Answer: Time it took her to get to the school is 0.6 hours
The distance of the school from their home is 27 miles
Step-by-step explanation:
Mrs Dang drove her daughter to school at the average speed of 45 miles per hour.
Let x miles = distance from the school to their home.
Distance = speed × time
Time = distance / speed
Time used in going to school will be
x/45
She returned home by the same route. This means that distance back home is also x miles.
She returned at an average speed of 30 miles per hour.
Time used in returning home from school will be x/30
x/45
If the trip took one half hour, then the time spent in going to school and the time spent in returning is 1 1/2 hours = 1.5 hours. Therefore
x/30 + x/45 = 1.5
(15x + 10x) /450 = 1.5
15x + 10x = 450 × 1.5 = 675
25x = 675
x = 675/25 = 27
Time it took her to get to the school will be x/45
= 27/45 = 0.6 hours
Answer:
We all experience inequality. Never have I known it to be enjoyable.
Step-by-step explanation:
Nobody is created equally and that's the cold hard truth. Each of us is born into a different story/background, with a unique set of characteristics. Often I've known inequality to lead to envy, vendettas, and insecurity.
Answer:
m/_A=112°, m/_B=68°, m/_C=112°
Step-by-step explanation:
m/_A is 112° since consecutive /_s in a parallelogram are supplementary therefore 180°(<- supplementary sum)-68°(<- m/_D)=112°(<- m/_A, and m/_C), and in a parallelogram, one main property is opposite /_s are congruent therefore m/_B is congruent to m/_D so m/_B=68°.
Hopefully, this helps you out, have a great day!

<em>sooo</em>
<em>1.50x + </em><em>3</em><em>.</em><em>0</em><em>0</em><em>= 10.50</em><em> </em>
<em>we </em><em>then </em><em>solve </em><em>it </em>
1.50x + 3.00= 10.50
-3.00 -3.00
1.50x = 7.50
