Answers
Answer:
x=20
Step-by-step explanation:
If there is a 90° angle, that means the 2 sides connecting it must be the same. Therefore, side x is equal to 20 since it is equal to the other side connecting the angle.

Scarlett has a 12 foot ladder that she is using so she can clean the gutters on her house. If she leans it against the house, making an 80 degree angle with the ground, how high up the house does it reach?
Answers
Scarlet is leaning a 12 foot ladder. When you lean a 12 foot ladder, it is s slanted so we will make 12 our slanted side or hypotenuse. It makes a 80 degree angle after contact with the ground so it will be on the lowest angle on the right. We are asked to find the vertical side or how high up the ground is. We are asked to a angle that is opposite of the given angle which is x .. And we are also given the hypotenuse. We are going to use sin using our SOHCAHTOA
[tex] \sin(theta) = \frac{opposite}{hypotunese} [/tex]
Where there is our given angle.
Let plug it in
[tex] \sin(80) = \frac{x}{12} [/tex]
Multiply 12 by both sides and we get
[tex] \sin(80) \times 12 = x[/tex]

Negative angles are measured in which direction from standard position?
Answers
The negative angles are measured in a clockwise direction.
What are angles?When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the point at which two points come into contact.
An angle can be measured in either direction clockwise or anticlockwise.
The angle measured in the anticlockwise direction is considered a positive angle while the angles measured in the clockwise direction are considered to be negative angles.
Hence, the negative angles are measured in the clockwise direction.

D. No energy transformations are involved while she is going down the hi D
Answers
Answer:
B
Explanation:
the wheels are getting warmer so it would have to be thermal energy, hope this helps :)
Gravitational potential energy is transformed into motion energy ,kinetic energy and thermal energy.
We know that Gravitational potential energy is the potential energy with respect to the gravitational force. To possess gravitational potential energy, the object to be placed in a position in the gravitational field.
What is potential energy?Potential energy of body is the energy generated by virtue of the position of the body. Whereas kinetic energy is generated by virtue of its movement.
Potential energy and kinetic energy together called as mechanical energy. The potential energy is mathematically expressed as;
p = mgh.
Here, g s gravity, h is height and m is the mass.
The gravitational potential energy can be arised in an object due the position in gravitational field. That changes with the change in position and change in height from the ground.
Hence Gravitational potential energy is transformed into motion energy (kinetic energy) and thermal energy.

Divide. -24 divided by 7 Enter your question as a mixed number, in simplified form, in the box. Please hurry! Thank you :D
Answers
Answer:
-3 1/7
Step-by-step explanation:
The required simplified mixed number of -24 divided by 7 is -3 3/7.
To divide -24 by 7, the result is a mixed number in simplified form.
Divide -24 by 7:
-24 ÷ 7 = -3.428571...
Simplify the result as a mixed number:
To write the mixed number, we take the whole number part, which is -3, and the fractional part, which is the remainder after dividing.
The remainder is approximately 0.428571... (it goes on infinitely), but we'll round it to the nearest fraction for simplicity.
Approximately, 0.428571... is closest to 3/7.
So, the simplified mixed number is -3 3/7.

A coin contains 9 99 grams of nickel and 16 1616 grams of copper, for a total weight of 25 2525 grams
Answers
Answer:
64%
Step-by-step explanation:
A coin contains 9 grams of nickel and 16 grams of copper for a total weight of 25 grams.
What percentage of the metal in the coin is copper
Solution:
The total weight of the coin = weight of copper in coin + weight of nickel in coin
The total weight of the coin = 9 g + 16 g = 25 g
The percentage of copper in the coin is the ratio of the weight of copper in the coin to the total weight of the coin expressed in percentage. It is given by the formula:
The percentage of copper in the coin = (weight of copper in the coin / total weight of the coin) * 100%
The percentage of copper in the coin = (16 g / 25 g) * 100% = 64%

Trevon and Riggs are brothers.
Trevon is 7 years older than Riggs.
Their combined age is 49.
How old is Trevon
Answers
Answer:
Trevon is 28 years old
Step-by-step explanation:
Riggs =x
Trevon =7+x
7+x+x=49
7+2x=49
2x=49-7
2x=42
x=21
Trevon is 21+7= 28 years old
T = 7 years older than R which can be written as T = R + 7
Their combined age is 49.
Therefore, T + R = 49
We need to find Trevon’s age (T.)
We can substitute R + 7 for T in the equation
T + R = 49.
We have:
R + 7 + R = 49
Now solve.
2R + 7 = 49
2R = 42
R = 21
We have found Riggs’ age which is 21.
Add 7.
Trevon’s age is 28.
