Answer:

12 times

Step-by-step explanation:

Earth-Moon (EM) = 12⁵ miles

Sun-Mercury (SM) = 12⁷ miles

Sun-Jupiter (SJ) = 12⁸ miles

just FYI, these numbers are only a rough simplification for this example. the real distance are quite a bit different.

so, SJ/SM = 12⁸ / 12⁷ = 12¹ = 12

=> Jupiter is 12 times farther away from the Sun than Mercury.

parallelogram ABCD is reflected over the y axis, followed by a reflection over the x axis, and then rotated 180 degrees about th

mixer [17]

Answer: Option c.

Step-by-step explanation:

The missing figure is attached.

Given a point $(x,y)$ :

1. If it is reflected over the y-axis:

$(x,y)$ → $(-x,y)$

2. If it is reflected over the x-axis:

$(x,y)$ → $(x,-y)$

3. If it is rotated 180 degrees about the origin:

$(x,y)$ → $(-x, -y)$

In this case, you can identify that the point A is:

$A(-5,1)$

Then:

If it is reflected over the y-axis:

$(-5,1)$ → $(5,1)$

If then it is reflected over the x-axis:

$(5,1)$ → $(5,-1)$

Finally, if this is followed by a rotationf of 180 degrees about the origin, this is:

$(5,-1)$ → $(-5,1)$

I need help because I'm solving these questions by the manual, and yet it still says that I am wrong after multiple attempts.

Alexxandr [17]

Answer:

1. QR = HI

2. angle W and angle T

3. WB = UV

Step-by-step explanation:

It could me fill in the part of the proof, since I notice on all of them they only mark one or two of the congruencies on the shapes. I'm not really sure of 3's answer.

Hope this helped somewhat and good luck

Suppose that y varies directly with x and y=10 when x=20. What is y when x=15

Likurg_2 [28]

Answer:

y=kx

subst y=10 and x=20 into the above

10=k20

k=10/20

k=1/2

therefore relationship: y=1/2x

subst x=15 into the relationship

y=1/2(15)

y=7,5

Step by step explanation:

Step 1: when they say y varies directly with x they mean y is proportional to x
step 2: so y=kx where k is the constant
step 3: is to substitute y=10 and x=20 into the above equation y=kx
step 4: you will end up with 10=k20 then divide both sides by 20 so that k becomes the subject of the formula 
step 5: your answer from the above will be k=10/20 so the relationship is y is directly proportional to 1/2 x what you did here is that you substituted k for 1/2 in the equation in step 3
step 6: is to finally substitute x=15 into the equation y=1/2x to finally get your answer y=7,5.
