Answer:

28. m<A=20°, m<B=70°

32. m<A=103°, m<B=77°

Step-by-step explanation:

complementary angle=a+b=90°

supplementary angle=a+b=180°

28. A+B=90°

      5x+17x+2=90°

      22x+2=90°

      22x=90-2

      22x=88

        22x/22=88/22

      x=88/22=4

m<A=5x=5*4=20°

m<B=17x+2=17*4+2=68+2=70°

         Check

A+B=90°

20+70=90°

90°=90°

32. A+B=180°

     x+11+x-15=180°

     2x-4=180°

     2x=180+4

     2x=184

     2x/2=184/2

     x=184/2

     x=92

m<A=x+11=92+11=103°

m<B=x-15=92-15=77°

     Check

A+B=180°

103+77=180°

180°=180°

Answer:

1. Value for which denominator is 0.

2. Value for which we get negative sing inside the root or log.

Step-by-step explanation:

Domain is the set of input values.

If a function is not defined for a set of value then they are NOT in it's domain.

Two we look for in an equation that can tell us what's NOT in it's domain :

1. Value for which denominator is 0.

2. Value for which radicand is negative because negative values inside the square roots are not real.  Value for which log values are negative because log is not defined for negative values.

Answer:

Fraction of the number that received an A= = 27/50

Step-by-step explanation:

In a class of 50 statistics​ students, 27

students received an A.

Total number of students=50

Number that received an A= 27

Fraction of the number that received an A= Number that received an A/Total number of students

Fraction of the number that received an A= = 27/50

Answer:

your answer is fifteen

Answer: Because the a-value is negative.

Step-by-step explanation:

The vertex form of a quadratic equation is: y = a(x - h)² + k    where

Given: g(x) = - (x + 1)² - 3

                    ↓

                 a= -1

Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).

Answer:

The GFC would be 8

Step-by-step explanation:

12 - 1,2,3,4,5,6,7,8,12,24

40 - 1,2,4,5,8,10,20,40

This is the same as -11x+49

=========================================================

Explanation:

1 apple = x dollars

4 apples = 4x dollars, after multiplying both sides by 4

If Jessica buys 4 apples, then she spends 4x dollars.

Jessica has $19, so she'll have 19-4x dollars leftover after buying those four apples.

Similarly, Levi will have 30-7x dollars leftover when buying 7 apples for x dollars each.

Add up the leftover amounts to get...

(jessica's leftovers) + (Levi's leftovers)

(19-4x)+(30-7x)

19-4x+30-7x

(19+30)+(-4x-7x)

49-11x

This is the same as -11x+49 since you can think of 49-11x as 49+(-11x), and we can add two terms in any order we want.

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

An alternative viewpoint

Pool up Jessica's and Levi's amount they start with to get 19+30 = 49 dollars

Jessica buys 4 apples and Levi buys 7 apples. In total, this is 4+7 = 11 apples. At x dollars an apple, they spend 11x dollars. So they'll have 49-11x dollars leftover after buying those 11 apples.

Answer:

[tex]90x[/tex]

Step-by-step explanation:

[tex]30x+60x=?[/tex]

If you want to solve this easily, you can just remove x and add 30x + 60x.

[tex]30+60[/tex]

We know that 30 + 60 is 90. So we will add x to 90.

[tex]90x[/tex]

Now you have your answer!

Hope this helps!

Answer:

90x

Step-by-step explanation:

To solve, add 30+60.

30 + 60 is equal to 90.

Add x and it will be 90x.

That is your answer!

Steps to solve:

6a + 12 = 3(2a + 1) + 5

~Distribute right sides

6a + 12 = 6a + 3 + 5

~Simplify

6a + 12 = 6a + 8

~Subtract 12 to both sides

6a = 6a - 4

~Subtract 6a to both sides

0 = 4

Therefore, there are no solutions.

Best of Luck!

The formula for the slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{20-10}{2-1}[/tex]

Answer:

  -a^5/(8b^7)

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)^c = a^(bc)

  a^-b = 1/a^b

  [tex](-2ab^{-5})(4a^{-2}b)^{-2}=(-2ab^{-5})(4^{-2}a^{-2(-2)}b^{-2})\\\\=\dfrac{-2}{16}a^{1+4}b^{-5-2}=\boxed{-\dfrac{a^5}{8b^7}}[/tex]

Hey there! I'm happy to help!

To write a fraction as a decimal, you simply divide the numerator by the denominator.

10÷18=0.55555.... (the 5s never end!)

We see that the 5s repeat forever. This means that this is a repeating decimal.

Have a wonderful day! :D

Answer:

153/40

Step-by-step explanation:

The first step to finding the fraction is to get rid of the decimal points as fractions do not have decimals. To do this we can multiply it by 1000 which gives us 3825. To have this equal to the original number we add ÷1000 on the denominator which gives us 3825/1000 which is a fraction still equal to the original number (3825÷1000=3.825). Which can further be simplified to 153/40 (both numbers divisible by 25). This is the simplest fraction which can express the number 3.825 (153/40=3.825).

Hope this helped!

Answer: REMEMBER TO RATE 5 STARS AND GIVE ME A HEART, THANKS!!!

The High Shcool Basketball team played a total of 25 games.

Step-by-step explanation:

You take the 9 from the games they won last season and divide it by .36 and that will give you the answer of 25. So 25 is the total games the "High School Basketball Team" won. If you want to double check your answer you can take the answer of 25 and times it by .36 which will equal 9.

Correct Question: Find the simplified product: [tex] \sqrt{2x^3}*\sqrt{18x^5} [/tex]

Answer:

[tex] 6x^4 [/tex]

Step-by-step explanation:

Based on the rules of radicals, since [tex] \sqrt{2x^3} [/tex] and [tex] \sqrt{18x^5} [/tex] has the same index (square root), therefore:

[tex] \sqrt{2x^3}*\sqrt{18x^5} = \sqrt{2x^3 * 18x^5} [/tex]

To simplify this, multiply their bases together, and add their exponents.

[tex] = \sqrt{2*18x^{3+5} [/tex]

[tex] = \sqrt{36x^{8} [/tex]

Simplify further

[tex] = \sqrt{36}*\sqrt{x^8} [/tex]

[tex] = \sqrt{6*6}*\sqrt{x^4*x^4} [/tex]

[tex] = 6x^4 [/tex]
