Answer:
2115
Explanation:
To evaluate the expression (60−6)×(13)3+27÷3 we use BODMAS
BODMAS is an acronym/rule in mathematics that dictates the order we should solve mathematical operations such as the above.
BODMAS stands for bracket first, order or of, division, multiplication, addition and then lastly subtraction
To solve the expression using BODMAS, we solve the brackets first
(60−6)×(13)3+27÷3 =54×39+27/3
Then division
=54×39+9
=2106+9
Then addition
=2106+9=2115
Answer=2115
Answer:
25
Step-by-step explanation:
Since they were born on consecutive years, their ages are 4 consecutive whole numbers. Let the lowest age be x. Then the other ages are x + 1, x + 2, and x + 3.
Now we add the 4 expressions and set the sum equal to 94.
x + x + 1 + x + 2 + x + 3 = 94
4x + 6 = 94
4x = 88
x = 22
The youngest one is 22.
The oldest one is
x + 3 = 22 + 3 = 25
Answer: 25
Answer: Choice D
Explanation:
The increase of 9.8% rounds to 10% when rounding to the nearest ten
An increase of 10% would use the multiplier 1.1
Think of it like saying 1 + 0.10 = 100% + 10%
Similarly, the 5.1% rounds to 5% and an increase of this amount will use the multiplier 1.05
So if we started with 20 items, then 20(1.1)(1.05) is the expression that estimates an increase of 10% followed by an increase of 5%. The order doesn't matter (so you could increase by 5% first, then 10% later).
