What I understand from the picture given, she had 2 ribbons with the length of 1/4.
These would be the two shortest ones.
So: 1/4 + 1/4 = 2/4
= 1/2

I hope this helps and I know that it is different to what HimyBrainy put but it is what I understood! :/

Analysis of an accident scene indicates a car was traveling at a velocity of 69.5 mph (31.1 m/s) along the positive x-axis at th

STatiana [176]

We can find the acceleration via

${v_f}^2-{v_i}^2=2a\Delta x$

We have

$\left(5.20\dfrac{\rm m}{\rm s}\right)^2-\left(31.1\dfrac{\rm m}{\rm s}\right)^2=2a(115\,\mathrm m)$

$\implies\boxed{a=-4.09\dfrac{\rm m}{\mathrm s^2}}$

Then by definition of average acceleration,

$a_{\rm ave}=\dfrac{v_f-v_i}t$

so that

$-4.09\dfrac{\rm m}{\mathrm s^2}=\dfrac{5.20\frac{\rm m}{\rm s}-31.1\frac{\rm m}{\rm s}}t$

$\implies\boxed{t=6.33\,\mathrm s}$

We alternatively could have found the time without knowing the acceleration. Since acceleration is constant, the average velocity is

$v_{\rm ave}=\dfrac{x_f-x_i}t=\dfrac{v_f+v_i}2$

Then

$\dfrac{115\,\rm m}t=\dfrac{5.20\frac{\rm m}{\rm s}+31.1\frac{\rm m}{\rm s}}2$

$\implies\boxed{t=6.33\,\mathrm s}$

Find the sum of the sequence. 45+46+47+48+...+108

Anna11 [10]

We know, S = n/2 [ a + l ]
Here, a = 45
l = 108

Calculation of n:
a(n) = a + (n - 1)d
108 = 45 + (n - 1)1
108 - 45 = n - 1
63 + 1 = n
n = 64

Now, substitute in the expression:
S = 64/2 [ 45 + 108 ]
S = 32 [ 153 ]
S = 4896

In short, Your Answer would be 4896

Hope this helps!

Solve each inequality below. Represent the solutions on number lines. 7x − 2 < 3 + 2x

LekaFEV [45]

Hi, I would be glad to help you here.

<span>7x − 2 < 3 + 2x

Move terms

7x - 2x - 2 < 3

Collect the like terms

(7x - 2x) = 5x (<3 + 2 stays the same)

Calculate

5x (<3 + 2 = 5)

5x <5

Divide both sides of the inequality by (5) giving you,

x < 1

So, finally in a total the correct answer here is (x < 1)
