Answer:

1a. 58/99

1b. 53/90

1c. 29/50

Step-by-step explanation:

let's start with the easiest one

1.(c)

0.58 = 58/100 = 29/50

that is the simplest possible form, as 29 is a prime number and not a factor of 50.

1.(a)

0.585858585858... = 58×0.0101010101010101...

now, we know that 1/"double digit" (like 1/22) mostly produces a repeating pattern with a period length of 2 after the decimal point.

and we find

1/99 = 0.01010101010101...

so, our solution is

58 × 1/99 = 58/99

that is the simplest possible form, as 58 and 99 do not share any factors.

1.(b)

0.5888888888888... = 0.5 + 0.0888888888888... =

= 0.5 + 8×0.01111111111111... = 0.5 + 8×1/10 × 0.1111111111...

we know how to create 0.11111111111... :

1/9 = 0.111111111111111...

so, our solution is

0.5 + 8 × 1/10 × 1/9 = 0.5 + 8/90 = 5/10 + 8/90 =

= 45/90 + 8/90 = 53/90

this is the simplest possible form, as 53 is already a prime number and not a factor of 90.

Answer:

Step-by-step explanation:

The volume (V) of the prism is calculate as

V = lbh ( l is the length, b the width and h the height )

l = h = 4 × $\frac{1}{3}$ = $\frac{4}{3}$

b = 3 × $\frac{1}{3}$ = 1, thus

V = $\frac{4}{3}$ × 1 × $\frac{4}{3}$ = $\frac{16}{9}$ ft³

Brums [2.3K]

Answer:

5√2

Step-by-step explanation:

Finding distance :-

d = √{ ( 1 -6)² + (4+1)²}
d = √{ -5² + 5² }
d = √{ 25 + 25}
d = √50
d = 5√2

(photo) According to this diagram, what is cos 23°?

Burka [1]

ANSWER

None of the above

EXPLANATION

Recall the mnemonic CAH, from trigonometric ratios.

CAH means the cosine ratio is the ratio of the length of the adjacent side to the length of the hypotenuse.

This implies that,

$\cos(23 \degree) = \frac{length \: of \: adjacent \: side}{length \: of \: the \: hypotenuse}$

The side adjacent to the 23° angle is 12 units and the hypotenuse is 13 units.

This implies that,

$\cos(23 \degree) = \frac{12}{13}$

None of the provided options is correct
