Answer:
Step-by-step explanation:
log 31.3= 1.49554433755 (round to 1.496)
ln square root of 7= 0.97295507452 (round to .973)
Answer:
The answer is 207 miles per hour
Step-by-step explanation: You can find this answer by taking 332 and converting it to a fraction and then multiplying it by 5/8. That would look like this 332/1 X 5/8 = x. Then you multiply then numerators, then denominators and simplify the fraction. Next you can divide the numerator by the denominator. And once you have this you round to the nearest whole number.
Hope this helps.
Area=legnth times width
legnth is 1 less than 2 times width
l=legnth
w=width
l=-1+2w
l=2w-1
area=lw
area=45
subsitute
45=lw
45=(2w-1)w
distribute
45=2w^2-w
subtract 45 from both sides
0=2w^2-w-45
factor because if we have xy=0 and we factor we can assume that x and/or y=0 so
trial and error factor
0=(2w+9)(w-5)
set each to zero
0=2w+9
subtract 9
-9=2w
divide 2
-4.5=w
impossible since width cannot be negative so discard
w-5=0
add 5 to both sides
w=5
true
subsitute
l=2w-1
l=2(5)-1
l=10-1
l=9
w=5 cm
l=9 cm
5,12,13 is a triple, i.e. integer values of a right triangle. It's Perimeter is 30.
Then <= 120 yields 4 times this triple, yielding another triple of 20,48,52
