Answer: 65
Step-by-step explanation:
since the square root of 8 is 64 and 65 is closest to 64
Scale factor shows by how much the original model has been multiplied or divided by to get the measurements of the drawing .
In this case the ladybug is 8 mm long but drawing length is 2 cm.
Let’s convert both into the same units
2 cm -20 mm
Original - 8 mm
Painting -20mm
X - scale factor
20 = X * 8
X = 20/8 = 2.5
The ladybug has been multiplied/ enlarged by a scale factor of 2.5 to draw the painting
Hello!
You have to find out how many cubes are in 1 layer
You do this by multiplying the amount across by the amount along the side.
12 * 6 = 72
Divide this by the amount of cubes
288 / 72 = 4
There are 4 layers
The answer is 4
Hope this helps!
Answer:
Step-by-step explanation:
ΔADB is a right angled triangle. So, use Pythagorean theorem.
Altitude² = hypotenuse² - base²
= (2√5)² - (3√2)²
= 2²* (√5)² - 3²*(√2)² = 4*5 - 9*2 = 20 - 18 = 2
Altitude = √2
Base of ΔABC = 3√2 + √2 = 4√2 cm
Area =
