Step-by-step explanation:

Please mark brainliest and 5 stars!

Answer:

The formula would be:

27500 x (1 - 14/100)^year = 4000

=> (86/100)^year = 4000/27500

=> 0.86^year = 0.145

=> year = log(0.145)/log(0.86) = 12.8

Hope this helps!

:)

Answer:

13 years

Step-by-step explanation:

4000 = 27500 × (1 - 14/100)^t

4000 = 27500 × 0.86^t

0.86^t = 8/55

t ln(0.86) = ln(8/55)

t = 12.78248711

Answer:

1/258 *(t^28)

= t^28 / 4^4

= t^28 4^-4

= (t^-7 * 4)^-4

= (4t^-7)^-4

The simplified form of an expression   [tex]\frac{1}{256} * t^{28}[/tex] will be [tex](4 t^{-7})^{-4}[/tex] which is given in option number [tex](D)[/tex] i.e. ([tex]4\ t[/tex] Superscript negative [tex]7[/tex] Baseline) Superscript negative [tex]4[/tex] .

Simplified form a rational expression is considered simplified if the numerator and denominator have no factors in common.

We have,

 [tex]\frac{1}{256} * t^{28}[/tex]

Now to simplify it,

Convert [tex]256[/tex] into a exponent form with a base.

i.e.

[tex]\frac{1}{4^4} * t^{28}[/tex]

Now,

Using the exponent rule;

[tex]\frac{1}{a^n}= a^{(-n)}[/tex]

So,

[tex]4^{-4}\ *\ t^{28}[/tex]

Now, simplify it more by taking common power of [tex]4[/tex] and [tex]t[/tex] ,

[tex](4\ *\ t^{-7})^{-4}[/tex]

⇒ [tex](4 t^{-7})^{-4}[/tex]

So, this is the simplified form of given expression which is given in option number [tex](D).[/tex]

Hence, we can say that the simplified form of an expression   [tex]\frac{1}{256} * t^{28}[/tex] will be [tex](4 t^{-7})^{-4}[/tex] which is given in option number [tex](D)[/tex] i.e. ([tex]4\ t[/tex] Superscript negative [tex]7[/tex] Baseline) Superscript negative [tex]4[/tex] .

Total cost = $13.96

Step-by-step explanation:

The total to be paid for the item is the addition of its price plus the taxes. That is:

[tex]Total\,\,cost=13.42+0.04\,*\,13.42\\Total\,\,cost=13.42+0.5368\\Total\,\,cost==13.9568[/tex]

Which can be rounded to $13.96

Answer:

In the triangle ABC,  A is the right angle;  the side "a", opposite to the angle A, is the hypotenuse and side "b" is the leg.

√ (√2)²-1² = √2-1= √1= 1

according to the Pythagorean theorem.

It means that you have the right angled triangle with congruent legs; thus the triangle is isosceles.

Hence, the angles at the base (at the hypotenuse) are congruent and each is equal to  180°-90°/2 = 45°

Answer.  The measure of the angle B is 45°.

Step-by-step explanation:

The required value of the angle B is obtained as 45°.

The trigonometric ratios are defined for a right angled triangle.

The example of these ratios are sin, cos, tan, cosec, sec and cot.

The trigonometric ratios are useful in determining the heights and distances of the large objects.

The given problem can be shown in the form of diagram as below,

The measure of given sides and angle of the triangle are as below,

∠A = 90°, a = BC = √2 and b = AC = 1.

Use the trigonometric ratio to obtain,

Sin∠B = BC/AC

⇒ Sin∠B = 1/√2

⇒ ∠B = 45°

Hence, the measure of angle B is given as 45°.

Answer:

The volume of a cylinder:

[tex]V \approx 150.796[/tex] [tex]ft^3[/tex]

Step-by-step explanation:

To find the volume of a cylinder, you need the this formula:

[tex]V = \pi r^2h[/tex]

-Use the given height and radius for the formula:

[tex]V = \pi 4^2 3[/tex]

-Then, solve the formula:

[tex]V = \pi \times 4^2 \times 3[/tex]

[tex]V = \pi \times 16 \times 3[/tex]

[tex]V = \pi \times 48[/tex]

[tex]V = 48\pi \approx 150.796[/tex]

So, the volume of a cylinder is approximately [tex]150.796[/tex] [tex]ft^3[/tex] .

Answer:

1176π m³

Step-by-step explanation:

The formula for the volume of a cylinder is:

V = πr²h

Let's substitute the values given into this equation:

V = πr²h

V = (π)(14²)(6)

Solve:

V = (π)(14²)(6)

V = (π)(196)(6)

V = 1,176π

Therefore, the volume of the cylinder is 1176π cubic meters.

Answer:

1176

Step-by-step explanation:

r (radius) = 14 m

h (height) = 6 m

v (volume) = ?

Formula: V=πr2h

We are looking for the volume of the cylinder. We know that the Radius is 14 and the height is 6.

So we need to

1: Radius * 14 * 6

2: Radius * 196* 6

Answer: 1176

Answer:

Next year Aimee will be 13 years old

Step-by-step explanation:

Let's call Aimee's age A, and Jamie's age J.

From the information given, we have that:

A = (1/3) * J

A + 12 = (1/2) * (J + 12)

Using the value of A from the first equation in the second one, we have:

J/3 + 12 = J/2 + 6

J/2 - J/3 = 6

J/6 = 6

J = 36

Now we can find A:

A = (1/3) * 36 = 12

So next year Aimee will be 13 years old

Answer:

Aimee will be 13 years old next year/

Step-by-step explanation:

A stands for Aimee, and J stands for Jamie.

A = (1/3) * J

A + 12 = (1/2) * (J + 12)

Using the value of A from the first equation in the second one, we have:

J/3 + 12 = J/2 + 6

J/2 - J/3 = 6

J/6 = 6

J = 36

Now we can find A:

A = (1/3) * 36 = 12

In conclusion, Aimee will be 13 years old next year.
