Answer: 21m

Step-by-step explanation:

From the question, we are informed that the scale drawing of a playground is 4 cm wide and 6 cm long and that the playground is 14 m wide.

Let the length of the playground be represented by x. Therefore,

4/6 = 14/x

4 × x = 14 × 6

4x = 84

x = 84/4

x = 21

Therefore, the length is 21m

BARSIC [14]

= root 45 - 3 root 20 + 4 root 5
= root 9 * root 5 - 3 * root 4 * root 5 + 4 root 5
=3 root 5 - 3 * 2 * root 5 + 4 root 5
= root 5 ( 3 - 6 + 4 )
= root 5 *1
= root 5

The perimeter of a rectangle is 52 cm. If its width is 2 cm more than one-third of its length, find the dimensions of rectangle.

Jobisdone [24]

Answer:

(B) 18 cm x 8 cm

Step-by-step explanation:

let the length be x,

then the width is $\frac{1}{3}$ x + 2

2( $\frac{1}{3}$ x + 2 + x ) = 52

$\frac{1}{3}$ x + 2 + x = 26

$\frac{4}{3} x$ = 24

x = (24*3)/4

x = 18

then the length is 18 cm

and width is (1/3)*18 + 2 = 8

Therefore the dimensions are length:width = 18 cm : 8 cm

A line passes through the point (0,-4) and has slope-5. What is the equation of the line in slope-intercept form?

Mazyrski [523]

Y= -5x -4 because you would do slope intercept form and sub the y and x in for -4 and 0

$i^5+i^{-25}+i^{45}$<img src="https://tex.z-dn.net/?f=%24i%5E5%2Bi%5E%7B-25%7D%2Bi%5E%7B45%7D%24" id="TexFormula1" title="$i^5+i

gregori [183]

$i^5+i^{-25}+i^{45}$

Rewrite the term $i^{-25}$

$=i^5+\dfrac{1}{i^{25}}+i^{45}$

Expand each term so we have

$=i(i^2)^2+\dfrac{1}{i(i^2)^{12}}+i(i^2)^{22}$

Use the fact that $i^2=-1$

$=i(-1)^2+\dfrac{1}{i(-1)^{12}}+i(-1)^{22}$

Use the fact that $(-1)^{a}=1$ when a is an even number

$=i+\dfrac{1}{i}+i$

Simplify

$=i-i+i$

$=i$

Let me know if you need any clarifications, thanks!
