Answer: 856.59 km/h

Step-by-step explanation:

Length of a planet's orbit around a star = 17,680,000 km.

Days to complete full orbit = 860 days

Number of hours to complete full orbit = 860 × 24 hours = 20640 hours

The planets average speed in km/h will be:

= Distance / Time

= 17,680,000 / 20640

= 856.59 km/h

Note: 24 hours = 1 day

Answer:

17.28

Step-by-step explanation:

Totall buses: 48+28 = 72

% Of single decker: 72×(24÷100) = 17.28

Approximately 33.33 percentage of the buses in the depot are single-decker buses.

To find the percentage of single-decker buses, we need to calculate the ratio of the number of single-decker buses to the total number of buses (single-decker and double-decker) and then multiply by 100.

The total number of buses in the depot is given as 48 double-decker buses + 24 single-decker buses = 72 buses.

The number of single-decker buses is 24.

The ratio of single-decker buses to the total number of buses is 24 buses / 72 buses = 1/3.

To find the percentage, we multiply the ratio by 100:

(1/3) * 100 = 33.33%

Therefore, approximately 33.33% of the buses in the depot are single-decker buses.

Answer:

  (x +10)(x -4)

Step-by-step explanation:

Compare the factored and expanded forms:

  (x +p)(x +q) = x^2 +(p+q)x +pq = x^2 +6x -40

That is, the constants in the binomial factors will be factors of -40 that have a sum of 6. This is where your knowledge of multiplication tables is helpful.

  -40 = -1×40 = -2×20 = -4×10 = -5×8

The sums of these factor pairs are 39, 18, 6, 3, respectively. So, the one we want is (-4)(10) = -40. Now that we know the values of 'p' and 'q', we can write the factorization ...

  x^2 +6x -40 = (x -4)(x +10)

Answer:

1/6 are oranges bc if half are apples 1/2 and 1/3 is bannas we need to make those fraftions match so we multiply 1/2 by 3 and 1/3 by 2 giving us a fraction over 6 which then we add what we already know so 3/6 is apples and 2/6 is bannas we add them together we get 5/6 which leaves us with 1/6 oranges

The 51 gram of sugar has 204 calorie and there is 62.5 gram of sugar in 250 calories.

A measurement unit is a unit to measure certain quantities.

For example, the mass can be measured in kilograms, length can be measured in meter and time can be measured in seconds.

To find the measurement of a new quantity knows units can be used in operation. As to find the unit for speed we use m/s as a unit, where, m is the unit of distance and s is the unit of time.

Solve these problems using the conversion unit for calorie to gram.

(1) 1 gram = 4 calories

Then, 51 grams = 51 × 4

                         = 204 calories

(2) 4 calorie = 1 gram

    1 calorie = 1/4 gram

    250 calorie = 1/4 × 251

                        = 62.5 gram

Hence, smoothie containing 51 gram sugar has 204 calories and in 250 calories of smoothie there is 62.5 gram of sugar.
