Answer:

The ladder is 8 feet high up on the wall.

Step-by-step explanation:

Let the height up of the ladder on the wall be represented by h. The ladder leaning on the wall, wall and distance of the foot of ladder from the wall form a right angled triangle.

So, applying the Pythagoras theorem;

[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj 2/^{2}[/tex]

[tex]/10/^{2}[/tex] = [tex]/6/^{2}[/tex] + [tex]/h/^{2}[/tex]

100 = 36 + [tex]h^{2}[/tex]

so that,

[tex]h^{2}[/tex] = 100 - 36

   = 64

⇒ h = [tex]\sqrt{64}[/tex]

      = 8 feet

The ladder is 8 feet high up on the wall.

Answer:

The ball's speed is 57.5 m/s

Step-by-step explanation:

Given;

distance between the tee and the green, d = 230 m

time taken for the ball to travel from the tee to the green, t = 4 seconds

The speed of the ball is given as;

speed = total distance traveled / total time taken

speed = 230 m / 4 s

speed = 57.5 m/s

Therefore, the ball's speed is 57.5 m/s

Answer:

3/2

Step-by-step explanation:

Step 1

Multiply the denominator by the whole number

2 × 1 = 2

Step 2

Add the answer from Step 1 to the numerator

2 + 1 = 3

Step 3

Write answer from Step 2 over the denominator

3/2

Answer:

1. You can look at side measurements. Angle measurements will not change so do not use them as reference. For example, if a rectangle has one side as 7 and the other 3, then the scale factor of a rectangle with a side of 21 and 9 would be 3, because 21÷7 is 3 or 9÷3 is 3.

2. You can determine a polygon is similar by having the same angles and/or similar sides.

3. All you need is one side and one angle if the angle and side are opposit each other, so a and A or b and B or c and C. If this is not represented in a problem then you can use 2 angles and 1 side or 1 angle and 2 sides to figure out if they are similar.

That graph in the picture is not linear

Step-by-step explanation:

The graph does not go up or go down the same each unit

Answer:

not linear

Step-by-step explanation:

if it was linear there would be a diagonal straight line.

linear indicates there is a consistent ratio of x values and y values.

Answer:

3.2 cm on map represents 80 kilometers of actual distance.

Step-by-step explanation:

It is given that the scale is:

1 cm = 25 km

And we have to find the distance that will be represented by 3.2 centimeters of length on the map.

Let x be the number of kilometers represented by 3.2 cm

[tex]\frac{1}{25} = \frac{3.2}{x}\\x = 3.2 * 25\\x = 80[/tex]

Hence,

3.2 cm on map represents 80 kilometers of actual distance.

Hello!

Answer: A real life example would be if you would add 100 dollars in a bank account and then, subtract the 100 dollars from that account.

The equation used would be 100 + (-100) or in a simpler version 100 - 100 (They both mean the same thing!)

Hope this helps! :)))

Answer: the answer is linear

Step-by-step explanation: (not sure what functions it’s talkin about but it is linear)

Answer:

20 degrees

Step-by-step explanation:

in order for them to be parallel, the alternate interior angles must be congruent

x+20=2x

therefore x=20
