Answer:
x = 4JT = 18Step-by-step explanation:
Given three points J, C and T on a line, if J is between C and T then;
CJ + JT = CT.
Given CJ=8x+5, CT=55, and JT=4x+2, substituting this parameters in the equation above will give;
[tex](8x+5)+(4x+2)= 55\\8x+4x+5+2 = 55\\12x+7 = 55\\12x = 55-7\\12x = 48\\ x = \frac{48}{12} \\x = 4[/tex]
SInce JT = 4x+2
[tex]JT = 4(4)+2\\JT = 16+2\\JT = 18[/tex]

In ΔLMN, the measure of ∠N=90°, ML = 97, NM = 65, and LN = 72. What ratio represents the tangent of ∠L?
Answer:
tan ∠L = 65/72
Step-by-step explanation:
The tangent ratio is:
tan of angle x = opposite/adjacent
Looking from the perspective of angle L, find the opposite side.
This side is MN, measuring 65 units.
opposite = 65
Now let's find the adjacent side.
This side is LN, measuring 72 units.
adjacent = 72
Therefore, the tangent ratio of angle L is 65/72.
Answer:
65/72

In a group of Year 9 students, the ratio of boys to girls is 9 : 7. There are 4 more boys than girls in this group. How many students are in this group altogether?
Answer: 32
Step-by-step explanation:
There are 18 boys and 14 girls (4 more boys than girls. 32 students total.
If the ratio of boys to girls is 9 : 7, there are 32 students in this Year 9 group altogether.
Let's denote the number of boys as "9x" and the number of girls as "7x" since the ratio of boys to girls is 9:7. We are also given that there are 4 more boys than girls, so we can set up an equation:
Number of boys = Number of girls + 4
9x = 7x + 4
Now, we can solve for "x":
9x - 7x = 4
2x = 4
x = 2
Now that we have the value of "x," we can find the number of boys and girls:
Number of boys = 9x = 9 * 2 = 18
Number of girls = 7x = 7 * 2 = 14
Finally, to find the total number of students in the group, we add the number of boys and girls:
Total number of students = 18 (boys) + 14 (girls) = 32.
The ratio of boys to girls is 9:7, and there are 4 more boys than girls.

what is the circumference of a circle witha radius of 4 in
25.12 in or 8π
Step-by-step explanation:
Since you didn't specify whether or not to leave pi or to make it be 3.14, I did both.
The formula for the circumference of a circle is...
[tex]C=2\pi r[/tex]
So...
[tex]C=2*3.14*4[/tex]
C = 25.12 in

a Fair coin is tossed 4 times. What is the probability of not getting all heads?
Answer:
15/16
Step-by-step explanation:
The probability of not getting all heads is
1 - P(all heads)
P (all heads) =P(heads) * P(heads)* P(heads) * P(heads)
1/2* 1/2 * 1/2 * 1/2 = 1/16
1 - 1//16 = 15/16

find the point that lies on the line described by the equation below. y - 3 = 3 (x - 9)
Answer: D
Step-by-step explanation: (9,3) is the given point in the equation where y-y1=m(x-x1)
Answer:
D. (9, 3)
Step-by-step explanation:
You can solve figure this out by plugging in the coordinates. The best guess would be that the answer is "D," and we can check:
y - 3 = 3(x - 9)
3 - 3 = 3(9 - 9)
0 = 3(0)
0 = 0
Since the answers match, answer "D," is correct.

(a,b) (less, greater)
Answer: The diameter of Pool A is 7.32 meters. So, the diameter of Pool B is greater, and the circumference is greater by 0.56 meters.
Step-by-step explanation:
The diameter of a circle is double its radius.
Pool A has a radius of 12 feet - double that would be 24 feet, its diameter.
Next, convert this to meters:
[tex]24 * \frac{0.305}{1} = 7.32[/tex]
The diameter of pool A is 7.32 meters.
The diameter of pool B is 7.5 meters.
The diameter of pool B is greater.
You can calculate the circumference of a circle by using this formula:
[tex]C = 2\pi r[/tex], where r is the radius.
Divide 7.5 by 2 to get your radius of Pool B, which is 3.75, and solve for C:
[tex]C = 7.5\pi \\\\C = 23.561[/tex]
Rounding to the nearest hundredth, the circumference for pool B is 23.56 meters.
Do the same thing for pool A:
[tex]C = 7.32\pi \\\\C = 22.996[/tex]
Circumference for pool A rounds to 23 meters.
Answer:
the diameter of pool a is 24. so, the diameter of pool b, is greater, and idk the rest

Joaquin used 1-3/6 cups of apple juice and 1-4/6 cups of orange juice in a recipe for punch. How much juice did Joaquin use?Solve this problem any way you choose.
Answer:
The answer is 3 and 1/6 cups.
Step-by-step explanation:
If Joaquin used 1 and 3/6 cups of apple juice and 1 and 4/6 cups of orange juice for the punch, there is a total of 2 cups and the fractions can be added as their denominators are the same.
3/6 + 4/6 = 7/6 cups

13 sin(2x) - 3 = 3
Answer:
The answer is A
Step-by-step explanation:
Answer:
0.24+n*pi and 1.33+n*pi
Step-by-step explanation:
First you add three to both sides to get:
13sin(2x)=6
Then you divide by thirteen to both sides to get:
sin(2x)= 6/13
Next, you use a calculator to perform the inverse of sine to both sides, which is arcsin, and cancels out the sin.
arcsin(sin(2x))= arcsin(6/13) -> 2x= arcsin(6/13)
Arcsin(6/13)= approximately 0.48. But besides 0.48, there is another solution, because the y value of 6/13 can have two possible x values, both in quadrant one and two. We found the quadrant one value. The quadrant two value is just pi-0.48=2.66.
So, if we add two pi (360 degrees) to both of these solutions for n amount of times, then on a graph, we would end up on the same point every time. Each of those revolutions around the graph is one solution. These are the solutions:
2x= 0.48+n*2pi -> 0.24+n*pi
2x=2.66+n*2pi -> 1.33+n*pi
