Dos hermanos , Juan de 12 años y Rafael de 15, reciben como herencia de su padre un terreno de cultivo de 36 hectáreas (ha).Si la repartición fue de forma proporcional a sus edades , ¿Cuantas hectáreas le tocará a cada uno?
Answer:
16 hectáreas y 20 hectáreas
Step-by-step explanation:
Aquí, debemos compartir las 36 hectáreas con respecto a la proporción de sus edades.
Lo primero que debe hacer aquí es colocar su edad de lado a lado y encontrar la relación con el término más bajo.
Por lo tanto; 12:15 al término más bajo es 4: 5 Entonces debemos compartir 36 hectáreas en la proporción 4: 5
Primero, sumamos ambos y tenemos 4 + 5 = 9
Entonces; 4/9 * 36 = 16 hectáreas
5/9 * 36 = 20 hectáreas
The question i want to know is linked below. Please help :)
Answer:
Hey there!
To solve this problem, we want to find the LCM (least common multiple) of the two numbers.
The numbers are 25 and 30.
25=5x5
30=2x3x5
LCM is 5x5x2x3, or 150.
Thus, in 150 minutes is when the next bus will leave.
150 mins is equal to 2 hours and 30 mins, or 2.5 hours.
8 AM + 2.5 hrs = 10:30 AM.
Thus, the next time the busses leave together would be at 10:30 AM.
Let me know if this helps :)
The power, P (watts) , of a car engine is proportional to the square of its speed, s ( m / s ) . When s = 15 , P = 2100 . Work out the speed (to 1 DP) when the power is 2200 watts
Answer:
The speed of the car engine is 15.4m/s
Step-by-step explanation:
Given
Power = 2100; when Speed = 15
Required
Find Speed when Power = 2200
The question says power is proportional to square of speed;
Mathematically;
[tex]Power\ \alpha \ Speed^2[/tex]
Represent Power with P and Speed with S
[tex]P\ \alpha \ S^2[/tex]
Convert proportion to an equation
[tex]P\ = \ kS^2[/tex]
Where k is proportionality constant
Make k the subject of formula
[tex]\frac{P}{S^2} = k[/tex]
When P = 2100 and S = 15
[tex]\frac{2100}{15^2} = k[/tex]
When P = 2200 and S is unknown
[tex]\frac{2200}{S^2} = k[/tex]
Recall that [tex]\frac{2100}{15^2} = k[/tex]
So;
[tex]\frac{2200}{S^2} = k[/tex] becomes
[tex]\frac{2200}{S^2} = \frac{2100}{15^2}[/tex]
Cross Multiply
[tex]S^2 * 2100 = 2200 * 15^2[/tex]
[tex]S^2 * 2100 = 2200 * 225[/tex]
[tex]S^2 * 2100 = 495000[/tex]
Divide both sides by 2100
[tex]S^2 = \frac{495000}{2100}[/tex]
[tex]S^2 =235.714285714[/tex]
Take Square Roots of both sides
[tex]S = \sqrt{235.714285714}[/tex]
[tex]S =15.3529894716[/tex]
[tex]S = 15.4[/tex] (Approximated)

blanca buys 2 gallons of green paint. she needs 5 quarts to paint her front porch and 1/2 quart to paint the front porch swing. how many quarts of paint does blanca have left
Answer:
0.625 gallons
Step-by-step explanation:
1 gallon = 4 quarts
2 gallons = 2 × 4 quarts = 8 quarts
She used = 5 quarts
Usage of paint the front porch swing = quart = 0.5 quart
used paint = 5 + 0.5 = 5.5 quarts
subtract used paint by starting amount
paint that was not used= 8 quarts - (5.5 quarts) = 2.5 quarts.
used green paint is 2.5 quarts or 0.625 gallons.

We will the pythagorian theorem :
let x be the third side x²+6²= 10²x²= 100-36 x=[tex]\sqrt{64}[/tex] x=8Answer:
b=8
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle:
a^2+ b^2 = c^2 where a and b are the legs and c is the hypotenuse
a=6 and b = 10
6^2 + b ^2 = 10^2
36+ b^2 = 100
b^2 = 100-36
b^2 = 64
Taking the square root of each side
sqrt(b^2) = sqrt(64)
b = 8

Can someone plz help me Solve this Equation Solve for X
Answer:
x = 4
Step-by-step explanation:
If two secants are drawn to a circle from one exterior point, then the product of the exterior segment and whole segment is same. i.e 6×(6+x) = 5×(5+x+3)
=> 6x+36 = 5x + 15 +25
=> x = 40-36
=> x = 4
I hope it's the right answer.
Answer:
x = 4
Step-by-step explanation:
Given 2 secants drawn to a circle from an external point, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
6(6 + x) = 5(5 + x + 3), that is
36 + 6x = 5(8 + x) = 40 + 5x ( subtract 5x from both sides )
36 + x = 40 ( subtract 36 from both sides )
x = 4

i need this answer rn A triangular pyramid has a base shaped like an equilateral triangle. The legs of the equilateral triangle are all 5 inches long, and the height of the equilateral triangle is 4.3 inches. The pyramid's slant height is 5 inches. What is its surface area?
Answer:
48.25 in^2.
Step-by-step explanation:
Surface area of the base
= 1/2 & base * height
= 1/2 * 4.3 * 5
= 10.75 in^2.
Area of each triangular side
= 1/2 * 5 * 5
= 12.5 in^2.
So total surface area
= 10.75 + 3 * 12.5
= 48.25 in^2.

