Simple...
you have: C(X)=3x+2.00
x=number of minutes
Pay attention to the y=mx+b form where m=slope-->>
3x is the slope...
so it's 3(times the number of minutes) <<---or (x)
This means that the slope is 3, or the fancy way of saying it-->>"rate of change."
The rate of change of the cost of the taxi ride is $3.00 per minute.
Thus, your answer.
To answer this question you should begin with the coin that has a higher value. If you start with the dime and then just add the correct number of pennies to total $0.40, you will see that you will need 3 dimes ($0.30) and 10 pennies ($0.10).
I used a guess and check strategy starting with 2 dimes.
To find out which cake is better for the price, we need to multiply the cake amounts by how many cakes of that kind we need. You need 5 20cm cakes, so we multiply 5 by the price of the 20cm cake (13.50) to get $67.50. You need 3 25cm cakes, so 3 x 18.75 = 56.25.
20cm cake: $67.50
25cm cake: $56.25
Answer: The 25cm cake is cheaper for more people.
Answer:
Option C.LG≅TD
Step-by-step explanation:
we know that
If two figures are congruent, then its corresponding sides and its corresponding angles are congruent
In this problem
MTD≅SLG
so
<em>Corresponding sides</em>
MT≅SL
TD≅LG
MD≅SG
<em>Corresponding angles</em>
∠M≅∠S
∠T≅∠L
∠D≅∠G
