Pls mark me brain list.
Answer:
9 m²
Step-by-step explanation:
s = half the perimeter = (a+b+c)/2
the perimeter in our case is
a+b+c = 16
so, s = 16/2 = 8
and the sides are
7 m
6 m
16 - 7 - 6 = 3 m
therefore, we get
area = sqrt(8(8-7)(8-6)(8-3)) = sqrt(8×1×2×5) = sqrt(80) =
= 8.94427191... ≈ 9 m²
21. <DBE and <ABE are both equal halves of <ABD, so in this case, m<ABE = m<DBE, so all you have to do is solve the equation:
6x + 2 = 8x - 14
add 14 to both sides, subtract 6x from both sides.
16 = 2x
Divide both sides by two. The solution is x = 8. To find m<ABE, replace x with 2, so your final answer is 14. m<ABE = 14
22. From what we know from 21, m<ABE = m<EBD, so keep that in mind. We still have to solve for m<EBD. Since one line is 180 degrees, we are able to write out this equation using the information given:
180 = 9x - 1 (m<ABE) + 9x - 1 (m<EBD) + 24x + 14 (m<DBC)
simplify this:
180 = 12 + 42x
subtract 12 from both sides, then divide by 42.
4 = x
Now we plug this in.
4 × 9 = 36. 36 - 1 = 35.
m<EBD = 35
23. From the past two equations, we know m<ABE consistently equals m<EBD. This means that, if they are bisectors of a right angle, they both equal 45 degrees. here is our equation:
45 = 13x - 7.
we add seven to both sides and divide by 13.
4 = x
Answer: Hello! I believe your answer would be 162.
Step-by-step explanation: So the formula for Area on a rectangle is WxL. So length will be 9. But if you notice on the scale rectangle the width is the length times two. So the length on the real garden is 18.
Answer:
To do this you want to divide 7560 by 4. This leaves you with 1845. Therefore, you need 1845 4-inch stacks to build that high. You are not done though. You need to multiply 1845 by 58. This gives you 107,010. It would take 107,010 quarters to get to the top.
