Let’s solve this step by step. :)
First, let’s assign variables for the missing number: x and y.
so the 3 numbers would be x, y and 28
then we have 3 scenarios:
28 + x = 61
28 + y = 76
x + y = 81
Using the first equation, we can get x = 61-28 = 33
Using the 2nd equation, we can get y = 76-28 = 48
then, we can verify if our answer is right by substituting these values in the 3rd equation:
x + y = 81
33 + 48 = 81
81 = 81 ✔️
So the 3 numbers are 28, 33 and 48.
Total area =2triangles+3rctangles
rectangles is small ok so
we can consider the 3 rectangles as 1 big reectangle with base 5+12+13=30 and height 8
area=30*8=240
the 2 triangles
the height is 5 becasue it has to to match with the 5 on the small rectangle
base is 12
2 of them
aera=2*1/2*12*5=60
so total
240+60=300
total surfacea area is 300 in^2
Answer:
Step-by-step explanation:
<u>Use page/min ratio to solve:</u>
- 8/15 = 20/x
- x = 20*15/8
- x = 37.5 minutes
Answer:
2m
Step-by-step explanation:
When the perimeter of square is concerned, all the sides are equal. Since perimeter is the sum of all sides so perimeter of square is equal to 4L
P=4L
8=4L
L=8/4
L=2 m
About 27.5 percent so B is the correct answer
