Andrea is painting a ceramic plate with a diameter of 12 inches. She wants to paint a thin blue line around the edge of the plate. How long will the line be?
Answer:
37.7 inches
Step-by-step explanation:
She wants to paint the line along the circumference of the plate.
The plate is circular; the circumference of a circle is given as:
C = πD
where D = diameter
The diameter of the plate is 12 inches, therefore:
C = π * 12 = 37.7 inches
The line will be 37.7 inches long.

Answer:
94.2 cm³
Step-by-step explanation:
The volume of a cone is
1/3 x h x π x r²
Plug in the values!
1/3 x 10 x 3.14 x 3²
1/3 x 10 x 3.14 x 9
3 x 10 x 3.14
30 x 3.14
94.2 cm³
Answer:
V =94.2 cm^3
Step-by-step explanation:
The volume of a cone is
V = 1/3 pi r^2 h
The radius is 3 and the height is 10
V = 1/3 ( 3.14) 3^2 * 10
V = 1/3 (3.14) *9(10)
V =94.2 cm^3
A cube has a volume of 1/512 cubic meter. Complete the explanation for finding the length of each side of the cube. Express your answers as simplified fractions when necessary
Answer:
1/8 meters
Step-by-step explanation:
The volume of a cube is given as the cube of the length of its sides. That is:
[tex]V = L^3[/tex]
where L = length of its side
The volume of the cube is 1/512 cubic metres.
This implies that:
[tex]\frac{1}{512} = L^3[/tex]
Find the cube root of both sides:
[tex]\sqrt[3]{\frac{1}{512} } = L\\\\=> L = \frac{1}{8}[/tex] meters
The cube has sides of length 1/8 meters
Select the correct answer. What are the solutions to this quadratic equation?
A)x=4+sqrt 10
B)x=-2+4 sqrt 10
C)x=4+2 sqrt 10
D)x=-4+4 sqrt 10
Answer:
Let's solve your equation
[tex]x^2+13=8x+37[/tex]
Step 1: Subtract 8x+37 from both sides.
[tex]x^2+13-(8x+37)=8x+37-(8x+37)[/tex]
[tex]x^2-8x-24=0[/tex]
For this equation: a= 1, b= -8, c= -24
Step 2: Use quadratic formula with a=1, b=-8, c=-24.
[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex]
[tex]x=\frac{-(-8)+\sqrt{(-8)^2-4(1)(-24)} }{2(1)}[/tex]
[tex]x=\frac{8+\sqrt{160} }{2}[/tex]
[tex]x=4+2\sqrt{10}[/tex] or [tex]x=4-2\sqrt{10}[/tex] This is the answer
So,the correct option is C

Jennifer is flying her kite and I get stuck in a tree. She knows the string on her coat is 17 feet long and she is 7 feet from the tree. How high up in the tree is the kite (in feet)?
Answer:
15.5 feet
Step-by-step explanation:
Find attached to this answer the appropriate diagram.
We would be using the Pythagoras Theorem to solve this question
The formula is given as:
a² + b² = c²
Where a = opposite side
b = adjacent side
c = hypotenuse
From the question,
a = opposite side = unknown
b = adjacent side = 7 feet
c = hypotenuse = 17 feet
We are to find the opposite side
Using the formula
a² + b² = c²
a² = c² - b²
a² = 17 feet² - 7 feet ²
a² = 289 feet² - 49 feet²
a² = 240 feet²
a = √240 feet²
a = 15.491933385 feet
Approximately 15.5 feet
Therefore, the kite is 15.5 feet high up in the tree.
16-2t=5t+9, find the value of t.
Answer:
[tex]t = 1[/tex]
Step-by-step explanation:
[tex]16 - 2t = 5t + 9 \\ 16 - 9 = 2t + 5t \\ 7 = 7t \\ \frac{7}{7} = \frac{7t}{7} \\ t = 1[/tex]
hope this helps
brainliest appreciated
good luck! have a nice day!
Answer:
[tex]t=1[/tex]
Step-by-step explanation:
[tex]16-2t=5t+9[/tex]
[tex](+16)+(-2t)=(+5t)+(9)[/tex]
Add [tex]-16[/tex] and [tex]-5t[/tex] on both sides.
[tex](-2t)+(-5t)=(+9)+(-16)[/tex]
Add the like terms and evaluate.
[tex]-2t-5t=9-16[/tex]

An object in the shape of a rectangular prism has a length of 5 inches, a width of 3 inches, and a height of 2 inches. The object's density is 8.3 grams per cubic centimeter. Find the mass of the object to the nearest gram.
Answer:
[tex]4,080grams[/tex]
Step-by-step explanation:
the formula for density is:
[tex]d=\frac{m}{V}[/tex]
where d is density, m is mass, and V is volume.
solving for m in the last equation:
[tex]m=d*V[/tex]
so if we find the volume and multiply it by the density [tex]d=8.3gr/cm^3[/tex] we will get the mass of the object.
The volume of a rectangular prism is given by:
[tex]V=l*w*h[/tex]
where [tex]l[/tex] is length, [tex]w[/tex] is width and [tex]h[/tex] is height:
[tex]l=5in\\w=3in\\h=2in[/tex]
we substitute to find the volume:
[tex]V=5in*3in*2in\\V=30in^3[/tex]
since the density has units of [tex]cm^3[/tex] we need the volume also in units of [tex]cm^3[/tex] , so we make the conversion using:
[tex]1in^3=16.3871cm^3[/tex]
multiplying by 30:
[tex]30in^3=491.612cm^3[/tex]
and now we find the mass with the equation:
[tex]m=d*V[/tex]
substituting d and V:
[tex]m=(8.3gr/cm^3)(491.612cm^2)\\m=4,080.36gr[/tex]
the nearest gram is: [tex]4,080grams[/tex]
