Answer:7.956

Have a good day

Step-by-step explanation:

Answer:

7.956

Step-by-step explanation:

10.2*0.78 can be rewritten as 102*78*0.001. I'd split this even further, since I'm doing it in my head, into (100*78+2*78)*0.001. One step at a time.

100*78=7800

2*78=140+16=156

7800+156=7856+100=7956

7956*0.001=7.956, which is the answer, and is confirmed by a calculator

I will give brainiest How does the function y = -2x + 6 differ from the linear parent function?

Answers

So the parent function is y=x, right? y=-2x+6 is different because the slope is -2 (which flips the line so it's now going from left to right while also being more "taller", and the line's y-intercept is 6, while on the parent function, the y-intercept is 0.

Parent function: y = x (or y=mx+b)

Your function: y = -2x+6

6 = y-intercept (b)

-2 = slope (m)

Which of these sequences of transformations would not return a shape to its original position?

Group of answer choices

1. Translate 3 units up, then 3 units down.

2. Reflect over line p, then reflect over line p again.

3. Translate 1 unit to the right, then 4 units to the left, then 3 units to the right.

4. Rotate 120∘ counterclockwise around center C, then rotate 220∘ counterclockwise around C again.

Answers

Answer:

4. Rotate 120∘ counterclockwise around center C, then rotate 220∘ counterclockwise around C again.

Step-by-step explanation:

Option 1, 2 and 3 will return a shape back to its original because:

1. 3 units up and 3 units down are direct opposite and will cancel out one another. Hence, the shape will return to its initial position.

2. Reflect over line p, and over p again.

This actions are also direct opposite and also have the same effect as (1)

3. Translate 1 unit to the right and 3 units to the right.

This equates to 4 units to the right and it will cancel out the translation of 4 units to the left.

4. Rotate 120 counter clockwise and another 220 counterclockwise will not make a shape go back to its original position.

Hence:

the area of a circle is 36pi cm^2, what is the radius of the circle

Answers

Answer:

Step-by-step explanation:

So, to find the area of the circle you use the equation pi r^2, so we need to do this in reverse to find the radius, r.
So we can set up this equation:
36pi = pi r^2
So if we divide by pi on both sides we get
36 = r^2
Then we square root both sides:
6 = r
So the radius is 6cm

Triangles LNM and SRT are similar, so corresponding angles are congruent. In particular, angles M and T are congruent. The interior angles of any triangle sum to 180º in measure, so

65º + 55º + (2x + 30)º = 180º

Solve for x :

(2x)º + 30º = 60º

(2x)º = 30º

x = 15

If -2z+3=9 what is the value of 2/3z?

Please Explain the steps.

Answers

Answer:

-2

Step-by-step explanation:

1.Subtract 3 from both sides and the equation is -2z=6

2.Divide both sides by -2 and the equation is z=-3

3.Multiply -3 by 2/3 and you get -2

Answer:

2/3z = -2

Step-by-step explanation:

1. First you want to find out what z is, so you have to solve for z.

2. To solve for z, first subtract 3 from the 3 and the 9. 3 minus 3 is equal to 0, so it cancels out. 9 minus 3 is equal to 6.

3. The new equation is -2z = 6, so now you have to divide -2z by -2 and 6 by -2. -2z divided by -2 is equal to 1z or z, and 6 divided by -2 is equal to -3.

4. The simplified equation is z = -3.

5. Now that we solved for 1z, we have to solve for 1/3 by dividing 1 by 3 and -3 by 3. 1 divided by 3 is 1/3, and -3 divided by 3 is -1.

6. We have solved for 1/3z (1/3z = -1), but now we want to solve for 2/3z so we have to multiply 1/3z by 2, and -1 by 2. 1/3z times 2 is 2/3z, and -1 times 2 is equal to -2.

7. The simplified equation for the value of 2/3z in the equation -2z + 3 = 9 is 2/3z = -2
