In ΔIJK, i = 25 inches, j = 46 inches and k=24 inches. Find the measure of ∠J to the nearest degree.
Answer:
[tex]<J= cos^{-1} ((I^{2} + K^{2} - J^{2} )/(2IK))\\<J=cos^{-1} (\frac{(25^{2} + 24^{2} - 46^{2}}{(2(25)(24)})\\<J=139.685^{o}[/tex]
the measure of ∠J in ΔIJK is approximately 104 degrees.
What are the properties of a Triangle?The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
To find the measure of ∠J in ΔIJK, we can use the Law of Cosines, which states that:
c² = a² + b² - 2ab cos(C)
where c is the side opposite the angle we want to find (in this case, side j), and a and b are the other two sides.
Substituting the given values, we get:
j² = i² + k² - 2ik cos(∠J)
Solving for cos(∠J), we get:
cos(∠J) = (i² + k² - j²) / 2ik
Substituting the given values, we get:
cos(∠J) = (25² + 24² - 46²) / (22524)
cos(∠J) = -0.2395833...
Using a calculator, we can take the inverse cosine of this value to find the measure of ∠J:
∠J ≈ 103.8 degrees
Rounding to the nearest degree, we get:
∠J ≈ 104 degrees
Therefore, the measure of ∠J in ΔIJK is approximately 104 degrees.

Step-by-step explanation:
We need to either divide the second equation by 3 or -3 to get y or -y, where we would then subtract or add both equations OR multiply the first equation by 3 or -3 to get 3y or -3y, where we would then subtract or add both equations.

Answer:
Interpret the meaning of the expression 2x – 3. The expression 2x – 3 represents The variable x represents.
Step-by-step explanation:
Answer:
The x represents how many songs Sabrina has because if you are saying Nicolas has three less than twice as many as her then you are doubling the amount of songs Sabrina has and you're subtracting 3 from that to get how many songs Nicolas has. Let's say Sabrina has 29 songs. Now we are trying to find out how many songs Nicolas has. 2x-3. 2(29) - 3. 58-3. Nicolas has 55 songs if Sabrina were to have 29. I really hope this helped :)

Answer:
option C is correct answer ..
Step-by-step explanation:
angle A + angle B + angle C = 180° ( by angle sum property of triangle )
3x + 4x-19+ 3x -1 = 180
10x + -20 = 180
10x = 180 +20 = 200
x = 200/10 = 20 °
angle A = 3× 20 = 60 °
angle B = 4× 20 - 1 9 = 61 °
angle C = 3× 20 -1 = 59 °
angle B is greatest so side opposite to it will be greatest in length ....so length of AC is greatest ....
so option C is the correct answer of this question ...

You earned $1,200.50 over a three-week period. How many hours did you work?
Carl hires a caterer to provide food for his birthday. The caterer
charges him $250 for food and supplies and $25 per hour to serve during
the party. Carl ends up paying $325 total. How many hours did the caterer
serve? Use 25x+250=325 as your equation to solve.
Answer:
3 hours
Step-by-step explanation:
25x = 325-250
25x = 75
x = 75/25
x= 3 hours
Answer:
3 hours
Step-by-step explanation:
You must first subtract 250 from 325. THis gives 75 left over. Then divide that by 25 to find x. This gives 3.
Which correlation coefficient will most likely describe the relationship between frequency of teeth brushing and the number of cavities one gets?
Answer:
The correct approach is "-62". A further explanation is described below.
Explanation:
A dependent variable could be seen since the blackheads become triggered whenever some substance or material is deposited between some of the teeth. Humans don't brush their teeth frequently, but there is still a significant possibility of decay, so cavities differ depending upon whether the specific teeth become brushed.A factory worker earns $150 each day plus $5.25 for each widget that he makes. If he earned $370.50 for one day of work, how many widgets did he make?
Answer:
42
Step-by-step explanation:
To find out how many widgets he made, you need to find out how much money was earned from all the widgets he made. You know that one day only earns $150 without any widgets but the factory worker earned $370.50 so the difference would be the amount of money earned from the extra widgets.
Amount of money earned from widgets = $370.50 - $150
= $220.50
You know each widget costs $5.25, so you can find out how many widgets were made.
No. of widgets made = $220.50 ÷ $5.25
= 42
Answer:
42
Step-by-step explanation:
use the linear equation
y = 5.25x +150 x represents the amount of widgets made and y is the amount earned each day
plug in 370.50 for y then solve for x
370.50 = 5.25x + 150
220.50 = 5.25x
42 = x
so he made 42 widgets

Answer:
72.5 is greater than 1 * 50 (50) but less than 2 * 50 (100)
Step-by-step explanation:
First, let's figure out what 145% of 50 is. A percentage is a ratio or fraction of 100. So, 1 is 100% .5 is 50% .25 is 25%. Now that being said, let's find out how to find the percentage of a number.
To do that, you need to multiply the percentage & 50. So...
[tex]1.45 * 50=72.5[/tex]
Now, lets compare with the other options.
72.5 is greater than 2*50 (100) but less than 3 * 50 (150) ❌
72.5 is greater than 3 * 50 (150) ❌

A single card is drawn from a standard 52 card deck. Work out the probability of choosing "an ace". Give your answer in its simplest form.
Answer:
total number of ace=4
probability of getting an ace =4/52
=1/13
hope it helps you
The probability of choosing "an ace" from the pack of 52 cards is 1/13.
ProbabilityWhat is probability?In mathematics, a random event's occurrence is called probability. The range of the value is 0 to 1.
Formula for probability:
By simply dividing the favourable number of outcomes by the entire number of possible outcomes, one can use the probability formula to determine the likelihood of an event.
Probability = Number of favourable outcome/ Number of total outcome
Calculation for choosing an ace:
The total number of cards present in the standard deck of cards is 52.
Total number of ace present in the pack is 4.
So, the probability of getting an ace is = total number of ace /total number of card is deck
Probability = 4/52
Probability = 1/13
Therefore, the probability of getting an ace from the pack of well shuffled cards is 1/13.

A kite is flying so that it is 65 m high and above a point 57m from the person holding the string. What is the length of the string correct to 3 decimal places?
Answer:
86.452 m
Step-by-step explanation:
I've attached an image showing the position of the person and the string and the kite.
From the image attached, we can see that the length of the string can be calculated from pythagoras theorem since the triangle is a right angled triangle.
Thus, let length of string be denoted as s.
s = √(65² + 57²)
s = √7474
s ≈ 86.452 m

Hana makes and sells knit scarves. She will charge $12 for each scarf she sells at the craft fair next week. She will pay a $25 fee for the use of a booth at the fair. Write an expression to determine Hana's profit for selling "s" scarves after paying the fee for the use of the booth.
Answer:
$12s - $25
Step-by-step explanation:
Given that:
Amount charged per scarve = $12
Cost of booth used = $25
Profit made for selling 's' scarve after paying for booth
Profit = Revenue - Expenditure
Revenue = cost per scarve * number of scarves sold
Revenue = $12 * s
Revenue = 12s
Expenditure = cost of booth
Expenditure = $25
Hence,
Profit made = $12s - $25
