Answer:

$0.91

Step-by-step explanation:

Given:

If one pound of Parmesan cheese costs $14.60, to find the cost of a one-ounce portion, simply divide the cost of one pound by 16:

[tex]\implies \textsf{1 ounce portion}=\dfrac{\$14.60}{16}=\$0.9125=\$0.91\;\sf (nearest \; cent)[/tex]

Therefore, the standard portion cost for a one-ounce portion of Parmesan cheese is $0.91 (nearest cent).

The inequality is |4x-2|+1>7. By solving inequality we got x>-1 and x>2.

Given that,

The inequality is |4x-2|+1>7

We have to solve the inequality.

|4x-2|+1>7

Take +1 and right hand side we get -1

|4x-2|>7-1

Subtracting 7-1

|4x-2|>6

Now, it is modulus so we get + or -

1st we take +

4x-2>6

Take -2 and right hand side we get +2

4x>6+2

Adding 6+2

4x>8

Taking 4 to right hand side we get in the division.

x>8/4

x>2

Now, take -

-(4x-2)>6

Multiplying -1 on both sides

4x-2>-6

Take -2 and right hand side we get +2

4x>-6+2

Subtracting -6 and 2

4x>-4

Taking 4 to right hand side we get in the division.

x>-4/4

x>-1

Therefore, by solving inequality we got x>-1 and x>2.

In the PEMDAS method of solving , it goes to the five basic operations

1.Parenthesis 2. Exponents 3. Multiplication 4. Addition 5.Substraction

In this exercise there are NOT parenthesis, so then the first operation is Exponentiation and 2nd operation is Multiplication

So the answer is Multiply, the first option.

========================================================

Explanation:

Imagine a rectangle that is 12 by 26. Multiplying the length and width will get us the area.

We can break the 12 into 10+2

Also, break the 26 into 20+6

Check out the diagram below. We have 4 smaller rectangles. Finding the product of those sub-areas will then get us the partial products needed.

In the bottom right corner we have a 2 by 6 rectangle, so it has area 2*6 = 12 square units. This is one of the four partial products. The other partial products are found the same way.

Once you determine the four partial products, we then add them up

12+60+40+200 = 12+100+200 = 12+300 = 312

Therefore, 12*26 = 312 which we can use a calculator to confirm.

The value of the expression will be equal to 55.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that 6 is added to the product of 7 and a number 7. The expression will be written as,

E = 7 x 7 + 6

E = 49 + 6

E = 55

Therefore, the value of the expression will be equal to 55.

The percentage of increase in her score is 6.82%

Here we will define her first score, 88, as the 100%.

So we can write the relation:

88 = 100%.

Her next score is 94, this will be a percentage X, then we can write:

94 = X

Taking the quotient between the two equations:

94/88 = X/100%

Solving this for X we get:

(94/88)*100% = X = 106.82%

The difference between the percentages gives the increase:

106.82% - 100% = 6.82%

If to find the height of a very tall pine tree, you place a mirror on the ground and stand where you can see the top of the pine tree. The height of  the tree is 72 feet.

Given data;

6 ft

2 ft 24 ft

Hence,

Angle of incidence = Angle of reflection

Hence,

m ∠ ACD = m ∠ ECD

Two triangle will only be the same if their corresponding angles are congruent
So,

Sine m ∠ ACD = m ∠ ECD

m Δ ABC  = Δ EDC

The corresponding of similar triangles are proportional

Hence,

BC / DC = AB / ED

= 2 / 24 = 6 / ED

2ED = 24 × 6

2ED = 144

Divide both side by 2

ED = 144 / 2

ED = 72 feet

Therefore we can conclude that the tree height is measure at 72 feet.

We get 700,000 after rounding off to the place value of the underlined digit in the number 698,072.

According to the question,

We have the following number with 6 as the underlined digit:

698,072

When rounding off the number, please note that the digits to the right of the underlined digit would be zero. However, we need to be careful where we need to scale up the underlined number or it would remain the same.

For this, we need to check the number to the right of the underlined digit. If the number right next to the underlined digit is greater than 5 then the underlined digit has to be scaled up. And if it is less than 5 then the underlined digit remains the same.

So, after rounding off we will get:

700,000

Hence, the number after rounding off to 6 in 698,072 is 700,000.

The number line 5 ≤ 8-3x  shows the solution to the inequality as x cannot be more than 1.

A inequality compares two values and indicates whether one is smaller, larger, or simply not equal to the other.

a  ≠ b is the information that a and b are not equal.

If a  > b, a is greater than b. (these two are defined as strict inequality)

a ≤ b proves that a is less than or equal to b

a ≥ b proves that a is greater than or equal to b

The number line 5 ≤ 8-3x  shows the solution to the inequality as x cannot be more than 1.

If x is more than 1, lets say 2

Then the inequality as follows

The highest common factor of the given number is 35.

The biggest positive number that divides each integer in a set of two or more is known as the greatest common divisor in mathematics. The GCD of two integers x, and y is the greatest common divisor of x and y. A group of numbers' largest factor that they all share is known as the group's greatest common factor (GCF). Components 2 and 4 are shared by the numbers 12, 20, and 24, for instance. We claim the GCF of 12, 20, and 24 equals 4 since 4 is the largest. The greatest integer that may divide two or more numbers is known as the highest common factor (HCF), sometimes known as the GCF. The definition of highest is the highest or largest number. Any two or more numbers that share a common meaning.

The scooter travels 60 feet in 4 seconds, so it is going faster than the skateboard, which travels 55 feet in 4 seconds. A cargo ship traveled 150 nautical miles in 6 hours at a constant speed. How far did the cargo ship travel in one hour?

We need to find which expression represents the situation given, in this case we have two values a distance (80 ft) and the elapsed time (40 s). The time is the input of the equation, it will be placed on the "x" variable and the distance is the output of the equation, it will be placed on the "y" variable. We need to find the expression that outputs "80" when we input 40. Let's check them one by one:

A.

This outputs 20 ft when we input 40 s, therefore it is not this one.

B.

This one outputs 160 ft when we input 40 s, therefore it is not this one.

C.

This one outputs 80 ft when we input 40 s, therefore this is the correct expression.

We now need to use this expression to calculate the distance the person will travel in 10 seconds, so we will make x equal to 10 s.

The person will walk 20 ft.

The correct option is "C".

The value of x is 10.

A mathematical expression consists of a statement, at least one arithmetic operation, and at least two integers or variables. With this mathematical operation, you can multiply, divide, add, or subtract.

Given:

E is between D and F.

DE = 3x + 2

EF = 18

DF = 5x

We need to determine the value of x which is a variable, whose value is unknown to us and can take any value.

So, DF = DE + EF

Substituting the given values, we get

5x = 3x + 2 + 18

5x - 3x = 20

2x = 20

x = 20/2

x = 10

Therefore, the value of x is 10.

What is  Percentage?

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, while the percent symbol, "%," is most frequently employed. A % has no dimensions and no associated unit of measurement.

Given,

No. of students using Tablet = 164

No. of students using book = 18%

The students in sixth grade either use book or tablet

When 164 student use tablet then remaining use tablet, that is 18%

Then, the remaining percent would be the students using tablet:

100% - 18% = 82%

converting 82% into decimal we get,

82 /100

i.e, 0.82

Number of students in sixth grade = 164/0.82

                                                          = 200 students

Hence, 200 students are in sixth grade
