Simplify 7(3x = y) i need help im to confused

Answer:

I think you meant 4/20 but thats 20%

Step-by-step explanation:

U don't have to put this on the calculator because 20 to be 100 you have to multiply it by 5. So 4 times 5 is 20 so its 20% hope I helped :DD

Answer:

20%

Step-by-step explanation:

4/20 can be tuned into a easier fraction that has 100 as a denominator.

So, 20*5=100 and 4*5=20 = 20/100

So the numerator is 20 meaning 20%

Answer:

$4783.33

Step-by-step explanation:

lets convert the dimensions from ft to yards

41 ft = 13 2/3 yards

42 ft = = 14 yards

Lets multiply:

(first I am going to convert 13 2/3 to an improper fraction : 41/3)

41/3 x 14/1 = 574/3  = 191 1/3 sq yards

Lets multiply that by 25 because it is $25 / sq yrd

4775 + 8 1/3 =  = $4783 1/3 = $4783.33

Answer:

14 x 15 x 18 + 11 x 13 x 16

Step-by-step explanation:

Answer:

An expression is:

14×15×18+11×13×16 is a required answer.

Answer:

x = 7.5, y = 134

Step-by-step explanation:

Since both polygons are similar, hence the ratio of their similar sides will be equal to a constant;

Using the similarity theorem;

6/4 = x/5

4x = 6 * 5

4x = 30

x = 30/4

x = 7.5

Also;

y - 73 = 61

y = 73+61

y = 134

Hence x = 7.5, y = 134

Answer:

Step-by-step explanation:

Part 1

There are many ways to go about this, but one possibility is the following:

You are building a tree house. Your ladder is 10 feet long and the portion in the tree you're trying to get to is 8 feet off the ground. How far should the base of the ladder be from the tree so you can reach that portion?

==========================================================

Part 2

The drawing is shown below. The diagram is shown in 2D to keep things as simple as possible. Adding a third dimension greatly complicates everything.

We have a right triangle, so it has a 90 degree angle as shown by the square marker. The vertical leg is 8 feet. The horizontal leg is unknown. The hypotenuse (longest side) is 10 feet long to indicate the ladder.

==========================================================

Part 3

Use the pythagorean theorem to get...

a^2 + b^2 = c^2

x^2 + 8^2 = 10^2

x^2 + 64 = 100

x^2 = 100-64

x^2 = 36

x = sqrt(36)

x = 6

The base of the ladder should be 6 feet away from the tree, so that you can reach 8 feet off the ground.

Answer:

C and D

Step-by-step explanation:

4x^2-49/64=0

4x^2=49/64

x^2=12.25/64

x=sqrt(12.25/64)

x=7/16 and x=-7/16

Answer:

Y = 15x + 30 and 8 hours

Step-by-step explanation:

She gets $15 per hour so her income is based on her hours, but we don't know what that is yet so, 15x.

She gets a solid $30 every week that is straight forward

To solve the function

150 = 15x + 30

subtract 30 from both sides

120 = 15x

divide 15 from both sides

8 = x

or

x = 8

You got this :)

Answer:

1. The answer would be A, Adjacent and supplementary

2.  The answer would be A supplementary.

Step-by-step explanation:

Supplementary angles add up to 180 degrees, both of the questions have angles that add up to 180 degrees. Adjacent mean that that the angle are next to each other in intersecting lines.

Answer:

20:18 30:27 40:36 etc..

To find equivalent ratios you multiply both 10 and 9 by the same number to find equivalent ratios.

Answer:

I would go with letter B. -7

Step-by-step explanation:

The two factors of a quadratic equation can be multiplied to form the original equation. Let the missing term be a:

y² + 15y + 56 = (y + 7)(y + a)

y² + 15y + 56 = y² + (7 + a)y + 7a

Step by step solution :

STEP  1 :

Trying to factor by splitting the middle term

1.1     Factoring  y2+14y+49  

The first term is,  y2  its coefficient is  1 .

The middle term is,  +14y  its coefficient is  14 .

The last term, "the constant", is  +49  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 49 = 49  

Step-2 : Find two factors of  49  whose sum equals the coefficient of the middle term, which is   14 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  7  and  7  

                    y2 + 7y + 7y + 49

Step-4 : Add up the first 2 terms, pulling out like factors :

                   y • (y+7)

             Add up the last 2 terms, pulling out common factors :

                   7 • (y+7)

Step-5 : Add up the four terms of step 4 :

                   (y+7)  •  (y+7)

The solution is:

  y  =  -7  

 The solution is:

 y = -14 / 2 = -7

Step-by-step explanation:

The answer is 6

The number of points are:

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area.

Circumference (or) perimeter of circle = 2πR

A Ferris wheel has a radius of 50 feet, and its center is 60 feet off the ground.

So, DA = r = 50 feet

OB = 30 feet

<AOC = 2 <AOB

          = 2 x arc sin (4/5)

and, Circumference = 2πr = 100π

Then, AC = (2π - 2 arc sin (4/5)) . 50

Let there are total p points

So, A= (1- arcsin (4/5)/π )p

Thus, 2 points for 30 feet off the ground.

and, 1 points for 110 feet off the ground.

and, 0 points for 5 feet off the ground.

Answer:

Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole.

Step-by-step explanation:

Using the Pythagorean Theorem, ([tex]a^2+b^2=c^2[/tex] ) we can measure the hypotenuse of a right triangle. Since the doorway is a rectangle, and a rectangle cut diagonally is a right triangle, we can use Pythagorean Theorem to measure the diagonal width of the doorway.

Plug in the values of the length and width of the door for a and b. The c value will represent the diagonal width of the doorway:

[tex]6^2+9^2=c^2[/tex]

[tex]36+81=c^2[/tex]

[tex]117=c^2[/tex]

Since 117 is equal to the value of c multiplied by c, we must find the square root of 117 to find the value of c.

[tex]\sqrt{117} =10.8[/tex]

[tex]10.8=c[/tex]

Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole, measuring 10 feet.

Answer:

4 feet per second

Step-by-step explanation:

Hi there!

[tex]v=D/t[/tex] where v is velocity (speed), D is distance and t is time

Plug in the known values (D=180 feet, t=45 seconds)

[tex]v=180/45\\v=4[/tex]

Therefore, the speed of the ball is 4 feet per second.

I hope this helps!

Answer:
