Answer:7picm Circumference = pi x d Diameter = 7 C = pi x 7 C = 7pi cm.
Step-by-step explanation:
The circumference of the circle with diameter 2 cm is 6.28 cm.
What is a circle?A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.
Given that a circle has a diameter of 2 cm we need to find its circumference,
The circumference of a circle is given by, π × diameter
Therefore, the circumference of the circle with diameter 2 cm =
= π × diameter
= π × 2
= 3.14 × 2
= 6.28 cm
Hence, the circumference of the circle with diameter 2 cm is 6.28 cm

Choose a different point that lies directly on the graph of the line...
Answer:
Step-by-step explanation:
You got it right: the point (0, -1) is another point on the graph of y = 3x - 1.
Substituting 0 and -1 back into the equation, y = 3x - 1:
-1 = 3(0) - 1
So the pint is also a solution to the equation.

Answer: x < -3.5
Step-by-step explanation:
Subtract 3 from both sides and we get

What is the exact volume of the cone
Answer:
V = [tex]\frac{400}{3}[/tex][tex]\pi[/tex]

Volume of a cone is:
[tex]V = \pi r^{2} \frac{h}{3}[/tex]
Substitute values given:
[tex]V = \pi (5^{2} )(\frac{16}{3})[/tex]
[tex]V = \pi (25)(\frac{16}{3} )[/tex]
V = [tex]\pi \frac{400}{3}[/tex]
V = [tex]\frac{400}{3}[/tex][tex]\pi[/tex]

Write each sum as fraction with a denominator of 100 and as a decimal
Answer:
56/100 or 0.56
Step-by-step explanation:
you first need the dinominators to be the same so to figure that at you can do 100 divided by 10 which is 10. so to make the doniomators even you need to multipy the 2/10 by 10. so 2x10=20 and 10x10=100 so that makes the fraction 20/100. now you have 20/100 + 36/100 =? which makes it a lot easier. so now all you do is add ONLY THE NUMERATOR so you do 20+36 which is 56 and you keep the 100 and that 56/100.
To make it into a decimal, this one is easy because the denominater is 100 so you just take 56.0 and move the decimal two place values so its 0.56. :)

[tex]\sf x = 92[/tex]An open box with a square base is constructed so that it has a volume of 64in^3. The base needs to be made out of a material that costs twice as much as the sides. What are the dimensions of the box, what are the dimensions of the box x and y (x being the width and depth of the square dimensions, and y being the height of the box) which will minimize the cost of the box?
The volume of a box is the amount of space in the box
The dimensions that minimize the cost of the box is 4 in by 4 in by 4 in
How to determine the dimensions that minimize the costThe dimensions of the box are:
Width = x
Depth = y
So, the volume (V) is:
[tex]V = x^2y[/tex]
The volume is given as 64 cubic inches.
So, we have:
[tex]x^2y = 64[/tex]
Make y the subject
[tex]y = \frac{64}{x^2}[/tex]
The surface area of the box is calculated as:
[tex]A =x^2 + 4xy[/tex]
The cost is:
[tex]C = 2x^2 + 4xy[/tex] --- the base is twice as expensive as the sides
Substitute [tex]y = \frac{64}{x^2}[/tex]
[tex]C = 2x^2 + 4x * \frac{64}{x^2}[/tex]
[tex]C =2x^2 + \frac{256}{x}[/tex]
Differentiate
[tex]C' =4x - \frac{256}{x^2}[/tex]
Set to 0
[tex]4x - \frac{256}{x^2} = 0[/tex]
Multiply through by x^2
[tex]4x^3 - 256= 0[/tex]
Divide through by 4
[tex]x^3 - 64= 0[/tex]
Add 64 to both sides
[tex]x^3 = 64[/tex]
Take the cube roots of both sides
[tex]x = 4[/tex]
Recall that:
[tex]y = \frac{64}{x^2}[/tex]
So, we have:
[tex]y = \frac{64}{4^2}[/tex]
[tex]y = 4[/tex]
Hence, the dimensions that minimize the cost of the box is 4 in by 4 in by 4 in

Which measurements of two similar triangles are the same?
Step-by-step explanation:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion. In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

Answer:
4/7
Step-by-step explanation:
The conditional probability of A and B happening : P(AnB) is 1/6, and the conditional probability of B happening : P(B) is 7/24, the probability of A happening is 1/6 : 7/24 = 4/7
P(A/B) = Given that B occurs, find the probability of A occuring
