Answer:
C. the Inverse Property of Multiplication (this says that a/b * b/a = 1)
A,
lower stated limit of class123 to 125 = 123
upper stated limit of class123 to 125 = 125
b.
lower stated limit of class129 to 131 = 129
upper stated limit of class129 to 131 = 131
c,
lower real limit of class123 to 125 = 122.5
upper real limit of class123 to 125 = 125.5
d.
lower real limit of class129 to 131 = 128.5
upper real limit of class129 to 131 = 131.5
e. mid-point of class interval 120 to 122 is 121
f. Not sure
Answer: p - 0.2p
Step-by-step explanation:
Given the following :
Original Price of tennis racket = p
Mark down or discount on original price = 20% of original price = (20/100) × p = 0.2p
Amount after discount = Amount paid by Natasha
Amount after discount = Original price - Discount
Amount after discount = p - 0.2p
Amount paid by Natasha = p - 0.2p
Answer:
Tory=14 Quentin=14
Step-by-step explanation:
Sister and brother same age
s=sister b= brother
s=b
Tory=s+3 Quentin =2b-8 = 2s-8
EQUATION
s+3 = 2s-8
3=s-8
11=s
sister=11 brother = 11
Tory=11+3=14 quentin=2(11)-8 = 22-8=14
