If the projections of vector à on x, y and z axis are 2,1,2 units respectively, find the angle at which vector à is inclined to the z-axis ​

Answer:

4x-12

Step-by-step explanation:

4 x x is 4x and 4x-3 is -12

Answer:

110 degrees

Step-by-step explanation:

Because these angles are vertical, 5x+15=8x-42. thus, 15=3x-42, 3x=57, and x=19. 5x+15=5(19) +15=110. So, m<CDE=110 degrees.

Answer:

110°

Step-by-step explanation:

Since CDE and FDG are vertical, they are congruent, so:

5x + 15 = 8x - 42

Solve the equation for x

57 = 3x

19 = x

Then solve for one of the angles (I chose CDE but FDG would also work)

5(19)+15

95 + 15

110

Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.

Step-by-step explanation:

Let slice of pizza cost x and a 12-ounce cola cost y.

Then Sara's order cost: 2x+y=3

and Sydney's order cost: 3x+2y=4.75

From the first equation we have: y=3-2x and put this to the second equation:

3x+2(3-2x)=4.75

3x+6-4x=4.75

x=1.25

y=3-1.25*2=0.50

Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.

Answer:

The equation is 18h=378

h=21

Step-by-step explanation:

So first you have to set up the equation

so if she makes 18 dollars an hour the first part of the equation would be 18h

She made 378 dollars in one week so now the equation is 18h=378

The answer is h=21 because 378/18 is 21

Answer:

He bought 20 balls

Step-by-step explanation:

Cost of a certain number of golf balls = $20

Let 1 golf ball cost $x

This means number of balls bought = 20 / x

If each ball has costed 20 cents less;

Converting 20 cents to dollars = $0.2

$x - $0.2

he could have bought five more for the same money.

Number of balls = 20/x + 5

Using the formulae;

Cost of 1 ball * Number of balls bought = Amount spent

(x-0.2) (20/x + 5) = 20

Expanding the expression;

x(20/x + 5) - 0.2(20/x + 5) = 20

20 + 5x - 4/x - 1 = 20

19 + 5x - 4/x = 20

5x - 4/x = 1

Multiplying all through by x

5x^2 - 4 = x

5x^2  - x - 4 = 0

(5x + 4)(x - 1) = 0

x = 1 or -4/5

-4/5 is unrealistic hence the correct value is;

x = $1

He bought 20 balls;  20 / x = 20 / 1 = 20

The reduction in the price of each ball increases the number of balls the man can buy at RM 20.

The number of balls he bought is 20 balls.

Reasons:

The given parameters are;

The amount the man bought the golf balls = RM 20

The number of golf balls he could have bought if each ball costs 20 cents less = 5 more balls

Let the number of balls the man bought = x

Let the price of each ball be m

We have;

m × x = 20

(x + 5)·(m - 0.20) = 20

Therefore, we get;

[tex]m = \dfrac{20}{x}[/tex]

Which gives;

[tex]\left(x + 5 \right) \cdot \left(\dfrac{20}{x} - 0.20\right) = 20[/tex]

[tex]-\dfrac{\left(0.2 \cdot x^2- 19 \cdot x - 100\right)}{x} = 20[/tex]

20·x = -0.2·x² + 19·x + 100

0.2·x² + x - 100 = 0

x² + 5·x - 500 = 0

(x + 25)·(x - 20)

x = 20

The number of balls he bought, x = 20 balls

Answer:

x = 2/5, y= -22/5

Step-by-step explanation:

4x−y=6;3x−2y=10

Step: Solve4x−y=6for y:

4x−y+−4x=6+−4x(Add -4x to both sides)

−y=−4x+6

-y/-1 = -4x +6 over -1 (Divide both sides by -1)

y=4x−6

Step: Substitute4x−6for y in 3x−2y=10:

3x−2y=10

3x−2(4x−6)=10

−5x+12=10(Simplify both sides of the equation)

−5x+12+−12=10+−12(Add -12 to both sides)

−5x=−2

-5x/-5 = -2/5 (Divide both sides by -5)

x=  2 /5

Step: Substitute  2/ 5  for x in y=4x−6:

y=4x−6

y=4 ( 2/ 5 ) −6

y=  −22 /5

(Simplify both sides of the equation)

x = 2/5, y= -22/5
