
