Step-by-step explanation:

The GCF of 30 and 12 is 6

30/6=5

12/6=2

so we can say that...

6(5x-2)

A = 99.84 cm²

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 9.6 and h = 10.4 , then

A = 9.6 × 10.4 = 99.84 cm²

What is an expression for the total cost of feeding h horses?

gogolik [260]

Let's say the cost to feed each horse is $5.00.

The expression would be written as:

(5.00)h or simplified as 5h

This is because you are multiplying the cost for feeding each horse by the amount of horses, represented as h.

If you are feeding 6 horses you would substitute the h for 6 giving you the expression:

5(6)

which equals $30 total.

Hope this helps and have a nice day! :)

Julia rides her horse 18 km with a constant speed of 6km/hr and another 24 km with a constant speed of 12 km/hr. What is her ave

nlexa [21]

Answer:

8.4 km/hr.

Step-by-step explanation:

We have been given that Julia rides her horse 18 km with a constant speed of 6 km/hr.

Let us find the time taken by Julia to cover a distance of 18 km.

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

$\text{Time taken to cover 18 km}=\frac{18\text{ km}}{\frac{6\text{km}}{\text{hour}}}$

$\text{Time taken to cover 18 km}=\frac{18\text{ km}}{6}\times\frac{\text{hour}}{\text{km}}$

$\text{Time taken to cover 18 km}=\frac{18}{6}\times\text{hour}$

$\text{Time taken to cover 18 km}=3\text{ hour}$

We are also told that she rides another 24 km with a constant speed of 12 km/hr.

Let us find the time taken by Julia to cover a distance of 24 km.

$\text{Time taken to cover 24 km}=\frac{24\text{ km}}{\frac{12\text{km}}{\text{hour}}}$

$\text{Time taken to cover 24 km}=\frac{24\text{ km}}{12}\times\frac{\text{hour}}{\text{km}}$

$\text{Time taken to cover 24 km}=\frac{24}{12}\times\text{hour}$

$\text{Time taken to cover 24 km}=2\text{ hour}$

Since we know that $\text{Average speed}=\frac{\text{Total distance}}{\text{Total time}}$ .

Upon substituting our values in above formula we will get,

$\text{Julia's average speed}=\frac{18\text{ km}+24\text{ km}+}{3\text{ hour}+2\text{ hour}}$

$\text{Julia's average speed}=\frac{42\text{ km}}{5\text{ hour}}$

$\text{Julia's average speed}=\frac{8.4\text{ km}}{\text{ hour}}$

Therefore, Julia's average speed is 8.4 km per hour.
