Answer:
Problem 15)
$40.91
Problem 16)
12.446 cm^2
Step-by-step explanation:
Problem 15)
Gala.
12.8 * 1.35 = 17.28
Honeycrisp.
9 * 1.68 = 15.12
Fuji
7.4 * 1.15 = 8.51
17.28 + 15.12 + 8.51 = 40.91
Problem 16)
(area1) + (area2) + (area3) = (total area)
(1.25*4.38) + (1.36*2.15) + (1.14*3.55) = x
5.475 + 2.924 + 4.047 = x
12.446 = x
Answer:
3) 16.2
Step-by-step explanation:
The supplement to the 115° angle on the right is 65°, the same as the angle at upper left. The vertical angles at C are the same measure, so this tells you that the two triangles FCB and ACD are similar by the AA similarity postulate. That being the case, corresponding sides are proportional:
CB/CD = CF/CA
CB = CD·CF/CA = 7.2·21.6/9.6
CB = 16.2
_____
When given two "point-to-point" triangles like this, quite often there is some sort of similarity relationship involved. First, you need to figure out what it is; then you need to make use of it as needed to answer the question being asked.
Since it is a square, all sides are equal.
Divide the 440 by 4 to find the length of each side.
440/4 = 110 yards
