Money with Nathan in his savings account = $40
Rate of interest per annum = 5%
We know that :
In this case :
Principal = $40
Rate = 5%
Time = 1 year
Simple interest he will earn in 1 year :
Amount = Principal + Interest
Amount Nathan has to pay at the end of one year :
Thus, at the end of 1 year Nathan has to pay $42.
Therefore, simple interest Nathan will earn in 1 year = $2
Answer:
C. In 2001, the temperature was 83°F.
Step-by-step explanation:
79 is 4 less than 83.
The temperature in 2001 was 83 °F.
There are many ways you can factor this.
1. 8(3p+8)
2. 4(6p+16)
3. 2(12p+32)
Answer:
Yes, 19.3649167 < 20
Step-by-step explanation:
Do the Pythagorean theorem to figure out the height.
35^2 + x^2 = 40^2
1225 + x^2 = 1600
x^2 = 375
x = 19.3649167
There is a very simple way of dealing with percentages.
"increase" means add
"decrease/discount/reduce" means subtract
Now, we know that the original price is 100%.
100% = 1 (like 50% = 0.5)
So if an object's price is x and it is 20% off, we get:
100%x - 20%x
Taking x common,
x(100% - 20%)
= 0.8x
Therefore, if we fist add/subtract the percentages we can multiply directly with the original to get the answer. This is as follows:
5] Increase 101 by 16%
1 + 0.16 = 1.16
So the answer is:
101 * 1.16
= 117.16
6] Decrease 36 by 21%
1 - 0.21 = 0.79
The answer is:
36 * 0.79
= 28.44
7] Let original price be x, we know it is 35% off
1 - 0.35
= 0.65
0.65x = 13
x = 20
