Answer:
No, diagonal of square C is 70.71ft
Step-by-step explanation:
Given in the question that length of one square = 5 ft
Length of Square C = 10 small squares
1 square = 5 ft
10 square = 5ft * 10
= 50 ft
As we know that in a square all side are of equal length and make an angle of 90° at each corner.
So, by using pythagorus theorem
Diagonal of square² = side² + side²
Diagonal of square² = 2side²
Diagonal of square = √(2side²)
Diagonal of square = √2 (side)
where side = 50 ft
Diagonal of square = √2 (50)
Diagonal of square = 70.71 ft
276.675 or round it to 276.68
Answer:
-$15
Step-by-step explanation:
To find the average yearly change, divide -120 by 8, since it has decreased by $120 over 8 years.
-120/8
= -15
So, the average yearly change in the value of the card is -$15
Answer:
x^2 - 14x + 49
Step-by-step explanation:
(x - 7)(x - 7) = x^2 -7x - 7x + (7)(7)
Answer:
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z----> the scale factor
x----> volume of the larger solid
y----> volume of the smaller solid
we have
substitute
step 2
Find the surface area of the larger solid
we know that
If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared
Let
z----> the scale factor
x----> surface area of the larger solid
y----> surface area of the smaller solid
we have
substitute
