By applying the criterion of the law of cosine, the triangle presented in the picture is possible.
Is this triangle possible?
Herein we find an hypothetical triangles with all side lengths known. A criterion is using the law of cosine, a possible triangle has cosine values between - 1 and 1. Then, we proceed to check for each side:
cos A = - (a² - b² - c²) / (2 · b · c)
cos A = - (25² - 2² - 24²) / (2 · 2 · 24)
cos A = - 0.469
cos B = - (b² - a² - c²) / (2 · a · c)
cos B = - (2² - 25² - 24²) / (2 · 25 · 24)
cos B = 0.998
cos C = - (c² - a² - b²) / (2 · a · b)
cos C = - (24² - 25² - 2²) / (2 · 25 · 2)
cos C = 0.53
Since the law of cosine gives realistic results, then the triangle presented in the picture is possible.

Answer:
x°=113°
y°=67°
z°=49°
Step-by-step explanation:
Looking at the right triangle exclusively, we know that it must have 180° in total.
Set up an equation that represents this:
28°+39°+x°=180°
Simplify:
67°+x°=180°
Solve:
x°=113°
Now, we also know that x°+y°=180°, because they form a line. Now that we know the value of x°, plug it in to this equation:
113°+y°=180
Solve:
y°=67°
Finally, apply the same logic with the first triangle with the other triangle:
64°+67°+z°=180°
Simplify:
131°+z°=180°
Solve:
z°=49°
Fill in the missing number. % of 98 = 49
50%
since 98/2 = 49

How many squares would have to be shaded so that 2/9 of the shape is shaded?
Answer:
4.
Step-by-step explanation:
There are 18 squares, if you want to shade 2/9 you have to make the denominator, which is 9 into 18, so you multiply by 2, you will do the same thing to the numerator, 2x2=4 9x2=18.
Brainiest would be appreciated.
There are 4 squares that would have to be shaded so that 2/9 of the shape is shaded.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
We have to determine the number of squares that would have to be shaded so that 2/9 of the shape is shaded
According to the given figure,
There are 3 rows and 6 columns of squares
So the number of squares would be 3 × 6 = 18
There are 18 squares, therefore if you want to shade 2/9, you must first divide the denominator, which is 9 into 18, by 2, and then multiply by 2.
If 2/9 of the shape is shaded: 18 × 2/9 ⇒ 36/9 = 4
Hence, there are 4 squares that would have to be shaded so that 2/9 of the shape is shaded.

what are 3 combinations of coins with the value of 30% of a dollar
The 3 combinations of coins with the value of 30% of a dollar are 2 dimes + 1 Nickel + 5 Pennies, 1 dime + 2 Nickels + 10 Pennies, 3 Nickels + 1 dime + 5 Pennies.
How many types of coins are there?
There are 4 types of coins. They are Quarter, Nickel, dime, and Penny.
1 Quarter = 25 cent
1 dime = 10 cents
1 Nickel = 5 cents
1 penny = 1 cent
Now calculate 30 percentage of a dollar.
1 dollar = 100 cents.
30% of 100 cents = (30/100) × 100 = 30 cents.
2 dimes + 1 Nickel + 5 Pennies = 20 cents + 5 cents + 5 cents = 30 cents
1 dime + 2 Nickels + 10 Pennies = 10 cents + 10 cents + 10 cents = 30 cents
3 Nickels + 1 dime + 5 Pennies = 15 cents + 10 cents + 5 cents = 30 cents

Find the least common denominator or LCM of the two denominators:
LCM of 2 and 8 is 8
Next, find the equivalent fraction of both fractional numbers with denominator 8
For the 1st fraction, since 2 × 4 = 8,
12 = 1 × 42 × 4 = 48
Likewise, for the 2nd fraction, since 8 × 1 = 8,
18 = 1 × 18 × 1 = 18
Subtract the two like fractions:

