Find three consecutive integers that sums to 15. Show your equation and all work.
Answer:
4, 5, 6
Step-by-step explanation:
Represent the first number by x. Then the next two consecutive integers are x + 1 and x = 2.
THEN x + x + 1 + x + 2 = 15, WHICH REDUCES TO 3x + 3 = 15.
Then 3x = 12, and x = 4.
The consecutive integers are 4, 5 and 6.

Answer:
289 units
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = πd ( d is the diameter )
Here C = 907.46 , thus
907.46 = πd ( divide both sides by π )
d = [tex]\frac{907.46}{\pi }[/tex] ≈ 289 units ( nearest whole number )
Answer:
[tex]d = 288.84 \: \: \: units[/tex]
Step-by-step explanation:
Using the formula
[tex]c = 2\pi \: r[/tex]
Solving for r
[tex]r = \frac{c}{2\pi} = \frac{907.46}{2\pi} \\ = 144.42674 \\ [/tex]
Now lets find the diameter
[tex]d = 2r \\ d = 2 \times 144.42 \\ d = 288.84 \: units[/tex]
hope this helps

If X^2 = 4
Does X = 2 or X = -2
Answer:
Both.
Step-by-step explanation:
[tex]x^2=4[/tex]
[tex]x=\±\sqrt{4}[/tex]
[tex]x=\± 2[/tex]
Answer:
Yes
Step-by-step explanation:
If,
X² = 4
Taking square root on both sides
[tex]\sqrt{x^2} = \sqrt{4}[/tex]
So, It becomes
X = ±4
Either
X = 2 OR X = -2

a pair of shoes is originally priced at 120 It is on sale for 35% off . Find the total percent that you would pay a .35% b.120% c.65% d70%
Answer:
C
Step-by-step explanation:
Im not exactly sure about this, but i think for the first step, you would do 120*35/100=42 (35/100 is 35%). Then you take 120 and subtract 42, cuz thats how much you took off. 120-42=78. Then, you do 78/120*100 to get the percent you have left. 78/120*100=65%. The simpler way to do it, seeing as there arent mutiple sales on this pair of shoes, is just subtract 35 from 100 to get 65%
Answer:
c: 65% of the answer
Step-by-step explanation:
$120 is 100% we need to find the discount which is 100%-35% = 65%
You will pay now $78 for the shoes.
cross-check 120/100*65 = $78

William, Nancy, and Edgar met at the lodge at 8 AM. William began hiking west at 3 mph. At 10 AM Nancy began hiking north at 5 mph and Edgar went east on a three wheeler at 12 mph. At what time was the distance between Nancy and Edgar 10 miles greater than the distance between Nancy and Willam? ____:____ AM/PM
Answer:
12:00 AM
Step-by-step explanation:
Taking the lodge as the center of the coordinate system, the position of each person is:
William: 6+3*t
Nancy: 5*t
Edgar: 12*t
where t is in hours after 10:00 am
Between the positions of William and Nancy, a right triangle is formed, where their distance is the hypotenuse.
WN = √[(5*t)² + (6+3*t)²]
Similarly, Between the positions of Nancy and Edgar:
NE = √[(5*t)² + (12*t)²]
If the distance between Nancy and Edgar is 10 miles greater than the distance between Nancy and Willam, then
NE = WN + 10
√[(5*t)² + (12*t)²] = √[(5*t)² + (6+3*t)²] + 10
With the help of the graph of this equation, we find that t = 1.95 or approximately 12:00 AM

Find x, y and z to the nearest hundredth.
Answer:
see explanation
Step-by-step explanation:
This is an example of the Altitude - on - Hypotenuse theorem.
The altitude that is perpendicular to the hypotenuse of a right triangle.
The two triangles formed are similar to the given triangle and to each other.
x² = (smaller part) × (larger part) of main hypotenuse
x² = 6 + 19 = 114 ( square root both sides )
x ≈ 10.68 ( nearest hundredth )
---------------------------------------------
y² = ( smaller part) × (whole part) of main hypotenuse
y² = 6 × 25 = 150 ( square root both sides )
y ≈ 12.25 ( nearest hundredth )
--------------------------------------------
z² = ( larger part) × (whole part) of main diagonal
z² = 19 × 25 = 475 ( square root both sides )
z ≈ 21.79 ( nearest hundredth )

