Two years ago, Sally had 5,000 dogs in her dog shelter. Now she has 24,575 dogs. The rate of change is 391.5 % increase
<em><u>Solution:</u></em>
Given that Two years ago, Sally had 5,000 dogs in her dog shelter
Now she has 24,575 dogs
To find: rate of change
A rate of change is a rate that describes how one quantity changes in relation to another quantity
<h3><u>Steps to follow:</u></h3>
- First: work out the difference (increase) between the two numbers you are comparing.
- Increase = New Number - Original Number.
- Then: divide the increase by the original number and multiply the answer by 100.
- % change = Increase ÷ Original Number x 100
Thus the rate of change is 391.5 % increase
10 - 6x = 160 - 10x
+6x +6x
-10 + 6 = -4
10 = 160 - 4x
-160
10 - 160 = -150
-4x = -150
-4x/4 = -150/-4
x= 37.5
Answer:
D. 24 strawberries
Step-by-step explanation:
Density = mass / volume
Givens
Density = 13.6 grams / cm^3
mass = 47 grams.
Solve
D = m/v
13.6 = 47 / volume Multiply by volume
13.6 * volume = 47 Divide by 13.6
volume = 47 / 13.6
Volume = 3.46 ccs
Answer:
Step-by-step explanation:
4) A photograph costs $20, so the cost of x photographs is 20x.
Similarly, the cost of y prints is $25.
So the total cost is 20x+25y, and this has to be less than or equal to 400, so C.
5) just plug each pair in.
For example for the first option, x=5 and y=10, and since 20(5)+25(10)=100+250. which is less than or equal to 400, it works.
