If an item has a sale price of $40 after it has been discounted 30%, what was the original price

Answer:

b=46

Step-by-step explanation:

First we know that the sum of all three angles is 180. So that gives us the equation 2b+88=180, then we can solve.

2b=180-88

2b=92

b=46

So that means b=46!

As you may know, a straight line = 180°

Since we already have 88° as one of the values, we can simply subtract that from 180.

180 - 88 = 92

Next, divide 92 by 2

92 ÷ 2 = 46

With that being said, we can conclude that the value of B is 46.

You can double check this by adding all of the values together: 46 + 46 + 88 = 180

Algebra is a branch of mathematics that deals with symbols and the rules for manipulating these symbols to solve equations and understand mathematical relationships. It involves the use of letters and symbols to represent variables and numbers, and the manipulation of these variables and numbers using rules and operations such as addition, subtraction, multiplication, and division. The main goal of algebra is to solve equations, which involves finding the value of an unknown variable that satisfies the given equation.

In algebra, equations are often represented graphically as lines or curves on a coordinate plane, which allows for a visual representation of mathematical relationships. Algebraic equations are used in a variety of fields, including physics, engineering, finance, and computer science.

The study of algebra starts with basic arithmetic concepts and progresses to more complex topics such as linear equations, quadratic equations, and functions. The ability to understand and manipulate algebraic expressions is an essential skill in many areas of life, from solving practical problems to understanding complex mathematical theories.

If each of the 16 Cougar Scouts gets 1/4 of a cup of birdseed, then the total amount of birdseed in the bag can be found by multiplying the amount given to each scout by the number of scouts:

Total birdseed = (1/4) x 16 = 4 cups

Therefore, there are 4 cups of birdseed in the bag.

The dilation of the black figure to blue figure is a reduction with a scale factor of 0.5

A dilation is defined as a transformation that produces an image that is the same shape as the original, but is a different size.

It can either be an enlargement or a reduction.

An enlargement means a scale factor greater than 1 while a reduction is a scale factor less than 1.

Thus, this dilation is a reduction.

Coordinates of initial figure are:

(-8, 10), (10, 10), (8, -8), (2, -8)

Coordinates of dilated figure are:

(1, -4), (4, -4), (-4, 5), (5, 5)

Thus, it is clear that the scale factor is 0.5

.....Answer:

..........Step-by-step explanation:

Therefore, we can expect the world population to be around 17.6 billion in the year 2100 if it continues to increase exponentially with a doubling time of 60 years.

A decimal place is a position in a number that is to the right of the decimal point. It represents a fractional part of the number. For example, in the number 3.14159, the digit "1" is in the tenths place, the digit "4" is in the hundredths place, the digit "1" is in the thousandths place, and so on. Each place value to the right of the decimal point represents a power of 10 that is negative, such as tenths, hundredths, thousandths, ten-thousandths, and so on. The number of decimal places determines the degree of precision in the number.

by the question.

To determine the population in the year 2100, we need to calculate how many times the population will double between 2022 and 2100, which is 78 years.

78 years divided by 60 years is approximately 1.3, which means that the population will double 1.3 times between 2022 and 2100.

2 to the power of 1.3 is approximately 2.2, which means that the population in 2100 will be 2.2 times the population in 2022.

So, the population in 2100 will be:

8 billion x 2.2 = 17.6 billion (rounded to one decimal place)

24, 36, 48.

Step-by-step explanation:

Represent the three even numbers as 2x, 2y, 2z, where x,y,z are integers.

2x+2y+2z = 108

x+y+z = 54

Let x≤y≤z

x = z/2

y = ¾z

z/2 + 3z/4 + z = 54

2z/4 + 3z/4 + 4z/4 = 54

2z + 3z + 4z = 216

9z = 216

z = 24

x = z/2 = 12

y  = ¾z = 18

Therefore, The numbers are 24, 36, 48.

Answer:

[tex]P= \frac{A}{(1+\frac{r}{n})^{nt} }[/tex]

A = $600,000.00

n = 1  (annually)

t = 25 years

First, convert R as a percent to r as a decimal

r = R/100

r = 8/100

r = 0.08 per year,

Then, solve the equation for P

[tex]P= \frac{A}{(1+\frac{r}{n})^{nt} }[/tex]

[tex]P= \frac{6000000}{(1+\frac{0.8}{1})^{1*25} }[/tex]

69) If 10 packages of shallots cost $40, then the cost of one package of shallots can be calculated as:

$40 ÷ 10 packages = $4 per package

To find out how many packages of shallots can be purchased with $8, divide the total amount of money by the cost per package:

$8 ÷ $4 per package = 2 packages

Therefore, with $8, you can buy 2 packages of shallots.

70) If three Bosc pears cost $2, we can use a proportion to determine how many pears we can buy for $4:

3 pears / $2 = x pears / $4

Cross-multiplying, we get:

3 pears × $4 = $2 × x pears

Simplifying, we get:

12 = 2x

Dividing both sides by 2, we get:

x = 6

Therefore, with $4, you can buy 6 Bosc pears.

71)If the exchange rate is 11 pounds for every $2, we can use a proportion to determine how many pounds we can get if we exchange $4:

11 pounds / $2 = x pounds / $4

Cross-multiplying, we get:

11 pounds × $4 = $2 × x pounds

Simplifying, we get:

44 = 2x

Dividing both sides by 2, we get:

x = 22

Therefore, if you exchange $4, you can get 22 pounds.

72) If 9 packages of basil cost $27, we can use a proportion to determine how many packages of basil we can buy for $9:

9 packages / $27 = x packages / $9

Cross-multiplying, we get:

9 packages × $9 = $27 × x packages

Simplifying, we get:

81 = 27x

Dividing both sides by 27, we get:

x = 3

Therefore, with $9, you can buy 3 packages of basil.

Picking a male youngster who enjoys playing video games is more likely if you get a score of (4/10) * (6/10) = 24/100 = 6/25.

Probability is a mathematical concept that expresses the possibility or chance of an event happening. It is stated as a number between 0 and 1, where 0 denotes the impossibility of an event and 1 denotes its certainty. By dividing the number of favorable outcomes by the entire number of possible possibilities, the probability of an event is determined.

given

The odds of selecting a male adolescent at random are x/n, while the odds of selecting a teen whose preferred pastime is playing video games are y/n.

As these two occurrences are separate, the likelihood that both will occur is the product of the probabilities:

The odds of selecting a male teen who enjoys video games are (x/n) * (y/n) = xy/n2.

By dividing the numerator and denominator by the greatest common factor (GCF) of x and y, if one exists, this can be made simpler.

For instance, the probability is simplified as follows if x=4 and y=6, where the GCF is 2:
