Answer:
D 60
Step-by-step explanation:
Fist we can determine y
7y+5y = 180 since it is a straight line
12y = 180
Divide each side by 12
12y/12 =180/12
y = 15
We also know that 5y+3y +x = 180 since the angles of a triangle add to 180
8y +x = 180
8*15 +x = 180
120+x = 180
Subtract 120 from each side
120-120+x = 180-120
x = 60
The surface area of the sphere:
A = 4 r² π
1 ) r = 60 m;
A = 4 · 60² π = 4 · 3600 π = 14,400 π m²
2 ) Diameter of 14 cm:
r = 14 cm / 2 = 7 cm
A = 4 · 7² π = 4 · 49 π = 196 π cm²
D is the answer to your question
Answer:
A 2 ounce bag costs $1.2.
Step-by-step explanation:
With the information provided, you can use a role of three to find the cost of a 2 ounce bag given that you know that a six ounce bag costs $3.60.
6 ounce bag → 3.60
2 ounce bag → x
x=(2*3.60)/6
x=7.20/6
x=1.2
According to this, the answer is that a 2 ounce bag costs $1.2.
