The equation is $b=\frac{2A}{h}$

Step-by-step explanation:

Let us revise how to make a variable subject of an equation

Write the equation and circle the variable you want to make it subject
Keep it in one side and move all other in the other side
Make the coefficient of the subject 1

∵ A = $\frac{1}{2}$ × b × h

∵ b is the subject

∴ Multiply the two sides by 2

∴ 2A = b × h

- Divide both sides by h

∴ $\frac{2A}{h}= b$

- Switch the two sides

∴ $b=\frac{2A}{h}$

The equation is $b=\frac{2A}{h}$

Inequality Show your step by step solution to this. 5-2x>17

bonufazy [111]

Answer: x<-6 *The answer should be the negative sign.*

Step-by-step explanation:

subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

subtract 5 both sides of an equation.

5-2x-5>17-5

simplify.

-2x>12

multiply by -1 both sides of an equation.

(-2x)(-1)<12(-1)

simplify.

2x<-12

divide by 2 both sides of an equation.

2x/2<-12/2

-12/2=-6

12/2=6

6*2=12

12/6=2

x<-6

Hope this helps!

Thanks!

Have a great day!

Solve the following: S5 for 600 + 300 + 150 + .

Tresset [83]

600 + 300 + 150 + . . . is a geometric sequence with a = 600 and r = 1/2
Sn = a(1 - r^n)/(1 - r)
S5 = 600(1 - (1/2)^5)/(1 - 1/2) = 600(1 - 1/32)/(1/2) = 1,200(31/32) = 1,162.5

Suppose a certain character in a role-playing game has an ability to use in battles. When activated, the ability deals damage to

Helen [10]

Answer:

The chance of getting exactly 3 hits is = 0.20

Step-by-step explanation:

P.S - The exact question is -

As given,

F(x) = 0 , x < 1

0.30 , 1 ≤ x < 2

0.56 , 2 ≤ x < 3

0.76 , 3 ≤ x < 4

0.9 , 4 ≤ x < 5

1 , 5 ≤ x

Now,

f(x) = 0.30 , x = 1

0.56 - 0.30 = 0.26 , x = 2

0.76 - 0.56 = 0.20 , x=3

0.9 - 0.76 = 0.14 , x = 4

1 - 0.9 = 0.1 , x = 5

0, otherwise

Now,

The chance of getting exactly 3 hits is = f(x = 3) = 0.20
