Answer:

C. $11.55

Step-by-step explanation:

First, multiply 4 by $0.85 to get an answer of $3.40. Next, multiply 6 by $1.25 to get an answer of $7.50. Add up the cost of the pencils and pens by adding $3.40 and $7.50 to get $10.90. Next, we have to add the tax. Multiply $10.90 by 0.06 to get $.65. Add the $.65 to the $10.90 for a grand total of $11.55. Hope this helps!

Help pleaseeeeeeeeeeee

Answer:

x = 1

GF = 12

GH = 15

FH = 3

Step-by-step explanation:

G___F___H

GH = GF + FH

11x +4 = ( 3x +9) + (5x-2)

11x+4= 8x + 7

11x - 8x = 7-4

3x = 3

x =3/3

x = 1

GF = 3x + 9 = 3(1)+9=3+9=12

GH = 11x +4= 11(1)+4=11+4 = 15

FH = 5x - 2 = 5(1) - 2 = 5 - 2 = 3

I hope I helped you^_^

A circle has a radius of 6 cm.
Lapatulllka [165]

Answer:

1.5\pi cm

Step-by-step explanation:

A central angle measuring 45^\circ is \frac{45^\circ}{360^\circ}=\frac{45}{360}, or \frac{1}{8} of the entire circle. The circumference of the circle is given by the formula 2\pi r, which is 12\pi.

Then, the length of an arc measuring \frac{1}{8} of the entire circle is 12\pi\cdot\frac{1}{8}=1.5\pi cm.
