Answer:

150 seconds

Step-by-step explanation:

use the velocity equation of

V=\frac{delta(D)}{Delta(T)\\}

Where V is in feet per second, Delta D represents the change in displacement and delta t represents the change in time

all you need to do is rearrange the equation to find Delta(T)

as such...

Delta(t)*V=Delta(D)\\Delta (t)=\frac{Delta(D)}{V}\\Then\ insert\ your\ corresponding\ values\\\Delta(t)=\frac{270 ft}{1.8 feet/sec}  \\Delta (t)= 150sec

Gerain and Deon are making trail mix. Gerain's recipe calls for 3 parts raisins to 2 parts almonds. Dean's recipe calls for 4 pa
Inessa [10]

To figure out which part has the higher concentration of almonds, we want to see how many almonds are there for every part in each recipe. For the first recpe, we have 2 parts almond for ever 5 total parts, and in the second part, we have 3 parts almonds for every 7 total parts, so we can represent them as the fractions:

\text{Gerain's concentration}: \frac{2}{5}\\ \text{Deon's concentration}: \frac{3}{7}

So, which one is greater? Well, let's say they both make 35 total batches (36 is the least commun multiple of the two denominators) that would give them:

\frac{2}{5}*35=2*7=14\text{ parts raisins}\\
\frac{3}{7}*35=3*5=15 \text{ parts raisins}

So we have Deon's recipe as the large concentration of raisins.

gladu [14]

Answer:

The independent variable is the dose of the drug given to each participant.

Step-by-step explanation:

In the current experiment each patient's initial level of pain is going to be the <em>initial condition </em>for the experiment. We're going to measure the final level of pain and we'll try to find any correlation between the variation in the level of pain and the number of milligrams of the drug given to each patient, so that last one (the dose of the drug) is the independent variable because is the one variable that we're going to modify in order to see the effect that it has in the final measurement.
