Answer:

131 is the weight of the lightest person in the group

Step-by-step explanation:

Stem                Leaves

13                     1 1 2 2 4 4 6

14                     3 6 6 7 8 9

15                     0 1 4 5 5 7

16                     2 5 5 6 8 9

17                       2 2 7 8

18                    0 2 4 5 5 7 8

19                    1 2 2 3 4

20                   3 5 5

21                    1 2 6 6 6 8

131 is the weight of the lightest person in the group.

If we look closely the stem has the 13 as the lowest number. And corresponding to it the least number is 1.

Therefore the lightest weight person is 131 .All other weights are greater than 131 e.g 132 , 134 and 136 .

The data shows there are 131 ,131, 132,132,134,134, and 136 weights in the least weight group. So out of these 131 is the smallest.

Mr datu has enough money to pay 8 workers for 15 days if he adds 4 more workers for how long can he pay at the same rate?
vesna_86 [32]

Answer:

10 days

Step-by-step explanation:

Mr Datu can pay 8 workers for 15 days,

Then at the same rate he can pay 1 worker for the number of days = 15×8

                                                                                                                = 120

If he adds number of workers = 4

Then total number of workers = 8 + 4 = 12

With the same rate Mr Datu can pay 12 workers for number of days = \frac{120}{12}

                                                                                                                 = 10 days

Therefore, Mr Datu can pay 12 workers for 10 days a the same rate.

Given m || n, find the value of x and y
Anika [276]

Answer:

x = 16 and y = 121

Yes, its a long process.

Step-by-step explanation:

vertical angles are congruent given that: we do this

(4x-5)+(4x-5)+y+y=360

or

2(4x-5)+2y=360

divide both sides by 2

(4x-5)+y=180

distribute (there is an invisible 1 beside the parentheses of 4x-5)

4x-5+y=180

add 5 to both sides

4x+y = 185

subtract y from both sides

4x = 185-y

divide both sides by 4

x = (185-y)/4

note that (4x-5) is also EQUAL to (3x+11)

4x-5=3x+11

subtract 3x from both sides

x-5=11

add 5 to both sides

x = 16

Now that we know what x is, we can substitute it in the equation we got from 2(4x-5)+2y=360

Our equation was

x = (185-y)/4

16 = (185-y)/4

Multiply both sides by 4

64 = 185-y

Subtract 185 from both sides

-121=-y

multiply both sides by -1

121 = y

A square and a rectangle have the same perimeter. The rectangle is 13 cm long and 7 cm wide.
lorasvet [3.4K]

<u>Solving</u>

Knowing that we have the information needed we will first find the perimeter of the rectangle.

Rectangle:
Length: 13cm

Width: 7cm  

Formula: L+L+W+W

13+13+7+7 = 40cm

Meaning the perimeter is 40cm and we can use this to find the length of a square. From general knowledge we know that all sides of a square is equal.

So if we divide the 4 sides by 40 we will get our answer.

40 ÷ 4 = 10

So B would be our answer...

<u>Statement</u>

<u />

Therefore the length of a side of the square is 10cm, meaning answer B is correct.
