Answer:
120 miles
Step-by-step explanation:
Distance in 2nd hour: 40 miles
Distance in 1st hour:
40/(4/3) = 30 miles
Distance in 3rd hour:
(5/4) * 40 = 50 miles
Total distance:
40 + 30 + 50 = 120 miles
Hi!
If you're given a net and measurements like this, then you can take it part by part to figure out the area of all the different shapes you're given and add it all together.
I'm going to first do the two triangles. The two have the same measurements, 6 by 8, and since there are two of them, you can combine the two. The formula for the area of a triangle is 1/2bh, and since there are two, you can make it 2 * 1/2bh. The 2 cancels out with the 1/2, and you just get bh.
The base, I'm just going to set 8 equal as it, and 6 as the height. 8 * 6 = 48, so the area of the two triangles is 48 cm squared.
Now to find the area of the rest. Since they all have a dimension of 15 cm, you can add together their other dimensions, and just multiply it all together.
6 + 8 + 10 = 24 cm
Now just multiply base * height, or 24 * 15. 24 * 15 = 360 cm squared.
Now add the two together. 360 + 48 = 408 cm squared.
Hope this helped!
Step-by-step explanation:
-2x -6 = -2x -2 -4
-2x -6 = -2x -6
Collect like terms
-2x +2x = - 6 +6
0 = 0
From this, you can choose your correct answer
Theoretical probability is the number of desired outcomes (heads) divided by the total number of outcomes (heads or tails). The actual outcome does not affect the theoretical probability. Mark is correct.
60/1 = 60.
The fractions, are:
when simplified by 3, 180/3 = 60
when simplified by 5, 300/5 = 60
when simplified by 2, 120/2 = 60
