Answer:
A) Canned and Packet
Grain, Meat and Vegetables
B) Let C = canned goods, let P = packet goods
20C + 7P
Let G = grain, let M = meat, let V = vegetables
7G + 3M + 17V
C) The number of grain and packet goods are the same in each expression, as this food group has been packaged in the same way.
The other variables in both expression are different. The meat and vegetable food groups have been separated in the second expression, whereas they are part of the same group in the first expression.
Answer:
Step-by-step explanation:
Add together: 2 2/3 hrs and 2 3/4 hrs:
First determine the LCD of these two fractions. The LCD here is 3*4 = 12.
Rewrite the given times using this LCD:
2 8/12 + 2 9/12
Adding 2 and 2 results in 4; adding 8/12 and 9/12 results in 17/12, or 1 5/12.
The final result is 4 + 1 5/12, or 5 5/12.
The movie and dinner together lasted 5 5/12 hrs.
If movie and dinner started at 3:00, dinner would have finished at
3:00 + 5:5/12, or
8:25 p.m. (since 5:5/12 is the same as 5:25).
Finished eating at 8:25 p.m.
P(x)=(x-(-5))(x-(-1))(x-2)(x-2)
P(x)=(x+5)(x+1)(x-2)^2
Answer: V = B · h
<u>Step-by-step explanation:</u>
Volume (V) = Area of the base (B) × height (h)
The Area of the base (B) depends on the shape of the base. For example:
- Triangular prism = Area of a Triangle × height
- Rectangular prism = Area of a rectangle × height
- Pentagonal prism = Area of a pentagon × height
Answer:
41.883
Step-by-step explanation:
c^2 = 29^2 + 13^2 - 2(29)(13)(cos 41)
c^2 = 841 + 169 - 754(-0.987)
c^2 = 1010 + 744.198
c^2 = 1754.198
c = 41.883
