Answer:
x = 12.26
Step-by-step explanation:
sin = opp/hyp
sin 50 = x/16
multiply both sides by 16
16 * sin50 = x
Use calculator
x = 12.256711089903649
Rounded
x = 12.26
Answer:
Renewable resources will always be available while nonrenewable resource can be used up
Step-by-step explanation:
Nonrenewable resource are used faster then they can replenish. They take a long time to form unlike renewable resources such as sunlight
Answer:
2172 is the total cost
Cost for tiles: 1800
cost of paint: 372
Find the surface area of the wall without floor:(for cost of paint)
40 x 15 + 40x3x2 + 15x3x2 = 600 + 240 + 90 = 930
Cost: 930/25 x 10 = 372
Find area of floor:(to find cost of tiles)
40 x 15 = 600m^2
cost: 600 x 3 = 1800pounds
add them if needed
Hope this helps
Good Luck
Answer:
y=2x-2
Step-by-step explanation:
first, let's put the line into y=mx+b form (slope-intercept form), where m is the slope (or gradient) and b is the y intercept
add 5 to both sides
x+2y=5
subtract x from both sides
2y=-x+5
divide by 2
y=-1/2x+5/2
perpendicular lines have slopes (gradients) that are negative (one is positive, another one is negative) and reciprocal (they are essentially the same number, just "flipped")
to find the slope of I2:
since -1/2 is negative, that means the slope of I2 will be 2 (2/1 is the reciprocal of 1/2 (positive version of -1/2))
so here's our equation so far:
y=2x+b
now we need to find b
because line will pass through (3,4), we can use it to solve for b
substitute 4 as y and 3 as x
4=2(3)+b
multiply
4=6+b
-2=b
therefore the equation is y=2x-2
hope this helps!!
