Answer: (The first number will be for the side on the left and the second will be for the on the right it matches with) (1, 3) (2, 1) (3, 5) (4,2) (5, 4)

Step-by-step explanation:

The nomial number(prefix) is determined by how many terms are in a parentheses. For example, The first one (3z) (9z) has one term bc 3z is one tern and 9z is one term so they are both monomials but b-1 would be a binomial because it has two terms so knowing that should explain my answers

Step-by-step explanation:

19.9 + 113.6 = 133.5

180-133.5= 46.5

Answer:

[C] 46.5°

Step-by-step explanation:

Given:

In triangle xyz, angle x measures 19.9° and angle

y measures 113.6°. what is the measure of angle z

Note that:

Triangle = 180 degree

Solution:
Since,

x = 19.9 degree

y = 113.6 degree

then we have:

19.9 + 133.6 + z = 180

133.5 + z = 180

Subtract both sides by 133.5

133.5 - 133.5 = 180 - 133.5

x = 46.5 degree

Hence, the measure of angle z is 46.5

Also means that [C] 46.5 is the correct answer.

Answer:

$13.50

Step-by-step explanation:

So excluding tax and tip, let's find the cost of the meal.

$6.70 + $1.95 + $2.35 =  $11.00

Now let's add the 4.5% tax. We do this by adding 4.5% of 11.00 to 11.00

$11.00 + 0.045($11.00) = $11.495 which rounds to 11.50

Now the tip is 2 dollars, so add 2 to 11.50 to get $13.50

Answer:

z° = 135°

Step-by-step explanation:

The sum of angles in an octagon

=> Sum = 180°(8 - 2)

            = 180° × 6

            = 1080°

∴Each interior angle = [tex]\frac{1080}{8}[/tex]°

                                  = 135°

∴z° = 135°

Answer:

760ft

Step-by-step explanation:

First you find the volume of the rectangle thing :)

so 14 times 19 times 2 = 532ft

than you need to do the triangle so 20 - 14 (for base length) is 6

so 19 times 6 times 2 = 228ft

now you ad them, so 532 + 228 = 760

Answer:

incorrect, is you plug in the x, y=2x-1, y=60-1, or y=59,

Answer:

Jenna is not correct.

Step-by-step explanation:

If we subsitute the y in the equation with 61 and subsitute x with 30, it would be: 61 = 30*2-1. However 30*2-1=59 therefore it is incorrect.

Answer:

P = 40 m

A = 100 m²

Step-by-step explanation:

(10√2)² = 200

side length = √100 = 10 m

P = 10 x 4 = 40 m

A = 10 x 10 = 100 m²

Answer:

The numbers are;

20 and 21

Step-by-step explanation:

A general form of an exponential decay model can be presented as follows;

f(x) = a·(1 + r)ˣ

Where;

f(x) = The output for a given input variable, 'x'

x = The input variable

a = The initial value

r = The growth (+ve) or decay (-ve) rate

When f(x) = 400, a = 1,800, r  = -7% = -0.07, we get;

400 = 1,800 × (1 - 0.07)ˣ

(1 - 0.07)ˣ = 400/1,800 = 2/9

ln((1 - 0.07)ˣ) = ln(2/9)

x = ln(2/9)/(ln(1 - 0.07)) ≈ 20.73

The value of 'x' lies between 20 and 21.

[tex]x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})(x^2y^4 - 3xy^2z^{14} + 9z^{28})[/tex]

Step-by-step explanation:

Given

[tex]x^3y^6 + 27z^{42[/tex]

Required

Factor

Express both terms as a cube

[tex]x^3y^6 + 27z^{42} = (xy^2)^3 + (3z^{14})^3[/tex]

Let

[tex]a =(xy^2)[/tex]

[tex]b = (3z^{14})[/tex]

So:

[tex]x^3y^6 + 27z^{42} = a^3 + b^3[/tex]

Using sum of cubes:

[tex]a^3 + b^3 = (a + b)(a^2 - ab + b^2)[/tex]

So:

[tex]x^3y^6 + 27z^{42} = (a + b)(a^2 - ab + b^2)[/tex]

Substitute in, values of a and b

[tex]x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})((xy^2)^2 - (xy^2)*(3z^{14}) + (3z^{14})^2)[/tex]

[tex]x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})(x^2y^4 - 3xy^2z^{14} + 9z^{28})[/tex]

Answer:

24 gallons of blue

Step-by-step explanation:

The number of gallons of blue color needed is for the mixer in which 30 gallons of yellow used, 24

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Given that,

A new color of green requires 5 yellow to 4 parts blue

The paint mixer used 30 gallons of yellow

The number of gallons of blue color needed = ?

Ratio of yellow to blue in mixture = 5/4

So, if 30 gallons of yellow is used

then gallons of blue = ?

Suppose, gallons of blue =  x

5/4  = 30/x

x  = 24

Hence, the gallons of blue is 24

Answer:

13.  PS = 21.37

14.  68.74°

Step-by-step explanation:

13.   QS/39 = tan 28

      QS = 39 tan 28

sin 76 = QS/PS

PS sin 76 = QS

PS = QS/sin 76

    = 39 tan 28/sin 76

    = 21.37

14.    tan 47 = BD/18

        BD = 18 tan 47

        cos CDB = 7/BD

                        = 7/(18 tan 47)

         m∠CDB = arccos [7/(18 tan 47)

                        = arccos .362644...

                        =  68.74°

The trigonometry we get  PS = 21.37 and  m∠CDB=  68.74°

Trigonometry finding sides and angles

We have to find

The value of tan is opposite side/adjacent side

Therefore we get

13.   QS/39 = tan 28

QS = 39 tan 28

sin 76 = QS/PS

PS sin 76 = QS

PS = QS/sin 76

PS = 39 tan 28/sin 76

PS = 21.37

14.    tan 47 = BD/18

 BD = 18 tan 47

 cos CDB = 7/BD

cos CDB= 7/(18 tan 47)

m∠CDB = arccos [7/(18 tan 47)

m∠CDB = arccos .362644...

 m∠CDB =  68.74°
