Step-by-step explanation:

Hi there!

[tex]\large\boxed{AB = 32.60 in}[/tex]

Find the length of AB by finding the length of its base:

We can use sine to solve for the length of the Hypotenuse of the triangle located in the base:

sin  = O / H

sin 50° = 24 / H

h * sin 50° = 24 ----> h = 24 / (sin 50°)

h ≈ 31.33 in

Use the Pythagorean Theorem to solve for the length of the diagonal since we have solved for the base of the triangle:

c² = a² + b²

c² = 31.33² + 9²

c² = 1062.57

c ≈ 32.60 in

AB = 32.60 in

Answer:

Time = 500 seconds  or 8.333 minutes

Step-by-step explanation:

Time = Distance/Speed

Speed of light = 3 x 10^8 meters/second

Distance=1.5 X 10^11 meters

Time = 1.5 X 10^11 meters/3 x 10^8 meters/second

We solve using the scientific notation. When 8 is taken to the top it is subtracted from 11 ( the base 10 is the same -- laws of exponents)

Dividing 1.5  by 3 gives 0.5 .

Time = 1.5 X 10^(11- 8) meters/3 meters/second

Time = 0.5 X 10^3 seconds

Time = 500 seconds

Dividng seconds with 60 will give minutes

Time= 500/60 = 8.333 minutes

[tex]6z + 7 = 8z - 9[/tex]

[tex]8z - 9 = 6z + 7[/tex]

Add sides 9

[tex]8z - 9 + 9 = 6z + 7 + 9[/tex]

[tex]8z = 6z + 16[/tex]

Subtract sides 6z

[tex] - 6z + 8z = - 6z + 6z + 16[/tex]

[tex]2z = 16[/tex]

Divide sides by 2

[tex] \frac{2z}{2} = \frac{16}{2} \\ [/tex]

[tex]z = 8[/tex]

Thus ;

[tex]NP = 8z - 9[/tex]

[tex]NP = 8(8) - 9[/tex]

[tex]NP = 64 - 9[/tex]

[tex]NP = 64 - 4 - 5[/tex]

[tex]NP = 60 - 5[/tex]

[tex]NP = 55[/tex]

Done...

Answer:

x=4

Step-by-step explanation:

Answer:

m<ACD = 90

m<CDB = 126

m<EDB = 54

m<CDE = 180

Step-by-step explanation:

Well you have the right girl! *In honors geometry you can trust me!

Ok first thing...We already know

B = 54

A = 90  

D = 54 (It's the Alternate interior angle of B)

C = 90

m<ACD = 90 (C = 90)

m<CDB = 126 (D = 54 ------> 180-54= 126)

m<EDB = 54 (Alternate Interior angle of B)

m<CDE = 180 (It is a straight line)

Answer:

49.5 meters of linen were left after the sale.

Step-by-step explanation:

Given that there are 100 meters of linen

And 15.75, 22.50 and 12.25 meters are sold.

This means that the sold linen has to be added  to find the total linen sold.

And then the quantity of sold linen will be subtracted from 100 to find the meters of linen left.

[tex]Total\ linen\ sold = 15.75+22.50+12.25 = 50.5\ meters[/tex]

Left linen will be:

[tex]=100-50.5 = 49.5[/tex]

Hence,

49.5 meters of linen were left after the sale.

9514 1404 393

Answer:

Step-by-step explanation:

The square of a binomial is ...

  (x +a)² = x² +2ax + a²

Comparing this to your expression, we have ...

  2a = 20 . . . . x-coefficient

  a² = c . . . . . . constant term

Then ...

  a = 20/2 = 10

  a² = 10² = 100 = c

The square is then ...

  (x +10)²

Answer:

c = 100 makes this a perfect square trinomial

Step-by-step explanation:

[tex]x^2+20x+c\\x^2+20x+100\\=(x+10)^{2}[/tex]

Answer: It´s 6.

Step-by-step explanation:

Answer:

y = 8x + 38

Step-by-step explanation:

To find the slope we set up y = mx + b and plug m (our slope) in and then plug in the point into x and y to find b (our y-intercept)

   y = mx + b

   y = 8x + b

   6 = 8(-4) + b

   6 = -32 + b

+32   +32

 38 = b

So using our slope and our intercept we have our slope intercept

y = mx + b

y = 8x + 38

Hope this helps :)

Answer:

y - y1 = m(x - x1)

y - 6 = 8(x - (-4))

y - 6 = 8(x + 4)

y - 6 = 8x + 32

y = 8x + 32 + 6

y = 8x + 38

Step-by-step explanation:

First you input the given values ( m = 8 and (-4, 6)) into the point-slope equation.

After that, you multiply the 8 by the two terms inside the parentheses, giving you 8x and 32.

Then you add 6 to both sides of the equation to isolate the y.

The slope-intercept equation ends up looking like this: y = 8x + 38

Hope this helps :)

Answer:

The answer is 166

Step-by-step explanation:

How you find the answer is easy, you just divide 3,000 by 18. So it will look like this: 3,000/18. Then, once you have that, put the equation into a calculator and you get 166.

The number of liters in a day is 4 liters.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 3000 milliliters in 18 hours.

Here, in 1 hour number of milliliters

= 3000/18

= 166.7

We know that, 1 day = 24 hours

So, the number of milliliters in 24 hours is

166.7×24

= 4000.8 milliliters

As we know that, 1 liter = 1000 milliliters

Now, 4000.8 milliliters = 4000.8/1000

= 4.0008 liters

≈ 4 liters

Therefore, the number of liters in a day is 4 liters.

Step-by-step explanation:

You have to divide 5 1/2 into groups of 1/2. 5 1/2÷1/2=11.

Answer:

there are two variables x and y which variable do u need to find or do u need it in point slope form

Answer:

Simplifying

6x + 3y = 54

Solving

6x + 3y = 54

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

6x + 3y + -3y = 54 + -3y

Combine like terms: 3y + -3y = 0

6x + 0 = 54 + -3y

6x = 54 + -3y

Divide each side by '6'.

x = 9 + -0.5y

Simplifying

x = 9 + -0.5y

Answer: Sure,

Step-by-step explanation:

The form ax^2 + bx + c = 0 is called standard form of a quadratic equation. Before solving a quadratic equation using the Quadratic Formula, it's vital that you be sure the equation is in this form. If you don't, you might use the wrong values for a, b, or c, and then the formula will give incorrect solutions.

Answer: That is standard form.

Answer:

7500 N

Step-by-step explanation:

Given that,

A hammer claw moves a distance of 0.10 meters to remove a nail.

Resistance force, F = 1500 N

The person move the handle of the hammer 0.5 m

We need to find the effort force. Let it is F'. The mechanical advantage is given by :

[tex]m=\dfrac{effort}{resistance}=\dfrac{d_i}{d_o}[/tex]

Where [tex]d_i\ \text{and}\ d_o[/tex] are input and output distance respectively.

[tex]m=\dfrac{F'}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=0.2\\\\F=7500\ N[/tex]

So, the effort force is 7500 N.
