From the picture, we can see that ΔLSP and ΔLRN are similar, so corresponding sides are proportionate:
LN : LP = 28:12 = 7:3
Therefore, the LRN sides is 7/3 of the corresponding side of LSP.
Then, it states that the area of LSP = 50, and area of a triangle is (1/2)bh, so we set up the equation
Area of LSP = (1/2)bh = 50 ← Remember how the corresponding sides are 7/3 of LSP? Therefore, the area of LRN:
LRN = (1/2)(7b/3)(7h/3) ← Take out the 7/3 and multiply them together
= (49/9)(1/2)bh ← From LSP, we know that (1/2)bh = 50, so plug that in
= (49/9)*50 ≈ 272.222 units ²
Answer:
28
Step-by-step explanation:
1 in.=3.5
so 8×3.5=28
so it is 28 miles
Answer:
156
Step-by-step explanation:
Let the sum of the set of numbers = S
So....the mean would be calculated as the sum of the set divided by its number of entries, or :
S / 12 = 13 ....... multiply both sides by 12
S = 13 * 12 = 156 .....so.....the sum is 156
Answer:
<h2>seventeen (17),nineteen (19),and twenty three(23)</h2>
Answer:
<B = 47
Step-by-step explanation:
(5x+7) = (3x+23)
5x+7 = 3x+23
2x+7 = 23
2x = 16
2x/2 = 16/2
x = 8
<B = 3x+23
<B = 3(8)+23
<B = 24 + 23
<B = 47
