I'm over thinking this please help it is multiple choice

The answer is .22222..., 3/10, .53, and 3/5.

Hope this helps!

Hello there!

The numbers in order from least to greatest are:

0.2222, 3/10, 0.53, 3/5

Start by turning all the numbers into either decimals. To do this, take the two fractions, 3/5 and 3/10 and divide them out.

3 divided by 5 = 0.6

3 divided by 10 = 0.3

Now let's look at our numbers again.

0.3, 0.222, 0.6, 0.53.

We know that 2 is less than 3, and 3 is less than 5, and 5 is less than 6, so lets rearrange the numbers into that order.

0.2222, 0.3, 0.53, 0.6

Now, convert any fractions that were converted into decimals back into their original forms.

0.2222, 3/10, 0.53, 3/5

This is your final answer. I hope this helps and have a great day!

Step-by-step explanation:

Got a 100 on it.

Final answer:

To cover a rectangular garden measuring 10 feet by 8 feet, multiply the length by the width to get an area of 80 square feet, which is the amount of material needed.

Explanation:

Calculating the Area of a Rectangular Garden

To determine the number of square feet required to cover your rectangular garden, you need to calculate the area of the garden. The area of a rectangle is found by multiplying the length by the width. In this case, the garden has a length of 10 feet and a width of 8 feet.

Steps to Calculate the Area

Measure the length and width of the garden using a measuring tape.

Multiply the length by the width to get the area in square feet: 10 feet (length) × 8 feet (width) = 80 square feet.

Therefore, you would need 80 square feet of material to cover the entire garden.

[tex](1-7x)(1+9x) =- 63 {x}^{2} + 2x + 1[/tex]

EXPLANATION

The given product is (1-7x)(1+9x).

Expand using the distributive property.

[tex](1-7x)(1+9x) = 1(1 + 9x) - 7x(1 + 9x)[/tex]

[tex](1-7x)(1+9x) = 1 + 9x - 7x - 63 {x}^{2}[/tex]

Simplify to obtain:

[tex](1-7x)(1+9x) = 1 + 2x - 63 {x}^{2}[/tex]

You can rewrite in standard form to get,

[tex](1-7x)(1+9x) =- 63 {x}^{2} + 2x + 1[/tex]

Answer:

1+2x-63x^2

Step-by-step explanation:

factor 1(1+9x)=1+9X

-7x(1+9x)=-7x-63x^2

add 1+9x-7x-63x2

37.5% as a fraction is 3/8.

Answer:

3/8

Step-by-step explanation:

To write a percent as a fraction, divide the percent by 100.

37.5% = 37.5/100

Now we reduce the fraction. First, multiply the numerator and denominator by 2 to get rid of the decimal in the numerator.

37.5% = 37.5/100 = 75/200

Both the numerator and denominator are divisible by 5, so we divide them by 5.

37.5% = 37.5/100 = 75/200 = 15/40

Both the numerator and denominator are divisible by 5 again, so we divide them by 5 again.

37.5% = 37.5/100 = 75/200 = 15/40 = 3/8

Answer: 37.5% = 3/8

The answer is:

The area of this figure is 946 square inches.

We can see that the figure is composed by two rectangles with diferrent dimensions, so, to calculate the area of the entire figure.

So,

For the first rectangle, we have:

The area will be:

[tex]Area=Base*Height=7in*28in=196in^{2}[/tex]

For the second rectangle, we have:

[tex]Base=25in\\Height=30in[/tex]

The area will be:

[tex]Area=Base*Height=30in*25in=750in^{2}[/tex]

Now, calculating the area of the entire figure, we have:

[tex]TotalArea=FirstRectangleArea+SecondRectangleArea\\\\TotalArea=196in^{2}+750in^{2}=946in^{2}[/tex]

Answer:

Step-by-step explanation:

The formula of a distance between two points:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We have the points (7, -4) and (7, 9). Substitute:

[tex]d=\sqrt{(7-7)^2+(9-(-4))^2}=\sqrt{0+13^2}=\sqrt{13^2}=13[/tex]

Used [tex]\sqrt{a^2}=a[/tex]

Answer:

a) yes they are similar

b)Proved below

c)Proved below

Step-by-step explanation:

a) rectangle 1 and 2 are similar by definition of similar rectangles.

Definition of similar rectangles states that two rectangles are similar if they have same shape but different sizes. The ratio between their corresponding sides are same, in this case as rectangle 2 is made by multiplying each dimension of Rectangle 1 by a

factor of k, where k>0 thus providing same proportion in length of different corresponding sides of two rectangles hence rectangle 1 and 2 are similar.

b) Perimeter of rectangle 1, P1= s1+ s2+ s3 + s4

As each side of rectangle 2 is formed by multiplying each dimension of Rectangle 1 by k, therefore

  Perimeter of rectangle 2, P2= k.s1+ k.s2+ k.s3 + k.s4

Taking k common

                                                  = k(s1+ s2+ s3 + s4)

Substituting P1 in above expression

                                               P2  =k(P1)

Hence the perimeter of Rectangle 2 is k times the perimeter of Rectangle 1.

c) Area of rectangle 1, A1= 2(s1)(s2)

As each side of rectangle 2 is formed by multiplying each dimension of Rectangle 1 by k, therefore

Area of rectangle 2, A2= 2(k.s1)(k.s2)

                                       = 2k^2(s1)(s2)

                                        = k^2 [2(s1)(s2)]

Substituting A1 in above expression

                                        A2 = k^2(A1)

Hence the area of Rectangle 2 is k2 times the area of Rectangle 1 !

