In a set of base-ten blocks, let 1 flat represents 1 unit.
a. What does 1 long represents?
b. What does 1 cube represents?
c. Represent 1.23 using the blocks with these representations.
(a)
To find:
In a set of base-ten block, 1 long represents.
Answer to Problem 1NT
Solution:
1 long represents
Explanation of Solution
Given:
In a set of base-ten blocks, 1 flat represents 1 unit.
Approach:
Write decimal in form of tenths and hundredths.
Calculation:
There are 10 block/ long in 1 flat.
Hence, 1 long/ block represents 0.1 flat.
(b)
To find:
In a set of base-ten block, 1 cube represents.
Answer to Problem 1NT
Solution:
1 cube represents
Explanation of Solution
Given:
In a set of base-ten blocks, 1 flat represents 1 unit.
Approach:
Write decimal in form of tenths and hundredths.
Calculation:
There are again 10 cubes in 1 long.
By equation (1)
Hence, 1 cube represents 0.01 flat.
(c)
To represent:
The number 1.23 using blocks.
Answer to Problem 1NT
Solution:
The representation of 1.23 is
Explanation of Solution
Given:
In a set of base-ten blocks, 1 flat represents 1 unit.
Approach:
Write decimal in form of tenths and hundredths.
Calculation:
Here
1 long = 0.1 flat
1 cube = 0.01 flat
Here 1 represent 1 flat,

- 9. (a) Use pseudocode to describe an algo- rithm for determining the value of a game tree when both players follow a minmax strategy. (b) Suppose that T₁ and T2 are spanning trees of a simple graph G. Moreover, suppose that ₁ is an edge in T₁ that is not in T2. Show that there is an edge 2 in T2 that is not in T₁ such that T₁ remains a spanning tree if ₁ is removed from it and 2 is added to it, and T2 remains a spanning tree if 2 is removed from it and e₁ is added to it. (c) Show that a degree-constrained spanning tree of a simple graph in which each vertex has degree not exceeding 2 2 consists of a single Hamiltonian path in the graph.arrow_forwardChatgpt give wrong answer No chatgpt pls will upvotearrow_forward@when ever one Point sets in x are closed a collection of functions which separates Points from closed set will separates Point. 18 (prod) is product topological space then VaeA (xx, Tx) is homeomorphic to sul space of the Product space (Txa, prod).
