Answer: D. 143
Step-by-step explanation:
31 times 4.26 = 132.06 + 10.908 = 142.968 which simplifies to 143 because you round up.
Answer:
a. FG ≈ 6.983 cm
b. FH = 13.16 cm
Step-by-step explanation:
<h3>a)</h3>
Corresponding sides of similar triangles are proportional. This means ...
FG/GH = CD/DE
FG = GH(CD/DE) = (9.4 cm)(2.6/3.5) . . . . . . multiply by GH; fill in values
FG ≈ 6.983 cm
__
<h3>b)</h3>
And ...
FH/GH = CE/DE
FH = GH(CE/DE) = (9.4 cm)(4.9/3.5)
FH = 13.16 cm
__
<em>Additional comment</em>
Corresponding vertices are listed in the same order in the similarity statements. This means, for example, segment FG (which names the first two vertices in the name of ΔFGH) will correspond to segment CD (which names the first two vertices of ΔCDE).
Step-by-step explanation:
an object and its shadow create a right-angled triangle.
2 objects and their shadows create 2 similar right-angled triangles.
that means the angles are the same, and the side lengths of one triangle all correlate with the corresponding side lengths of the other triangle via the same factor.
so,
42 × f = 6
f = 6/42 = 1/7
the length of Joel's shadow is then
20 × f = 20 × 1/7 = 2.857142857... ft

Step-by-step explanation:
Just make a line that doesn't have a pattern like 2, 4, 6, 8 or like 6, 12, 18, 24.
99.9% sure just spamming the keyboard with random numbers will work.
