6 is easy
7. never divide by a fraction, flip ot upside down and multiply, so multiply by 5 on both sides
8. subtract 3.45 on both sides
9. the answer is just 1
Answer:
Cost of the first house : $480,000
Cost of the second house : $320,000
Step-by-step explanation:
An estate agent has three houses for sale. The prices of the houses were
in the ratio 6:4:3 and the cheapest house was priced at $240 000. What
were the prices of the other two houses? (SHOW WORKING)
The prices of the house has a ratio of
6:4:3
Sum total = 6 + 4 + 3 = 13
Cheapest house = $240,000
The sum total cost of the 3 houses = x
x is calculated as:
= 3/13 × x =$ 240,000
= 3x = $240,000 × 13
x = $240,000 × 13/3
x = $1,040,000
The Cost of the first house =
6/13 × $1,040,000
= $480,000
Cost of the second house
= 4/13 × $1,040,000
=$320,000
Therefore,
Cost of the first house : $480,000
Cost of the second house : $320,000
using the law of sines, you can say that f=28 units. Hope this helps
Answer:
B. 105
Step-by-step explanation:
The scale factor of the smaller figure to the larger figure is 4/25
<h3>Scale factors</h3>
Scale factors is used to enlarge or diminish the size of an object. The rato of the sides or volume of the figures is the scale factor.
Given the following
Surface area of small cylinder = 20πyd²
Surface area of large cylinder = 125πyd²
find the ratio
Scale factor = 20π/125π
Scale factor = 4/25
Hence the scale factor of the smaller figure to the larger figure is 4/25
