Answer:
Explanation:
1) You can draw a right triangle where the distance of 17,000 miles from the horizon of Earth is leg, perpendicularto the radius of the Earth, and such radius is the other leg, 4,000 miles.
2) By the construction of the right triangle, the hypotenuse is the sum of the height of the satelite (unknown, x) plus the radius of the Earth (4,000) = x + 4,000.
3) Now, you can use Pythagora's theorem:
- (x+4,000)² = 4,000² + 17,000²
- (x + 4,000)² = 305,000,000
- (x + 4,000) = 17,464 (take only the positive root)
- x = 17,464 - 4000 = 13,464
Remember to include the units: miles.
Answer: 13,464 miles.
If we know that Sophie already has $14 saved up and that she plans to save $5 each week, we can find out how many weeks until she can get her jacket.
<u>$14 already saved up</u>
14 + 5 = $19 → first week
19 + 5 = $24 → second week
24 + 5 = $29 → third week
29 + 5 = $34 → fourth week
34 + 5 = $39 → fifth week
39 + 5 = $44 → sixth week
44 + 5 = $49 → seventh week
49 + 5 = $54 → eighth week
54 + 5 = $59 → ninth week
59 + 5 = $64 → tenth week
Therefore, it will take Sophie 10 weeks to save up enough money for her new jacket.
2 is Multiply.
you multiply 5 on each side of the equation to isolate the variable (x)
