Answer:
Area = 3.3998
Perimeter = 2.9
Step-by-step explanation:
A method for calculating the area of a triangle when you know the lengths of all three sides.
Let a,b,c be the lengths of the sides of a triangle. The area is given by:
Area = √ p ( p − a ) ( p − b ) ( p − c )
where p is half the perimeter, or
a + b + c / 2
p = 1.7 + 1.7 + 2.4 / 2 = 5.8 / 2 = 2.9
a = Area = 3.3998
Heron was one of the great mathematicians of antiquity and came up with this formula sometime in the first century BC, although it may have been known earlier. He also extended it to the area of quadrilaterals and higher-order polygons.
1.
a. your answer is correct
b. 60 and hndreths=60.08
c. 16 and 8 thousanths=16.008
d. 60 and 8 tenths=60.8
e. your answer is correct
f. your answer is correct
2. 16.207, 6.9, 16.19, 16.26
so the greatest is obviously one of the 16's
compare
16.207, 16.190, 16.260
obviously, the order is 16.260,16.207,16.190
then the last one is 6.9 so the order is 16.26,16.207, 16.19, 6.9 and the numbers in order is 2,4,3,1
3. I can't see the puzzle that well, but 11.88 is more than 11.50 since 0.88 is more than 0.50
4. can't see the puzzle that mmuch
hundreths is 0.0x x is the hundrreths since exg 1/100=1 hundreths=0.01
5. remember if the number is more than five round up and if less than 4 round down so
10.5, 10.6, 10.7 10.8 10.9 10.1 10.2 10.3 10.4 would work
6. tenth=0.8 so the numbers could be 17.81, 17.82 17,83
7.rembmber the decimal places and line them up so again
6.081, 6.082 6.083 and so on
8. 1/2=0.5 or 0.50000
9. the greatest decimal
first find the greatest whole number
60
then find all the 60's and read from left to right the numbers after the decimal, the biggest number to the left is bigger, if they are the same, move one place to the right and count again
10. I can't seee the puzzzle very clearly but hte answer is pirates
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
(3 x 2.5) x 2 would be your answer
