Step-by-step explanation:
If the two triangles are similar, that means their sides are proportional to each other.
JK = 15JL = 15 + 6 = 21JM = 14The proportion would look like this:
\(\frac{JK}{JL} =\frac{JN}{JM}\\\)
Substitute in the values:
\(\frac{15}{21} =\frac{JN}{14}\)
Cross-multiply and solve for JN:
\(21*JN=15*14\\JN=\frac{15*14}{21} =\frac{210}{21} =10\)
Answer:
10 inches
Step-by-step explanation:
JM=14<JL=21
And you know that JN=X<JK=15
You also know that JM=14>JN=x
KL=6 so NM=4
JM= (14) - NM (4)= 10

pls help me
Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Monique made
batches of soup.
Answers
Answer:
Number of batches of soup = 8 2/3 batches
Step-by-step explanation:
Each batch of soup = 3/4 pounds of potatoes
Total pounds of potatoes available = 6 1/2 pounds
How many batches of soup did Monique make?Number of batches of soup = Total pounds of potatoes available / Each batch of soup
\(= 6\dfrac{1}{2} \ \text{pounds} \div \dfrac{3}{4} \ \text{pounds}\)
\(= \dfrac{13}{2} \div \dfrac{3}{4}\)
\(= \dfrac{13}{2} \times \dfrac{4}{3}\)
\(= \dfrac{13\times4}{2\times3}\)
\(= \dfrac{52}{6}\)
\(= 8 \dfrac{4}{6}\)
\(= 8 \dfrac{2}{3}\)

Nellie just bought a new perfume called Rose Honey. It comes in a bottle shaped like a rectangular prism. The bottle is 4 centimeters long, 2 centimeters wide, and 7 centimeters tall, but the perfume's box says the bottle only contains 45 milliliters, or 45 cubic centimeters, of perfume.
How many more milliliters of perfume would it take to completely fill the bottle?
Write your answer as a whole number or decimal. Do not round.
Answers
Answer:
It would take 11 milliliters of perfume to completely fill the bottle.
Step-by-step explanation:
The volume of the rectangular prism-shaped bottle can be calculated by multiplying its length, width, and height. Therefore, the bottle's volume is:
4 cm x 2 cm x 7 cm = 56 cubic centimeters
The bottle contains 45 cubic centimeters of perfume, so the amount of additional perfume needed to completely fill the bottle is:
56 cubic centimeters - 45 cubic centimeters = 11 cubic centimeters
Therefore, it would take 11 more milliliters of perfume to completely fill the bottle. Since 1 cubic centimeter is equal to 1 milliliter, the answer is simply 11 milliliters.
7 times 2 times 4 - 45
56-45= 11

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

Answer:
Answer: a is -2
Step-by-step explanation:
\( - (5a + 6) = 2(3a + 8)\)
open the brackets [ distribution ] :
\( - 5a - 6 = 6a + 16\)
group like terms together:
\( - 5a - 6a = 16 + 6 \\ - 11a = 22\)
divide both sides by -11 :
\( \frac{ - 11a}{ - 11} = \frac{22}{ - 11} \\ \\ a = - 2\)
