How many times longer is the length of the rectangle compared to the width? 14.4cm by 1.6cm

1 answer:

4 0

The answer is 8.

Explanation:

To find this out we would first subtract the width (1.6) from the length (14.4). 14.4 - 1.6 = 12.8. If we want to find out how many times which is how many time 1.6 to get 12.8, we would divide 12.8 by 1.6. The quotient is 8. Therefore, the length of the rectangle is 8 times that of the width.

I hope I helped and good luck!

To Enter the value of n that makes the equation: 4^5.4^n=4^8 true

irina1246 [14]

$4^2\text{ }\times4^n=4^8$

Since both sides have the same base (4), we can add the exponents

$4^{5+n}=4^8$ $5+n=8$

subtract 5 from both sides:

$5+n-5=8-5$ $n=3$

Let sets A and B be defined as follows.

VashaNatasha [74]

<h3>Given</h3>

Set A: A = {-26, -25, -24, -23, - 22, - 21}
Set B: B ∈ {x: x is even, x ≥ 6 and x ≤ 20}

<em />

<em>Cardinality means the number of elements in the set.</em>

Cardinality of the set A:

n(A) = 6, since we can count 6 elements.

Set B has even numbers between 6 and 20, both included:

B = {6, 8, 10, 12, 14, 16, 18, 20}

Then its cardinality is:

n(B) = 8

To solve this we need to compare the elements of sets A or B with numbers given:

-22 ∈ A, True ⇒ -22 is listed as element of A
6 ∈ B, True ⇒ 6 is listed as element of B
- 21 ∉ A, False ⇒ - 21 is listed as element of A
2 ∈ B, False ⇒ 2 is not listed as element of B
