Answer 1

Answer:

x = (8.75 - 2 5/6) / 7.1 + (4 1/2 + 2 2/3) / 4 3/10

x = 2.5

Answer 2

Answer:

2  1/2

Step-by-step explanation:

Order of operations rules require that we do any work within parentheses first.  Thus, calculate (8.75 - 2  5/6); it is (5  11/12).  Next, calculate (4  1/2 + 2  2/3); it is ( 7  1/6).  So what we have now looks like:

(5  11/12) / 7.1  + (7  1/6) / (43/10)    (Note that 4  3/10 = 43/10)

Performing the two indicated divisions, we get:

5/6 + 1  2/3.

Since the LCD here is 6, we add:    5/6 + 1  4/6, which comes out to

                                                          1  9/6, or 1 + 1  1/2, or    2  1/2 (answer)

a ticket office sold 553 tickets one day. the receipts totaled $3936. how many $9 adult tickets and how many $6 child tickets were sold​

Answers

This is the assumption method ;)

Take all tickets to be adult tickets

$9 x 553 = $4977

Then..... $4977 - $3936 = $1041

The difference between the child and adult ticket is $3, so divide $1041 by $3

$1041 divided by $3 = 347

347 is the number of child tickets sold

347 x $6 = $2082

So 553 - 347 = 206 ( no. of adult tickets )

206 x $9 = $1854

Child tickets sold : 347

Adult tickets sold : 206

:0 ITS MAGIC IM SO SMART

Answer:

347 child tickets and 206 adult tickets are sold

Step-by-step explanation:

Let x be the no. of child tickets sold

Let y be the no. of adult tickets sold

A ticket office sold 553 tickets one day.

Equation becomes : [tex]x+y=553[/tex] ---A

Cost of 1 child ticket = $6

Cost of x child tickets = 6x

Cost of 1 adult ticket= $9

Cost of y adult tickets = 9y

Now we are given that the receipts totaled $3936.

So, Equation becomes : [tex]6x+9y=3936[/tex] ---B

Plot A and B

[tex]x+y=553[/tex] ---Green

[tex]6x+9y=3936[/tex] ---Purple

Intersection point = (x,y)=(347,206)

Refer the attached figure

Hence 347 child tickets and 206 adult tickets are sold

Answers

Answer:

O.118 seconds will be taken for a radio signal to travel from a satellite to the surface of earth.

Step-by-step explanation:

We are given Speed = 3.00 · 10^8 meters per second.

And Distance = 3.54.10^7 metwers

We need to find time.

We know that,

Distance = Speed * Time

3.54.10^7 = 3.00 · 10^8 * Time

Time = 3.54.10^7 / 3.00 · 10^8

Time = 1.18 X 10^7-8

Time = 1.18 x 10^-1

Time = 0.118 seconds.

So, O.118 seconds will be taken for a radio signal to travel from a satellite to the surface of earth.

Abc is a rectangle find m angle AEB

Answers

Check the picture below.

Answer:

The correct answer is last option.

m<AEB = 140

Step-by-step explanation:

From the figure we can see  rectangle.

It is given that, m<ADE = 70°

To find the value of m<AEB

From the figure we get Triangle ADE is isosceles triangle

<DAE = 70°

Therefore m<AED = 180 - (70 + 70) = 40°

<AED and <AEB  are linear pairs

Therefore m<AEB = 180 - m<AED

 = 180 - 40 = 140

The correct answer is last option

what is the center of the circle given by the equation x^2+y^2-14y-15=0

Answers

Answer:

(0, 7)

Step-by-step explanation:

The equation of a circle in the standard form:

[tex](a-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

We have the equation:

[tex]x^2+y^2-12y-15=0[/tex]

Convert into a standard form using

[tex](a-b)^2=a^2-2ab+b^2\qquad(*)[/tex]

[tex]x^2+\underbrace{y^2-2(y)(7)+7^2}_{(*)}-7^2-15=0\\\\(x-0)^2+(y-7)^2-49-15=0[/tex]

[tex](x-0)^2+(y-7)^2-64=0[/tex]           add 64 to both sides

Answers

Answer:

y=-4x-17

Step-by-step explanation:

You want to find the equation for a line that has a slope of -4 and a y-intercept of -17.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

All you really have to do here is

replace m with -4, which is the slope you gave, and

replace b with -17, the y-intercept you gave,

in the equation y=mx+b.

The equation of the line that has a slope of -4 and a y-intercept of -17 is:

y=-4x-17.

