Answer:
<em>Project 4 Score ; 41</em>
Step-by-step explanation:
Assuming that Project 4's score is x;
( Project 1 + Project 2 + Project 3 + Project 4 ) / 4 ⇒ take to substituting the value of each Project, provided Project 4's score being x;
45 = 42 + 49 + 48 + x / 4 ⇒ combine like terms,
45 = ( 139 + x ) / 4 ⇒ let 4 be a common denominator among numerator terms,
45 = 139 / 4 + x / 4 ⇒ divide 139 over 4,
45 = 34.75 + x / 4 ⇒ subtract 34.75 from either side,
10.25 = x / 4 ⇒ Multiply either side by 4,
x = 41 = Score of Project 4,
<em>Solution; Project 4 ⇒ 41</em>
The preimage is the solid triangle while the image is the dashed triangle. Recall that any transformation takes a preimage and maps it to an image. The "preimage" is the "before"; while the "image" is the "after"
Preimage ---> Image
Before ---> After
The "pre" is one way to help remember it means "before".
-------------------------
The preimage has a horizontal segment length of 15 units (count from x=-9 to x=6 and you should count out 15 spaces). The corresponding horizontal piece on the dashed triangle is only 3 units long. Divide the image length over the preimage length
(image length)/(preimage length) = 3/15 = 1/5 = 0.2
Now if the figure wasn't reflected over the point (6,6), then the final answer would be either 1/5 or 0.2; however, this reflection does happen so we need to make the scale factor negative. So we go from 1/5 to -1/5, and we go from 0.2 to -0.2
---------------------------------------------
Final Answer as a fraction: -1/5
Final Answer in decimal form: -0.2
The question can't be answered with the information given.
First of all, we don't know how fast the rain is falling ... how many inches
per hour.
But even of we knew that, that would only tell us how much water would
pile up in our yard or on our street. You're talking about a river, and
that's a whole different ball game.
The rain that falls right here is going to flow down the river to somewhere
else. But the rain that falls up-river from us is going to flow down to where
we are, and the river is going to rise. The amount it rises depends on . . .
-- how fast the rain is falling,
-- how much area it's falling on,
-- how much forest there is in that area and how many houses and
parking lots where the ground can't soak up the water and hold it,
-- and also on how wide the river is and how fast the water can flow through it.
