Answer:
The volume of the square pyramid is
Step-by-step explanation:
The volume of the pyramid is equal to
where
B is the area of the base of the pyramid
H is the height of the pyramid
In this problem we have
<em>Find the area of the base B</em>
----> is the area of a square
substitute the values and find the volume
Answer:
2x + 1y =< 300
x + y =>150 units
y <= 2x
Step-by-step explanation:
Let x and y be the numbers of corndogs and shakes that will be sold.
<u>1.</u> The total cost of making these items is given by the sum of:
(x)(RM2) + (y)(RM1)
A total of RM300 is allocated for the cost of these items, so:
2x + 1y =< 300 [Units are RM)
<u>2.</u> Sales are expected to exceed 150 units, in total. This means:
x + y =>150 units
<u>3.</u> Sales for the shakes is less than 2 times that of the corndogs:
y <= 2x
2 root (x-5)=2
Divide each side by 2 (in order to isolate the square root):
Root (x-5) =1
Square both sides to remove the radical sign:
(x-5)=1
Solve:
x=6
To be sure that it is not an extraneous solution, check the solution by replacing the value for the variable in the equation.
2 root (6-5) = 2
The square root of 1 is 1.
2(1)=2
This is correct.
Answer:
D. The clinic opened at 7:30 A.M. and closed at 6:30 P.M.
Step-by-step explanation:
Pay attention to the times, and the amount of time the given location is open.
Only option D makes sense since the clinic open for 11 hours and the difference from the times given is exactly 11 hours; the other options are off, some give longer, and some give fewer amount of time.
8*5=40
8*5=40
12*5=60
12*5=60
12*8=96
12*8=96
Now add the products up.
80+120+96+96
392 is the answer. Hope this helps. (it is C.)
