Answer:

X = 119

Step-by-step explanation:

Step 1: Given

Y = -5 X = 7

Y = -85 X = n

Step 2:

-85 ÷ -5 = 17

Step 3:

17 × 7 = 119

Answer:

Y = -5 X = 7

Y = -85 X = 119

n = 119

Find the measure of the indicator arc
harina [27]

Answer:

m(WXY) = 224°

Step-by-step explanation:

Measure of inscribed angle = ½ the measure of intercepted arc

Therefore:

m<C = ½*m(WXY)

112° = ½*m(WXY) (substitution)

Multiply both sides by 2

2*112° = m(WXY)

224° = m(WXY)

m(WXY) = 224°

Determine if the two lines y = 2x - 3/2 and y = -2x + 2/3 are parallel, perpendicular or neither. Explain
lorasvet [3.4K]

Answer:

Neither

Step-by-step explanation:

For two lines to be parallel, they must have the same slope. 2 and -2 are not the same. For lines to be perpendicular, their slopes must be negative reciprocals (ex 5 and -1/5) The slopes of these lines are not the same or negative reciprocals, so they are not parallel or perpendicular.

f a 42.9 ft. flagpole casts a 253.1 ft. long shadow then how long is the shadow that a 6.2ft. tall woman casts
gtnhenbr [62]
Here, Ratio of shadow to object = 253.1 / 42.9 
So, it would remain constant for all objects.
Let, the show of women = x
Then, x / 6.2 = 253.1 / 42.9
x = 253.1 * 6.2 / 42.9
x = 36.58 Ft

In short, Your Answer would be 36.58 Feet

Hope this helps!
