My brain refuses to work because I can only think of Diagon Alley
Korolek [52]

Answer:

30 cm

Step-by-step explanation:

1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal  

h, l and w are known; discover V, S and d  

V = lwh  

S = 2(lw + lh + wh)  

d = √(l2 + w2 + h2)  

2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal  

S, l and w are known; discover h, V and d  

h = (S - 2lw)/(2l + 2w)  

V = lwh  

d = √(l2 + w2 + h2)  

3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal  

V, l and w are known; discover h, S and d  

h = V/lw  

S = 2(lw + lh + wh)  

d = √(l2 + w2 + h2)  

4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal  

d, l and w are known; discover h, V and S  

h = √(d2 - l2 - w2)  

V = lwh  

S = 2(lw + lh + wh)

3x + fraction 1 over 4 y^2 what is the value expression above when x=3 and y=4? Must show all work and calculations
evablogger [386]

Answer: 9 1/16

nine and one sixteenth

Step-by-step explanation:

Substitute x = 3 and y = 4 into the equation:

3x + 1/4^y

= 3(3) + 1/4^(2)

Then solve using the order BEDMAS (brackets, exponenets, division, multiplication, addition, subtraction).

= 3(3) + 1/4^(2)

= 3(3) + 1/16

= 9 + 1/16

= 9 1/16

You invest $1,300 in an account with an annual interest rate of 2.5%, compounded monthly. How much money is in the account after
wariber [46]
Hi there
The formula is
A=p (1+r/k)^kt
A future value?
P present value 1300
R interest rate 0.025
K compounded monthly 12
T time 15 years
So
A=1,300×(1+0.025÷12)^(12×15)
A=1,890.75

Good luck!
