The difference in their ages is 12 and the sum of their ages is 50. Find the age of each. Jim is older than Ken.
Answer:
REMA = 31
KEN = 19
Step-by-step explanation:
Let R be Rema
Let K be Ken
R+K = 50
R-K= 12
R-12= K
R+ R-12= 50
2R= 50+12
2R= 62
R= 31
R- 12= K
31-12= K
19= K

a round clock has a radius of 5 cm. what is the approximate area of the clock? use 3.14
Answer:
78.5 cm^2
Step-by-step explanation:
The area of a circle can be found using:
[tex]a=\pi r^2[/tex]
We know that the radius is 5 cm. We also know that we are using 3.14 for pi. Therefore, we can substitute 5 in for r, and 3.14 in for pi.
a=3.14*5^2
Evaluate the exponent
a=3.14*(5*5)
a=3.14*25
Multiply
a=78.5
The area of the clock is 78.5 cm^2

If you were a college professor taking a survey of how many hours of
homework students were assigned, which visual tool would you use if you
organized students in hour ranges?
A. Line plot
B. Bar graph
C. Frequency table
D. None of the above
If I were a college professor taking a survey of how many hours of homework students were assigned and I wanted to organize the data by hour ranges, the visual tool that I would use is C) a frequency table.
Explanation:A frequency table would be the best visual tool to organize students in hour ranges for a survey of how many hours of homework students were assigned.
A frequency table is a way to organize data into different intervals, or ranges, and count how many data points fall into each interval. In this case, I would create intervals such as 0-1 hour, 1-2 hours, 2-3 hours, and so on, and then count the number of students assigned homework in each interval. This would give me a clear picture of the distribution of homework hours among the students. Therefore the correct answer is C) a frequency table.

Compare the period of y = 2x with the period of y= sin x
Final answer:
The function y = 2x is linear and without a period, whereas the function y = sin x is periodic with a period of 2π radians.
Explanation:
The period of a function is the length of the interval over which it repeats.
The function y = 2x is a linear function, not a periodic function, and thus does not have a period.
In contrast, the function y = sin x is a periodic function and has a period of 2π radians.
This means that the sine function repeats its values every 2π radians.
Therefore, when comparing the period of these two functions, we can conclude that y = 2x does not have a defined period, while y = sin x has a period of 2π radians.

Find the distance, c, between (0, 0) and (–4, –3) on the coordinate plane. Round to the nearest tenth if necessary.
Answer:
5 units.
Step-by-step explanation:
For this problem, you will need to use the distance formula. The distance formula is as shown:
d= [tex]\sqrt{({x_{2}-x_{1})^{2}+({y_{2}-y_{1})^{2} }[/tex]
We can plug in the points which would result in:
d= [tex]\sqrt{({-4-0)^{2}+(-3-0)^{2} }[/tex]
When solved:
d= [tex]\sqrt{25}[/tex]
d= 5 units
Need Help What is l9l
Answer:
the absolute value of l9l is 9
Step-by-step explanation:
because if you look on a number line when you are calculating the absolute value it is how many numbers away from zero so it is always positive.
Answer: +9
Step-by-step explanation: When an integer is written with vertical bars on either side, it means that we take the absolute value of that integer.
The absolute value of an integer is its
distance from zero on a number line.
|9| is +9 because it's 9 units from zero on the number line.

if there are 10 apples in the fridge and 7 on the table what is the ratio of apples in the fridge to apples on the table
Answer:
The correct answer would be 10 : 7
( OPINION ) I say this because we are comparing the apples in the fridge(10) to the apples on the table(7).
I hope this was helpful :3
STAY SAFE!! :)
The ratio of apples in the fridge to apples on the table is 10:7. This is calculated by dividing the number of apples in the fridge by the number on the table.
Explanation:The question asks for the ratio of apples in the fridge to the apples on the table. In order to solve this, you need to understand what a ratio is. A ratio is a way of comparing quantities. Here, the quantity being compared is apples: those in the fridge versus those on the table.
To calculate the ratio, you simply divide the first quantity by the second quantity. So in this case, you have 10 apples in the fridge and 7 apples on the table.
The ratio is therefore 10/7. This can also be written as 10:7.

