Answer:

B.  One-fourteenth

Step-by-step explanation:

The obriens are buying new windows for their house. The company installs the new windows for 2100 the total cost for buying the windows and having them installed is 5323.50 of the o'briens pay 230.25 per window how many windows did they buy

Answers

Answer:

14

Step-by-step explanation:

Given that:

Cost of purchase and installation = 5323.50

Cost per window = 230.25

Cost of installation = 2100

Hence,

Total purchase cost of windows alone :

5323.50 - 2100 = 3,223.50

Therefore, the number of windows purchased is :

(Total purchase cost of windows alone / price per window)

(3,223.50 / 230.25)

= 14

Hence, 14 windows was purchased

What is 149/15 as a mixed number?

Answers

Answer:

its an improper

mixed : 9 14/15

Step-by-step explanation:

its a mixed number if the number at the tops in the limit and there is a number at the side that represents whole number(s)

Answer:

the answer is 9 14/15

Step-by-step explanation:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 149 by 15 and keep only what is to the left of the decimal point:

149 / 15 = 9.9333 = 9

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

149 - (15 x 9) = 14

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 149/15 as a mixed number is:

v=u + at
u= 2
a= -5
t = 1/2
Work out the value of v.

Answers

Answer:

V= -1/2

Step-by-step explanation:

You would have to add U+AT to get V

If A=-5 and T=1/2, then -5*1/2= -2.5 (A*T)

Then, adding U (which is 2), gives -.5, or -1/2

The value of the digit in the hundreds place in the number 587,349 is 1/10 the value of the digit in the thousands place in which number? *

Answers

Answer:

3000 is your answer

Step-by-step explanation:

The 3 in the hundreds place if the number 587,349 has a value of 300. This 300 is 1/10 the value of the number you're looking for, so if x is the number you're looking for, then

[tex]300 = \frac{1}{10} x[/tex]

[tex]300 \times 10 = \frac{1}{10} x \times 10[/tex]

[tex]3000 = x[/tex]

x is your answer.

The total cost of renting a banquet hall is a function of the number of hours the
hall is rented. The owner of the banquet hall charges $45 per half hour up to a
maximum of 5 hours and a $50 cleaning fee. The equation used to express the
situation is C = 45h + 50, where h is the number of half hours. What is the
greatest value in the range for this situation?

Answers

9514 1404 393

Answer:

  $500

Step-by-step explanation:

The greatest rental time is 5 hours, which is 10 half-hours. The value of C for h=10 is ...

  C = 45·10 +50 = 450 +50 = 500

The greatest value in the range for this situation is $500.

Lines MN and PQ are parallel. Lines RS and TV intersect them. Which statements are true about these lines? Select three options. The slope of line MN is Two-thirds. The slope of line PQ is undefined. The slope of line RS is Negative three-halves. Lines RS and TV are parallel. Line RS is perpendicular to both line MN and line PQ.

Answers

Answer:

hello your question is incomplete attached below is the missing diagram

answer :

RS is perpendicular to line  MN and line PQ  

The slope of line MN is 2/3

The slope of line RS is  -3/2

Step-by-step explanation:

The slope of line MN is 2/3

slope of MN = [tex]\frac{3-(-1)}{3-(-3)}[/tex]  =  4/6 =  2/3

The slope of line RS is  -3/2

slope of RS = [tex]\frac{-2-1}{2-0}[/tex] = -3/2  this shows that Line RS are perpendicular

Lines RS is perpendicular  to MN and PQ

 lines RS is perpendicular to MN and PQ because it's sign is opposite hence it is perpendicular to MN and PQ

Answer:

The slope of line MN is Two-thirds.

The slope of line RS is Negative three-halves.

Line RS is perpendicular to both line MN and line PQ.

Answer: A quadratic equation (also called a parabola)

Step-by-step explanation:

A line can be written as:

f(x) = a*x + c

This is a polynomial with degree 1.

Now, of we have two lines:

f(x) = a*x + c

and:

g(x) = d*x + e

And we multiply them, we will get:

f(x)*g(x) = (a*x + c)*(d*x + e) = a*d*x^2 + a*e*x + c*d*x + c*e

We can rewrite this as:

                                           = (a*d)*x^2 + (a*e + c*d)*x + (c*e)

This is a polynomial of degree = 2, this is a quadratic equation, then if you multiply two lines together, you get a quadratic equation (or a parabola)
