Out of the choices given, the gemstones had approximately 20 edges. This correct answer is D, 20. The answer can be figured out by using " Euler's Polyhedral Formula." The correct formula for this particular question is shown here; <span>F = 12, V = 10 V - E + F = 2 10 - E + 12 = 2 -E + 22 = 2 -E = -20 E = 20. I hope that helps you. </span>

David works six more hours per week than Xavier. If Xavier works 32 hours a week, what is the total hours the two work in a
Finger [1]

We are required to find the total hours David and Xavier works in a week

The total hours David and Xavier works in a week is 70 hours

let

number of hours Xavier works = 32 hours

number of hours David works = (6 + 32) hours

= 38 hours

<em>Total number of hours David and Xavier works in a week = number of hours Xavier works + number of hours David works</em>

= 32 hours + 38 hours

= 70 hours

Therefore, the total hours David and Xavier works in a week is 70 hours

Find all possible values of the digits Y, E, A, R if YYYY - EEE + AA - R = 1234, and different letters represent different digit
schepotkina [342]

Answer:

Y:  2

E:  9

A:  1

R:  0

Step-by-step explanation:

If we used the value  Y = 2,   E = 9  , A = 1  and R = 0

in the given equation i.e

YYYY - EEE + AA - R = 1234.

From LHS,

Putting the value of Y,E, A and R in the given question we get

2222-999+11-0\\=\ 1223\ + 11\\=\ 1234

=RHS

Therefore\  the\  value\  of \   Y, E, A, R\  is\  2\ , \  9 , \ 1\   and\  0
