How do you know if a transfomation is rotation translation or reflection​
aksik [14]

Answer:

Step-by-step explanation:

Translation: You move the shape by moving the points on the shape by the number, it changes the location of the shape.

Reflection: There is a line of reflection and the shape will be reflected by that, like a mirror, so it will be the same shape, same size.

Rotation: There is a point of rotation and the shape will just move around that point and will change the positioning if the shape. Always has coordinates

Jug A has 0.1 litres more than jug B. Jug C has 200 millilitres less than jug B. Jug D has ¼ of the amount that is in jug A. The
Gnesinka [82]

Answer:

A = 0.8 litres

B = 0.7 litres

C = 0.5 litres

D = 0.2 litres

Step-by-step explanation

Here's what we know:

1. Jug A = B + .1 litres

2. Jug C = B - 200 (or 0.2 litres)

3. Jug D = .25 x A

4. Jug A + Jug B = 1.5 litres

In problem 1, we learned that Jug A has .1 litres more than Jug B and in problem 4, the two of them added together are 1.5 litres. To solve this we can combine the problems.  

B + .1 litres + B = 1.5 litres

2B + .1 = 1.5

Subtract .01 from each side and you have 2B = 1.4

Divide each side by 2 and you have B = 0.7 litres

Plug this info into problem 1 and you can solve for A. (0.7 + 0.1 = 0.8)

Plug this info into problem 2 and you can solve for C. (0.7 - 0.2 = 0.5)

Since you have A, you can use that info to solve problem 3 (0.25 x 0.8 = 0.2)

If AD = 5x - 7 and AB = 2x +11, what is the length of AD
Norma-Jean [14]

Answer:

The length of AD is 6.

Step-by-step explanation:

Solve.

5x - 7 = 2x + 11 \\  \frac{ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  - 2x \:  \:  \:  \:  \:  \:  =  - 2x \:  \:    \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  }{3x - 7 = 11}  \\  \frac{  \:  \:  \:  \:  \:  \:  \:  \:  \:  + 7  =  + 7}{3x = 18}  \\  \\  \frac{3x}{3}  =  \frac{18}{3}   \\  \\ x = 6

Now plug in:

5x - 7 \\ 5(6) - 7 \\ 30 - 7 \\ 23

^Therefore, your result^
