Answer:
1/4
Step-by-step explanation:
1/4 x 2 = 1/2
1/2 divided by 2 is 1/4
The answer is <span>C.) 2
The general form of formula is
y = a </span><span>• r^x
y - the total number of bacteria after x period of time
a - the initial number of bacteria
r - growth rate
x - period of time
Let's compare:
</span>y = a • r^x
<span>y = 280 • 2^x
Since r = 2, the growth rate is C.) 2</span>
Answer:
11.)
We can let the scores we don't know by x, and we know that tokay had 14 more points than Lodi. This can be shown as the following:
x + (x+14) = 162
2x+14=162
162-14= 148
148/2 = 74
Therefore Lodi scored 74 points.
12.)
We can substitute the prices we don't know by x and have the following:
4x+x=6.50
5x=6.50
6.50/5= 1.3
4x1.3= 5.2
Therefore the sandwich cost $5.20 and the drink costs $1.30
The scale of the map from inches to miles is 1 inch : 9 miles
<h3>How to determine the scale of the map from inches to miles?</h3>
The given parameters are:
- The actual distance of the cities apart = 36 miles
- The scale distance of the cities apart = 4 inches
The scale of the map from inches to miles is represented as:
Scale of map = The scale distance of the cities apart : The scale distance of the cities apart
Substitute the known values in the above equation
Scale of map = 4 inches : 36 miles
Divide both sides of the ratio by 4
So, we have:
Scale of map = 4/4 inches : 36/4 miles
Evaluate the quotient
Scale of map = 4/4 inches : 9 miles
Evaluate the quotient
Scale of map = 1 inch : 9 miles
Hence, the scale of the map from inches to miles is 1 inch : 9 miles
