Answer:
(B) 7.1 is the estimated square root of 50
Step-by-step explanation:
A. √50 = √2 √25
= 5√2.
Jaclyn did not take the square root of 2.
B. We estimate the square root of 2.
Trial and improvement:
It must lie between 1 and 2 so we try 1.5:
1.5 * 1.5 = 2.25
Its < 1.5 so try 1.4
1.4 * 1.4 = 1.96.
So it is a little above 1.4.
Try 1.45:
1.45 * 1.45
1.45
* 1.45
-------
725
5800
14500
2.1025
= 2.1025.
- this is above 2 so the answer is between 1.40 and 1.45 but closer to 1.4.
A good estimate is 1.42
So the square root of 50 is about 5*1.42 = 7.1
The probabilty is 6/26. i thnk im not really good with this stuff
Answer:
50 minutes = B
Step-by-step explanation:
Andre can run 5 miles in 40 minutes
for 1 miles = 40/5 = 8 minutes
1 mile = 1.61 kilometres
x = 10 kilometres
x= (10x1)/1.61= 10/1.61 = 6.21miles
- for 1 miles = 40/5 = 8 minutes
- 6.21 miles = 8 x 6.21 = 49.689 minutes ≈ 50 minutes = B
Answer: 8cm
Step-by-step explanation:
If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.
