A plane flew 1,000 miles away from London for one flight. For the next flight, it flew 500 miles toward London. How far was the plane from London after the second flight?

Answers

So, It First Flew 1000 Miles Away. So, It Is Positive 1000 Miles. Now, It Flew 500 Miles Closer, So Negative (closer) Distance. So, Add. 1000+(-500)
Adding Negative Is The Same As Subtracting So, 1000-500 = The Distance.
So, The Distance Away Is 500 Miles. 

Answer:

500 miles

at memorial hospital 9 of the 12 babies born on Tuesday were boys In simplest form What fraction of the babies born on Tuesday were boys

Answers

9/12 = (9/3) / (12/3)= 3/4.

3/4 of the babies born on Tuesday were boys~

Answer:

Fraction =(3)/(4)

Step-by-step explanation:

Given : At memorial hospital 9 of the 12 babies born on Tuesday were boys

To find : What fraction of the babies born on Tuesday were boys

Solution : As we know total number of babies born in memorial hospital = 12

Out of 12 babies number of boys born on Tuesday = 9

So the fraction of babies born on Tuesday were boys

=\frac{\text{Number of boys}}{{\text{total number of babies}}}

=(9)/(12)

=(3)/(4)

Therefore, The fraction or simplest form of fraction =(3)/(4)

Please help! Triangle ABC is translated by the rule (x + 1, y + 1) and then dilated by a scale factor of 2 centered at the origin. Which statement describes the properties of triangles ABC and A''B''C'' after the transformations?A) ∠C and ∠C'' are congruent after both the translation and the dilation.
B) ∠C and ∠C'' are congruent after the dilation, but not after the translation.
C) segment AC and segment A double prime C double prime are congruent after both the translation and the dilation.
D) segment AC and segment A double prime C double prime are congruent after the dilation, but not after the translation.

Answers

Answer:

A

Step-by-step explanation:

1) Translated figures are congruent ones, so \bigtriangleup ABC\cong \bigtriangleup A'B'C', one unit to the right and one up in comparison to \bigtriangleup ABC\cong \bigtriangleup ABC.

2)Since \bigtriangleup A''B''C''  was dilated with a scale factor of two then It's a similar figure to  \bigtriangleup ABC. Similar figures have congruent angles and different sizes.

Hence, ∠C≅∠C"
