$37,500 should be invested in B-rated bonds and $22,500 should be invested in a certificate of deposit in order to realize exactly $6,000 in interest per year.
The total amount to be invested is $60,000. We are given two options for investing the money.The money can be invested either in B-rated bonds, which pays 13% interest per year, or in a certificate of deposit (CD), which pays 5% interest per year.Let the amount to be invested in B-rated bonds be 'x'. The amount to be invested in a certificate of deposit equals 60,000-x. The requirement is to get an exact amount of interest that equals $6000. The total interest per year = 13% of 'x' + 5% of (60,000-x).6,000 = 13x/100 + 5(60,000-x)/100.6,00,000 = 13x + 5(60,000-x)6,00,000 = 13x + 300,000-5x6,00,000 = 8x + 300,0008x = 300,000x = 300,000/8x = 37,500Now calculate the value of 60,000-x.60,000-x = 60,000-37,50060,000-x = 22,500Thus, the amount to be invested in B-rated bonds is $37,500 and the amount to be invested in a certificate of deposit is $22,500.To learn more about interest, visit :

2. Last week, Abe's carpet store sold 160 square feet of a particular carpet for $878.40. Bob's carpet store sold 85 square feet of the same carpet for $466.65
a. Is Cost proportional to area for this carpet? Show all relevant calculations and then explain your conclusion in a full sentence.
b. Answer ONE of the questions below depending on whether or not cost is proportional to area for this carpet
if cost is proportional to area, what is the cost of 118 square feet of carpet? Show your work. Use dimensional analysis
if cost is not proportional to area, which store has the better unit price for carpet explain your choice.
Consequently, the carpet's price is diversely correlated with its size. Then the cost of the carpet will be $647.82.
What are ratio and proportion?160 square feet of a certain carpet were purchased for $878.40 last week at Abe's carpet shop. The identical carpet, measuring 85 square feet, cost $466.65 at Bob's Carpet.
The cost of carpet per square foot in both cases will be
In the First case, we have
⇒ 878.40 / 160
⇒ $5.49 per square foot
In the second case, we have
⇒ 466.65 / 85
⇒ $5.49 per square foot
Consequently, the carpet's price is directly correlated with its size. Then the equation will be
Cost = 5.49 x Area
Then the cost of the carpet when the area is 118 square feet will be
Cost = 5.49 x 118
Cost = $647.82

A canoe and a paddler have a combined mass of 100.0 kg. The canoe is dropped into a river flowing from east to west. The flowing water exerts a force of 18.0 N on the canoe. The paddler exerts a force of 36.0 N [E 37.0° N]. Determine the net force on the canoe at this instant.
At this point, the canoe will be under a net force of 51.52 N.
What is the force?The total mass of a canoe and a paddler is 100.0 kg. A river that runs from east to west is where the canoe is thrown in. The power of the water current on the canoe is 18.0 N. The paddler exerts a force of 36.0 N [E 37.0° N].
The Free Body Diagram is then displayed below.
The canoe's net force would then be indicated as follows:
F = (18 + 36 cos 37°) i + (36 sin 37°) j
F = 46.75 i + 21.67 j
Therefore the force's strength will be
|F| = √(46.75² + 21.67²)
|F| = √2655.15
|F| = 51.52 N
Thus, at this point, the canoe will be under a net force of 51.52 N.

A college student realized that he was spending too much money on music. For the remaining 5 months of the year his goal is to spend a mean of $50 a month towards music. How much can he spend in December, taking into consideration that in the other 4 months he spent $30, $80, $45, and $35, respectively?
The amount he can spend in December given that he spent $30, $80, $45, and $35, respectively in the other 4 months is; x = $60.
How much can he spend in December given his spending in the last four months?It follows from the task content the intention is to spend a mean of $50 a month towards music.
On this note, it follows that the since the mean is given by the ratio of the sum of all data values and the number of data values, it follows that;
Mean = 50 = (30+80+45+35 + x)/5
where x = spending in December.
multiply both sides by 5;
(30+80+45+35 + x) = 250
x = 250 -30 -80-45-35

