Answer:
Yes, she is correct. If she did 100% of the work time, it would be 15 hours, so instead of multiplying by 1, we multiply by 1.2. 15 times 1.2 is infact 18. So she is justified in saying that she spent 120% more time this week.
Well there must be a shape labelled A on a graph which u have to reflect in to y=-x section
Okay so this is confusing its asking how much he ate of the left over pizza so 3/4 is 75% and he ate a quarter which is 25% meaning he ate 25% of the left over pizza?
<span>The diagonals of a parallelogram bisect each other.
So we just equate the two equations BE and DE
2x^2 - x = x^2 + 6
2x^2 - x - x^2 - 6 = 0
x^2 - x - 6 = 0
This is quadratic eqn. So we obtain.
(x - 3) ( x + 2) = 0
Setting each to 0 and solving for x, we have that x = 3 and x = -2
So we have two possible values for BD.
But Since BE = DE then we can simply double each
If x = 3 BD = 2 (2(3)^2 - 3) = 2 ( 18 - 3) = 30 units
If x = - 2 BD = 2((-2)^2 -3 ) = 2 (8 - 3) = 10 units</span>
The required salary of Juma in July month is sh.9600.
Given that,
he spent half of his July salary on school fees and two-thirds of the remainder on food.
he spent sh.3200 on food.
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements.
In the question,
Let the slay of Juma in July be x,
Juma spent half of his July salary on school fees = x/2
two-thirds of the remainder on food = 2/3 * x/2 = x/3
he spent sh.3200 on food i.e.
x / 3 = 3200
x = 3200 * 3
x = 9600
Thus, the required salary of Juma in July month is sh.9600.
