Answer: MNO is  an isosceles triangle

Step-by-step explanation:

the right hand corner is 80 degrees and the left one is 45 degrees, you work this out by knowing a straight line is 180 degrees, 180-110 is 70. 55+70=125 and then 180-125 is 55.

Step-by-step explanation:

we just open the bracket and multiply

Answer:

a. 11.6 (rounded to nearest tenth)

b. Yes

Step-by-step explanation:

a²+b² = c²

6²+10² = c²

36²+100 = c²

136 = c²

√136 = √c²

11.6  = c

b. because 11.6 is the hypotenuse (longest side length) and there is 6 and 10 as the shorter leg lengths.

The solution of the inequality 15n>8n-21 is given by, n<-3.

Inequality is a relation between two or more mathematical expression or quantities via unequal signs i.e. greater, less, greater or equal, less or equal, not equal.

Given that the inequality is 15n<8n-21

Solving the inequality we have,

15n<8n-21

15n-8n<8n-21-8n, subtracting from both sides

7n<-21

n<-3, dividing 7 from both sides

So the solution of the given inequality is, n<-3.

Answer:

  10.3 cm

Step-by-step explanation:

You want the measure of side 'r' in triangle QRS, given s = 4.2 cm, R = 160°, and S = 8°.

The law of sines tells you side lengths are proportional to the sine of the opposite angle.

  r/sin(R) = s/sin(S)

  r = s×sin(R)/sin(S) = (4.2 cm)sin(160°)/sin(8°)

  r ≈ 10.3 cm

Answer:

125.0272

Step-by-step explanation:

7 (1.14)^22

Each hour it grows 14%. This means after 1 hour, it has grown 7*1.14. After two hours 7*1.14 (1.14) or 7*(1.14)^2, etc so after 22 hours use equation above to solve.

After 22 hours the bacteria will be 125 bacterias.

The growth rate of bacteria is given an exponential growth rate of 14%. Initially, there are 7 bacteria after 22 hours what would be the numbers of bacteria to be determined.

The function which is in format f(x) =   where, a is constant and x is variable,  the domain of this exponential function lies   (-∞, ∞).  

Function for the growth rate of the bacteria is given by
= 7(1+14%)^x
=  7(1.14)^x

For 22 years,
= 7 (1.14)^22
= 125

Thus, After 22 hours the bacteria will be 125 bacterias.

Answer:

$20.45

Step-by-step explanation:

Since the Bayside Bugle charges $18 for the first 20 words and there is more than 20 words in the ad you take 27-20 and you get 7 additional words.

Now we know that we already have to pay $18 for the first $20 words.

Since we have 7 additional words we multiply that by 0.35 cents and you get $2.45.

Next we add up our two numbers (2.45+18) we get the total of $20.45 fro a 27-word ad.

I hope this helps :)

The cost of 27 word ad is $20.45

An equation is a mathematical expression that contains an equals symbol.

Given that, The Bayside Bugle charges by the word to run automotive ads. The newspaper charges $18 for the first 20 words and $0.35 for each additional word

Let the total be cost C and number of additional words be n, the equation =

C = 18 + 0.35n

For 27 additional words, the cost will be,

C = 18 + 0.35*7

C = 18 + 2.45

C = 20.45

Hence, The cost of 27 word ad is $20.45

Answer:7/25 × 5/24

Step-by-step explanation:

7 oatmeal 25 all together

Then 5 peanut butter 24 left since he ate one

The probability of randomly selecting an oatmeal cookie first is approximately 7/25, and the probability of selecting a peanut butter cookie second is approximately 5/24.

Use the concept of probability defined as:

Probability is defined as the ratio of the total number of favorable outcomes to the total number of outcomes.

Given that,

Ethan buys a bag of cookies.

The bag contains different types of cookies:

chocolate chip, peanut butter, sugar, and oatmeal.

The quantities of each type of cookie in the bag are:

6 chocolate chip cookies

5 peanut butter cookies

7 sugar cookies

7 oatmeal cookies

To calculate the probability,

To determine the total number of cookies in the bag and the number of oatmeal cookies and peanut butter cookies.

In this case,

Ethan has a total of,

6 + 5 + 7 + 7 = 25

So there is 25 cookies in the bag.

Since there are 7 oatmeal cookies in the bag.

So, the probability of randomly selecting an oatmeal cookie first = 7/25,

After eating the oatmeal cookie,

There are now 24 cookies left in the bag, with 5 peanut butter cookies remaining.

Therefore,

The probability of randomly selecting a peanut butter cookie second is 5/24

Answer: 20

Step-by-step explanation:

If the least value of n is 4, then the inequality best shows all the possible values of n is, n ≥ 4. So Option B is correct

Inequalities are the comparison of mathematical expressions, whether one quantity is greater or smaller in comparison to another quantity.

We use these symbols to represent inequalities, '>' , '<', '≥', '≤'

Given that,

The least value of n is 4,

Inequality representation = ?

It is known that,

Least value  of n is 4

So, Minimum possible value of n is 4

Maximum value of n should be more than 4,

In order to satisfy the condition,

So,

n  > 4

By combining both the things,

It can be written as,

n ≥ 4

Hence, the best inequality representation is n ≥ 4

Answer:

x ≈ 11.09

Step-by-step explanation:

Using the rule of logarithms

\(log_{b}\) x = n ⇒ x = \(b^{n}\)

Given

ln(x + 9) = 3 , that is

\(log_{e}\) (x + 9) = 3 , then

x + 9 = e³ ( subtract 9 from both sides )

x = e³ - 9 ≈ 11.09 ( to the nearest hundredth )

The triangle given is a scalene acute triangle

A triangle can be classified based on the measures of its angles and the lengths of its sides.

In this case, the angle measures of the triangle are 82, 75, and 23 degrees. Since the sum of the angles in a triangle is always 180 degrees, we can verify that these angles satisfy this condition: 82 + 75 + 23 = 180.

The triangle is not an equilateral triangle because all the sides are not of equal length.

The triangle also doesn't have one right angle so it can't be right triangle.

Now, as per the angle measures, none of the angles are right angles, but one angle is greater than 90 degree, so this triangle is not acute triangle.

So, this triangle is not an Obtuse triangle since it has no angle greater than 90 degrees.

As the triangle has no sides of equal length, it is also a Scalene triangle.

Therefore, the triangle would be classified as a Scalene acute triangle (c).

The sampling distribution  of the sample proportion is approximately normal when the sample size (n) is large and the population proportion (p) is close to 0.5.

This can be mathematically expressed as follows:

\(n*p > 10 and n*(1-p) > 10\)

To illustrate, let's say we are sampling from a population with a proportion of 0.3. For the sampling distribution to be approximately normal, the sample size (n) must be larger than 33.3 (n > 33.3). This is because \(33.3*0.3 = 10 and 33.3*0.7 = 23.3\).

In other words, the sample size (n) must be large enough so that the product of the sample size (n) and the population proportion (p) is greater than 10 and the product of the sample size (n) and the population proportion (1-p) is also greater than 10. This ensures that the sampling distribution of the sample proportion is approximately normal.

To sum up, the sampling distribution of the sample proportion is approximately normal when the sample size (n) is large and the population proportion (p) is close to 0.5.
