Answer:
8 °C
Step-by-step explanation:
Step 1: Given data
Initial temperature value (T1): -10 °C
Final temperature value (T2): -2 °C
Step 2: Calculate the change in temperature from the morning to the afternoon
To calculate the change in the temperature, we have to perform the subtraction T2 - T1.
ΔT = T2 - T1 = (-2 °C) - (-10 °C) = -2 °C + 10 °C = 8 °C
The temperature change is positive, meaning that the temperature increased.
Answer:
400 times larger
Step-by-step explanation:
Divide as follows:
4*10^6
------------ = 4*10^2 or just 400
1*10^4
Answer:
Given x = 2 and y =4
so 16+2
= 16* + 2**
= 16 + (2*4)/4
=16 + 8/2
16 + 2
=18
Step-by-step explanation:
Answer: 43°
Step-by-step explanation:
The rate of 28,000% per month is extremely big. I believe
the correct monthly rate is 2.8% (correct me if I am wrong though). Next time
kindly check the given values.
Rate is expressed in a factor of:
(1 + r)^n
where r is the rate and n is the number of months
First we calculate for the rate in a year (1 year = 12
months). We know that the rate must be constant, therefore:
rate in a month = rate in a year
(1 + 0.028)^1 = (1 + r)^(1/12)
r = 0.3929
Therefore there is an increase of about 39.29% in a year.
Then we calculate for the rate in a day (1 month = 30
days). The rate must also be constant, therefore:
rate in a month = rate in a day
(1 + 0.028)^1 = (1 + r)^(30)
r = 9.21 * 10^-4
Therefore there is an increase of about 0.092% per day.
