Answer:
If you take the rectangle with the geometric center O. Match the sides of opposite triangles. AB will be equal to CD and AC is equal to BD. Angles AOB is equal to the angle COD and angle AOC is equal to angle BOD.
The two diagonals bisect each other and therefore each all parts of the diagonal are equal.
Therefore the two diagonals are congruent.
0.5x + 25 is your equation, since 25 is just a one time thing.
Answer:
$115
Step-by-step explanation:
Although it did say to complete the equation I put the answer just in case.
So, in order to calculate the total weekly income, I will use x which will equal the number of hours. The equation needed to calculate the weekly total income will be:
w = 6x + 25
Because we know the number of hours is 15, we can plug 15 in x:
w = 6(15) + 25
w=90+25
w=115
So, the total weekly income will be $115(don't forget to put the unit! In this case it will be the dollar sign).
Answer:
c
Step by step explanation: Linear equations don't have exponents, so that makes option c nonlinear
Answer:the mass of the air inside the inflated balloon is 4 grams
Step-by-step explanation:
The initial mass of the balloon before it was inflated by the Math and Science class is 4 grams. After the balloon was inflated, the mass was 8 grams. This means that the mass by which the balloon increased would be the mass of the inflated balloon - the initial mass of the balloon. It becomes
8 - 4 = 4 grams.
Therefore, the mass of the air inside the inflated balloon is 4 grams.
