Answer:
24
Step-by-step explanation:
30%+40%=70%
100%-70%= 30%
what's 30% of 80?
80×0.3= 24
Answer:
A right prism is a prism that has its bases perpendicular to its lateral surfaces.
When we cut a prism parallel to the base we get a cross section of a prism. The cross section is congruent (same size and shape) as the base, as can be seen in the following diagram.
Answer:
Step-by-step explanation:
olve the line equation for y
:
y = -ax/2 +5
:
therefore, the y-axis intercept is 5
:
area of triangle = (1/2) * base * height
:
(1/2) * base * 5 = 10
:
base = 4 which is the x-axis intercept
:
-a(4)/2 +5 = 0
:
-2a = -5
:
a = 5/2
:
A polynomial with solution must be a multiple of . So, your polynomial must be a multiple of
But this is already a cubic polynomial, so it can only be a multiple in a numerical sense:
The coefficient can be found imposing the condition about the y-intercept. The y-intercept is nothing more than the polynomial evaluated at zero:
And we want this to be -12, so we have
So, your polynomial is
And if you expand it it becomes
9514 1404 393
Answer:
(b) The slope of the line for Restaurant B is 2 times greater than the slope of the line for Restaurant A.
Step-by-step explanation:
The slope of the relation for Restaurant A is ...
y/x = 1/10
The slope of the relation for Restaurant B is ...
y/x = 5/25 = 1/5 = 2×1/10
The slope of the line for Restaurant B is 2 times as great as the slope of the line for Restaurant A.
