Answer:

600 watt hours/day

Step-by-step explanation:

We're finding a unit rate here.  Divide 2550 watt-hours by 4 1/4 days (since 6 hours = 1/4 day):

2550 watt-hours

------------------------- = 600 watt hours/day

         4.25 days

Answer:

it is correct but -65 is not correct

Answer:

0.5 < t < 3.5

Step-by-step explanation:

[Given] 64t-16t^2>28

[Rewrite] 64t - 16t² > 28

[Subtract 28 from both sides] 64t - 16t² - 28 > 0

[Reorder] - 16t² + 64t - 28 > 0

[Solve Using The Quadratic Formula] 0.5 < t < 3.5

Answer:

I pretty sure it is F.1cm

Step-by-step explanation:

There are two attachments to this post. The first attachment shows the numbered angles formed through the intersection of the transversal, t, into the parallel lines, m and n, which will be used to determine how each angle relates to other angles.

The corresponding angles in the first attachment are:

∠1 and  ∠5

∠2 and ∠6

∠3 and ∠7

∠4 and ∠8

Corresponding angles have the same measure.

The same-side exterior angles are the pair of angles that are outside the parallel lines, and on the same side of the transversal.  In the first attachment, the same-side exterior angles are:

∠1  and ∠8

∠2 and ∠7

These angles are supplements of each other, meaning that the sum of their measure equal 180°.

Given parallel lines, m and n that are cut by a transversal, t.

The angle that has a measure of  ∠(10x + 5)° is a supplement of ∠(5x + 25)°.  In order to solve for the value of x, we must establish the following equation:

m∠(10x + 5)° + m∠(5x + 25)° = 180°

10x° + 5° + 5x° + 25° = 180°

Combine like terms:

15x° + 30° = 180°

Subtract 30 from both sides:

15x° + 30° - 30° = 180° - 30°

15x° =  150°

Divide both sides by 15:

15x°/15 = 150°/15

x = 10°

Verify whether we have correct value for x by substituting its value into the established equation:

m∠(10x + 5)° + m∠(5x + 25)° = 180°

10(10)° + 5° + 5(10)° + 25° = 180°

100° + 5° + 50° + 25° = 180°

180° = 180° (True statement).

Therefore, we have the correct value for x = 10°.

m∠(10x + 5)°  = 105°

m∠(5x + 25)° = 75°

Answer:

See answer below.

Step-by-step explanation:

1. Start at point (0,0), This point is where the x-y-axis meet.  Do not put a dot

   there because this is your starting point.

2.  Move to the left over to point -1 3/4 . This place is between -1 and -2, and

     closer to -2 because the point is -1 .75.  Remember this point is not on the

     graph.  

3.  Now move up from that point to 4.5 and put a dot at that place.  The point is in the Q II ,  to the left top.  

Answer: Length = 25, width = 7

Step-by-step explanation:

Let width be w, and length be 3w + 4.

Perimeter of a rectangle = 2l + 2w

                                 64  = 2(3w + 4) + 2w

                                 64  = 6w + 8 + 2w

                                 64  = 8w + 8    [subtract 8 from both side]

                                 56  = 8w          [Divide 8 from both side]

                                  w   = 7

Plug w in l, where l = 3w + 4 = 21 + 4 = 25

Answer:

Aaron earns $1.3 per hour more than Peyton

Step-by-step explanation:

Aaron's income is represented by y=29.8x

x represents the number of hours worked

Given that Peyton earns 627 in 22 hours. We want to know how much Aaron earn in 22 hours. We then substitute 22 into the equation as x.

y = 29.8(22)

y = $655.6 in 22 hours

This means that Aaron earns $655.6 in 22 hours.

Therefore, Aaron earns 28.6 dollars more in 22 hours.

We want to know the rate per hour so we divide 28.6 by 22.

rate per hour = 28.6/22

rate per hour = $1.3

Therefore, Aaron earns $1.3 per hour more than Peyton.

Answer:

1f 2×4 -3׳ 12k is divided by × - 3 the remainder is 21 find the value of k

Answer:

x = -21

Step-by-step explanation:

Words : Five more than one-third of a number = -2

Algebraic Equation: 5 + (1/3)x = -2

5 + (1/3)x = -2      [tex]\longmapsto\\[/tex]    Subtract 5 from both sides

5 + (1/3)x - 5 = -2 - 5

(1/3)x = -7     [tex]\longmapsto\\[/tex]     Multiply All sides by 3

(1/3)x * 3 = -7 * 3

x = -21

5 + (1/3)-21 = -2

5 + -7 = -2

-2 = -2

-Chetan K

Step-by-step explanation:

y = -5x/8 + 6

8y = 8 × (-5x/8 + 6)

8y = -5x + 42

5x + 8y = 42

5x + 8y = K, k element real

Option → D

The equation for parallel line is 5x + 8y = 32.

The correct option is (D).

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Equation: y = -5/8x + 6

Now, the parallel line to above equation must have the slope same as the given equation i.e., -5/8.

Then, writing the equation in slope intercept form

A) 8x + 5y = 10

5y= 10 - 8x

y= 10/5 - 8x/5

y= -8/5x + 2

B) 8x - 5y = 15

-5y= 15 - 8x

y= 8/5 x + 3

C) 8y - 5x = -24

8y= -24 + 5x

y= -24/8 +5/8x

y= +5/8x - 3

D) 5x + 8y = 32

8y= 32 -5x

y= -5/8x + 4

Hence, the equation for parallel line is 5x + 8y = 32.

According to the average, it will take you almost 6 hours to do the climb, therefore it will be possible.

Since Jeremy has heard a lot of people in the club talking about tackling a 950-foot rock formation, and he has set a limit that they won't climb anything that takes longer than 7 hours, so they have enough time to travel to and from the place, to determine if it will be possible to climb a 950-foot rock formation within Jeremy's time constraint, the following calculation must be performed, through cross multiplication, to obtain the average rise time:

Therefore, according to the average, it will take you almost 6 hours to do the climb, therefore it will be possible.
