Answer:
Step-by-step explanation:
We know i×i=i^2 which has value of -1.
We will multiply numerator and denominator by i so the denominator will no longer contain imaginary part(s).
Also multiplying by i/i does not change the value of the fraction because i/i=1.
Numerator × i gives (-5+i)i=-5i+i^2=-5i-1
=-1-5i.
Denominator × i gives (2i)i=2i^2=-2.
So the simplified version of this fraction given is:
The last simplification come from me multiplying fraction by -1/-1.
Maximum number of mangoes that Camila can buy are 5
Step-by-step explanation:
- Step 1: Find the cost of 8 apples bought by Camila.
Cost of 1 apple = $0.50
Cost of 8 apples = $0.50 × 8 = $4
- Step 2: Find the remaining amount with Camila after she bought 8 apples.
Total amount that can be spent = $7.75
Cost of apples = $4
Remaining amount = $7.75 - $4 = $3.75
- Step 3: Find the number of mangoes she can buy
Cost of 1 mango = $0.75
Number of mangoes = $3.75/$0.75 = 5
The first triangle’s area is 48.75. But since you round it to the nearest tenth, it’s 48.7.
Use the formula a=1/2bh to find the area of a triangle.
A= 1/2• 13 • 7.5
A= 6.5• 7.5
A= 48.75 —-> 48.7 square inches.
Sorry, I can only do one because of homework, but make sure to use that formula! Hope this helped.
I think it's the dividend which is what you're dividing in by the divisor in the first place.
