Answer: 7 5/7 (the bottom one)

Step-by-step explanation:

30 divided by 2 = 15 (do the same to 42 and get 21)

This then creates the fraction: 15/21

Now, divide this fraction by 3 and get 5/7

Add back in the seven because you aren't dividing the whole number.

Your final answer is now 7 and 5/7 (together: 7 5/7)

Unit price of strawberries at Grocery Mart is $ 1.495 or 150 pennies

Unit price of strawberries at Baldwin Hills Market is $ 1.33 or 133 pennies.

Step-by-step explanation:

1 dollar = 100 pennies

Given:

Cost of 2 pounds of strawberries at Grocery Mart = $ 2.99

Cost of 3 pounds of strawberries at Baldwin Hills Market = $3.99

∵ Cost of 2 pounds of strawberries at Grocery Mart = $ 2.99

∴ Cost of 1 pound of strawberries at Grocery Mart = $\frac{2.99}{2}=\$1.495=1.495\times 100\approx 150\textrm{ pennies}$

∵ Cost of 3 pounds of strawberries at Baldwin Hills Market = $3.99

Cost of 1 pound of strawberries at Baldwin Hills Market = $\frac{3.99}{3}=\$1.33= 1.33\times 100 = 133\textrm{ pennies}$

Therefore, the unit price of strawberries at each grocery store is the cost of 1 pound of strawberries. So, unit rate at Grocery Mart is 150 pennies and at Baldwin Hills Market is 133 pennies.

katrin [286]

Answer:

The number of sides the polygon have 9

Step-by-step explanation:

Given in question as :

For The circle , the central angles measure be 40 °

Let the number of sides of polygon = n

Now . as we know

External angle = $\frac{360^{\circ} }{n}$

Or , 40° = $\frac{360^{\circ} }{n}$

Or, $\frac{360^{\circ} }{n}$ = 40°

So, n = $\frac{360^{\circ} }{40^{\circ}}$ = 9

Hence The number of sides the polygon have 9 Answer
