Quadrilateral A has side lengths 2,3,5 and 6. Quadrilateral B has side lengths 4,5, 8 and 10. Could one of the quadrilaterals be

Makovka662 [10]

Answer:

No

Step-by-step explanation:

Given

Quadrilateral A: 2,3,5 and 6

Quadrilateral B: 4,5, 8 and 10

Required

Determine if one is a scale of another

To do that, we have to divide the corresponding lengths to give ratio.

Considering Side of A = 2 and Side of B = 4

$Ratio = \frac{B}{A}$

$Ratio = \frac{4}{2}$

$Ratio = 2$

Considering Side of A = 3 and Side of B = 5

$Ratio = \frac{B}{A}$

$Ratio = \frac{5}{3}$

$Ratio = 1.67$

There's no need to check further, since the two ratios calculated so far do not have the same value;

<em>Hence, one quadrilateral is not a scale of the other</em>

What constant term should be used to complete the square? x 2 - 5x + _____ = 7

amm1812

The quadratic equation in its generic form is:
ax2 + bx + c
To complete squares we must add the following term:
(b / 2) ^ 2
The equation is:
ax2 + bx + c + (b / 2) ^ 2
We have the following equation:
x ^ 2 - 5x + k = 7
By completing squares we have:
x ^ 2 - 5x + (-5/2) ^ 2 = 7 + (-5/2) ^ 2
Rewriting:
x ^ 2 - 5x + 6.25 = 7 + 6.25
Answer:
A constant term should be used to complete the square is:
6.25

Alice and Bob are playing a game. Alice starts first. On Alice's turn, she flips a coin. If she gets a heads, she wins. If not,

trapecia [35]

Answer:

The probability that Alice wins the game= $\frac{1}{2}$

Step-by-step explanation:

We are given that Alice and Bob are playing a game .

We have to find the probability that Alice wins the game .

If Alice win when she gets head and lose when she gets tail.Bob wins when she gets tail and she lose when she gets head.

Total results in a coin=Head, tail=2

Number of head in a coin=1

Number of tail in a coin= 1

Probability is defined as the possibility of an event that occurred

$P(E)=\frac{Number\;of\;favourable\;cases}{total\;of\;cases}$

The probability that Alice wins the game= $\frac{Number\;of\;favourable\;cases}{Total\;number\;of\;cases}$

The probability that Alice wins the game= $\frac{number \;of \;heads}{Total\; results}$

The probability that Alice wins the game= $\frac{1}{2}$

12 and 35 Pythagorean theorem

Natali [406]

Answer:

Hypotenuse = 37

Step-by-step explanation:

Let the base is 12 and height is 35.

We can use Pythagorean theorem to find the third side (hypotenuse or the longest side). The Pythagoras theorem can be given by :

$H^2=b^2+h^2\\\\H^2=12^2+35^2\\\\H^2=1369\\\\H=\sqrt{1369} \\\\H=37$

Hence, the hypotenuse is 37 units.
