Answer:

the amount after 3 weeks is $37.33

Step-by-step explanation:

Given that

His balance is -$48.82 i.e. overdraft

Now in order to get the positive balance, he plans to deposit the money of $28.55 per week

We need to find out the amount after 3 weeks

So,

= -$48.32 + $28.55 + $28.55 + $28.55

= $37.33

hence, the amount after 3 weeks is $37.33

Pls Help me with this answer
snow_lady [41]

Answer:

a. 5

b. -3

Step-by-step explanation:

a. (5*(8^1/3 + 27^1/3)^3)^1/4

= ((40^1/3 + 135^1/3)^3)^1/4

≈ ((3.42 + 5.13)^3)^1/4

≈ (8.55^3)^1/4

≈ 625^4

= 5

b. 64^-1/3*(64^1/3 - 64^2/3)

= 0.25*(4 - 16)

= 1/4 or 0.25 *-12

= -12*1 / 4

= -12/4

= -3

Hope this helped :3

A convex polyhedron has (a + 3) faces, (2a) vertices, and (4a – 1) edges. What is the value of a? a =
rusak2 [61]
Number of faces: F=a+3
Number of vertices: V=2a
Number of edges: E=4a-1

V+F-E=2
Replacing V=2a; F=a+3; and E=4a-1 in the formula above:
(2a)+(a+3)-(4a-1)=2
Eliminating parentheses:
2a+a+3-4a+1=2
Adding similar terms:
(2+1-4)a+(3+1)=2
(-1)a+4=2
Solving for a. Subtracting 4 both sides of the equation:
(-1)a+4-4=2-4
(-1)a=-2
Dividing both sides by (-1)
(-1)a/(-1)=-2/(-1)
a=2

Answer: The value of a is: a=2