10. 903.6 - 25.1
Exact Answer:
Estimate:
11. 760.38 +0.38
Exact Answer:
Estimate:
Answer
10) 36
11)2001
Step-by-step explanation:
Answer:
10. 36 (exact answer), 30 or 30.16 (estimated answer).
11. 2001 (exact answer), Undefined, or 1900 (estimated answer).
Step-by-step explanation:
For number 10, the exact answer is 36 and the estimated is 30 or 30.16. Why?
-To have the exact answer we have to divide 903.6 ÷ 25.1 = 36.
-To have the estimated answer we have to round 903.6 and 25.1, as 903.6 is close to 900 and not 1,000, and 25.1 is close to 30 and not to 20. The equation is 900 ÷ 30 = 30.
-To make sure that the exact answer is correct, we have to multiple 25.1 and 36 = 903.6.
-To make sure that the estimated answer is correct, we have to multiple 30 and 30 = 900.
-But there's a problem, they can be two answers for the estimated answer 1). 30, and 2). 36.16. Process: 904 ÷ 25 = 36.16. Why? As they are decimal points, it may be that we have to round them but not the whole number, but the question doesn't specify how we have to round them, so I'm not so clear about it.
For number 11, the exact answer is 2001 the estimated is 1900 or Undefined. Why?
-To have the exact answer we have to divide 760.38 ÷ 0.38 = 2001.
-To have the estimated answer for the undefined we have to round 760.38 and 0.38, as 760.38 is close to 800 and not to 700, and 0.38 is close to 0 (0.00) and not to 1 (1.00). The equation is 800 ÷ 0.00 = Undefined.
-To make sure that the exact answer is correct, we have to multiple 2001 and 0.38 = 760.38.
-But there's a problem, they can be two answers for the estimated answer 1). Undefined, and 2). 19. Process: 760 ÷ 0.40 = 1900. Why? As they are decimal points, it may be that we have to round them but not the whole number, but the question doesn't specify how we have to round them, so I'm not so clear about it.

some teachers traveled to school by car the table shows the number of teachers in the cars a) what was the modal number of teachers in a car b) what was the median number of teachers in a car c) what was the mean number of teachers in a car
Answer:
Step-by-step explanation:
since it is asking for the modal that means the most so it would be 3 teachers, and when asking the median we have to change the order so it would be 2,3,4,6 and we find the middle so it would be 3.5, and the mean is the total of the numbers divided by how many numbers there are so it would 2+6+4+3=
15/10 = 1.5
A mean is an arithmetic average of a set of observations. The model number, median, and mean of the number of teachers in a car are 3, 3, and 2.46667, respectively.
What is Mean?A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
The given table can be written in the data form as 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4.
A.) The modal number is the mode of a given data set. Therefore, the mode of the given data set is 3.
B.) The median is the middle number of a given data set. Therefore, the median is 3.
C.) The mean is the average number of teachers in a car. Therefore, the mean is,
Mean = (1+1+1+2+2+2+2+3+3+3+3+3+3+4+4)/15 = 37/15 = 2.46667
Hence, the model number, median and the mean of the number of teachers in a car is 3, 3, and 2.46667, respectively.

A train travels at a speed of 45 kmph. In 48 minutes, how much distance will it travel? ( with explanation )
Answer:
36 km
Step-by-step explanation:
By dividing 45 by 60 you make it into .75 per minute therefore by multiplying by 48 you get your answer which is 36 km
Answer:
36 km
Step-by-step explanation:
We are given a speed in km per hour. Since 1 hour = 60 minutes, we can find the speed in km per minute.
45 kph = 45 km/hour = 45 km/(60 minutes) = 0.75 km/minute
Now that we know the speed in km per minute, we multiply the speed by 48 minutes to find the distance traveled in 48 minutes.
0.75 km/minute * 48 minutes = 36 km
