Need help please would really be greatful

Rainbow [258]

Answer:

122°

Step-by-step explanation:

The formula for finding the sum of all angles in a polygon is:

(n-2) * 180°

n is the number of angles

Here n = 7, so the sum of all angles is

(7-2) * 180° = 900°

x = 900 - 128 - 130 - 120 - 115 - 145 - 140 = 122°

Make me the brainliest ;)

Sam is observing the velocity of a car at different times. After three hours, the velocity of the car is 51 km/h. After five hou

bija089 [108]

It's not obvious here, but you're being asked to find a linear equation for the velocity of the car, given two points on the line that represents this velocity.

Find the slope of the line segment that connects the points (3 hr, 51 km/hr) and (5 hr, 59 km/hr). Graph this line. Where does this line intersect the y-axis? Find the y-value; it's your "y-intercept," b.

Now write the equation: velocity = (slope of line)*t + b

The units of measurement of "slope of line" must be "km per hour squared," and those of the "y-intercept" must be "km per hour."

Part B: Start with the y-intercept (calculated above). Plot it on the vertical axis of your graph. Now label the horizontal axis in hours: {0, 1, 2, 3, 4, 5, 6}. Draw a vertical line through t=6 hours. It will intercept both the horiz. axis and the sloping line representing the velocity as a function of time. Show only the part of the graph that extends from t=0 hours to t=6 hours.

A map

Bess [88]

The scale of the map from inches to miles is 1 inch : 9 miles

<h3>How to determine the scale of the map from inches to miles?</h3>

The given parameters are:

The actual distance of the cities apart = 36 miles
The scale distance of the cities apart = 4 inches

The scale of the map from inches to miles is represented as:

Scale of map = The scale distance of the cities apart : The scale distance of the cities apart

Substitute the known values in the above equation

Scale of map = 4 inches : 36 miles

Divide both sides of the ratio by 4

So, we have:

Scale of map = 4/4 inches : 36/4 miles

Evaluate the quotient

Scale of map = 4/4 inches : 9 miles

Evaluate the quotient

Scale of map = 1 inch : 9 miles

Hence, the scale of the map from inches to miles is 1 inch : 9 miles
