Answer:

C

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:

P = 40 m

A = 100 m²

Step-by-step explanation:

(10√2)² = 200

200/2 = 100

side length = √100 = 10 m

P = 10 x 4 = 40 m

A = 10 x 10 = 100 m²

Answer:

How would Antonio respond....she would say "Thanks for the practice ".

Tess is right about it being easy to find 10% of 46 by moving the decimal point 1 place to the left to get 4.60.....but there is no need to do that twice....because if u do 10% twice, ur doing 20%.

okay....once u get 10% of 46 = 4.60....then u figure 5% of 46 = (0.05(46) = 2.30....because 10% + 5% = 15%.....then u add those together.....4.60 + 2.30 = 6.90. This can easily be checked...15% of 46 = 0.15(46) = 6.9 ,just like 10% of 46 + 5% of 46 = 6.9

[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:

Step-by-step explanation:

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.

Step-by-step explanation:

Answer:

#2 is 2^-9.  #3 is 1/6^15. #4 is 10^8.

Step-by-step explanation:

Remember that with exponents, division is subtraction, and multiplcation is addition.

So for the first problem, 2^-5 / 2^4 is really:

2^-5-4

This is simply 2^-9 power.

Next we have (6^-3)^5. I dont mean to confuse you, so just remember. When, and ONLY when and exponent is INSIDE parentherse, can it be multplilied by another exponent that is OUTSIDE of the parenthesese. SO we can write this as:

6^-3*5

This equals:

6^-15

Which can further be simplyfied to:

1/6^15

Countinuing on we have 10^-12 / 10^-20. Since we are dividing, we subtract to exponenets. So we can write this as:

10^-12 - -20

This is just 10^8 power.

640,320

The amount of profit would the company make over the course of its first 24 years of operation should be $2,114,784.

Since annual profit is $333,500

The profit percentage should be likely 8%

And, the number of years should be 24

So, the amount of profit should be

[tex]= $333,500 * (1 + 0.08)^{24[/tex]

= $2,114,784
