a checking account earns 2.5% simple interest.how much would be earned by an account with $3,400 in after 3 years

Answers

Answer:

Step-by-step explanation:

$3,400*2.5%*3=$255

To calculate the simple interest on $3,400 at a 2.5% interest rate over 3 years, the formula I = P  imes r  imes t is used, which results in $255 of interest earned in that period.

To calculate the simple interest earned by a checking account with $3,400 at a 2.5% annual interest rate over 3 years, we use the formula for simple interest:

I = P times r times t

where:

I is the interest earnedP is the principal amount (initial amount of money)r is the annual interest rate (as a decimal)t is the time the money is invested or borrowed for, in years

Let's plug in the values:

I = $3,400 times 0.025 times 3

I = $85 times 3

I = $255

So, the account will earn $255 in simple interest over 3 years.

At 10:00a.m ,pharaoh leaves his office traveling by car to deliver a book to Valerie. He stopped to eat lunch for two hours , and then returned directly to his office , arriving at 2:00pm. If Pharaohs rate going was 60mph and the rate returning was 20 mph, how far is it from pharaohs office to Valerie’s?

Answers

30 m

Step-by-step explanation:

Step 1 :

Let x be the distance traveled.

Speed taken while going is given as 60mph.

Hence time taken for the onward journey =x/60

Speed for the return journey is 20mph

Hence time for the return journey is x/20

Step 2:

Total time is from 10 m to 2 pm. Deducting the 2 hours taken for lunch, time spent for the onward and return journey is 2 hrs

=> X/60 + x/20 = 2.

Solving for x we get x = 30

Hence the distance between the office and Valerie's is 30 m

Solution:

Given that,

Alice traveled 30 miles in 3 hours

To find: Equation shows the relationship between  distance traveled (d), speed (s), and time taken (t)

The speed is given by:

[tex]Speed = \frac{distance}{time}[/tex]

From given,

Distance = d = 30 miles

Time = t = 3 hours

Thus the equation is found and speed is calculated

Is the time is takes you to run a 100-meter race function of the speed you run?

Answers

Answer:

Step-by-step explanation:

The simple answer is "yes".

The reason is that Distance = Speed (Velocity) * time taken.

d = v*t

Given that the distance is fixed, the velocity and time become inversely related such that an increase in velocity will mean that the distance is covered in a shorter time while an increase in time will mean that the distance is covered at a slower velocity.

What’s the question you’re trying to ask

Witch of these items are you most likely to buy with an installment loan ?
A. A couch
B. Groceries
C. A calculator
D. School books

Answers

A. Couch


It makes sense.

The item most likely to be bought with an installment loan is A. A couch, as installment loans are used for significant purchases paid over time. Groceries, calculators, and school books are generally less expensive and paid for upfront.

The question posed is, "Which of these items are you most likely to buy with an installment loan?" The correct answer is A. A couch. Installment loans are typically used for larger purchases that require payment over time. These include items such as furniture, cars, and appliances.

On the other hand, groceries (B), calculators (C), and school books (D) are generally more affordable and are usually paid for upfront rather than through installment loans. Installment loans often come with interest, making them more suitable for more expensive items that cannot be paid for in full immediately.

It is essential to carefully consider the necessity and the ability to repay before taking out any loan, especially for substantial purchases like a couch, to avoid financial strain.

Part 2) [tex]x=59^o[/tex]

Part 3) [tex]y=49^o[/tex]

Part 4) [tex]w=72^o[/tex]

Step-by-step explanation:

step 1

Find the measure of angle z

we know that

The sum of exterior angles in a polygon is always equal to 360 degrees

so

[tex]z^o+(z+10)^o+(z-13)^o=360^o[/tex]

solve for z

[tex](3z-3)^o=360^o[/tex]

[tex]3z=363\\z=121^o[/tex]

step 2

Find the measure of angle x

we know that

[tex]z^o+x^o=180^o[/tex] ---> by supplementary angles (form a linear pair)

we have

[tex]z=121^o[/tex]

substitute

[tex]121^o+x^o=180^o[/tex]

[tex]x=180^o-121^o=59^o[/tex]

step 3

Find the measure of angle y

we know that

[tex]y^o+(z+10)^o=180^o[/tex] ---> by supplementary angles (form a linear pair)

we have

[tex]z=121^o[/tex]

substitute

[tex]y^o+(121+10)^o=180^o[/tex]

[tex]y=180^o-131^o=49^o[/tex]

step 4

Find the measure of angle w

we know that

[tex]w^o+(z-13)^o=180^o[/tex] ---> by supplementary angles (form a linear pair)

we have

[tex]z=121^o[/tex]

substitute

[tex]w^o+(121-13)^o=180^o[/tex]

[tex]w=180^o-108^o=72^o[/tex]


x - y - 2z = 4
-x + 3y - z = 8
-2x - y - 4z = -1

The point is a solution to the system shown.

