Step-by-step explanation:
Steps Ex. 1 Ex. 2
Round a number to the nearest tenth 3.14 .883
Find the hundredths' place. 3.14 .883
Less than 5, round the tenth down. 3.1
If it is 5 or more, round the tenth up. .9
That is your explanation. The answer is .9
Answer: 96 miles
Step-by-step explanation: 120 divide by 55= 2.18. So you multiply 44 by 2.18
In the given diagram, the length of diagonal IE is 30. The correct option is (2) 30
<h3>Calculating the length of a diagonal of a Rhombus </h3>
From the question, we are to determine the length of diagonal IE
From the given information,
/TG/ = 16
∴ /RG/ = 16÷2 = 8
NOTE: The diagonals of a rhombus bisect each other at right angles
Then,
/GE/² = /ER/² + /RG/² (<em>Pythagoras' theorem</em>)
From the given information, the perimeter of the rhombus is 68
Since all the sides of a rhombus are equal to one another,
Then,
/GE/ = 68÷4
/GE/ = 17
Thus,
17² = /ER/² + 8²
289 = /ER/² + 64
/ER/² = 289 - 64
/ER/² = 225
/ER/ = √225
/ER/ = 15
But,
/IE/ = 2 × /ER/
∴ /IE/ = 30
Hence, the length of diagonal IE is 30. The correct option is (2) 30

Answer:
The numbers are x = 3 and y = 1. Therefore the value of xy is 3.
Step-by-step explanation:
In order to calculate the numbers we will simplify the equation, this is done bellow:
2*x + x(2^2) + (y*2^3) + (y*2^4) = 42
2*x + 4*x + 8*y + 16*y = 42
6*x + 24*y = 42
We can divide the whole equation by 6, so we have:
x + 4*y = 7
The only possible combination of numbers that are positive and integers that will make the equation valid is x = 3 and y = 1. Therefore he value of xy is 3.
