What's 15/11 and a mixed number?

Answers

15/11 is a mixed number already, it is 1.363636363636........

Answer:

[tex]1\frac{4}{11}[/tex]

Step-by-step explanation:

You can read [tex]\frac{15}{11}[/tex] as "15 divided by 11"

So to figure out the mixed number, you do just that.

11 goes into 15 1 time, then you subtract 11 from 15, which gives you a remainder of 4. You put 4 as your numerator and 11 is your denominator.

I've attached an image that shows the math. Hope that helps!

Find the measure of the missing angle.

Answers

Answer:

34

Step-by-step explanation:

if you add 90+56 you get 146 and then 180-146=34

Answer:

a = 34°

Step-by-step explanation:

1. We know that the straight line is a straight angle (180°), and the right angle is worth 90°.

2. This means that a + 90 + 56 = 180.

3. (Solving equation above).

Step 1: Simplify both sides of the equation.

[tex](a)+(90+56)=180[/tex] [tex]a + 146 = 180[/tex]

Step 2: Subtract 146 from both sides.

[tex]a+146 - 146 = 180 - 146[/tex] [tex]a = 34[/tex]

Step 3: Check if solution is correct.

[tex](34) + 90 + 56 = 180[/tex] [tex]124 + 56 = 180[/tex] [tex]180 = 180[/tex]

Therefore, a = 34°.

How do you know whether an equation is an​ identity? How many solutions does an identity​ have? Explain. Choose the correct answer below.

A. An equation is an identity if it can be rewritten as 0=0. Such an equation has only one​ solution, 0, and that is the identity of the variable.

B. An equation is an identity if it can be rewritten as an equation of the form ​"variable​number," such as x5 or y3. Such an equation has only one​ solution, and the solution is called the identity of the variable.

C. An equation is an identity if it can be rewritten as an equation of the form ​"variable​number," such as x5 or y3. Such an equation has an infinite number of solutions because a variable can be any number.

D. An equation is an identity if it can be rewritten as 0=0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable.

Answers

Answer:

Option D

Step-by-step explanation:

A. An equation is an identity if it can be rewritten as 0=0. Such an equation has only one​ solution, 0, and that is the identity of the variable.

Incorrect. In this case there are infinite solutions.

B. An equation is an identity if it can be rewritten as an equation of the form ​"variable​number," such as x5 or y3. Such an equation has only one​ solution, and the solution is called the identity of the variable.

Incorrect. There might be more than one solution and the equation is not an identity.

C. An equation is an identity if it can be rewritten as an equation of the form ​"variable​number," such as x5 or y3. Such an equation has an infinite number of solutions because a variable can be any number.

Incorrect. There might be one or no solution and the equation is not an identity.

D. An equation is an identity if it can be rewritten as 0=0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable.

I have a bag of marbles, where each marble is pink or yellow. The ratio of pink marbles to yellow marbles is 3:5 If there are total of 72 marbles in the bag, how many are pink?

Answers

Answer:

i think its 27.

Step-by-step explanation:

Let the number of pink marbles  =  p

Let the number of yellow marbles  =  y

The ratio of pink marbles to yellow marbles is 3:5 . This means...

the number of pink marbles / the number of yellow marbles  =  3 / 5

p / y  =  3 / 5

There are a total of 72 marbles in the bag. So...

the number of pink marbles  +  the number of yellow marbles  =  72

p + y  =  72

y  =  72 - p

Now we can use this value of  y  in the first equation and solve for  p .

p / (72 - p)  =  3 / 5

Multiply both sides of the equation by  5 .

5p / (72 - p)  =  3

Multiply both sides by  (72 - p)

5p  =  3(72 - p)

5p  =  216 - 3p

Add  3p  to both sides.

