* A turtle and a snail start moving towards each other when they are 200 feet apart. The turtle is running at a speed of T feet per minute, and the snail is moving at a speed of S feet per minute. How soon will they meet?

Answers

Answer:

        200 ft               200

t = -------------------- = ---------- min

      (S + T) ft/min      S + T

Step-by-step explanation:

Recall that distance = (rate)(time).

The distance traveled by the turtle in t minutes is dt = (T ft/min)(t), and

the distance traveled by the snail in t minutes is ds = (S ft/min)(t).  We know that ds + dt must be 200 ft.

Thus,

(S ft/min)(t) + (T ft/min)(t) = 200 ft.

The variable t, representing elapsed time, is common to both terms on the left.  Thus,

        200 ft               200

t = -------------------- = ---------- min

      (S + T) ft/min      S + T

Answer:

S+T

PLEASE HELP DUE IN 5 MIN!!!!!!!!!!!!!!!!!!! A study was designed to determine the relationship between the weight of new cars and their gas mileage. What are the independent and dependent variables for this study? A. The independent variable is the gas mileage, and the dependent variable is the weight of the cars. B. The independent variable is the gas mileage, and the dependent variable is the age of the cars. C. The independent variable is the weight of the cars, and the dependent variable is the age of the cars. D. The independent variable is the weight of the cars, and the dependent variable is the gas mileage.

Answers


If the weight of the car were the dependent variable, then
that would mean that the weight of the car depends on the
gas mileage.  In that case, the car would probably have
different weights in the city and on the open highway. 
The car would really get heavy when you drive it during
rush hour on a rainy day.  But if a trained professional
efficiency driver checked the tire pressure, tuned up the
\ignition system and the fuel mixture, then got in and took it
for a spin out on the highway on a cool sunny day, maintained
a constant speed, avoided sudden starts and stops, let the
car gain speed on the down-hills and let it lose speed on the
up-hills, then the car's weight would drop lower than it's ever
been before.
Does any of this sound reasonable to you ?

Which number sentence below is not correct? 24.154 < 24.15 23.07 < 23.072 24.67 = 24.6700 28.045 > 28.044

Answers

Answer:

Option 1 - 24.154 < 24.15

Step-by-step explanation:

To find : Which number sentence below is not correct?

Solution :

1) 24.154 < 24.15

It is false as 24.154 is 0.004 times greater than 24.15.

2) 23.07 < 23.072

It is true as 23.07 is less than 23.072.

3) 24.67 = 24.6700

It is true as zero after decimal doesn't make any change.

4) 28.045 > 28.044

It is true as 28.045 is greater than 28.044.

Therefore, Option 1 is correct.
24.154 <24.15 that is the incorrect  one
