Step-by-step explanation:

x/7=12

Solution

For this case we have the following:

g = 12 and h=19

And we want to find 3h(h-g)

If we replace we got:

3*19 (19-12) =57*7=399

Then the answer would be:

Answer:

[tex]\frac{2}{3}[/tex] and [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

(a)

fraction Rhys gets is [tex]\frac{16}{24}[/tex] = [tex]\frac{2}{3}[/tex]

(b)

Ben is left with £24 - £16 = £8

then fraction Ben has left is

[tex]\frac{8}{24}[/tex] = [tex]\frac{1}{3}[/tex]

We solve as follows:

So, the value of "blank" is 80.

Using proportions, it is found that the maximum the company can expect for returned items is of:

$4,616.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations such as multiplication or division along with the unit rates in the context of this problem.

The lost amount to returns each day is of 15% of 27235, and this amount is calculated as follows:

0.15 x 27235 = $4,085.25

(the decimal equivalent of the percentage is multiplied by the original amount to find the equivalent amount).

The margin of error is of 13%, hence this amount can still be increased by 113, that is, multiplied by 1.13, hence:

4085.25 x 1.13 =  $4,616.

The whole twenty thousand dollars that were distributed has to be accounted for as part of the gross revenue.

This is further explained below.

Generally, A person's or a household's gross income is the whole amount of money earned before any deductions or taxes are taken out of that income. This includes all wages, salaries, profits, interest payments, rentals, and other types of earnings.

Because it is treated as regular income, the amount that was withdrawn is subject to taxation at the same rate as ordinary income under the federal income tax system.

If, on the other hand, Kathy makes the decision to convert her 401(k) to a Roth 401(k), then any money she takes out of the account will not be subject to taxes.

Answer:

A = 7986 m²

Step-by-step explanation:

the field is in the form of a trapezium.

the area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular distance between the bases b₁ and b₂

here h = 66 , b₁ = 102, b₂ = 140 , then

A = [tex]\frac{1}{2}[/tex] × 66 × (102 + 140) = 33 × 242 = 7986 m²

Answer:

7986 m²

Step-by-step explanation:

The field geometric shape is a trapezoid whose bases are 102 m and 140 m and height of 66m

The equation for the area of a trapezoid is given by
[tex]A = \dfrac{a + b}{2} h\\\\[/tex]

where a and b are the two sides and h is the height

Here a = 102, b = 140 and h = 66

Substitute these values directly into the equation for area

[tex]A = \dfrac{102 + 140}{2} \times 66\\\\A = (102 + 140) \times \dfrac{66}{2}\\\\\\102 + 140 = 242\\\\\dfrac{66}{2} = 33\\\\\\A = 242\ \times 33 = 7986\; m^2[/tex]

Where

Thus, if we substitute the above values into the equation:

Pencils: $0.25 each

Notebooks: $2.50 each

Backpacks: $32 each

The cost of the notebooks (C) must be equal to the price of each notebook (2.50) multiplied by the number of notebooks bought (x)

In contrast to velocity, which describes the speed and direction of an object's movement, speed is the rate of movement along a path. Alternatively, velocity is a vector while speed is a scalar quantity. Velocity and speed are denoted by the letters v and v, respectively (boldface). The symbol has a bar over it for average values. How swiftly something is going, being done, or something that is moving quickly is measured in terms of speed. Driving an automobile 45 miles per hour is an illustration of speed.

Division is breaking a number up into an equal number of parts. Mathematically, we can write "[a] divided by [b]" as a ÷ b. The division algorithm is given by -

D = dq + r

[D] - Dividend

[d] - Divisor

[q] - Quotient

[r] - remainder

Given is Tristan who is building steps up to a deck that is 1 yards above the ground. The steps must all be the same height an he wants to make 8 steps.

Total number of steps to be made = [n] = 8

Height of deck = [h] = 1 yard.

Now, we have to divide 1 yard into 8 equal parts. Therefore, assume

that -

A = 1 ÷ 8

A = 1/8

Part A.

From the given table, we can see that the variable occupation is a Categorical variable becasue the occupation can divide a set of people into groups. Then, the level of measurement is Nominal because the occupation describes the objects by labels, with no quantitative value.

Part B.

Temperature is a Quantitave variable because we can measure the temperature of an object. Regarding the level of measurement, the temperature is an Interval variable because zero temperature is not the lowest possible temperature.

Part C.

The price is a Quantitative variable because the price is a numerical value with a meaningful order. Regarding the level of measurement, the price is a Ratio variable because it has a true zero, meaning that we can take ratios of values.

The prediction of outcomes of the number of 1 is 12

The given parameters are

Device = A die

Number of rolls = 72

From the question, the die is six-sided

This means that the sample space is

S = {1, 2, 3, 4, 5, 6}

So, the probability of rolling a 1 is

P(1) = 1/6

When the die is rolled 72 times, the number of outcomes of 1 is

Outcomes = P(1) * n

Where n = 72

So, we have

Outcomes = 1/6 * 72

Evaluate

Outcomes = 12

Hence, the prediction is 12

In the small triangle

There are a right angle and an acute angle of measure 53 degrees

Since the sum of the angles of a triangle is 180 degrees

Then 90 + 53 + < 1 = 180 degrees

Then 143 + < 1 = 180

Subtract 143 from both sides

Then < 1 = 37 degrees

Since <2 is an exterior angle of the small triangle

Then its measure = the sum of <1 and 90 degrees

Then < 2 = 37 + 90 = 127 degrees

In the triangle of angles 2, n3 and 30

< 2 + < 3 + 30 = 180

127 + < 3 + 30 = 180

Add 127 and 30

157 + <3 = 180

<3 = 23

The answer is < 2 = 127 degrees and < 3 = 23 degrees
