One angle of a right triangle measures 45°. What is the measure of the other acute angle?
Answer:
Below
Step-by-step explanation:
EVERY triangle's angles add up to 180 degrees
a RIGHT triangle has a 90 degree angle
this right triangle also has a 45 degree angle
let x° = third angle
90° + 45° + x° = 180°
x = 180 - 90 - 45 = 45 degrees
What is an equation of the line that passes through the points ( 2 , 8 ) (2,8) and ( − 8 , − 7 ) (−8,−7)?
Therefore , the solution of the given problem of linear equation comes out to be y= (3/2)x + 5 .
Define linear equation.The equation y=mx+b is the basis of a linear regression model. B is the slope, and m is the y-intercept. The aforementioned sentence is repeatedly alluded to as a "math problem with two variables," despite the fact that y and y are distinct parts. In bivariate linear equations, there are only two variables. The application regions for linear equations have no definitive solutions.
Here,
We must first determine the slope of the line before using the point-slope form of the equation of a line to determine the equation of the line that goes through two points.
The angle of the line that connects the coordinates (2, 8) and (8, 7) is:
=> slope = (−7 − 8) / (−8 − 2)
=> slope = −15 / −10
=> slope = 3/2
When we express the equation of a line in the point-slope format, where (x1, y1) is one of the line's points and m is its slope, we get the following result:
=> y − y1 = m(x − x1)
By selecting the line's origin (2, 8) and substituting the slope m = 3/2, we obtain:
=> y − 8 = (3/2)(x − 2)
The equation y = mx + b is transformed into the slope-intercept form by condensing and reordering the variables.
=> y = (3/2)x + 5
Consequently, y = (3/2)x + 5 represents the equation of the line going through the points (2, 8) and (8, 7) respectively.

9-65 Eric set up this ratio for two similar triangles:
x/12 = 5/9
He solved the problem and found x = 6.67. What was his mistake? What does x REALLY equal?
Eric made the wrong ratio of the sides of the triangle. As corresponding sides of both triangles are in proportion to each other. So, the proportion will be x/12=9/5. x equal to 21.6.
Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. If the corresponding sides and angles of two triangles are proportionate, then the triangles are similar. As a result, using another triangle, we may determine the dimensions of one triangle.
So, the right ratio of the sides of the triangle is x/12=9/5
12 * 9 / 5 =x
108/5 = x
21.6 = x
Therefore, x is equal to 21.6

On a standardized science test, the seniors at a high school have a mean score of 425 with a standard deviation of 80. What is the probability that a random sample of 50 seniors has a mean score of at most 415?
The probability that a random sample of 50 seniors has a mean score of at most 415 is given as follows:
0.1894 = 18.94%.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The parameters are given as follows:
[tex]\mu = 425, \sigma = 80, n = 50, s = \frac{80}{\sqrt{50}} = 11.31[/tex]
The probability that they scored at most 415 is the p-value of Z when X = 415, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
Z = (415 - 425)/11.31
Z = -0.88
Z = -0.88 has a p-value of 0.1894.

Solve for x given the info.
Ignore the pencil mark
Answer x is 7
Step-by-step explanation:
The three angles are 104degrees, (9x-25) and unknown
The pictures shows that the two sides are equal therefore the two opposite angles are equal
104 + (9x-25) +(9x-25) =180
RE write
104 +2(9x-25) =180
Subract 104 from both sides
2(9x-25) = 180-104
2(9x-25) = 76
Divide both sides by 2
9x - 25 = 38
Add 25 to both sides
9x = 63
Divide both sides by 9
X =7
The angle is 9x-25 = 38

Given the linear function f(x) = −4x + 8, what is the value of x if f(x) = 24?
x = 104
x = −4
x = −8
x = −88
Answer:
The value of x = -4
Step-by-step explanation:
The given linear function is f(x) = -4x+8
We have to find the x corresponding to f(x) = 24
For our convenience, let f(x) = y
Then y = -4x + 8
This equation implies y in terms of x.
Isolating x to one side of the equation, we get,
x = (y - 8)/-4 = (8-y)/4
This equation gives x in terms of y.
So when f(x) = y = 24,
x = (8-24)/4
⇒ x = -4

