Answer:
Step-by-step explanation:
we know that
The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
In this problem
The tangent of angle of 5 degrees is equal to the quotient of "rise over run"
Let
y ----> the rise of the ramp
x ----> the run of the ramp
we have
substitute and solve for x
Answer:
$9.00
Step-by-step explanation:
Given that $1.8 is 20% of the breakfast cost.
-We can use proportions to find the 100% cost of the breakfast before the tip.
-Let x be the full breakfast cost:
Hence, the full breakfast cost is $9.00 before the tip.
Answer:
30
Step-by-step explanation:
5(z+4)+5(2-z) (expand parentheses by distribution)
= z(5) + 4(5) + 2(5) -z(5)
= 5z + 20 + 10 -5z
= 30
Answer: The answer is 2.
Step-by-step explanation: If you have 2 minuses together, then that actually means a plus. -7+9 is 2.
