Answer:
112 cm²
Step-by-step explanation:
The surface area is the sum of the area of all the 6 faces, that is
area = area of 2 purple + area of 2 green + area of 2 orange
= 2(4 × 8) + 2(2 × 8) + 2(4 × 2)
= (2 × 32) + (2 × 16) + (2 × 8)
= 64 + 32 + 16
= 112 cm²
Answer: 54000 cube cm
Step-by-step explanation:
Let h be the height of the box kite,
Also the length of one face = 30 cm,
Hence, the total area of the kite box that is covered by the fabric
= 4 × Area of one face
= 4 × 30 × h
= 120 h
According to the question,
120 h = 7200
h = 60 cm
Hence, the height of the box = 60 cm,
The volume inside the kite = The base area of the box × Its height
= 30² × 60
= 900 × 60
= 54000 cm³
Answer:
Folow these steps:
find the slope:
equation for slope: y2-y1 / x2- x1
4-2 / 4-1
2/3 is the slope
y=mx+b
y=2/3x+b
Now just plug in the x and y of either point into the equation. IM using (1, 2)
2=2/3(1)+b
2=2/3+b
b=1 1/3
Now that we have the y intercept and slope, construct the equation:
y=2/3x+1 1/3
Step-by-step explanation:
An example for #1 would be that: 15 is divisible by 3, but not 9. every third multiple of 3, (9, 18, 27,...) is divisible by 9 because 9 is three times the size of 3.
For part two the first number that I thought of is 23.
0
its a trick naw?
all those numbers but once multiplied by 0 its 0 no matter what
