To solve for x and find the measure of each angle, set up the equation (3x-45) + (2x + 15) = 90, combine like terms, and solve for x. Then, substitute the value of x back into the expressions for angle M and P to find their measure.

To solve for the value of x and find the measure of each angle, we'll use the fact that complementary angles add up to 90 degrees. So, we can set up the equation: (3x-45) + (2x + 15) = 90.

Now, let's solve for x:

3x - 45 + 2x + 15 = 90

Combine like terms: 5x -30 = 90

Add 30 to both sides: 5x = 120

Divide both sides by 5: x = 24.

Substitute the value of x back into the expressions for angle M and P to find their measure:

Angle M = (3(24) - 45) = 57 degrees

Angle P = (2(24) + 15) = 63 degrees

#SPJ12

Final answer:

Angles M and P are complementary, summing to 90 degrees. By setting up the equation (3x - 45) + (2x + 15) = 90 and solving for x, we find that x = 24, angle M measures 27 degrees, and angle P measures 63 degrees.

Explanation:

To solve for the value of x when angles M and P are complementary, we need to set up an equation based on the fact that the sum of complementary angles is 90 degrees. Therefore, we can write the equation as the sum of both angles: (3x - 45) + (2x + 15) = 90. After combining like terms and solving for x, we can find the measure of each angle by substituting the value of x back into the original expressions for angle M and angle P.

Write the equation for complementary angles: (3x - 45) + (2x + 15) = 90

Simplify and combine like terms: 5x - 30 = 90

Add 30 to both sides: 5x = 120

Divide by 5: x = 24

Find the measure of angle M: M = 3x - 45 = 3(24) - 45 = 27 degrees

Find the measure of angle P: P = 2x + 15 = 2(24) + 15 = 63 degrees

Thus, the value of x is 24 degrees, angle M measures 27 degrees, and angle P measures 63 degrees.

Answer:

31.2

Step-by-step explanation:

Ratio shows us the number of times a number contains another number. The weight of the fruit box is 31.2 lbs.

A ratio shows us the number of times a number contains another number.

As it is given the ratio of the fruits oranges, apples, and pears is 2:5:6. And the weight of the oranges in the box is 4.8 lbs.

Let's assume that the weight of the oranges, apples, and pears is 2x, 5x, and 6x respectively.

Now, as the weight of the oranges is 4.8 lbs, therefore,

The weight of the oranges, 2x = 4.8 lbs

                                                 x = 2.4 lbs

Now, as we know the value of x, therefore, the weight of the fruit box is,

[tex]\begin{aligned}\text{Total weight of the fruit box} &= 2x + 5x+ 6x \\&=13x \end{aligned}[/tex]

Now, substitute the value of x, therefore, we can write it as,

                                             [tex]=13x\\\\= 13(2.4)\\\\= 31.2\rm\ lbs[/tex]

Hence, the weight of the fruit box is 31.2 lbs.

The requried length of each side of the pentagon is 3.5 inches.

The perimeter of the pentagon is the measure of its circumference i.e. the sum of its 5 sides.

Here,
A regular pentagon has five equal sides. To find the length of each side of the pentagon, we need to divide the perimeter by 5.

Length of each side = Perimeter/5

Length of each side = 17.5 inches / 5

Length of each side = 3.5 inches

Therefore, the length of each side of the pentagon is 3.5 inches.

Answer:

192

Step-by-step explanation:

The balance in a bank account after 3 years with an initial deposit of $1600 and an annual interest rate of 4% is calculated using the simple interest formula. The result is a balance of $1792 after adding the interest earned to the principal amount.

The question involves finding the balance in a bank account after 3 years with an initial deposit of $1600 and an annual interest rate of 4%. This is a mathematics problem that involves the concept of simple interest.

To calculate the balance after 3 years, we can use the formula for simple interest:

Balance = Principal + (Principal × Rate × Time)

Where:

Using this information, the calculation is as follows:

Balance = $1600 + ($1600 × 0.04 × 3)

Balance = $1600 + $192

Balance = $1792

Therefore, after 3 years, the balance in the bank account would be $1792.

