80÷12= 6 2/3
12×12×12×12×12×12=72
so 12 goes into 80 evenly 6 times, but there is a remainder so you have to include it
80-72=8
so that leaves you with 8/12 which is 2/3 when simplified
now you have 6 + 2/3 = 6 2/3
Answer:
Step-by-step explanation:
To solve this problem, you need to set up a proportion. If she jogs 6 miles per hour, then this can be written as . If there are 5280 feet in a single mile, then first we multiply the two proportions like this:
The two 'mile' values cancel each other out, so then just multiply . This equals to 31680 feet per hour. Now let's convert to seconds.
, or 360 seconds every hour. Since hours are much longer than seconds, multiply 31680 by the reciprocal of 360, so that it makes sense.
She runs 88 feet per second.
a right angle is 90°, or 1/4 of a circle.
3/5 * 1/4 = 3/20
radian measure is the length of the circumference of this part of the circle.
a full circumference of a circle would be 2*pi*r, also expressed as 2 rad * r
now let's multiply the full thing with the 3/20 from earlier to just get the desired fraction:
6/20 rad * r
<u>= 3/10 rad * r</u>
of course a solution in cm or inch still depends on the radius here, wich could be just plugged in at will
Answer:
B,C&F
Step-by-step explanation:
-2x>-4
multiplied by -1 gives 2x<4
And you devide both sides by 2 you get x<2
The numbers smaller than 2 in your options are 1,1.5 and -2
