Step-by-step explanation:
multiplying both numerators and denominators of both fractions by any number to get equivalent fractions. let us multiply by 20 so
-2/5 = -40/100 and
2/5 = 40/100
so rational numbers between them
-39/100, -38/100,-37/100.........-3/100,-2/100,-1/100,0,1/100,2/100,3/100................37/100,38/100,39/100

ANSWER
(C)38.16
EXPLANATION
The acute angle given in the right triangle is 27°.
The side length adjacent to the 27° angle is 34 units.
The side length we want to find is x units, which is the hypotenuse of the right triangle.
We use the cosine ratio to obtain:


Solve for x,


to the nearest hundredth.
The answer is 67.5. The other part I do not understand.
I think the number is 290.
*There's 2 hundreds
*9 is 9 more than 0
Answer: Mary covers less distance for 320 m
Step-by-step explanation:
Psqere=4a
Prect=2(a+b)
anna=4*4a (a=90m)
Anna=16*90=1440m
Mary=4*2(a+b)=8(a+b)=8*(80+60)=8*140=1120 m
anna-Mary=1440-1120=320m
