The cost of 4 erasers is $5.88.

Step-by-step explanation:

The graph represents the speed at which Pete’s marble travels.
AfilCa [17]

Answer:

B

Step-by-step explanation:

Here, we simply want to know who will reach the 6-foot mark sooner

Mathematically, we need to get the slope from the graph

Looking at the graph, we can see that the 3 ft mark was reached at exactly 2 seconds

So what this mean is that, in 4 seconds, the 6 ft mark will be reached

This makes up the fact that the speed for Pete’s travel is 1.5 ft/ secs

Now compare this with what Stephano has, which is 2.25 ft/ s

we can see that stephano is traveling at a better speed and will reach the 6 ft mark first

So the correct option is B

Question 11 the length of a rectangle is six times its width. if the perimeter of the rectangle is 98 m , find its area.
andrezito [222]
Let's look at the formula to solve the perimeter.
2l+2w=98
We know that l=6w
Let's put that into the equation.
2(6w)+2w=98
12w+2w=98
14w=98
98÷14=7
So the width is 7. Let's find the length.
Since the length is six times the width: 7×6= 42
So, the length is 42 while the width is 7. We need to find the area.
42×7=294
The area is 294 m².

Write an expression that represents the difference of t and 8
alisha [4.7K]
Hey there!

Here is your answer:

<u><em>The proper answer to this question will be "t-(8)".</em></u>

Reason:

<u><em>Look at the way the question is worded the word "difference" will mean its subtraction, and t would go first since its in the question and it goes first: t-8=! T representing the variable so you can add ( around the 8 so...  t - (8)=.....</em></u>

<em>Therefore the expression should be t - ( 8 ) =</em>

If you need anymore help feel free to ask me!

Hope this helps!
