Answer: 13 and 14 degrees

Step-by-step explanation:

Answer:

Step-by-step explanation:

x+6 = -6+4x

4x-x = 6+6

3x = 12

x =12/3

x = 4

Substituting x into the value of CH:

-6+4(4)

= -6 + 16

CH = 10

Answer:[tex]g (f (x)) = 3^{2} + 24[/tex]

Step-by-step explanation:

The true about the solutions of the equation f(x) = g(x) is

The solution of the graph where the graph of function intersect at

x = 1 and x = 3.642.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

We have function,

f(x) = log(x - 1)

g(x) = 1/3x² - 4

As, f(x) = g(x)

log (x-1) = 1/3 x² - 4

Now, putting x= 1, x= 3.642, x= 4.464, x= 4 , x= 0.422 into the formula for the observation.

So, the solution of the graph where the graph of function intersect at

x = 1 and x = 3.642

Answer:

x = 20

Step-by-step explanation:

since the triangle is a right angle, that means the angle is 90 degrees

equation:

30 + 3x = 90

subtract 30 on both sides

30 - 30 + 3x = 90 - 30

3x = 60

then divide each side by 3

[tex]\frac{3x}{3} = \frac{60}{3}[/tex]

x = 20

Answer:

225 hamburgers

Step-by-step explanation:

system of equations:

h + c = 390

c = h-60

use Substitution:

h + h - 60 = 390

2h - 60 = 390

2h = 450

h = 225

D

Step-by-step explanation:

Answer:

D is the correct answer :)

Step-by-step explanation:

Hi,

Twice a number is 2x (x because we don't know what that number is) The word "difference" suggests we're subtracting. So, 2x - 16 = 30 is correct.

Answer:

20.283

Step-by-step explanation:

1) the formula of the required Area is:

A=A₁+A₂, where A₁ - area of semicircle, A₂ - area of rectangular;

2) the radius of the semicircle is: r=(7-2-1)/2=2 cm, then the area A₁:

A₁=0.5*π*r²=2π≈6.283 (cm²);

3) A₂=7*2=14 (cm²);

4) finally, A=A₁+A₂=6.283+14=20.283 (cm²)

Answer:

  x = 8.2

Step-by-step explanation:

As indicated on the supplied diagram, the measure of arc GH is ...

  GH = 360° -83° -115° = 162°

The inscribed angle at F is half this measure, so we have ...

  (10x -1)° = 162°/2

  10x = 82 . . . . . . . . add 1 and simplify

  x = 8.2 . . . . . . . . . divide by 10

Answer:

  x = 62

Step-by-step explanation:

The angle marked x° is shown as the complement of the angle marked 28°. This means ...

  x = 90 -28 = 62

Step-by-step explanation:

3/4x2/1=3/2=1 1/2

Answer:

3/2 or 1 1/2

Step-by-step explanation:

Hi,

3/4 divided by 1/2 is the same thing as 3/4 x 2/1. (when dividing fractions, flip the second fraction) When you do this, you simply multiply straight across. So...

3/4 x 2/1 = 6/4

Simplify...

3/2 (both 6 and 4 can be divided by 2)

3/2 = 1 1/2

Answer:

Step-by-step explanation:

1)  

we are given ∠17  and the Adj = 200 meters they want to know the Opp

so use  TOA

Tan(17) = Opp / 200

200*Tan(17) = Opp

61.146 = Opp

the mast stands 61.1 meters tall   ( rounded to nearest 10th )

2)

now we know the opp = 40 meters and the angle is 35° and Adj = x

Use TOA again, but w/ the different knowns

Tan(35) = 40 / Adj

Adj = 40 / Tan(35)

57.1259 = Adj

so the boat is 57.1 meters from the cliff  ( rounded to nearest 10th)

3)

we are given two triangles now and are told to find the difference between them to find the distance between the buoys

Opp = 70

∠A = 60

∠B = 40

we want to find the Adj for each so use TOA

for A , then

Tan(60)= 70/a

a = 70 / Tan(60)

a = 40.4145

for B, then

Tan(40) = 70 /b

b = 70 / Tan(40)

b = 83.4227

so subtract  a  from b

83.4227 - 40.4145 = 43.008

so from buoy A to buoy B is 43.0 meters ( rounded to nearest 10th )

Answer:

Bailey's balance after 180 days is $ 157.39.

Step-by-step explanation:

Since Bailey wanted a new pair of shoes, and she put the $ 142 cost on her credit card, but because Bailey has been irresponsible with her credit, the credit card company charges her 22% annual interest, for figure Bailey's balance after 180 days, assuming she made no payments, the following calculation must be made:

365 = 100

180 = X

180 x 100/365 = X

18,000 / 365 = X

49.31 = X

22 x 0.4931 = 10.84

142 x 1.1084 = X

157.39 = X

Thus, Bailey's balance after 180 days is $ 157.39.
