Which is a correct expansion of (4x + 1)(2x7 - 2)?

Answer:

Amount of grass needed (In square meter) = 34 meter²

Step-by-step explanation:

Divide given shape into rectangle and trapezium

Given:

Width of rectangle = 2 m

Length of rectangle = 5 m

Height of parallelogram = 9 - 5 = 4 m

Base of parallelogram = 10 m

Opposite site of parallelogram = 2 m

Find:

Amount of grass needed (In square meter)

Computation:

Amount of grass needed (In square meter) = Area of rectangle + Area of parallelogram

Amount of grass needed (In square meter) = (l x b) + (1/2)(sum of parallelogram)(height)

Amount of grass needed (In square meter) = (5 x 2) + (1/2)(2 + 10)(4)

Amount of grass needed (In square meter) = 10 + (1/2)(12)(4)

Amount of grass needed (In square meter) = 10 + 24

Amount of grass needed (In square meter) = 34 meter²

The positive value of the distance between the two objects

is [tex]r = +\sqrt \frac{GM_1M_2}{F_g}[/tex].

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as its degree is two.

Given, The formula to calculate the gravitational force between two objects

is [tex]F_g = \frac{GM_1M_2}{r^2}[/tex] where r is the distance between the objects M is the individual masses and G is the gravitational constant.

Solving for r would result in two values one positive and one negative and distance can not be negative so we want the positive value.

[tex]F_g = \frac{GM_1M_2}{r^2}[/tex].

[tex]r^2 = \frac{GM_1M_2}{F_g}[/tex].

[tex]r = \pm\sqrt \frac{GM_1M_2}{F_g}[/tex].

[tex]r = +\sqrt \frac{GM_1M_2}{F_g}[/tex].

The purchasing cost of each game costs $1.55 and each song costs $1.89 according to the given equation.

A variable is a symbol or character that represents a value or set of values ​​in mathematics and computer programming that can change and take on different values ​​depending on the context.

The given problem can be solved using a system of equations.

The first formula, 5g + 8s = 22.87, represents the total cost of games and songs purchased by Cedro.

The second formula, 7s + 4g = 18.89, represents the total cost of games and songs purchased by Benita.

5g = 22.87 - 8s

g = (22.87 - 8s)/5.

We can now substitute this expression for g into the second equation and solve for s. So we have:

7s + 4((22.87 - 8s) / 5) = 18.89

On expanding and solving this equation for s we get:

7s + (91.48 - 32s) = 18.89

32s + 7s = 73.59

39s = 73.59

s = 1.89

By substituting the value of s into the equation 5g = 22.87 - 8s gives

5g = 22.87 - 8(1.89)

5g = 22.87 - 15.12

5g = 7.75

g = 1.55

The percentage increase in the price of the notebook is 15%.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100.

The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Finding the increase in the price of the notebook:

$3.80 - $3.30 = $0.50

Dividing the increase by the original amount:

0.50 / 3.30 = 0.1515

To change to a percent multiply by 100 and round off to significant numbers:

0.1515 *100 = 15.15% or, 15%.

Thus, the percentage increase in the price of the notebook is 15%.

Answer:

$6386.1140

Step-by-step explanation:

Using the compound interest formula :

A = P(1 + r/n) ^nt

P 5500 ; rate, r = 10% = 0.10 ; t = 18 months = 18/12 = 1.5 years,

Compounding times per period = 12 (monthly)

A = 5500(1 + 0.1/12)^12*1.5

A = 5500(1 + 0.0083333)^18

A = 5500(1.0083333)^18

A = 5500 * 1.1611116

A = 6386.1140

Hence, amount to be repaid = $6386.1140

Answer:

x = 16±2√94 over 3

Step-by-step explanation:

Move terms to the left side.

0 = -6x² + 64x + 80

- ( -6x²+64+80) = 0

Distribute

- ( - 6x²+64x+80) = 0

6x² - 64x - 80 = 0

Common factor

6x² - 64x - 80 = 0

2 (3x²-32x--40) = 0

Divide both sides by the same factor

2 (3x²-32x--40) = 0

3x² - 32x - 40 = 0

When 392,196 is divided by 87, the answer obtained using long division is 4,508.

The mathematical procedure for splitting big numbers into several smaller groups or sections is known as long division. The dividend is the number we divide into smaller groups, while the divisor is the number through which we divide. Difficulty difficulty can be solved by breaking it down into manageable parts.

Dividend : 392,196

Divisor: 87 (number that divides)

39 / 87 = 0

392 / 87 = 4 (87x 4 = 348) - 4 is the first digit of the result

392 - 348 = 44 (remainder)

441 (next digit is one) / 87 = 5 (87x 5= 435) - 5 is the second digit

441-435 = 6 (remainder)

69 / 87 = not possible so add a 0, which is the third digit

696 / 87 = 8 (87x 8 = 696)

696- 696 = 0 (not remainder)

When 392,196 is divided by 87, the answer obtained using long division is 4,508.

The cost of a carpet of the same quality, measuring 5m by 3m is $129.

We can use the unitary method to solve this problem. The unitary method is a technique used for solving a problem by first finding the value of a single unit, and finding the necessary value by multiplying the single unit value.

In this question, it is given that a carpet measuring 4m × 2.5m costs $86. That means the 10m² area of carpet costs $86 if we divide 10 by both the cost and area of the carpet we will find that, 1 m² area of carpet will cost $8.6. So the cost of a carpet of 5m × 3m will be the area of the carpet multiplied by the cost of the carpet per 1 m² i.e, 15m² of carpet will cost $8.6 × 15 which is equal to $129.
