If the product of Sophia age and Moussa age is 24, the age of Moussa is 4 years.
How to find the Moussa's age?Moussa is younger than Sophia. Their ages are consecutive even integers.
The product of there ages is 24. Moussa's age can be found as follows:
Even numbers are those numbers that can be divided into two equal groups or pairs and are exactly divisible by 2.
Hence,
Let
x = age of Moussa
x + 2 = age of Sophia
Hence, the product of their age will be as follows:
x(x + 2) = 24
x² + 2x = 24
x² + 2x - 24 = 0
lets factorise the quadratic equation. The numbers one can multiply to get -24 and add to get 2 are -4 and 6. Therefore,
x² - 4x + 6x - 24 = 0
x(x - 4) + 6(x - 4) = 0
(x + 6)(x - 4) = 0
Therefore,
x = - 6 and x = 4
We can only use positive numbers.
Therefore, the age of Moussa is 4 years

Directions: Plot the positive rational numbers on the number line. 12 134.16 310 / 8 0 1 - 2.05 Warm-Up 2 + 3 4 5
Answer:
Step-by-step explanation:
To plot the positive rational numbers on the number line, you can use the following steps:Start by drawing a number line, with 0 at the left end and positive numbers increasing as you move to the right.Place the first number, 12, on the number line. You can place it to the right of 0, since it is a positive number.Place the next number, 134.16, to the right of 12. You can place it farther to the right, since it is a larger number.Place the next number, 310/8, to the right of 134.16. Since 310/8 is equal to 38.75, you can place it slightly to the right of 134.16, but still to the left of 39.Place the next number, 0, at the left end of the number line, since it is equal to 0.Place the next number, 1, to the right of 0, since it is a positive number.Place the next number, -2.05, to the left of 0, since it is a negative number.Place the final two numbers, 2 and 3, to the right of 1, since they are both positive numbers.The resulting number line should look something like this:-2.05 0 1 2 3 12 134.16 38.75 (310/8)
equation of a circle whose center at P (3,-7) and tangent to 2x+3y-4=0
Answer:
[tex](x-3)^2+(y+7)^2=\dfrac{361}{13}[/tex]
Step-by-step explanation:
The tangent of a circle is always perpendicular to the radius.
Therefore, the center is on a line that is perpendicular to the tangent.
Rearrange the equation of the tangent to make y the subject:
[tex]\begin{aligned}2x+3y-4&=0\\3y&=-2x+4\\y&=-\dfrac{2}{3}x+\dfrac{4}{3}\end{aligned}[/tex]
Therefore, the slope of the tangent line is -²/₃.
If two lines are perpendicular to each other, their slopes are negative reciprocals. Therefore, the slope of the perpendicular line is ³/₂.
To write the equation of the line perpendicular to the tangent, substitute the found slope and the center point into the point-slope formula:
[tex]\begin{aligned}y-y_1&=m(x-x_1)\\\implies y-(-7)&=\dfrac{3}{2}(x-3)\\y+7&=\dfrac{3}{2}x-\dfrac{9}{2}\\y&=\dfrac{3}{2}x-\dfrac{23}{2}\end{aligned}[/tex]
The point on the circle is the point of intersection of the tangent line and the perpendicular line.
To find the point of intersection, substitute the equation for the perpendicular line into the equation for the tangent line:
[tex]\implies \dfrac{3}{2}x-\dfrac{23}{2}=-\dfrac{2}{3}x+\dfrac{4}{3}[/tex]
[tex]\implies \dfrac{13}{6}x=\dfrac{77}{6}[/tex]
[tex]\implies x=\dfrac{77}{13}[/tex]
Substitute the found value of x into one of the linear equations and solve for y:
[tex]\implies y=-\dfrac{2}{3}\left( \dfrac{77}{13} \right)+\dfrac{4}{3}[/tex]
[tex]\implies y=-\dfrac{34}{13}[/tex]
Therefore, the point of intersection and hence the point on the circle is:
[tex]\left( \dfrac{77}{13}, -\dfrac{34}{13}\right)[/tex]
[tex]\boxed{\begin{minipage}{5 cm}\underline{Equation of a circle}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h, k)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]
To find r², substitute the given center of the circle (3, -7) and the found point into the equation of the circle:
[tex]\implies \left(\dfrac{77}{13} -3 \right)^2+ \left(-\dfrac{34}{13}+7\right)^2=r^2[/tex]
[tex]\implies \left(\dfrac{38}{13} \right)^2+ \left(\dfrac{57}{13}\right)^2=r^2[/tex]
[tex]\implies \dfrac{1444}{169} + \dfrac{3249}{169}=r^2[/tex]
[tex]\implies \dfrac{4693}{169}=r^2[/tex]
[tex]\implies \dfrac{361}{13}=r^2[/tex]
Therefore, the equation of the circle whose center is P(3, -7) and tangent to 2x+3y-4=0 is:
[tex]\boxed{(x-3)^2+(y+7)^2=\dfrac{361}{13}}[/tex]

