Answer:

x=2 2/5 years or 2.4 years.

Please mark me as Brainliest  if I am right.

Step-by-step explanation

Equation for each:

Type A: h=36+15x

Type B: h=48+10x

Use substitution:

36+15x=48+10x

5x=12

So your answer would be:

x=2 2/5 years or 2.4 years

What is the length of a 50-inch TV that has a width of 27 inches?
drek231 [11]

Answer:

42.08inches

Step-by-step explanation:

Given data

SIze of TV= 50 inch

Width= 27inches

Length= ??

Applying Pythagoras theorem

z^2= x^2+y^2

50^2=  x^2+27^2

square root both sides

50^2= x^2+27^2

2500= x^2+ 729

2500-729=x^2

1771=x^2

x= √1771

x= 42.08

Hence the lenght is 42.08inches

Kari is flying a kite. She releases 50 feet of string. What is the approximate difference in the height of the kite when the str
MakcuM [25]

Answer:

Step-by-step explanation:

The string of a kite forms a right angle triangle with the ground. The length of the string represents the hypotenuse of the right angle triangle. The height of the kite represents the opposite side of the right angle triangle.

To determine the height of the kite, we would apply the sine trigonometric ratio which is expressed as

Sin θ = opposite side/hypotenuse.

1) if the kite makes an angle of 25° with the ground, then the height, h would be

Sin 25 = h/50

h = 50Sin25 = 50 × 0.4226

h = 21.1 feet

2) if the kite makes an angle of 45° with the ground, then the height, h would be

Sin 45 = h/50

h = 50Sin45 = 50 × 0.7071

h = 35.4 feet

The approximate difference in the height of the kite is

35.4 - 21.1 = 14.3 feet

Lost as usual yep I am
denpristay [2]

Answer:

  y = -3x -4

Step-by-step explanation:

A perpendicular line has a slope that is the negative reciprocal of that of the given line. When the equation starts out in standard form, a line with negative reciprocal slope can be written by swapping the x- and y-coefficients and negating one of them.

The given x- and y-coefficients have the ratio 1:-3, so we can use the coefficients 3 and 1 for our purpose.

The usual process of making the line go through a given point can be used. That is, we can translate the line from the origin to the desired point by subtracting the point coordinates from x and y. Then we have ...

  3(x+3) +(y-5) = 0

__

This is "an" equation. It is in no particularly recognizable form. It can be rearranged to the form y = mx + b:

  3x +9 +y -5 = 0 . . . . . eliminate parentheses

  y = -3x -4 . . . . . subtract terms that are not "y"

B; 25.65+13.23+6.35=45.23

To do this mentally just add the 2 decimals places together first (1.23). Then just add the whole numbers (44). Then add the 2 numbers together, 44+1.23=45.23
