PLEASE I REALLY NEED YOUR HELP!

Answer:

x = 6

Step-by-step explanation:

AC = 5x - 24

AO = 3

AC and BD bisect each other at point O. This means AC ≅ CO.

So, 2(AO) = AC.

2(3) = 5x - 24

Multiply.

6 = 5x - 24

Combine the constants.

30 = 5x

Divide by 5.

x = 6

Answer:

-1 < -1.5

Step-by-step explanation:

when using negative numbers, larger numbers will be smaller. so even tho 1.5 seems to be .5 bigger, it is negative, so it is .5 smaller

Answer:

x= 33.9

Step-by-step explanation:

use cosine because x is the adjacent and 40 is the hypotenuse

set up your equation:

cos(32)= (x/40)

multiply both sides by 40:

40(cos(32))= (x/40)40

40(cos(32))= x

multiply 40 by the cos(32):

33.9 = x

Answer:

You can also work on the ways that you write polynomials. One way to write a polynomial is in standard form. In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to right.

Step-by-step explanation:

Write the expression 3x−8+4x5 in standard form.

First, look at the degrees for each term in the expression.

3x has a degree of 1

8 has a degree of 0

4x5 has a degree of 5

Next, write this trinomial in order by degree, highest to lowest

4x5+3x−8

The answer is 4x5+3x−8.

The degree of a polynomial is the same as the degree of the highest term, so this expression is called a fifth degree trinomial.

Inequality

Step-by-step explanation:

There are an infinite number of quantities less than 6 (5, 4, 3, 2, 1, 0, -1, -2, -3...) so it is much easier to write an inequality

i am pretty sure im right. if im wrong im sorry

Answer:

Step-by-step explanation:

21x + 7y = 42

-5x + 5y = 10

105x + 35y = 210

  -35x - 35y = -70

70x = 140

x = 2

-10 + 5y = 10

5y = 20

y = 4

Answer:

19 minutes

Step-by-step explanation:

Taking the sea level as the reference point, the values of depths to be considered can be determined as follows;

Total depth from sea level to the sea floor = 104 feet

Katy's depth from the sea level (depth covered) = 28 feet

Katy's distance to the sea floor = 104 - 28

                                          = 76 feet

Katy's distance to the sea floor = 76 feet

But Katy moves at a rate/ speed of 4 feet per minute;

So that,

speed = [tex]\frac{distance}{time}[/tex]

time = [tex]\frac{distance }{speed}[/tex]

       = [tex]\frac{76}{4}[/tex]

       = 19

time = 19 minutes

Therefore it would take Katy 19 minutes to reach the sea floor.

Answer:

Step-by-step explanation:

No, Colin is not correct. He needs to subtract first to get the total distance and then divide by the rate. He should have put parentheses around 104–28 and then divided by 4 to get the answer of 19 minutes.

Answer:

The height of her friend is 4.826 feet.

Step-by-step explanation:

The length of the shadow ([tex]x_{S}[/tex]), measured in feet, is directly proportional to the height of the person ([tex]x_{P}[/tex]), measured in feet. That is:

[tex]x_{P} \propto x_{S}[/tex]

[tex]x_{P} = k\cdot x_{S}[/tex] (1)

Where [tex]k[/tex] is the proportionality constant, no unit.

We can eliminate this constant by constructing this relationship:

[tex]\frac{x_{P,M}}{x_{S,M}} = \frac{x_{P,F}}{x_{S,F}}[/tex] (2)

Where M and F represents Melody and Melody's friend. If we know that [tex]x_{P,M} = 5\,ft[/tex], [tex]x_{S,M} = 7\,ft[/tex] and [tex]x_{S,F} = 6\,ft[/tex], then the height of his friend is:

[tex]x_{P,F} = \left(\frac{x_{P,M}}{x_{S,M}} \right)\cdot x_{S,F}[/tex]

[tex]x_{P,F} = \left(\frac{5\,ft}{7\,ft}\right)\cdot (6\,ft)[/tex]

[tex]x_{P,F} = 4.286\,ft[/tex]

The height of her friend is 4.826 feet.

Answer:

The distance is 280 miles

Step-by-step explanation:

Given

When going to the mountain:

Let the speed be x.

[tex]Speed = x[/tex]

[tex]Time = 8[/tex]

When going home:

[tex]Speed = 21 + x[/tex]

[tex]Time = 5[/tex]

Required

Determine the distance of the mountains

Distance is calculated as:

[tex]Distance = Speed * Time[/tex]

When going to the mountains, the distance is:

[tex]Distance = x * 8[/tex]

When going home, the distance is:

[tex]Distance = (21 + x) * 5[/tex]

It should be noted that, the distance is the same.

So, we have:

[tex]x * 8 = (21 + x) * 5[/tex]

Open bracket

[tex]x * 8 = 21* 5 + x * 5[/tex]

[tex]8x = 105 + 5x[/tex]

Collect Like Terms

[tex]8x - 5x= 105[/tex]

[tex]3x= 105[/tex]

Divide both sides by 3

[tex]x= \frac{105}{3}[/tex]

[tex]x= 35[/tex]

Substitute 35 for x in

[tex]Distance = x * 8[/tex]

[tex]Distance = 35 * 8[/tex]

[tex]Distance = 280[/tex]

The distance is 280 miles

Answer:

The population of Hawks and other species would likely start to edge off.

Step-by-step explanation:

Commonly, a Food Chain is dependent on all the parts of it sataying at a perfect point. If the food that the Snakes eat starts to run out, more of them will die off. With less Snakes, the Hawks will then have less food, and that continues throughout the chain. The same thing would happen if there was too much food, except instead of the populations of species dying off, the Snake population would spike.

Answer:

Sarah is watching a video online that is 4.7 minutes long.

Step-by-step explanation:

As we know 60 sec = 1 minute

⇒60×4 sec = 1×4 minutes

⇒240 sec = 4 minutes

⇒246.987 ≈ 247

                  = 240 + 7 seconds

                  = 4 minutes 7 seconds

                  = 4.7 minutes

∴ we get

Sarah is watching a video online that is 4.7 minutes long.

Answer:

[tex]\stackrel{\large{\frown}}{ADC} = 186^{\circ}[/tex]

Step-by-step explanation:

Given

See attachment

Required

Determine the measure of [tex]\stackrel{\large{\frown}}{ADC}[/tex]

[tex]The\ sum\ of\ angles\ in\ a\ circle\ is[/tex] [tex]360^{\circ}[/tex].

So, we have:

[tex]\stackrel{\large{\frown}}{ADC} + \stackrel{\large{\frown}}{APB} + \stackrel{\large{\frown}}{BPC} = 360^{\circ}[/tex]

Where:

[tex]\stackrel{\large{\frown}}{APB} = 70^{\circ}[/tex]

[tex]\stackrel{\large{\frown}}{BPC} = 104^{\circ}[/tex]

Substitute these values in the above equation.

[tex]\stackrel{\large{\frown}}{ADC} + 70^{\circ} +104^{\circ} = 360^{\circ}[/tex]

[tex]\stackrel{\large{\frown}}{ADC} + 174^{\circ} = 360^{\circ}[/tex]

Collect Like Terms:

[tex]\stackrel{\large{\frown}}{ADC} = 360^{\circ} - 174^{\circ}[/tex]

[tex]\stackrel{\large{\frown}}{ADC} = 186^{\circ}[/tex]
