Mathematics
1 answer:
ValentinkaMS [17]3 years ago
3 0

Answer:

300

Step-by-step explanation:

The rectangles area is 200. (20*10) (though it might be 10*10 because 20 could be the length for it over all but there is the 10 for the triangles side so I think it's just 20).

The triangles area is 100. (1/2*10*20).

Two numbers are in the ratio 3:7
Likurg_2 [28]

Answer:

98 or 18

Step-by-step explanation:

Let's call the numbers 3x and 7x. We have two cases, either 42 is 3x or 42 is 7x. Looking at the first case, if 3x = 42, x = 14 which means the other number is 7 * 14 = 98. Looking at the second case, if 7x = 42, that means x = 6 so the other number is 3 * 6 = 18.

Math study page book <br> show work <br> !!!
GREYUIT [131]

Step-by-step explanation:

for that we use Pythagoras, as the distance is always the baseline (Hypotenuse) of a right-angled triangle created by the x and y coordinate differences between the 2 points.

15.

distance² = (8-3)² + (9-2)² = 5² + 7² = 25 + 49 = 74

distance = sqrt(74) = 8.602325267...

16.

we need to write down the point coordinates first :

(-4, 3)

(1, -3)

distance² = (1 - -4)² + (-3 - 3)² = 5² + (-6)² = 25 + 36 = 61

distance = sqrt(61) = 7.810249676...
