Answer:
5
Step-by-step explanation:
(a + (1/a)2 = a2 + (1/a2) + 2
⇒ (a + (1/a))2 = 23 + 2
⇒ (a + (1/a))2 = 25
⇒ a + (1/a) =
⇒ a + (1/a) = 5
a3+b3=
(a+b)
(a2−ab+b2)
where a=a
and b=1/a.
so sum it up u get -1
Answer:
37.5
you need to convert 75 divided by 200 which will give you 37.5
Answer: 1.5
Step-by-step explanation:
3/4 simplified to 0.75
Multiply 0.75•2
To get 1.5
Or
3/4•2/1
6/4=1 1/2
Which is the same as 1.5
Answer: The required length of steel is 270 cm.
Step-by-step explanation:
Since we have given that
Number of stems = 6
Length of each stem = 45 cm
So, we need to find the length of steel used in the frame.
So, Length of steel = Number of stems × Length of each stem
So, the length of steel becomes

Hence, the required length of steel is 270 cm.
Answer: 6928
----------------------------------------------------------
Explanation:
We have two areas we need to find: The area of the trapezoid and the area of the rectangle. Let's call these areas A1 and A2.
Area of Trapezoid = (height)*(base1+base2)/2
A1 = h*(b1+b2)/2
A1 = 80*(150+100)/2
A1 = 80*250/2
A1 = 20000
A1 = 10000
Area of Rectangle = (length)*(width)
A2 = L*W
A2 = 48*64
A2 = 3072
Subtract the two areas (A1-A2) to get the difference D
D = A1 - A2
D = 10000 - 3072
D = 6928
This difference D is exactly equal to the shaded area.
