Answer:

  2x +3y = -27

Step-by-step explanation:

You want an equation for a line parallel to 2x +3y = 5 and through the point (-3, -7).

A parallel line will have the same slope as the given line, but will have different intercepts. In the standard-form equation given, that means the coefficients of the variables will be the same, but the constant will be different.

To make the constant appropriate for the given point, we use the (x, y) values of the given point to find it:

  2x +3y = c

  2(-3) +3(-7) = c = -6 -21 = -27

The desired equation is ...

  2x +3y = -27

Answer:

99°

Explanation:

given:

m∠2 = 55°

solve:

m∠1 +  m∠2 = ∠KJL

m∠1 = ∠KJL - m∠2

m∠1 = 154° - 55°

m∠1 = 99°

Answer:

m∠1 = 99°

Step-by-step explanation:

   m∠1 + m∠2 = m∠KJL

⇒ m∠1 + 55 = 154

⇒ m∠1 = 154 - 55

⇒ m∠1 = 99°

To calculate the interest for 1/2 a month over a period of 8 years, we first need to calculate the total number of months in 8 years:

Total number of months = 8 years x 12 months/year = 96 months

Next, we can calculate the interest for half a month:

Interest = Principal x Rate x Time

Where:

- Principal = $90,900.00

- Rate = 8.25% (annual interest rate)

- Time = 0.5/12 years (half a month, expressed in years)

Rate needs to be converted to a monthly rate, so we divide it by 12:

Rate = 8.25% / 12 = 0.6875% (monthly interest rate)

Time needs to be expressed in years, so we divide it by 12:

Time = 0.5/12 years

Now we can calculate the interest:

Interest = $90,900.00 x 0.006875 x 0.0416667

Interest = $25.08 (rounded to the nearest cent)

Therefore, the interest for 1/2 a month on a principal of $90,900.00 with an annual interest rate of 8.25% over a period of 8 years is $25.08.

Answer:

The interest for 1/2 month is $312.47, and the total interest for 8 years is $30, 032.64

The second object is approximately 4.4 * 10^9 times bigger than the first object.

The division of the value of the second scientific notation from the first scientific notation is the precise and accurate way with which we can determine many many times bigger is the second object compared to the first object.

To do so, group coefficients together and exponents together to divide numbers in scientific notation. i.e.

= (3.7/8.5) * ((10^6)/(10^−4))

= 0.43529411 ×  ((10^6)/(10^−4))

Subtract the exponent from the denominator from the exponent of the numerator for the same base 0.43529411 ⋅ 10^(6 −4*−1)

= 0.43529411 × ((10^6+4)

= 0.43529411 × 10^10

= 4.3529411 × 10^9

≅ 4.4 × 10^9

Answer: x - 2y = -10.

Step-by-step explanation:

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.

The linear function with a slope of 3 and y-intercept of 10 is y = 3x + 10.

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,

Slope = 3

y-intercept = 10

The equation of a line is given as y = mx + c

m = slope

c = y-intercept

Now,

m = 3

c = 10

So,

The linear function with a slope of 3 and y-intercept of 10 is y = 3x + 10.

Thus,

The linear function with a slope of 3 and y-intercept of 10 is y = 3x + 10.

Two objects are comparable in Euclidean geometry if they have the same form or if one has the same shape as the mirror image of the other.

The triangles are comparable if two pairs of matching angles in a pair of triangles are congruent. We know this because if two angle pairs are equal, then the third pair must be equal as well.

The probability that the ball being drawn is white is 0.2202.

To find the probability of drawing a white ball from urn A after transferring two balls from urn B to urn A, we need to consider the different possible scenarios for the transferred balls and calculate the probability for each scenario.

Scenario 1: Two green balls are transferred from urn B to urn A.
In this case, urn A will have 7 green balls and 6 white balls, for a total of 13 balls. The probability of drawing a white ball from urn A in this scenario is 6/13.

Scenario 2: One green ball and one white ball are transferred from urn B to urn A.
In this case, urn A will have 6 green balls and 7 white balls, for a total of 13 balls. The probability of drawing a white ball from urn A in this scenario is 7/13.

Scenario 3: Two white balls are transferred from urn B to urn A.
In this case, urn A will have 5 green balls and 8 white balls, for a total of 13 balls. The probability of drawing a white ball from urn A in this scenario is 8/13.

To find the overall probability of drawing a white ball from urn A, we need to find the probability of each scenario occurring and multiply it by the probability of drawing a white ball in that scenario.

The probability of scenario 1 occurring is (8/12)(7/11) = 56/132.
The probability of scenario 2 occurring is 2(8/12)(4/11) = 64/132.
The probability of scenario 3 occurring is (4/12)(3/11) = 12/132.

The overall probability of drawing a white ball from urn A is:
(56/132)(6/13) + (64/132)(7/13) + (12/132)(8/13) = 378/1716 = 0.2202.

Therefore, the probability of drawing a white ball from urn A after transferring two balls from urn B to urn A is 0.2202.

Answer:

s=P-b/2

Step-by-step explanation:

P-b=2s

P-b/2=s

The solution for the variable s in the equation P = b + 2s is s = (P - b) / 2.

To solve the equation P = b + 2s for the variable s, we need to isolate s on one side of the equation.

Here's the step-by-step process:

P = b + 2s

Subtract b from both sides:

P - b = b - b + 2s

P - b = 2s

Divide both sides by 2:

(P - b) / 2 = (2s) / 2

(P - b) / 2 = s

Therefore, the solution for s is (P - b) / 2.

Based on the data, the estimated number of lemon candies in the bag of 100 assorted candies is about 19.

In mathematics, proportion refers to the relationship between two quantities that are equivalent or have a constant ratio. It is usually expressed as a fraction or a ratio. For example, if a recipe calls for 2 cups of flour and 1 cup of water, the proportion of flour to water is 2:1 or 2/1. Proportions are used in a variety of mathematical and real-world situations, such as solving problems involving ratios, rates, and percentages.

In the given question,

We can use a simple proportion to estimate the number of lemon candies in the bag. We know that Ridgette handed out a total of 6 lemon candies out of a total of candies. Therefore, the proportion of lemon candies in the bag is:

6/total candies = number of lemon candies/100

We can cross-multiply to solve for the number of lemon candies:

number of lemon candies = 6 x 100 / total candies

We can also use the information about the other flavors to estimate the total number of candies in the bag. The total number of candies is:

total candies = lemon + orange + grape + cherry

Using the information from the table, we can estimate the total number of candies:

total candies = 6 + 5 + 8 + 13 = 32

Therefore, the estimated number of lemon candies in the bag is:

number of lemon candies = 6 x 100 / 32 = 18.75

We can round this to the nearest whole number to estimate that there were about 19 lemon candies in the bag of 100 assorted candies.
