79/58=e^0.055t
1.3620690=e^0.055t
ln 1.3620690=ln e^0.055t=0.055t ln e=0.055t
t=5.6183 years

The perimeter of a rectangular garden is 4534 m. The length is 1125 m more than thrice the width. Find the length and the width

IrinaVladis [17]

Answer:

length = 1696 m

breadth = 571 m

Step-by-step explanation:

perimeter = 4534 m

let breadth be b

so length = b + 1125 m

so

perimeter of rectangular garden = 2(l+b)

4534 m = 2(b+1125m+b) {substituting the value}

or, 4534 m = 2(2b+1125m)

or, 4534 m = 4b + 2250 m

or, 4534 m - 2250m = 4b

or, 2284m = 4b

or, b = 2284m/4

so, b = 571m

so, l = b + 1125 m

= 571 m + 1125m

= 1696 m

Why is -12.3,-9.7,-7.1,-4.5 an arithmetic sequence

Klio2033 [76]

Answer:

Step-by-step explanation:

arithmetic sequence is a sequence , if difference between any two consecutive terms is same for all.

difference of first two terms: -9.7-(-12.3)=2.6

difference of third and seconf term: -7.1-(-9.7)=2.6

and so o, as difference between any of the consecutive terms is same i.e 2.6, the given sequence is arithmetic.

Help this is due tomorrow!!!

Answer:

V = 5.4 cubic meters

Step-by-step explanation:

The formula for the volume of a hemisphere is V = (2/3)πr. Since we know the radius, we can find the volume. Using π = 3.14, plug it in and r for 2.6.

V = (2/3)*3.14*2.6

V = 5.44266667

Rounding to the nearest tenth, we get:

V = 5.4 m^3

Hope this helps. Brainly will be highly appreciated.
