Coordinates of ∆ABC

  • A(3,-2)
  • B(5,5)
  • C(-4,2)

Now co-ordibates of ∆A'B'C'

\\ \rm\longmapsto A'=(3,2)

\\ \rm\longmapsto B'=(5,-5)

\\ \rm\longmapsto C'=(-4,-2)

Step-by-step explanation:

the formula of coordinates (x, y) that reflected across the x-axis : (x, y) => (x, -y)

so,

A(3, -2) => A'(3, 2)

B(5, 5) => B'(5, -5)

C(-4, 2) => C'(-4, -2)

IM GIVING BRAINLIEST AND 100 POINTS NO JOKE. PLEASE HELP
Sav [38]

Answer:

i hope this helps

Step-by-step explanation:

if you have 100 people in the room and you interviewed all of them, (for number 6). that means that 70% of these people ate breakfast

70% of the total amount of people you interviewed is 70. That means that 70 people you interviewed, eat breakfast.

Then it also says, "of those 70% of people, 25% eat cereal"

That means 25% of those 70 people eat cereal, or 1/4 of that population does.

0.25 * 70 = 17.5. (of course you cannot have part of a person, but this is an example)

and of the 17.5 people, 30% of them eats it with extra sugar.

so 30% of 17.5 people is 5.25.

that means that there are 5.25 people who eat cereal with extra sugar.

i hope this helps, it took a while for me to try to help with this

i noticed that you made a mistake. the amount of people that eat cereal is 25% of 70% of the people. that means you have to find 0.25 of 0.7 <--- (you multiply not divide)

(0.25x 0.7) = 0.175

In the previous problem, how does the angle of depression from the top of the taller building relate to the angle of elevation f
tia_tia [17]
The angles of elevation and depression are formed by the line of sight and the horizontal line. When the line of vision is above the horizontal line, the angle is of elevation, and if the line of sight is below the horizontal, the angle is of depression.

 The angle of depresion from the top of the taller building and the angle of elevation from the top of the shorter building are alternate interior angles. Then, if the angle of depression of the taller building is 15° the angle of elevation of the shorter building is 15° too. To understand this, you should see the diagram attached. 

 In the diagram you can notice that both angles, of elevation and depression, have the same value.

 Then, the answer is: The angle of depresion from the top of the taller building and the angle of elevation from the top of the shorter building are alternate interior angles.

Lexie is making a scale drawing of a soccer field that is 120 yards long and 80 yards wide. If the field in Lexie’s drawing is 3
timurjin [86]

Answer:

  • <em><u>The field in Lexie's drawing should be 20 cm long.</u></em>

Explanation:

Making a scale drawing requires that the figure be similar, which implies that the sides of the figures be proportional.

The proportion for a drawing 30 cm wide and unknown length with the soccer field that is 120 yards long and 80 yards wide is:

  • length of the drawing / width of the drawing = length of the field / width of the field

Thus, using x for the unknown width of the drawing:

  • 30 cm / x = 120 yard / 80 yard

Thus, you must solve for x:

  • 30 cm × 80 yard = 120 yard × x

  • x = 30 cm × 80 yard / 120 yard = 20 cm.

Hence, the field in Lexie's drawing should be 20 cm long.
