42 cm because if you divide 210 and 1260 it will make 6 so u just multiply it by 7 and u get 42
Answer:
<h2>a. 2,025 ft</h2><h2>b. 8,100 is a perfect square. </h2>
Step-by-step & explanation:
<em>It is a perfect square because if it wasn't, it wouldn't be equally a whole number when divided by 4 or 2,025 exactly on ALL 4 sides and when finding the root of 8,100 it's a perfect 90. As you should already know a perfect square has a given 90 degree angle.</em>
Tarp = 8,100 sq ft.
- anchored corners at the base.
- Square infield.
Well if there's 4 bases, divide 8,100 by 4.
8,100 / 4 = 2,025
One base to another base is 2,025 ft.
Make them both improper fractions.
77/10 - 19/5
Give them common denominators (multiply the second fraction by 2)
77/10 - 38/10
Subtract
39/10 = 3 9/10
question 1 is congruent. 2 is not congruent and 3 is congruent
