Step-by-step explanation:
the volume of a soap bubble is 2,308.4 mm ^3. Find the radius and diameter of the soap bubble. Use 3.14 for pi
Answer:
r = 8.2mm
d = 816.4mm
Step-by-step explanation:
Let the soap be spherical in nature
Volume of a sphere = 4/3 πr³
r is the radius
Given that V = 2308.4mm^3
Substitute
2308.4 = 4/3 πr³
2308 = 4/3 (3.14)r³
2308.4 * 3 = 12.56r³
6,925.2 = 12.56r³
r³ = 6,925.2 /12.56
r³ = 551.37
r = 8.2mm
diameter = 2r
diameter = 2(8.2)
diameter = 16.4mm

What is the measure of angle LMN ?
Answer:
g = 9°
hence LMN = 135 + 18 = 153°
Step-by-step explanation:
straight line is 180°
180 - 18 = 162
162 = 18g
g = 9
Answer:
Step-by-step explanation:
So try to find the total angle so
15g+18+3g=180
18g=180-18
18g=162
g=9
angle LMN=15x9+18
=135+18
LMN=153 degrees
angle PMN=3x9
= 27 degrees
An item is regularly priced at $60 . Lucy bought it on sale for 60% off the regular price. How much did Lucy pay?
Answer:
$24
60% of 60 is 36 so to subtract 60% from the total $60 you would do 60-36=24

The figure shows four smaller squares in the corners of a large square. the smaller squares have sides of length 1cm, 2cm, 3cm and 4cm in anticlockwise order and the sides of the large square have length of 11cm.
What is the area of the shaded quadrilateral? (see attachment)
Answer:
B. 36 [tex]cm^{2}[/tex]
Step-by-step explanation:
The shaded quadrilateral has a shape of a trapezium.
Area of a trapezium = [tex]\frac{1}{2}[/tex](a + b)h
where: a is the side length parallel to the base, b is the base and h is the height.
The height of the figure = 11 - (4 + 1)
= 11 - 5
= 6
The height of the figure is 6 cm.
The length of its base = 11 - (1 + 2)
= 11 - 3
= 8
The length of its base is 8 cm.
The length of the side parallel to base = 11 - (4 + 3)
= 11 - 7
= 4
The parallel side length to base is 4 cm.
Area of quadrilateral = [tex]\frac{1}{2}[/tex](a + b)h
= [tex]\frac{1}{2}[/tex](4 + 8)6
= 12 x 3
= 36
Area of quadrilateral = 36 [tex]cm^{2}[/tex]
Function f approximately represents the trajectory of an airplane in an air show, where x is the horizontal distance of the flight, in kilometers. What is the symmetry of the function?
Answer:
[tex](\frac{3}{2},102)[/tex]
Step-by-step explanation:
Given
[tex]f(x)=88x^2-264x+300[/tex] --- Missing from the question
Required
The symmetry
First, we express f(x) as: [tex]f(x) = a(x - h)^2 + k[/tex]
Where the symmetry is: (h, y) and x = h
Equate f(x) to 0
[tex]88x^2-264x+300 = 0[/tex]
Subtract 300 from both sides
[tex]88x^2-264x+300 - 300= 0 - 300[/tex]
[tex]88x^2 - 264x= - 300[/tex]
Factorize
[tex]88(x^2 - 3x) = -300[/tex]
On the left-hand side, the coefficient of x is -3.
Divide by 2 and add the square to both sides.
So, we have:
[tex]88(x^2 - 3x) + (\frac{3}{2})^2 = -300 + (\frac{3}{2})^2[/tex]
Multiply the new terms by 88 (to make it factorizable)
[tex]88(x^2 - 3x ) +88* (\frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
Factorize
[tex]88(x^2 - 3x + (\frac{3}{2})^2) = -300 + 88 * (\frac{3}{2})^2[/tex]
The quadratic expression in the bracket is a perfect square. This gives:
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * \frac{9}{4}[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 22 * 9[/tex]
[tex]88(x - \frac{3}{2})^2 = -102[/tex]
Add 102 to both sides
[tex]88(x - \frac{3}{2})^2 +102= -102 + 102[/tex]
[tex]88(x - \frac{3}{2})^2 +102= 0[/tex]
Equate to y
[tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
Recall that:
The symmetry is: (h, y)
By comparison with [tex]f(x) = a(x - h)^2 + k[/tex] and x = h
[tex]h = \frac{3}{2}[/tex]
So: [tex]x = \frac{3}{2}[/tex]
Substitute [tex]x = \frac{3}{2}[/tex] in [tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(\frac{3}{2} - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(0)^2 +102[/tex]
[tex]y = 0 +102[/tex]
[tex]y = 102[/tex]
So, the symmetry is: [tex](\frac{3}{2},102)[/tex]

Valerie is sliding down a waterslide at a vertical rate of -5 m/s after 1 second she is 25 m from the bottom of the slide. Write this situation in point slope form: m(x-x1)=(y-y1)
Answer:
15
Step-by-step explanation:
becasue the slope is very harddddd
Can someone please help me with math
Answer:
B
Step-by-step explanation:
they want us to find the equation in slope intercept form
which is y= mx + b
where m = slope and b = y intercept
the slope is change in y over change in x
as y goes up 1 x goes up 1 so the slope is 1 or m=1
the y intercept is at point (0,1)
so the y intercept is 1
now we add it all together and get that the equation Is
y=x+1
help its for a friend
1) Which of the following is true about circles
2 radius's for a circle is equal to it's diameter
1 diameter of a circle is equal to it's circumference
pi is a ratio of the distance around a circle to the distance across a circle
Circumference is distance across a circle
Circumference for a circle is found by multiplying pi by diameter
Circumference and Area of a circle are the same thing
