Answer:
15 ≥3.79x
Step-by-step explanation:
We have to spend less than or equal to 15
15 ≥
Each bag costs 3.79
Let x be the number of bags we buy
3.79x
15 ≥3.79x
The first aircraft had 192 seats, the second aircraft had 104 seats and the third aircraft had 88 seats
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let a represent the sits in the first aircraft, b represent the second aircraft and c represent the third aircraft.
The first aircraft has 88 more seats than the second aircraft. Hence:
a = b + 88 (1)
Also, The third aircraft has 16 fewer seats than the second aircraft:
c = b - 16 (2)
If their total number of seats is 384:
a + b + c = 384 (3)
From the three equations:
a = 192, b = 104, c = 88
The first aircraft had 192 seats, the second aircraft had 104 seats and the third aircraft had 88 seats

The slope is -40, and the Y intercept is 83. The equation would be Y= -40x + 83.
Answer:
6.6×10²¹
Step-by-step explanation:
6,600,000,000,000,000,000,000 → there are 21 place values after the first non-zero number ''6''
to convert to standard form, we move the decimal point after the first non-zero number.
<em>6,600,000,000,000,000,000,000</em><em>.</em><em>0 ← decimal in the end</em>
<em>the decimal </em>will be moved, all the digits after the decimal are counted and they will resemble the index.
6.6×10²¹
Answer:
Step-by-step explanation:
*Notes (clarified by the person who asked this question):
-The triangle on the right has a right angle (angle that appears to be a right angle is a right angle)
-The bottom side of the right triangle is marked with a question mark (?)
<u>Triangle 1 (triangle on left):</u>
Special triangles:
In all 45-45-90 triangles, the ratio of the sides is , where is the hypotenuse of the triangle. Since one of the legs is marked as , the hypotenuse must be
It's also possible to use a variety of trigonometry to solve this problem. Basic trig for right triangles is applicable and may be the simplest:
<u>Triangle 2 (triangle on right):</u>
We can use basic trig for right triangles to set up the following equations:
,
We can verify these answers using the Pythagorean theorem. The Pythagorean theorem states that in all right triangles, the following must be true:
, where is the hypotenuse of the triangle and and are two legs of the triangle.
