Ivan has 6 times as many blue beads as red beads. he has 49 red and blue beads in all. how many blue beads does Ivan have
salantis [7]

Let

x--------> the number of blue beads

y--------> the number of red beads

we know that

x+y=49

x=49-y -------> equation 1

x=6y ------> equation 2

equate equation 1 and equation 2

49-y=6y\\ 6y+y=49\\ 7y=49\\\\ y=\frac{49}{7} \\  \\ y=7

find the value of x

x=6*7\\ x=42

therefore

the answer is

Ivan has 42 blue beads

Find the equation for the plane through the points Upper P 0 (4 comma 5 comma negative 3 )P0(4,5,−3)​, Upper Q 0 (1 comma 4 comm
alexira [117]

Answer:

  4x -4y +z = -7

Step-by-step explanation:

The direction vector will be perpendicular to any/all vectors between the given points. It can be found, for example, using the cross product:

  d = (P0Q0) × (P0R0) = (-3, -1, 8) × (-4, -3, 4)

The cross product can be computed by hand or by any of a number of calculators or web tools. Here it will be ...

  d = (20, -20, 5)

These can be the coefficients of x, y, and z in the plane equation. However, the equation is better written using coefficients that are mutually prime, so we choose the direction vector to be ...

  d = (4, -4, 1)

The constant C in the plane equation

  d·(x, y, z) = C

will be the dot product of this direction vector (d) any any of the given points. Using R0, we find the constant to be ...

 C = (4, -4, 1)·(0, 2, 1) = 4·0 +(-4)·2 +1·1 = -8+1 = -7

so, the plane equation is ...

  4x -4y +z = -7

An 11 foot ladder leans against the side of a house. The bottom of the ladder is 6 feet from the side of the house. How high is
Mariulka [41]
Using Pythagoras Theorem,
(b is the length of the ladder from the ground)
11x11=6x6+(b^2)
121-36=(b^2)
85=(b^2)
b= 9.219544457292887
b is approximately 9.2
