The correct answer is that Hector placed Puppy 3 at -3.4 instead of at -0.75.
So A would be your correct answer. -3/4 is equivalent to -0.75. Think of it like money. 4 quarters equals $1.00. 3 quarters is 75 cents, or .75 which is this. Don’t forget the signs though. God bless you.

Two cars start from the same point driving in opposite directions. Both cars drive 6miles. One car stops, the other car makes a
dimaraw [331]

Answer:

  • <u>14.4 mile</u>²

Explanation:

1. By driving 6 miles each, the cars will be 6 miles + 6 miles = 12 miles appart.

2. When one car stops and the other car makes a 90° left-hand turn and drive 8 miles, you can model the situation with a right triangle, where one leg is 12 miles, the other leg is 8 miles, and the hypotenuse is the distance that separates the cars.

Hence, you must use Pythagoras to find that distance.

3. Pythagoras

  • hypotenuse² = leg₁² + leg₂²

  • hypotenuse = (12 mile)² + (8 mile)² = 144 mile² + 64 mile² = 208 mile²

  • hypotenuse=\sqrt{208mile^2}=14.4mile^2, which is rounded to the neartest tenth of a mile.

Viktor [21]

Answer:

Worked 40 hrs in week

Pay $300 for week

Step-by-step explanation:

Hours: 7-11a.m = 4

12-4p.m = 4 So, 4+4=8 hrs per day

So, 8 hrs per day × 5 days a week (8×5)=40

Worked 40 hrs in week

Pay: $7.50/hr So, $7.50×40 hrs (7.50×40)=300

So, $300 pay for week
