Answer:
B. 136
Step-by-step explanation:
∆ABC is similar to ∆EDC, therefore the ratio of their corresponding side lengths would be the same.
Thus:
AC/EC = AB/ED
(144 - x)/x = 51/3
(144 - x)/x = 17/1
Cross multiply
(144 - x)*1 = 17*x
144 - x = 17x
144 - x + x = 17x + x
144 = 18x
Divide both sides by 18
144/18 = 18x/18
8 = x
x = 8
✔️AC = 144 - x
Plug in the value of x
AC = 144 - 8
AC = 136
Answer:
5%
Step-by-step explanation:
15/300 = 0.05
5%
The answer is: We let x be the number of bushels of grain bought each week.
The cost if Supplier A is chosen is represented by:
CA = 5.25x + 3x
The cost if Supplier A is chosen is represented by:
CB = 6.50x + 1500
If x = 500
Then,
CA = 5.25(500) + 3(500)
CA = $4,125
CB = 6.50(500) + 1500
CB = $4,750
Supplier A could cost more if the production company bought 500 bushes of grain each week. hope this helps :D
Answer:
x = -2
Step-by-step explanation:
- Subtract 5 from both sides (8x + 5 -5 = 6x + 1 -5);
- Subtract 6x from both sides (8x - 6x = 6x - 6x - 4);
- Divide both sides by 2 (2x / 2 = -4 / 2);
- Answer: x = -2
Answer:
it would be
The dependent variable is distance, the equation is y = 35x, and the dragonfly will travel 840 miles
Step-by-step explanation:
By the graph it can be seen that the distance a dragonfly can travel is dependent on the certain number of hours.
∴ Dependent variable : Distance (on y axis)
The equation of straight line is given by :-
, here m is the slope of the line and c is the initial value of y at x=0.
From the given graph, the slope of the given line passing from (0,0) and (2,70) will be :-
Also, the value of y = 0 at x=0.
∴ The equation of the given line :
At x=24,
∴ The dragonfly will travel 840 miles in 24 hours.
