Ascience teacher ordered $3980 worth of microscopes and dissection kits for the new science lab a total of 38 microscopes and 47 dissection kits were ordered a microscope cost four times as much as a dissection kit write a system of linear equations that represent the situation what is the cost of each item

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

their is no graph showing

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
