Answer:

(3x + 18) + 93 = 180

23 + X

Step-by-step explanation:

(3x + 18) + 93 = 180, its supplymentery

180 - 93 = 87

87 - 18 = 69

3x = 69

69/3 = 23

23 = X

Answer:

Step-by-step explanation:

Remark

You have to assume nothing you should have to assume. You have to assume that 93 degrees on 3x + 18 sit on the same straight line. If it just looks that way, you are on shaky ground. You must be told. It's a good thing to keep in mind. Likely you'll get more questions like this. Just be aware you should not have to assume anything to make the problem work.

If the two angles both have one leg on what is marked as a straight line, then the sum of the two angles must = 180

Solution

The first one is not true. 3x + 18 is smaller than 90 degrees because 93 is more than 90 degrees. If A is true then the line is bent a bit.

B is not true. We just found one equation that doesn't work.

C is not true either. The result of trying to solve C will make x minus because 93>90 and 18 when subtracted  makes 3x even more minus.

D is true

(3x + 18) + 93 = 180               Subtract 93 from both sides.

(3x + 18) + 93-93 = 180 - 93   Combine

(3x + 18) = 87                           Remove the brackets

3x + 18 = 87                             Subtract 18

3x+18-18 = 87-18                

3x = 69                                    Divide by 3

3x/3 = 69/3

Answerx = 23

E is not true because D is true.

Answer:

The answer is actually B

Step-by-step explanation:

the top layer is 5 x 5 x 2

the bottom layer is 5 x 2 x 10

5 x 5 = 25 and 25 x 2 = 50

5 x 2 = 10 and 10 x 10 = 100

100 + 50 = 150

The length of arc UT in the diagram given, to the nearest tenth, is calculated as: 3.9 meters.

Length of arc = ∅/360 × 2πr

Given the following:

Radius = 1/2(VS) = 1/2(12) = 6 meters

∅ = 90 - (180 - 127) = 37°

Length of arc UT = ∅/360 × 2πr = 37/360 × 2π(6) = 3.9 meters

Answer:

C.  -3 and 4

Step-by-step explanation:

In order to factor a quadratic equation in the form [tex]ax^2+bx+c[/tex]
we need to find a pair of numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex].

Therefore, in order to factor [tex]x^2+x-12[/tex] we need to find a pair of numbers that multiply to -12 and sum to 1.

The only pair of numbers in the table that sum to 1 are:

p = -3 and q = 4

Step-by-step explanation:

The balance of an account earning compound interest is given by the formula ...

  A = P(1 +r/n)^(nt)

where P is the principal invested at annual rate r for t years, compounded n times per year.

__

You have P=1580, r=0.10, n=365, t=7, so the balance is ...

  A = $1580(1 +0.10/365)^(365×7) ≈ $3181.42

Step-by-step explanation:

the answer is the litter B

Answer:

B.) Graph B

Step-by-step explanation:

You can determine which is the correct graph by verifying the points on the graphs with the equation. Remember, the leftmost number in the parentheses is the "x-value" and the rightmost number is the "y-value".

Graph B has the points (0,2) and (2,6) on the line.

y = 2(0) + 2

y = 2

y = 2(2) + 2

y = 4 + 2

y = 6

As you can see, when the "x-values" are plugged into the equation, the value generated matches the "y-value" of the point. Not all the points on the other graphs are accurate according to the equation. You can prove this to yourself by following the same method as above.

Answer: 15.095$

Step-by-step explanation:

Answer:

Its like how much you multiply the original shape by, to the new one.

For example, if your new shape is double the size of the original shape, then the scale factor is 2, because you would multiply the original by 2, to get the size of the new.

However, if your new shape is half the size, then the scale factor is 1/2, as you multiply the original by half to get the new shape.

The height of the guest in inches will be 68.93 and in feet is 5.7.

It states that in the right angle triangle the hypotenuse square is equal to the sum of the square of the other two sides.

By applying the Pythagorean theorem:-

P²  =  H²  - B²

P²  = 84²  -   48²

P²  =  4725

P = √4725

P = 68.73 inches

Now the height in feet will be 68.73  /  12  = 5.7 feet.

Therefore the height of the guest in inches will be 68.93 and in feet is 5.7.

#SPJ1

Step-by-step explanation:

imagine that point (-2, -5) on the coordinate grid.

in what quadrant is it ?

it is, where both x and y are negative : the bottom left (3rd) quadrant.

and this is the same quadrant for the circle and the placement of the angle of the point on the circumference to the x-axis (the basic diameter).

what signs do sine and cosine of angles in the third quadrant have ?

sine goes below the x-axis and is therefore negative.

cosine is to the left of the y-axis and is therefore negative.

that eliminates answer c (with positive sine and cosine values).

as tan(x) = sin(x)/cos(x)

and

cot(x) = cos(x)/sin(x)

both, tan and cot, must be positive (-/- = +).

that eliminates answers a and d.

but there is also a problem with the remaining answer b :

cot(x) = 1/tan(x), as the above definitions tell us.

but answer b says that they are both 5/2. and that cannot be.

so, there is no correct answer option.

therefore, let's calculate the real results, and then you need to find the right option in the original problem definition without typos.

the point again is (-2, -5). x = -2, y = -5.

the center of the circle is at the origin.

so, the radius of the circle is per Pythagoras

r = sqrt(x² + y²) = sqrt((-2)² + (-5)²) = sqrt(4 + 25) = sqrt(29)

sin(angle) = y/r = -5/sqrt(29) = -5×sqrt(29)/29

cos(angle) = x/r = -2/sqrt(29) = -2×sqrt(29)/29

tan = sin/cos = -5/sqrt(29) / -2/sqrt(29) = -5/-2 = 5/2

cot = cos/sin = -2/sqrt(29) / -5/sqrt(29) = -2/-5 = 2/5

csc(angle) = r/y = sqrt(29)/-5 = -sqrt(29)/5

sec(angle) = r/x = sqrt(29)/-2 = -sqrt(29)/2

again, except for the error in answer b about cot, it would all point to answer b.
