Mr. Jones charged Roberta $32 for parts and $15 per hour for labor to repair her
bicycle. He spent 3 hours repairing her bike. Which expression would be used to
correctly calculate the amount Roberta owes him?

1. 32 x 3 + 15
2. 32 + 3 x 15
3. 3 x 32 x 15
4. 3x(32+15)

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:

[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

Answer:

m∠a = 60° ; m∠b = 30°

Step-by-step explanation:

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

2x + x = 90

3x = 90

x = 30

2(30) = 60

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:

  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

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: 60,000 tiles

Step-by-step explanation:

First find the area of the mural.

= 3 * 2

= 6 m²

The find the area of the tiles.

= 1 * 1

= 1 cm²

I m² = 10,000 cm²

There is therefore:

= 6 * 10,000

= 60,000 cm²

That is the area that needs to be covered in cm²

Seeing as each tile is 1cm², the number of tiles needed is:

= 60,000 / 1

= 60,000 tiles

Answer: the answer is 60,000 tiles

by the way that kinda seems like a lot of tiles to place like how long is that gonna take.
