Lana bought a sports car for $75,700. If the value of her car decreases 4.3% annually.
When using the exponential DECAY formula, what would be the value of r?

Answers

Given:

The initial value of the car = $75,700

Decreasing rate = 4.3%

To find:

The value of r in the exponential DECAY formula.

Solution:

The exponential decay formula is:

[tex]y=a(1-r)^t[/tex]

Where, a is the initial value, r is the rate of decay on decimal and t is the time period.

The initial value of the car is $75,700 and its value decreases 4.3% annually. So,

[tex]a=75,700[/tex]

[tex]r=\dfrac{4.3}{100}[/tex]

[tex]r=0.043[/tex]

The required exponential decay formula is:

[tex]y=75,700(1-0.043)^t[/tex]

Therefore, the value of r in the exponential decay formula is 0.043.

The 5th graders want to raise money for their overnight camping trip by selling cornbread during the school Chili Cook-Off contest. All the pans of cornbread are square. A pan of cornbread costs $12. The customers can buy any fractional part of a pan of cornbread and pay that fraction of $12. For example, ½ of a full pan costs ½ of $12.

Answers

Answer:

1 / 12 ; $1

Step-by-step explanation:

Pan was 1/4 full and she buys 1/3 of the cornbread in the pan

The fraction of cornbread she buys is :

1/3 of 1/4

1/3 * 1/4 = 1/12

Hence, she bought 1/12 of cornbread

The amount she pays :

Cost of 1 pan = $12

Therefore, the cost of 1/12 of a pan will be :

1/12 * $12 = $1

Hence, she'll pay $1

Find the missing length of the triangle
20 cm
12 cm

Answers

The shape on the left is a square with side length of 12 cm

This means the height of the triangle is 12cm.

Knowing the height and the hypotenuse using the Pythagorean you can solve for the base.

20^2 = 12^2 + x^2

400 = 144 + x^2

Subtract 144 from both sides:

256 = x^2

Take the square root of both sides

X = sqrt(256)

X = 16

Answer:

7 days

Step-by-step explanation:

(a) Filling in the given information will result in two equations in the two unknowns. Dividing one by the other will tell you the value of b.

n=2

1.8 = A₀·b²

n=3

2.4 = A₀·b³

Dividing the second equation by the first gives ...

2.4/1.8 = (A₀·b³)/(A₀·b²) = b

4/3 = b

(b) Substituting this into the first equation, we can find A₀.

1.8 = A₀·(4/3)²

1.8(9/16) = A₀ = 1.0125

A₀ is the value of A when n=0. It is the area of the patch at the beginning of observation, before any days passed.

1.0125·(4/3)^n = 7

(4/3)^n = 7/1.0125 . . . . . . . . . . . . divide by A₀

n·log(4/3) = log(7/1.0125) . . . . . . take logarithms

n = log(7/1.0125)/log(4/3) ≈ 6.72092

It will take about 7 days for the area of the patch to exceed 7 cm.

9/2 as a fraction and what is 2/3 reciprocal

Answers

9/2 is already a fraction, and the reciprocal of 2/3 and 3/2

Answer:

9/2 = 4 1/2 , 2/3 = 3/2

Step-by-step explanation:

The reciprocal of a fraction is switching the numerator and the denominator.

2/3, switched is 3/2.

To find the mixed form of an improper fraction, you divide the numerator by the denominator.

Like this, 9/2 = 4.5

4 is the whole.

So, 4 would be the whole number.

Then there is 1 left over.

You keep the denominator.

So it would be 4 1/2.

In which 3 statements below will the number 24 correctly fill in the blank? A) 2 feet = ___ inches B) 24,000 grams = ___ kg C) 3 gallons = ___ pints D) ___ pints = 12 cups E) 240 mg = ___ grams

Answers

Answer:

A,B and C.

Step-by-step explanation:

(A) 1 feet = 12 inches

So, 2 feet = 2 × 12 inches = 24 inches

(B) 1,000 grams = 1kg

So, 24,000 grams = (24,000÷ 1,000) = 24kg

(C) 1 gallon = 8 pints

So, 3 gallons = 3 × 8 pints = 24 pints

(D) 1 pints = 2 cups

So, 12 cups = (12÷ 2) = 6 pints

(E) 1 gram = 1000 mg

So, 240 mg = (240 ÷ 1,000) = 0.24 gram

Hence, A,B and C correctly fill with 24.
