Half of the cards in the deck of 52 are red. There are 14 cards that are both red AND greater than 6. 14/52≈0.27. Hope this helps!
Answer:
Step-by-step explanation:
<u>Wheat flour</u>
- 4 pounds for $8 ⇒ 1 pound for $8/4 = $2
<u>Rye flour</u>
- 5 pounds for $20 ⇒ 1 pound for $20/5 = $4
<u>Equation for total:</u>
57.7r + 23.23 =2.57
Subtract 23.23 from both sides:
57.7r = -20.66
Divide both sides by 57.7
r = -20.66 / 57.7
r = -0.358
round to nearest tenth = 0.4
Step-by-step explanation:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = \frac{k}{x} ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = \frac{k}{8} ( multiply both sides by 8 )
56 = k
P = \frac{56}{x} ← equation of variation
When x = 7 , then
P = \frac{56}{7} = 8
