30 miles in 40 minutes

since we need to know how many miles in 1 minute, divide both by 40 so that it goes down to 1 minute.


30/40=.75 miles/min or 3/4 miles/min

Brooke cooked a 4/1/3-pound lasagna in 1/1/3 hours. How many hours per pound did it take to cook the lasagna?
Hitman42 [59]

Answer:

4/13 hours

Step-by-step explanation:

Total pounds of lasagna = 4 1/3 pounds

Total time taken to cook = 1 1/3 hours

How many hours per pound did it take to cook the lasagna?

Hours per pound of lasagna = Total time taken to cook / Total pounds of lasagna

= 1 1/3 hours ÷ 4 1/3 pounds

= 4/3 ÷ 13/3

= 4/3 × 3/13

= 4/13 hours

It will take 4/13 hours to cook each pound of the lasagna

Find the square of the leg b of this right triangle: a=2b, c=10
Pepsi [2]
A² + b² = c²

a = 2b, c = 10

(2b)² + b² = 10²

4b² + b² =100

5b² = 100

b² = 100 ÷ 5

b² = 20

Well to find the range, you need to take the highest number and subtract the lowest from it:

3 - -97
3 + 97
100

Range is always positive!

PLEASE HELP! Explain
skelet666 [1.2K]

Answer:

x=17

Step-by-step explanation:

See those same little "triangles" on each right end of the horizontal lines? That means that the horizontal lines are parallel. And the vertical line that passes through both of them is called a transversal. Whenever we have that situation - where parallel lines are being intersected by a transversal - we can then know which angles are equal to each other using some postulates.

The angles with the given equations shown are corresponding angles. We know this because they are in the same matching corners created by the intersections. And by using the Corresponding Angles Postulate, which states that corresponding angles are congruent (or equal) we then know that 5x-25 and 3x+9 must be equal to each other, too.

From there, we can set up an equation to find x. Just set them equal to each other like so and solve:

5x-25=3x+9

2x -25 = 9

2x = 34

x = 17

Therefore, x = 17. Please don't hesitate to ask any questions!
