Answer:

Amy bought 4 pounds of coffee.

Step-by-step explanation:

To begin, subtract what she has left, $55.44, from what she began with with, $90. That equation looks like: 90 - 55.44 = 34.56

Now divide $34.56 by the cost of each pound of coffee, $8.64. That equation looks like: 34.56 ÷ 8.64 = 4

So your answer is 4. Amy bought 4 pounds of coffee.

The table shows the number of toys sold at Penelope's Toys and Games store in different years. Find the rate of change in the nu

Aliun [14]

Answer:

Year - (1993 - 1995)

Step-by-step explanation:

Rate of change in the number of toys sold = $\frac{\text{change in number of toys sold}}{\text{Time interval}}$

In the interval (1990 - 1993),

Rate of change in number of toys sold = $\frac{32000-20000}{1993-1990}$

= $\frac{12000}{3}$

= 4000

In the interval (1993 - 1995),

Rate of change = $\frac{42000-32000}{1995-1993}$

= $\frac{10000}{2}$

= 5000

In the interval (2000 - 1995),

Rate of change = $\frac{57000-42000}{2000-1995}$

= $\frac{15000}{5}$

= 3000

In the interval (2006 - 2000),

Rate of change = $\frac{63000-57000}{2006-2000}$

= $\frac{6000}{6}$

= 1000

Therefore, rate of change in the number of toys sold is greatest in the interval (1993 - 1995).

Anestetic [448]

Answer:

108°

Step-by-step explanation:

$- 3x + 69 = - 5x + 43 \: \: \\ (corresponding \: \angle s) \\ \\ 5x - 3x = 43 - 69 \\ \\ 2x = - 26 \\ \\ x = \frac{ - 26}{2} \\ \\ x = - 13 \\ \\ - 5x + 43 = - 5( - 13) + 43 \\ = 65 + 43 \\ = 108 \degree \\ \\ \because m \angle \: 4 = - 5x + 43 \\ (vertical \: \angle s) \\ \\ \huge \red{\therefore \: m \angle \: 4 } \pink{=} \purple{ 108 \degree}$
