The value of x is 60
<h3>How to determine the value of x?</h3>
The complete question is added as an image
From the image, we have:
ABD = 30
DBC = x
The sum of complementary angles is 90.
So, we have:
30 + x = 90
Subtract 30 from both sides
x = 60
Hence, the value of x is 60

Answer: If he has 3 mystery books, and those are 1/8 of his whole collection, he has 24 books.
Step-by-step explanation:
3 = 1/8 × x
multiply both sides by the reciprocal of 1/8 which is 8/1 ("flipped fraction")
8 × 3 = 8/1(1/8) x <em>When you multiply a fraction by its reciprocal, it produces 1, so it "cancels" in the multiplication</em>
<em>24 = x </em>
<em>This may seem complicated, but understanding the process will help you solve more complicated questions like this in the future, I hope.</em>

6.7 x -2.3 = -15.41. The hundredth value is two spaces right of the decimal. To round to the nearest hundredth, you look at the number after it in the thousandth spot. if it is less than 4 then the hundredths remains the same, if it is more than 4, then you round up the number in the hundredths spot. There is no number in the thousandth spot (0) so the answer remains -15.41
Answer:
119.43cm^2
Step-by-step explanation:
The computation of the area of the shaded region is shown below:
As we know that
= Area of the rectangle - Area of the circle
where,
Area of rectangle is


= 132 cm^2
And, the area of the circle is

Now the area of the shaded region is

= 119.43cm^2
We simply deduct the area of the circle from the area of the rectangle so that the area of the shaded region.
