The ratio of the angle measures of a triangle are 1:2:2. What type of triangle is this?
acute triangle
right triangle
obtuse triangle
equiangular triangle
Answer:
The answer is NOT D, because clearly the angle measurements are not EQUAL. So cross that off. My best guess would be A, acute triangle. Usually for that the two angles are shown as the same and the top angle is usually smaller. That's just from picturing it in the head.

What is the value of b 3.2 = 4/5 ( b - 5 )
The value of b in the equation [tex]\( 3.2 = \frac{4}{5}(b - 5) \)[/tex] is 9.
To solve for b in the equation [tex]\(3.2 = \frac{4}{5}(b - 5)\)[/tex], we'll first distribute [tex]\(\frac{4}{5}\)[/tex] across b - 5:
[tex]\[3.2 = \frac{4}{5}b - \frac{4}{5} \times 5\]\[3.2 = \frac{4}{5}b - 4\][/tex]
Next, let's isolate the term containing b by adding 4 to both sides:
[tex]\[3.2 + 4 = \frac{4}{5}b\]\[7.2 = \frac{4}{5}b\][/tex]
Now, to solve for b, we'll multiply both sides by [tex]\(\frac{5}{4}\)[/tex] to isolate b:
[tex]\[b = 7.2 \times \frac{5}{4}\]\[b = 9\][/tex]
So, the value of b is 9.

On a recent day 8 euros were worth 9 dollars and 24 euros were worth 24 dollars write an equation of the form y = kx
On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.
Answer:y = 1.125x is the equation to show the relationship between the number of euros and the value in dollars.
Solution:Given that On a recent day 8 euros were worth 9 dollars and 24 euros were worth 24 dollars
Let "y" be the value in dollars
Let "x" be the number of euros
We have to write a equation in form of y = kx
8 euros were worth 9 dollars
"k" is found as follows:
[tex]k = \frac{\text{value in dollars}}{\text{number of dollars}}[/tex]
[tex]k = \frac{9}{8}[/tex]
Therefore, equation of y = kx is given as:
[tex]y = \frac{9}{8}x[/tex]
[tex]y = 1.125x[/tex]
To check the equation, use the another given value
24 euros were worth $27
[tex]y = 1.125 \times 24\\\\y = 27[/tex]
Hence the equation y = 1.125x is correct
f(x)= x2-5x+2. Find f(-4)
Answer:
f ( 4 ) = 18
Step-by-step explanation:
Explanation:
f ( x ) = 5 x − 2
Replace 4 instead of x to find f ( 4 )
f ( 4 ) = 5 ( 4 ) − 2 = 20 − 2 = 18
The value of f(-4) for the function f(x) = x^2 - 5x + 2 is 38.
Explanation:To find the value of f(-4) for the function f(x) = x^2 - 5x + 2, you substitute -4 for x in the function.
It looks like this:
f(-4) = (-4)^2 - 5(-4) + 2
First, you square -4, which is (-4)^2 = 16.
Then, you calculate -5 times -4, which is 20.
Finally, you add 2 to the result.
So, f(-4) is equal to:
f(-4) = 16 - 20 + 2 = 38
The final answer is 38.

The relationship between the distance traveled by a car and the amount of gas in the car is inverse. As the distance increases, the gas decreases
Explanation:The relationship between the distance traveled by a car and the amount of gas in the car is inverse. This means that as one quantity increases, the other decreases. In this case, as the distance traveled by a car increases, the amount of gas in the car decreases, because the car uses gas to move. In other words, the more you drive, the less gas you have left in your car.

