64 ducks in the pond, You remove 7 from 43 since it is asking you how many it were from the start and the seven came after 28 of them flew away. so then it leaves you with 36 ducks, so then you do 28+36=64

The measure of the first angle in a right triangle is 10 less than the measure of the second angle.The third angle is the right
prohojiy [21]
Triangle angles add up to a total of 180 degrees.

X will substitute for the second angle.

(X - 10) will substitute for the first angle, which is 10 less than the second angle (x).

The third angle is a right angle which is 90 degrees.

The equation therefore, the summation of the angles:
90 + x + (x - 10) = 180

Join like terms:
80 + 2x = 180

Solve for x:
2x = 100
x = 50

This means that:
The second angle is 50.
The first angle is 50 - 10 which is 40.

We can double check by adding the angles 50, 40, and 90 together to get 180.

The scale of a map is 1 inch: 250 miles. City A is 378 miles from City B. To the nearest tenth, how far is its distance on the m
juin [17]
This is a proportion question. We can express this as an equation where the answer is x:

\frac{1}{250} = \frac{x}{378}

From there, you can just cross-multiply and divide to get:

\frac{1 * 378}{250}

A tenth of 250 is 25, so this is roughly \frac{375}{250} or \frac{17}{10}, so it'll be approximately 1.7 inches on the map.
