Answer:
B and D.
Step-by-step explanation: Just took the test.

We have to find the simplest ratio between length, breadth and the height.
Here,
- Length = 10 cm
- Breadth = 15 cm
- Height = 25 cm
Note:
- Always check the units first.
- Then find the HCF of the numbers to simplify them into the simplest ratio.
So,
HCF of 10, 15 and 25 is 5. Cancelling with respect to 5.
Then, the ratio will be 2:3:5 (Option A)

Hey I feel, I had the same issue. Here's the thing, math doesn't always make sense. Just remember that anything that has to do with circles (like cones) utalizes the radius, not the entire diameter
Answer:
AB=6 Units
Step-by-step explanation:
Given the following lengths of rectangle ABCD and its dilation A'B'C'D' respectively
- A'B' = 15 Units
- B'C' = 9.5 Units
- BC = 3.8 units
We are to determine the length of AB. To do this, we first determine the dilation factor.

Therefore:

I'll do this step-by-step. Note, ratios are basically division signs.
The ratio of cars to motorcycles in a parking lot is 10:3, which means there are 10 cars for every 3 motorcycles.
The ratio of motorcycles to vans is 2:3, there are 2 motorcycles for every 3 vans.
There are 30 vans, so there are 20 motorcycles, since 20 motorcycles:30 vans is equal to 2 motorcycles: 3 vans in fractions. (20 / 30 = 2 / 3)
So, the ratio of cars represented by x to the number of motorcycles, 20 can be written as x / 20 = 10 / 3. 10 / 3 is 3.333, meaning 3.333 cars per 1 motorcycle, so multiply 20 by 3.333 to get x, which is 66. There are 66 cars and 30 vans, so there are 33 more cars than vans in the parking lot. 66/20 = 10/3, both have a ratio of 3.33 when divided.
If you don't want the explanation, there are 33 more cars than vans in the parking lot.
