Levi borrowed $7129 at 4% simple interest for 6 months. How much will the interest amount to? What is the total amount that Levi

rodikova [14]

Answer:

Interest will amount to $142.58

Total amount Levi will have to pay back at the end of 6 months=$7271.58

Step-by-step explanation:

Simple interest=principal×rate×time

Principal=$7129

Rate=4%=0.04

Time=6 month=0.5 year

Simple interest=principal×rate×time

=$7129×0.04×0.5

=$142.58

Interest will amount to $142.58

Total amount Levi will have to pay back at the end of 6 months

=principal + total interest

=$7129+$142.58

=$7271.58

Work out the perimeter

Tasya [4]

Answer:

46CM

Step-by-step explanation:

Perimeter = S + S + S + S + S + S + S +S

Perimeter = 9 + 7 + 8 + 5 + 5 + 8 + 2 + 2

Perimeter = 46 cm

The other 4 measurements:

5 is from the other side labelled 5 this is because they are equal.

8 is from the other side labelled 8 this is because they are equal too!

The twos are from the difference between 9 and 7.

Rajan needs 1 liter of 15% hydrochloric acid solution for an experiment. He checks his storage cabinet, but he only has a 5-lite

yarga [219]

Answer:

Rajan must use 0.75 liters of 5% hydrochloric acid solution and 0.25 liters of 45% hydrochloric acid solution.

Step-by-step explanation:

Let us assume that, x liters of the 5% hydrochloric acid and y liters of the 45% hydrochloric acid solutions are combined.

As Rajan need total of 1 liter of solution, so

$x+y=1$

i.e $x=1-y$ --------------------1

As Rajan needs 5% hydrochloric acid and 45% hydrochloric acid to make a 1 liter batch of 15% hydrochloric acid, hence acid content of the mixture of two acids will be same as of the final one, so

$0.05x+0.45y=1\times 0.15$

i.e $5x+45y=15$ -------------2

Putting value of x from equation 1 in equation 2,

$\Rightarrow 5(1-y)+45y=15$

$\Rightarrow 5-5y+45y=15$

$\Rightarrow 5+40y=15$

$\Rightarrow 40y=15-5=10$

$\Rightarrow y=0.25$

Putting the value of y in equation 1,

$x=1-0.25=0.75$

Therefore, Rajan must use 0.75 liters of 5% hydrochloric acid solution and 0.25 liters of 45% hydrochloric acid solution.

Casey bought sandwiches and bags of chips. Each sandwich cost three times asmuch as a bag of chips. She bought 5 sandwiches for

Lerok [7]

Answer:

Casey Bought 6 bags of chips

Step-by-step explanation:

If each sandwich costs 3 times the amount of a bag of chips and the sandwich is 6 dollars, the chips are 2 dollars. Casey bought 5 sandwiches and spent $30 dollars on sandwiches. Since the total was $42 dollars you have $12 dollars left to get your total of $42. 2x6 = 12 so therefore Casey bought 6 bags of chips.
