7 miles:2.5 hours
10 miles:? hour

10×2.5÷7=25/7. As a result, It took him 25/7 hours or 3 4/7 hours to ride 10 miles. Hope it help!

The answer is 3.6. You have to find the unit rate for miles per hour. You divide 2.5 by 7 and you should get this long, ridiculous number. You don't have to use all that so round to the nearest hundredths to get .36. You multiply that by 10 to get the answer......3.6! :)

What is -5h-3(10+h)=-6

Crazy boy [7]

-5h-3(10+h) = -6

-5h-30-3h = -6

Add/subtract like terms

-8h -30 = -6

Add 30 to both sides

-8h = 24

Divide by -8 to isolate h

h = -3

Verify that [tan(theta) + cot(theta)]^2 = sec^2(theta) + csc^2(theta)

Wittaler [7]

(tanθ + cotθ)² = sec²θ + csc²θ

Expand left side: tan²θ + 2tanθcotθ + cot²θ

Evaluate middle term: 2tanθcotθ = $2*\frac{sin\theta}{cos\theta}*\frac{cos\theta}{sin\theta}$ = 2

⇒ tan²θ + 2+ cot²θ

= tan²θ + 1 + 1 + cot²θ

Apply trig identity: tan²θ + 1 = sec²θ

⇒ sec²θ + 1 + cot²θ

Apply trig identity: 1 + cot²θ = csc²θ

⇒ sec²θ + csc²θ

Left side equals Right side so equation is verified

A recipe for cake calls for 5.25 deciliters of milk. How many liters of milk are needed for the cake?

Aneli [31]

There are 10 deciliters in 1 liter (deci means 10).

Divide 5.25 by 10 to find how many liters are needed.

5.25/10 = 0.525

0.525 liters of milk are needed for the cake.
