Answer:

I believe it is the 3rd one down

Step-by-step explanation:

Because the two angles make an angle of 180, supplementary angles make one angle of 180 and it says that 2 and 3 are alike because they make a supplementary angle and there is a line dividing them that looks like both angles = 90 degrees

Write equivalent fractions for 7x + 4x + 3 - 1

Jobisdone [24]

14/2x = 7x
8/2x = 4x
6/2 = 3
2/2 = 1
14/2x + 8/2x + 6/2 - 2/2 = 7x + 4x + 3 - 1

Between what two numbers is the exact product of 379 and 8

ANEK [815]

"Product" means to multiply, so you have to multiply 379 by 8 to get 3,032; it's between the numbers 3,031 and 3,033

A student cuts pieces of ribbon to decorate a banner the first piece of ribbon is 24 inches long. The next piece of ribbon is on

kumpel [21]

Answer:

Option D) 47.25 in

Step-by-step explanation:

we know that

The equation of a exponential decay function is equal to

$y=a(1-r)^x$

where

y is the total length

x is the number of pieces of ribbon

a is the initial value

r is the rate of change

we have

$a=24\ in\\r=50\%=50/100=0.50$

substitute

$y=24(1-0.50)^x$

$y=24(0.50)^x$

we have that

For x=0 -----> $y=24\ in$

For x=1 ----> $y=24(0.50)^1=12\ in$

For x=2 ----> $y=24(0.50)^2=6\ in$

For x=3 ----> $y=24(0.50)^3=3\ in$

For x=4 ----> $y=24(0.50)^4=1.5\ in$

For x=5 ----> $y=24(0.50)^5=0.75\ in$

Adds the length of the first 6 pieces of ribbon

$24+12+6+3+1.5+0.75=47.25\ in$

Bearings are tricky and I though I had this

Leya [2.2K]

Answer:

241°

Step-by-step explanation:

You are given the triangle internal angle (N) at Naples = 46°, and the side opposite a = 765 km. You are given the side b = 515 km, and asked to find an angle related to the internal angle opposite (C).

By the law of sines, the internal angle (C) at Canton is ...

sin(C)/b = sin(N)/a

C = arcsin((b/a)sin(N)) = arcsin(515/765·sin(46°)) ≈ 28.964°

The bearing from Elgin to Canton will be 270° less this angle, so is about 241°.

_____

Comment on your answer

Apparently, you added 29° to 270°, rather than subtracting. Since the direction from Elgin to Canton is south of west, the bearing angle must be between 180° and 270°. Note that a line west from Elgin will be parallel to the line east from Canton, so you can take advantage of alternate interior angles being congruent where the Elgin-Canton line crosses those parallel east-west lines.
