The interest received on a savings account varies directly with the amount deposited. Daniel received $55.35 in interest on $123
astra-53 [7]

Answer:

90.00

Step-by-step explanation:

because all they did was add a couple of hundred that would not boost the 55.35 all the way to the thousands so A is not right It's not B because 55.35 is more than 34.04 so it's not B it's not D because 44,444.44 is just way too high it's even higher than option A.

East of Star, the railroad tracks intersect highway 23o as shown above. If 1=133 , find 2.
GrogVix [38]
Hi there.

These two angles sum up to be 180 degrees, so they are supplementary angles. Now, since these angles sum up to 180 degrees (to form a straight line), we only have to subtract 133 from 180 to find angle 2's measurement.

180 - 133 = 47

Angle 2's measurement is 47 degrees.

Voila! 

I hope this helps! Have a great day. :)

Two crews working toward each other are 6.75 miles apart one crew paves 1.3 miles of highway per day and the other paves 1.4 mil
andre [41]
One crew is doing 1.3 miles daily, the other is doing 1.4 miles daily, so both together are doing 1.3 + 1.4 miles daily, namely 2.7 miles.

now, they are 6.75 miles apart, how many days will it be at a rate of 2.7 miles per day, that 6.75 miles will be done?    \bf \cfrac{6.75}{2.7}  days
