Write each sum as fraction with a denominator of 100 and as a decimal

Answers

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. :)

Finding Circumference The radius is cm. v cm OZ The circumference in terms of ais Using 3.14 for A, the approximate circumference of the circle is cm. d=2cm​

Answers

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

Answer:

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

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?

Answers

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 cost

The 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

how do I do 6 and 6/7 plus 2 and 3/14

Answers

To convert a mixed number into a fraction, you multiply the whole number by the denominator and that to the numerator, then you carry over the denominator,
Let me clarify for 6 6/7, you multiply the 7 and 6 to get 42, then the 6 the is above the 7 is added onto 42 to give us 42, we carry our denominator of seven over and get [48/7,]

Then we do 2 3/14, multiply 2 by 14 and add 3, the carry over the denominator of 14, giving us [31/14]

Finally, we multiply 48/7 by 2/2 to give us 96/14 and add that to 31/14, this gives us 127/14 which can be converted into mixed numbers by finding the whole number of times that 14 goes into 127, which is 9, the remainder is 1 so you keep that on the numerator and you get 9 and 1/14
