Answer:
1.5
Step-by-step explanation:
base x height x 0.5
Pythagorean theorem: c^2 - a^2 = b^2
b = square root of (2.5)^2 - (1.5)^2
= 2
b = height
area = 0.5 x 1.5 x 2 = 1.5

- There are no mosquitoes when rainfall is about 4 cm
Step-by-step explanation:
I took the quiz.
Answer:
Step-by-step explanation:
Let the x be the number of months.
In x months, xian will have:
(52+16x) stamps
and kai will have:
(76+12x)stamps
To find out how many months they will have the same number of stamps, we evaluate the two expressions:
52+16x=76+12x
52+4x=76
4x=24
x=6
So xian and kai will have the same number of stamps after 6 months.
Using either of two expressions, each will have:
52+16(6)=76+12(6)= 148 stamps.

The two angles are identical:
3x -7 = 2x + 7
Add 7 to both sides:
3x = 2x + 14
Subtract 2x from both sides:
X = 14
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
