So k=1000 like 4k=4 000 so 6/7 of a thousnad =0.857142857 so times 6=0.857142857
Answer:
every 1/4 inch on the map is 1 mile.
You need to find the number of 1/4 inches there are in 3 1/2 inches.
There are four 1/4 inches per inch.
3 x 4 = 12
There are two 1/4 inches in 1/2 inch.
12+2 = 14
The cities are 14 miles apart.
Answer:
A. 4x²+20x+25
Step-by-step explanation:
Because of PEMDAS, you calculate the value inside of the parenthesis first, so you expand [2x+1-(4x+6)]:
2x+1-4x-6 = -2x-5.
Then apply the exponent:
(-2x-5)² = (-2x-5)(-2x-5) = 4x²+10x+10x+25 = 4x²+20x+25
Answer:
45 cm
Step-by-step explanation:
Let x represent the length of the longer leg. Then the hypotenuse is x+8 and the shorter leg is x-17. The Pythagorean theorem gives the relation between these values as ...
(x +8)^2 = x^2 +(x -17)^2
x^2 +16x +64 = 2x^2 -34x +289 . . . . eliminate parentheses
0 = x^2 -50x +225 . . . . . put in standard form
0 = (x -45)(x -5) . . . . . . . . factor
Solutions to this equation are x=5 and x=45. The value of x must be greater than 17, so the useful solution is x=45.
The length of the longer leg of the triangle is 45 cm.
- line CD is perpendicular to segment AB
- point M is the midpoint of segment AB
