Answer:

Kepler-452b has a probable mass five times that of Earth, and its surface gravity is nearly twice as Earth's, though calculations of mass for exoplanets are only rough estimates. If it is a terrestrial planet, it is most likely a super-Earth with many active volcanoes due to its higher mass and density.Step-by-step explanation:

Answer:

$385

Step-by-step explanation:

60% of $875 = $525

$875 - $525 = $350

10% of $350 = $35

$350 + $35 = $385

Answer: 0.0905475920892 miles

Step-by-step explanation:

Convert km to Miles using conversion

1km = 0.6213712 miles

86 x 0.6213712 = 53.4379232 miles/hour

divide that by 60 to get miles per minute. Divide again to get miles per second

53.4379232 / 60 / 60 = 0.0148438675556 miles/second

6.1 x 0.0148438675556 = 0.0905475920892 miles

Answer:

The average rate of change is 7.

Step-by-step explanation:

We are given the function:

[tex]f(x)=2x^2+x+5[/tex]

Which represents the number of jars of pickles, y (in tens of jars), Denise expects to sell x weeks after launching her store.

We want to find the average rate of change over 1 ≤ x ≤ 2.

Essentially, we want to find the slope over f(1) and f(2).

Thus, first evaluate the two endpoints:

[tex]f(1)=2(1)^2+(1)+5=2+1+5=8[/tex]

And:

[tex]f(2)=2(2)^2+2+5=8+2+5=15[/tex]

This gives us the two points (1, 8) and (2, 15).

Then the average rate of change will be the slope between the two:

[tex]\displaystyle m=\frac{15-8}{2-1}=7[/tex]

With units, this means that over the first and second week, Denise sold on average 70 jars of pickles per week.

Then you are able to substitute in X and it can have a infinite number of values catered to the question.

Answer:

3c = t

Step-by-step explanation:

3 cereal boxes is 3c and the total is t. so 3c = t

Answer:

3c = t

3 is the amount of boxes, c is the money, therefore, it is 3c=t, which means c times the number of boxes equals t

Answer:

Step-by-step explanation:

3x - 2y = 2. (1)

9x - 6y = 6. (2)

Multiply equation (1) by 3 and (2) b 1

3x - 2y = 2 → 9x - 2y = 6 (3)

9x - 6y = 6 → 9x - 6y = 6 (4)

The error is equation (3)

It should be 9x - 6y = 6

-8y = 12

y = 1.5

3x - 2y = 2 → 3x - 2(1.5) = 6

3x - 3 = 6

3x = 9

x = 3

3x - 2y = 2

9x - 6y = 6

3x - 2y = 2 → 9x - 6y = 6. (3)

9x - 6y = 6 → 9x - 6y = 6. (4)

9x - 6y = 6 (3)

9x - 6y = 6 (4)

Answer:

Step-by-step explanation:

Answer:

Roses = x = 4

Carnations = y = 12

Daisies = z = 8

Step-by-step explanation:

The bouquet was made up of roses, carnations, and daisies.

Let us represent:

Roses = x

Carnations = y

Daisies = z

Melanie gave her mother a bouquet of 24 flowers.

Hence,

x + y + z = 24...... Equation 1

There were twice as many daisies as roses.

z = 2x

There were three times as many carnations as roses.

y = 3x

Therefore, we substitute 2x and 3x for z and y respectively in Equation 1

x + y + z = 24...... Equation 1

x + 3x + 2x = 24

6x = 24

x = 24/6

x = 4 roses

Solving for y

y = 3x

y = 3 × 4

y = 12 Carnations

Solving for z

z = 2x

z = 2 × 4

z = 8 Daisies

How many of each kind of flower was in the bouquet?

Therefore,

Roses = x = 4

Carnations = y = 12

Daisies = z = 8

Melanie gave her mother a bouquet of 24 flowers which has three kinds of flowers

The number of roses in the bouquet  = 4

The number of carnations in the bouquet  = 12

The number of daises in the bouquet  = 8

Melanie gave her mother a bouquet of 24 flowers.

The  bouquet was made up of roses, carnations, and daisies.

Let there be x roses

Let there be y carnations

Let there be z daises in the bouquet

So the total number of flowers  in the bouquet is given by equation (1)

[tex]\rm x +y + z = 24........(1)[/tex]

There were twice as many daisies as roses.

So

[tex]\rm z =2x ....(2)[/tex]

Also , There were three times as many carnations as roses

[tex]\rm y = 3x ........(3)[/tex]

From equations (1) , (2) (3) we get

[tex]\rm z \; and \; y \; from \; (2)\; and \; (3)\; in\; (1) \; we\; get \\x + 2x +3x = 24\\6x = 24\\x= 24/6\\x = 4[/tex]

So

The number of roses in the bouquet  = 4

The number of carnations in the bouquet  = 12

The number of daises in the bouquet  = 8

Step-by-step explanation:

Leg: 28m

Hypotenuse: 37m

To find the missing leg, use the following formula:

b = √[tex]c^{2} - a^{2}[/tex]

b = √[tex]37^{2} - 28^{2}[/tex]

b = √1369 - 784

b = √585

I uploaded a picture. Does it help??

