Answer 1

Step-by-step explanation:

Put the what given of y in equation 2 to equation of 1

So you get

[tex] \frac{4}{5} x + \frac{2}{5} x - 7 = - 4 \\ \frac{6}{5} x = 3 \\ x = \frac{15}{6 } \\ x = \frac{5}{2} [/tex]

Then put the value of x in second equation

You will get

[tex]y = - \frac{2}{5} \times \frac{5 }{2} + 7 \\ \\ y = 6[/tex]

Christian is planning a vacation and finds an airplane ticket that cost 180$. He found a promo code offering 17% off. Write a single algebraic expression that can be used to find the cost of Christian’s ticket after the discount.

Answers

Answer:

83/100 x 180

Step-by-step explanation:

We have to find the cost of the ticket after the discount.

100% - 17%= 83%

83% of the total percentage of the original price that he needs to pay.

So we do:

83/100 x 180

So, this would be the expression.

Company cuz closed at $52.93 per share with a P/E ratio of 15.17 how much were earnings per share

Answers

Answer: $3.49

Step-by-step explanation:

Earnings per share shows how much of the profit of the company every share will get.

You can use it to calcutae the P/E ratio through the following formula:

P/E ratio = Share price / Earnings per share

15.17 = 52.93 / EPS

EPS * 15.17 = 52.93

EPS = 52.93 / 15.17

= $3.49

If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?

Answers

Answer:

$36.38

Step-by-step explanation:

If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?

Given data

Tax= 7%

Cost = $34

Let us solve for the amount of tax

=7/100*34

=0.07*34

=2.38

Hence the total is =2.38+34

=$36.38

5.what number should be included in the data 2,8,7,4 and 9 so that the mean is 6 ​

Answers

Answer:

0

Step-by-step explanation:

find mean of given numbers u notice that mean is actually 6 so no number is required to be included

Answer:

4. x = 35. Number 6 should be included

Step-by-step explanation:

Mean is the average

4.

Data given:

14, 6, 2x, 8, 10, 4

The mean is

mean = sum of the data / number of data(14 + 6 + 2x + 8 + 10 + 4)/6 = 842 + 2x = 6*82x = 48 - 422x = 6x = 3

5. Let the added number is x, then the mean is:

(2 + 8 + 7 + 4 + 9 + x)/ 6 = 6x + 30 = 36x = 36 - 30x = 6

204

Step-by-step explanation:

The area of the top triangle = 5*12/2 =                        30

The area of the bottom triangle =                                30

The hypotenuse of the top triangle is

5^2 + 12^2 = hypotenuse^2

25 + 144 = hypotenuse^2

169 = hypotenuse squared.

hypotenuse = sqrt(169)

hypotenuse = 13

Now the back face = 13 * 8 =                                       104

The area of the left side rectangular  face = 5*8 =     40

The total area = 30 + 30 + 104 + 40 =                        204

the total no of population=1650

13:17 first add the two numbers 13+17=30

then 13/30×y =715 , i make 13 at the numerator because it's males ratio

after that 30/13×13/30y =715 ×30/13

y =715×30/13

y =1650

after u find the total no it's simple to find the no of females

17/30×1650=935

Find the area of equilateral triangle with side a. Please answer with completely simplified exact values. Answer: A = sq. Units

Answers

Solution :

It is given that the length of a side of a triangle is given by 'a'.

It is an equilateral triangle.

So the three sides will be of equal length and is a, a, a units.

Now the semi perimeter of the equilateral triangle is given by :

[tex]$S=\frac{a+a+a}{2}$[/tex]

  [tex]$=\frac{3}{2}a$[/tex]

Therefore, using the Heron's formula, we can find the area of the equilateral triangle.

Area of the equilateral triangle is given by :

[tex]$A =\sqrt{S(S-a)(S-a)(S-a)}$[/tex]

[tex]$A =\sqrt{\frac{3a}{2}\left(\frac{3a}{2}-a\right)\left(\frac{3a}{2}-a\right)\left(\frac{3a}{2}-a\right)}$[/tex]

[tex]$A=\frac{\sqrt3}{4}a^2$[/tex] square units.
