Tristan should make 8 pieces of length 0.125 yards each to make a steps to the deck 1 yards above.

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

0.125

We get the length of each step to be 0.125 yards.

Therefore, Tristan should make 8 pieces of length 0.125 yards each to make steps to the deck 1 yards above.

Answer:

The cost of lamp and everything else will be equal to $85.25 and $49.75 respectively.

This question can be solved by converting it into the form of linear equation. A linear equation can be expressed in the form of y = ax + b where a, b are coefficients and x, and y are independent and dependent variables. We know the total sale which is equal to $135. Let us assume the cost of everything else as x. Now, the cost of lamps is $35.50 more than cost of everything else that is equal to x + 35.50. Now, the linear equation will be written as

135 = x + (x + 35.50)

135 = 2x + 35.50

=> 2x = 99.5

=> x = $49.75 which is the cost of everything else and cost of lamp = x + 35.50 = $85.25.

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

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Because it is treated as regular income, the amount that was withdrawn is subject to taxation at the same rate as ordinary income under the federal income tax system.

The price of 12 inch bun purchased by Elinor is $5.32.

For the given question;

Elinor wanted to have a bun.

The cost of 18 inch hoagie bun is $7.99.

As there is only 12 inch bun present, the price of 12 inch bun is calculated by unitary method.

The price can be written as;

18  inch -------> $7.99

For 1 inch bun, divide both side by 18.

18/18  inch -------> $7.99/18

1  inch -------> $7.99/18

For 12 inch, multiply each side by 12.

12  inch -------> $7.99×12/18

12  inch -------> $5.32

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]
