The area of a square ice rink is 400 yd.². What is the perimeter of the rink in yards

Mathematics
1 answer:
MakcuM [25]3 years ago
8 0

Answer:

80 yd^2

Step-by-step explanation:

Since the formula for squares is s^2, we can use this to set up an equation, which is

s^2=400

If we square root this, we get

s=20

The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2

Find the equation of the line with a slope of 2/5 and containing the point (10,6).
Kipish [7]

Use the poin-slope form of the equation of a line:-


y - y1 = m(x - x1) (where m = slope and the point is (x1, y1))


Plugging in the given values:-


y - 6 = 2/5(x - 10)


multiplying through by 5:-


5y - 30 = 2(x - 10)

5y - 30 = 2x - 20

5y = 2x + 10


In standard form the equation is


2x - 5y = -10 (answer)

Viktor [21]

Answer:

\frac{3}{4}

Step-by-step explanation:

Total number of the students in the pep squad = 12 students

The number of the students wearing white shirts = 3 students

The number of the students wearing blue shirts = 6 students

Either white or blue shirts indicate that the students wearing white shirt or blue shirt.

Thus, number of students wearing either white or a blue shirt = 3 + 6 students = 9 students

So,

The fraction is:- \frac{9}{12}=\frac{3}{4}

The perimeter of a playing field for a certain sport is 334ft. The field is a rectangle, and the length is 47 ft longer than the
babunello [35]

Answer:

The dimensions of the rectangle = 60ft by 107ft

Where 60 ft = Width of the playing field

107ft = Length of the playing field

Step-by-step explanation:

A playing field is Rectangular is shape, hence,

The formula for Perimeter of a rectangle = 2(L + W)

P = 334 ft

L = 47 + W

W = W

Hence we input these values in the formula and we have:

334 = 2(47 + W + W)

334 = 2(47 + 2W)

334 = 94 + 4W

334 - 94 = 4W

240 = 4W

W = 240/4

W = 60

There fore, the width of this playing field = 60 ft

The length of this rectangle is calculated as:

47 + W

47 + 60

= 107 ft

The length of this playing field = 107ft

Therefore the dimensions of the rectangle = 60ft by 107ft
