Find the value of x explain how you got your answer ​
aliya0001 [1]

Answer:

step 1: x+50+4x=90

the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.

step 2: x+50+4x=90

                  x+4x=50

                      5x=50

                        x=10

then you solve the equation, x is 10

You deposit $5000 in an account earning 3% interest compounded monthly. How much will you have in the account in five years?
rusak2 [61]

Answer:

$5808.08

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r/m)^mn

FV = Future value  

P = amount deposited = $5000

R = interest rate  = 0.03  

N = number of years  = 5

m = number of compounding = 12

5000 x (1 + 0.03/12)^60 = $5,808.08

Enter and solve a polynomial equation for the situation described.
klasskru [66]

Height = x (This is given)

Length = 5x

Width = 6x

Volume = length × width × height

The equation will be: (5x)(6x)(x) = 1920

simplify:

30x² × (x) = 1920

30x³ = 1920

Divide both sides by 30

x³= 64

x = ∛64

x= 4

If x = height, then, the height is 4cm

5x = length

20cm = length

6x = width

24cm = width
