Answer:

degree = 120°

A =67 cm²

d=?

note : diameter= 2×radius

area of a circle = πr²

67=22/7 ×r²

67×7=22r²

469=22r²

r²=469/22

r²=21.32

r=4.62

diameter=2 × radius

d= 2× 4.62

d=9.24

d=9

I hope it helps :)

A. in terms of the number of marked elk, what is the relative frequency of male elk, female elk, adult elk, and baby elk? write

mash [69]

The relative frequency of the marked elks are:

Male Elk = 7/30
Female Elk = 4/15
Adult Elk= 173/450
Baby Elk = 26/22

<h3>How to determine the relative frequency?</h3>

From the complete question, we have:

Male = 105
Female = 120
Adult = 173
Baby = 52
Total = 450

The relative frequency of each is then calculated as:

Male Elk = 105/450

Male Elk = 7/30

Female Elk = 120/450

Female Elk = 4/15

Adult Elk= 173/450

Baby Elk = 52/450

Baby Elk = 26/22

<h3>The number of Elks in the park</h3>

Using the data in (a), we can conclude that:

There are 105 male, 120 female, 173 adult, and 26 baby in the park

So,

In order to find numbers that are in between 3/8 and 6/7, Lucy must make common denominators first.

LCM of 8 and 7: 56

Multiply each fraction by the appropriate form of 1:
$\frac{3}{8} * \frac{7}{7}\ AND \ \frac{6}{7} * \frac{8}{8}$

$\frac{21}{56}\ AND\ \frac{48}{56}$

We can immediately see that any fraction with a numerator between 21 and 48 and a denominator of 56 will fit into the criteria Lucy needs.

The correct option is B.

maria [59]

If s represents the number of students, then the number of pizzas is
s/4 + 2 = 9
s/4 = 7 . . . . . . subtract 2
s = 28 . . . . . . multiply by 4

There are 28 students.
