Answer:
The temperature of the 5th day was 3°C
Step-by-step explanation:
Mean temperature of the first 4 days = 8°C
Note that:
Mean = Sum of temperatures ÷ number of days
∴ 8 = sum of temperature ÷ 4
Therefore the sum of the first 4 days = 32
Let the temperature of the next day (the fifth day) be m
Hence,
sum of the temperatures of first 5 days = 32 + m - - - - (1)
Next, the sum of the first 5 days can be calculated from the given average of the first 5 days as follows:
Mean temperature of the first 5 days = 7
Now, you will notice that equation (1) = equation (2)
∴ 32 + m = 35
m = 35 - 32 = 3
therefore, the temperature of the 5th day was 3°C
Answer:
v=15
Step-by-step explanation:
First you multiply both v+9/3 and 8 by 3.
Like this 3 x v+9/3=8 x 3.
Then you will get v+9=24.
After you multiply both sides by 3 you subtract 9 from both sides.
v+9-9=24-9
and you will get v=15.
Answer:
1. option B is correct i.e., 
2. option D is correct i.e., 
.
3. option B is correct i.e., 
.
Step-by-step explanation:
1. Since the given equation is:
As we know that 
So, the given equation can be represented as:
2. Given equation is:
As we know that
so the given equation can be represented as:
.
3. Given equation is:
by using the properties ,
and 
= 
= 
= 
= 
= .
which is option B.
1/12 of a pound.
you must use the reciprocal of 4, 1/4, then multiply. so 1/3*1/4= 1/12
I’m pretty sure it’s 65% please correct me if i’m wrong :)
