Answer:
log₉2873 ≈ 3.6242
Step-by-step explanation:
First off all you can estimate by applying a fundamental property of a logarithm
QS = 11x - 57
since r is the midpoint, QR + RS = QS
<h2> answer:</h2>
62.8 cm
<h2 /><h2>explanation:</h2>
circumference = 2πr
=2 × 3.14 × 10
= 62.8 cm
Its you will be found and the equation answer is 56
Answer:
230cm²
Step-by-step explanation:
The shape can be split into two shapes horizontally: a triangle and a rectangle.
<u>Area of the rectangle</u>
The area of a rectangle = length × width
In this case, the length is 20cm and the width is 7cm. 20 × 7 = 140cm²
<u>Area of the triangle</u>
The area of a triangle = 1/2 × base × height
In this case, the base is 20cm and the height is 9cm (16cm - 7cm). 1/2 × 20 × 9 = 90cm²
<u>Area of the shape</u>
To find the area of the total shape, we can add 140cm² and 90cm² to get 230cm².
Hope this helps!
