3, 4, 5, or 6 inches? Help plz
Answer:
3 inches
Step-by-step explanation:
25*20*h=750
500h=750
h=1.5
Height*2 = length of one of the cut corners
1.5*2=3
Therefore, 3 inches
Answer:
5 in
Step-by-step explanation:
x = number of in cut from each side
V = 750
V=lwh
l = 25 -2x
w = 20-2x
h =x
V = (25-2x)(20-2x)x
(25-2x)(20-2x)x = 750

3x^2 - 6 = 2x wat is discriminant of the quadratic equation
Answer:
The discriminant is 76
Step-by-step explanation:
The equation needs to be in the form

Solve the system by substitution. If the system is inconsistent or has dependent equations, say so.
-X-5y = -6
y = 6x-5
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
• A. The system has a single solution. The solution set is O. (Type an ordered pair.)
B. There are infinitely many solutions and the equations are dependent. The solution set is {(x,y)} (Type an ordered pair.)
C. The system is inconsistent. The solution set is the empty set
Answer:
The (single) solution is (1, 1).
Step-by-step explanation:
The second equation tells us that y = 6x-5. Substitute this 6x - 5 into the first equation, as follows: -x - 5(6x - 5) = -6
Then -x - 30x + 25 = -6. Combining like terms, we get -31x = -31, so that x = 1. Subbing this result into the second equation, we find y: y = 6(1) - 5 = 1. The solution is (1, 1).

The solid which is a triangular pyramid is A pyramid with triangular base.
What is a Pyramid?A pyramid is a three dimensional solid shape which has a flat base which is polygonal in shape and it has a triangular flat lateral faces, which joins at a point called vertex.
There are many kinds of pyramids like triangular pyramid, square pyramid, right pyramid etc.
Triangular pyramid has the base of the pyramid in triang7ular shape.
So there will be three lateral triangular faces where each of them has one side on the base.
So a triangular pyramid has a triangular base.

clock lost 1 minute and 18 seconds in 39 days. How many seconds did it lose per day?
Answer:
2 seconds
Step-by-step explanation:
1 minute 18 seconds is 78 seconds. 78 divided by 2 is 39, so it lost 2 seconds per day.
In 39 days we have 3369600 seconds in total
And according to question we lost, 1 minute and 18 seconds, i.e., in total 78 seconds
So, in 1-day the clock will be lost
= 78/39 seconds
= 2 seconds

In the diagram below of circle O, chords ab and cd intersect at E.
If measure of arc AC = 72° and measure of arc AEC = 58°, how many degrees are in measure of arc DB?
Answer:
Correct option: 3
Step-by-step explanation:
When we have a crossing of two chords in a circle, there is a property that relates the angles in the intersection point and the arcs defined in the circle. From this property, we have that:
mAEC = (1/2) * (mAC + mBD)
Using the values of mAEC = 58° and mAC = 72°, we have that:
58 = (1/2) * (72 + mBD)
116 = 72 + mBD
mBD = 116 - 72
mBD = 44°
Correct option: 3

which expression represents f^-1(x)?
Answer:
hey !
your answer is C
x=
x/2
Step-by-step explanation:
If the function f(x)=2x then the inverse function is f⁻¹(x) =x/2.
What is a function?A relation is a function if it has only One y-value for each x-value.
The given function is f(x)=2x.
y=2x
Interchange the variables.
x=2y
Now solve for y
y=x/2
Replace y with f⁻¹(x) to show the final answer.
f⁻¹(x) =x/2
Hence, if the function f(x)=2x then the inverse function is f⁻¹(x) =x/2.
