A bicycle’s speedometer measures speed to the nearest 0.1 miles per hour. Which is the most appropriate way to report speed usin

Rina8888 [55]

The bicycle`s speedometer measures the speed to the nearest 0.1 mph. So 17.15 mph is not appropriate way to report speed, because then it should measure speed to the nearest 0.05 mph. Also 17 mph and 20 mph are whole numbers and it does not have to be so accurate.
Answer: B. 17.1 mph

Lesson 17 Practice Problems

Elina [12.6K]

Answer:

(a) we get that the fewest number of packages of cups and napkins should buy is 24.

(b) Number of sets of 3 packages of Cups and 2 packages of Napkins will be there.

Step-by-step explanation:

Given that,

Cups are sold in packages of 8.

Napkins are sold in package of 12.

To find:- (a) What is the fewest number of packages of cups and the fewest number of packages of napkins that can be purchased so there will be the same number of cups as napkins?

From the Question,

We have to least number of packages of cups and napkins So, we find the

L.C.M of the given data because it provide the least common multiple.

So, L.c.m of 8 & 12 is

$8= 2\times 2\times2$

$12= 2\times2\times3$

$L.c.m = 2\times2\times2\times3 = 24$

Here we get that the fewest number of packages of cups and napkins should buy is 24.

(b) How many sets of cups and napkins will there be?

Again,

Number of packages of cups should buy = $\frac{24}{8} = 3$

Number of packages of Napkins should buy = $\frac{24}{12} = 2$

Hence

Number of sets of 3 packages of Cups and 2 packages of Napkins will be there.
