15/4 would be 3 and 3/4, 21/5 would be 4 and 1/5
Answer:
y=1/3x+0 or y=1/3x
Step-by-step explanation:
find the slope by taking two points and putting them in
y2 - y1/x2 - x1
so, (3,1) and (6,2) becomes 2-1/6-3 or 1/3 so, slope is 1/3
then to find y intercept you can put a point (6,2) and slope (1/3) into slope intercept form y - y1 = m(x - x1)
y - 2 = 1/3(x-6)
when you solve this you get y = 1/3x + 0, so y intercept is 0. you can also see. this on the graph given
A,B,C,D i.e. all statements are true!
<u>Step-by-step explanation:</u>
According to question, Lynn works as a part-time vendor selling necklaces for $15 each and bangles for $10 each. She needs to earn a minimum of $300 per week to cover her expenses. The inequality for above scenario will be :
where, x is number of necklaces & y is number of bangles.
A.
Lynn will meet her goal if she sells 12 bangles and 12 necklaces. i.e. x=12 and y=12 , putting values inequality : which follows inequality . True statement!
B.
Lynn will meet her goal if she sells 20 bangles and 6 necklaces.
putting values inequality : which follows inequality . True statement!
C.
Lynn will meet her goal if she sells 6 bangles and 12 necklaces. putting values inequality : , which follows inequality . True statement!
D.
Lynn will meet her goal if she sells 2 bangles and 18 necklaces.putting values inequality : , which follows inequality . True statement!
I did this problem last year, if I remember you do this:
64 pounds of gravel and <span>108 pounds of mulch will be the outcome
</span>
*2 1/4 will be equal to 2.25
*1 1/3 will be equal to 1.33
------------------------------------
2.25 / 1.33 = 1.7 is fine (rounded up)
------------------------------------
*ratio of gravel = 1.7: 1
------------------------------------
FOR MULCH:
1.7/2.7 from 172 you will use the outcome 0.629 * 172 to get 108.2 pounds
------------------------------------
FOR GRAVEL:
172 - 108.2 = 63.8 pounds
------------------------------------
Totals sold will be:
- 108 Pounds
- 64 Pounds
Answer:
35.54 degrees
Step-by-step explanation:
For A, we have the opposite side (5) and the adjacent side (7). We can use the inverse of tan and to tan⁻¹(5/7) to get 35.54
We use the inverse of tan because tanΘ=opposite/adjacent, and we want to find the angle. We multiply both sides by the inverse bc that's what we would do if it was a number, and then get tan⁻¹(5/7)
Hope this helps. Sorry if I added too much explaination
