Find the arc length of AB. Round answer to nearest tenth.

Answers

Answer 1

Answer:

Answer:

9.8 inches

Step-by-step explanation:

The formula for arc length is (θ/360)2πr

This is where θ represents the measure of the central angle in degrees,

and r represents the radius of the circle.

This said, we can plug our values in.

(80/360)2π7

Simplify.

(2/9)14/π

28/9π

9.7738438112

Round to nearest tenth.

9.8

Answer 2

Answer:

Answer:

9.8 inches

Step-by-step explanation:

Set up a proportion:

central angle / 360 = arc length / circumference

$(80)/(360)$ = $(x)/(14\pi )$

360 divided by 14pi is about 8.2, so divide 80 by 8.2 to find x.

x = 9.8 in

right triangle
from base of triangle to wall=a
from floor to top of ladder on wall=b
legnth of ladder=c

legnth=12=c
base is 3 feet away=a
use pythagorean theorem
a^2+b^2=c^2
3^2+b^2=12^2
9+b^2=144
subtract 9
b^2=135
square root both sides
b=√135=3√15

the height is 3√15 feet

What formula tells the cost, in dollars, if chocolate chip cookies are $2.50/ dozen and lemon frosteds are $1.50/dozen? let c=number of dozens of chocolate chip cookies;L=number of dozens of lemon frosted; T= total charge

Answers

c= # of dozens chocolate chip cookies= $2.50/dozen

L= # of dozens of lemon frosted= $1.50/dozen

T= total charge

Multiply the number of dozens of chocolate chip cookies by the cost per dozen. Multiply the number of lemon frosted by the cost per dozen. Add those two together to equal the total cost.

T= ($2.50 * c) + ($1.50 * L)
T= $2.50c + $1.50L

ANSWER: T= $2.50c + $1.50L

A while back, either James borrowed $12 from his friend Rita or she borrowed $12 from him, but he can't quite remember which. Either way, he is planning to pay her back or ask that she pay him back this afternoon. If he has $42.80 in his wallet, which equation represents the amounts of money he may have after he sees Rita?

Answers

He will either have $54.80 or $30.80 in his wallet. Also, the question says, how much money will he have after, not how much will he have in his wallet after..... so you just write x as its unknown how much other money he has.... just saying
