Answer:

1000 miles

Step-by-step explanation:

We will use the distance equation to find the answer to this problem.

D = RT

Where

D is distance

R is rate

T is time

At 250 miles per hour, suppose it takes t hours to go to st. paul. Thus, we can write:

D = 250t

Now, at 200 mi per hour, it takes 1 hour longer, so the time is "t + 1", so we can write:

D = 200(t+1)

We can equate both and see:

250t=200(t+1)\\250t=200t+200

Now, we solve for t first:

250t=200t+200\\250t-200t=200\\50t=200\\t=\frac{200}{50}\\t=4

We want the distance of St. Paul, so we can use any equation. lets use the 1st equation:

D = 250t

we know t = 4

so

D = 250 * 4 = 1000 miles

Distance to St. Paul is 1000 miles

<span>If dog food costs $2 a pound and Cara buys 9 pounds, her expenditure on dog food is 9 x 2. This makes $18. If she has a total budget of $25 and spends $18 on dog food, she has $7 left over for treats (25 - 18 = 7). At $1 each, she can buy up to 7 treats.</span>

Amanda leaned a 15-foot ladder against the top of her house so she could get on the roof, which is 12 feet from the ground.
valentinak56 [21]

If you're trying to find the missing side of the "triangle" (the distance from the house to where the ladder touches the ground), you would use the pythagorean theorem, a²+b²=c². (c is always hypotenuse)

a²+b²=c²

12²+b²=15²

144+b²=225

b²=81

√b²=√81

b=9
