Sarah invested $3,800 in an account paying an interest rate of 3.6% compounded daily. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 15 years?

Answers

Answer:

6500

Step-by-step explanation:

A=P(1+nr)nt

Compound interest formula

P=3800

r=0.036

t=15

n=365

P=3800r=0.036t=15n=365

Given values

A=3800 (1+0.036 365)

365(15)

A=3800(1+365 0.036)

365(15)

Plug in values

A=3800(1.0000986301)     5475

A=3800(1.0000986301)

5475

Simplify

A=6520.65243954

A=6520.65243954

Use calculator

A≈6500

A≈6500

Round to nearest hundred

The amount in account after 15 years will be $6500

What is compound interest ?

Compound interest is the interest you earn on interest.

Given that, Sarah invested $3,800 in an account paying an interest rate of 3.6% compounded daily.

Compound interest formula;

A = P(1+r/n)^nt

We have,

P = 3800

r = 0.036

t = 15

n = 365

P = 3800 r = 0.036 t = 15 n = 365

Putting the values and on simplification, we get,

A = 3800(1+0.036 365)365(15)

A = 3800(1+365 0.036)365(15)

A = 3800(1.0000986301)5475

A = 3800(1.0000986301)5475

A = 6520.65243954

A = 6520.65243954

A ≈ 6500

A ≈ 6500

Hence, The amount in account after 15 years will be $6500

Step-by-step explanation:

All you have to do is solve the equation.

2.25x + 5 = 45.50 (subtract 5 on each side)

2.25x = 40.50 (divide by 2.25 on both sides to get the x alone)

x = 18

40.50/2.25 = 18

Answer:

If she tipped the driver $5, we need to remove that from the equation. So it's now $40.5.

Now to find the answer all we need to do is divide 40.5 by 2.25, which is 18.

Given mn, find the value of x.

Answers

Answer:

x = 32 degrees

Step-by-step explanation:

since there is a line intersecting both of the lines you would do the opposite number to solve the problem. basically what i am trying to say is.

A straight line equals 180 degrees

and the given angle is 148 degrees

so just subtract.

180 degrees - 148 degrees = 32 degrees

so x = 32 degrees

to see if it is reasonable, look at the angle

if you look you can see that it is an acute angle

so, since 32 degrees is an acute angle, the answer is also reasonable.

so like i said,

x = 32 degrees

The interior angles of parallel lines and a transversal are the angles between the parallel lines.

The value of x is 32 degrees

Alternate interior angles of a parallel line add up to 180 degrees.

So:

[tex]\mathbf{148 + x = 180}[/tex]

Subtract 148 from both sides

[tex]\mathbf{148 - 148+ x = 180 - 148}[/tex]

Evaluate like terms

[tex]\mathbf{x = 32}[/tex]

Hence, the value of x is 32 degrees

Two secant segments are drawn to a circle from a point outside the circle. The external segment of the first secant segment is 8 centimeters and its internal segment is 6 centimeters. If the entire length of the second secant segment is 28 centimeters, what is the length of its external segment?

Answers

Given:

Two secant segments are drawn to a circle from a point outside the circle.

External segment of the first secant segment = 8 centimeters

Internal segment of the first secant = 6 centimeters.

Entire length of the second secant segment = 28 centimeters.

To find:

The length of its external segment.

Solution:

Let x be the length of its external segment.

Entire length of the first secant segment = 8+6 = 14 centimeters.

If two secant segments are drawn to a circle from a point outside the circle, then product of entire length of first secant and external length of first secant is equal to product of entire length of second secant and external length of second secant.

[tex]14\times 8=28\times x[/tex]

[tex]112=28x[/tex]

Divide both sides by 28.

[tex]\dfrac{112}{28}=x[/tex]

[tex]4=x[/tex]

Therefore, the length of external segment of second secant is 4 centimeters.

In 2005, the UT Longhorns scored 15 times to win the Big 12 Championship Game 70-3. All of their points came from touchdowns (6 points each) and extra point kicks (1 point each). How many touchdowns and extra points did the Longhorns have in that game? (For the purposes of this problem, touchdowns and extra point kicks count as separate "scores".

Answers

Answer:

The number of touch downs = 11

The number of extra points = 4

Step-by-step explanation:

The number of times UT Longhorns scored = 15 times

The composition of the scores = Touch down and point kicks

The points with which UT Longhorns won the game = 70-3

The points that came from each touch down = 6 points

The points that came from each point kick = 1 points

We have;

The number of touch downs + Point kicks = 15

The number of touch downs = 15 - Point kicks

Let the number of point kicks = P

Therefore;

The number of touch downs = 15 - Point kicks = 15 - P

The number of touch downs = 15 - P

Given that the total points of UT Longhorns = 70, we have;

6 × (15 - P) + 1 × P = 70

90 - 6·P + P = 70

5·P = 90 - 70 = 20

P = 4

∴ The number of point kicks = P = 4

The number of point kicks, extra points = 4

The number of touch downs = 15 - P = 15 - 4 = 11

The number of touch downs = 11

Round to the nearest tenth.

Answers

Answer:

The soil will occupy in 11664cm³ of the pot which is 3/4 or 0.75 of the squared based pyramid pot.

Step-by-step explanation:

The volume of a square based pyramid = V = a²h/3

a = base edge or side length = 36cm

h = height = 36cm

V = 36² × 36/3

V = 15552cm³

Luis wants to fill the pot with soil so that the soil takes up 75 % the pot's volume.

75% of the pot's volume =

75/100 × 15552cm³

= 11664cm³

The soil will occupy 11664cm³ of the pot which is 3/4 or 0.75 of the squared based pyramid pot.

The soil will reach about 32.7 cm up the pot.
