Answer:

  a) none

  b) vertical through the middle

  c) horizontal through the middle

  d) none

Step-by-step explanation:

a) A repeated asymmetrical pattern rarely has a line of symmetry. (I can't think of a case where it does.)

__

b) This figure has left-right symmetry about its centerline. (In general, a light bulb will not, because the screw threads are asymmetrical.)

__

c) Each of the letters is symmetrical about its horizontal centerline, so  the word is as well.

__

d) The letter S is symmetrical about its center point, but not about any horizontal or vertical line. This word is not symmetrical about any line.

__

calculate the time taken for a train to travel 1000m if its initial is 3 m/s and it is moving at a constant acceleration of 0.1m
Anna [14]

Answer:

Step-by-step explanation:

For obects already in motion, the distance travelled, s, is:

s = vi*t + (1/2)at^2

where vi is the initial velocity, a is the acceleration, and t is the time in seconds.

We want the time, t, to reach 1000 meters.

1000 m = (3 m/s)*t + (1/2)*(0.1m/s^2)*(t^2)

(1/2)*(0.1m/s^2)*(t^2) = 0.05t^2

0.05t^2 + 3t -1000 = 0

Solve quadratic equation:

t = 114.6 seconds

What is the slope of the line that passes through points (1,7),(10,1)
astra-53 [7]
Answer:
slope = -2/3

Explanation:
Slope of line can be calculated using the following formula:
slope = \frac{y2-y1}{x2-x1}

We are given:
point (1,7) representing (x1,y1)
point (10,1) representing (x2,y2)

Substitute with the givens in the above formula to get the slope as follows:
slope = \frac{1-7}{10-1} = -2/3

Hope this helps :)

A hat is on sale for h dollars. The regular price is 7 times as much. Charlie has enough money to buy two hats at the regular pr
Nostrana [21]

Answer:

Charlie can buy 14 hats at the sale price

Step-by-step explanation:

Let

h ----> the sale price of the hat

x ---> the regular price of the hat

we know that

x=7h ----> equation A

so

Two hats at the regular price  is equal to multiply 2 by x

Multiply by 2 equation A both sides

2x=(7h)*2

2x=14h

2 hats at the regular price cost the same that 14 hats at the sale price

therefore

Charlie can buy 14 hats at the sale price
