perimeter of two similar triangle are 40cm ; 50cm;then ratio of the area of first triangle to the area of 2nd triangle is_____

Answer»

answer:

16:25

step-by-step explanation:

perimeter of 1st triangle/perimeter of 2nd triangle=40/50

=> side of 1st triangle/ side of 2nd triangle=4/5

therefore area of 1st triangle/area of 2nd triangle= (4)^3/(5)^

= 16/25

Please find the HCF using euclids division lemma.

Answer»

Given :-

i) 420,130

ii) 616,32

iii)60,84

To find :-

The H.C.F of given NUMBERS by Euclid DIVISION LEMMA

Euclid division lemma =a=bq+r

A.T.Q :-

i) 420,130

=> 420=130×3+30

=> 130= 30×4+10

=> 30= 10×3+0

So the H.C.F of 420 ,130 is 10

ii) 616,32

=> 616=32×19+8

=> 32= 8×4+0

So the H.C.F of 616 ,32 = 8

iii) 60,84

=> 84= 60×1+24

=> 60=24×2+12

=> 24=12×2+0

So the H.C.F =12

Thus The H.C.F of these numbers is

=> 10 ,8 and 12

14.

The quadratic equation x2 - 4x + k=0 has distinct real roots if

Answer»

the equation

x² - 4x + K = 0

has distinct and real roots.

hence,

b² - 4AC > 0

(-4)² - 4(1)(k) > 0

16 - 4K > 0

16 > 4k

k < $\frac{16}{4}$

k < 4

Hence, the equation x² - 4x + k = 0 has distinct real roots if k < 4

The circumference of the circle is 44 then find the area of the circle and area of the semi circle

Answer»

Answer:

Given :-

Circumference of the circle = 2πr=44

2πr = 44

2×22/7 × R = 44

r = 44×1/2×7/22

r = 7CM

:. RADIUS of the circle = 7cm.

Area of circle = πr²

= 22/7×7×7

= 22×7

= 154cm²

Area of semi circle = 1/2 area of circle

= 1/2 ×154

= 77 cm².

49.	. If (a/b)^(x-1)= (b/a)^(x-5) , then the value of x
Answer» Step-by-step EXPLANATION: (a/b) ^(x-1)=(b/a)^(x-5) (a/b) ^(x-1)=(a/b)^-(x-5) BASES are EQUAL then EXPONENTS are equal (x-1) =-(x-5) x-1=-x+5 x+x=5+1 2x=6 x=6/2 x=3

49.

. If (a/b)^(x-1)= (b/a)^(x-5) , then the value of x

Answer»

Step-by-step EXPLANATION:

(a/b) ^(x-1)=(b/a)^(x-5)

(a/b) ^(x-1)=(a/b)^-(x-5)

BASES are EQUAL then EXPONENTS are equal

(x-1) =-(x-5)

x-1=-x+5

x+x=5+1

2x=6

x=6/2

x=3
