Answer:
Rs 1400
Step-by-step explanation:
Let us take the required number be x. According to question ,
=> 25% of x = Rs 350
=> 25/100 × x = Rs 350
=> x = Rs 350 × 100 / 25
=> x = Rs 1400
<h3>
• Hence the required answer is Rs 1400.</h3>
Answer:
Could you please show the circle ?
Step-by-step explanation:
Answer: 48 sq. cm
Step-by-step explanation:
The area of the similar shapes is similar.
We use scalar factor to get the area of the bigger or the smaller figure by using the area of the given figure.
In the given figure , Area of the small pentagon = 32 sq. cm
Scale factor for the bigger pentagon = 1.5
Then , the area of the bigger pentagon would be = (Scale factor) x (Area of the small pentagon)
= 1.5 x (32 sq. cm)
= 48 sq. cm
Hence, the area of the larger pentagon = 48 sq. cm
Set 2x=x²-3 to each other.
Subtract 2x from both sides and get the following
x²-3-2x
Rearranging the formula to make factoring easier, we get
x²-2x-3
Factor and you should get the following:
(x-3)(x+1)
set both equal to 0 and solve for x.
x-3=0⇒x=3
x+1=0⇒x=-1
Now plug both of these values back into one of your original equations to get your y-values. It does not matter which equation you plug your xs back into due to the fact they intersect at the same x, and thus will also intersect at the same y.
For times sake,
y=2x
plug in x=3 and get y=6
plug in x=-1 and get y=-2
Ergo, the equations y=2x and y=x²-3 intersect at
(3,6) and (-1,-2)
x = √(9 × 16) = √144 = 12 cm
