Answer:
188 
Step-by-step explanation:
So we can split up this shape into two prisms and then add the two areas.
The volume of a rectangular prism is V = l*w*h
For the first prism, we have our length as 3, our width as 4, and our height as 9. Substituting these values into our volume equation gives us V = (3)(4)(9) = 108 .
Now for the second prism, we have our length as 5, our width as 4, and our height as 4. Substituting these values into our volume equation give us V = (5)(4)(4) = 80
Now adding these two values will give us the area of the entire figure: 108 +80 = 188
Answer:
Area of square = 12.48 cm^2
Step-by-step explanation:
Since the square has all sides equal, and when diagonal is made, square form two right angled triangles. Using Pythagoras theorem we can find the length of side of the square.
where c = 5cm and a==b (square has all sides equal)
Putting value of b = a
So, length of side of square = 3.53
Area of square = (3.53)^2
Area of square = 12.48 cm^2.
Answer:
160 2p coins
Step-by-step explanation:
3/8 x 640 = 240 = 1p coins
240 = 5p coins
240 + 240 = 480
640 - 480 = 160
Answer:
7/2
Step-by-step explanation:
2x=12-5....collectible like terms
2x=7
x=7/2...dividing both side by 2
So 50 per week+3 times number of sales
represent s as number of sales
pay=50+3s
if you want pay to be at least 110 or pay<u><</u>110 so
110<u>></u>pay=50+3s
110<u>></u>50+3s
treat as regular equation: do the saem to both sides so it will stay equal
also isolate the s term
110<u>></u>50+3s
subtract 50 from both sides
60<u>></u>3s
divide both sides by 3
20<u>></u>s
you must make at least 20 sales
