Answer:

95 degrees

Step-by-step explanation:

Angle S is 95 so arc QR = 95×2 = 190

Total arc is 360 degree

Now to find arc QS

arc QS + arc SR + arc QR =360

arc QR + 75 + 190 =360

arc QR = 360- 265

arc QR = 95 degrees

A highway is going to be built around a city. The highway will be in the shape of a perfect circle, and its total length will be

Molodets [167]

Answer:

The area that is surrounded by the highway on the billboard is approximately 89.34 square meters

Step-by-step explanation:

The given parameters are;

The length of the circle shaped highway = 251.2 km

The scale of the map of the bus routes along the highway = 1:7,500

The circumference of a circle, C = 2·π·r = The length of the perimeter of the circle

Therefore, we have;

The circumference of the highway = The length of the circle shaped highway = 251.2 km

The circumference of the highway, C = 251.2 km = 2·π·r

The radius of the circular highway path, r = 251.2 km/(2·π) ≈ 39.994217 km

The area of a circle, A = π·r².

The area of the highway = π·r² = π × (39.994217 km)² ≈ 5,025.09492434 km.²

Given that the scale of the map = 1:7,500. we have;

The scale of the area = (1:7,500)² = (1:56,250,000)

The size of the drawing, 5,025.09492434 km.²/(56,250,000) = 0.00008933502 km² = 89.33502 m.²

Therefore, the area that is surrounded by the highway on the billboard, rounded to the nearest hundredth of a square meter ≈ 89.34 m.²

Answer:

Step-by-step explanation:

We can solve this particular problem entirely by elimination. First, notice, that our inequality simply says the left side is less than the right, not less than or equal to. If it were less than or equal to the value on the right, it would include all of the points on the boundary line, and we'd indicate this with a solid line. In our situation, the left side is never equal to the right, so we'd use a dotted line to draw our boundary line. Only B and D fit the bill.

So between B and D, which one represents $4y+8$ ? Well, setting the two sides equal to each other, we'd get the equation for a line. If (x, y) is a point on that line, then, what does mean when we say the side with y on it is less than the side with the x on it? It means we'd have to decrease the y value of a point on the line, which would give us a point below the line. So our graph has to show every point below the line 4y + 8 = -3x, and the only answer that represents this situation is D
