Answer:

  A) 448 mg

  B) 3.5 mg

Step-by-step explanation:

24 days is 24/4 = 6 half-lives. That is, the mass of 7 mg is 2^-6 times the initial mass.

A) The initial mass is 2^6×(7 mg) = 448 mg

__

B) 4 weeks is 28 days, or 7 half-lives. The remaining mass will be half the amount after 6 half-lives.

  (7 mg)/2 = 3.5 mg . . . . remaining after 4 weeks

Answer:

1 L of petrol is used to travel 9 km.

Step-by-step explanation:

You can find the answers through the ratio method

20 L : 180 km

1 L : x

( x is the number we must find )

20 x = 180

x =

x = 9 km

Answer:

6 4/5

Step-by-step explanation:

He has 1 1/5 lb. He needs 8 lb.

He needs the difference between 8 lb and 1 1/5 lb, so this is a subtraction problem. We must subtract 8 lb - 1 1/5 lb.

8 - 1 1/5 =

We cna subtract the 1 from the 8, but we need a fraction with fifths at the 8 in order to subtract 1/5 from it. We borrow 1 from 8 leaving 7, and we write the 1 as the fraction 5/5. Now we have

= 7 5/5 - 1 1/5

We subtract 1 from 7 leaving 6, and we subtract 1/5 from 5/5 leaving 4/5.

= 6 4/5

Answer: 6 4/5

Answer:

x = 25°

y = 25°

Step-by-step explanation:

✔️(x + 35)° + 30° + 90° = 180° (sum of triangle)

x + 35 + 30 + 90 = 180

Add like terms

x + 155 = 180

x + 155 - 155 = 180 - 155

x = 25°

✔️(y + 30)° + 35° + 90° = 180° (sum of triangles)

y + 155 = 180

y = 180 - 155

y = 25°

Answer:

Change the minus sign to a plus. 2. ... 24. = 8. 11. 24. Find each quotient. 1. 1. 3. 1. 6. 2. 5. 8. 1. 16. 2. 1. 3 x. 6. 1 = 6 ... Write a variable expression to represent the word phrase.

The correct expression for the given condition is,

⇒ (16 ÷ 8) + 24

An expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division is called mathematical expression.

We have to given that;

The algebraic expression is,

''add 24 to the quotient of 16 and 8.''

Now, We can write the expression as;

Quotient of 16 and 8 is,

⇒ 16 ÷ 8

And, Add 24 to the quotient of 16 and 8.

⇒ (16 ÷ 8) + 24

Thus, The correct expression for the given condition is,

⇒ (16 ÷ 8) + 24

Answer:

A

Step-by-step explanation:

Hard to explain xD

Answer:

0.5625 = 56.25% probability that at least 3 flies have to be checked for eye color to observe a white-eye fly.

Step-by-step explanation:

A sequence of independent Bernoulli trials is the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

What is the probability that at least 3 flies have to be checked for eye color to observe a white-eye fly?

This is the probability of no white-eyes during the first two flies, that is, [tex]P(X = 0)[/tex] when [tex]n = 2[/tex]

Probability of white-eyes is 1/4

This means that [tex]p = \frac{1}{4} = 0.25[/tex]

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{2,0}.(0.25)^{0}.(0.75)^{2} = 0.5625[/tex]

0.5625 = 56.25% probability that at least 3 flies have to be checked for eye color to observe a white-eye fly.

Answer:

36-0.2d

Step-by-step explanation:

d refers to the number of days

This should work for your question if not I'm very sorry

The required expression for the decreasing depth of the pond is y = 36 - 0.2x, Where y is the depth of the pond after x days.

The equation is the relationship between variables and constants represented as y = ax + b  is an example of a polynomial equation.

Here,
The water depth of a pond is initially 36 inches
The water depth of a pond decreases at a rate of 0.2 inches per day through evaporation.
Let the number of the days be x , and the depth left be y
According to the question,
Total depth in x days = 0.2x
Total remaining depth = 36 - 0.2x
or
y = 36 - 0.2x

Thus, the required expression for the decreasing depth of the pond is y = 36 - 0.2x, Where y is the depth of the pond after x days.

Step-by-step explanation:

Use the formula for the volume of a sphere and fill in the given numbers. After that, it's all arithmetic. A calculator is usually helpful.

   [tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}(3.14)(2\text{ ft})^3=\dfrac{(4)(3.14)(8)}{3}\text{ ft}^3\\\\=\boxed{33.49\text{ ft}^3}[/tex]

Answer:

A) r=∛(6v)/[tex]\pi[/tex]

Step-by-step explanation:

v=1/6[tex]\pi[/tex]r³

v÷1/6=[tex]\pi[/tex]r³

(when dividing by a fraction, invert and multiply)

6v=[tex]\pi[/tex]r³

6v÷[tex]\pi[/tex]=r³

(6v)/[tex]\pi[/tex]=r³

take the cube root of both sides

∛(6v)/[tex]\pi[/tex]=∛r³

∛(6v)/[tex]\pi[/tex]=r

Answer:

A. 2

Step-by-step explanation:

Given:

DC = 1

CE = x + 4

AB = 11

BE = x + 1

Required:

Value of x

Solution:

(DC + CE) × CE = (AB + BE) × BE

(1 + x + 4) × (x + 4) = (11 + x + 1) × (x + 1)

(x + 5) × (x + 4) = (x + 12) × (x + 1)

x² + 4x + 5x + 20 = x² + x + 12x + 12 (distributive property)

x² + 9x + 20 = x² + 13x + 12

Collect like terms

x² - x² + 9x - 13x = - 20 + 12

-4x = -8

Divide both sides by -4

x = -8/-4

x = 2
