Answer:
2000 cm^2/min
Step-by-step explanation:
According to the given question,
12 m^2/h = ? cm^2/min
We know,
1 h = 60 min and 1 m = 100 cm
So, by putting the values we get
- 12 m^2/h = 12 × (100)^2/60
Thus the answer of the given question is 2000 cm^2/min .
Price covered by warranty:
130 x 0.25 = $32.5
Price per repair = $8
Number of repairs available:
32.5 / 8
= 4.0625
Thus, the toaster must break 4 times for the warranty to pay for itself.
Answer:
The 25% discount on AED 4000 will be: 1000 AED
Step-by-step explanation:
Given
In order to determine a 25% discount on the amount AED 4000, all we need means is to multiply 25/100 or (0.25) by 4000.
i.e
Discount amount = 25% of 4000
= 25/100 × 4000
= 0.25 × 4000
= 1000 AED
Thus, the 25% discount on AED 4000 will be: 1000 AED
By the law of cosines, the angle

satisfies

which reduces to

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).
So these are basically isolating the variables.
The first equation is 3g + 5 =17.
In order to isolate the variable, we would have to get g by itself, that means 5 would have to go. In order to do this, we would do the opposite. Since it is positive 5 we would add negative 5, in order for it to disappear. This works because a positive 5 and negative 5 cancel each other out. Whatever you do to one side of the equation you have to do to the other, since we subtract 5 on one side we have to subtract 5 on the other. Therefore we would do 17-5.
Now we have 3g=12
We know that 3g is basically 3 multiplied by g. The opposite of multiplication is division.Therefore we would divide by 3 on both sides.
The answer to the first question would be g= 4.
And if you want to check if your answer is correct you plug the value in.
So
3(4) + 5 =17
