Robert has 12 coins totaling $1.45. None of his coins is larger than a quarter. Which ofthe following cannot be the number of quarters he has?

Answers

Answer 1

Answer:
The correct answer is 1 because coin • number = total value. When p = the number of pennies, n = the number of nickels, d = the number of dimes, q = the number of quarters. The total number of coins = p+ n+ d+ q = 12. But if q = 1 then p+ n+ d = 11

Carmen has a sign with dimensions 5 ft × 7.5 ft. She wants to reduce it to make a postcard. Postcard sizes are 3.5 in. × 5 in., 4 in. × 6 in., and 4.25 in. × 6 in. Which size postcard should she use? Explain.

Answers

Answer:

The size of the post card she should use is 4 in. × 6 in.

Step-by-step explanation:

The parameters given are;

Dimensions of sign = 5 ft. × 7.5 ft

Hence, the ratio of the side sizes are;

5:7.5 which is the same as 2:3, therefore, to obtain the most accurate design of the sign on the post card, the size of the post card must be in direct proportion to the size of the sign which gives;

Side length ratio of post card = 2:3 = 4:6 = 4 in. × 6 in.

The size of the post card she should use is therefore = 4 in. × 6 in.

Which explains why the graphs of geometric sequences are a series of unconnected points rather than a smooth curve?The range contains only natural numbers.

The domain contains only natural numbers
.
Exponential bases must be whole numbers.

Initial values must be whole numbers.

Answers

The correct answer is:

The domain contains only natural numbers .

Explanation:

The domain of a geometric sequence is the set of term numbers. This is the position of each term in the sequence: first, second, third, etc.

Since the domain is the set of positions, there are no decimal or fraction numbers in the domain. There would be no "2 and a half" term; it goes from the second to third.

This means that the values between the terms of the sequence have no value, and the graph will not be connected.

Answer: B.

(The domain contains only natural numbers.)
