If a shopkeeper gives you a 15% discount on shirt of having total price 50, the price you will give after the 15% discount is 42.5 dollars.

If the original price of the shirt is 50 dollars, and the shopkeeper gives a discount of 15%, then the discount amount is calculated by:

Discount = Original price x Discount rate

Discount = 50 x 0.15

Discount = 7.5 dollars

The discounted price is calculated by subtracting the discount from the original price:

Discounted price = Original price - Discount

Discounted price = 50 - 7.5

Discounted price = 42.5 dollars

The discount rate of 15% means that you will save 15% of the original price, which is 7.5 dollars in this case. The discounted price is the price after subtracting the discount amount from the original price.

Answer:

78° + B = 180°

B = 102°

Step-by-step explanation:

"Supplementary" means angle A and B added together are 180°.

We know A is 78, but we don't know B

Write an equation:

A + B = 180°

Fill in what we know.

78° + B = 180° this is the equation the question is asking for.

To solve, subtract 78 from both sides of the equation.

The population after 5 years will be approximately 8.45 billion.

The exponential equation to model the world population (in billions) after t years is P(t) = 8(1.011)^t, where P(t) is the population in billions and t is the number of years after 2022.

To write this equation, we need to use the information provided in the question. The initial population in 2022 is 8 billion, so this is our starting value. The growth rate is 1.1% per year, which can be written as 1.011 in decimal form.

We can use the formula for exponential growth, P(t) = P0(1 + r)^t, where P0 is the initial population, r is the growth rate, and t is the number of years.

Substituting the values for P0 and r into the equation, we get:

P(t) = 8(1.011)^t

This equation can be used to find the population after t years.

For example, to find the population after 5 years, we can substitute t = 5 into the equation and get:

P(5) = 8(1.011)^5 ≈ 8.45 billion

Therefore, the population after 5 years will be approximately 8.45 billion.

Answer: The given expression is:

m² +........+ 1/m²

We can notice that the expression has an even number of terms, and the first and last term are perfect squares, which suggests that it might be possible to write the expression as the square of a binomial.

Let's try to write the expression in the form of (a + b)²:

(a + b)² = a² + 2ab + b²

If we set a = m and b = 1/m, we get:

(a + b)² = m² + 2(m)(1/m) + (1/m)² = m² + 2 + 1/m²

Comparing this with the given expression, we see that it is the same as the given expression with 2 added to it.

Therefore, to make the given expression a perfect square, we need to add 2 to it.

So, the term to be inserted is 2.

The expression m² +........+ 1/m² can be written as (m + 1/m)² - 2.

Step-by-step explanation:

The equation of the line is y = -4x - 15.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The line y = m(1)x + c is perpendicular to y = x/4 - 2.

This means,

y = (1/4)x - 2 is in the form of y = m(2)x + c

So,

m(1) x m(2) = -1

m(1) = -1 / (1/4)

m(1) = -4

Now,

The line intersects (4, -1).

So,

y = -4x + c

-1 = -4(4) + c

-1 = -16 + c

Down payment = $198, total monthly payment = $2088, installment price = $2286, finance charge = $1782

Down payment is the amount of money that a purchaser needs to pay at the early stage of purchasing an expensive goods.

Given, purchasing price = $1980, 18 monthly payments of $116 each.

down payment = 10%

amount of down payment = $1980 × 10/100

                                          = $198

Total amount of monthly payment = $116 × 18 = $2088

Total paid for the snow thrower on the installment plan = Down payment + all monthly payment = $198 + $2088

Total installment price = $2286

total finance charge = Stated purchased price - down payment

An equation is an expression that shows the relationship between two or more numbers and variables.

Consider that x represent the number of pounds of soap that she makes and eventually sells.

we are given that Gwen intially spent $96 to purchase soap-making equipment, and the materials for each pound of soap cost $9. This means that the total cost of making x pounds of soap would be;

thus her revenue for x pounds of soap would be

25 × x = 25x

If she eventually sells enough soap to cover the cost of the equipment, then we get;

9x + 96 = 25x

25x - 9x = 96

x = 96/16

x = 6
