Answer:

The area is 72.

Step-by-step explanation:

2 * 6 = 12

6 * 10 = 60

60 + 12 = 72

Hope this helped! Have a nice day! Plz mark as brainliest!!!

Answer:

(8,1)

Step-by-step explanation:

When flipping across the y axis, the y coordinate stays the same, while the x coordinate changes it's sign.

(x,y) - > (-x,y)

(-x,y) -> (x,y)

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:

[tex] \frac{15625}{4096} [/tex]

monomial

Step-by-step explanation:

k2 is a monomial because having only one element is monomial

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:

- $36,120

- $35,945

Step-by-step explanation:

This problem is rather pretty simple when breaking it down. We really just need to ask ourselves what the percent is of our whole and then add that to our total. Work shown below.

Step 1:

Move decimal over on both. You should get...

.032 and .027

(You always move it two to the left in these types of cases.)

Step 2:

Multiply our original price by inflation decimal. You should get...

$35,000 x .032 = $1,120

$35,000 x .027 = $945

Step 3:

Add our previous answer to our original price. You should get...

$35,000 + $1,120 = $36,120

$35,000 + $945 = $35,945

- This is our final answer, as the pricing increased due to inflation.

Note: Inflation means their is an increase in price.

Answer:

BD = 6

Step-by-step explanation:

Theorem:  The altitude to the hypotenuse of a right triangle is the mean proportional between the segments of the hypotenuse.

So, [tex]\frac{4}{BD} = \frac{BD}{9}[/tex]

[tex]BD^{2} = 36[/tex]

BD = 6

See how easy that is IF you know the theorem.

9514 1404 393

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:

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:

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.
