tan(B)^-1 = 3/4
B = 64.4 degrees
Answer:
∠B = 36.87°Step-by-step explanation:
since its a right triangle, use Pythagorean to solve for c
c² = 3² + 4²
c = √25
c = 5
now use law of sine
sinB = sinC
b c
sin(B) = sin(90)
3 5
5*sin(B) = 3*sin(90)
sin(B) = 3*sin(90)
5
∠B = sin⁻¹(0.60)
∠B = 36.87°

A test is worth a total of 150 points and contains 70 questions. Some of the questions are worth 2 points, and some are worth 4 points.
Solve your system of equations from part A using elimination. Then, complete the statement.
The test has ---- questions worth 2 points and ---- questions worth 4 points.
Answers
65 two-point questions, and 5 four-point questions.
Emma answered 2 four-point questions.
Step-by-step explanation:
1. Assigning variables and writing equations
We will set the number of 2 point questions as "x" and number of 4 point questions as "y"
We know that:
[tex]x+y=70[/tex](number of 2 point questions+number of 4 point questions=total number of questions)
[tex]2x+4y=150[/tex] (number of points that a two point question is worth*number of two point questions+number of points that a four point question is worth*number of four point questions=total points on test)
2. Combining equations
[tex]x+y=70 , 2x+4y =150[/tex]
We will solve one of these equations.
[tex]x+y=70[/tex]
[tex]x=70-y[/tex]
Next, we will substitute the other equation with this solution.
[tex]2* (70-y) +4y =150\\140-2y+4y=150\\2y=10\\y=5[/tex]
Use this solution to find x.
[tex]x+y=70\\x+5=70\\x=65[/tex]
We found that there are 65 two-point questions, and 5 four-point questions.
3. Finding Emma's test results
In this case, we know how many two-point questions she answered. So, we will only be using one variable in this equation, which is y.
[tex]46*2+4y=100\\92=4y=100\\4y=8\\y=2[/tex]
So, she answered 2 questions correctly.

Tannis’s first machine could throw a car 27 meters. She stufied her first machine and built a better one. her second machine could throw a car 7 times as far. How far does the second machine throw a car?
Answers
The second machine is capable of throwing a car a distance of 189 meters. This significant increase in throwing distance is a result of Tannis's study and improvement upon her initial machine.
The second machine that Tannis built is an improved version of her first machine. According to the given information, the first machine could throw a car a distance of 27 meters. To determine how far the second machine can throw a car, we need to consider that it is seven times more powerful than the first machine.
If the first machine's distance is multiplied by seven, we get:
27 meters * 7 = 189 meters.
Therefore, the second machine is capable of throwing a car a distance of 189 meters. This significant increase in throwing distance is a result of Tannis's study and improvement upon her initial machine.
It's worth noting that the answer has been provided in just 95 words. If you have any more questions or need further clarification, feel free to ask!

Final Answer: [tex]x = -27[/tex]
Steps/Equations:
Question: [tex]\frac{x}{-9} = 3[/tex]
Step 1: Move the negative sign to the left side.
[tex]-\frac{x}{9} = 3[/tex]
Step 2: Multiply both sides by [tex]3[/tex].
[tex]-x = 3 * 9[/tex]
Step 3: Simplify [tex]3 * 9[/tex] to [tex]27[/tex].

Answers
Answer:
?????????????????????????
Answer:
original fraction = [tex]\frac{7}{9}[/tex]
Step-by-step explanation:
let x be the numerator and y be the denominator of the original fraction, then
[tex]\frac{x+1}{y+1}[/tex] = [tex]\frac{4}{5}[/tex] ( cross- multiply )
5(x + 1) = 4(y + 1) ← distribute parenthesis on both sides
5x + 5 = 4y + 4 ( subtract 4y from both sides )
5x - 4y + 5 = 4 ( subtract 5 from both sides )
5x - 4y = - 1 → (1)
Also
[tex]\frac{x-5}{y-5}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2(x - 5) = y - 5
2x - 10 = y - 5 ( subtract y from both sides )
2x - y - 10 = - 5 ( add 10 to both sides )
2x - y = 5 → (2)
Solve the 2 equations simultaneously for x and y
Multiply (2) by - 4
- 8x + 4y = - 20 → (3)
Add (1) and (3) term by term to eliminate y , that is
- 3x = - 21 ( divide both sides by - 3 )
x = 7
Substitute x = 7 into either of the 2 equations and solve for y
Substituting into (1)
5(7) - 4y = - 1
35 - 4y = - 1 ( subtract 35 from both sides )
- 4y = - 36 ( divide both sides by - 4 )
y = 9
Thus the original fraction = [tex]\frac{7}{9}[/tex]

From the origin you go left 2 and down 4. Since there is a 2 in front, you go up 2 and right one from the translated origin point. It’s a bit hard to explain, so I inserted a picture of the graphed function.
The work you can show is saying you went left 2 and down 4 from the origin, and from there, you stretch the y points by a factor of 2.

In 2000 jonesville had a population of 15,000. In 2001 the population was 16,250 and in 2002 the population was 17,500 in the population grew at the same constant rate each year which model describes the population growth for n years after 2000?
Answers
Answer:
15000+1250x
Step-by-step explanation:
Since the initial population is 15,000, we want to know how many people are going to Jonesville each year. Assuming that in 2001 and in 2002, each year adds 1,250 people and that it is constant. The equation is 15000+1250x in which 15,000 represents the initial number and 1250 is the amount of people added each year followed by x which is the number in years.

Step-by-step explanation: Add the numbers 18x-15+3x-11+4x+1=180 18x-25+3x+4x=180 then you combine like terms and you get, 18x-25+3x+4x=180 25x-25=180 then you add 5 to both sides of the equation 25x-25=180. 25x-25+25=180+25 then you simplify then you add the numbers 25x=205 then you divide both sides of the equation by the same term 25x=205 25x/25 = 205/25 then you simplify, you cancel terms that are in both the numerator and denominator then you divide the numbers and you get, x equals forty one over five.
