Answer:
area = 160160 inches²
area = 1.6016 × 10⁵ inches²
Step-by-step explanation:
The length of the rectangular computer chip is 22 × 10 cm and the width is 7 × 104 cm .
The area of the rectangular computer chip is the product of the length and the width.
area = length × width
area = (22 × 10) × (7 × 104)
area = 220 × 728
area = 160160 inches²
In scientific notation
area = 1.6016 × 10⁵ inches²
160160 is written as 1.6016 × 10⁵ because 1.60160 × 100000 = 1.6016 × 10⁵
Answer:
∠1 = 124 degrees
Step-by-step explanation:
Vertical angles are always congruent
So ∠1 = ∠2
Answer:
2X-3Y = -1
Step-by-step explanation:
given equation is 3X +2Y = -7
FIRST BRING THIS IN SLOPE INTERCEPT FORM
2Y = -3X -7
DIVIDING EACH TERM BY 2
Y = (-3/2)X -7/2
SLOPE OF GIVEN EQUATION IS -3/2
SLOPE OF LINE PERPENDICULAR TO THIS IS NEGATIVE RECIPROCAL HENCE SLOPE OF REQUIRED EQUATION IS 2/3
EQUATION OF STRAIGHT LINE IN POINT SLOPE FORM IS
Y-Y1 = m(X-X1)
Y-1 = (2/3)(X-1)
MULTIPLYING ALL TERMS BY 3
3(Y-1) = 2(X-1)
3Y-3 = 2X -2
2X-2 = 3Y-3
2X-3Y =-3+2
2X-3Y = -1
