Answer:
C
Step-by-step explanation:
The circumference (C) of a circle = 2πr ← r is the radius
Given C = 15π the equating gives
2πr = 15π ( divide both sides by 2π )
r = 
= 7.5 cm
The area (A) of a circle is calculated using the formula
A = πr² = π × 7.5² = 56.25π cm² → C
Answer:
Angle 1 and Angle 2 are adjacent angles.
A straight line is 180°, so you can do:
109 + ? = 180 (? is the top angle of the triangle)
? = 71°
Because the triangle is an isosceles triangle, the other angle is 71° too.
71 + 71 + ? = 180
? = 38
You subtract 38 with 90 to find the other angle.
90 - 38 = 52°
To find ∠2 you subtract 52 with 180.
180 - 52 = 128
∠2 = 128
128 = 11x + 18
110 = 11x
10 = x
Answer:
I think its choice C
Step-by-step explanation:
Because it makes more sense to me
5 * 1.5 to get 7.5, which is total pounds
7.5 - 2.8 to get how many almonds
= 4.7
Choice C makes the most sense to get that answer
i'm only in 5th grade so tell me if i'm wrong ill be ok with that
Answer:
1
Step-by-step explanation:
3x+5=8
Group like terms
3x=8-5
3x=3
Divide both side by the co-efficient of x which is 3
3x/3=3/3
x=1
