4, 49, 64, and 144 are all perfect squares. Because if you think back to it 2^2 is 4, 3^2 is 9, 4^2 is 16, 5^2 is 25. 6^2 is 36, 7^2 is 49, 8^2 is 64, 9^2 is 81, 10^2 is 100. 11^2 is 121. 12^2 is 144 and so on. 12, 24, and 84 do not show up in those numbers, so they are not perfect squares.

Two numbers are in the ratio 7:5 and their difference is 22.Find the numbers​
omeli [17]

Answer:

Let x and y be the two numbers. Then

yx=57  and x−y=20

Cross multiplying the proportion

5x=7y  or y=75x

So, x−y=20

x−75x=20⇒77x−5x=72x=20

⇒x=2140=70

y=75x=75×70=50

So smaller number is 50.

Check :yx=5070=57 and 70−50=20

If y is the square root of x, then x is? Given y = 3 Please explain so I understand, will give brainliest​
LUCKY_DIMON [66]

Answer:x=9

Step-by-step explanation:

The square root is the opposite of squaring a number. When you square a number you times it by itself. So if you square 3 you get 3x3=9. Square root is finding what number you multiply times itself to get 9...

The radius of a circular disk is given as 21 cm with a maximum error in measurement of 0.2 cm. (a) Use differentials to estimate
sergiy2304 [10]

Answer with Step-by-step explanation:

We are given that

Radius of circular disk=r=21 cm

dr=0.2 cm

a.Area of circular disk=A=\pi r^2

d A=2\pi rdr

d A=2\pi (21)(0.2)=8.4 \pi cm^2

d A=8.4\times 3.14

Where \pi=3.14

d A=26.38 cm^2

b.Relative error=\frac{dA}{A}=\frac{26.38}{\pi (21)^2}

Relative error=0.0191

Percentage(%) error=0.0191\times 100=1.91%
