The state of Colorado is 4 centimeters long and 2 centimeters wide on a map. A cartographer wants to use a scale factor of 3.5 to enlarge the map. What is the area of the enlarged map?
98 cm2
42 cm2
28 cm2
8 cm2
Answer: 98 cm²
Step-by-step explanation:
When a cartographer enlarges a map with a scale factor, both the length and the width are multiplied by the scale factor. In this case, the scale factor is 3.5.
Original dimensions of Colorado on the map:
Length: 4 cm
Width: 2 cm
Enlarged dimensions using the scale factor of 3.5:
Length: 4 cm × 3.5 = 14 cm
Width: 2 cm × 3.5 = 7 cm
To find the area of the enlarged map, multiply the enlarged length and width:
Area = Length × Width
Area = 14 cm × 7 cm
Area = 98 cm²
The area of the enlarged map is 98 cm².

127.6÷10 to the power of 5
im not sure if that is how you type it
Answer:
338262.124
Step-by-step explanation:
127.6/10 = 12.76 (depending on how many zero is how much you'll move the decimal to the left)
12.76^5 = 338262.124 because it's 12.76x12.76x12.76x12.76x12.76
In X8, Erin had the following capital gains (losses) from the sale of her investments: $2,600 LTCG, $24,400 STCG, ($9,600) LTCL, and ($15,600) STCL. What is the amount and nature of Erin's capital gains and losses?
Erin's capital gains are the sum of her long-term capital gains (LTCG) and short-term capital gains (STCG), which is $2,600 + $24,400 = $27,000.
Erin's capital losses are the sum of her long-term capital losses (LTCL) and short-term capital losses (STCL), which is ($9,600) + ($15,600) = ($25,200).
Since Erin's capital gains exceed her capital losses, she has a net capital gain of $27,000 - $25,200 = $1,800.
The nature of Erin's capital gains and losses are as follows:
LTCG: long-term capital gain, meaning the asset was held for more than one year before it was sold.STCG: short-term capital gain, meaning the asset was held for one year or less before it was sold.LTCL: long-term capital loss, meaning the asset was held for more than one year before it was sold.STCL: short-term capital loss, meaning the asset was held for one year or less before it was sold.(Need help please and thank you!) :)

In order to find the f(x) or y value, you have to replace x with the given one in the table:
x = -1,
[tex]y = \sqrt[3]{ - 1 - 7} = \sqrt[3]{ - 8} = - 2[/tex]
.
x = 6,
[tex]y = \sqrt[3]{ 6 - 7} = \sqrt[3]{ - 1} = - 1[/tex]
.
x = 7,
[tex]y = \sqrt[3]{7 - 7} = \sqrt[3]{0} = 0 [/tex]
.
x = 8,
[tex]y = \sqrt[3]{8 - 7} = \sqrt[3]{1} = 1 [/tex]

x = 15,
[tex]y = \sqrt[3]{15 - 7} = \sqrt[3]{8} = 2[/tex]

Which expressions are equivalent to the one below? Check all that apply. 21^x/3^x
The only equivalent expression is option (a) [tex]7^x[/tex].
What is expression ?
An expression in mathematics is a group of symbols that represent a statistical correlation or quantity, such as integers, variables, and operators. It may contain exponents, logarithms, and trigonometric functions in addition to mathematical operations like addition, multiplication, multiplication, and division. It may also contain constants, variables, and functions. Expressions can be used in a variety of subjects, including mathematics, calculus, geometry, and statistics, to represent mathematical models, resolve equations, and carry out calculations.
To find equivalent expressions for[tex]21^x/3^x[/tex], we can try to simplify the expression using exponent rules.
21 can be factored as 7*3, so we can write:
[tex]21^x/3^x = (7 × 3)^x/3^x = 7^x × 3^x/3^x = 7^x[/tex]
Therefore, we can see that option (a) 7^x is equivalent to the given expression.
To check the other options:
b) [tex](7/3)^x[/tex] = [tex](7^x)/(3^x)[/tex] which is not equivalent to the given expression.
c) [tex]3^(2x+1)[/tex] can be written as [tex]3^(2x)[/tex] × [tex]3^1[/tex] = [tex](3^2)^x[/tex] × 3 = [tex]9^x[/tex] × 3 which is not equivalent to the given expression.
d) [tex]7^(x-1)[/tex] can be written as [tex]7^x/7[/tex] which is not equivalent to the given expression.
e) [tex](3/7)^x[/tex] is not equivalent to the given expression.
Therefore, the only equivalent expression is option (a) [tex]7^x[/tex].

