Answer:

2 second

Step-by-step explanation:

divide 200/150-2

Answer:

-2

Step-by-step explanation: theres no image so i cant tell for sure but if it is rotating counterclockwise then that means its negative.

The coordinates of the image of point Y after these transformations is -2. The figure given has been translated up two units and turned 180 degrees counterclockwise.

The Cartesian coordinate plane is an endless two-dimensional plane. On an endless 2d plane, any two-dimensional figure may be drawn. A location is assigned to each point in a Cartesian plane.

The figure given has been translated up two units and turned 180 degrees counterclockwise.

After these changes, the coordinates of the image of point Y are -2.

Hence, the coordinates of the image of point Y after t, These  transformations is -2.

Answer:

Step-by-step explanation:

q+n=25

n=25-q

25q+5n=505, using n=25-q in this equation gives you

25q+5(25-q)=505

25q+125-5q=505

20q+125=505

20q=380

q=19

So 19 of the coins are quarters.

A translation moves every point of a figure or a space by the same amount in a given direction. The reflection of a red shape against an axis followed by a reflection of the resulting green shape against a second axis parallel to the first one results in a total motion which is a translation of the red shape to the position of the blue shape.

Actually Welcome to the Concept of the Parallel lines and Transvell.

We here are going to use the concept of Corresponding angles, co- interior angles and linear pair also Adjacent angles.

hence, we get as,

1.) x = 60° , y = 60°.....(vertically opposite angles)

2.) x = 120° , y = 120°

3.) x = 105° , y = 75°

4.) x = 140° and y = 40°

All are above done.

Step-by-step explanation:

I know this might not be a great answer, but for myself it is much easier to remember math concepts when I apply the concept to real world problems while I am learning. This has two benefits, you will be practicing the concept which reenforces the learning and it automatically tells your brain that the information is valuable in life and that is should remember the idea.

Answer:

8:1

Step-by-step explanation:

Okay so the ratio from cocoa to sugar from the chart is 8:2. To simplify this you could multiply both sides by 2 which would get you 4:1 or 4. Now the question asks what is the ratio Leah will use when this is doubled. In order to do this you can multiply 4 by 2 which gets you 8. Or 8:1. Hope you understand :)

Answer:

-1,050

Step-by-step explanation: This is quite simple first we know that 2,100 is negative(-2,100) because it is descending/going down. So now we know that we can divide -2,100 by 2 which sums up to 1,050. But we are going to have to add a negative sign due to the fact that if the two integers you are dividing are opposite signs it would be negative. So if you add a negative sign to 1,050 it would be -1,050. Just to keep in mind that opposites make negative when dividing I will put the integer rules below.

Answer:

The answer is -1,050.

Step-by-step explanation:

An equation to represent the relationship between the submarines elevation & time would be y=-1,050x. Since we know that in two hours the submarine can reach 2,100 feet below the surface we need to figure out how long the submarine can reach in 1 hour. So we do 2,100/2 which equals 1,050. And since the submarine going below, it turns into -1,050.

Answer:

y = 3/2x + 5/2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let's solve your system by substitution.

5x+3y=35;2x+4y=28

Step: Solve 5x+3y=35 for x:

5x+3y=35

5x+3y+−3y=35+−3y(Add -3y to both sides)

5x=−3y+35

5x/ 5 = −3y+35/ 5  (Divide both sides by 5)

Step: Substitute  −3/ 5 y+7 for x in 2x+4y=28:

2x+4y=28

2( −3/ 5 y+7)+4y=28

14/ 5 y+14=28   (Simplify both sides of the equation)

14/ 5 y+14+−14=28+−14   (Add -14 to both sides)

14/ 5 y=14

14/ 5 y/ 14/ 5 = 14/ 14/ 5

(Divide both sides by 14/5)

y=5

Step: Substitute 5 for y in x= −3/ 5 y+7:

x= −3/ 5 y+7

x= −3/ 5 (5)+7

x=4  (Simplify both sides of the equation)

Answer:

x=4 and y=5
