<h3>
Answer: E) x^5</h3>
=====================================================
Explanation:
We simply take half of the exponent 10 to get 5. This applies to square roots only.
So the rule is 
A more general rule is
![\sqrt[n]{a^b} = a^{b/n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5Eb%7D%20%3D%20a%5E%7Bb%2Fn%7D)
If n = 2, then we're dealing with square roots like with this problem. In this case, a = x and b = 10.
Answer:
- perimter of original rectangle = <u>17. 6 mm</u>
- side length of the enlarged rectangle = <u>23. 22 mm</u>
- perimeter of the enlarged rectangle = <u>95. 04 mm</u>
Step-by-step explanation:
<u>PERIMETER</u><u> </u><u>OF</u><u> </u><u>ORIGINAL</u><u> </u><u>RECTANGLE</u>
- Length of original rectangle = 4.5 mm
- Width of original rectangle = 4.3 mm
<em>perimeter = 2 × ( length + width)</em>
= 2 × ( 4.5 + 4.3)
= 2 × 8.8
= 17. 6 mm
<u>SIDE</u><u> </u><u>LENGTH</u><u> </u><u>OF</u><u> </u><u>ENLARGED</u><u> </u><u>RECTANGLE</u>
- Width of original rectangle = 4. 5 mm
- Width of enlarged rectangle = 24.3 mm
Enlargement factor = 24.3 / 4.5
= 5.4
- Length of original rectangle = 4.5 mm
- Enlargement factor = 5.4
Side length of enlarged rectangle
= original length × Enlargement factor
= 4.3 × 5.4
= 23. 22 mm
<u>PERIMTER OF ENLARGED RECTANGLE</u>
= 2 × ( enlarged ength + enlarged breadth)
= 2 × (23. 22 + 24. 3 )
= 95. 04 mm
Answer: 1 : 1.48
Step-by-step explanation:
Adam was able to change £400 into 592 francs which means that the British pound is stronger because it was able to buy more Swiss francs.
The exchange rate can be gotten using direct proportion:
400 : 592
1 : x
Cross multiply:
400x = 592
x = 592/400
x = 1.48
Exchange rate is:
= 1 : 1.48
Answer:
The median of the data set:
6, 15, 30, 45, 47, 49
The middle numbers are 30 and 45 so
You have to do 30 + 45
= 75
Then do 75 ÷ 2
= 37.5
The mean of the data set:
47, 15, 6, 49, 45, 30 (add them all)
= 192
Then divide 192 by 6 (because there are 6 numbers)
192 ÷ 6
= 32
So the median is 37.5 and the mean is 32.
Step-by-step explanation:
