find area of 1 small bubble
πr² = π × 5²
= 78.54
total area of 4 small bubble
78.54 × 4 = 314.16
total area of 4 small bubble = area of big bubble
= 314.16
find it's radius
πr² = 314.16
r² = 314.16 ÷ π
r² = 100
r = √100
r = 10
Answer:
AREA OF LARGE BUBBLE=PI×R^2
AREA OF 1 SMALL BUBBLE =PI×r^2
then area of 4 small bubble =(PI×r^2)×4
now,
area of large bubble =area of 4 small bubble
PI×R^2=4×(PI×r^2)
R= 10 cm

A rectangular piece of metal 12 cm long 18 cm wide and 10 cm high is melted and recast into 45 cylindrical plates,each of radius 1.2 cm.Find the thickness of each plate giving your answer correct to 2 decimal places?
Answer:
10.61 cm
Step-by-step explanation:
From the question,
The volume of the rectangular piece of metal = Volume of the 45 cylindrical plates.
Volume of a cuboid = 45×volume of a cylinder
lwh = 45×πr²h..................... Equation 1
Where l = length of the rectangular piece of metal, w = width of the rectangular piece of metal, h = height of the rectangular piece of metal, r = radius of the cylindrical plates, h = thickness of the cylindrical plates.
make h the subject of the equation
h = lwh/(45πr²).................... Equation 2
Given: l = 12 cm, w = 18 cm, h = 10 cm. r = 1.2 cm
Constant: π = 3.142.
Substitute these values into equation 2
h = (12×18×10)/(45×3.142×1.2²)
h = 2160/203.60
h = 10.61 cm.
How do you graph a quadratic function?
Answer:
Step-by-step explanation:
Compare the equation with the standard form, y=ax2+bx+c . Since the value of a is positive, the parabola opens up.
So, y=0 implies, by the zero product property, x+4=0 or x−2=0 .
Substitute x=−1 in the equation y=−x2−2x+8 to find the y -coordinate of the vertex.

Answer:
Step-by-step explanation:
Sin(x) = opposite / hypotenuse.
opposite = 28 The opposite is not connected to the angle.
hypotenuse= 35
Sin(x) = 28/35 = 4/5
Cos(x) = adjacent / hypotenuse.
The adjacent side is part of the angle
adjacent = 21
hypotenuse = 35
Cos(x) = 21 / 35 = 3/5
Tan(x) = opposite / adjacent
opposite = 28
adjacent = 21
Tan(x) = 28/21
Tan(x) = 4/3

45 inch board cut into three pieces so that the second piece is 3 times as long as the first piece and the third piece is 5 times as long as the first piece . find the lengths of all three pieces
Answer:65
Step-by-step explanation:
Length of first, second and third piece are 5, 15 ,25 inch
Given that;
Length of board = 45 inch
Second cut is 3 times as long as the first piece
Third cut is 5 times as long as the first piece
Find:
Length of all three piece
Computation:
Assume;
Length of first piece = a
So,
Length of second piece = 3a
Length of third piece = 5a
So,
Length of first piece + Length of second piece + Length of third piece = Total length
a + 3a + 5a = 45
9a = 45
a = 5
So,
Length of first piece = a
Length of first piece = 5 inch
Length of second piece = 3a = 3(5)
Length of second piece = 15 inch
Length of third piece = 5a = 5(5)
Length of third piece = 25 inch

Answer: it would be the "=" sign
Step-by-step explanation: this is because 2/3 and 6/9 are equivalent fractions. you want to find the greatest common factor between 6 and 9 which is 3. you multiply that by the numerator and denominator. therefore, the symbol that compares these mixed numbers is "=".
what is the value of the fourth term in a geometric sequence for which a1=30 and r=1/2
Answer:
a(4) = 15/4
Step-by-step explanation:
The general formula for a geometric series with common ratio r and first term a(1) is
a(n) = a(1)*r^(n - 1)
and so, if a(1) = 30 and r = 1/2, we have
a(n) = 30*(1/2)^(n - 1)
and the fourth term is then:
a(4) = 30*(1/2)^(4 - 1) = 30/8 = 15/4

<u is 75
< v is 29
<w is 76
Step-by-step explanation:
< u + < v +< w = 180
<w + 3x+35 = 180
so 3x+35= <v+ <u
3x+35=x+52+x+6
3x+35= 2x+58
x+35=58
x= 23
so each angle
U= (23+52)= 75
V= (23+6)= 29
W=180-75-29= 76
or 3(23)+35+w=180
104+w=180
w= 76

Answer:
9 1/9 is the answer
Step-by-step explanation:

[tex]\frac{1}{9} + 9[/tex]
whole numbers always go over a 1
[tex]\frac{1}{9} + \frac{9}{1}[/tex]
make 9/1 have the same denominator as 1/9 by multiplying the top and bottom with 9
[tex]\frac{1}{9} + \frac{81}{9}[/tex] [tex]= \frac{82}{9}[/tex]
the simplify 82/9

Trevor pet goat weighed 6 3/ pounds when oit was born. By age 3 the goat weighted 8 times as much. Fill in each box with a number or sysmobe to answer tthis question.
Answer: 51 pounds
Step-by-step explanation:
Since the goat weighed 6 3/8 pounds and weighed 8 times as much by age 3, the weight of the goat at age 3 will be gotten by multiplying 6 3/8 by 8. This will be:
= 6 3/8 × 8
We change 6 3/8 to an improper Fraction
= 51/8 × 8
= 51 pounds
The weight is 51 pounds
Four rays meet at a common endpoint. Find the value of x. Find the measurement of angle CAD, if angle BAC =60, DAE= 90 and angle BAE= 12x, CAD=3x
Answer:
x = 14
<CAD = 42degrees
Step-by-step explanation:
Since all the rays meet at a point, the sum of all the angles at the point will be 360 degrees, since angle at a point is 360degrees
Taking the sum of all the angles and equating to 360, we will have;
<BAC + <DAE + <BAE + <CAD = 360
60+90+12x+3x = 360
150 + 15x = 360
15x = 360 - 150
15x = 210
x = 210//15
x = 14
Get <CAD
Since <CAD = 3x
<CAD = 3(14)
<CAD = 42 degrees
Hence the measure of angle CAD is 42degrees

Answer:
2400 [tex]$cm^3$[/tex]
Step-by-step explanation:
From the triangle on the left, we can see that height is 15cm and from the triangle on the right, we can see that base is 8cm of the triangle, as both triangles are identical. So the area of the triangle is,
[tex]b = 8 cm\\h = 15cm[/tex]
[tex]A = \frac{1}{2}bh\\= \frac{1}{2}\times8\times15 cm^2\\= 60 cm^2[/tex]
The area of the prism should be the length of the prism times the area of the triangle. So it is [tex]60 cm^2 \times 40 cm = 2400 cm^3[/tex]
