First, convert the percentage to a decimal. You can do this by moving the decimal place two places to the left.
Now, simply multiply that decimal by using a calculator.
Hey there! I'm happy to help!
First, let's find the area of the total trapezoid. To do this, you add the top and bottom side, divide it by two, and then multiply by the height.
We add up the values that make up the top side so we can find find its length.
6.1+8.1+9.5=23.7
The bottom side is 8.1
We add the top and bottom sides.
23.7+8.1=31.8
We divide by 2.
31.8/2=15.9
We multiply by the height, which we can see is 6.2
15.9×6.2=98.58
Now, we find the area of the rectangle that isn't shaded.
6.2×8.1=50.22
We subtract this from the total area of the trapezoid to find the total area of the two shaded triangles.
98.58-50.22=48.36
Therefore, the shaded regions have a total area of 48.36 cm².
Have a wonderful day! :D
The answer to this question is that this is a rhombus
Answer:
The probability is 0.0548 if the weight of the bag of red gravel is 25kg.
Step-by-step explanation:
P(x<25)
=
=
=
=
Using z-table:
P(x<25)
=
=
=0.0548
Hence, the probability is 0.0548.
