Find the measure of each angle indicated.

A) 21°
C) 23
E) 25°
B) 80°
D) 20°

Answers

Answer:

D) 20⁰

Step-by-step explanation:

EDF = 180-100=80⁰

EFD= 80⁰+80⁰=160⁰

180⁰-160⁰=20⁰

Answer:

I would say D, 20°

Step-by-step explanation:

angles on a straight line should be equal to 180°. so 180 -100 = 80° inside.

angles inside a triangle should also be 180. So, 80° + 80° =160°. to get the other angle subtract 160 from 180 to get 20°

In an unknown planet, a rock with a mass of 10 kg has a weight of 20 N. What is the gravitational acceleration of objects near the surface of the unknown planet?​

Answers

Answer:

The gravitational force between a mass and the Earth is the object’s weight. Mass is considered a measure of an object’s inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg. Kilograms and slugs are units of mass; newtons and pounds are units of weight.

You can use Newton’s law of gravitation to get the acceleration due to gravity, g, on the surface of the Earth just by knowing the gravitational constant G, the radius of the Earth, and the mass of the Earth. The force on an object of mass m1 near the surface of the Earth is

F = m1g

This force is provided by gravity between the object and the Earth, according to Newton’s gravity formula, and so you can write

Answers

Answer: x = 7

Step-by-step explanation:

5x + 7 = 42

We then take 7 away from both sides:

5x = 35

Then, we need to make it so x = answer. To make 5x into x, we divide by 5 meaning that we next need to divide both sides by 5.

x = 7

A box of chocolates contains bars of milk chocolate and dark chocolate. The weight of each bar of milk chocolate and dark chocolate is 150 ounces and 100 ounces respectively. If the number of bars of dark chocolate is 12 more than the number of bars of milk chocolate, and the total weight of the chocolates in the box is 2950 ounces, find the number of bars of milk and dark chocolate.

Answers

Answer:

7 milk chocolate

19 dark chocolate

Step-by-step explanation:

It is 2950 ounces in total, and dark chocolate is 100 ounces per bar and milk chocolate is 150 ounces per bar. There are 12 more dark chocolate bars so I multiplied 12 by 100 and that was 1,200. Then I took 2,950-1200=1,750. From there I subtracted 150 and 100 till I got to 0.

Number of bars of milk chocolate: 17

Number of bars of dark chocolate: 29

Let's use algebraic equations to solve the problem. Let's denote the number of bars of milk chocolate as "x" and the number of bars of dark chocolate as "y."

1. Weight equation: The total weight of the chocolates in the box is 2950 ounces.

We can express this as an equation:

150x + 100y = 2950  

2. Quantity equation: The number of bars of dark chocolate is 12 more than the number of bars of milk chocolate.

We can express this relationship as:

y = x + 12

Now, we have a system of two equations with two variables:

Equation 1 : 150x + 100y = 2950

Equation 2 : y = x + 12

To find the values of x and y, we can use substitution or elimination. Let's use substitution in this case.

From Equation 2, we can substitute the value of "y" in terms of "x" into Equation 1:

150x + 100(x + 12) = 2950

Now, we can solve for "x":

250x + 1200 = 2950

250x = 1750

x = 7

Now that we have the value of "x," we can find the value of "y" using Equation 2:

y = x + 12

y = 7 + 12

y = 19

So, the number of bars of milk chocolate (x) is 7, and the number of bars of dark chocolate (y) is 19.

Equation of a Line in Slope-Intercept FormThe equation of a line can be represented in slope-intercept form as: y = mx + b."b" is the y-intercept.

Given:

2x + 5y = -6

Rewrite in slope-intercept form

5y = -2x - 6

Divide both sides by 5

y = -2/5x - 6/5

Answer:

-155.15

-223.75

Step-by-step explanation:

Transaction 1 was a deposit of 360. The account had nothing in it before that deposit. After the 360 deposit the balance is 360.

Transaction 2 is -22.50. That means 22.50 was withdrawn (taken out) from the account. The balance after transaction 2 is 360 - 22.50 = 337.50.

Before transaction 3 takes place, the balance is 337.50.

After transaction 3 takes place, the balance is lower. It is now 182.35.

The amount of money taken out in transaction 3 is 337.50 - 182.35 = 155.15. Transaction 3 is -155.15.

The balance after transaction 3 is 182.35. The balance after transaction 4 is -41.40 which is lower than 182.35, so transaction 4 is again withdrawing money from the account.

The amount of transaction 4 is:

182.35 - (-41.40) = 223.75

Transaction 4 is: -223.75

Is it equivalent or is it not equivalent pick one

Answers

Answer:

Step-by-step explanation:

−(−12−6x−3)

= 12 + 6x + 3

= 6x + 15.

So 3.5 − 6x  is not equivalent to −(−12−6x−3)

Both linear equations are not equivalent to each other and this can be determined by evaluating the equation (-(-12 - 6x - 3)) by using the arithmetic operations.

Given :

Equations  ---  -(-12 - 6x - 3) and (3.5 - 6x)

The following steps can be used in order to determine the given equations are equivalent or not:

Step 1 - Write the given equations.

=−(−12−6x−3)               ---- (1)

= (3.5 − 6x)                  ---- (2)

Step 2 - Multiply -1 by (−12−6x−3) in the equation (1).

= 12 + 6x + 3

Step 3 - Add 12 and 3 in the above expression.

= 6x + 15   ---- (3)

Step 4 - Now, compare equation (2) and equation (3).

6x + 15 [tex]\neq[/tex] 3.5 - 6x

So, from the above steps, it can be concluded that both linear equations are not equivalent to each other.