The trip will include 84 passengers, total. Find the 5 solutions for how many of each type of plane could be leased? (please show your work)
The solutions of the equations of the situation can be:
z = 1 , y = 5, x = 4
z= 2 , y = 3, x = 5
z=3 , y = 1, x = 6
z = 0 , y = 7, x =3
The question can be expressed as a equation
6 x + 8 y + 10 z = 84
also, x + y + z = 10
⇒ x = 10- y - z
Putting it in first equation,
6(10 - y - z ) +8y + 10z = 84
⇒ 60 +2y + 4z = 84
⇒2(y + 2z ) = 14
⇒ y + 2z = 7
Now putting
z = 1 , we get y = 5,
z= 2 , y = 3
z=3 , y = 1
z = 0 , y = 7
So, only 4 possible solutions.
Therefore, there can only be 4 possible solutions for the equations.

Using proportions, it is found that the exact value of 41% of 379 is of 155.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
The proportion of 41% of 379 is given as follows:
0.41 x 379 = 155.39.
Since 0.39 < 0.5, the exact value is rounded to 155.

Find the domain and range for the absolute value function f(x)
graphed below. Then determine where the function is increasing and/or decreasing
Step-by-step explanation:
the domain is the interval or set of all valid x values.
as we can see, the function goes continuously from all the way to the left (until all eternity to -infinity) all the way to the right (until all eternity to +infinity).
the domain is
-infinity < x < +infinity
the range is the interval or set of all valid y (function result) values.
we see, the lowest y value is -1. and then the function goes on both sides up, up, up in all eternity to +infinity.
the range is
-1 <= y < +infinity
f(x) is decreasing for

A taxi ride for the airport to your hotel costs a flat fee of $10 the moment you sit in the back seat plus $0.75 each mile plus a tip of $5 to the driver at the end of the ride. Your hotel is 24 miles from the airport and you have $30 in your pocket. Do you have enough money to make it to your hotel in the taxi, including the tip? Declare what your variable represents, write the equation or inequality that models the situation, solve for the variable showing your steps, and answer the question.
Greetings from Brasil...
We have 2 fixed fees:
→ $10 when you sit on the bench
→ $5 tip
So, fixed fees = $10 + $5 = $15
The rate that varies would be the distance traveled. The fee will be $0.75 per mile moved. In this case we can write that:
C = 0.75M + fees
C = 0.75M + 15let
C = cost
M = mile(s)
for 24 miles, M = 24, then
C = 0.75M + 15
C = 0.75 · 24 + 15
C = 18 + 15
C = $33
With $30 it will not be possible to make this trip, as the total cost would be $33
One solution or alternative would be to reduce the tip amount. Instead of $5, pay only $2 of tip.
We can rewrite the cost expression involving a variable for the tip:
C = 0.75M + T + 10
let T = tip
For the exercise example.... The distance (M) its 24 miles and the value of C has to be what I have in my pocket: 30.... then M=24 and C=30
C = 0.75M + T + 10
30 = 0.75 · 24 + T + 10
30 = 18 + T + 10
30 - 18 - 10 = T
T = 2
Is it possible to do this ride if you pay only $2 tip

D: 55.5=19m+555 point 5 is equal to 19 m plus 5
Answer:
b
Step-by-step explanation:
Trust me
The equation that could be used to determine, m, is 5m = 55.5 - 19. The correct option is C. m = (55.5 - 19)/5
Writing equationFrom the question, we are to determine the equation that could be used to determine, m, the average number of miles she would have to ride to meet her goal
From the given information,
"Arianys wants to ride her bicycle 55.5 miles"
and
"She has already ridden 19 miles"
Thus,
The number of miles she needs to ride more is
55.5 miles - 19 miles
= 36.5 miles
If m is the average number of miles she would have to ride for 5 more days to complete her goal,
Then, we can write that
m = 36.5/5
OR
m = (55.5 - 19)/5
Hence, the equation that could be used to determine, m, is 5m = 55.5 - 19. The correct option is C. m = (55.5 - 19)/5
