Given:
Total number of marbles in the bag = 150
There are 21 blue marbles for every 4 white marbles.
To find:
The number of blue marbles in the bag.
Solution:
Since, there are 21 blue marbles for every 4 white marbles, therefore the ratio of blue marble to white marbles is 21:4.
Let the number of blue marbles be 21x and white marbles be 4x.
Total number of marbles in the bag = 150
Divide both sides by 25.
Now,
Therefore, the number of blue marbles is 126.
Answer: Angle 4
Step-by-step explanation:
The angle of depression is formed by the line of sight and the horizontal line tangent to the top of the observer.
The base length is 5.5 cm.
Explanation:
Area of triangle = base x height x 1/2
Let b cm be the base length of the triangular flag.
22 = b x 8 x 1/2
22 x 2 ÷ 8 = b
b = 44 ÷ 8
b = 5.5
Okay. 12 - 4 is 8. For the other question, you have to multiply the difference of that by 1/4. 8 * 1/4 is 2. The expression of (12 - 4) is four times the value of 1/4 * (12 - 8). and 2 is 1/4 the value of 8. The answers to this question are A , B, and C.
