For number 18 you would first want to convert all the measurements so you can determine who walked the furthest.....In this case we will convert the feet's and inches to yards because yards are longer..

Janelle - 429ft. 8in = about 143 yards
Lydia- 460 ft = about 153 yards

in this case I believe Lydia walked the farthest...

in all, how many counting numbers from 200 to 500 are divisible by all of the following 2, 3, 4,5 and 6?
Arte-miy333 [17]

Answer:

I think its  6 numbers  . See below

Step-by-step explanation:

The numbers must end in 0 because they must be divisible by 2 and 5

240 is one number it is the first number between 200 and 500 which is divisible by the 5 numbers.

The LCM of the 5 numbers is  60 so we can add  300, 360, 420 and 480 to the list.

vampirchik [111]

Answer:

Approximate percent error = 15%

Step-by-Step Explanation:

Let the percentage of error be "e"

Anticipated sales = 2,500

Actual sales = 2,125

The percentage error "e" can be calculated as per the equation below:

2500*(1-e) = 2125

(1-e) = 2125/2500

1-e = 0.85

e = 1-0.85

e = 0.15

e = 15%

Approximate percentage error = 15%

I have $225.00 in my account. I can spend al but 20% of that on some new equipment. What is the most that I can afford to spend
Setler79 [48]
You can "spend all but 20%" so that means you can spend up to 80% of your money (since 20%+80% = 100%). Apply 80% to the value 225

80% of 225 = (80/100)*225 = 0.80*225 = 180

The most you can afford to spend is $180

Solve 5x/3 + 2/5 = 1<br> x = 9/25<br> x= 25/9<br> x= 3/25<br> x = 9/27
musickatia [10]

Answer:

x=\frac{9}{25}

x = 0.36

Step-by-step explanation:

5x/3 + 2/5 = 1

5x/3 + 2/5 - 2/5 = 1 - 2/5

\frac{5x}{3}  = 0.6

5x/3 × 3 = 0.6 × 3

5x = 1.8

5x ÷ 5 = 1.8 ÷ 5

x=\frac{9}{25}

x = 0.36
