22. I = Prt; P What do I first? It says to solve the equation for the given variable.

3 0

the first thing you need to do is

divide the whole equation by rt as shown below

$\frac{i}{rt} = \frac{prt}{rt}$

then you cancel out. leaving

$\frac{i}{rt} = p$

which is the same as

$p = \frac{i}{rt}$

-144r = -12rk find the value

OLga [1]

k = 12

cancel out the r on both sides

then divide -144 by -12.

you get 12.

IrinaK [193]

Dale drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 7 hours. when dale drove home, there was no traffic and the trip only took 5 hours. if his average rate was 18 miles per hour faster on the trip home, how far away does dale live from the mountains? do not do any rounding.

Answer:

Dale live 315 miles from the mountains

Step-by-step explanation:

Let y be the speed of Dale to the mountains

Time taken by Dale to the mountains=7 hrs

Therefore distance covered by dale to the mountain = speed × time = 7y ......eqn 1

Time taken by Dale back home = 5hours

Since it speed increased by 18 miles per hour back home it speed = y+18

So distance traveled home =speed × time = (y+18)5 ...... eqn 2

Since distance cover is same in both the eqn 1 and eqn 2.

Eqn 1 = eqn 2

7y = (y+18)5

7y = 5y + 90

7y - 5y = 90 (collection like terms)

2y = 90

Y = 45

Substitute for y in eqn 1 to get distance away from mountain

= 7y eqn 1

= 7×45

= 315 miles.

∴ Dale leave 315 miles from the mountains

Find m angle f to the nearest degree

dimaraw [331]

Answer:

∠F ≈ 53°

General Formulas and Concepts:

Trigonometry

sin∅ = opposite over hypotenuse
sin inverse evaluates "backward" to find the measure angle

Step-by-step explanation:

Step 1: Define

Looking at ∠F

opposite leg of ∠F = ED = 8

hypotenuse = FE = 10

Step 2: Find m∠F

Substitute: sin∠F = 8/10
Simplify: sin∠F = 4/5
Take sin inverse: ∠F = sin⁻¹(4/5)
Evaluate: ∠F = 53.1301°
Round: ∠F ≈ 53°

Twenty-four students brought their permission slips to attend the class field trip to the local art museum. If this represented

lukranit [14]

If 24 students went on a field trip, and 24 students represented eight tenths of the class, then $24 = \frac{8}{10}x$ .
First, multiply by 10 on both sides.
240 = 8x
Divide by 8 on both sides.
x = 30.

The class has 30 students in all.
This is, however, only the equation way to solve.
