Find the cost of fencing a square garden of side 45m at the rate of Rs 25 per metre

viktelen [127]

<h3>♫ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Calculate the perimeter:

perimeter = (45 x 4)

perimeter = 180

Multiply this by the cost per meter:

180 x 25 = 4500

It would cost Rs. 4500

aliina [53]

Answer:

$\displaystyle 14$

Step-by-step explanation:

we are given two temperature

4 degrees and -10 degrees

since it says to figure out the changed

substract

$\displaystyle 4 - ( - 10)$

remove parentheses and change its sign

$\displaystyle 4 + 10$

simplify addition:

$\displaystyle 14$

and we are done!

Three fifths of the children in a school are boys. 7/8 of the girls in the school are right-handed. What fraction of the childre

Kaylis [27]

Answer:

To find the answer we only need to know,

Total no.of girls and Total no.of right handed girls.

So,

Total no.of right handed girls = 7/8

Total no.of girls = 8/8 (as given in question)

Total no.of left handed girls is,

(Fraction of total no.of girls) - (Fraction of total no.of left handed girls)

= 8/8 - 7/8

= 1/8

∴ 1/8 of the girls in the school are left handed.

A set of twins, Andrea and Courtney, are initially 10 years old. While Courtney remains on Earth, Andrea rides on a spaceship th

SVETLANKA909090 [29]

The initial age of 10 years and the spaceship speed of 0.60•c, gives the Andrea's age at the end of the trip as 18 years.

<h3>How can Andrea's new age be calculated?</h3>

The time dilation using the Lorentz transformation formula is presented as follows;

$t' = \frac{t}{ \sqrt{1 - \frac{ {v}^{2} }{ {c}^{2} } } }$

From the question, we have;

The spaceship's speed, <em>v</em> = 0.6•c

∆t = Rest frame, Courtney's time, change = 10 years

Therefore;

$\delta t' =\delta t \times \sqrt{1 - \frac{ {(0.6 \cdot c)}^{2} }{ {c}^{2} } } = 8$

The time that elapses as measured by Andrea = 8 years

Andrea's age, <em>A</em>, at the end of the trip is therefore;

A = 10 years + 8 years = 18 years
