The length of a rectangle is 4 centimeters less than twice its width. The perimeter of the rectangle is 34 cm. What are the dime
yarga [219]

Let l and w be the length and width of the rectangle. We know that l=2w-4

The formula for the perimeter is P=2(w+l)

Using our substitution, it becomes

P=2(w+2w-4)=2(3w-4)=6w-8

We know that the perimeter is 34, so we have

6w-8=34 \iff 6w=42 \iff w=7

The length is 4 less than twice the width, so we have

l=2\cdot 7 - 4 = 10

Can someone help me with this plzz
topjm [15]

Answer:

14

Step-by-step explanation:

We can see that the spinner is spun 50 times if we add all the "times spun" up.

7 + 8 + 7 + 8 + 11 + 9 = 50

So if we multiply this by 2, we should get the theoretical probability that 1 will be spun if the spinner was spun 100 times.

1 was spun 7 times when we spun the spinner 50 times, so we can predict that 1 will be spun 14 times if we spin the spinner 100 times.

I appreciate all the help guys! Need help on this one y’all
lisov135 [29]
You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.

90/60 = 1.5

90 minutes = 1.5 hours

speed = distance/time = (105 miles)/(1.5 hours) = 70 mph