26. Parallel lines m and n intersect parallel lines x and
y, representing two sets of intersecting railroad
tracks. At what angles do the tracks intersect?
By applying the respective theorems for parallel lines, the angles at which the tracks intersect is 55 degrees (55°).
What are parallel lines?Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.
In Mathematics, there are four (4) special angle relationships that are typically formed when two or more parallel lines are intersected by a transversal and these include the following:
Corresponding angles.Alternate interior angles.Same-side interior angles.Alternate exterior angles.By applying the respective theorems for parallel lines, including the same-side interior angles (supplementary angle) theorem, we have:
x + 125° = 180°
x = 180° - 125°

Compared to a z-score, a hypothesis test with a t statistic requires more information from the sample.
a) True
b) False
The statement is b) False. A hypothesis test with a t statistic does not require more information from the sample; it utilizes different information and assumptions compared to a z-score depending on the characteristics of the data.
A hypothesis test with a t statistic does not require more information from the sample compared to a z-score. In fact, the t statistic is used when the sample size is small or when the population standard deviation is unknown, whereas the z-score is used when the sample size is large and the population standard deviation is known.
In hypothesis testing, both z-tests and t-tests are used to make inferences about a population based on sample data. The main difference between them lies in the assumptions made about the population standard deviation.
In a z-test, the population standard deviation is known and used in the calculation of the test statistic, which follows a standard normal distribution. Therefore, it requires knowledge of the population standard deviation.
On the other hand, in a t-test, the population standard deviation is unknown and estimated using the sample standard deviation. The test statistic in a t-test follows a t-distribution, which takes into account the variability introduced by the estimation of the population standard deviation. Hence, it requires less information about the population compared to a z-test.
The t statistic takes into account the sample size and the sample standard deviation to estimate the population parameters, while the z-score uses the known population parameters. Therefore, the t statistic provides a more accurate inference when the sample size is small or when the population standard deviation is unknown.
In conclusion, a hypothesis test with a t statistic does not require more information from the sample; it utilizes different information and assumptions compared to a z-score depending on the characteristics of the data.

hi i am stuck on this word problem and need help
Solution
Given that the Perimeter is: 340 yards. Lenght is 91 yards
Since P = 2(L + W)
where L is the Length
W is the width
=> 340 = 2(91 + W)
=> 340 = 182 + 2W
=> 158 = 2W
Dividing both sides by 2
=> W = 79
Hence, the width is 79 yards
Answer: it would be 79yards
Step-by-step explanation: 91•2=182
340-182=158
158/2=79yards

Answer:
C) 6
Step-by-step explanation:
I converted the equation into slope-intercept form and then identified the y-intercept.
\(4x+2y=12\\\\4x-4x+2y=12-4x\\\\2y=12-4x\\\\\frac{2y=12-4x}{2}\\\\ y=6-2x\\\\y=-2x+6\\\\y=-2x+\boxed{6}\)
C should be the correct answer.
Hope this helps.
Answer: 6
Step-by-step explanation: The y-intercept is a point where a line
crosses the y-axis and all y-intercepts have an x-coordinate of zero.
So to find the y-intercept of this line, we can plug a 0 in for x.
So we have 4(0) + 2y = 12.
So 2y = 12 which means that y = 6.
So the y-intercept of this line is 6.

b. Would a negative profit make sense in this problem? Explain.
In order to determine if a negative profit would make sense in this problem, we need to understand the concept of profit. Profit is the financial gain obtained from a business transaction after deducting the expenses.
It is calculated by subtracting the total expenses from the total revenue.
If the profit is negative, it means that the expenses exceed the revenue, resulting in a loss. In some cases, a negative profit can make sense. For example, during the initial stages of a business, it is common to have negative profits as the expenses may be higher than the revenue. This is a temporary situation as the business strives to establish itself and increase its revenue.
In the context of your question, it is not clear what problem or scenario you are referring to, so I cannot provide a specific answer. However, generally speaking, a negative profit may not make sense in the long run as businesses aim to generate positive profits to sustain their operations and achieve growth.
Whether a negative profit makes sense or not depends on the specific circumstances of the business and the stage it is in. It is important to analyze the revenue and expenses to determine the financial health and viability of the business.
