Answer:

2 hours and 24 minutes

Step-by-step explanation:

2 hours at 60 km/h means you have travelled 2*60=120 km

120 km at 50 km/h takes 120/50 = 2.4 hours

2.4 hours is 2 hours and 0.4*60 = 24 minutes.

Doss [256]

Answer:

36

Step-by-step explanation:

Let's call the # of boys and girls 5x and 3x respectively. We can write:

5x = 3x + 24

2x = 24

x = 12 so the # of girls = 12 * 3 = 36

George had 1 sheet of paper.He cuts it into 6 inches by 5 inches,and 3 inches by 6 inches.What were the dimension and total area
7nadin3 [17]

Answer:

A. 8 inches by 6 inches.

B. 48\text{ inches}^{2}.

Step-by-step explanation:

We have been given that George had 1 sheet of paper. He cuts it into 6 inches by 5 inches and 3 inches by 6 inches.

We can see that two dimensions of small parts of paper sheet have one dimension same (6 inches), therefore, one dimension of original sheet of paper will be 6 inches.

We can figure out second dimension of original paper sheet by adding the lengths of dimension other than 6. So the second dimension will be 8 inches (5+3).              

Therefore, the dimensions of our original sheet will be 8 inches by 6 inches.

Now let us figure out the total area of the original sheet of paper by multiplying 8 by 6.

\text{The total area of the original sheet of paper}=8\text{ inches}\times 6\text{ inches}

\text{The total area of the original sheet of paper}=48\text{ inches}^{2}

Therefore. the area of original sheet of paper will be 48\text{ inches}^{2}.

Solve for both x and y value for each angle please
olga_2 [115]
X = 25, y = 14.

This is possible to solve because the vertical angles (7y and 5y + 28 ; 3x +7 and 4x - 18) are equal to each other. To solve for x, just set the two x equations equal to each other. The same is done for y with the y equations.