What is work and time in mathematics?
In mathematics, work refers to the amount of effort or energy needed to complete a task or achieve a goal. Work is often measured in units such as joules or calories.
Time refers to the duration or amount of time it takes to complete a task or achieve a goal. Time is often measured in units such as seconds, minutes, hours, or days.
To estimate the time it will take Andrea and her friend to paint the fence together, we can use the formula:
Total Time = (Time for Person 1 x Time for Person 2) / (Time for Person 1 + Time for Person 2)
Using this formula, we can estimate the time it will take Andrea and her friend to paint the fence together as:
Total Time = (6 hours x 4 hours) / (6 hours + 4 hours) = 24/10 = 2.4 hours
Therefore, the best estimate of the time it will take Andrea and her friend to paint the fence together is 2.4 hours.

The amount of room a spherical occupies inside is its volume. Because every point on the sphere's surface is equally spaced from its center, the sphere can be considered a three-dimensional round solid object. The fixed point and fixed distance, respectively, represent the sphere's center and radius. V = 4/3 r3, where r is the radius and V is the volume, is the formula for a sphere's volume. The radius of a sphere is equal to half its diameter. A circle and a sphere are both round, if you compare them. As the sphere is a three-dimensional object rather than a two-dimensional circle, we can estimate its volume and surface area.

What does 30 represent in this context?
So, 30 reflects the amount of water that is being removed from the swimming pool per minute in gallons.
How variables figure out an equation?In the provided formula, 25,000 - 30x, x is the amount of time in minutes and 30 is the pace in gallons per minute at which the pool is draining.
The expression is a linear equation of the form y = mx + b, where x is the length of time that has passed and y is the amount of water that is still in the pool.
The slope (m) of the equation in this instance is -30, which means that the pool's water level is dropping at a rate of 30 gallons per minute.
The expression's value decreases as more time passes because the value of x rises. As a result of the water draining out of the pool at a constant rate of 30 gallons per minute, the pool's volume is dropping linearly over time.

Sadie is planning to go paddleboarding this weekend, but wants to know the water temperature at the lake so she can wear the correct gear. The lake temperature is reported to be 10.5 °C today. After a few sunny days, it should be 1.5 °C warmer this weekend.
what will the water temperature be this weekend in F°?
Answer:
To convert from Celsius to Fahrenheit, we can use the formula F = (C × 1.8) + 32.
First, we need to convert 10.5 °C to Fahrenheit:
F = (10.5 × 1.8) + 32
F = 18.9 + 32
F = 50.9 °F
Then, we can add the 1.5 °C increase in temperature:
New C temperature = 10.5 + 1.5 = 12 °C
And convert that to Fahrenheit using the same formula:
F = (12 × 1.8) + 32
F = 21.6 + 32
F = 54.6 °F
Therefore, the water temperature this weekend in F° will be approximately 54.6 °F.
Jevonte mowed 6 lawns in 4 hours. What was his rate of mowing in lawns per hour?
Jevonte's rate of mowing is 1.5 lawns per hour.
How do rates work?A rate in mathematics is an indicator of how one quantity has changed in relation to another, usually given as a ratio or fraction. Rates are frequently used to explain the relationship between two quantities as they vary through time, space, or another variable. For instance, whereas interest rates track the evolution of money over time, speed tracks the change in distance per unit of time. Rates are used to describe and study numerous phenomena in several disciplines, including physics, economics, and finance.
Given that, Jevonte mowed 6 lawns in 4 hours.
Thus,
Rate of mowing = Number of lawns / Number of hours
Rate of mowing = 6 lawns / 4 hours
Rate of mowing = 1.5 lawns per hour
Hence, Jevonte's rate of mowing is 1.5 lawns per hour.
