Answer:
94.2 cm
62.8 inch
Step-by-step explanation:
The circumference of a circle is 2πr, where r is the radius.
The diamater is twice the radius, d=2r.
1) 2π·15 ≈ 94.2 cm
2) r = 10 inch. 2π·10 = 62.8 inch.
D) 9 because 1.45 divided by 5 = 0.29
if you move to the hundredths place (9) and its not 2 because, 2 is in the tenths
Answer:
y = -29/19 and x = -44/19
Step-by-step explanation:
3x + 2y = -10 multiply by -2 ⇔ -6x - 4y = 20
2x - 5y = 3 multiply by 3 ⇔ <u> 6x - 15y = 9 </u>
Add the two equation -19y = 29
y = -29/19
Use equation one and solve for x
3x + 2(-29/19) = -10
3x - 58/19 = -10
3x = -10 + 58/19
3x = -190/19 + 58/19
3x = (-190 + 58)/19
3x = -132/19
x = - 132/ 19 ÷3 
x = -44/19
[2*(10 + 5)] - 5
[2*(15)] - 5
[2(15)] - 5
[30] - 5
25
Area of a Trapezoid can be defined by:
A =

just substitute given information

8.1 = .75(b₁ + 6.7)
8.1 = .75b₁ + 5.025
8.1 - 5.025 = .75b₁
3.075 = .75b₁

4.1 = b₁
the other base is equal to 4.1
