What is,the answer to this problem

Answer 1

Answer:
The key here is to remember that if the figures are "similar", then
each pair of corresponding sides has the same ratio. In both problems,
the pair of figures is similar. (It says so twice on the sheet.)

For the triangle in #1):

-- One pair of corresponding sides is 15yd and 9yd.
-- Their ratio is 15/9 = 5:3 .

-- The other pair of corresponding sides is 20yd and 12 yd.
-- Their ratio is 20/12 = 5:3 .

-- For each pair of corresponding sides, the one in the small triangle
   is 3/5 the size of the corresponding side in the big triangle.

-- The last pair of corresponding sides is 30yd and 'x' .
-- Their ratio is 5:3 .   'x' is 3/5 of 30yd.

For the quadrilateral in #3):
The figures are not both in the same position.
Compared to the smaller one, the bigger one is rotated
almost halfway around to the right.
The smaller one has the shortest side on the bottom, but
the bigger one has the shortest side almost on top.
So you have to be very careful about deciding which side of the
big one and which side of the small one are corresponding sides.
But the question does tell you that the drawings are 'similar', so
you know that each pair of corresponding sides has the same ratio.

-- One pair of corresponding sides is 12in (top of the big one)
      and 4in (bottom of the small one).
-- Their ratio is 12/4 = 3 .

-- Another pair of corresponding sides is 30in and 10in .
-- Their ratio is 30/10 = 3 .

-- Another pair of corresponding sides is 36in and 12in .
-- Their ratio is 36/12 = 3 .

-- For each pair of corresponding sides, the one in the small figure
   is 1/3the size of the corresponding side in the big figure.

-- The last pair of corresponding sides is 48in and 'x' .
-- Their ratio is 3 .  'x' is 1/3 of 48in .

describe what you can do when solving an inequality to assure that the coefficient of the variable term will be positive

Answers

If the coefficient is positive, then just multiply or divide by the same coefficient.
2X less than or equal to 8
divide by 2 throughout to get X is less than or equal to 4

If the coefficient is negative, then multiply or divide by the negative sign and the same number throughout
-2X is less than or equal to 8
divide by -2 throughout to get
X is GREATER THAN OR EQUAL to 8.
Remember the sign changes when you divide or multiply by negative.

Are the ratios 3/5 and 9/15 proportional?How do you know?

Answers

Yes. 5*3=15 and 3*3=9. They are proportional because if you multiply the top and the bottom of the first fraction by the same number and you get the second number they are proportional.

The distance between Hadley and Greenville is 13 miles less than the distance between Parker and Greenville. Write two equations that compare the distance between Parker and Greenville. Tell what your variable represents. Distance between Greenville and nearby Towns (Miles):

Parker: 29
Hadley: ?

Answers

Answer: $x=y+13\nor\ x-y=13$

Here 'x' represents the distance between Hadley and Greenville and 'y' represents the distance between Parker and Greenville.

The distance between Hadley and Greenville =42 miles

Step-by-step explanation:

Let the distance between Hadley and Greenville be x and the distance between Parker and Greenville be y.

Then according to the question,

$x=y+13\nor\ x-y=13$

If the distance between Parker and Greenville = 29 miles

Then substitute the value of y=29 in the above equation, we get

$x=29+13\n\Rightarrow\ x=42$

⇒ The distance between Hadley and Greenville =42 miles

x= Hadley
y= Parker
z= Greenville

segment xz - 13 = segment zy

segment xz = segment zy + 13

Segment zy = 29 miles

Therefore...
segment xz = 29+ 13
Segment xz= 42
Distance from Hadley to Greenville is 42 miles

Answer:

40.6 units

Step-by-step explanation:

Arc length is given by the formula ...

s = rθ

where θ is the measure of the central angle in radians.

There are 2π radians in a circle (360°), so π radians in 180°. That can be used to convert the central angle ADB to radians for use in the formula.

∠ADB = 360° -194° = 166°

∠ADB = 166° = (166/180)π radians = 83π/90 radians

Then the arc length AB is ...

length AB = (14)(83π/90) ≈ 40.561 units

The length of arc AB is about 40.6 units.

How do you solve 5 is _____ % of 25

Answers

Let the missing % be x.

Now, according to your question ;

5 = x% of 25

5 = x / 100 * 25

thus, 25x = 500

Thus, x = 500/25

= 20

Thus, 5 is 20% of 25.

Just put 5 over 25 and then simplify to get 1/5. Now put that into a decimal (.2) then put that decimal into percent form, 20%
