A fence is to be enclosed around a square park of side 15m. Atleast how many metres of fencing are needed?

Answers

Answer: 60 m

Step-by-step explanation:

The park is said to be square which means that all of its sides are equal.

If the fence is supposed to be put around the park, it is an indirect question asking for the perimeter of the square.

Perimeter of a square:

= 4 * length

= 4 * 15

= 60 m

Answer:

slope and y-intercept of the graph of 25x -20y =100

Answers

Step-by-step explanation:

First, we need to put this standard form into slope-intercept form

To do this you need to move the "y" to all by itself

-25x+25x-20y=100-25x

-20y=100-25x

y=5/4x-5

Answer:

y=5/4x-5

The slope is-5/4 and the -intercept is (0,5)

How to find the slop?

Locating the y-intercept on a graph requires knowing the value of y at x=0. This is where the graph intersects the y-axis.

25x−20y=100

20y = 100 + 25x

20y=100+25x

y = [tex]5 + \frac{5}{4}[/tex]

She concluded that the slope is   [tex]\frac{5}{4}[/tex]

​and the y-intercept is (0,5).

y = mx + b where m is the slope and b is the y-intercept. So, the slope is 5/4 and the y-intercept is -5.

The slope is-5/4 and the -intercept is (0,5)

Finding the value of y at x=0 will allow you to locate the y-intercept on a graph. The graph's intersection with the y-axis occurs here.

Answers

Answer:

8

Step-by-step explanation:

There are two ways to solve this!

1. Use the Pythagorean Theorem

a^2 + b^2 = c^2

6^2 + b^2 = 10^2

100 - 36 = b^2

64 = b^2

8 = b

2. Shortcut using 3-4-5 triangles

A 3-4-5 triangle has to do with the ratios of each side.

In this case, it's 6-8-10, as each number is multiplied by two with the same 3-4-5 ratio. This is a good shortcut for these types of problems and will be handy on tests like the SAT as well! :)

X, Y and Z are partners in a firm in the ratio of 1/2 :1/3:1/6
Y retires from business and
X and Z purchase his share of profit in the ratio of 3:2. Find out new ratio ​

Answers

Answer:

6:2

Step-by-step explanation:

X share from old ratio is 1/2

Y share from old ratio is 1/3

Z share from old ratio is 1/6

Now, we are told Y retires and that X and Z purchase his shares.

Thus;

Amount X took from Y = 1/2 × 1/3 = 1/6

Amount Z took from Y = 1/6 × 1/3 = 1/18

Thus, new share of X is now; 1/6 + 1/2 = 2/3

New share of Z is now; 1/18 + 1/6 = 4/18 = 2/9

Ratio is now X:Z = 2/3 : 2/9 = 6:2
