-40-2(3m+1/2) =7m-2
Answer:
Step-by-step explanation:
-Start by distributing the 2, -2(3m+1/2).
-Getting -6m-1, your equation should look like -40-6m-1=7m-2
-Combine -40 and -1 to get -41, and then add the -6m to the other side.
-The equation should look like -41=13m-2. Add the 2 to the -41 to get -39.
-Now, we have -39=13m. divide both sides by 13 to get m=-3.

Helpful conversions: 1 acre =43,560 square feet 1 hectare =10,000 square meters 1lb=454 grams 1 kg=2.2lbs=1000grams 1. Scouting for cover crop establishment in the field requires conversion of your massbased seeding rate (e.g., lbs/acre) to a population-based establishment rate (e.g., plants/f? ). Let's practice doing that. Convert the following seeding rates: a. Cereal rye - 60 ibs/acre = H seeds/square foot b. Crimson clover −15 kg/ha= H seeds/square meter 2. Convert the following population-based seeding rates to mass-based seeding rates. a. Oats −30 plants/square foot = Ibs seedlacre b. Hairy vetch −20 plants/square meter = kg seedsha 3. Your farm manager wants you to drill crimson clover seed, but the seed hasn't arrived yet and you don't know if it's coated or not. If the seed is not coated, the seeding rate is 20 blacre. Will you need to increase or decrease your seeding rate if the seed is coated?
Coating the seed typically improves seed quality and germination rates, so the same seeding rate can be maintained even with coated seed.
To convert mass-based seeding rates to population-based establishment rates, we need to consider the area conversion factors provided:
a. Given a seeding rate of 60 lbs/acre for cereal rye, we can convert it to seeds per square foot by using the conversion factor of 1 acre = 43,560 square feet.
b. Given a seeding rate of 15 kg/ha for crimson clover, we can convert it to seeds per square meter using the conversion factor of 1 hectare = 10,000 square meters.
To convert population-based seeding rates to mass-based seeding rates, we can use the given area conversion factors:
a. Given a seeding rate of 30 plants/square foot for oats, we can convert it to pounds of seed per acre.
b. Given a seeding rate of 20 plants/square meter for hairy vetch, we can convert it to kilograms of seed per hectare.

The slope of the line is -1.
A line's slope is defined as the ratio of the change in y coordinate to the change in x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by the symbols y and x, respectively to calculate the slope.The common form for two-variable linear equations is Ax + By = C , where the slope is -A/C.For instance, the linear equation 7x + 3y = 1 uses standard form. Finding an equation's two intercepts (x and y) is fairly straightforward with this procedure, the slope is -7/3 .The cartesian equation for a straight line is Y = mx + c, where m stands for the gradient or slope of the line and c for the point at which it intersects the y-axis.Now the given points are : (-4,6) and (-1,3)
We know that the slope of a line is given by :
\(m=\frac{y_2-y_1}{x_2-x_1}.\)
Now we can put the values of the points to get the slope as
\(m=\frac{3-6}{-1-(-4)}\\\\\)
or , m = -1

A mathematical expression is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) It is possible to contrast expressions and phrases.
An expression or algebraic expression is any mathematical statement that has variables, integers, and an arithmetic operation between them. For example, the phrase 4m + 5 has the terms 4m and 5, as well as the provided expression's variable m, all separated by the arithmetic sign +.
Because the same individual cannot win more than one medal, we must compute the number of ways to give the medals using permutations and combination without repetition. There are 30 options to pick the gold medallist from 30 people, 29 ways to choose the silver medalist from the remaining 29 people, and 28 ways to choose the bronze medalist from the remaining 28 people. As a result, the total number of options is:

