ATMOSPHERIC SCIENCE The troposphere extends from the Earth's surface to a height of 6-12 miles, dependin
on the location and the season. If a plane is flying at an altitude of 5.8 miles, and the troposphere is 8.6 miles deep in
that area, how much higher can the plane go without leaving the troposphere?
Answer:
2.8 Miles
Step-by-step explanation:
You subract 5.8 from 8.6 to get the answer.
determina la ecuacion de la recta cuyas intersecciones con los ejes x e y se indican respectivamente A(7,0) Y B (0, -4)
Answer:
y = 4/7 - 4
Step-by-step explanation:
Slope = (-4-0) / (0 - 7) = -4/-7 = 4/7
y-intercept: -4 - (4/7)(0) = -4

Answer:
471.24
Step-by-step explanation:
Answer:
A= 471.24
Step-by-step explanation:
The formula for the surface area of a cylinder is
[tex]A=2\pi rh+2\pi r^2[/tex]
What we know is
Radius = 5 inHeight = 10 inUsing these numbers, we can know plug them into the formula.
[tex]A=2\pi (5)(10)+2\pi(5)^2[/tex]
Simplify
[tex]A= 100\pi + 50\pi[/tex]
[tex]A= 150\pi[/tex]
[tex]A= 471.24[/tex]
If using the method of completing the square to solve the quadratic equation
x2 + 5x – 21 = 0, which number would have to be added to "complete the
square"?
Answer:
Step-by-step explanation:
ax² + bx + c = y
x² + 5x – 21 = 0
First make sure the (a) term = 1... It is.
Get (c) to zero or blank by adding or subtracting as needed.
x² + 5x – 21 + 21 = 0 + 21
x² + 5x = 21
Add the square of half of the b term to each side
x² + 5x + (5/2)² = 21 + (5/2)²
x² + 5x + (5/2)² = 27.25
rewrite the left side as a square
(x + 2.5)² = 27.25
square root of each side
x + 2.5 = ±√27.25
isolate x
x = -2.5 ±√(27.25)
x ≈ 2.72 or -7.72
Answer:
[tex]\frac{25}{4}[/tex] = 6.25
Step-by-step explanation:
x² + 5x - 21 = 0 ( add 21 to both sides )
x² + 5x = 21
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2([tex]\frac{5}{2}[/tex] )x + [tex]\frac{25}{4}[/tex] = 21 + [tex]\frac{25}{4}[/tex]
(x + [tex]\frac{5}{2}[/tex] )² = [tex]\frac{109}{4}[/tex]

In a group of 48 chilldren there are three times as many boys as girls how many girls are there?
Answer:
12 girls
36 boys
Step-by-step explanation:
Answer:12 girls
Step-by-step explanation:
3 Shares boys (Due to it being 3 times more) 1 Share girls
3 Shares boys + 1 Share girls= 4 Shares
48 / 4 Shares = 12
Girls are 1/4 of the 48
so there are 12 girls
what kinds of triangles can you use the pythagorean theorem on
Answer:
Step-by-step explanation:
The Pythagorean theorem applies to right angled triangles only.
However, for any other triangle, by dropping a perpendicular from any vertex on to the opposite side, you form two right angled triangles both of which can be solved by the Pythagorean theorem.
So, the Pythagorean theorem applies to right angled triangles directly and to other triangles indirectly.
9514 1404 393
Answer:
right triangles
Step-by-step explanation:
The Pythagorean theorem relates the side lengths of a right triangle.
c² = a² +b² . . . . . . . . for legs 'a' and 'b' and hypotenuse 'c'
__
Additional comments
The more general form of the relation between side lengths of a triangle is given by the Law of Cosines:
c² = a² +b² -2ab·cos(C) . . . . for sides 'a', 'b', and 'c' with angle C opposite side 'c'
You will notice this reduces to the Pythagorean relation when C = 90°.
__
Triples of integers that satisfy the Pythagorean relation are called Pythagorean triples. The smallest set (and the only sequential set) of these is (a, b, c) = (3, 4, 5). Other triples commonly seen in math problems are (5, 12, 13), (7, 24, 25), (8, 15, 17), and multiples of these.

Answer:
x=1, y=10
Step-by-step explanation:
we use substitution to get from the bottom equation that y=12-2x,
plug that into the first equation to get 5x+12-2x=15
combining like terms and cancelling, we get 3x=3
so x=1,
substituting that into the former equation gives us y=10

Is - 7 a solution of x + 12 = 19?
Answer:
No
Step-by-step explanation:
-7+12=5
Answer:
[tex]x=7[/tex]
-7 is not a solution for [tex]x+12=19[/tex]
Step-by-step explanation:
[tex]x +12 = 19[/tex]
Subtract 12 from both sides
[tex]x = 19-12[/tex]
Subtract 12 from 19 to get 7
[tex]x = 7[/tex]
It would be -7 if it was [tex]-x+12=19[/tex]

Write an equation for each translation of y = |x| .
5.5 units right
A. y = | x | + 5.5
B. y = | x | – 5.5
C. y = | x – 5.5 |
D. y = | x + 5.5 |
Answer:
C. y = | x – 5.5 |
Step-by-step explanation:
y = f(x) + n - moves the graph n units up
y = f(x) - n - moves the graph n units down
y = f(x + n) - moves the graph n units to the left
y = f(x - n) - moves the graph n units to the right
5.5 units to the right
y = f(x - 5.5) = |x - 5.5|

4% ( 3+z)= 6/5
what is z?
Answer:
1/12
Step-by-step explanation:
1/12
Step-by-step explanation:
3/4 + z = 5/6
Subtract 3/4 from each side
3/4 -3/4+ z = 5/6-3/4
z = 5/6 -3/4
Get a common denominator of 12
z = 5/6 *2/2 -3/4 *3/3
z = 10/12 - 9/12
z = 1/12

The cost for a ticket to a play changes based on where
the seat is located. The $225 front-row seats cost three
times as much as a balcony seat. How much do four
balcony seats cost?
$224
$300
$450
$900
Answer:
$300
Step-by-step explanation:
Front row: $225
Front row = 3 * balcony
225 = 3 * balcony
balcony = $225/3 = $75
One balcony ticket costs $75.
4 balcony seats = 4 * $75 = $300
Answer: $300

A rental car agency charges $210.00 per week plus 0.25 per mile to rent a car. How many miles can you travel in one week for $347.00
Answer:
548 miles
Step-by-step explanation:
O.25m + 210 = 347
