1. Arun can walk 15 km in 3 hours. How far can he
walk in 4 hours?
Answer:
Step-by-step explanation:
15/3 = x/4
if you multiply you get 3x= 4*15.
4 times 15 is 60, then divide by 3 to get 20
Arun can walk 20 km in 4 hours.
Answer:
20 km.
Step-by-step explanation:
First, divide 15 by 3 to find out how many kilometers Arun can walk in a single hour.
15/3=5
To find out how far he can walk in 4 hours, multiply 4 by the number of kilometers he can walk in an hour, which is 5.
4x5=20
Therefore, Arun can walk 20 km in 4 hours.
Hope this helps you out and have a great day (^人^)

Answer:
c = 18π exact answer
c = 56.52 decimal approximation
Step-by-step explanation:
c = 2πr
c = 2π * 9
c = 18π exact answer
Using 3.14 for π
c = 18 * 3.14
c = 56.52 decimal approximation

Hey!! Can any of y'all help me find the center and radius of this equation?
x^2+y^2-8x+2y=-8
Answer:
Center: (4,-2)
Radius: 2√3 units
Step-by-step explanation:
We wish to find the center and radius of the equation x²+y²-8x+2y=-8
Step 1: Complete the square for both variables:
x²+y²-8x+2y=-8
x²-8x+y²+2y=-8 (Rearrange)
x²-8x+16+y²+2y+4=-8+16+4 (Add to both sides)
(x-4)²+(y+2)²=12 (Reduce trinomials)
Step 2: Interpret the center and radius of the circle:
The equation of a circle is (x-h)²+(y-k)²=r² where (h,k) is the center of the circle and r is the radius of the circle. Since (h,k) translates to (4,-2), this means the center of the circle is (4,-2). Since r²=12, then r=√12=2√3 units

Which choices are equivalent to the expression below? Check all that apply. Sqrt -36 A. -6 B. I sqrt36 C. 6i D. - sqrt36
Answer:
6iStep-by-step explanation:
Given the expression √-36
This can also be written as;
√36 = √36 * √-1
Since i² = -1
√-1 = i
Substitute into the resuting expression
√-36 = √36 * i
√-36 = 6i
Hence the required answer is 6i
Answer: The answer is i sqrt 36 and 6i

Maria y juan deben realizar el mapamundi en medio pliego de cartulina para la tarea de sociales pero cada uno tiene un cuarto de cartulina maria le dice a su compañero que si unen los cuartos de cada uno obten dran el medio pliego que necesitan . Maria tine razon justifica tu rrespuesta
Answer:
Cuando María afirma que si unen sus dos cuartos de cartulina obtendrán el medio pliego que necesitan, esto es:
Verdadero.Step-by-step explanation:
Para entender mejor el ejercicio vamos a utilizar números cada vez que se habla de cantidades de cartulina, por lo tanto, María y Juan tienen 1/4 de cartulina cada uno, es decir, 1/4 * 2, y necesitan 1/2 pliego para poder realizar su tarea, por lo tanto, con la afirmación de María sobre unir los dos cuartos de cartulina, en caso de que sea verdadero, ocurrirá que la suma de los dos cuartos dará el medio pliego, como se muestra a continuación:
Total de cartulina de María y Juan = [tex]\frac{1}{4}+\frac{1}{4}[/tex]Total de cartulina de María y Juan = [tex]\frac{4+4}{16}[/tex]Total de cartulina de María y Juan = [tex]\frac{8}{16}[/tex]Procedemos a simplificar el fraccionario obtenido, sacando mitad tanto en el numerador como en el denominador:
Total de cartulina de María y Juan = [tex]\frac{4}{8}[/tex]Total de cartulina de María y Juan = [tex]\frac{2}{4}[/tex]Total de cartulina de María y Juan = [tex]\frac{1}{2}[/tex]Como puedes ver al final, la cantidad de cartulina de ambos, al ser sumada, da como resultado el 1/2 (medio) pliego que necesitan para su tarea de sociales, por lo cual la afirmación de María es correcta.
The sum of David and Jacobs age is 39. Two years ago David was four times Jacobs age. How old are three now?
Answer:
David is 30
Jacob is 9
Step-by-step explanation:
The sum of David and Jacobs age is 39
d + j = 39
d = 39 - j
----------------------
Two years ago David was four times Jacobs age
(d - 2) = 4(j - 2)
d - 2 = 4j - 8
d = 4j - 6
---------------------
Set the equations equal
4j - 6 = 39 - j
5j = 45
j = 9
d = 4(9) - 6
d = 30
Jill sold one third of her dolls and bought 15 more she now has 25 dolls with how many did she start?
Answer:
15
Step-by-step explanation:
sold 1/3 so 2/3 remain
(2/3)x + 15 = 25
Subtract 15 from both sides
(2/3)x = 10
Multiply both sides by 3/2
x = 15

Written as a simplified polynomial in standard form, what is the result when (3x+7)^2 is subtracted from 3?
Given:
[tex](3x+7)^2[/tex] is subtracted from 3.
To find:
The result of the given statement in the standard form of the polynomial.
Solution:
We need to find the result when [tex](3x+7)^2[/tex] is subtracted from 3.
So, the resulted polynomial can be written as:
[tex]P(x)=3-(3x+7)^2[/tex]
On simplification, we get
[tex]P(x)=3-((3x)^2+2(3x)(7)+(7)^2)[/tex] [tex][\because (a+b)^2=a^2+2ab+b^2][/tex]
[tex]P(x)=3-(9x^2+42x+49)[/tex]
[tex]P(x)=3-9x^2-42x-49[/tex]
[tex]P(x)=-9x^2-42x-46[/tex]
Therefore, the resulted polynomial in standard form is [tex]-9x^2-42x-46[/tex].

The table shows the heights of the 5 tallest mountains in the world. Find the mean, median, and range
of the heights.
Answer: The median is 28208 the mean is 28234.6
Step-by-step explanation:
The mode is the number that is repeated the most there can be more than one mode.
Answer:
All in ft
Mean: 28,235
Median: 28,208
Range: 1,245
Step-by-step explanation:
Mean is the sum of the elements divided by the number of elements.
(29035+28250+28208+27890+27790)/5 = 28235
Median is the element in the exact middle of the set (if there is an even number of elements, take the average of the two elements in the middle).
After rearranging the numbers, we can see 28208 is in the exact middle.
27790 27890 28208 28250 29035
Range is the difference between the smallest and largest number in the set.
29035-27790=1245
