What does N equal? N equals -5
Answer: 10 7/18
Find the least common denominator.
4 5/9 = 4 10/18
5 5/6 = 5 15/18
Add up the fractions.
4 10/18 + 5 15/18 = 9 25/18
Turn 9 25/18 into a mixed number.
10 7/18
Answer:
168cm^3
Step-by-step explanation:
Q to P is going to be 3cm. it is identical to the length T to U.
R to T , W to Q, S to U is going to be identical to P to V. P to V has been identified as 12 cm.
in the middle of the shape, there are 4 identical triangles. the height time length will give us the area of that one shape:
e.g for shape P to V to W to Q and back to P is one rectangle. the length is 12 cm and the width is 3 cm.
12 x 3= 36
36cm^3 is one rectangles surface area, we have 4 identical triangles that means we need to times 36 by 4.
so 36x4=144.
now on the left and right side, we have two squares. on the right, we have T to U to V to W back to T this has the height of 3 width of 4 then we do 3 X 4 which is 12, we times it by 2 because we have two identical squares.
12 X 2=24
finally we add 24 and 144 = 168cm^3.
hope this helps :)
$64 is 80% of $80. To find how many percent of $80 is $64. $64/$80 = 0.8 or 80%
To find how many percent of decrease, just subtract 80-64=16; $16/$80= 0.2 or 20%
It’s acute, equilateral and isosceles
