Answer:
x=1,-5x=1,−5
Step-by-step explanation:
0=(x−1)(x+5)
2 Switch sides.
(x-1)(x+5)=0(x−1)(x+5)=0
3 Solve for xx.
x=1,-5x=1,−5
To answer this you have to use Pythagoras's theorem: a^2 + b^2 = c^2
Put in the values:
5^2 + 15^2 = c^2
Simplify it:
25 + 225 = c^2
Simplify again:
250 = c^2
Square root both sides:
15.8113883008 = c
So the ramp is:
15.8113883008 feet
Now round the number:
15.8ft
The above is the answer :)
(btw sorry in advance if you've spotted a mistake)
Answer:
B 17.5 ft
Step-by-step explanation:
tangent = opposite / adjacent
tan 35° = h / 25
multiply both sides by 25
h = 25 (tan 35°)
tan 35° = 0.70 (from your calculator)
h = 25 (0.70)
h = 17.51 ft.
Answer:
(A)48
(B)volume of one of the small cubes is 1/64cm^3
c)3/4x1x1=3/4cm^3
Step-by-step explanation:
Answer:
? = h
Step-by-step explanation:
v = lwh
v / wh = lwh / wh
v / wh = l
