Hey there!
If you ever see the word "is" in a story problem, it means that there is an equal sign there. Let's apply that to this.
23800 =(is) 0.34i (income)
Now, we can solve for i by dividing.
23800/0.34= 70,000
Therefore, the annual income is $70,000.
I hope this helps! Have a great day!
Answer:
57.5 students
Step-by-step explanation:
Given that
The 30% students would be arrived by private car
So 15% would be travelled by taxi
And, the remaining i.e. 55% would be walk to school
Since the population of the school is 230
So by car, the students would be
= 230 × 0.30
= 69
By walk, the students would be
= 230 × 0.55
= 126.50
Now the more students would be
= 126.50 - 69
= 57.5 students
Answer:
a) 2.5×2.5×2.5-1.4×1.4×1.4=12.881
b) (2.5)2+2.5×1.4+(1.4)2=31.5
Step-by-step explanation:
yuh multiple 2.5 three times and subtract 1.4 multiple three times. 2.5×2.5×2.5-1.4×1.4×1.4
15.625-2.744=12.881.
b) when opening bracket Yuh multiple the number in the bracket by the number outside the bracket. when bracket is open Yuh can now add, multiple to obtain your answer please
(2.5)2+2.5×1.4+(1.4)2
5+2.5×1.4+2.8
7.5×4.2=31.5
Answer:
