Answer 1

Answer:

38.4º

Step-by-step explanation:

Use Law of Cosines

c² = a² + b² - 2ab*cosC

12² = 17² + 19² - 2(17)(19)*CosC

Simplify

144 = 289 + 361 - 646 * cosC

144 = 650 - 646 * cosC

Subtract 650 from both sides

-506= -646 * cosC

Divide both sides by -646

0.7832817337 = cosC

Take the arcsin of 0.7832817337

38.4º = C

---------------------------------

Cheaters Solution!!!

Instead of doing the math you could think it through.

Since FD is less than 17

∠E must be less than 45º

So the answer must be A. 38.4º

One moving company charges 100$ plus 10$ per hour. Another company charges $50 plus $15 per hour. At what number of hours will the charge by both companies be the same?

Answers

The answer is: 12.5 hours

The answer is ten hours because 10*10=100+100=200 so if 15*10=150+50=200 they are the same so the answer is 10 hours

What is the solution for this system of equations?

(1,5)
(6, – 4)
(-4, 6)
(5, 1)

Answers

Step-by-step explanation:

y = x - 4

y = -x + 6

x - 4 = -x + 6

x + x = 6 + 4

2x = 10

x = 10/2 = 5

y = x - 4

y = 5 - 4

y = 1

Solution = (5,1)

Answer:

The sector for 126 rubies would measure 126 degrees.

Step-by-step explanation:

First, a pie-chart is a circle, and there are 360 degrees in a circle. Because there are 320 total gemstones, 1 gemstone maps to 1.125 degrees. That is, 1.125 degrees per gemstone.

[tex]360\div320=1.125[/tex]

Knowing that, you can calculate the degrees in the pie-chart for any given number of gemstones. Just multiply the gemstones by 1.125.

[tex]112\times1.125=126[/tex]

The sector for 112 rubies would measure 126 degrees.

If you want to be extra sure, you can calculate that for all types of gemstones and add them up:

[tex]32\times1.125=36\\112\times1.125=126\\96\times1.125=108\\64\times1.125=72\\16\times1.125=18\\36+126+108+72+18=360[/tex]

That confirms they all add up to 360 degrees.

How many 1/8th are in 1 2/16

Answers

Answer:

Step-by-step explanation:

2/16 can be rewritten into 1/8

so 1 1/8 is 9/8

So there are 9 1/8ths in 1 2/16

Hope this helps!

(This is all copied and pasted. The right answer though! Trust me!)

If there are x times 1/8 gives 1/2 then

x × 1/8 = 1/2

Then x = 4

if we take 4 times 1/8 then

1/8 + 1/8 + 1/8 + 1/8 Or. 4 × 1/8 gives

4/8 = 1/2

Similarly we can get 1/2 by only adding 4 times 1/8

Write a function that represents the relationship between X and y shown in the graph below

Answers

Answer:

y = 3x - 10

Step-by-step explanation:

Find the slope of the line by calculating the Rise/Run between any two points. I picked (-2,-16) and (4,2).

The Rise is = (2-(-16))=18

The Run is = (4 -(-2)) = 6

Rise/Run is 18/6 = 3. The slope is three:

y = 3x + b

b is the y-intercept, the value of y when x=0. b is - 10 in this graph.

y = 3x - 10 is the line of this graph.

Help, I know you could find the slope on any two points but the way they graphed it made it super confusing, is this supposed to trick me?

what is the answer to 5a+3b=c

Answers

Answer:

a = -0.6b + 0.2c

Step-by-step explanation:

Simplifying

5a + 3b = c

Solving

5a + 3b = c

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-3b' to each side of the equation.

5a + 3b + -3b = -3b + c

Combine like terms: 3b + -3b = 0

5a + 0 = -3b + c

5a = -3b + c

Divide each side by '5'.

a = -0.6b + 0.2c

Ann earned $752+x in a month

If you take t as hours he worked as tutor then ,

Money earned will be $752+t

Answer:

earnings = 752 +t

Step-by-step explanation:

If Ann worked t hours as a tutor, then she worked (94-t) hours as a waitress. Her total wages were ...

earnings = waitress wages + tutor wages

earnings = 8(94 -t) + 9(t)

earnings = 752 +t . . . . . . . simplify

the diagonals of a rhombus are 16 cm and 12cm. find its length

Answers

Answer:

l=10 cm

Step-by-step explanation:

In a rhombus, the diagonals are cut into identical lines at the intersection.

This way, I found the measures of the halves of the diagonals in a right triangle, knowing that the diagonals of the rhombus are perpendicular on each other.

I calculated that AO = AC/2= 8, and that BO=BD/2= 6, and then I applied pytagora's theorem in a quarter of the rhombus, which is the right triangle AOB, to find the length of a side

what are the zeros of the polynomial function ? f(x) = 2x (x-2) (1-x)

Answers

Answer:

The zeros are 0 ,2, and 1

Step-by-step explanation:

f (x) = 2x (x - 2) (1 - x)

set f(x) equal to y

y = 2x (x - 2) (1 - x)

solve when y is 0 because when y is 0 then it is an x-intercept

0 = 2x (x - 2) (1 - x)

separate all of the equations out

0 = 2x

0 = (x - 2)

0 = (1 - x)

solve for x for each equation

0 = 2x

divide both sides by 20/2 = 0 and 2x/2 = x0 = xx = 0

0 = (x - 2)

add 2 to both sides0 + 2 = 2 and (x - 2) + 2 = x2 = xx = 2

0 = (1 - x)

subtract 1 from both sides0 - 1 = -1 and (1 - x) - 1 = -x-1 = - xmultiply both sides by -1-1 · -1 = 1 and -x · -1 = x1 = xx = 1
