Perimeter is the total length of all sides. 72 divided by 4 equal sides of a square will give you the value of a. 72 divided by 4 is 18. The value of a is 18 yards.

Answer:

Step-by-step explanation:

A square has 4 sides of equal length.

The perimeter of the square is the sum of the lengths of the sides of the square.

P = perimeter; a = length of 1 side

P = a + a + a + a

P = 4a

We are told the perimeter is 72 yd.

4a = 72 yd

Divide both sides by 4.

a = 72/4 yd

a = 18 yd

Answer: 18

A turtle walked 1/2 mile at the rate of 1/5 mile per hour. how long did it take?

mash [69]

$speed=\frac{distance}{time}\ \ \ | multiply\ by\ time\\\\
speed*time=distance\ \ \ | divide\ by\ speed\\\\
time=\frac{distance}{speed}\\\\
distance=\frac{1}{2}mile\\
speed=\frac{1mile}{5hour}\\\\
time=\frac{\frac{1}{2}mile}{\frac{1mile}{5hour}}=\frac{1}{2}mile*5\frac{mile}{hour}=\frac{5}{2}hour=2,5h\\\\
It\ will\ take\ 2,5 \ hours.$

What is the point slope form of the line with slope −1/4 that passes through the point (−2, 9) ?

Solnce55 [7]

Answer:

Step-by-step explanation:

slope = -1/4 ;(-2,9)

Point slope form : y- y₁ = m(x-x₁)

y - 9 = -1/4 (x - [-2])

y -9 = -1/4 (x + 2)

y - 9 =-1/4x - (1/4) * 2

y - 9 = -1/4x - 1/2

y = *1/4x - 1/2 + 9

y = -1/4x + 17/2

Two dices were thrown in a single toss. What is the probability that they will show:

Anika [276]

Answer:

1)5/36

2)1/9

3)11/36

4)8/9

5)1/6

Step-by-step explanation:

E: throwing two dice

Two dice thrown in a single toss,

in this event the outcomes may

be (1,1),(1,2).....(1,6),(2,1).....(2,6),(3,1).......(6,6)

total 6×6 outcomes: 36 outcomes

here,total possible outcome is 36

P(of anything)=(Total no. of favourable outcome/total possible outcome)

now, (1)sum of 8

we get sum of 8 only when it comes

(2,6),(3,5),(4,4),(5,3),(6,2)

Total no. of favourable outcome is 5

P(getting sum of 8)= 5/36

2) sum of 5

we get sum of 5 only when it comes

(1,4),(2,3),(3,2),(4,1)

Total no. of favourable outcome is 4

P(getting sum of 5)= 4/36=1/9

3)sum of 7 or 8

we get sum of 8 only when it comes

(2,6),(3,5),(4,4),(5,3),(6,2)

or, get 7 when it comes

(1,6),(2,5),(3,4),(4,3),(5,2),(6,1)

Total no. of favourable outcome is 11

P(getting sum of 7 or 8)= 11/36

4)sum to be not 9

we get sum of 9 only when it comes

(3,6),(4,5),(5,4),(6,3)

Total no. of favourable outcome is 4

P(getting sum of 9)= 4/36=1/9

here,we have to find probability of getting (not 9),

which is equal to : 1- probability of getting 9

=1 -1/9= 8/9

5) At least 10

atleeast 10 includes 10 to maximum (12)

i.e, 10,11&12

fav outcome: (4,6),(5,5)(6,4) & (5,6),(6,5) & (6,6)

total no. of fav outcome is 6

probability (atleast 10)=6/36 =1/6
