If m∠1 = 123°, find m∠3:

Answer:

I think the answer might be true

Step-by-step explanation:

Supplementary angles add up to 180 degrees. When the angles are placed next to each other, they should add up to 180. Let's try it... 130+50 = 180. Therefore, these angles are supplementary.

Also, for extra help, 180-degree angles make a straight line, like this one. When you get stuck, you can always refer to websites such as Khan Academy for practice and explanations. (https://www.khanacademy.org)

The simplest form of (4a + 8b) / 12 is (a + 2b) / 3.

Given is an expression (4a + 8b) / 12, we need to simplify it in simpler form,

To simplify the expression (4a + 8b) / 12, you can divide both the numerator and the denominator by their greatest common divisor (GCD) to reduce the fraction to its simplest form.

First, let's find the GCD of 4 and 12. The factors of 4 are 1, 2, and 4, and the factors of 12 are 1, 2, 3, 4, 6, and 12.

The largest number that appears in both sets of factors is 4, so the GCD of 4 and 12 is 4.

Dividing both the numerator and the denominator by 4, we get:

(4a + 8b) / 12 = (4(a + 2b)) / (4 x 3)

Canceling out the common factor of 4:

(4(a + 2b)) / (4 x 3) = (a + 2b) / 3

Therefore, the simplest form of (4a + 8b) / 12 is (a + 2b) / 3.

Answer:

Step-by-step explanation:

Put x = 4, y = -5 and z = 2 to the expression 3x² - 4y + xz and use PEMDAS:

3(4)² - 4(-5) + (4)(2)

= 3(16) + 20 + 8

= 48 + 20 + 8

= 76

Answer:

44

Step-by-step explanation:

Alright let’s do this!

Expression: 5x^2 - 3y and x = 4, y = 12

First let’s plug in the missing values of x and y!

5(4)^2 - 3(12)

Then, get rid of exponent! From this point forward follow PEMDAS

5(16) - 3(12)

80 - 36 =

Answer:

1 ft is equals to 12 in

the ramp is 12 inches tall 1 ft tall

A ramp measures 6 ft long

applying the Pythagorean theorem

c²=a²+b²

where

c =6 ft long

a = horizontal distance

b = 1 ft tall

[tex]a^2= c^2 -b^2 = 36 -1 =35\\a=\sqrt{35}=5.92ft[/tex]

Horizontal distance = 5.92 ft

Answer:

Angle 1: 65°

Angle 2: 65°

Angle 3: 50°

Step-by-step explanation:

The sum of 3 angles in a triangle should always be 180°. If it is not 180° all together then it isn't a triangle. So I did 180-50=130 and 130÷2=65 so I chose 65°

Answer:

E = 700c + 100 and 21 cars

Step-by-step explanation:

Let c be the number of cars that Amy sells. The initial salary that Amy gets is 100, no matter how many cars that Amy sells. However, she also makes 700 dollars for every car she sells, or c. Therefore, we have the equation:

E = 700c + 100

with E representing how much money Amy gets. We use this equation for part B. She must make 14800 dollars, which we substitute for E, because that is how much she makes. Therefore, we have:

14800 = 700c + 100.

We solve this equation and get c = 21, so Amy has to sell 21 cars.

Answer:

To earn a total of $14,800 Amy would need to sell 21 cars (Read explanation for equation)

Step-by-step explanation:

$700 per sale of 1 car

$100 Bonus (1 time)

c=Cars

E=Earned

Equation:    E=(700•c) +100

To find how many cars amy would need to sell to reach 14,800, Replace "E" With 14800

14800 = (700•c) +100

Answer:Since the volume of a cylinder formula involves the radius, you can solve for the radius and double it to find the diameter.

Write the formula. Volume=π⋅radius2⋅height.

Substitute the dimensions of the shape into the formula. Use 3.14 as the value for π. 791.28=3.14⋅r2⋅28.

Solve the equation for the variable.
