42 wheels=21 bikes
51-42=9
9/3=3 tricycles
Answer: 48 cubes in the new box
Step-by-step explanation:
Doubling the length and the width is 2×2, so 4 times the original capacity.
4×12 = 48
It is not necessary to compute the volume. The dimensions could be anything. It's the number of cubes that count.
The given sequence is neither arithmetic nor geometric.
Further explanation:
In order to check whether a sequence is geometric or arithmetic we have to find the common ratio and common difference respectively
Common difference is the deifference between cunsecutive terms of a sequence while common ratio is the ratio between two consecutive terms.
Common difference is denoted by d and common ratio is denoted by r
- If the common difference is same then the given sequence is an arithmetic sequence
- If the common ratio is same then the given sequence is a geometric sequence
Given
1, 3, 6, 10, 15
Common difference:
Here

As the common difference is not same, the given sequence is not an arithmetic sequence
Common Ratio:

As the common ratio is also not same the sequence is not a geometric sequence.
The given sequence is neither arithmetic nor geometric.

Answer:
x = 6, z = 5.66 to nearest hundredth.
y = 90 degrees.
Step-by-step explanation:
From the chord intersection theorem 12*4 = 8 * x
So x = 6.
By the tangent / chord theorem:
z^2 = 2 * (12+4)
z^2 = 32
z = 5.66.
I'm not 100% sure of the value of angle y but I think its
1/2(100 + 80) = 90 degrees.
I'll try and check that out.
Yes that is right.
