Write a verbal expression for (c-2)d

Answer:

V = ≈615.75

Step-by-step explanation:

hopefully that helped

Answer: D

Step-by-step explanation:

3/4 is equal to 0.75.

A is pretty easy. You just add the numerator and get 3/4. So, that is NOT the answer.

B is 9/12. If you divide 9 and 12, it gives 0.75, which is equal to 0.75. This NOT the answer.

C is 6/8 and simplifies into 3/4 so is this is NOT the answer.

D is 3/12 and when you dividere the umerator and the denominator, it gives 0.25 or 1/4, which isn’t equal to 3/4. This IS the answer.

Hope this helped!

The expression that is not equal to 3/4 will be 1/12 + 2/12. Then the correct option is D.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Let's check all the options. Then we have

A. 1/4 + 1/4 + 1/4, then the value of the expression is given as,

1/4 + 1/4 + 1/4 = 3/4

B. 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8, then the value of the expression is given as,

1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 6 / 8

1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 3 / 4

C. 3 / 12 + 6 / 12, then the value of the expression is given as,

3 / 12 + 6 / 12 = 9 / 12

3 / 12 + 6 / 12 = 3 / 4

D. 1 / 12 + 2 / 12, then the value of the expression is given as,

1/12 + 2/12 = 3 / 12

1/12 + 2/12 = 1 / 4

The expression that is not equal to 3/4 will be 1/12 + 2/12. Then the correct option is D.

Answer:

Step-by-step explanation:

We use the profit concept, and doing this, it is found that if 150 televisions are sold, the profit is $50,700.

-------------------------------------------

Profit is given by revenue subtracted by cost.

In this question:

Thus, the profit of selling x televisions is:

[tex]P(x) = R(x) - C(x)[/tex]

[tex]P(x) = 3x^2 + 180x - (3x^2 - 160x + 300)[/tex]

[tex]P(x) = 3x^2 + 180x - 3x^2 + 160x - 300[/tex]

[tex]P(x) = 340x - 300[/tex]

-------------------------------------------

For 150 televisions, we have P(150), so:

[tex]P(150) = 340(150) - 300 = 50700[/tex]

If 150 televisions are sold, the profit is $50,700.

Answer:

its 30 sugar maple trees and 10 red oak trees

Step-by-step explanation:

Number of red oak trees = 10

And, Number of sugar maples trees = 30

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

Given that;

A landscaping company placed an order for 40 new trees.

And, The red oak trees cost $25 a piece and the sugar maples trees cost $18. the total order was for $790.

Let number of red oak trees = x

And, Number of sugar maples trees = y

Hence, We can formulate;

⇒ x + y = 40

⇒ 25x + 18y = 790

By solving we get;

y = 30

x = 10

Thus, Number of red oak trees = 10

And, Number of sugar maples trees = 30

Answer:

8 ducks, 12 cows

Step-by-step explanation:

Let the ducks be x in number and cows be y in number

ATQ, x+y=20 and 2x+4y=64, solving we get y=12 and x=8.

If farmer McDonald raises ducks and cows. His animals have a total of 20 heads and 64 legs. Mr. McDonald has 8 ducks and 12 cows.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, Farmer McDonald raises ducks and cows. His animals have a total of 20 heads and 64 legs.

Suppose the number of head and legs be x and y respectively.

If His animals have a total of 20 heads and 64 legs,

x+y=20

2x+4y=64,

Solving the above equations we get y=12 and x=8.

Thus, if a farmer McDonald raises ducks and cows. His animals have a total of 20 heads and 64 legs. Mr. McDonald has 8 ducks and 12 cows.

The time that taken for the two trains is 1.2 hours.

The computation of the time taken for the two trains is shown below:

Given that

The westbound train travels 55 miles per hour.

And, the eastbound train travels 75 miles per hour.

So, the total speed is

= 55 miles per hour + 75 miles per hour

= 130 miles per hour

The distance is 156 miles

So, the time taken is

[tex]= \frac{distance}{speed}\\\\= \frac{156\ miles}{130\ miles\ per\ hour}\\\\[/tex]

= 1.2 hours

Therefore we can conclude that the time that taken for the two trains is 1.2 hours.

Answer:

1.2 hours

Step-by-step explanation:

Given data:

Speed of the westbound train = [tex]55 miles/hr[/tex]

Speed of the eastbound train = [tex]75 miles/hr[/tex]

Since the trains are moving in the opposite direction their relative speed becomes,

[tex]55 miles/hr +75 miles/hr=130 miles/hr[/tex].

Since, time = distance / speed

Now the time taken for the two trains to be 156 miles apart

[tex]time = \frac{156 miles}{130 miles/hr} \\=1.2 hours[/tex]

Hence, the time taken for the two trains to be 156 miles apart = [tex]1.2 hours[/tex]

Answer:

60

Step-by-step explanation:

A circle is 360 degrees

1/6 of 360

1/6 * 360 = 60

According to the typist claim, we build an hypothesis test, find the test statistic and the p-value relative to this test statistic, reaching a conclusion that:

The p-value of the test is 0.1333 > 0.05, which means that there is not enough evidence to reject the typist's claim.

-------------------------------------------------------------

In an interview for a secretary position at the dealer, a typist claims a tying speed of 45 words per minute.

At the null hypothesis, we test if the mean is of at least 45, that is:

[tex]H_0: \mu \geq 45[/tex]

At the alternative hypothesis, we test if the mean is of less than 45, that is:

[tex]H_1: \mu < 45[/tex]

-------------------------------------------------------------

The test statistic is:

We have the standard deviation for the sample, so the t-distribution is used to solve this question

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

-------------------------------------------------------------

45 is tested at the null hypothesis:

This means that [tex]\mu = 45[/tex]

On the basis of 70 trials, she demonstrated an average speed of 43 words per minute with a standard deviation of 15 words per minute.

This means that [tex]n = 70, X = 43, s = 15[/tex]

Value of the test statistic:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{43 - 45}{\frac{15}{\sqrt{70}}}[/tex]

[tex]t = -1.12[/tex]

-------------------------------------------------------------

P-value of the test and decision:

The p-value of the test is found using a left-tailed test(test if the mean is less than a value), with 70 - 1 = 69 degrees of freedom and t = -1.12.

Using a t-distribution calculator, the p-value is of 0.1333.

The p-value of the test is 0.1333 > 0.05, which means that there is not enough evidence to reject the typist's claim.

Rebecca is wrong because she had made a pair of (1/2)x and (1/2), which is wrong. Also, pairs 5a and 5b are wrong. This is because in each of the two pairs the terms do not have the same constant term with them.
