Answer:
1,000
Step-by-step explanation:
In 1990, 500 donuts were sold per day. In the year 2000 the number of donuts sold went up by 200 to reach 700 donuts per day. Since we are to assume it's a linear relationship, it would mean that every ten years the number of donuts sold would go up by 200/day. In 2010 the shop would be selling 900 donuts per day. So, in 2015, The shop would be selling 1,000 donuts per day since only 5 years had passed since 2010 and after 5 years it would only go up by 100/day.
If they do not have a line of best fit this may be because there is no correlation
1.) 3(5 - 2x) = -2(6 - 3x) - 10x
15 - 6x = -12 + 6x - 10x
-6x - 6x + 10x = -12 - 15
-2x = -27
x = -27/-2 = 13.5
x = 13.5
2.) 1/4x - 2/5x = 39
-3/20x = 39
x = (39 x 20)/-3 = -260
x = -260
3.) 115 = 20 + 2.5x
2.5x = 115 - 20 = 95
x = 95/2.5 = 38
x = 38
4.) 0.7x - 0.2 = 8.3x + 7.2
8.3x - 0.7x = -0.2 - 7.2 = -7.4
7.6x = -7.4
x = -7.4/7.6 = -37/38
x = -37/38
The option which is not a possible distance for the flight from Haiti back to Cuba is 43, because that number is far too low to be a possible option. The correct answer should be somewhere around 500km, which means that the remaining options are close to it, whereas 43 is not.
Given:
In the given figure, , WS = 5, WR = 4x+3, RT=7x+3 and VT=8.
To find:
The measure of WR and RT.
Solution:
In triangles WRS and TRV,
(Given)
(Vertically opposite angles)
(AA property of similarity)
We know that the corresponding sides of similar triangles are proportional. So,
Isolate the variable x.
Divide both sides by 3.
Now,
And,
Therefore, the measure of WR is 15 units and the measure of RT is 24 units.
