Answer:
25% should go
Step-by-step explanation:
If she wants to save $2,400;
Then in a month, she should save 2400/12 = 200
So now we need the amount of her monthly earnings will this savings be
That will be;
200/800 * 100%
= 1/4 * 100% = 25%
Answer:
72 yd / min
Step-by-step explanation:
The first thing is to fully calculate the distance traveled, each lap is 200 yards and how 6 laps would be:
200 * 6 = 1200
Now, let's divide the race into how the statement tells us:
1200 * 2/3 = 800
1200 * 1/3 = 400
That is, in the first 800 yards it goes to 80 yd / min and then in the remaining 400 yards it goes to 60 yd / min, let's calculate the time Rhea lasted:
800/80 = 10 min
400/60 = 6,667 min
Which means that in total it would be:
10 + 6,667 = 16,667
In other words, Rhea took 16,667 minutes to travel 1,200 yards, so the speed would be:
1200 / 16,667 = 72
Therefore the average Rhea speed was 72 yd / min
A fraction is bigger than a negative number. This is because, a negative number is below zero, while a fraction is greater than zero.
Answer:
$5.78
Step-by-step explanation:
Multiply both sides of the equation by 28 4y+7=10
Then move constants to the right side and change its sign 4y=10-7
Now subtract the numbers 4y=3 divide both sides by 4 so your answer is y=3/4
