Answer:
C) 123 cm^2
Step-by-step explanation:
well if we find CD we can cut striat down C and do area of a triangle plus the area of the rectangle.
to find CD you need length of BC
BC^2 = AC^2-AB^2 --> BC^2 = 400-100 --> BC^2 = 300
BC = 300^2 --> about 17 causeing CD being 4
now we have info
triangle area is BxHx 1/2 --> 17x10x1/2 --> 85cm^2
Now we do the small rectangle area is BxH --> 4x10 --> 40cm^2
85 + 40 = 125cm^2
the only one close is 123cm^2
142/65 or in decimal form : 2.18461538… hope this helps!!!
Answer: 7/8
Step-by-step explanation: Notice that 1/2 and 3/8 are unlike fractions. Our first when adding unlike fractions is to get a common denominator.
The common denominator of 2 and 8 will be the least common multiple of 2 and 8 which is 8.
To get an 8 in the denominator of 1/2, we multiply the numerator and the denominator by 4 which gives us 4/8.
Notice that 3/8 already has an 8 in the denominator so we leave it how it is.
Now we are adding like fractions.
To add like fractions, or fractions that have the same denominator, simply add the numerators and keep the original denominator.
So here, if we add the numerators we have 4 + 3 which gives us 7 and we put this over our original denominator which is 8 and we have our answer. Also, notice that 7/8 is in lowest terms so it's our final answer.
This means that 3/8 + 1/2 = 7/8
