Answer:

  8.9

Step-by-step explanation:

We know that 81 = 9², so √80 will be slightly less than 9. We can get a pretty good estimate by averaging 9 with 80/9. That result is 8.94, so about 8.9.

The attached graph shows that point on a number line.

Answer:

f ≈ 5

Step-by-step explanation:

Step 1: Write equation

6(2f - 4) = 31

Step 2: Solve for f

Distribute 6: 12f - 24 = 31

Add 24 on both sides: 12f = 55

Divide both sides by 12: f = 55/2

Simplify: f = 4.58333

Round: f ≈ 5

Answer: £4.20

Each 2 of pencils is £4.20 multiply that by 3 your get 12.60, the notebook is the same price of 2 pencils so that must mean it is £4.20

4.20 x 4 = 16.80

3 £4.2 from the 6 pencils

and 1 £4.2 from the notebook

Hope this helps!

The required cost of a notebook would be an amount of £4.20.

The equation is defined as mathematical assertions that have a minimum of two terms containing variables or numbers that are equal.

Let's assume that n is the cost of a notebook, p is the cost of a pencil, and b is the total bill.

We know that the notebook costs the same as two pencils, so we can write this as an equation:

n = 2 × p

We also know that Petra's bill is £16.80, so we can write this as an equation:

b = n + 6 × p

Substituting the first equation into the second equation, we get:

b = n + 6 × p

b = (2 × p) + 6 × p

b = 8 × p

We can now solve for p by dividing both sides of the equation by 8:

p = b / 8

p = £16.80 / 8

p = £2.10

Since the notebook costs the same as two pencils, we can now solve for n by substituting the value of p into the first equation:

n = 2 × p

n = 2 × £2.10

n = £4.20

Therefore, the cost of a notebook is £4.20.

Answer:

D. 8/4

Step-by-step explanation:

Actually, 8/4 is basically 8 divided by 4, which is 2. And 2 is a whole number not decimal number, so that would be your answer.

The fraction number (8/4) that is equal to the whole number is 2. Then the correct option is D.

A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.

Answer:

Step-by-step explanation:

If  1 out of 7 students are liberal arts majors based on Ms. samuel survey, the  estimate of the number of students who are liberal arts majors if the total number of student in the college s 12,000 can be gotten using the equality expression.

7 students = 1 liberal art major student

12,000 = x liberal art major students

cross multiply

7*x = 12000*1

7x = 12000

divide both sides by 7

7x/7 = 12000/7

x = 1714.29

x≈ 1714

Hence the best estimate for the number of students who are liberal arts majors is 1714 students.

Answer:

$3,270

Step-by-step explanation:

A = P(1 + rt)

First, converting R percent to r a decimal

r = R/100 = 18%/100 = 0.18 per year.

Putting time into years for simplicity,

6 months / 12 months/year = 0.5 years.

Solving our equation:

A = 3000(1 + (0.18 × 0.5)) = 3270

A = $3,270.00

The total amount accrued, principal plus interest, from simple interest on a principal of $3,000.00 at a rate of 18% per year for 0.5 years (6 months) is $3,270.00.

Answer: x=6.9

Step-by-step explanation:

In the problem, it is stated that y=65.37. All we have to do is plug that into y and solve for x.

65.37= 8.3x + 8.1                [subtract both sides by 8.1]

57.27=8.3x                          [divide both sides by 8.3]

x=6.9

Answer:

12 less than or equal to 2

Step-by-step explanation:

The inequality for the given statement is $12 ≤ $2(n).

The equations with inequalities are those who have unequal sides on both sides. Unlike the equation, we compare the two values when we work with inequality. The equal sign is substituted between by being less than (or less than or equal to), larger than (or greater or equal to), or not equal to sign.

As per provided data from the question,

Total money to spent on the ride tickets = $12

Price of each ticket for a ride =$2

So, the inequality will be : $12 ≤ $2(n), here n is the number of rides.

Step-by-step explanation:

If there are 2.2 in 1 kilogram and you are trying to find out how many are in many kilograms then you multiply.

Hopefully this helps you :)

pls mark brainlest ;)

The expression that represents the pound of weight in x kilogram can be written as 2.2x, where x represents the weight in kilograms.

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

As it is given that there are 2.2 pounds in 1 Kilogram. Therefore, the expression that represents the pound of weight in x kilogram can be written as 2.2x, where x represents the weight in kilograms.

Answer:

Arrange the data in ascending order

1,1,2,3,4,4,4,5,5,5,5,6,6,7,8,11

n=16

position of median = (n+1)/2 = 17/2 = 8.5 th item

8.5 th item is the average of 8 and 9th item

median = (5+5)/2 = 5

Range = largest value - smallest value

           = 11 -1 = 10

position of Q1=  (n+1)/4 = 17/4 = 4.25 th item

Q1 = 4 + 0.25(5th item - 4th item )

    4 + 0.25(4-3)

Answer:

k = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 5 ← is in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus the 2 points have a slope of - 3

calculate the slope using the slope formula and equate to - 3

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, - 1) and (x₂, y₂ ) = (k, 5)

m = [tex]\frac{5+1}{k-4}[/tex] = [tex]\frac{6}{k-4}[/tex] = - 3 ( multiply both sides by (k - 4) )

- 3(k - 4) = 6 ( divide both sides by - 3 )

k - 4 = - 2 ( add 4 to both sides )

k = 2

Answer:

FH = 36 units

Step-by-step explanation:

Points F, G and H are collinear.

Therefore, by joining segments FG and GH we get a segment FH.

FH = FG + GH

By substituting the values of the segments given in the question,

FH = (3x - 1) + (2x + 2)

     = 5x + 1

Since, GH = 16

2x + 2 = 16

2x = 14

x = 7

Therefore, FH = (5x + 1)

                       = 35 + 1

                       = 36 units

Measure of segment FH = 36 units.
