whats is the prouduct for 4/5 3/7​

Answer:

Step-by-step explanation:

Perimeter

P = 4s

P = 4*(2*sqrt(3) + 6*sqrt(7) )

P = 8*sqrt(3) + 24*sqrt(7)

Area

A = s^2

A = (2sqrt(3) + 6sqrt(7) )(2 sqrt(3) + 6sqrt(7) )

F:= (4*sqrt(3)^2 = 16 * 3 = 48

O:= 2sqrt(3) * 6sqrt(7) ) = 12sqrt(21)

I := 6*sqrt(7)*2 sqrt(3) = 12 sqrt(21)

L:=6*sqrt(7) ^2 = 36 * 7 = 252

The answer is 300 + 24*sqrt(21)

Answer:

Step-by-step explanation:

area=side ²=(2√3+6√7)²=4×3+36×7+2×2√3×6√7=12+252+24√21=264+24√21

2) 3.833

3) 4

4) 9.866

Answer:

Isosceles, obtuse triangle

Step-by-step explanation:

The triangle is isosceles since there are equal acute-angles which therefore prove two equal sides.

The triangle is obtuse because it consists of one obtuse angle which is 98 and is greater than 90 degrees.

it will take 8 minutes

Step-by-step explanation:

Here, we want to

calculate the amount of time taken to fill the tank given the total amount of water in the tank.

Mathematically, the formula go

use is ;

w= 100 + 55t

540 = 100 + 55t

55t = 540-100

55t = 440

t = 440/55

t = 8

Answer:

-3

Step-by-step explanation:

We need to use the distributive property a couple times to expand the parentheses.

Remember that when expanding parentheses, we find the sum of the products of the outside term with each of the inside terms.

5(x - 4) = 5 * x + 5 * (-4) = 5x - 20

-(2x + 5) = -1 * 2x + -1 * 5 = -2x - 5

Now we have:

5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x

Combine all the terms with x:

-x - 20 = 6x + 1

7x = -21

Divide by 7:

x = -21/7 = -3

The answer is thus -3.

Answer:

7020

Step-by-step explanation:

The letter could be any 1 of the 26 and it could be placed in any 1 of 3 places so this makes 26*3 = 78 possibilities.

For each of these  there is any one of  permutations of 2 digits from 10

= 10P2 = 10! / 8! = 10*9 = 90.

So the answer is 78 * 90 =  7020.

Note I am assuming that the 2 digits picked are different - no duplicates.

Answer:  tan(14x)

Step-by-step explanation:

Consider the Sum Formula for tan:

[tex]tan(A + B)=\dfrac{tan(A)+tan(B)}{1-tan(A)(tan(B)}\\\\\\tan(9x+5x)=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}\\\\\\\large\boxed{tan(14x)}=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}[/tex]

Answer:

[tex]\tan(4x)[/tex]

Step-by-Step Explanation:

Notice that this resembles the difference identity for tangent. Specifically:

[tex]\displaystyle \tan(\alpha-\beta)=\frac{\tan(\alpha)-\tan(\beta)}{1+\tan(\alpha)\tan(\beta)}[/tex]

So, given our equation, we can pretend that α=9x and β=5x. Therefore:

[tex]\displaystyle \frac{\tan(9x)-\tan(5x)}{1+\tan(9x)\tan(5x)}=\tan(9x-5x)=\tan(4x)[/tex]

Step-by-step explanation:

Answer:

y = - 4x + 17

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, 1) and (x₂, y₂ ) = (2, 9)

m = [tex]\frac{9-1}{2-4}[/tex] = [tex]\frac{8}{-2}[/tex] = - 4, thus

y = - 4x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 1) , then

1 = - 16 + c ⇒ c = 1 + 16 = 17

y = - 4x + 17 ← equation of line

Answer

It is B because Q rotate with 180 degree so if it rotates again with 180 degree it ends on point B

Step-by-step explanation:

Answer:

Point B

Step-by-step explanation:

A 180 degree turn means that the point practically reflects over the y-axis.  The number of spaces away from (0,0) that Point Q was originally is the number of spaces that Point Q will still be from (0,0).  Point Q, like already said, will just be on the other side of the y-axis.  Point Q's original coordinates were (0,-4), which means that point Q was originally 4 units away from (0,0) on the x-axis on the left side of the y-axis.  That means with a 180 degree transformation, Point Q will be still 4 units away from (0,0) on the x-axis, but on the right side of the y-axis.  The new coordinate pair for Point Q would be (0,4), which is also where Point B is plotted on the graph.  Therefore, Point B would be the new image of Point Q.

