Answer:
0.90
Step-by-step explanation:
full price discounted total
month 1 49 1 50
month 2 120 5 125
month 3 101 24 125
total 270 30 300
full price discounted total
month 1 0.98 0.02 1
month 2 0.96 0.04 1
month 3 0.808 0.192 1
total x = 0.9 y = 0.10 1
x = 270 / 300 = 0.90
y = 30 / 300 = 0.10
Answer:
y = -20
Step-by-step explanation:
Given that y varies directly with x it means changing x will also cause change in y
Mathematically it can be written as:
y∝x
Removing the proportionality symbol
y = kx
Given y=25 when x=5 Putting the values

Now

We have to find the value of y when x = -4
Putting x=-4

Hence,,
y = -20
Answer:
s/2-6

(happy to help)
Answer:
m/(1 - .8)
Step-by-step explanation:
She read 80% of her emails, which is .8 of the total. So her unread emails would be 100% - 80% = 1 - .8
that means me can be written as:
m = (1 - .8)t
where t is the total
If we solve for t, we get:
t = m/(1 - .8)
Answer:
1
centimeters
Step-by-step explanation:
The diameter is equal to the radius × 2. We know that the radius is equal to 3/5 centimeters.
To solve this you must do
× 2.
This equals
, or 1
cm.
