Answer:

[tex]387\ \text{minutes}[/tex]

Step-by-step explanation:

The time Gavin has is [tex]6\dfrac{9}{20}\ \text{hours}[/tex]

[tex]6\dfrac{9}{20}=\dfrac{20\times 6+9}{20}[/tex]

[tex]=\dfrac{129}{20}\ \text{hours}[/tex]

[tex]=6.45\ \text{hours}[/tex]

[tex]=6\times 60+0.45\times 60=360+27[/tex]

[tex]=387\ \text{minutes}[/tex]

The number of minutes is [tex]387\ \text{minutes}[/tex].

Answer:

y=5/4x

Step-by-step explanation:

The equation for the line passing through points (0, 0),(4, 5), and (8, 10) is; y = (5/4)x

From the coordinate, (0, 0), we can conclude that the y-intercept of the line is 0.

In essence, to determine the equation of the line, we must evaluate the slope by consider two points on the line namely;

Slope, m = (y2 -y1)/(x2 - x1).

Slope, m =( 10 - 5)/(8-4)

Therefore, the equation of the line is;

Answer:

m∠a = 60° ; m∠b = 30°

Step-by-step explanation:

They are complementary angles meaning they have a sum of 90°.

Answer:

5 miles/hour

Step-by-step explanation:

the distance is the length of the track which is given as 1/4 of a mile. she completes each lap in 1/20 of an hour so divide the distance by the time taken to go around the distance

Answer:

Elena's speed is 5 miles/hour

Step-by-step explanation:

The speed is defined as the covered distance per unit time. The distance covered is the length of the circular track which is given as  of a mile. We also know that she completes each lap in of an hour. To get her speed, we have divide the distance covered by the time taken to cover this distance and you come out with 5. She can run 5 miles each hour. Or in other words you take 20 divided by 4 you get 5

Answer:

1/6x

Step-by-step explanation:

the slope intercept form is: y = mx + b

m = slope

b = y-intercept.

When you already have in the form the slope is where m is, so the number that's is with x. In this case it's 1/6x.

Answer:

x = 98 degrees

Step-by-step explanation:

A heptagon has a total of 900 degrees for the interior angles. Add up all the angles and then subtract from 900 to find x.

146+122+142+140+110+142 = 802.

900-802 = 98

Answer:

x = 98

Step-by-step explanation:

This shape has 7 sides. Using the formula n - 2 we can get the number of triangles. n represents the number of sides.

n - 2 = 5

All triangles have 180 degrees, so multiply 180 by the number of triangles (5).

180 × 5 = 900

The total number of degrees in this shape is 900. Adding the other angle measures and then subtracting them from 900 gives us x.

146 + 122 + 142 + 140 + 110 + 142 = 802

900 - 802 = 98.

x = 98

Answer:

[tex]Weight = 6.3 kg[/tex]

Step-by-step explanation:

Given

[tex]Total = 8.4kg[/tex]

[tex]Pears = \frac{1}{4}[/tex]

Required

Determine the weight of apples

First, we calculate the fraction of apple.

[tex]Apple = 1 - Pears[/tex]

[tex]Apple = 1 - \frac{1}{4}[/tex]

Take LCM

[tex]Apple = \frac{4-1}{4}[/tex]

[tex]Apple = \frac{3}{4}[/tex]

The weight is then calculated as:

[tex]Weight = \frac{3}{4} * Total[/tex]

[tex]Weight = \frac{3}{4} * 8.4kg[/tex]

[tex]Weight = \frac{3* 8.4kg}{4}[/tex]

[tex]Weight = \frac{25.2kg}{4}[/tex]

[tex]Weight = 6.3 kg[/tex]

Hence, the apples weigh 6.4kg

9514 1404 393

Answer:

  970

Step-by-step explanation:

It turns out that the radical terms cancel, so the result is an integer. You can find the integer value using your calculator. It is ...

  (5 +2√6)³ +1/(5 +2√6)³ = 970

_____

The cube of 'a' is ...

  (5+2√6)³ = 5³ +3·5²·2√6 +3·5·(2√6)² +(2√6)³

  = 125 +3·50√6 +3·120 +48√6

  a³ = 485 +198√6

The reciprocal of this is ...

  b³ = 1/a³ = 1/(485 +198√6) = (485 -198√6)/(485² -6·198²) = (485 -198√6)/1

  b³ = 485 -198√6

Then the sum is ...

  a³ +b³ = (485 +198√6) +(485 -198√6) = 970
