Answer:
B
Step-by-step explanation:
A is not correct because 1 does not equal 1/4 +1/4.
B is correct because 1/4*1 does equal 1/5. (and all the other ones)
C is not correct because 1 does not equal 1/4*1/4
D is not correct because 1/4 does not equal 1-1/4
Answer:
She will not have enough money. She is $2.15 short.
Step-by-step explanation:
Giving the following information:
The cost of the truck is 35 plus 0.79 per mile.
<u>First, we need to structure the total cost formula:</u>
Total cost= 35 + 0.79x
x= number of miles
<u>Now, we calculate the total cost for 85 miles:</u>
Total cost= 35 + 0.79*85
Total cost= $102.15
She will not have enough money. She is $2.15 short.
If she paints 7/8=7/6 hrs
? =1 hr
1/(7/6)*7/8=3/4
Therefore she can paint 3/4 of the wall in an hour
Since y=mx+b is the slope-intercept form of a line, where m=slope and b=y-intercept, we can see that:
The y-intercept is 5 (technically the point (0,5))
The x-intercept occurs when y=0 so:
2x+5=0
2x=5
x=2.5
So the x-intercept is the point (2.5, 0)
Penny reads 14 pages in 1/3 hour.
In order for us to know the rate of penny, the number of hours per page, we need to do ratio and proportion.
14 : 1/3 = X : 1
1/3X = 14
X = 42
So there are 42 pages Penny can read in 1 hour.