8p  =  216

Divide both sides by  8 .

p  =  27

the number of pink marbles  =  27

Find the area of each triangle. Round your answers to the nearest tenth. Show all your work

Answers

Answer:

1st question: 30

2nd question:78

Step-by-step explanation:

use the formula [tex]A=\frac{ab}{2} sin(y)[/tex]]

Where A is the area, a and b are the two given lengths and y is the given angle.

So,

a=9

b=7

y=73

Plugging those values in, we get:

[tex]A=(\frac{9*7}{2})Sin73\\=31.5(Sin73)\\=30.1\\=30 (rounded)[/tex]

For the 2nd question, we use the same formula, only this time

a=13

b=14

y=59

so,

[tex]A=\frac{13*14}{2} sin(59)\\A=91*Sin(59)\\A=78[/tex]

A gym employee earns the same amount each month. After working for three months, he earned $4,500. Complete the table to determine how much money he will make over a five-month period. on. 8.If his pay rate remains the same, how much will he earn after working 7 months?

Answers

Answer:

Each month he earn $1,500 a month because $4,500 divided by 3 is $1,500. So in 5 months he will make $7,500. On the 7th month he will have $10,500.

The money that the gym employee earns in 1 month will be; $1500. The money that the gym employee earns in 5 months will be; $7500.

How to calculate the value?

The gym employee earns the same amount each month and after working for three months, he earned $4,500.

In this given problem, the amount that he earns monthly would be

= Total amount / Number of months

= $4500 / 3

= $1500

Thus He earns $1500 monthly.

The money that; the gym employee earns in 5 months would be:

= 5 × $1500

= $7500.

Hence, The money that the gym employee earns in 1 month will be; $1500. The money that the gym employee earns in 5 months will be; $7500.

simplify (x - y)^2 - 2(x - y) + 1

Answers

Answer:

(x-y-1)^2 or [(x-y)-1]^2

Step-by-step explanation:

We are given the expression:-

Let A = (x-y)^2

[tex] \displaystyle \large{ A^{2} - 2 A+ 1 }[/tex]

From:-

[tex] \displaystyle \large{ {x}^{2} - 2x + 1 = {(x - 1)}^{2} }[/tex]

Find the equation of the line that
is perpendicular to y = –
-x and
contains the point (4,-8).
y=
x + [ ]

Answers

Answer:

y = 3x/2-14

Step-by-step explanation:

We are given that the line is perpendicular to y = -2/3 and contains (4,-8).

Perpendicular Def.

[tex] \displaystyle \large{m_1m_2 = - 1}[/tex]

Both slopes multiply each others equal to -1.

Finding another slope that is perpendicular to -2/3, substitite m1 = -2/3 in.

[tex] \displaystyle \large{ - \frac{2}{3} m_2 = - 1}[/tex]

Multiply both sides by 3.

[tex] \displaystyle \large{ - \frac{2}{3} m_2( 3) = - 1(3)} \\ \displaystyle \large{ - 2 m_2= - 3} \\ \displaystyle \large{ m_2= \frac{3}{2} }[/tex]

Therefore, another slope that is perpendicular to -2/3 is 3/2.

Then rewrite in slope-intercept form.

Slope-Intercept

[tex] \displaystyle \large{y = mx + b}[/tex]

where m = slope and b = y-intercept; substitute m = 3/2 in.

[tex] \displaystyle \large{y = \frac{3}{2} x + b}[/tex]

Since the line contains (4,-8), substitute x = 4 and y = -8 in and solve for b.

[tex] \displaystyle \large{ - 8 = \frac{3}{2} (4) + b} \\ \displaystyle \large{ - 8 = 3(2)+ b} \\ \displaystyle \large{ - 8 = 6 + b} \\ \displaystyle \large{ - 8 - 6 = b} \\ \displaystyle \large{ - 14 = b}[/tex]

Therefore, b is -14; rewrite again in slope-intercept form.

Thus:-

[tex] \displaystyle \large{y = \frac{3}{2} x + b} \\ \displaystyle \large{y = \frac{3}{2} x - 14}[/tex]
