Answer:
9. 3.93miles
10. 7.42 cm
11. He doesn't have enough money to buy a hat.
12. $10.02
Step-by-step explanation:
9. ⇒
Yesterday walked=1.74 miles
Today walked=2.19 miles
Total walked both days=(1.74+2.19)=3.93miles
10.⇒
Total growth in a month was (12.72-5.3)=7.42 cm
11.⇒
After buying foods, Daniel has (20.39-8.76)=$11.63
The hat is $12
As, 11.63<12 (11.63 is less than 12)
So, he doesn't have enough money to buy a hat.
12.⇒
Penny has $35
Buying a hat and a scarf, Penny has spent (14.99+9.99)=$24.98
Now, Penny will have (35-24.98)=$10.02
Hope, this helps you.
V=PiR^2H/3
Pi = 3.14 (use pi symbol on calculator)
R is the radius if the cones bottom
H is the height of the cone
Let us assume the number of sandwiches made by Deli = x
Amount of roast beef required for making 1 sandwich = (1/4) pound
Total amount of beef that Marisa started with = 5 pounds
Amount of beef that was left = (3/4) pounds
Then
[(1/4) * x] + (3/4) = 5
(x/4) + (3/4) = 5
(x + 3)/4 = 5
x + 3 = 5 * 4
x + 3 = 20
x = 20 - 3
= 17
So we can see from the above deduction that 17 Deli sandwiches was made by Marisa. I hope the procedure is clear enough for you to understand.
