Answer:
15
Step-by-step explanation:
let total num of boys be X.
then,2/5 of X = 8
2 ×x = 40
X = 20
Now, let the total num of students be y,then we get,
4/7 of y = 20
4 × y = 140
y = 35
similarly, total num of girls = total num of students - total num of boys
= 35 - 20
= 15 ans

In the figure below, m
Il n ánd p || q. Find the values of x and y.
Answer:
114 and 30Step-by-step explanation:
The angles with measure of 66 and x are consecutive interior angles and therefore supplementary:
x + 66 = 180x = 180 - 66x = 114The angles x and 4y - 6 are alternate interior angles and therefore congruent:
x = 4y - 6114 = 4y - 64y = 114 + 64y = 120y = 120/4y = 30Find the slope of the line that contains (2, -10) and (-4, 2).
Answer:
Slope: -2
Step-by-step explanation:
(2, -10) and (-4, 2).
m = y1 - y2 / x1 - x2
m = -10-2/2-(-4)
m = -12/6
m = -2
what operation will eliminate the x variable in -6+6y=6

Enter the equation of the line in any format that we have learned that passes the two points: (2, -5) and (0, 1).
Given points:
(2, -5) and (0, 1)Find the slope:
m = (1 - (-5))/(0 - 2) = 6/(-2) = -3Point - slope form:
y - (-5) = -3(x - 2) ⇒ y + 5 = -3(x - 2)Convert into slope- intercept form:
y = -3x + 6 - 5 ⇒ y = -3x + 1Convert into standard form:
3x + y = 1[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
let's find slope (m) :

Y ∝ √ x If y = 42 when x = 9 find, y when x = 100
Answer:
y = 140
Step-by-step explanation:
Given y varies directly with [tex]\sqrt{x}[/tex] then the equation relating them is
y = k[tex]\sqrt{x}[/tex] ← k is the constant of variation
To find k use the condition y = 42 when x = 9 , then
42 = k [tex]\sqrt{9}[/tex] = 3k ( divide both sides by 3 )
14 = k
y = 14[tex]\sqrt{x}[/tex] ← equation of variation
When x = 100 , then
y = 14 × [tex]\sqrt{100}[/tex] = 14 × 10 = 140
here's a graph of a linear function. write the equation that describes that function.
Express it in slope-intercept form

Answer: t<=10
Step-by-step explanation:
-3t+9>=-21
-3t>=-30
3t<=30

cual es el menor numero cuya raiz cuadrada entera tiene dos cifras ?
Answer:
100
Step-by-step explanation:
The perfect square integers are:
1^2 , 2^2, 3^2, 4^2, 5^2, 6^2, ...
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, ...
We note from the list above that the smallest integer
whose square root is an integer of two digits is 100.
The next smallest perfect square is 81, and its square
root is 9, which is a one digit integer.
Carlos is going on a boat tour the boat will travel a total distance of 35 km during the seven hour tour if the boat travels at a consistent speed during the torr what distance in kilometers should the boat travel in three hours
Answer:
We can easily figure out how fast the boat is moving per hour.
35 km / 7 hours = 5 km/h
We now know that we are moving at a rate of 5 kilometers every 1 hour. We can now take our 5 km/h and multiply it by 3 hours to get our answer
5 km/h x 3 = 15 kilometers
