Mathematics
1 answer:
atroni [7]3 years ago
7 0

Answer:

Step-by-step explanation:

If we want to share £5 to the ratio of 1/3 we should follow this steps :

  • our ratio is 1/3 so we should add 1 and 3 together to find the total number of parts : 1+3=4
  • divide the total amount by the number of parts : 5/4 = 1.25
  • multiply each number in the ratio by 1.25 : 1.25*1=1.25 and 1.25*3=3.75

the answer is 1.25 and 3.75

It was obvious from the beginning that the answer would be the last one since ut had two numbers

  • following the same steps you get again in the second question :

6 ; 14

A student scored 66 points on his Psychology 101 midterm. If the average of his midterm and final must be between 78 and 90 incl
Paul [167]

Answer:

range of scores on final exam student get  B is 90 to 100

Step-by-step explanation:

given data

Psychology 101 score = 66

average of his midterm = between 78 and 90

maximum = 100 points

to find out

range of scores on final exam student get  B

solution

we consider here lowest marks need in final = x

so average at two marks should be

equation is  

average marks = 0.5 × ( mid term marks + final marks )      .................1

put here value

78 = 0.5 ×  ( 66 + x )

x = 90

and

90 = 0.5 ×  ( 66 + x )

x = 114

so range 90 to 114

but maximum marks is 100 so

range of scores on final exam student get  B is 90 to 100

PLEASE HELP.
pentagon [3]

Let x represent the number of shirts. Let y represent the number of pens.

If shirts are on sale for $11.99 each, then x shirts cost $11.99x.

If pants are on sale for $12.99 each, then y pants cost $12.99y.

The total cost is $(11.99x+12.99y).

Sarah can spend up to $65. Then an inequality that represents this situation is

11.99x+12.99y≤65 (this inequality holds when Sarah can spend $65 too)

or

11.99x+12.99y<65 (this inequality holds when Sarah can spend less than $65).