suppose that the mean time for a certain car to go from 0 to 60 miles per hour was 6.7 seconds. suppose that you want to set up a statistical test to challenge the claim of 6.7 seconds. what would you use for the null hypothesis?
For the statistical test to challenge the claim of 6.7 seconds as the mean time for a car to go from 0 to 60 miles per hour, the null hypothesis would state that the true mean time is equal to 6.7 seconds.
In a statistical hypothesis test, the null hypothesis (H0) represents the assumption or claim that is being tested. In this case, the claim is that the mean time for a car to accelerate from 0 to 60 miles per hour is 6.7 seconds.
Therefore, the null hypothesis would be formulated as follows:
H0: The true mean time for the car to go from 0 to 60 miles per hour is equal to 6.7 seconds. The alternative hypothesis (Ha) would then be formulated as the opposite of the null hypothesis, indicating that there is a difference between the true mean time and 6.7 seconds:
Ha: The true mean time for the car to go from 0 to 60 miles per hour is not equal to 6.7 seconds.
By setting up this statistical test, we can gather evidence to either support or challenge the claim made about the mean time.

a girl is about to enter puberty. how long will the total process take? group of answer choices about 5 years, for every child about 2 years, for every child about 9 years, for every child a variable length of time for different girls
The total duration of the puberty process can be different for each girl who is about to enter it, as the length of time for the different stages of puberty can vary from person to person. Hence, if a girl is about to enter puberty, the total process will take a variable length of time for different girls.
The total process of puberty for a girl can take a variable length of time, but typically it takes around 2 to 5 years to complete. The onset of puberty usually occurs between the ages of 8 and 13, with most girls starting around age 11.
The process of puberty includes physical changes such as breast development, the growth of pubic and underarm hair, and the onset of menstruation.
The duration of puberty can also depend on factors such as genetics, nutrition, and overall health. Some girls may experience a shorter or longer duration of puberty than others. However, in general, the process of puberty for a girl usually takes around 2 to 5 years to complete.
Therefore, the correct answer is "a variable length of time for different girls", but typically takes around 2 to 5 years to complete.

R={c:x is factor of 12} and M ={x:x is factor of 16}
The intersection of sets R and M is {1, 2, 4} since these numbers are factors of both 12 and 16.
To find the intersection of sets R and M, we need to identify the elements that are common to both sets. Set R consists of elements that are factors of 12, while set M consists of elements that are factors of 16.
Let's first list the factors of 12: 1, 2, 3, 4, 6, and 12. Similarly, the factors of 16 are: 1, 2, 4, 8, and 16.
Now, we can compare the two sets and identify the common factors. The factors that are present in both sets R and M are: 1, 2, and 4. Therefore, the intersection of sets R and M is {1, 2, 4}.
In set-builder notation, we can represent the intersection of R and M as follows: R ∩ M = {x : x is a factor of 12 and x is a factor of 16} = {1, 2, 4}.
Thus, the intersection of sets R and M consists of the elements 1, 2, and 4, as they are factors of both 12 and 16.

Does the geometric sequence converge or diverge? Explain. 40, -10, 2.5, -0.625, .... A. The sequence converges because |r| = 0.25, which is less than 1.
B. The sequence converges because r = 0.25, which is less than 1.
C. The sequence converges because r = -4, which is less than 1.
D. The sequence converges because |r| = 4, which is less than 1.
The sequence converges because option A is correct: |r| = 0.25, which is less than 1.
In a geometric sequence, convergence or divergence is determined by the common ratio (r). If the absolute value of the common ratio |r| is less than 1, the sequence converges. Otherwise, if |r| is greater than or equal to 1, the sequence diverges.
In the given sequence 40, -10, 2.5, -0.625, ..., we can calculate the common ratio by dividing any term by its preceding term. For example, -10 divided by 40 gives us -0.25, 2.5 divided by -10 gives us -0.25, and so on. Therefore, the common ratio is -0.25.
To determine if the sequence converges or diverges, we need to check the absolute value of the common ratio |r|. In this case, |r| is equal to 0.25, which is less than 1. Hence, the sequence converges.
Therefore, option A is correct: The sequence converges because |r| = 0.25, which is less than 1.
