What is meant by decimal number?Integer and non-integer numbers are often expressed using the decimal numeral system.
Decimals are a type of number in algebra that have a whole number and a fractional portion separated by a decimal point. The decimal point is the dot that separates the whole number from the fractional part of the number.
The term "decimal" refers to the base-10 number system, which is arguably the most widely used. The ten single-digit numbers that make up the decimal number system are 0 through 9, or just 1, 2, 3, 4, 5, 6, and 7. 10 is the number that follows 9. 20 comes follows the number 19, and so on.

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.

OB.
C= $207.55x + $223.07
O C.
C= $223.07x + $207.55
OD.
C = $223.07x- $207.55
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.

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

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

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
