Yes, it is shown horizontal for both lines and they will never touch, therefore parallel.

Answer:

YES

Step-by-step explanation:

Becasue the ratio of the length of the sides 6/9 is equivalent to the ratio of of the length of the sides 4/6:

6/9 = 4/6

If you simplify these you can see that they are of the same ratio, so the lines DE and BC must be parallel.

Hope this helps!

Suppose that it is reported in the news that 12% of the people living and working in Kokomo feel that their commute is too long.

Answer:

22.3 minutes

Step-by-step explanation:

The computation of the travel time is as follows:

Given that

$\mu$ = 17

And, the standard deviation is 4.5

P(X≤C) = 0.88

P( x - $\mu$ ) ÷ $\sigma$ ≤ (C - $\mu$ ) ÷ $\sigma$ = 0.88

(C - $\mu$ ) ÷ $\sigma$ = 1.175

c = $\mu$ + 1.175 × $\sigma$

= 17 + 1.175 × 4.5

= 22.3 minutes

Hence, the travel time is 22.3 minutes

(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

A school club visits a science museum. Student tickets cost $5 each. Non-student tickets cost $10 each.

Nataly [62]

Answer:

The correct answer would be, A. y= 25-2

Step-by-step explanation:

A. is correct because B,C,D are all equal to the same thing. When you solve the problems and get the variables by them self you can see that they equal the same thing. So therefore A. is the correct/incorrect option.
