Answer:

Mostly correct

For Q3, you are doing great, you remembered that negative numbers can happen if the exponent is an odd number.

For Q4, I think you were confused with the fractions,

4(i)

(\frac{2}{3} )^{4} = (\frac{2^{4}}{3^{4}}) = (\frac{16}{81}) =0.198

4(ii) is also wrong but I'll let you try to fix it yourself following what I given you for 4(i). You should get 1/64

Hope this helps!

A store sells mugs. Each mug costs the same amount. During a sale, the store reduces the price of each mug by $1.75. Wen spends
Ostrovityanka [42]

Answer:

  • $7.39

Step-by-step explanation:

Let the initial price be x

<u>Then the reduced price is </u>

  • x - 1.75

<u>If 5 mugs cost $28.20, we have equation:</u>

  • (x - 1.75)*5 = 28.20
  • x - 1.75 = 28.20/5
  • x - 1.75 = 5.64
  • x = 1.75 + 5.64
  • x = 7.39

Initial price for 1 mug was $7.39

1. A catering company’s recipe for salad uses a ratio of 2 c of dressing to 4 lb of vegetables. (a) Draw a model for the ratio.
IRISSAK [1]
1. ratio = 2 c of dressing / 4 lb of vegetables

Use two variables: d for the number of c of dressing and v for the number of pounds of vegetables.

Then d / v = 2/4 = 1/2 => d = v/2

Now you can make a table

v     d  

2    1

4    2

6    3

8    2

And you can draw a line for the points (2,1); (4,2); (6,3), (8,4) ... the slope of the graph is the ratio = 1/2

b) I already did it above as part ot the explanation: d/v = 1/2
