Answer:
10+6=16
Step-by-step explanation:
From your work on parts (a) and (b), you know that
.. r = 3.50
.. s = 140
The composite index of production cost from 2007 to 2009 is 114.2.
(c) If the production cost in 2007 was RM50, then in 2011 it was
.. RM50 * (2009 index) * (2011 index) = RM50 * 1.142 * 1.200 = RM68.52
Answer: 96∘
Step-by-step explanation:
Answer:
3/7 and 4/14
Step-by-step explanation:
a) 3/7 is not an equivalent of 6/21 because when you multiply the numerator and the denominator by 2 you get: 6/14
b) 4/14 is not an equivalent
Answer:
Given: Quadrilateral P QR S is a rectangle.
To prove :PR= Q S
Construction : Join PR and Q S.
Proof: In Rectangle PQRS, and
→ taking two triangles PSR and Δ QRS
1. PS = Q R
2. ∠ PS R = ∠ Q RS [Each being 90°]
3. S R is common.
→ ΔP SR ≅ Δ Q RS → [Side-Angle-Side Congruency]
∴ PR =Q S [ corresponding part of congruent triangles ]
Hence proved.
