Answer:
70 centimeters.
1 meter = 100 centimeters
--> 100-30=70 centimeters.
Answer:
There are 100 cm in 1 m.
So with that, if you put 4.5 m in cm you get 450 cm of ribbon.
Then divide 450 by 4.5 to see how many times you can take out 4.5 cm from the amount you have.
450/4.5 = 100
So you can get 100 pices of ribbon each 4.5 cm
from 4.5 m of ribbon

A town has a fireworks display, where fireworks are set off from a bridge over a lake. The function h (t) = -16t2 + 150t + 10.5 represents
the approximate height of each firework, in feet, t seconds after it is launched.
Approximately when do the fireworks reach their maximum height?
Answer:
h(t) = 4.68 seconds
Step-by-step explanation:
The function that represents the height of each firework in feet is :
[tex]h (t) = -16t^2 + 150t + 10.5[/tex] .....(1)
We need to find the time the fireworks take to reach their maximum height. For maximum height,
dh/dt = 0
So,
[tex]\dfrac{d}{dt}(-16t^2 + 150t + 10.5 )=0\\\\-32t+150=0\\\\t=\dfrac{150}{32}\\\\t=4.68\ s[/tex]
Put t = 4.68 in equation (1).
[tex]h (t) = -16(4.68)^2 + 150(4.68)+ 10.5\\\\h(t)=362.06\ text{feet}[/tex]
So, the fireworks will take 4.68 seconds to their maximum height.

The side lengths of the following right triangle 15,20 and 25, as shown below. The altitude from the right angle splits the hypotenuse into line segments of length x and y. Solve for h,x, and y.
Answer:
[tex]h = 12[/tex]
[tex]x = 9[/tex]
[tex]y= 16[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find h, x and y
Let the base of the triangle be 15.
So, the area is:
[tex]A = \frac{1}{2} * 15 * 20[/tex]
[tex]i.e\ height = 20[/tex]
[tex]A = \frac{1}{2} * 300[/tex]
[tex]A = 150[/tex]
Let the base of the triangle be 25.
So, the area is:
[tex]A = \frac{1}{2} * 25 * h[/tex]
[tex]i.e\ height = h[/tex]
[tex]A = \frac{1}{2} * 25h[/tex]
Substitute [tex]A = 150[/tex]
[tex]\frac{1}{2}*25h = 150[/tex]
Solve for h
[tex]h = \frac{150 *2}{25}[/tex]
[tex]h = 6 *2[/tex]
[tex]h = 12[/tex]
Considering the smallest triangle
[tex]Hypotenuse = 15[/tex]
So:
[tex]15^2 = h^2 + x^2[/tex]
[tex]15^2 = 12^2 + x^2[/tex]
This gives:
[tex]15^2 - 12^2 = x^2[/tex]
[tex]81 = x^2[/tex]
Take square roots
[tex]9 =x[/tex]
[tex]x = 9[/tex]
Solving for y
[tex]x + y = 25[/tex]
[tex]y= 25 - x[/tex]
[tex]y= 25 - 9[/tex]
[tex]y= 16[/tex]

Step-by-step explanation:
If a triangle is right, then it has a
hypotenuse.
Choose the equivalent statement.
A. If a triangle does not have a hypotenuse, then it is not a right
triangle.
B. If a triangle is not a right triangle, then it has a hypotenuse.
C. If a triangle does not have a hypotenuse, then it is a right
triangle.
The equivalent statement would be choice A :)
Answer: A. If a triangle does not have a hypotenuse, then it is not a right
triangle.

Please Help! After one side of a square flower bed was enlarged by 2 ft and the other side was enlarged by 3 ft, the area of a new flower bed became twice the area of an old one. How long was the side of the old flower bed?
The problem says we have a square flower bed to start out with.
Let's have the sides of the squares be "x". The area of this original flower bed is [tex]x^{2}[/tex].
Then, one side of the square is enlarged by 2ft, and another side 3ft. Our new flower bed dimensions are now (x+2) and (x+3). Multiply (x+2) and (x+3) to find the area, which gets you [tex]5x^{2} +6x+6[/tex].
We also know that the new area of the flower bed is twice the size of the original flower bed. Multiply the original area by 2, you get [tex]2x^{2}[/tex].
With the new area and the doubled original area, we can now make an equation: [tex]5x^{2} +6x+6=2x^{2}[/tex]
Solve for x, you get 6.
Hope this explanation helped, maybe a bit too many details but there's your answer, 6!
The side length of the original bed is 6 units
Area of squareThe formula for finding the area of the square is expressed as:
A = x^2
If one side of a square flower bed was enlarged by 2 ft and the other side was enlarged by 3 ft, the area of the bed becomes;
A = (x+2)(x+3)
A = x^2 + 5x + 6
If the area of a new flower bed became twice the area of an old one, then;
5x^2 + 6x + 6 = 2x^2
On factorizing, the value of x is 6 which shows that the side length of the original bed is 6 units

Answer:
I think its 97.51
Step-by-step explanation:
Area of circle is A = [tex]\pi r^{2} = \pi 6^{2}[/tex]
Area of a triangle is [tex]\frac{\sqrt{3} }{4}a^{2}[/tex] = [tex]\frac{\sqrt{3} }{4}6^{2}[/tex]
Area of triangle = 15.59
Area of circle = 113.1
113.1 - 15.59 = 97.51
