Jeff was already 7 miles out of town when his sister
Nikolay [14]

The sister catches up Jeff after 2 hours

Step-by-step explanation:

We can write Jeff's position and his sister position at time t using the following expressions:

- Jeff position:

x_j(t) = 7 + 2.5 t

where:

7 is the initial position of Jeff when his sister sarts chasing him

2.5 is Jeff's velocity (in miles/hour), so its position increases by 2.5 miles for each hour

t is the time measured in hours

- Sister position:

x_s(t) = 6t

where

6 is the sister velocity (her position increases by 6 miles for every hour)

t is the time measured in hours

The sister catches up Jeff when the two positions are equal, so

x_j(t) = x_s(t)\\7+2.5t=6t

And solving for t,

7+2.5t-2.5t=6t-2.5t\\7=3.5t\\t=\frac{7}{3.5}=2 h

So, the sister catches Jeff after 2 hours.

Natalie had 64 beads. She used 24 beads to make a bracelet. She used 7/8 of the remaining beads to make a necklace. How many bea
Eddi Din [679]

Answer:

Natalie have left with 5 beads.

Step-by-step explanation:

Given:

Natalie had 64 beads. She used 24 beads to make a bracelet. She used 7/8 of the remaining beads to make a necklace.

Now, to find the beads does Natalie have left.

<em>Total beads Natalie had = 64 beads.</em>

<em>And beads she used to make a bracelet = 24 beads</em>.

So, the remaining beads are = 64-24=40\ beads.

Now,<em> the beads she used to make a necklace</em> = 40 of \frac{7}{8}

                                                                             = 40\times \frac{7}{8}

                                                                             = \frac{280}{8}

                                                                             = 35\ beads  

Hence, the beads Natalie have left = remaining beads - beads used to make necklace.

The\ beads\ Natalie\ have\ left\ =\ 40-35

The\ beads\ Natalie\ have\ left\ =\ 5\ beads.

Therefore, Natalie have left with 5 beads.
