Answer:
1 in : 50 mi . . . or . . . 1 : 3,168,000
Step-by-step explanation:
Dividing the areas by 10, you get 1 square inch corresponding to 2500 square miles. Those areas are equivalent to 1 inch square and 50 miles square. Hence the scale factor is 1 inch : 50 miles.
Sometimes map scales are expressed as a dimensionless ratio. The number of inches in 50 miles is
... (50 mi)×(5280 ft/mi)×(12 in/ft) = 3,168,000 in
so, the map scale can be expressed as 1 : 3,168,000.
Answer:
b
Step-by-step explanation:
Given:
Tom's earnings: x
Jan's earnings: 2x - 150
Total earnings: 1380
x + 2x - 150 = 1380
3x = 1380 + 150
3x = 1530
3x/3 = 1530/3
x = 510
Tom's earnings: x = 510
Jan's earnings: 2x - 150 = 2(510) - 150 = 1,020 - 150 = 870
total earnings: 1,380
510 + 870 = 1,380
1,380 = 1,380
Answer:
8.125 inches
Step-by-step explanation:
Ok so basically what you needed to do was this
Find out what was the value like this 3 1/4 = 3.25 and 2 1/2 = 2.5
Then you will do
3.25 x 2.5 and get your answer
8.125
There you go! Have a Wonderful Day
Answer:
C
Step-by-step explanation:
To find the x-intercept, set y to equal 0 and solve for the equation 0=-2x-2.
2=-2x
x=-1
x-int: (-1,0)
This eliminates choices B and D.
To find the y-intercept, set x to equal 0 and solve for y.
y=-2(0)-2
y=-2
y-intercept:(0,-2)
The only choice with both these values is C.
