Answer:
40 cm
Step-by-step explanation:
In the right triangle PNO:
∠N = 90°PO = 100cm (the hypotenuse of the triangle)∠P = 23°∠O = 90° - 23° = 67°side NO is adjacent to ∠OBy definition:
cos(β) = adjacent/hypotenuse
Replacing with data and solving for NO:
cos(∠O) = NO/PO
2/5 = NO/100
NO = (2/5)*100
NO = 40

Kathi is trying to buy herself a phone. She is deciding between Phone Plan A and B.
phone plan A = retail price : $500 cupon : 25% off sale price : x
phone plan B = retail price : $435 cupon : 50% off sale price : x
How can she find out the monetary amount of the discount for Phone Plan A?
a. x/500 = 24/100
b. 25/500 = x/100
c. x/25 = 100/500
PLSSS EXPLAIN HOW U GOT THE ANSWER
Answer:
x/25 = 100/500
Step-by-step explanation:
so, to find the MA, you'd do x/25 since you're trying to find out the discount for Phone Plan A. 25 is the 25% of the Phone Plan A

First answer :D
Have a great day!Answer:
x = 5
Step-by-step explanation:
Now to solve for our equation:
110 - 4x = 130 - 8x
Subtract 110 from both sides: (110 - 110) - 4x = (130 - 110) - 8x
Simplify: -4x = -8x + 20
Add 8x to both sides: (-4x + 8x) = (-8x + 8x) + 20
Simplify: 4x = 20
Divide both sides by 4: (4x / 4) = (20 / 4)
Simplify: x = 5

Step-by-step explanation:
This is an unidentified triangle or a scaleneThe equation: 14^2+x^2=q^2 This equation is for the pathagoern theorem. (If you have not learned it put a thanks and ask the question about it) This equation 14^2+x^2=q^2 = 14^2=x^2-q^ = x^2= 32 = x = 16I hope this helps!A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
can someone help? im not sure about this questons and its getting me so stressed out :( pls help :(

2. Value of y= 28 cm
Picture 3:- [Picture 3 is cropped so I'm guessing its the last one so imma answer those questions :D]
1. Scale factor= 5 (Again I'm not sure but its my best guess)
2. Value of z= 5
Picture 4:-

It'll help you understand how we solve these questions
Well anyways i hope this clears your concepts :D
Answer:
Step-by-step explanation:
EH is 12cm as the shape has been enlarged by scale factor two (all sides have been multiplied by 2).
Angle G remains the same at 55 degrees.
PART A
Scale factor for the triangle = 1/4
Value of y = 28cm
3) z = 5, scale factor = 5

Answer:
So to find the volume of triangle prism,
Find area of triangle = \(\frac{1}{2} (5)(3)=\frac{15}{2} =7.5in^{2}\)
Then find the total volume of triangle prism= 7.5×6=45in³
Volume of triangular prism = 45in³
Now to find the volume of the rectangular piece,
Volume=width×height×length
= 7×3×16
= 336 in³
Volume of rectangular piece = 336in³
Total area= 45in³+336in³=381in³

Hello, could anyone please help me with this problem.
Maria currently has 465 dollars in her account. She withdrew money for $250 and $175. If she spends $45 to put gas in her car, How much money will Maria have in her account?
Answer:
40$
Step-by-step explanation:
if maria has 465$ in her account and she withdrew 250$ makes 215 but it also says she withdrew 175 so 215 subtract 175 makes 40 dollars if she uses 45 dollars to fill her car up she still only has 40 dollars i hope this helps
Answer: $40
Step-by-step explanation: If Maria has 465 dollars and withdraws takes out subtracts $250 she has $215 after that she takes out or subtracts $175 so than she has $40. I think the answer is $40 but I am not so good at math so I'm not sure

Answer:
\(\huge\boxed{\sf x =28 \textdegree}\)
Step-by-step explanation:
Given that,
∠IAK = 62°
∠IAK + ∠IAD = 90° (Complementary angles)
62 + ∠IAD = 90°
Subtract 62 to both sides
∠IAD = 90 - 62
∠IAD = 28°∠IAD = ∠ACB (Corresponding angles are equal)
So,
∠ACB = 28°∠ACB = ∠GCJ (Vertically opposite angles are equal)
So,
28° = x°
OR
x° = 28°\(\rule[225]{225}{2}\)
Answer:
28 degrees
Step-by-step explanation:
If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.
--> Angle LAJ is 62 degrees
If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.
We know that in a triangle, there are three angles, and the angle measures combined equals 180.
Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.
--> 180 - 90 - 62 = 28
--> Angle BCA = 28 degrees
Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.
Angle x = 28 degrees

Step-by-step explanation:
You find range by subtracting the lowest amount from your data by the highest amount. The highest number in Ms. Gambino's class is 12, and the lowest is 5.
\(12-5=7\) This is the range of Ms. Gambino's class
The highest number in Mr. Joe's class is 10 and the lowest is 5
\(10-5=5\\\) This is the range of Mr. Joe's class.
Therefore, the range in Mr. Joe's class is less than the range of data in Ms. Gambino's class.
