What is the triangle for these measurements?
cestrela7 [59]

<u>Step-by-step explanation:</u>

If no sides of a triangle are congruent (equal) then it is SCALENE

If two sides of a triangle are congruent (equal) then it is ISCOSCELES

If all sides of a triangle are congruent (equal) then it is EQUILATERAL

90, 35, 55: no sides are congruent = SCALENE

700, 550, 550: two sides are congruent = ISCOSCELES

350, 400, 1000: no sides are congruent = SCALENE

460, 460, 440: two sides are congruent = ISCOSCELES

1200, 300, 300: two sides are congruent = ISCOSCELES

Mallory and Aimee save money for summer camp. They both plan to save the same amount of money. Mallory has 35$ and plans to save
Mrrafil [7]

Answer:

0.857 weeks

Step-by-step explanation:

Using the information provided we can create the following equations for the total amount Mallory (M) and Aimee (A) will save after x number of weeks...

M = 35 + 15x

A = 5 + 50x

Now we would need to make both of these equations equal one another and solve for x to calculate after how many week both Aimee and Mallory will have saved the same amount of money

35 + 15x = 5 + 50x  ... subtract 5 and 15x from both sides

30 = 35x  ... divide both sides by 35

\frac{30}{35} or 0.857 = x

Finally, we can see that after 0.857 weeks both Mallory and Aimee will have saved the same amount of money.

*** The process provided is correct but I believe that the actual values for Aimees savings should be $50 and plans to save $5 a week, this would make the final result 1.5 weeks which would make more sense***