Answer:

x = 0

Step-by-step explanation:

If the line is parallel to x = 7, it will also be a vertical line.

Vertical lines will only have one possible x-value, and since the line passes through (0, 1), this means the vertical line goes through the x value 0.

The equation of the line will be x = 0

Answer:

It will take 20 minutes  for both buckets to have the same amount of water

Step-by-step explanation:

Let "t" be the time in minutes when both the buckets will fill

The total volume in bucket A after t minutes

[tex]340 + 7t[/tex]

The total volume in bucket B after t minutes

[tex]640-8t[/tex]

It will take 20 minutes  for both buckets to have the same amount of water

Angle O=64

Side m=7.3159882(rounded if needed)

Side n=16.68902(round if needed)

We are given

Angle M which equal 26.

Angle N equals 90 degrees

Side MN which equal 15.

We are asked to find all the missing elements of the triangle.

[tex]90 + 26 + x = 180[/tex]

[tex]116 + x = 180[/tex]

[tex]x = 64[/tex]

Angle O=64 degrees

We can find side m by doing law of sines.

[tex] \frac{on}{ \sin(26) } = \frac{mn}{ \sin(64) } [/tex]

[tex] \frac{on}{ \sin(26) } = \frac{15}{ \sin(64) } [/tex]

[tex]on = \frac{15}{ \sin(64) } \times \sin(26) [/tex]

which is 7.315(round if neeeded).

We can find side n using pythagorean theorem,

[tex] {15}^{2} + {7.3}^{2} = {n}^{2} [/tex]

[tex]225 + 53.29 = {n}^{2} [/tex]

[tex] \sqrt{278.29} [/tex]

Answer:

Each side = 4m-5

Step-by-step explanation:

16m2 - 40m + 25

factor:

(4m - 5)(4m - 5)

Each side = 4m-5

Answer:

The expression for each side = 4m - 5.

Step-by-step explanation:

We need to factor the expression for the area. As the figure is a square both factors should be identical.

16m^2 - 40m + 25:

16m^2 and 25 are both perfect squares so looks like the factors are

(4m - 5)(4m - 5)

The signs are negative because the middle term is - 40m.

If we expand the factors we get:

4m*4m - 5*4m - 5*4m -5*-5

16m^2 - 20m - 20m + 25

= 16m^2 - 40m + 25  which is the original expression, so this confirms our result.

Answer: 84.1m

Step-by-step explanation:

Let the height of the flagpole be represented by x.

First and foremost, we have to know that the cosine of 18° = 0.9511.

The equation to get the height will then be:

0.9511 = 80/x

Cross multiply

(0.9511 × x) = 80

0.9511x = 80

Divide both side by 0.9511

0.9511x/0.9511 = 80/0.9511

x = 84.1

The height of the flagpole is 84.1m

Answer:

(a) The possible dimensions are:

1 unit by 72 units;  2 units by 36 units;  3 units  by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units

(b): Patio with greatest and the least perimeter

The dimension with the greatest perimeter is: 1 by 72

The dimension with the least perimeter is: 8 by 9

Step-by-step explanation:

Given

[tex]Tiles = 72[/tex]

Solving (a): Possible rectangular models

To do this, we simply list out the possible factor pairs of 72.

So, we have:

1 unit by 72 units;  2 units by 36 units;  3 units  by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units

Solving (a): Models with the least and the greatest perimeter

Perimeter (P) is calculated using:

[tex]P = 2 * (L + W)[/tex]

So:

1 unit by 72 units;  

[tex]P = 2 *(1 + 72) = 146 units[/tex]

2 units by 36 units;  

[tex]P = 2 *(2 + 36) = 76 units[/tex]

3 units by 24 units;

[tex]P = 2 *(3 + 24) = 54 units[/tex]

4 units by 18 units;

[tex]P = 2 *(4 + 18) = 44 units[/tex]

6 units by 12 units;

[tex]P = 2 *(6 + 12) = 36 units[/tex]

8 units by 9 units

[tex]P = 2 *(8 + 9) = 34 units[/tex]

From the calculations above:

The dimension with the greatest perimeter is: 1 by 72

The dimension with the least perimeter is: 8 by 9

Step-by-step explanation:

[tex]\frac{2,400}{0.48} = 5,000[/tex]

There are 5,000 students in total.

Since 2,400 of them are female, the remaining students must be male.

5,000 - 2,400 = 2,600 male students

Answer:

72

Step-by-step explanation:

5a = 540            [ all interior angles r equal to 540 as "(n-2)x 180  (Interior                                           ____________________________________________angle poperty )]

a= 540/5 = 108   (one interior angle)

x + a = 180                      (linear pair)

x= 180 - a

x = 180 - 108 = 72

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Another way ::

Sum of Exterior angle = 360                 (exterior angle property)

One exterior angle = x = 360 / 5 = 72        ( 360 by the number of sides )
