Answer:
Step-by-step explanation:
The figure shown here consists of two pieces:
- A hemicircle
- A triangle
So, the total area of the figure is the sum of the areas of the two parts.
The area of the hemicircle is given by:
where
r = 4 in. is the radius (half the diameter, which is 8 inches)
Therefore,
The area of the triangle is given by
where
b is the base
h is the height
Here we have:
h = 8 in. is the height
The base is the total length (16 in.) minus the radius of the circle, so
So the area of the triangle is
So the total area of the figure is
Answer:
0.60
Step-by-step explanation:
In the category of pets
22 students had a cat = P(C)
17 students had a dog = P(D)
9 students had both a dog and a cat = P(C and D)
The formula to find the Probability of two events =
P(C or D) = P(C) + P(D) - P(C and D)
P(cat or dog) = P(cat) + P( dog) - P(cat and dog)
P(cat or dog) = 22/50 + 17/50 - 9/50
P(cat or dog) = 0.44 + 0.34 - 0.18
P(cat or dog) = 0.60
The probability the student will have a dog or a cat is 0.60
Answer:
the answer is 36q^7
Step-by-step explanation:
multiply the bases and add the exponents
Answer:
x = 11
Step-by-step explanation:
3x - 5 = 2x + 6
Add 5 to each side:
3x = 2x + 11
subtract 2x from each side:
x = 11
Substitute to check:
3x - 5 = 2x + 6
3 ( 11 ) - 5 = 2 ( 11 ) + 6
33 - 5 = 22 + 6
28 = 28
9t=c would be the answer since it's just asking for the equation