Answer:

[tex]x = 230/3\\[/tex]

Step-by-step explanation:

Step 1:  Distribute

12x + 110 = 6(x + 100)

12x + 110 = (6 * x) + (6 * 100)

12x + 110 = 6x + 600

Step 2:  Subtract 6x from both sides

12x + 110 - 6x = 6x + 600 - 6x

6x + 110 = 600

Step 3:  Subtract 110 from both sides

6x + 110 - 110 = 600 - 110

[tex]6x = 490[/tex]

Step 4:  Divide both sides by 6

[tex]6x / 6 = 490 / 6[/tex]

[tex]x = 490 / 6[/tex]

Which function is positive for the entire interval [-3, -2]

Answers

Answer:

Graph B

Step-by-step explanation:

We are given 4 graphs.

We need to find the function graph which is positive of the entire interval [-3, -2]

It is a closed interval. So it is inclusive of -3 and -2

In these interval the graph of y value must be in positive region.

By looking at the graph, the graph B has positive y-values in the entire interval [-3, -2]

Therefore, the answer is Graph B)

Answer:

Graph 2 represents that the  function is positive for the entire interval [-3, -2].                      

Step-by-step explanation:

We are given four different graphs for different functions. We have to find the graph that is positive for the entire interval [-3,-2].

We make the following observation from the given graphs.

In graph 1, the function has a value of 0 at -3 and and the value decreases from -3 to -2. Thus, the function is negative in the given interval.In graph 2, it can be clearly seen that the function has a positive value, through the entire given interval.In graph 3, the function shows negative value entirely in the given interval.In graph 4, the function exhibits both positive and negative value in the given interval and in not positive in the entire interval.

Thus, function in graph 2 is positive for the entire interval [-3, -2].

elimination/subtraction
3x - 10y=-70
4x +9y = 63

(can you please explain in step by step?)​

Answers

Answer:

x = 0, y = 7

Step-by-step explanation:

Solving a system of equations using substitution requires one side to be equal to a variable present in the equation, in this case x or y. We should simplify the equation using elimination before substituting to reduce the chance of error.

In order to use the elimination method, you have to create variables that have the same coefficient—then you can eliminate them. These equations arew already aligned for us.

                  3x - 10y=-70

             -   4x +9y = 63

                  -x + y = 7

Now, for substitution, the equation must be set to a variable.

                  -x + y = 7

                  y = x + 7

Next, plug the equation in where applicable in another equation.

                  4x +9(x + 7) = 63

                  4x + 9x + 63 = 63

                  13x = 0

                  x = 0

The final step of substitution is to plug the known variable into an equation to find the other variable.

                  3(0) - 10y=-70

                  0 - 10y = -70

                  10y = 70

                  y = 7

I guarantee you this answer is correct, I worked it out using other methods and graphing prior to submitting this answer.

Answer:

x = 0 , y = 7

Step-by-step explanation:

[tex]3x - 10y = - 70..............(1) \\ 4x + 9y = 63...................(2) \\ (1) \times 4 \\ 12x - 40y = - 280...........(3) \\ (2) \times 3 \\ 12x + 27y = 189...........(4) \\ (4) - (3) \\ 67y = 469 \\ \\ y = \frac{469}{67} \\ y = 7 \\ put \: y = 7 \: into \: (1) \\ 3x - 10(7) = - 70 \\ 3x - 70 = - 70 \\ 3x = - 70 + 70 \\ 3x = 0 \\ x = \frac{0}{3} \\ x = 0[/tex]

Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic to penicillin, Nathan had a 75% chance of having the same allergy. The doctor performed a skin test to see whether Nathan would react to it. The test is 98% accurate. What is the probability that Nathan is allergic to penicillin and the test predicts it?

Answers

Answer:

[tex]P=0.735[/tex]

Step-by-step explanation:

Call A to the event in which Nathan is allergic to penicillin

So

[tex]P (A) = 0.75[/tex]

[tex]P (A') = 1-P (A) = 0.25[/tex]

Call B the event in which the skin test predicts correctly.

So:

[tex]P (B) = 0.98\\P (B ') = 1-P (B) = 0.02[/tex]

We look for the probability that Nathan is allergic to penicillin and the test predicts it.

This is [tex]P (A\ and\ B)[/tex].

[tex]P (A\ and\ B) = P (A)*P (B)\\\\P (A\ and\ B) = 0.75 * 0.98\\\\P (A\ and\ B) = 0.735[/tex]
