Answer:

D- A translation 2 units down followed by a 270-degree counterclockwise rotation about the origin.

Step-by-step explanation:

I'm sorry that it's late, I still posted it tho so you can give other person branliest.

Hope this helps for other readers :)

Explanation:

If you focus on one point, I'm doing R

if you first translate it down you will go from (3,4) to (3,2)

Then we have R' at (2, -3) which means we need (y, -x)

This can be found with 90 degree clockwise OR 270 degree counterclockwise.

Jessica has two strings. The first string measures 80 centimeters and the second string measures 64 centimeters.She wants to cut

finlep [7]

Answer: 16 inches.

Step-by-step explanation:

given data:

length of string A = 80 centimeters.

length of string B = 64 centimeters.

step 1

we solve for the Highest common denominator between them.

highest common denominator = 16.

what this represents is that no string would be cut more than 16inches so they can all have equal lengths at the end of cutting.

Write an inequality to match each description. Use n for the variable.

mel-nik [20]

${\huge {\mathfrak {Answer :-}}}$

Let, the length be l and breadth be b.

So, 2(l + b) = 26

Or, l + b = 13

Or, l = 13 - b

So, we may write like this,

Area = l * b

Or, l * b > 30

Or, l (13 - l) > 30

Or, 13l - l^2 > 30

Or, l^2 - 13l + 30 > 0

Or, l^2 - 3l - 10l + 30 > 0

Or, l(l - 3) - 10(l - 3) > 0

Or, (l - 3)(l - 7) > 0

Or, l - 7 > 0

Or, l > 7.

Now, putting the value of l,

We get, l * b > 30

Or, 7 * b > 30

Or, b > 30/7

➡️ Therefore, we get,

Length > 7

Breadth > 30/7

That's it..

6. Michael Johnson holds the Olympic record for the men's 400m race at 43 seconds. His

vlada-n [284]

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second

Step-by-step explanation:

We have to calculate his unit rate for both type of races

So,

Unit rate for 400m race:

Distance = 400m

Time = 43 sec

$Unit\ rate = U_1= \frac{Distance}{Time}\\=\frac{400}{43}\\=9.30\ meters\ per\ second$

Unit rate for 300m Race:

Distance = 300m

Time = 31 sec

$Unit\ Rate= U_2=\frac{300}{31}\\=9.68\ meters\ per\ second$

The difference between both unit rates is:

$U_2-U_1 = 9.68-9.30\\=0.38 => 0.4\ meters\ per\ sec$

Hence,

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second

40x + 60 = 20. what does x equal?

Elena-2011 [213]

Subtract 60 on both sides to get -40.

You are left with 40x=-40

Divide both sides by 40 to leave x by itself.

You get x=-1.
