Let's say if both work together, they can do it in "t" hrs
so, if Latoya can do it by herself in 14hrs, how much can she do in 1hr? well, she can do only 1/14 of the total
if Lisa can do it in 10hrs by herself, how much can she do in 1hr? well, 1/10 of the total
now, let's add their rate together, keeping in mind, their rate added, will be doing in 1hr only 1/t of the total work
thus
so, they'd do it in 5hrs and 5/6 of an hour, which is just 50mins, so, 5hrs and 50mins
A and C is 59 because 1 line is 180 degrees so you add 75 and 46 and you get 121 and then do 180 - 121 and you get 59
Answer:
angle edf is 70
Step-by-step explanation:
triangle angles always add up to 180. So if you have 40 degrees at angle e already, 180-40 = 140
since side DE and side EF are congruent, that means its an isosceles triangle. One rule for that type a triangle is that the two base angles are equal. So you can just do 140/2 = 70
hope that helps!
Rightttt! I hate it but I have no idea haha
Answer:
I'm not sure how to interpret "y = 3√x+1-2."
I'll assume y = 3 - 2
Step-by-step explanation:
Use the free online app DESMOS. Either enter the equation, or make a table of individual points and plot them as ordered pairs.
<u>GRAPH:</u> See attached image
<u>PLOT:</u> Calculate a few points, mark them on the graph and then connect the dots. I selected a few values of x and calculated y from the equation. Each calculation provides a (x,y) ordered pair which can be marked on the graph and the dots are then connected. Note that x values less than -1 result in a value of y that includes i, an imaginary number. So the graph ends abruptly at that point.
