1- the answer is 120

$360 - (180 + 60) = 360 - 240 \\ = 120$

2- the answer is 74

$360 - (135 + 77) = 360 - 212 \\ = 148 \\ \\ 148 \div 2 = 74$

3- it's 84
$42 \times 2 = 84$

good luck

A 14-foot piece of string is cut into two pieces so that the longer piece is 2 feet longer than twice the shorter piece. If the

Maurinko [17]

We are given that the shorter piece is x
From your description, the longer piece is 2x + 2
The total length is
x + 2x + 2 = 14
ie
3x + 2 = 14
3x = 12
x = 4

So the length of the shorter piece is 4 ft
Therefore the length of the longer piece must be
(14 - 4) ft = 10 ft

Note: As you missed to identify what we have to find in this question. But, after a little research, I am able to find that we had to find the Mode for the data given in your question. So, I am assuming we have to calculate the the Mode. Hopefully, it would clear your concept regarding this topic.

Answer:

The mode of the data = 75

Step-by-step explanation:

Lets visualize the given data in a table to show the frequency distribution:

Daily expenditure on milk (in Rs) Number of households

0-30 5

30-60 6

60-90 9

90-120 6

120-150 4

Here the maximum frequency is 9.

So, modal class is 60-90.