Answers

The point to the system of solution is (3, 3, –2).

Solution:

Given equations are

x – y – 2z = 4  – – – – (1)

–x + 3y – z = 8 – – – – (2)

–2x – y – 4z = –1 – – – – (3)

Let us first eliminate x from 2 equations.

Add (1) and (2)

x – y – 2z – x + 3y – z = 4  + 8

⇒ 2y – 3z = 12 – – – – (4)

Multiply equation (1) by 2 and add with equation (3)

2x – 2y – 4z – 2x – y – 4z = 8  – 1

⇒ –3y – 8z = 7 – – – – (5)

Now, Multiply equation (4) by 3 and equation (5) by 2 and add them.

6y – 9z – 6y – 16z = 36 + 14

⇒ –25z = 50

z = –2

Substitue z = –2 in equation (4), we get

⇒ 2y – 3(–2) = 12

⇒ 2y  = 12 – 6

y = 3

Substitute, z = –2 and y = 3 in equation (1), we get

⇒ x – 3 – 2(–2) = 4  

⇒ x – 3 + 4 = 4  

⇒ x + 1 = 4  

x = 3

Hence the point to the system of solution is (3, 3, –2).

if the current batch of pills is the first of the day and your goal is to produce a total of 600 what percentage of your goal will you meet after the batch is finished

Answers

Answer:

12.5% ≈ 13%

Step-by-step explanation:

The rest of the question is: There are 75 pills in the batch.

The current batch of pills is the first of the day and our goal is to produce a total of 600.

If there are 75 pills in the batch so percentage of goal completed will be

[(number of pills in the batch)/(Total pills)] * 100

[tex]\frac{75}{600}*100 = 12.5 \%[/tex]

≈ 13% to the nearest whole number

Final answer:

The percentage of the goal met after the batch is finished is 100%.

Explanation:

To find the percentage of the goal met after the batch is finished, we need to divide the number of pills produced by the goal and then multiply by 100. In this case, since the goal is 600 and the batch produced 600 pills, the percentage of the goal met would be:

Percentage of goal met = (600/600) * 100 = 100%

Therefore, after the batch is finished, 100% of the goal will be met.

Answers

Answer:

Andre scored 14 points in the game.

Step-by-step explanation:

Question :

Diego scored 9 points less than Andre in the basketball game. Noah scored twice as many points as Diego. If

Noah scored 10 points, how many points did Andre score?

Given:

Diego scored 9 points less than Andre in the basketball game.

Noah scored twice as many points as Diego.

Noah scored 10 points

To find Andre's points.

Solution:

Let Andre's score be = [tex]x[/tex] points

Then, Diego's points will be = [tex](x-9)[/tex] points

Noah's points will be = [tex]2(x-9)[/tex] points

Noah's points given = 10 points.

Thus, the equation can be given as:

[tex]2(x-9)=10[/tex]

Solving for [tex]x[/tex].

Dividing both sides by 2.

[tex]\frac{2(x-9)}{2}=\frac{10}{2}[/tex]

[tex]x-9=5[/tex]

Adding 9 both sides.

[tex]x-9+9=5+9[/tex]

∴ [tex]x=14[/tex]

Thus, Andre scored 14 points in the game.

The score of Andre and Diego is 14 and 9 points, respectively.

Given information:

Diego scores 9 points less than Andre in the basketball game.

Noah scores twice as many points as Diego.

Noah's score is 10 points.

Let x be the score of Diego.

So, the score of Andre will be x+9 and that of Noah will be [tex]2x[/tex].

Compare Noah's score to get the value of x as,

[tex]2x=10\\x=5[/tex]

So, Diego's score is 5 points.

Now, the score of Andre will be calculated as,

[tex]x+9=5+9\\=14[/tex]

Therefore, the score of Andre and Diego is 14 and 9 points, respectively.

c) 3.0

Step-by-step explanation:

1) The recursive formula that defines the given sequence is

[tex]a_1=12 \\ a_n=a_{n-1}+4.[/tex]

That means we keep adding 4 to the subsequent terms:

The sequence will be:

12,16,20,24,28,32,36,...

Therefore the seventh term is 36.

2) The sequence is recursively defined by;

[tex]a_1=20\\ a_n=a_{n-1} - 5[/tex]

This means, we have to keep subtracting 5 from the subsequent terms.

The sequence will be;

20,15,10,5,...

Therefore the fourth term is 5

3) The sequence is recursively defined by:

f(n+1)=f(n)+0.5

where f(1)=-1.5

This means that, the subsequent terms can be found by adding 0.5 to the previous terms.

The sequence will be:

-1.5,-1.0,-0.5,0,0.5,1,1.5,2.0,2.5,3.0,....

Therefore f(10)=3.0
