J = K (1+ p/100) make p as a subject

olganol [36]

Answer:

p = 100(J/K - 1)

Step-by-step explanation:

When we want to make a variable the subject of an equation, we want to get that variable by itself on one side of the equation - to unwrap it from all the operations attached to it.

Here's what the process looks like for p:

$J=K(1+p/100)\\J/K=1+p/100\\J/K-1=p/100\\p=100(J/K-1)$

A train traveled 63.75 miles at a rate of 85 miles per hour. Which equation can be used to find h, the number of hours it took t

sashaice [31]

Answer: 63.75 = 85h

Solving gives 0.75 hours.

Step-by-step explanation:

we now that speed = distance / time

therefore time will be Distance / speed

Given that distance = 63.75miles

Speed= 6=85miles per hour

Time(h) = 63.75miles/ 85.---- equation 1

But from the options given, the equation that can also be used to find number of hours is

63.75 = 85h

such that making h subject of formula still give us

h= 63.75/85 as in equation 1 above

solving gives that Time ( h) = 0.75 hours .

The sum of the measures of the angles of a triangle is 180 degrees°. The smallest angle of the triangle has a measure one fourth

vivado [14]

Answer:

8°,32°,140°.

Step-by-step explanation:

Sum of measure of angles of a triangle is 180°

Let the second smallest angle be x°

Smallest angle= $\frac{1}{4}$ x

Largest angle= 5 x- 20°

A T Q

x+ $\frac{1}{4}$ x + 5x-20= 180°

$\frac{4x+x+20x}{4}$ = 180+ 20

$\frac{25x}{4}$ = 200

x= $\frac{200}{25}$ × 4

x= 32°'

Smallest angle is 32°

Hence, the smallest angle is $\frac{1}{4}$ x= $\frac{1}{4}$ ×32°= 8°

Largest angle is 5x- 20= 5×32- 20= 140°
