The question in English is
During the week 72 children will visit the park. For each child is prepared a rectangular box, in which to arrange what will be collected during the visit. Each box is 18 cm long and 12 cm wide. How long is the strip of cardboard that is used to make the edge of all boxes.
Let
x ----> the length of the box
y -----> the width of the box
we know that
The perimeter of the box is equal to

we have


step 1
Find the perimeter of one box


step 2
Find the perimeter of 72 box
Multiply the perimeter of one box by 72

Convert to meters
Divide by 100

The measure of angle x is 28
Answer:
0.611 = 61.1%
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% = p/100 = p ÷ 100.
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
Calculate the percent value:
0.611 =
0.611 × 100/100 =
(0.611 × 100)/100 =
61.1/100 =
61.1%;
In other words:
1) Multiply that number by 100.
2) Add the percent sign % to it.
I think the answer is 54 to question B but don't take my word for it.
Answer:
All angle = (110°, 35°, 35°)
Step-by-step explanation:
Given:
Triangle is a Obtuse isosceles triangle
One angle = 35°
Find:
All angle
Computation:
In the Obtuse isosceles triangle, one angle is obtuse and the other two angles are acute so, two equal angles are 35°
So,
Sum of angle property
x + 35° + 35° = 180°
x = 110°
Obtuse angle = 110°
All angle = (110°, 35°, 35°)
