Answer:

$(-\infty,\frac{25}{24}]$

Step-by-step explanation:

Assuming $i$ is a variable:

$4i-4(i+2)\geq6(8i-8)\\\\4i-4i+2\geq48i-48\\\\2\geq48i-48\\\\50\geq48i\\\\\frac{50}{48}\geq i\\ \\\frac{25}{24}\geq i\\ \\i\leq\frac{25}{24}\\ \\(-\infty,\frac{25}{24}]$

The area of a trapezoid is

horrorfan [7]

Answer:

<h2>The answer is 15cm</h2>

Step-by-step explanation:

Let b be the length of the second parallel side

Area of a trapezium is given by

$A = \frac{1}{2} (a + b)h$

where

h is the height

a and b are the parallel sides

From the question

Area = 230 cm²

height = 20cm

one of parallel side / a = 8 cm

Substitute the values into the above formula and solve for b

That's

$230 = \frac{1}{2} ( 8 + b) 20$

Reduce the fraction with 2

That's

$230 = (8 + b) \times 10$

Expand the terms

That's

$230 = 80 + 10b$

$10b = 230 - 80 \\ 10b = 150$

Divide both sides by 10

We have the final answer as

Hope this helps you

Find the value of k given that the line through (k,2) and (7,0) is perpendicular to the line y=x-28/5

Tanzania [10]

Y = x - 28/5. The slope here is 1. A perpendicular line will have a negative reciprocal slope. So our perpendicular line will have a slope of -1.

slope = (y2 - y1) / (x2 - x1)
(k,2)....x1 = k and y1 = 2
(7,0)...x2 = 7 and y2 = 0
sub
slope = (0 - 2) / (7 - k)
slope = -2 / ?......now if we want the slope to be -1..that means the number where the question mark is has to be 2....for that to happen, k has to be 5...because 7 - 5 = 2.

so ur answer is : k = 5

Use proportions.
214/236=x/100(100 because it's a percentage.
cross multiply:
23600=214x
solve for x:
x= 11.3(rounded)
