Answer:
4<x<12
Step-by-step explanation:
8.0+4.0=12.0
8.0-4.0=4.0 or 4
The rules of triangles is that it must be less than the sum you had when you first added 8.0and 4.0 which was 12
So therefore , 4< x < 12
and I also got it right on khan academy lol
Sarah is watching a video online that is 246.987 seconds long. She writes this time in expanded form. Which expression represents the value of one of the digits in the length of the video?
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:
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
Trigonometry Practice
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
Chuck goes to a community college. There is an enrollment fee of $207.55, plus $223.07 per credit hour. Which equation
shows C, the total cost of attending the community college, for x credit hours?
OA.
C= $207.55x - $223.07
OB.
C= $207.55x + $223.07
O C.
C= $223.07x + $207.55
OD.
C = $223.07x- $207.55
3. Would it be more efficient to use an inequality vo
or to list all of the quantities less than 6? Explain.
Answer:
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

The ratio of the measures of the angles of a triangle is 5:6:7 find the measures of the angles of the triangle.
Answer:50°
Step-by-step explanation:
Let x represent the scale factor, the ratios are multiplied by:
5x°+6x°+7x°=180°
18x°=180°
x=10
Smallest Angle 5x°=5(10)°=50°

Answer:

Step-by-step explanation:
Jose drove to the mountains last weekend. There was heavy traffic on the way there, the trip took eight hours. When jose drove home, there was no traffic and the trip only took five hours. If his average rate was 21 mph faster on the trip home, how far away does jose live from the mountains
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
How do you write this polynomial in standard form?
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.

X and y
Answer:
X=5 y=7
Step-by-step explanation:
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

How might snakes running out of food affect other organisms such as hawks? please help
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.

What is the arc measure, in degrees, of major arc \stackrel{\large{\frown}}{ADC} ADC ⌢ A, D, C, start superscript, \frown, end superscript on circle PPP below?
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]

Which of the following statements is not true?
-1 < -1.5
1.7 > 1
≤
0.01 < 0.1
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
Five-foot-tall Melody casts an 84-inch shadow. How tall is her friend if, at the same time of day, his shadow is 1 foot shorter than hers?
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.
The sea floor is 104 feet below sea level. Katy is 28 feet below sea level. She is moving downward at a rate of 4 feet per minute. Colin used the following calculation to determine how long it will take Katy to reach the sea floor. Is he correct? Explain.
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.
