<h3>Answer:</h3>

24. (A) 1.6

23. (A) 4

<h3>Step-by-step explanation:</h3><h2>24.</h2>

Amy's distance is proportional to the time spent riding, so in 12/30 of the time (12 minutes out of 30 minutes), she will ride 12/30 of the distance:

... (12/30)·(4 mi) = 48/30 mi = 1.6 mi

Sally's speed is (66 mi)/(3 h) = 22 mi/h. Molly's speed is (72 mi)/(4 h) = 18 mi/h.

The difference between their speeds is (22 -18) mi/h. = 4 mi/h.

The value of a house decreases at a steady rate of 20% each year. What is the total percentage loss (to the nearest integer) in

Westkost [7]

Answer: The total percentage loss would be 67%.

Step-by-step explanation:

Since we have given that

Rate of decline each year = 20%

Number of years = 5

We need to find the total percentage loss in value of the house at the end of 5 years.

So, Total percentage loss would be

$1-(1-\dfrac{r}{100})^5\\\\=1-(1-\dfrac{20}{100})^5\\\\=1-(\dfrac{4}{5})^5\\\\=1-(0.8)^5\\\\=0.67\\\\\approx 67%$

Hence, the total percentage loss would be 67%.

Line CH contains points (-2, 6) and H(5, -3) What is the slope of G?

Xelga [282]

Answer:

The slope of line G is $\dfrac{- 9}{7}$ .

Step-by-step explanation:

Given as :

The points of the line CH contains

C = $x_1$ , $y_1$ = - 2 , 6

H = $x_2$ , $y_2$ = 5 , -3

Let The slop of line CH = G

<u>Now, slope of line is </u>

G = $\dfrac{y_2 - y_1}{x_2-x_1}$

i.e G = $\dfrac{- 3 - 6}{5 -(-2)}$

Or, G = $\dfrac{- 9}{5 +2}$

Or,G = $\dfrac{- 9}{7}$

So, The slope of the line CH = G = $\dfrac{- 9}{7}$

Hence, The slope of line G is $\dfrac{- 9}{7}$ . Answer
