Answer:

4 1/8km

Step-by-step explanation:

if you have done 3 1/4km you can multiply the fraction by 2 so you get 3 2/8.

so now we have 2 5/8km and 3 2/8.

(its always easier to have the fractions the same denominator)

now we add the whole numbers first.

2 km + 3km = 5km.

now the fractions.

5/8 km + 2/8 km = 7/8km.

now add them both together and we get.

5 7/8 km.

take that answer away from 10.

we get 4 1/8km.

Final Answer(s)

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.

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

Answer:

3/10

Step-by-step explanation:

So 15/50 and 20/50 are used, so you add them together, which would be 35/50

Then you subtract 35/50 from 50/50 to find what is left, which would be 15/50

Simply that by dividing the numerator and denominator by 5, which the final answer would be 3/10

Answer:

5:45am

Step-by-step explanation:

75-30=45

add the 30 to 4:30

you'll have 45 mins left over, so 5:45

Answer:

He finished at 5:45 am

Step-by-step explanation:

turn 75 minutes also can be said as 1 hours and 15 minutes

so here given that he started at 4 hours and 30 minutes

finished at  =   ( 4 + 1 ) hours     (  30 + 15 ) minutes

                   =  5 hours  :   45 minutes

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:

3

Step-by-step explanation:

volume = height x length x width

Divide the volume by the height and provided side to get the missing side

252/7 = 36

36/12 = 3

Check:

volume = height x length x width

252 = 7 x 12 x 3

252 = 252

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:

  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:

x = -2 and y = -4

Step-by-step explanation:

Given:

2x + y = -8

x - y = 2

Add the two equations:

3x + 0y = -6

3x = -6

x = -2

Sub x = -2 into the second equation

-2 - y = 2

-4 = y

Therefore, x = -2 and y = -4

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).
