What is the scale factor and how do you find it?

1. There would be 2 slices as the denominator is 2.

2. There would be 5 slices as the denominator is 5.

3. As each slice gets smaller, the denominator gets bigger, because the bigger the denominator is, the more pieces it needs to make a whole.

Hope this helps :)

There are 2 pieces if each slice is 1/2 of a loaf, and 5 pieces if each slice is 1/5 of a loaf, and the total number of pieces get increases if each slice gets smaller.

When fractions are represented on a number line, we can plot them on a number line just like we can with whole numbers and integers. Parts of a whole are represented by fractions. In order to depict fractions on a number line, equal pieces of a whole are divided.

Given A loaf of bread is cut into slices.

1. If each slice is 1/2 of a loaf, how many slices are there,

here slices are  1/2 of the loaf so the loaf is divided into two equal parts,

1/2 + 1/2 = 1

2. If each slice is 1/5 of a loaf, how many slices are there,

here loaf has 5 equal parts,

1/5 + 1/5 + 1/5 +1/5 + 1/5 = 1 loaf

3. What happens to the number of slices as each slice gets smaller?

the value of the denominator in fraction goes on increasing and since the value is increasing the number of slices also gets increases.

Hence there are 2 pieces for 1/2 of the loaf,

5 pieces for 1/5 of the loaf,

and the number of slices increases when each slice gets smaller.

Answer:

$1456.25

Step-by-step explanation:

Given data

P= $1,250

t= 3 years

r=5.5%

The compound interest expression is given as

A= P(1+r)^t

substitute

A=  1250(1+0.055*3)

A=  1250(1+ 0.165)

A= 1250(1.165)

A= 1456.25

Hence the amount after 3 years is $1456.25

Answer:

30

Step-by-step explanation:

Answer:

4/35, 0.114, 11.4%

Step-by-step explanation:

Answer:

y = -x + 30

Step-by-step explanation:

You will want to put the equation in the form y = mx + b where m is the slope and b is the y-intercept (an example is y = 2x - 1).

First, to find the slope you want to find how much x goes up by when y goes up by 1. You know from the table that when y goes up by 5, x goes up by -5 (using the points (10, 20) and (5, 25))

Then, you can divide each value by 5, so it would be when y goes up by 1, x goes up by -1. That means the slope is -1.

So far, the equation is y = -x + b. To find b, you can plug in one of the points you have and solve for b. For example, substitute in x = 10 and y = 20, so:

20 = -10 + b

add 10 to both sides

30 = b

So you know the equation is y = -x + 30

Please let me know if any parts of these explanation are confusing, I definitely think this concept can be confusing at time. Good luck with your work! :)

Answer:

To create an equation, you need to find the slope first. The slope formula is [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]. Let's use two random coordinates: (10,20) and (5,25). Plug in these digits into the formula to get [tex]\frac{25-20}{5-10}[/tex]. Simplify to get [tex]\frac{5}{-5}[/tex] or -1. The equation would look like y=-x+b. Now we need to find b. Again, let's use a random coordinate: (10,20). Plug in the digits into the variables to get 20=-10+b. Add 10 on both sides to get 30=b. So, the equation would be y=-x+30.

Answer:

5544cm (squared)

Step-by-step explanation:

Surface area of a sphere=4πr  (squared) =4×  7/ 22 ×21×21cm  (squared)  

Surface area of the sphere=5544cm  

.

Answer:

Area = 5164.8 cm; volume = 38792.4 centimeters

Step-by-step explanation:

Since the radius is known, we can substitute it for r in the first formula.

A = 4πr²

A = 4π(21)²

A = 4π(411)

A = 12.566370614359 * 411

A = 5164.8

V = 4/3πr^3

V = 4/3π21^3

V = 4/3π(9261)

V = 4.1887902047863 * 9261

V - 38792.4

Step-by-step explanation:

Answer: The surface area is 452.39in²

Step-by-step explanation:

Formula

A=4πr²

d= 2 r

Solving for A

A=πd²=π·12²≈452.38934in²

The surface area of a sphere that has a diameter of 12 inches is 452.39 in².

