<span>If
a quantity increases by 25% and then decreases by 25%, will that result be the
original quantity? Explain.
Let’s try to be able to know the answer:
=> Let’s have 10 as the value
Increase by 25%
=> 10 + 25%
=> 10 * .25 = 2.5
=> 10 + 2.5 = 12.5 the new value
Now, decrease this by 25%
=> 12.5 – 25%
=> 12.5 * .25 = 3.125
=> 12.5 – 3.125 = 9.375 or 9.4
Thus, the given statement is false.

Answer:
The answer is 24
Step-by-step explanation:
Gradient of the line formed;
m=
m=
m=
y=mx+c
y=
Replacing for x and y;
1=-3/11*(-5)+c
1=15/11+c
c=1-15/11
c=-4/11
y=
Answer:
Part a)
Exact value 24√3 units
Approximate value 41.6 units
Part b) x=52.1 units
Step-by-step explanation:
Part a)
step 1
Find the exact value
Let
h-------> the blue dotted line
we know that
tan(60°)=h/24
h=tan(60°)*24
Remember that
tan(60°)=√3
substitute
h=24√3 units
step 2
Find the approximate value
h=24√3=41.6 units
Part b)
we know that
sin(53°)=41.6/x
x=41.6/sin(53°)=52.1 units
Answer: You do not have x alone on one side, therefore, you can be certain the equation has no solution!!
Step-by-step explanation: In order for the equation to have a solution it must look like this:
x= and some number