is a solution to the system because it
The ordered pair
makes both equations true.
The ordered pair (-3, 1) is not a solution to system because it makes at least one of the equations false
Solution:
Given system of equations are:
x - 4y = 6 ------- eqn 1
3x + y = -8 ------------ eqn 2
Given ordered pair is (-3, 1)
We have to check if the options are true
Let us substitute (x, y) = (-3, 1) in eqn 1
[tex]-3 - 4(1) = 6\\\\-3 - 4 = 6\\\\-7\neq 6[/tex]
Thus the given ordered pair (-3, 1) did not satisfy the first equation
Substitute (x, y) = (-3, 1) in eqn 2
[tex]3(-3) + 1 = -8\\\\-9 + 1 = -8\\\\-8 = -8[/tex]
Thus the given ordered pair (-3, 1) satisfied the second equation
But for a ordered pair to be a solution to system of equations, it must satisfy both the equations
Thus the ordered pair (-3, 1) is not a solution to system because it makes at least one of the equations false
Which answer represents the series in sigma notation? −5+(−1)+3+7+11
The series in sigma notation is: representing terms increasing by 4 starting from -5.
To represent the series in sigma notation, let's first examine the pattern of the terms.
The given series starts with -5 and each subsequent term increases by 4. We can express this pattern using the formula:
[tex]\[ a_n = -5 + (n - 1) \times 4 \][/tex]
Here, [tex]\( a_n \) represents the \( n \)th term of the series[/tex].
Now, let's break down the components of the formula:
-[tex]\( -5 \) is the initial term of the series.- \( (n - 1) \) accounts for the position of each term in the series. When \( n = 1 \), \( (n - 1) = 0 \), so the first term is \( -5 \). As \( n \) increases, \( (n - 1) \) increases by 1, causing the series to increase by 4 each time.- \( 4 \) is the common difference between consecutive terms in the series.[/tex]
Next, we represent the series using sigma notation:
[tex]\[ \sum_{n=1}^{5} (-5 + (n-1) \times 4) \][/tex]
This notation indicates that we sum up the expression [tex]\( -5 + (n-1) \times 4 \) for \( n \)[/tex] ranging from 1 to 5, which covers all the terms of the given series.
In summary, the series is represented in sigma notation as described above, capturing the pattern of increasing terms starting from -5.
factorise 9f²-12f plus 4
Answer:
(3f - 2)²
Step-by-step explanation:
Given
9f² - 12f + 4
Consider the factors of the product of the coefficient of the f² term and the constant term which sum to give the coefficient of the f- term.
product = 9 × 4 = 36 and sum = - 12
The factors are - 6 and - 6
Use these factors to split the f- term
9f² - 6t - 6t + 4 ( factor the first/second and third/fourth terms )
= 3f(3f - 2) - 2(3f - 2) ← factor out (3f - 2) from each term
= (3f - 2)(3f - 2)
= (3f - 2)²
Answer:
9f² - 12f + 4 = (3f - 2)²
Step-by-step explanation:
9f²-12f+4 =
= (3f)²-2×(3f)×(2)+2²
= (3f-2)²

Olivia goes shopping with a friend and notices her friend's fashionable winter boots. She thinks about the recent cool weather and realizes she needs to buy a pair. In which stage of the consumer purchase decision process was Olivia when she had this realization?
Answer:
Problem Recognition Stage (the first stage)
Explanation:
The "Consumer Buying Decision Process" consists of 5 stages. These are: Problem Recognition, Information Search, Evaluation of Alternatives, Purchase Decision and Post-Purchase Evaluation. This information is commonly used by marketing businesses in order to know the habit or behavior of people upon buying goods and services.
Olivia's situation above is in the "Problem Recognition" stage. This is the first stage of the process. She realizes that she needs the winter boots because of the cool weather and thus, she realizes that she has a need or a problem that she wanted to solve. Buyers recognize this problem as a gap in their needs, thus they want to fill it immediately once they recognize it. This will be followed by "Information Search," a time whereby she'll consider some options in buying boots.
Thus, this explains the answer.

The total of 3 games is $38.97 . Each game costs the same amount. Write an equation that can be used to determine n , the cost of 1 game
Answer:
Step-by-step explanation:
3games cost38.97 so you have to divide 38.97divided by 3=12.99 so each game was 12.99 a game
To determine the cost of 1 game, set up an equation: 3n = $38.97. Divide both sides of the equation by 3 to isolate n. The cost of one game is $12.99.
Explanation:To find the cost of one game, we can set up the equation 3n = $38.97based on the given information. where n represents the cost of one game. Since each game costs the same amount, we can write the equation:
3n = $38.97
Divide both sides of the equation by 3:
n = $38.97 / 3
Dividing both sides of the original equation by 3 is a way to undo the multiplication by 3 on the left side, thereby isolating the variable n.
When we perform this division, we find that n is equal to $12.99.
n = $12.99
Therefore, the cost of one game is $12.99.
