Answer:
Width = 125 m
Length = 375 m.
Step-by-step explanation:
If the width = w then length l = 3w.
Perimeter = 2(w + l)
= 2(w + 3w)
2(w + 3w) = 1000
2 * 4w = 1000
w = 1000/8 = 125m
l = 3*125 = 375.
Step-by-step explanation:
width = x
length= 3x
perimeter of triangle =2( l + b)
1000 = 2( 3x + x )
1000÷ 2 = 4x
500=4x
x= 500÷ 4 = 125
width = 125
length = 125×3= 375
recheck by filling value
width= x = 125
length = 3x =375
perimeter = 2( l+ b)
= 2(375 + 125)
= 2× 500 = 1000
hence proved

Step-by-step explanation:
a helicopter flies over a city the helicopter changes it's altitude by -42.9m. then it changes it's altitude by another -15.4m what is the total change in the helicopters altitude
Answer:
The total change in the helicopter's altitude is [tex]-58.3[/tex].
Step-by-step explanation:
Create an equation.
[tex]-42.9 +(-15.4)[/tex]
Adding two negative numbers is always negative, so simply add the absolute values and make the answer a negative.
[tex]42.9+15.4 = 58.3[/tex]
Now, change the answer to a negative.
[tex]-58.3[/tex]
Thus, [tex]-58.3[/tex] is the answer.

To find:
The degree measure of each angle in the triangle.
Solution:According to the given information,

[tex]m\angleB=(5x+7)^\circm∠B=(5x+7) [/tex]
[tex]m\angleC=(4x+29)^\circm∠C=(4x+29) ∘[/tex]
Now,
[tex]m\angleA+m\angleB+m\angleC=180^\circm∠A+m∠B+m∠C=180 ∘[/tex]
(Angle sum property)
[tex]90^\circ+(5x+7)^\circ+(4x+29)^\circ=180^\circ90∘+(5x+7)∘+(4x+29) ∘ =180[/tex]∘
[tex](9x+126)^\circ=180^\circ(9x+126)∘ =180∘[/tex]
9x+126=1809x+126=180
9x=180-1269x=180−126
9x=549x=54
Divide both sides by 9.
[tex] \sf{x=\dfrac{54}{9}x=954}[/tex]

Now,

[tex]m\angle C=53^\circum \: ∠C=53[/tex]
Therefore,
The measures of ∠A, ∠B, ∠C are 90°, 37°, 53° respectively.

Find the slope between (9 , 75) and (13 , 95)
Explain why it does not matter which point you choose when writing the
equation of the line in point-slope form, given two points.
Answer:
because, it will completely change the slope
Step-by-step explanation:
It does not matter which point you choose when writing the
equation of the line in point-slope form because the slope of the line remains same.
What is a slope ?A slope can be thought of as rate of change of y axis with respect to x axis.
We have been asked in this statement that why it doesn't matter that which point we choose when writing the equation in point slope form.
Let us understand this with an example,Suppose we have two pair of points. (x₁,y₁) = (2,3) and (x₂,y₂) = (5,9).
We know slope(m) is = (y₂-y₁)/(x₂-x₁).
Slope(m₁) = (9-3)/(5-2)
= 6/3
= 2.
Now if interchange the points (x₁,y₁) = (5,9) and (x₂,y₂) = (2,3).
Slope(m₂) = (3-9)/(2-5)
= -6/-3
= 2.
So, even when interchanging the points the slope m₁ = m₂ this is the reason why it doesn't matter which point we choose.