Answer:

y = 0.10x + 8, $12

Step-by-step explanation:

y = monthly bill

x = number of message units

Each message unit costs $0.10, so the cost of x message units is 0.10x.  The phone adds $8 to the monthly bill.  Therefore:

y = 0.10x + 8

If x = 40, then:

y = 0.10 (40) + 8

y = 4 + 8

y = 12

The monthly bill is $12.

Step-by-step explanation:

Given that slope of the line is m = 1

And the line passes through the point (-3,5).

Now we need to graph the line using above information. So begin by graphing the point (-3,5).

Slope means rise/run

Then slope = 1 means rise/run=1=1/1

means move point 1 unit up then 1 unit right

then new point is at (-2,6).

Now draw a line joining both points to get the final graph.

Answer:

x = - 1

Step-by-step explanation:

Given

3x + 2 = y and y = - 1

Substitute y = - 1 into the equation and solve for x, that is

3x + 2 = - 1 ( subtract 2 from both sides )

3x = - 3 ( divide both sides by 3 )

x = - 1

This is verified by the point on the graph with coordinates (- 1, - 1)

Method 1: By substitution

Step 1: In the equation 3x + 2 = y when you see a y replace it with -1

3x + 2 = -1

Step 2: Combine like terms by subtracting 2 to both sides

3x + (2-2) = -1 - 2

3x = -3

Step 3: Isolate x by dividing 3 to both sides

[tex]\frac{3x}{3} = \frac{-3}{3}[/tex]

x = -1

Method 2: By looking at the graph

To solve this way you see where the line on the graph has y = -1 and look for its complimentary x

If you look at the graph attached below you can see that at y = -1 the x also equals -1

x = -1

[tex]( \frac{f}{g} )(x) = \frac{1}{3} ( {x}^{2} + 3x + 9)[/tex]

EXPLANATION

The given functions are

[tex]f(x) = {x}^{3} - 27[/tex]

and

[tex]g(x) = 3x - 9[/tex]

[tex]( \frac{f}{g} )(x) = \frac{f(x)}{g(x)} [/tex]

[tex]( \frac{f}{g} )(x) = \frac{ {x}^{3} - 27}{3x - 9} [/tex]

[tex]( \frac{f}{g} )(x) = \frac{ (x - 3)( {x}^{2} + 3x + 9) }{3(x -3 )} [/tex]

Cancel the common factors,

[tex]( \frac{f}{g} )(x) = \frac{ {x}^{2} + 3x + 9 }{3} [/tex]

OR

[tex]( \frac{f}{g} )(x) = \frac{1}{3} ( {x}^{2} + 3x + 9)[/tex]

The initial number of carbon-14 atoms in the organism at the time of death was 200 atoms.

The initial number of carbon-14 atoms in the organism at death can be calculated using the formula for exponential decay:

[tex]\[ N(t) = N_0 e^{-\lambda t} \][/tex]

where:

- [tex]\( N(t) \)[/tex] is the number of undecayed carbon-14 atoms at time [tex]\( t \),[/tex]

- [tex]\( N_0 \)[/tex] is the initial number of carbon-14 atoms at time \[tex]( t = 0 \[/tex]) (the time of death),

- [tex]\( \lambda \)[/tex] is the decay constant for carbon-14,

- [tex]\( t \)[/tex] is the time that has passed since the time of death.

 Given that after 5730 years (the half-life of carbon-14), the number of undecayed carbon-14 atoms is half the initial amount, we can write:

[tex]\[ \frac{N_0}{2} = N_0 e^{-\lambda \times 5730} \][/tex]

To find the decay constant [tex]\( \lambda \)[/tex], we use the half-life formula:

[tex]\[ \lambda = \frac{\ln(2)}{t_{1/2}} \][/tex]

 where [tex]\( t_{1/2} \)[/tex] is the half-life of carbon-14, which is 5730 years. Plugging in the values:

[tex]\[ \lambda = \frac{\ln(2)}{5730} \][/tex]

Now, we can solve for [tex]\( N_0 \)[/tex]using the information provided:

[tex]\[ 100 = N_0 e^{-\frac{\ln(2)}{5730} \times 573[/tex]

 Since [tex]\( e^{-\ln(2)} = \frac{1}{2} \)[/tex], the equation simplifies to:

[tex]\[ 100 = N_0 \times \frac{1}{2} \][/tex]

Solving for [tex]\( N_0 \):[/tex]

[tex]\[ N_0 = 100 \times 2 \][/tex]

[tex]\[ N_0 = 200 \][/tex]

 Therefore, the initial number of carbon-14 atoms in the organism at the time of death was 200 atoms.
