The perimeter of a court is equal to 246m

<h3>What is Perimeter ?</h3>

Perimeter is the distance covered by a person if she/he moves around the surface,

It is given in the question that

Hana plans to build 3 cricket courts in a local park.

The image is attached with the answer.

The length of one court is 30 m and the wudth of one court is 11m

The amount of fence needed is equal to the perimeter of the courts.

The perimeter of a court is equal to 2(l + b)

For 3 courts = 3 * 2 * ( 30+11)

= 6 * 41

=246 m

Therefore Hana will need 246 m of fencing.

Assume that the readings at freezing on a batch of thermometers are Normally distributed with mean 0°C and standard deviation 1.

andre [41]

Answer:

$P_{60} = 0.254$

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 0

Standard Deviation, σ = 1.00

We are given that the distribution of readings at freezing on a batch of thermometers is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find $P_{60}$

P(X<x) = 0.0600

We have to find the value of x such that the probability is 0.600

P(X < x)

$P( X < x) = P( z < \displaystyle\frac{x - 0}{1})=0.600$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 0}{1} = 0.254\\x = 0.254$

$\bold{P_{60} = 0.254}$

Celeste wants to have her hair cut and permed and also go to lunch. She knows she will need $68. The perm costs twice as much as

fgiga [73]

Total is 68 and the perm is 2 times as much as her haircut and her lunch is $5
so...
2h+h+5= 68 (add like terms)
3h+5 = 68 (subtract 5 from both sides)
-5 - 5
3h = 63 (divide by 3)
h= 21
so if her haircut is 21 dollars
21*2= $42
her perm cost 42 dollars

the sum of the reciprocals of two consecutive even integers is 9/40. this can be represented by the equation shown 1/x + 1/(x+2)

Ivanshal [37]

Answer:

8, 10

Step-by-step explanation:

Multiplying the equation by the product of the denominators, we have ...

40(x+2) +40x = 9x(x+2)

80x +80 = 9x^2 +18x . . . . eliminate parentheses

9x^2 -62x -80 = 0 . . . . . . put in standard form

9x^2 -72x +10x -80 = 0 . . . prepare to factor by grouping

9x(x -8) +10(x -8) = 0 . . . . . factor pairs of terms

(9x +10)(x -8) = 0

Solutions are ...

x = -10/9 and x = 8

The integers are 8 and 10.

I find a graphing calculator to be a nice tool for solving these. It finds zeros easily, so writing the equation so it equals zero is a useful first step.

Which is greater 16/12 or 9/3

zavuch27 [327]

Answer:

$\frac{16}{12} \: \: < \frac{9}{3}$

9/3 is greater

Step-by-step explanation:

$\frac{16}{12} \: \: \: \: \: \: \: \: \: \: \frac{9}{3} \\ \frac{16}{12} \: \: \: \: \: \: \: \: \: \: \frac{9 \times 4}{3 \times 4} \\ \frac{16}{12} \: \: \: \: \: \: \: \: \: \: \frac{36}{12} \\ \frac{16}{12} \: < \: \frac{36}{12} \\ \\ so \\ \frac{16}{12} < \frac{9}{3}$
