Answer:
17. 290a for pizza / 5b for celary / 290a+5b=total calorie intake
18. 8.50a for adult tickets / 5.50c for children tickets / 8.50a+5.5c=total for tickets
Answer:
f = 10/3
Step-by-step explanation:
-15 + 6f = 5
-15 + 15 + 6f = 5 + 15
6f = 20
6f/6 = 20/6
f = 20/6 = 10/3 = 3.333...
<u>Answer</u>
18.5 m²
<u>Explanation</u>
The figure is a sector of angle 85° and of radius 5 m.
The area = θ/360 × π × r²
= 85/360 × 3.14 × 5²
= 18.5347
The answer to one decimal place is 18.5 m²
|a+bi| = √(a² + b²)
-4-√2 i -> take a = -4 and b = -√2
|-4-√2 i| = √[ (-4)² + (<span>-√2)² ]
= </span><span>√[ 16 + 2<span> ]
</span></span><span>= √[ 18 ]</span> = <span>√[ 9 * 2 ]
= 3√2
the absolute value is 3√2</span>
Because if X is ten then the equation is complete