Option B number line shows the solution set for |8 - 2p| = 6
What is number line?A number line is a pictorial representation of numbers on a straight line. It can be used to represent any real number that includes every whole number and natural number. Arithmetic operations of numbers can be better explained on a number line.
According to the question the given expression is |8 - 2p| = 6
Here the value of "p" is unknown. We have to assume a number and equate it to 6.
Let "p" be ±2, On applying ±2 in the set |8 - 2(±2)| =0
so not ±2
Now assume ±1, On applying ±1 in the set |8 - 2(±1)| =6
Value ±1 is shown in the 2nd number line.

Find how many six-digit numbers can be formed from the digits 2, 3, 4, 5, 6 and 7 (with repetitions), if:
the numbers formed must be divisible by 25
or
the odd digits must occupy even positions (i.e. 2nd, 4th, and 6th) and the even digits must occupy odd positions (i.e. 1st, 3rd and 5th)
Answer:
case 1 = 2592
case 2 = 729
case 1 + case 2 = 2916
(this is not a direct adition, because case 1 and case 2 have some shared elements)
Step-by-step explanation:
Case 1)
6 digits numbers that can be divided by 25.
For the first four positions, we can use any of the 6 given numbers.
For the last two positions, we have that the only numbers that can be divided by 25 are numbers that end in 25, 50, 75 or 100.
The only two that we can create with the numbers given are 25 and 75.
So for the fifth position we have 2 options, 2 or 7,
and for the last position we have only one option, 5.
Then the total number of combinations is:
C = 6*6*6*6*2*1 = 2592
case 2)
The even numbers are 2,4 and 6
the odd numbers are 3, 5 and 7.
For the even positions we can only use odd numbers, we have 3 even positions and 3 odd numbers, so the combinations are:
3*3*3
For the odd positions we can only use even numbers, we have 3 even numbers, so the number of combinations is:
3*3*3
we can put those two togheter and get that the total number of combinations is:
C = 3*3*3*3*3*3 = 3^6 = 729
If we want to calculate the combinations togheter, we need to discard the cases where we use 2 in the fourth position and 5 in the sixt position (because those numbers are already counted in case 1) so we have 2 numbers for the fifth position and 2 numbers for the sixt position
Then the number of combinations is
C = 3*3*3*3*2*2 = 324
Case 1 + case 2 = 324 + 2592 = 2916

Find the slope of the line that goes through the points (-3, -4) and (0, -1).
A. LaTeX: \frac{4}{3}4 3
B. -1
C. LaTeX: \frac{3}{4}3 4
D. 1
Answer:
D
Step-by-step explanation:
The slope is the change in y-coordinates divided by the change in x-coordinates.
Here, the y-coordinates are -4 and -1, and the x-coordinates are -3 and 0, so:
slope = m = (-4 - (-1)) / (-3 - 0) = -3 / -3 = 1
The slope is thus 1, so the answer is D.
We can use the points (-3, -4) and (0, -1) to solve.
Slope formula: y2-y1/x2-x1
= -1-(-4)/0-(-3)
= 3/3
= 1 (Option D)

A 12 foot ladder is placed 4 foot from the bottom of the house. How high will the ladder reach the house?
Answer:
11.31 ft
Step-by-step explanation:
Here in this problem ladder forms a right triangle with the wall of the house and it is acts as hypotenuse, length of one leg of right triangle given to be 4 feet.
Let the ladder reaches x ft height of the house.
Hence, by Pythagoras theorem:
[tex] {12}^{2} = {4}^{2} + {x}^{2} \\ 144 = 16 + {x}^{2} \\ {x}^{2} = 144 - 16 \\ {x}^{2} = 128 \\ x = \sqrt{128} \\ x = 11.3137085 \\ x = 11.31 \: ft[/tex]
Hence, the ladder reaches 11.31 ft height of the house.
What is the distance, rounded to the nearest tenth, between the points (-5,3) and (1,-1)? Enter the answer in the box.
units
Final answer:
The distance between the points (-5,3) and (1,-1) is found using the distance formula and is approximately 7.2 units when rounded to the nearest tenth.
Explanation:
To find the distance between two points (-5,3) and (1,-1), we can use the distance formula: √((x2 - x1)² + (y2 - y1)²). Plugging in our values, we get the distance as √((1 - (-5))² + (-1 - 3)²) = √(6² + (-4)²) = √(36 + 16) = √52. To round to the nearest tenth, we calculate √52 and find it is approximately 7.2. Therefore, the distance between the points, rounded to the nearest tenth, is 7.2 units.
