Answer:

Step-by-step explanation:

3^-6 × (3^4 ÷ 3^0)^2 = 3^-6 × (3^4 ÷ 1 )^2           {any number raise to zero = 1}

     = 3^-6 × (3^4 )^2

   =  3^-6 × (3^8)             [ (a^m)^n = a^ m*n ]

     = 3^ -6 + 8 = 3^2 = 3 * 3 = 9

Problem 1

The exterior angles sum to 360

9v+(19v-21)+45+(v+48)+7v = 360

36v+72 = 360

36v+72-72 = 360-72

36v = 288

36v/36 = 288/36

v = 8

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

Problem 2

Why is this? because TW is perpendicular to VS (the right angle marker shows this). At the same time, TW cuts VS into two equal pieces, ie VW = WS. The tickmarks indicate the segments are the same length.

x + (4 + x) = 20

2x + 4 = 20

2x = 16

x = 8

Proof

x + (4 + x) = 20

8 + 4 + 8 = 20

12 + 8 = 20

20 = 20

The numbers are 8 and 12.

Final answer:

To find how many text messages, x, Tim sent last month, use the equation: Total cost = fixed cost + variable cost. Given that Tim's phone bill was $30.58, the equation is $30.58 = $25.08 + $0.22x. Solving the equation gives x ≈ 25, so Tim sent approximately 25 text messages last month.

Explanation:

To find the number of text messages, x, Tim sent last month, we can use the equation:
Total cost = fixed cost + variable cost

Given that Tim's phone bill was $30.58, the fixed cost is $25.08. The variable cost is $0.22 per text message sent. Let's represent the number of text messages sent by x.

So, the equation becomes:
$30.58 = $25.08 + $0.22x

To solve for x, we need to isolate x. Subtract $25.08 from both sides of the equation:

$30.58 - $25.08 = $0.22x

Simplify:

$5.50 = $0.22x

Divide both sides of the equation by $0.22:

x = $5.50 / $0.22

x ≈ 25

Therefore, Tim sent approximately 25 text messages last month.

Answer:

For 1 is 1

The equation of line T is 2x - y = 7 ⇒ (6x - 3y = 21)

Step-by-step explanation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size

Line L is mapped onto the line T by a dilation centered at the origin and  a scale factor of 3.

That means lint T is the image of line L after dilation

∵ The equation of line L is 2x - y = 7

∵ Line L is dilated by scale factor 3 and centered at origin

- That means multiply the equation of line L by 3 to find the

   equation of line t

∵ Line T is the image of line L after dilation

∴ The equation of line T is (3)(2x) - (3)(y) = (3)(7)

∴ The equation of line T is 6x - 3y = 21

Very important note:

The equation of line T is the same with equation of line L but multiplied by the scale factor 3 ⇒ L and T are coincide lines (same line)

That means the equation of lines T and L is 2x - y = 7

The equation of line T is 2x - y = 7 ⇒ (6x - 3y = 21)

Final answer:

To determine the total cost of the olive oil, multiply the quantity of 5.6 liters by the price per liter, which is $8.70. The total cost for the restaurant owner is $48.72.

Explanation:

The question asks us to calculate the total cost for a restaurant owner who buys 5.6 liters of olive oil at a price of $8.70 per liter. To find the total cost, we multiply the quantity of olive oil by the price per liter.

Calculation: Total cost = Quantity x Price per liter

Total cost = 5.6 liters x $8.70 per liter

Total cost = $48.72

Therefore, the restaurant owner will pay $48.72 for 5.6 liters of olive oil.

Answer:

Step-by-step explanation:

You want to know Alexandra's arrival time if she started at the same time as Michael (8:00 am) and drove at 45 mph, while Michael drove at 55 mph and arrived at 5:00 pm.

Travel time is inversely proportional to speed, so the time it takes Alexandra to make the trip is 55/45 = 11/9 times what it take for Michael to make the trip.

Michael's travel time from 8 am to 5 pm is 9 hours, so Alexandra's travel time is ...

  (11/9)(9 h) = 11 h

She will arrive 2 hours after Michael does.

Alexandra arrives at 7:00 pm.

Now, the team gained 5 yards on their play of the game.

Hence, the team now has (x + 5) yards on their play of the game.

Next, the team lost 6 yards and finally, the team will have [(x + 5) - 6] = (x - 1) yards in total.

Therefore, the total change in yardage of the team is by - 1 yard. (Answer)

Answer:

The total change in yardage of the team is by - 1 yards.

Step-by-step explanation:

The total change in yardage of the team is by - 1 yards.

First find m<HGC.

m<HGC=14 degrees (through vertical angles)

So...

m<HGE=14+78=92 degrees (through adjacent angles)

Now we have two parallel line cut by a transversal. And so... <HGE and <CEG are same side interior angles which means they are supplements (sum to 180 degrees)

m<HGE+m<CEG=180

92+m<CEG=180

m<CEG=88 degrees

<CEG and <CEB make a linear pair and are thus are supplements as well.

So...

m<CEG+m<CEB=180

88+m<CEB=180

m<CEB=92 degrees

m<CEB=4x=92

x=92/4=23 degrees

answer: 23 degrees

Answer:

3.728 cm²

90

Step-by-step explanation:

To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.  

Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.

So, the length of the patches is [tex]28 \times \frac{1}{12} = 2.33[/tex] m and the width of the patches is [tex]12 \times \frac{2}{15} = 1.6[/tex] m.

Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)

Now, the area of the rectangular piece of material is (28 × 12) = 336 m²

Hence, [tex]\frac{336}{3.728} = 90.37[/tex] ≈ 90 such patches can be made out of the whole material. (Answer)

=420 trees in 3 1/2 hours

There are 420 trees will be sold in three and a half hours.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Every minute, there are two Christmas trees sold at the tree farm.

Now,

Since, Every minute, there are two Christmas trees sold at the tree farm.

Hence, Number of sold Christmas tree in 1 hour = 2 × 60

                                                                          = 120

So, Number of sold Christmas tree in 3 1/2 hour = 120 × 3 1/2

                                                                          = 120 × 7/2

                                                                          = 420

Answer: 1

Step-by-step explanation:

It will be the smallest value for f(x).

The minimum of a sinusoidal function is the lowest point on the graph that is 1.

The minimum of a sinusoidal function is the lowest point on the graph. Looking at the image you provided, the minimum point is the lowest y-coordinate the curve reaches.

Since the graph is a sine wave, it oscillates between a maximum and a minimum value. For a standard sine function, which this graph appears to resemble, these extrema occur at points where the sine of the angle is either 1 or -1.

The minimum value of sine is -1, but the actual minimum value of the function on the graph will depend on any vertical shift and amplitude changes.

To find the exact minimum value from the graph, you'd look for the lowest point on the y-axis that the graph reaches. From the image, it's not perfectly clear, but it looks like the minimum value is around -2 on the y-axis.

This would be the case if the function has no vertical shift from the standard sine wave. If there's a vertical shift, the minimum would be the standard minimum value of sine (-1) plus the vertical shift.
