Algebra applications: find the value of x and y​

Mathematics
1 answer:
strojnjashka [21]4 years ago
5 0

Answer:

x = 10°

y = 35°

Step-by-step explanation:

9x + 20 + 7x = 180 (supplementary angles)

16x = 180 - 20

16x = 160

x = 10°

2y = 7x ( opposite angles)

2y = 70

y = 35°

Find all real zeros of the function y= -9x - 1
Svetllana [295]

Answer:  -1/9  which is <u>choice B</u>

Explanation:

The term "zeros" refers to the x intercepts.

Plug in y = 0 and solve for x.

A deposit of $1,500 is made into a savings account which earns 4 5 /8
MAVERICK [17]

Answer:

$1880.48  to the nearest cent.

Step-by-step explanation:

Total after n years = P(1 + r)^n    where P = initial deposit, r = the rate as a fraction.

4 5/8 % = 0.04625.

Here the total after 5 years  = 1500(1 +  0.04625)^5

= $1880.48  to the nearest cent.

FOUR FRIENDS SHARE 3 SHEETS OF PAPER EQUALLY.
jenyasd209 [6]

Answer:

\frac{3}{4} of a sheet of paper

Step-by-step explanation:

Hi!

This isn't the easiest to explain with numbers but I'll do it with an example instead.

If you had 60 cookies and had to split it equally with you and one of your other friends, how would you do it?

You would do \frac{60}{2}, right? Because you have 60 cookies and you're dividing it amongst 2 people.

It's the same idea here!

We take the number of sheets of paper, and we divide it by the number of people we have to share it with.

so we do  \frac{3}{4}. You don't even have to simplify in this case because this is a fraction and this is the simplest form of this fraction as well

I hope this made sense, let me know if you have any questions

Bought a new car lately? The following table presents the number of vehicles sold in a certain country by several manufacturers
ella [17]

Answer:

The Relative Frequency Table is:

<u>  Manufacturer         Relative Frequency  </u>

General Motors                  0.242

      Ford                              0.208

Chrysler LLC                       0.148  

     Toyota                           0.177

     Honda                            0.116

     Nissan                            0.109

Step-by-step explanation:

To find out the relative frequency we need to use the formula:

Relative Frequency = Frequency / Sum of All Frequencies

We can find the sum of all the frequencies by adding all the sales for the year 2013.

Sum of Frequencies for 2013 = 225,650 + 194,068 + 138,085 + 164,423 + 107,526 + 101,113

Sum of Frequencies for 2013 = 930865 cars

Now we can compute the relative frequencies for each of the manufacturers as follows:

General Motors: 225650/930865 = 0.242

Ford: 194068/930865 = 0.208

Chrysler LLC: 138085/930865 = 0.148

Toyota: 164423/930865 = 0.177

Honda: 107526/930865 = 0.116

Nissan: 101113/930865 = 0.109

Relative Frequency Distribution Table for the 2013 sales:

Manufacturer         Relative Frequency

General Motors                  0.242

      Ford                              0.208

Chrysler LLC                       0.148  

     Toyota                           0.177

     Honda                            0.116

     Nissan                            0.109
