150-25=125mph
130-25=105
This means it was going 125mph and that it dropped an altitude of 25 degrees because of the wind and the slow down of the helicopter
Answer:
103.67 in³
Step-by-step explanation:
given Volume of cone is 1/3 * π * r² * h
here given r = 6/2 = 3 , height = 11 inch
using the formula = 1/3 * π * 3² * 11
=103.67 in³ or 33π in³
Answer:
y =3x - 5
Step-by-step explanation:
Well one of the way to do this question is the formula given below your question, but for me, i rather do it this way
OK they gave u y=3x - 12
And they say another line is parallel, once u see the word parallel means they have the same angle, same slope, same gradient ( sorry if I give u the wrong terms, since I learn mine in Malay)
So first u got to understand the slope-intercept form
y = mx + c
y is your y coordinate
x is your x coordinate
m is your gradient ( as in how much the line slants)
c is the y - intercept, as in, if u draw a graph, the y-coordinate where your line touches the y-axis (the vertical line)
So since the say the both lines are parallel, so both of their "m" is the same that is 3. Why? Cuz just compare
y = mx + c
y = 3x - 12
Therefore the m is 3
Therefore u alredy got your first value, so put it in your slope intercept form
y = mx + c
y = 3x + c
Now how to find c? Very easy, just put in the value of y and x from the coordinate ( that the line youre finding is on) they gave u, just put the value in
They gave u
(1, - 2)
So when x = 1, y = - 2
Therefore put it in
y = 3x + c
-2 = 3 (1) + c
c = - 5
Since now u have your m and c value, your slope intercept form is done, just put it in
y = mx + c
y = 3x + (-5)
y = 3x -5
Answer:
Always
Step-by-step explanation:
Suppose you have triangle ABC with side lengths a, b, c. Suppose that is similar to triangle DEF with side lengths d, e, f.
Now, let k be the ratio of corresponding sides ...
k = d/a
Because the same factor applies to all sides, we also have ...
k = e/b = f/c
That is, if we multiply by the denominators of each of these fractions, we get ...
The perimeter of ΔABC is ...
perimeter(ABC) = a + b + c
The perimeter of ΔDEF is ...
perimeter(DEF) = d + e + f = a·k + b·k + c·k
perimeter(DEF) = k(a + b + c) = k·perimeter(ABC)
k = perimeter(DEF)/perimeter(ABC)
That is, the perimeters are in the same ratio as corresponding sides.
Cost of painting is GHe 109,320
<u>Given:</u>
Floor measure = 15 m by 8 m
Cost of carpeting = GHe 890 per square meter
Total cost of painting and carpeting = GHe 216,120
<u>Find:</u>
Cost of painting
<u>Computation:</u>
Area of floor = 15 × 8
Area of floor = 120 square meter
Cost of carpeting = 120 × 890
Cost of carpeting = GHe 106,800
Cost of painting = Total cost of painting and carpeting - Cost of carpeting
Cost of painting = 216,120 - 106,800
Cost of painting = GHe 109,320