how will the product change if one number is increase by a factor of 12 and the other is decreased by a factor of 4
Using factors, we can conclude that the new product will be 48 time more than the old product.
Define factors?In mathematics, the factor of a number is a divisor of the inputted integer that entirely divides it, leaving no residue. We can use a variety of techniques, including the division method and the multiplication method, to identify a number's components.
Let the product be P.
Let the numbers be a and b.
Now,
P = a × b
According to the question.
Let a is increased by a factor of 12 and b by 4:
P = 12a × 4b
P = 48 × a × b

ans r=31/5 of a large wall was covered in red paint, 1/10 in blue paint, and 1/4 in green paint. What
percentage of the whole wall is covered in paint (of any colour)?
19%
32%
55%
50%
68%
Answer:
55% of the whole wall is covered in paint of any color.
Step-by-step explanation:
To determine what percentage of the wall is covered in paint, we need to add the fractions of the wall covered by each color of paint and then convert the result into a percentage.
Red paint: 1/5
Blue paint: 1/10
Green paint: 1/4
First, we need to find a common denominator, which is the least common multiple (LCM) of the denominators 5, 10, and 4. The LCM of 5, 10, and 4 is 20. Now, we can convert the fractions to equivalent fractions with a denominator of 20:
Red paint: (1/5) * (4/4) = 4/20
Blue paint: (1/10) * (2/2) = 2/20
Green paint: (1/4) * (5/5) = 5/20
Now, add the fractions:
Total paint coverage = 4/20 + 2/20 + 5/20 = (4 + 2 + 5)/20 = 11/20
To convert this fraction to a percentage, we can divide 11 by 20 and multiply the result by 100:
(11/20) * 100 = 0.55 * 100 = 55%
Thus, 55% of the whole wall is covered in paint of any color.
Tom has $160,000 in his retirement account. It is earning an APR of 4.57%. What would be the monthly yield on the account for a 30-year period?
The monthly interest yield on Tom's retirement account for a 30-year period would be $637.71.
Assuming that the interest is compounded monthly, the monthly yield on Tom's retirement account with an APR of 4.57% for a 30-year period can be calculated using the formula:
Monthly Yield = (Principal × Monthly Interest Rate) ÷ (1 - (1 + Monthly Interest Rate[tex])^{(-Number of Months)}[/tex]
Here, Principal = $160,000
APR = 4.57%,
Number of Months = 30 years ÷ 12 months/year = 360 months.
First, we need to convert the APR to a monthly interest rate by dividing it by 12:
Monthly Interest Rate = 4.57% × 12
Monthly Interest Rate = 0.3808%
Monthly Yield = (160000 × 0.3808%) ÷ (1 - (1 + 0.3808%[tex])^{-360}[/tex]
Monthly Yield = $637.71

The federal government has developed the body mass index (bmi) to determine ideal weights. a person's bmi is directly proportional to his or her weight in pounds and inversely proportional to the square of his or her height in inches. (a bmi of 19 to 25 corresponds to a healthy weight.) a 6-foot-tall person weighing 177 lb has bmi 24. find the bmi (to the nearest whole number) of a person whose weight is 176 lb and whose height is 77 in.
The BMI of a person whose weight is 176 lb and whose height is 77 inches is 21.
First, let's use the given information to find the constant of proportionality in the BMI formula:
BMI = k × (weight in pounds) / (height in inches)²
When the 6-foot-tall person weighing 177 lb has a BMI of 24, we can plug in the values and solve for k:
24 = k ₓ 177 / (72²)
k = 24 ₓ (72²) / 177
k ≈ 9.94
Now we can use this value of k to find the BMI of the person whose weight is 176 lb and whose height is 77 in:
BMI ≈ 21
BMI = 9.94 ₓ 176 / (77²)
Therefore, the BMI (to the nearest whole number) of the person is 21, which falls within the healthy weight range of 19 to 25.