To solve the question, we need to know what the surface area of a sphere is.

The surface area of a sphere is given by A = 4πr² where

Given that d = 12 inches, r = d/2 = 12 in/2 = 6 in

Substituting the value of r into A, we have

A = 4πr²

A = 4π × (6 in)²

A = 4π × 36 in²

A = 144π in²

A = 452.39 in²

So, the surface area of a sphere that has a diameter of 12 inches is 452.39 in².

Zeroes: x = 4, x = -6

The vertex is at ( -1 , 50 )

Step-by-step explanation:

I'll do the first one, you try the rest

All of these are written in y = a(x - x1)(x - x2) where x1 and x2 are given and x are the two different zeroes (or x-intercepts)

f(x) = -2(x-4)(x+6)

The zeroes are x - 4 = 0 and x + 6 = 0 if you solve, you get 4 and -6

Zeroes: x = 4, x = -6

The x value of the vertex can be found using -b/2a (in the form ax^2 + bx + c)

First expand f(x)

-2(x^2 + 2x - 24) => -2x^2 - 4x + 48

b = -4 and a = -2

-(-4)/2(-2) = 4/-4 = -1

the x-value of the vertex is -1

Now substitute -1 as x to find the y-value of the vertex

-2(-1-4)(-1+6) = -2(-5)(5) = 50 <= y-value of vertex

The vertex is at ( -1 , 50 )

Answer:

Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. Standard notation is the normal way of writing numbers.

Answer:

Scientific notation: c * 10^n where 1 <= c < 10

Now standard notation is basically multiplying c * 10^n out

For example:

Scientific notation: 4.5 * 10^4

Would be written as 45000 in standard notation (either multiply by 4.5 * 10^4 or just simply move the decimal in 4.5 four places to the right)

For example:

Scientific notation: 0.6 * 10^-3

Would be written as 0.0006 in standard notation (either multiply by 4.5 * 10^-3 or just simply move the decimal in 0.6 three places to the left)

Answer:

7.4% increase (approximated)

Step-by-step explanation:

✔️Dimension of the original rectangle:

Length = 30 cm

Width = 20 cm

Perimeter = 2(L + W) = 2(20 + 30) = 2(50) = 100 cm

✔️Dimension of new rectangle:

Length is increased by 10% = 10/100 × 30cm = 3 cm

New length = 30 + 3 = 33 cm

Width is increased by 5% = 5/100 × 20cm = 1 cm

New width = 20 + 1 = 21 cm

✔️Perimeter of New rectangle = 2(L + W) = 2(33 + 21) = 2(54) = 108 cm

✔️Percentage increase in the perimeter of the rectangle = (perimeter of New rectangle - perimeter of original rectangle)/perimeter of original rectangle × 100

= (108 - 100)/108 × 100

= 8/108 × 100

≈ 7.4% increase

Please find attached the required triangle drawn with Microsoft Visio

Step-by-step explanation:

The isosceles triangle ΔPQR we are to construct has the following parameters;

∠PQR = 90°

Length of side hypotenuse PR = 4 cm

Therefore, given that the triangle is right triangle is an isosceles triangle the length of each of the side legs are equal

Therefore, we have;

Length of PQ = Length of QR

The length of the legs , [tex]\overline {PQ}[/tex] and [tex]\overline {QR}[/tex], are given by Pythagoras's theorem as follows;

[tex]\overline {PR}[/tex] = √([tex]\overline {PQ}[/tex]² + [tex]\overline {QR}[/tex]²) = √([tex]\overline {PQ}[/tex]² + [tex]\overline {PQ}[/tex]²) = [tex]\overline {PQ}[/tex]·√2

∴ [tex]\overline {PQ}[/tex] = 4 cm/(√2) = 2·√2 cm = [tex]\overline {QR}[/tex]