Paul drives his delivery van 675 miles in 3 days. at this rate, how far will he drive in 15 days?
a. 45 miles
b. 225 miles
c. 2,025 miles
d. 3,375 miles
Therefore, the correct answer is 3,375 miles, or option (d) is the correct option.
To find out how far Paul will drive in 15 days, we need to determine his average distance per day and then multiply that number by 15. To find Paul's average distance per day, we can divide the total distance he drove in 3 days by the number of days:
675 miles / 3 days = 225 miles/day.
So Paul drives an average of 225 miles per day. If he continues to drive this same distance every day, he will drive 225 miles/day * 15 days = <<225*15=3375>>3,375 miles in 15 days.

A power outage affected all homes and businesses within a 5 mi radius of the power station. If the power station is located 1 mi west and 3 mi north of the center of town, find an equation of the circle consisting of the furthest points from the station affected by the power outage.
Answer: x^2 - 2x + y^2 - 6y + 10 = 0.
Step-by-step explanation: The power station is located 1 mi west and 3 mi north of the center of town, which means that it is located at the point (1, 3) on the coordinate plane. The power outage affected all homes and businesses within a 5 mi radius of the power station, which means that the furthest points from the station affected by the power outage are located on a circle with a radius of 5 mi.
The equation of a circle with center (h, k) and radius r is given by:
(x - h)^2 + (y - k)^2 = r^2
Substituting the values for the center of the circle (h, k) = (1, 3) and the radius r = 5, the equation of the circle consisting of the furthest points from the power station affected by the power outage is:
(x - 1)^2 + (y - 3)^2 = 5^2
This simplifies to:
x^2 - 2x + 1 + y^2 - 6y + 9 = 25
Combining like terms, the equation becomes:
x^2 - 2x + y^2 - 6y + 10 = 0
This can be written in standard form as:
x^2 - 2x + y^2 - 6y + 10 = 0
Therefore, the equation of the circle consisting of the furthest points from the power station affected by the power outage is x^2 - 2x + y^2 - 6y + 10 = 0.

In triangle DEF angle F i 120 degree and f= 4/3e. Find the meaure of angle D and angle E
The measure of the angle D and F can be calculated form the total measure of the Angle of the triangle that is 180.
In the triangle DEF, F is 120 degree and F is 4/3rd of E. A straight angle is just a straight line which is where it gets its name. the sum of a triangles angles 180. It is proved by angular defect and triangles area. The angle sum of a triangle will always be equal to 180°. The angle sum of a quadrilateral is equal to 360°, and a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral, its angle measures should be half as well.
Angle F = 120 degree
F= 4/3 E
E= 90 degree
The sum of the angle is 180. so,
D + E + F = 180
Putting all the values we can find the measure of angle D and Angle E.

x + 18 > 10
18 + 10 > x
the first inequality gives us

the second inequality would give us
x > -8
but with the first inequality x > 8 we have already a stronger criteria than x > -8 (if x > 8 is true, then so is automatically x > -8, but not the other way around).