There is a bag filled with 3 blue and 4 red marbles. A marble is taken at random from the bag, the colour is noted and then it is not replaced. Another marble is taken at random. What is the probability of getting 2 reds?
Answer:
2/7
Altogether there're 7 marbles. Let,probability of getting blue and red marbles be 'B' and 'R' respectively.
In 1st pick
Probability of getting red marble is 4/7
So, there's the probability that the ball in 1st pick may be either blue or red.
So,if the marble is red then we've to eliminate that red marble ( cause,question says so)
Then,in 2nd pick
Probability of getting red ball will be 3/6(if we eliminate that red ball then the total number of marbles will also be 6)
Now,
Probability of getting two red will be
(4/7)×(3/6)
=2/7

Find the area of this triangle..
Answer:
Step-by-step explanation:
For this problem, we have to use Heron's Formula.
S= (a + b + c)
over 2
And then √S( S-a) (S-b) (S-c)
That's the formula, now to plug in the numbers.
S= 12+12+21.2
over 2
that equals 45.2/ 2= 22.6'
Now we found s, so we can plug in the second step of the formula...
√22.6 ( 22.6 - 12 ) ( 22.6 - 12 ) ( 22.6 - 21.2 )
This equals √ 22.6 (10.6) (10.6) (1.4)
and that equals...
59.624411 = or rounded it up to 60.

What is the value of y?
Answer:
C. 55
Step-by-step explanation:
Since all angles in a triangle add up to 180°, we have:
40 + y + y + 30 = 180
2y + 70 = 180
2y = 110
y = 55
Answer:
C. 55º
Step-by-step explanation:
A triangle is 180º.
So, 40+y+30+y = 180º Form an equation to solve it. Then combine like terms
70+2y = 180º Subtract 70 on both sides.
2y = 110º Divide 2 on both sides
y = 55º The answer is 55º

A group of students takes a test and the average score is 72. One more student takes the test and receives a score of 88 increasing the average score of the group to 76. How many students were in the initial group
Answer:
3 student.
Step-by-step explanation:
From the first statement:
Let the total score be T
Let the total number of student be x
The average of the score = 72
Average = Tota score / number of student
72 = T/x
Cross multiply
T = 72x ..... (1)
Second statement:
One more student took the test and the average becomes 76 with the student having a score of 88.
Therefore,
Overall score = T + 88
Total student = x + 1
Average = 76
Average = overall score / total number of student
76 = (T + 88) /(x + 1)
Cross multiply
76(x + 1) = T + 88
Clear bracket
76x + 76 = T + 88
From equation 1
T = 72x
76x + 76 = 72x + 88
Collect like terms
76x – 72x = 88 – 76
4x = 12
Divide both side by the coefficient of x i.e 4
x = 12/4
x = 3
Therefore, the initial number of the student were 3.
A system of equations is shown on the graph below. How many solutions does this system have?
Answer:
[tex]\boxed{1 \: \: \mathrm{solution}}[/tex]
Step-by-step explanation:
The point where two lines intersect is the solution to the system of equations.
The two lines intersect at (-1, 2).
x = -1
y = 2
y = 2x + 4
y = -x + 1
Plug y as -x+1 in the first equation.
-x + 1 = 2x + 4
-x - 2x = 4 - 1
-3x = 3
x = -1
Plug x as -1 in the second equation.
y = -(-1) + 1
y = 1 + 1
y = 2
Answer:
Hey there!
Only one solution, because they intersect at only one point.

The cost of a trip is $3.15 plus $0.95 for every kilometre that you ride on a bus. Which of the following expressions gives the cost of a trip of k kilometres?
Answer: 0.95k + 3.15
Step-by-step explanation:
0.95k is because each of k kilometers costs $0.95. + 3.15 is because it costs 3.15 as a flat rate regardless of distance
Hope it helps <3
Answer:
.95k+3.15
Step-by-step explanation:
To write an expression you need a variable (k). I look at the directions and I see that the length of the trip is 'k' kilometers. So I pay the flat fee of 3.15 ONE TIME. Then I pay $0.95 for every kilometer I go, so the expression is
-> .95k+3.15

The radius of the semi circle will be:
Radius r = diameter/ 2
Where diameter = 140
r = 140/2 = 70m
The radius is also equal to the width of the diameter.
Find the quarter of the circumference of a circle.
Circumference of a circle = 2πr
Substitute for r in the formula
Circumference = 2 × 22/7 × 70
Circumference = 44 × 10 = 440 m
Divide the circumference by 4
440/4 = 110 m
The perimeter P of the shaded region will be
P = 110 + 70 + 70
Perimeter = 250 m
Therefore, the perimeter of the shaded region is 250 m
Solve the system of equations by substitution.

Answer:
Point Form:
( − 46 /3 , − 44 /3 )
Equation Form:
x = − 46 /3 , y = − 44 /3
Step-by-step explanation:
Combine 1 /2 and x .
y = x /2 − 7
2 x − y = − 16
Replace all occurrences of y in 2 x − y = − 16 with x /2 − 7 .
y = x /2 − 7
2 x − ( x /2 − 7 ) = − 16
Simplify
2 x − ( x /2 − 7 ) .
y = x /2 − 7
3 x /2 + 7 = − 16
Solve for
x
in the second equation.
y = x /2 - 7
x = − 46 /3
Replace all occurrences of x in y = x /2 − 7 with − 46 /3 .
y = − 46 /3 /2 − 7
x = − 46 /3
Simplify − 46 /3 /2 − 7 .
y = − 44 /3
x = − 46 /3
The solution to the system of equations can be represented as a point.
( − 46 /3 , − 44 /3 )
The result can be shown in multiple forms.
Point Form:
( − 46 /3 , − 44 /3 )
Equation Form:
x = − 46 /3 , y = − 44 /3
