30 x 28= 840
It's would beat 840 times in half an hour.

Answer with explanation:</h2>
Let x denotes the number of days and y denotes the total change in gas price ( in dollars).
Given : During the past seven days the price of regular gas is decreased by $0.2 each day.
Rate of decrease =$0.2 per day
Then , Total change in gas price = Rate of decrease x Number of days
i.e.
i.e.
(1)
To find the total change in gas price in 7 days , we put x= 7 in (1) , we get
Hence, the total change in gas price in 7 days = $1.4
Answer:
15. {1, 3, 5, 7}
16. nothing empty set { }
17. {0, 1, 2, 4, 5, 6, 7, 8, 10}
Step-by-step explanation:
the U means combining the sets that fit the criteria
the upside down U means what fits both criteria
for 16, it asks for contradicting criteria so there is nothing in the set.

Answer:
1944 in³
Step-by-step explanation:
We are given;
Dimensions of a triangular prism;
- Base is 18 inches
- Length is 9 inches, and
- Length is 24 inches
We are required to determine the volume of the prism
To answer the question we need to know that the volume of a triangular prism is given by;
Volume = 0.5 × Width × height × Length
Therefore;
Volume = 0.5 × 18 in × 9 in × 24 in
= 1944 in³
Thus, the volume of the triangular prism is 1944 in³
