Answer:
about 21.3
Step-by-step explanation:
I found the hypotenuse value by doing the Pythagorean theorem.
a^2+b^2=c^2.
"a" and "b" are the values of the legs, and "c" is the value of the hypotenuse. So, "a" is 14 and "b" is 16.
14^2+16^2=c^2
196+256=452.
Now, I found the square root of 452. The square root of 452 is 21.26029163. This value rounded to the nearest tenth is 21.3.
In conclusion, the length of the hypotenuse rounded to the nearest tenth is 21.3 inches.
Speed = dis / time
let plane speed in still air is X and air speed Y
so, X-Y = 2280/4 = 570 km/h
and X+Y = 6650/7 = 950 km/h
so, X = (570 + 950) / 2 = 760 km/h
and Y = 950- 760 = 190 km/h

Answer:
C: x = 7
Step-by-step explanation:
The easiest way to do this is to simply try all of the x-vales given as options.
Option 1: x = -1
Since
, we'll use the first equation.

As we can see, g(-1) is not -4.
Option 2: x = 3
Since
, we'll use the 2nd equation.

Not -4.
Option 3: x = 7
Since
, we'll use the 3rd equation.

Tada! We have found a number such that g(x) = -4, it is 7. Since we only need to find a number, not all numbers, we don't have to check the last option. However, if you're curious:
Option 4: x = 4
Since
(less than <em>or equal to</em>), we'll use the 3rd equation.

1. noun- name of people, places, animals, ideas.
2. gender- what sex you are; male, female
3. number- numbers are things in math that are used to count, for example; 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 etc.
4. Definite article- the word <u><em>the</em></u><em> </em>used before a noun.
4/20 students say S.S. is their favorite
75% say PE is their favorite
you need to get them in the same conditions, one is fraction, and one is percent
4/20= ?% /100 4 __ cross multiply on paper
20 100
4x100= 400/20=20
20% say s.s. is their favorite
20% is smaller than 75%
expresson: 4
20< 75%