The box on the truck has dimensions 11 ft by 7 ft by 4 ft.

The volume of the box is:

V = L * W * H

V = 11 * 7 * 4

V = 308 cubic feet

The truck can transport 308 cubic feet of gravel.

Answer:

Step-by-step explanation:

5 x + 2 = 7 x − 4

7x-5x= 2+4

2x= 6

x= 3

Answer:

The value of x in this equation is 3.

Step-by-step explanation:

5x + 2 = 7x - 4

Subtract 7x from both sides of the equation.

-2x + 2 = -4

Subtract 2 from both sides of the equation.

-2x = -6

Divide by -2 on both sides of the equation.

Answer:

  4.  F(x) = (x -8)^2 -6

Step-by-step explanation:

The function ...

  f(x) = (x -h)^2 +k

shifts the parent function h units to the right and k units up. Here, the parent function is shifted right and down, so h > 0, k < 0. This matches choice 4.

  F(x) = (x -8)^2 -6

The function which represents the graph on the coordinate plane is

y = (x-8)² - 6.

The option 4 is the correct option.

Transformation of a function is shifting the function from its original place in the graph.

Types of transformation-

Horizontal shift- Let the parent function is f(x). Thus, by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.

Vertical shift- Let the parent function is f(x). Thus, by replacing parent function with f(x) - c shifts the graph c units down and by replacing parent function with f(x) + c shifts the graph c units up.

Given-

In the given problem the parabola is shown which shifted horizontally and vertically from the origin.

The vertex form of the parabola can be given as,

y = a(x-h)² - k

Here, (h, k) is the vertex of the equation.

As the graph is shifted right horizontally with some unit (8) from the option and shifted down vertically with some unit (6) from the option. Thus, the equation can be written as,

y = (x-8)² - 6

Hence function which represents the graph on the coordinate plane is,

y = (x-8)² - 6

Answer:

The expression represents Ann's membership cost as a function of how many times she brings John along. For t = 5 the cost is 275, for t = 10, the cost is 250 and for t = 20 the cost is 200.

Step-by-step explanation:

The expression "300 - 5*t" represents the cost of Ann's membership plan on the local gym, where "t" is the number of visits John pays Ann. This means that the more times John goes to the gym with Ann, the less is her cost to pay the membership.

For t = 5:

[tex]cost = 300 - 5*t\\cost = 300 - 5*5 = 275[/tex]

For t = 10:

[tex]cost = 300 - 5*t\\cost = 300 - 5*10 = 250[/tex]

For t = 20:

[tex]cost = 300 - 5*t\\cost = 300 - 5*20 = 200[/tex]

Answer:

B

Step-by-step explanation:

The soccer player has g goals and a assists.

For every goal, he/she gets 2 points and for every assist, he/she earns 1 point. This means that if we multiply g by 2, we get the number of points the player receives from g goals and if we multiply a by 1, we get the number of points the player receives from a assists.

And, that total number of points is equal to 42, so we can write:

2 * g + 1 * a = 42

2g + a = 42

Now, we understand that g and a are the number of goals and assists the player has made, and we also know that the total number of such kicks is 24, so we can write:

g + a = 24

Thus, our system is:

g + a = 24

2g + a = 42

The answer is B.

Answer:

The correct answer is B. g + a = 24. 2 g + a = 42

Answer:

18.75%

Step-by-step explanation:

Hello,

3 students are both female and senior

the total number of students is 7+10+8+5=30

so the probability to select one female senior is 3/30=1/10=0.10

probability to select one female is 16/30=16/30

probability that the student is a senior given that it's female is

=P(female and senior)/P(female)

=1/10*30/16=3/16

hope this helps

Answer:

19%

Step-by-step explanation:

Find the number of female students

3+4+6+3 = 16

P( senior given that it is female = senior/ female

                                                    = 3/16

                                                      =.1875

                                                       18.75%
