2) 20% decrease
Work:
1)
-subtract the larger # from the smaller # to figure out what the change was.
[tex]8.8 - 6.5 = 2.3[/tex]
-divide 2.3 by the orriginal ammount (8.8) to find your answer as a decimal
[tex]2.3 \div 8.8 = 0.261[/tex]
-take 0.261 and multiply it by 100 to have your answer as a percent
[tex]0.2614 \times 100 = 26.1[/tex]
-if the original number increased than it is percent increase and if the original number decreased than it is percent decrease
2)
-subtract the larger # from the smaller # to figure out what the change was.
[tex]15 - 12 = 3[/tex]
-divide 2.3 by the orriginal ammount (15) to find your answer as a decimal

-take 0.2 and multiply it by 100 to have your answer as a percent
[tex]0.2 \times 100 = 20[/tex]

Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios.
The longest side of a right triangle is called the hypotenuse and the other two sides are the legs.
Selecting any of the acute angles as a reference, we identify an adjacent leg and an opposite leg. The trigonometric ratios are defined upon those sides.
Sine Ratio
[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
Let's focus on the angle θ. Its opposite leg is 8 cm and the hypotenuse is 10 cm, thus:
[tex]\displaystyle \sin\theta=\frac{8}{10}[/tex]
Simplifying:
[tex]\boxed{\displaystyle \sin\theta=\frac{4}{5}}[/tex]
2x+3y=12 Complete the missing value in the solution to the equation. (_,8) I NEED HELP QUICK
Answers
Answer:
-6 is the missing value.....
Answer:
(-6, 8); the missing value is -6
Step-by-step explanation:
First, you need to solve the given equation for x
1: 2x + 3y = 12 (Given)
2: 2x = -3y + 12 (Subtract 3y from both sides to isolate x)
3: x = -1.5y + 6 (Divide both sides by 2)
Now, you can solve for the missing x in the solution set (x, 8):
where x = -1.5y + 6 and y = 8,
x = -1.5(8) + 6
x = -12 + 6
x = -6
So, the missing value is -6

The triangle proportionality theorem only applies to right triangles.
A.) False
B.) True
Answers
Answer:
A.) False
Step-by-step explanation:
The triangle proportionality theorem can apply to all triangles, because if a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally. This situation does not just apply to right triangles.

Answers
Step-by-step explanation:
(x - 3 ) (2x + 4) = 0
Either
x - 3 = 0
Therefore x = 3
Or.,
2x + 4 = 0
2x = - 4
x = - 4 /2
Therefore x = -2
Now the value of x is 3 or - 2.
Hope it will help :)♥

pls answer quickly thanks :)
Answers
Answer: There are 75 Adults in the supermarket ask me why if you want a full on explanation. The full on reason of why it is 75 is because if you have a ratio of 1:5 and you now the one is for the kids and it is 15. Then you add 15 from 1 until you get to the 5th ratio. Hence, it brings you all the way to 75 adults. I hope this helped you, and anyone else

Step-by-step explanation:
The (x+5) can cancel
Then in the numerator (x^2-25) can be factored into (x-5)(x+5) through difference of squares.
Then in the denominator the (x-5)^2 can be stretched out to (x-5)(x-5)
Lastly the (x-5) on the top and bottom will cancel resulting in result B

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses
b. 2x - 7 and the opposite of 2x
Answers
Answer :
Sum = 2x-7 + (-2x) and equivalent expression = -7
Step-by-step explanation:
First number is (2x-7) and other number is opposite of 2x i.e. (-2x).
We need to write the sum of 2x - 7 and the opposite of 2x
Opposite of 2x is (-2x)
Sum means to add the number :
2x-7 + (-2x)
Removing parentheses,
2x-7 - 2x
Taking like terms together,
2x-2x-7= 0-7
= -7
Hence, the answer is -7.

The dots above -10 and 10 are not shaded in meaning those x values do not count towards the domain meaning we will use parenthesis instead of brackets for interval notation or no equal to signs in inequality notation.
