Answer: 3 min

Step-by-step explanation:

Step 1. Find the constant speed

you walked 1000 feet in 15 min

1000 ft/ 15min=200/3 ft / min

Step 2. Apply the constant speed to the left distance

You already walked 1000 feet and it is total 1200 feet

1200-1000=200 feet left

distance ÷ speed=time

200 ÷ (200/3)=3 min

Hope this helps!! :)

Please let me know if you have any question

If H= 2f over m+1, solve the equation for f
Viefleur [7K]
H = 2f / (m+1)
[multiply by (m+1)]
h(m+1) = 2f
[divide by 2]
f = (h (m + 1)) / 2

3b / (b+2) = 12 / (b+2)
[multiply by (b+2)]
3b = 12
[divide by 3]
b = 4

3 / (6x + 1) / 2 = 8 / (x + 4) / 3
[multiply both denominators to mike one denominator]
3 / 8(6x+1) = 8 / 3(x+4)
[expand brackets]
3 / (48x + 8) = 8 / (3x + 12)
[multiply by (48x + 8)]
3 = 8(48x + 8) / (3x+12)
[multiply by (3x+12)]
3(3x +12) = 4(48x + 8)
[simplify]
9x + 36 = 192x + 32
173x = 4
x = 4 / 173

Marcella Heinz purchased office supplies at Office Emporium for $107.64. She then purchased an English-Spanish dictionary for $1
Sliva [168]

The total amount of tax on her purchases to the nearest cent will be $9.97

<em><u>Explanation</u></em>

Marcella Heinz purchased office supplies for $107.64 and then she purchased an English-Spanish dictionary for $16.95

So, the total amount of her purchases =\$107.64+\$16.95=\$ 124.59

On the total amount of the purchases, she paid state sales tax of 7.5% and the county tax of 0.5%

So, the <u>amount of the state sales tax</u> =\$124.59*7.5\%= \$124.59*0.075=\$9.34425

and the <u>amount of county tax</u> =\$124.59*0.5\% =\$124.59*0.005 = \$0.62295

Thus, the total amount of tax on her purchases =\$9.34425+\$0.62295= \$9.9672 \approx 9.97  <em>(Rounded to the nearest cent)</em>
