Answer:

1/20

Step-by-step explanation:

3/10 - 1/4

First, convert the fractions to a common denominator:

3/10 *2/2 = 6/20

1/4 * 5/5 = 5/20

Now put them back into the equation and solve:

6/20 - 5/20 = 1/20

Another way to do this:

3/10 - 1/4

Convert the fractions into decimals:

3/10 = 0.3

1/4 = 0.25

substitute back into the equation and solve:

0.3 - 0.25 = 0.05

convert back into fractions:

0.05 = 1/20

Answer: 1/20

Step 1: First, you must change the fractions into a common dominator.

Example:


3 x 2 5 1 x 5 6
—- = —- — = —
10 x 2 20 4 x 5. 20


Now, put them back into the equation and solve to find the answer

Example:

6 5 1
— — — = —
20 20 20


Therefore your answer would be 1/20 ( can not reduce to lowest term)

PLEASE HELP :) LOTS OF POINTS + BRAINLY

Jackson's method to figure out the height of the mountain is from the

similar triangles formed by the light using the mirror.

Response:

  • The height of the mountain is <u>50 feet 8 inches</u>

<h3>Which methods can used to find the height of the mountain?</h3>

The given parameters are;

Distance of the mirror from Jackson = 5 feet

Distance of the mirror from the base of the mountain = 40 feet

Height of Jackson = 6'4'' tall

Required:

The approximate height of the mountain, <em>h</em>

Solution:

The triangles formed by the light from the top of the mountain which is

reflected to Jackson from the mirror, Jackson's height, the height of the

mountain, and their distances from the mirror, are similar triangles.

The ratio of corresponding sides of similar triangles are equal, therefore,

we have;

\dfrac{Jackson's \ height}{Jackson's \ distance \ from \ the \ mirror } =\mathbf{ \dfrac{Height \ of \ the \ mountain}{Distance \ of \ the \ mountain \ from \ the \ mirror}}

Which gives;

\dfrac{6\frac{1}{3} \, ft.}{5 \, ft.} = \mathbf{ \dfrac{h}{40 \, ft.}}

h = 480 \, in. \times \dfrac{76 \, in.}{60 \, in.} = 608 \, in. = \mathbf{50 \frac{2}{3} \, ft. = 50 \, feet \ 8 \, inches}

  • The height of the mountain is approximately <u>50 feet 8 inches</u>

4) If C, P, and T are the midpoints of the sides
marin [14]

Answers:

  • AE = 26
  • AN = 58
  • CT = 22.5
  • Perimeter of triangle AEN = 127

=========================================================

Work Shown:

Because points C, P, and T are midpoints of the sides of triangle AEN, this means the segments CP, PT, and CT are midsegments of triangle AEN.

The segment PT = 13 is a midsegment of the larger triangle, and it is parallel to the side AE. Recall the midsegment is half as long as its parallel side.

This means,

PT = (1/2)*AE

2*PT = AE

AE = 2*PT

AE = 2*13

AE = 26

---------------

We'll use the same idea to find AN

CP = (1/2)*AN

2*CP = AN

AN = 2*CP

AN = 2*29

AN = 58

---------------

And we can also say,

CT = (1/2)*EN

CT = (1/2)*43

CT = 22.5

----------------

Add up the sides of triangle AEN to find its perimeter

Perimeter of triangle AEN = (AE)+(EN)+(AN)

Perimeter of triangle AEN = (26)+(43)+(58)

Perimeter of triangle AEN = 127
