Bekkah's savings account earns 2.75% interest per year.
If she put $12,500 into the savings account, how much interest is earned in a year, in dollars?
Answer:
343.75 dollars
Step-by-step explanation:
First I like to solve for the value of 1% which is 125 then we solve for .10% which is 12.5 then we solve for .01% which is 1.25 I find this helpful because now we have the unit amount for each percent we use in this equation now to multiply we have .05 percent so we take our 1.25 value for .01 percent and multiply by 5 which give us 6.25 then we do .7% we take our .1 percent value and multiply 12.5 x 7 give us 87.5 then we do the 2% we take our 1 percent value and multiply by 2 125 x 2 give us 250 now we add it all together 250+87.5+6.25 = 343.75 I hope this help you out :)

Answer:
W = 8.2 cm
Step-by-step explanation:
The perimeter formula is P = 2W + 2L and here the perimeter is 65.6 cm.
Thus, 65.6 cm = 2W + 2L. Substituting 3W for L, we get
65.6 cm = 2W + 2(3W) = 8W.
Solving for W by dividing both sides by 8, we get W = 65.6 cm / 8, or
W = 8.2 cm

How much space is inside the steps?
Answer:
The answer is 0.045
Step-by-step explanation:
1. Use this formula V=lwh
0.5 x 0.4 x 0.15 = 0.03
That is the volume of the lower prism
2. Do V=lwh again for the volume of the upper prism
0.5 x 0.15 x 0.2 = 0.015
3. After that add both of them up together
0.015 + 0.03 = 0.045

the formula for a straight line is y=mx+b where m is your slope (so 2 in this case) and b is your y-intercept (your initial value is what I think they call it here)
Step-by-step explanation:
I already explained this in the "ask [insert name here] about this question" thing, but out of the goodness of my heart I can do it once more. Just take random 2 coordinates and take the difference of the y values and divide it by the difference of the 2 x coordinates. Simple! Any more questions just ask me on this or DM me

In Science class, Mrs. Olson had 30.6 pounds of metamorphic rock. Mrs. Olson had to divide the rocks into 9 different containers for a class assignment. If the rocks are equally divided into 9 different containers, how many pounds of rock will be in each container?
The answer is 3.4 because 30 can’t be divided equally into 9, reason being that 9 x 30 = 270 which doesn’t make sense, so you have to divide 30 equally into 9 parts then turn it into a ratio.