To model the growth of a savings account with an exponential function, we will use the formula to calculate the amount of money, A(t), accumulated after a certain number of years, t, given an initial principal amount, P, and an annual interest rate, r.

The standard formula for exponential growth in the context of compound interest is as follows:

\[ A(t) = P (1 + r)^t \]

where:
- \( A(t) \) represents the amount of money in the savings account after \( t \) years.
- \( P \) is the principal amount initially deposited into the account.
- \( r \) is the annual interest rate (expressed as a decimal).
- \( t \) represents the time in years.

For your savings account, you start with $400 (the principal amount, \( P \)), and it gains 3% interest every year (the annual interest rate, \( r \)).

Let's assign the given values to their respective variables in the formula:

- \( P = \$400 \)
- \( r = 3\% = 0.03 \) (since 3% as a decimal is 0.03)
 
Inserting these values into the formula yields the specific exponential function for this savings account:

\[ A(t) = \$400 (1 + 0.03)^t \]

This equation represents the amount of money that will be in the savings account after any number of years, \( t \), based on the continuous application of a 3% annual interest rate.

2/6 = 1/3

Step-by-step explanation:

you have a six sided dice. 2 numbers over the entire dice numbers so that would be, 2/6 which simplifies to 1/3

Have a great day!

The probability of rolling either a 3 or a 5 on a single roll of a fair six-sided die is 1/3.

To calculate the probability of rolling either a 3 or a 5 with a single roll of a six-sided die, we need to consider that there are 6 possible outcomes (the numbers 1 through 6). Since each face has an equal chance of landing face up, each single number has a probability of 1/6. When calculating the probability of rolling a 3 or a 5, we add the probabilities of these two separate events together because they are mutually exclusive outcomes.

The probability of rolling a 3 is 1/6, and the probability of rolling a 5 is also 1/6. Thus, the probability of rolling either a 3 or a 5 is given by:

(Probability of rolling a 3) + (Probability of rolling a 5) = 1/6 + 1/6 = 2/6

After simplification, the probability in its simplest form is:

The probability of rolling a sum of 4 or less with two dice is 6 out of 36 outcomes, which simplifies to 1/6 or 0.1667 when rounded to four decimal places.

To calculate the probability that the sum of two rolled dice will be 4 or less, we can list all possible outcomes (the sample space) and then count the favorable outcomes. A single six-sided die has 6 faces, so the total number of outcomes when rolling two dice is 6 × 6 = 36. The pairs of dice that sum to 4 or less are: (1,1), (1,2), (1,3), (2,1), (2,2), and (3,1). There are 6 such pairs, so the probability of rolling a sum of 4 or less is 6/36, which simplifies to 1/6.

The probability should be rounded to four decimal places if necessary, but in this case, the fraction simplifies exactly to 1/6. Therefore, the probability is 0.1667 when rounded to four decimal places.

$1300

Step-by-step explanation:

The piecewise function is defined as f(x) = 0.05x - 300 over the income range of $15,000 to $40,000. An Aribraska resident who earns $32,000 would owe $1,600 in taxes.

The piecewise function is defined as f(x) = 0.05x - 300 over the part of the domain where the income is between $15,000 and $40,000. This is because the tax rate of 5% is being applied to the income in this range. For any income above $40,000, the tax rate is 7%, so the function would not be equal to 0.05x - 300.

To calculate the amount of taxes owed by an Aribraska resident who earns $32,000, we need to determine the income range that applies to this amount. Since $32,000 is within the range of $15,000 to $40,000, we can use the piecewise function to calculate the taxes:

f(32,000) = 0.05(32,000) - 300 = 1,600

Therefore, an Aribraska resident who earns $32,000 would owe $1,600 in taxes.

Answer:

2x + 3

Step-by-step explanation:

Given

2x² + 5x + 3

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × 3 = 6 and sum = 2 + 3 = 5

The factors are 2 and 3

Use these factors to split the x- term

2x² + 2x + 3x + 3 ( factor the first/second and third/fourth terms )

= 2x(x + 1) + 3(x + 1) ← factor out (x + 1) from each term

= (x + 1)(2x + 3) ← in factored form

Thus the other factor is (2x + 3)
