Step-by-step explanation:
1 out of four cards have flowers on them which it means you can expect a fourth of the 20 twenty cards to have flowers. 20 divided by 4 is five.
Answer:
So the surface area consists of 2 triangles and 3 different rectangles
Triangle area = 1/2 * 8cm * 6cm = 24cm²
Rectangle a area (bottom one) = 17cm * 8cm = 136cm²
Rectangle b area (the one to the left) = 17cm * 6cm = 102cm²
To calculate Rectangle c we need to know the hypotenuse of our triangles
Formula for the hypotenuse is c =
so c = = 10
Rectangle c area = 17cm * 10cm = 170cm²
So the surface area is 2 * 24cm² + 136cm² + 102cm² + 170cm² = 456cm²
The volume is 1/2 * h * a * b = 1/2 * 6cm * 8cm * 17cm = 408cm³
Answer:
4/5 of an hour
Step-by-step explanation:
3/10 of an hour (60 minutes) equals 18 minutes
3/4 of 5 km equals 3.75 km
therefore, you can create a ratio of minutes over km equals min over km
let 't' = time
18/3.75 = t/10
cross-multiply to get this equation:
3.75t = 180
divide each side by 3.75 to get:
t = 48 minutes
48 minutes out of 60 minutes equals 4/5 of one hour
