CaHeK987 [17]

Answer:

a. 35 *gh or 35 gh

b. 60 *mn or 60 mn

Step-by-step explanation:

The fewest number of symbols and characters can be obtained by multiplying the constant numbers with the constant numbers and variables with the variables.

a. The co efficients 5 and 7 are multiplied to get 35 and g is multiplied with h to get gh. So the answer is 35*gh. It can be further simpliefied into 35 gh

b. The co efficients 3,4 and 5 are multiplied to get 60 and m is multiplied with n to get mn. The answer is 60* mn. On further simplificaation we get 60 mn.

Kenzie has. 4 pages of homework to do. If she can finish 1/3 of a page in one hour how many hours will her homework take?
Maru [420]

Answer:

It will take her 4 1/3 hours

Step-by-step explanation: so you know you needed to  add 4 and 1/3 and you turn the 4 into 4/1 and 1/3 and since it adding you have to have the same denominator and you multiply 1x3 and if you do it on the bottom you have to do it on top so you also do 4x3 and 4x3 is 12 and one 1x3 is 3 and so you don't have to have to do it on the other fraction because now they have the same denominator now and now you add 12/3 + 1/3 and you shall get 13/3 and then you divide 13 divided by 3 and you shall get 4 1/3 and that shall be your answer.

hope it helps you!

Which graph best represents the download speed of a large file
stellarik [79]

Answer:

This question is incomplete

Step-by-step explanation:

This question is incomplete. However, there are mainly four types of graphical representations in mathematics; line graph, bar graph (and histogram), pie chart and cartesian graph. The most suitable representation for fluctuating data sets of the same variables on each of the y and x-axis is the line graph. Since download speed will fluctuate during the course of a download, the correct type of graph to be used here will be the line graph. And the exact type of line graph that will be used here is a simple line graph. A simple line graph is a type of line graph in which one line is drawn on the graph. A simple line graph is usually used to represent two variables (in this case data downloaded per time).
