The GCF of numbers is the greatest common factors between the numbers

The GCF of the years is 1

The intervals are given as: 13 years and 17 years

Factor both intervals (i.e. 13 and 17)

13 = 1 * 13

17 = 1 * 17

The common factor between both products is 1

So, we have:

GCF = 1

Hence, the GCF of the years is 1

2000 pounds is equal to 1 ton

answer: 2000 pounds = 1 Ton

Answer:

  a) h = 6 2/17

  b) k = 3 8/17

Step-by-step explanation:

We can make a list of corresponding sides:

  AB (17 cm) and DE (13 cm)

  BC (15 cm) and EC (8+k cm)

  CA (8 cm) and CD (h cm)

Because the triangles are similar, we know corresponding sides are proportional.

  CD/CA = DE/AB

  h/8 = 13/17

  h = 8(13/17) = 6 2/17

__

  EC/BC = DE/AB

  (8+k)/15 = 13/17

  8 +k = 15(13/17)

  k = 11 8/17 -8 = 3 8/17

Answer:

410

Step-by-step explanation:

20 rows of 12 means there are x amount of people in the 20 rows of 12 seats.

x=20*12

x=240

20 rows of 10 means there are y amount of people in the 20 rows of 10 seats.

y=20*10

y=200

We know that there are 440 seats in the theater. (240+200)

Since 30 chairs are not full, we subtract 440 from 30 and you get 410.

There are 410 people in the theater.

Answer:thethey are 410 persons in the theater

Step-by-step explanation: 20*12=240 and 20*10=200

240+200=440-30=410

Answer:

B. 2.

Step-by-step explanation:

You can find the average by substituting the given values in the function, then  do an arithmetic average with results.

So, for X = - 1 you get f(-1) = 1

For X = 0 you get f(0) = 3

So, the average with 1 and 3 is 2. Because you sum numbers which results 4, and then divided by 2 (the amount of numbers involved in the average).

Answer:

See below.

Step-by-step explanation:

Slope intercept form is y=mx+b, with m being the slope, and b being the y-intercept.

The slope(rise/run) is 1/2. The y-intercept is 5.

Answer:

Step-by-step explanation:

I can't really read or make out what is intended by the choices, but I can give you an answer (I hope).

a = 1

b = 3

c = 3

x1 = (-b +/- sqrt(b^2 - 4ac) )/2a

x1 = (-3 +/- sqrt(3^2 - 4*1*3)) /2(1)

x1 = (-3 +/- sqrt(9 - 12) )/2

x1 = (-3 +/- sqrt(-3) ) / 2

x1 = -1.5 + sqrt(3)*i/2

x2 = -1.5 - sqrt(3)i / 2

Answer:

x = 75

Step-by-step explanation:

Hi there!

Let's start by looking at the two parallel lines, l and m, and the diagonal line that crosses both of them. Line l and this diagonal line create the angle that measures (2x-30)°.

For a second, let's pretend that the 45°, x° and the straight line aren't there. The diagonal line and line m would create the alternate exterior angle of the angle that measures (2x-30)°. (Please see the attached image.)

Alternate exterior angles are equal in measure.

Now, with this knowledge, we now know that (2x-30)° is equal to 45+x:

2x-30 = 45+x

x-30 = 45

x = 75

Therefore, the value of x is 75.

To check your answer, you can substitute x into (2x-30)° and find the angle. It equals 120°. 45+75 is equal to 120°, so therefore, this answer is correct.  

I hope this helps!

Answer:

Solution,

length(l)=27km

Area(A)=212km²

Now As we have,

Area=lxb

212km²=27kmxb

b=212km²/27km

b=7.85km

Step-by-step explanation:

Since we have to divide the area by length to get the width. So, option C is correct.

Answer:

Step-by-step explanation:

One characteristic of a reflection that is useful for answering this question is that it always reverses the clockwise/counterclockwise orientation of a figure. Rotation and translation have no effect on that orientation.

__

1. translation by reflection

Reflection across two parallel lines has the net effect of translating a figure twice the distance between the parallel lines. So, one way to effect a translation using two lines of reflection is to draw one of them through the perpendicular bisector of a point and its translated image. Then the other line would be drawn parallel to the first through the image point.

True: translation can be replaced by two reflections

__

2. translation by rotation

A single point can be moved from one set of coordinates to another by rotating around any point on the perpendicular bisector of the original and its image. To "undo" the change in direction of other points in the image, the image can be rotated an equal angle in the reverse direction about the point that is in its proper place.

That is, if we rotate figure ABC an amount of X° about a point on the perpendicular bisector of AA', so that A ends up at A', then the translation can be finished by rotating that figure by -X° about point A'.

The simplest case is an initial rotation of 180° about the midpoint of AA', followed by another rotation of 180° about A'.

True: translation can be replaced by two rotations

__

3. rotation by reflection

As discussed above, reflection changes orientation and rotation does not.

However, a rotation can be replaced by two reflections. The rotation angle is equal to twice the angle between the lines of reflection. The point where the lines of reflection meet is the center of rotation.

False: rotation can be replaced by reflection

__

4. reflection by rotation and translation

As discussed above, reflection changes orientation, but rotation and translation do not.

False: reflection can be replaced by rotation and translation

Answer:

4D - 1

Step-by-step explanation:

So, if Ted saves $D for 4 weeks, then this amount will be equal to 4D because multiplication is simply repeated addition. We can imagine this situation as D+D+D+D, for the 4 weeks he is saving. We can simplify this to 4D in the expression.

Next, the question tells us that this will be 1 dollar more than needed. So, if we want to find the cost, we need to subtract that dollar.

Thus, the final expression is 4D - 1 because this represents 1 dollar less than the money he saves for 4 weeks.

Answer:

11.  8 mph

12. Yes the rates are equivalent

Step-by-step explanation:

11.

We need to calculate the distance the person would walk in 1 hour.

To do this, multiply both by 24:

1/3 x 24 = 8 miles

1/24 x 24 = 1 hour

Therefore, the person's speed = 8 mph

12.

0.2 km for every 0.5 min

0.8 km for every 2 min

If we multiply both numbers in the first rate by 4 we will get:

(0.2 x 4) km for every (0.5 x 4) min = 8 km for every 2 min

This is the same as the second rate.

Therefore the rates are equivalent (as they are the same)
