Ok what’s the problem

The mass of the radioactive sample at the beginning of the 8th day of the experiment a_13=310.7.

In a lab experiment, the decay of a radioactive isotope is being observed.

At the beginning of the first day of the experiment, the mass of the substance was 1300 grams and the mass decreased by 6% per day.

[tex]a_n=a_1r^{n-1}[/tex]

Use the given value in the formula so we get,

[tex]a_{13}=1100(0.9)^{13-1}[/tex]

Simplify the given term

[tex]a_{13}=310.7[/tex]

Therefore, The mass of the radioactive sample at the beginning of the 8th day of the experiment a_13=310.7.

I m not sure but I think this is the answer

The volume of the tissue box is 180 cubic inches.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, the area of the base is 45 square inches.

The height of the box is 4 inches.

Now, volume = 45×4

= 180 cubic inches

Therefore, the volume of the tissue box is 180 cubic inches.

BDC=95

Answer:

[tex] m\angle BDC = 95\degree [/tex]

Step-by-step explanation:

[tex] In\: \triangle ACD\: \&\:\triangle BDC[/tex]

[tex] m\angle A = m\angle B[/tex] (given)

[tex]\because m\angle A = 50\degree [/tex]

[tex]\therefore m\angle B = 50\degree [/tex]

[tex] m\angle ADC = m\angle BCD[/tex] (given)

[tex]\because m\angle ADC = 35\degree [/tex]

[tex]\therefore m\angle BCD= 35\degree [/tex]

[tex] In\: \triangle BDC[/tex]

[tex] m\angle BDC = 180\degree - (m\angle B+m\angle BCD) [/tex]

(By angle sum postulate of a triangle)

[tex] m\angle BDC = 180\degree - (50\degree +35\degree ) [/tex]

[tex] m\angle BDC = 180\degree - (50\degree +35\degree ) [/tex]

Answer:

$1,649.80

Step-by-step explanation:

Sydney will have earned $1293.35 in interest by her 60th birthday.

To solve this problem, we need to use the formula for continuously compounded interest:

A = P [tex]e^{rt}[/tex]

Where:

A is the final amount of money in the account (including principal and interest)

P is the initial principal (in this case, $400)

r is the interest rate (in this case, 3.7% per year)

t is the number of years the money is invested (in this case, 39 years)

e is the mathematical constant approximately equal to 2.718

Plugging in the values from the problem, we get:

A = $400[tex]e^{0.037 \times 39}[/tex]

Calculating this, we find that A = $400[tex]e^{1.443}[/tex] = $1693.35

Therefore, he will have earned $1693.35 - $400 = $1293.35 in interest by her 60th birthday.

Step-by-step explanation:

Hello.

The Distributive Property states that

a(b+c)=ab+ac

Where

a, b, and c can be either constants or variables

we distribute a by multiplying it times b and c, and simplify if necessary.

In this case, we should distribute 12:

12(a-5)

12 times a and 12 times (-5):

12a-60

And we're done!

Answer:

13 inches

Step-by-step explanation:

In any circle, the radius is always half of the diameter.

So, the diameter can be found by multiplying the radius by 2, and the radius can be found by dividing the diameter by 2.

Since the diameter is 26 inches, we can divide this by 2 to get the radius

26/2

= 13

The radius is 13 inches

Answer:

[tex] \bf \huge13[/tex]

Step-by-step explanation:

we know that,

finding the radius

⟼ diameter = 26 inches

⟼ radius = diameter / 2

⟼ radius = 26 / 2 inches

⟼ radius = 13 / 1 inches

⟼ radius = 13 inches.

∴ radius is 13 inches .

Step-by-step explanation:

The age multiplied 55, so the shell grows at rate of 55mm per year

in fact if the age is 2 we have (55 x 2) = 55 + 55

if 3 = (55 x 3) = 55 + 55 + 55

and so on

When the turtle is hatched the shell is 37 mm in lenght.

In fact, if we substitute 0 to a, we have

s = (55 x 0) + 37

s = 37

when the turtle is 1 year old, the shell is 92 mm in length.

in fact if we substitu a with 1, we have

s = (55 x 1) + 37

s = 55 + 37

s = 92
