Answer:

A = 1100cm^2

Step by step Explanation:

given the dimensions of width and length of the picture are x+20 by 2x-10 and the frame is a constant 5 cm wider from the edge of the picture to the frame, than the area of the frame is defined as (x+30)(2x)-(x+20)(2x-10) = 30x+200.

If the width is equal to the length which I assume is true if the width is constant.

than x+30=2x, which means x = 30.

if this is true than 30(30)+200 = 1100cm^2

Answer: 180 degrees

Step-by-step explanation: I think

Answer:

it's not 180

Step-by-step explanation:

you have to add 105 + 53. then you get that number and subtract it from 180, that's your answer

Answer: i got ur back man

Step-by-step explanation:

There are four inputs: {-1, 0, 1 and 2}. Let x=-1 and find y. Let x = 0 and find y. And so on. You will find that only the input -1 produces the y-value predicted by the function f(x) = 4(5)^(2x).

Note that if you use a calculator to evaluate f(x), be certain to enclose "2x" inside parentheses: f(x) = 4(5)^(2x)

The probability of getting 2 the same colour is 29/72

Probability is the likelihood or chance that an event will occur.

Probability = Expected/Total outcome

Given that the bag is filled with 3 blue, 2 red, and 4 green marble, the total marble is 9

Pr(picking 2 blue and not replaced) = 3/9 * 3/8 = 1/8

Pr(picking 2 red and not replaced) = 2/9 * 2/8 = 1/18

Pr(picking 2 green and not replaced) = 4/9 * 4/8 = 2/9

Taking the sum of the probabilities = 1/8 + 1/18 + 2/9

The probability of getting 2 the same colour = 9+4+16/72 = 29/72

Hence the probability of getting 2 the same colour is 29/72

Answer:

6(x) + 8 [tex]\geq[/tex] 32

x = 4, 3, 2, 1, 0

Step-by-step explanation:

This is the answer because:

1) 8 more than 6 times a number is 6 times x + 8

6(x) + 8

2) "is at least 32" means 6(x) + 8 [tex]\geq[/tex] 32

3) x = 4, 5, 6, 7, 8 and etc. because -8 from +8 and 32

6(x) = 24

4) 6(4) = 24

5) x can equal anything less than 4

Therefore, the inequality is 6(x) + 8 [tex]\geq[/tex] 32 and x = 4, 3, 2, 1, 0

Answer:

[tex]Volume = 1906.14[/tex]

Step-by-step explanation:

Given

[tex]Height = 60ft[/tex]

[tex]Circumference = 20ft[/tex]

Required

Determine the volume

First, we need to determine the radius of the base using:

[tex]C = 2\pi r[/tex]

Substitute 20 for C

[tex]20 = 2 * 3.14 * r[/tex]

[tex]20 = 6.28 * r[/tex]

Solve for r

[tex]r = 20/6.28[/tex]

[tex]r = 3.18[/tex]  -- approximated.

The volume is then calculated as thus:

[tex]Volume = \pi r^2h[/tex]

[tex]Volume = 3.14 * 3.18^2 * 60[/tex]

[tex]Volume = 1906.14[/tex]

None of the given options is close to the volume of the silo

Answer:

(f + g)(x) = -x + 6

Step-by-step explanation:

Step 1: Define

f(x) = -3x + 6

g(x) = 2x

Step 2: Find (f + g)(x)

(f + g)(x) = -3x + 6 + 2x

(f + g)(x) = -x + 6

Answer:

-x +6

Step-by-step explanation:

f(x) = -3x + 6

g(x) = 2x

(f + g)(x)= Add the two functions

            = -3x + 6 + 2x

Combine like terms

            = -x +6

Answer:

$14.6

Step-by-step explanation:

1 cent = 0.01 dollar

4 cent = ( 4 × 0.01)

= 0.04 dollar

4 cent per a day: $0.04

1 year = 365 days

dollar per a year = ( 0.04 × 365)

= $14.6

Answer:

The length of the legs of the triangle is approximately 86.85 meters

Step-by-step explanation:

The requirement is to minimize the combined area of the two enclosures

The given parameters are;

The length of (perimeter) fencing available = 500 meters

The shape of the first enclosure = Square

The shape of the second enclosure = Triangle

The shape of the triangle = Isosceles right triangle

The area of the square = Side, S, squared = s²

The perimeter of the square = 4 × s

The area of the triangle = 1/2 × Base × Height = 1/2 × b × b= 1/2·b²

Where;

b = The lengths of the legs of the triangle

Given that the perimeter is 500 m, we have;

length of hypotenuse of triangle = √(b² + b²) =√(2·b²) = b·√2

∴ 500 - 4·s = b + b + b·√2 = 2·b + (√2)·b = b·(2 + √2)

b = (500 - 4·s)/(2 + √2)

∴ The area of the triangle = 1/2 × ((500 - 4·s)/(2 + √2))²

The area of the square + The area of the triangle = s² + 1/2 × ((500 - 4·s)/(2 + √2))²

At minimum value, we have;

d(s² + 1/2 × ((500 - 4·s)/(2 + √2))²/ds = 0, gives (Using online application)

[tex]2\cdot \left (s - \dfrac{8\cdot (125 - s)}{\left (2 + \sqrt{2} \right )} \right ) = 0[/tex]

From which we have, s = 500/(7 + 2·√2)

Differentiating again gives;

[tex]\dfrac{\mathrm{d} \left (2\cdot \left (s - \dfrac{8\cdot (125 - s)}{\left (2 + \sqrt{2} \right )} \right ) \right ) }{\mathrm{d} x} = 26 - 16 \cdot \sqrt{2} \approx 3.37[/tex]

Therefore, the point is a local minimum and the length of the legs of the triangle should be given as follows;

The length of the legs of the triangle = b = (500 - 4·s)/(2 + √2) = (500 - 4*(500/(7 + 2*√2)))/(2 + √2) ≈ 86.85

The length of the legs of the triangle ≈ 86.85 meters.

Answer:

Option (A)

Step-by-step explanation:

Domain of a function is defined by the x-values (input values) on the graph.

Range of a function is defined by the y-values (output values).

For a function having equation as,

y = x

Since, the given function is defined for all real numbers.

Domain of the function: {x | x ∈ R}

Range of the function: {y | y ∈ R}

Therefore, option (A) will be the answer.

Answer: $924

Step-by-step explanation:

From the question, we are told that if Raul has a sale of $280 he'll earn $40 as commission. This shows that he earns 40/280 = 1/7 as commission.

If Raul would like for his commission to be $132, he'll have to make a sale of:

Let the sale be represented by a

= 1/7 × a = $132

a = $132 × 7

a = $924

He'll have to make a sale of $924
