Answer:
12
Step-by-step explanation:
Let ΔABC be an obtuse triangle with sides a, b, c, that lie
opposite the angles A, B, C; with radius r of inscribed circle and
radius R of circumscribed circle; p semiperimeter. For obtuse triangle you can use all known area formulas:
1.
; (the area is equal to half of product of two sides and sine of angle that lies between these sides);
2.
;
3.
(Heron's formula);
4.
;
5.
.
Answer:
3.5p ≤ 40
Step-by-step explanation:
The inequality that best describes this problem is 3.5p ≤ 40;
Given parameters:
Total amount with me = $40
Cost per package of hot dog = $3.5
Unknown;
The inequality that represents the problem = ?
Solution:
p is the number of hotdogs that can be bought.
So, total hotdog that can be bought if each hotdog cost $3.5 per box is;
p x 3.5
Now,
this will equal the total amount at hand;
p x 3.5 ≤ 40
3.5p ≤ 40
So first fin the area then surface area and the volume
volume=legnth times width times heigh ttimes width=3 times 5 times 6=90
volume=90
surface area=(2 times 3 times 5)+(2 times 3 times 6)+(2 times 5 times 6)=(2 times 15)+(2 times 18)+(2 times 30)=30+36+60=126
volume=90
surface area=126
radio fo surface area to volume
90:126
simplify and treat as fraction
5:7
since they area all decimals they expect us to divide
5/7=.714
the closest answer is D, 0.7
the answer is D 0.7
