Consider JKL below. Determine whether each equation is correct. Select correct or incorrect next to each question.
From the options equation A and D are correct answers.
What are trigonometric ratios?The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
In the given triangle JKL, JK=25, JL=7 and LK=24.
We know that, sin θ= Perpendicular/Hypotenuse
tan θ= Perpendicular/Base
A) Now, sin J=LK/JK
sin J= 24/25
B) tan J=LK/JL
tan J=24/7
C) sin K=JL/JK
sin K=7/25
D) tan K=JL/LK
tan K=7/24
Therefore, from the options equation A and D are correct answers.

2.write the proportion
3.first number answer
4second number answer
help me plss!
Answer:
52:91
Step-by-step explanation:
To find a ratio value you need to think of it more as two numerators that together equal one whole. 4+7 is 11 so that would be the denominator. If the sum is 143, then we divide by 11 since one number is 4/11s of 143, and the other is 7/11s of 143. 143/11=13
now we multiply both:
4(13)=52
7(13)=91
Check:
91+52=143
52/91 simplifies to 4/7 or 4:7

Dan buys a car for £700.
It depreciates at a rate of 5.5% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny where appropriate
Answer:
£469
Step-by-step explanation:
Given the following
Original cost of car = £700.
Depreciation rate = 5.5%
Depreciation amount after 1 year = 5.5% * 700
Depreciation amount after 1 year = 0.055 * 700
Depreciation amount after 6 year =6 * 38.5 = £231
Worth after 6 years = £700 - £231
Worth after 6 years = £469
The correct answer is:
£498.53

Jenny is 9 years younger than Sammie. Five years ago Sammie was 4 times older than Jennie. How old is each now?
Pls Help Need Answer By 7:00.
Jenny is 8 years old and Sammie 17 is years old.
Given that:Jenny is 9 years younger than Sammie.Five years ago, Sammie was 4 times older than Jennie.To find:Current age of Jennie and Sammie
Calculation and Explanation.Let the current age of Jennie be x.
Let the current age of Sammie be y.
Then from given data we have:
[tex]x = y-9\\4(x-5) = (y-5)[/tex]
We'll substitute value of x from equation 1 in equation 2:
[tex]4(y-9-5) = (y-5)\\3y = 51\\y=17[/tex]
Thus, from equation 1 and y = 17, we have:
[tex]x=y-9\\x=17-9\\x=8[/tex]
Thus, Jenny is 8 years old and Sammie 17 is years old.

2k+16=30 i need help with this before March 2nd ASAP
Answer:
k = 7
Step-by-step explanation:
The goal is to solve for the variable k in this problem.
To do this, we need to get k by itself!
2k + 16 = 30
Start by subtracting the 16 over from the left side to the right
2k + 16 - 16 = 30 - 16
Simplify by subtracting 16 from 16 on the left side (which is 0) and 16 from 30 on the right side (which is 14).
2k = 14
Then finish by dividing both sides by 2 to get k by itself.
[tex]\frac{2k}{2}[/tex] = [tex]\frac{14}{2}[/tex]
Simplify by dividing 2 by 2 on the left side (which is 1) and 14 by 2 on the right side (which is 7).
k = 7

1. Tickets to the fair cost $7 for children and $14 for adults. On Wednesday, 178 people enter the fair and collected $1848. What number of children and what number of adults attended?
2. Tickets to the fair cost $5 for children and $11 for adults. On Tuesday, 164 people enter the fair and collected $1270. What number of children and what number of adults attended?
Answer:
1, is So this means the answer is 81 children and 96 adults.
2, 250 $5 tickets and 100 $11 tickets were sold
Step-by-step explanation:
--- To solve this, you can use quadratics. x + y = 177 and 4x + 11y = 1380 are the equations to solve for x and y. 177 is the total amount of people who entered the fair, and 1380 is the total money earned. x is the amount of children entered, while y is the amount of adults entered. If we were to do 4(x + y = 177), the equation would become 4x + 4y = 708. Then, we minus the 2 equations together, eliminating the x so we can solve for y. So, the final equation is 7y = 672, meaning y = 96. If we bring this into the first equation, x + y = 177, we can find that x = 81.

Answer:
b)30 boys c)1425 beats
Step-by-step explanation:
Answer:
Step-by-step explanation:
b and g are the number of boys and girls, respectively.
b:g = 3:4
b = 3x, g = 4x
3x+4x = 70
x = 10
There are 30 boys.
:::::
(380 beats)/(4 minutes) = (380/4 beats)/minute = (95 beats)/minute
15 minutes × (95 beats)/minute = 1425 beats

Write an equation in point-slope form for the line that passes through each point with the given slope (-1,-2) m= 3
Answer:
y + 2 = 3(x + 1)Step-by-step explanation:
The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is: y - y₁ = m(x - x₁)
m = 3
x₁ = -1
y₁ = -2
Therefore the equation:
y - (-2) = 3(x - (-1))
y + 2 = 3(x + 1)Solve the system by graphing.
y = −x + 3
y = −3x − 1

Answer:
A(-2,5)
x= -2 , y=5
Step-by-step explanation:
draw the lines for both equations and that will be by finding any points in the lines:
1. sub any value for x to find y in the equation (y=-x+3) :
When x=0 ⇒ y=-0+3, y=3 (the point is: (0,3)When x=1 ⇒ y= -1 +3 , y=2 (the point is: (1,2)When x=2 ⇒ y=-2+3, y=1 (the point is: (2,1)When x=-1 ⇒ y=-(-1)+3, y=4 (the point is: (-1,4)When x=-2 ⇒ y=-(-2)+3, y=5 (the point is: (-2,5)plot the points in the graph and match them to get the first line for equation(1).
2. sub any value for x to find y in the equation (y=-3x-1) :
When x=0 ⇒ y=-3(0)-1, y=-1 (the point is: (0,-1)When x=1 ⇒ y=-3(1)-1, y=-4 (the point is: (1,-4)When x=2 ⇒ y=-3(2)-1, y=-7 (the point is: (2,-7)When x=-1 ⇒ y=-3(-1)-1, y=2 (the point is: (-1,2)When x=-2 ⇒ y=-3(-2)-1, y=5 (the point is: (-2,5)Now again plot the points in the same graph and match them to get the second line for equation(2).
When you finish you will have two lines drawn in a graph, the solution will be were the two points intercept, and that will be:
A(-2,5)
x= -2 , y=5
(note: you can check your answer by subbing the value of x in both equations and you should get the answer 5 as the value of y)
