Answer!! What is Simplified?

Answer:

a). 21.2

Step-by-step explanation:

square has 4 sides

one side = 60÷4 = 15

Use pythogoras theorem to find the hypotenuse thus the diagonal of the square.

x = √(15² + 15²)

x = √(225 + 225)

x = √450

x = 21.21 (2 dp)

Answer:

4 ft = width of walkway

Step-by-step explanation:

It helps if you can draw a figure.

Let x = width of walkway

Length of pool + walkway = (2x + 15)

Width of pool + walkway = (2x + 15)

area of pool and walkway together = (2x + 15)(2x + 15) = [tex]4x^{2} = 60x + 225[/tex]

Area of the pool = 15(15) = 225

Now,

The area of the walkway = area of pool and walkway together - area of pool

304 = 4[tex]x^{2}[/tex] + 60x + 225 - 225

304 = [tex]4x^{2}[/tex] + 60x

4[tex]x^{2}[/tex] + 60x - 304 = 0

4([tex]x^{2}[/tex] +15x - 76) = 0

4(x - 4)(x + 19) = 0

x = 4    x = -19

-19 must be discarded because a length cannot be negative

Therefore x = 4 ft = width of walkway

Answer:

$5.40

Step-by-step explanation:

First, figure out the cost of the items with tax; for Tommy we have 20*0.08 = 1.6, add that 1.6 to the 20 and his purchase is $21.6, for John we have 25*0.08 = 2, add 2 to his 25 and his purchase is $27. To find the difference we subtract 27-21.6 = 5.4 or $5.40

Answer:

pythagorean theorem is a^2 +b^2=c^2

Step-by-step explanation:

Answer:

The speed of the wind is 4.8 km/hr

Step-by-step explanation:

The parameters of the motion of the man are;

The distance the man travels in the given time while moving against the wind = 12 km

The distance the man travels in the giving time while going with the wind = 28 km

From search online for of a similar question, we have;

The speed with which the man is cycling = 12 km/hr

Let. 't', represent the time the travels each distance, let 'w', represent the speed of the wind and let 'v' represent the speed of the man, we have;

Time, t = Distance, d/(Velocity, v)

The resultant speed of the man when he travels against the wing = v - w

The resultant speed of the man when he goes in the the wing = v + w

Therefore, we have;

12/(v - w) = 28/(v + w)

12·v + 12·w = 28·v - 28·w

12·w + 28·w = 28·v - 12·v = 16·v

40·w = 16·v

∴ w = (16/40) × v = (2/5) × v

The speed with which the man is cycling = 12 km/hr

∴ The speed of the wind, w = (2/5) × v = (2/5) × 12 km/hr = 4.8 km/hr

The speed of the wind = 4.8 km/hr.

(x-2)(x-5)=0

x=2 or x=5

Answer:

Step-by-step explanation:

x2−7x+10=0

Step 1: Factor left side of equation.

(x−2)(x−5)=0

Step 2: Set factors equal to 0.

x−2=0 or x−5=0

x=2 or x=5

Answer: 600 ml

Step-by-step explanation:

Let the volume of the solution be represented by x.

Therefore, we can form an equation based on the information given which will be:

= 4% × x = 24.

4/100 × x = 24.

0.04 × x = 24

0.04x = 24

x = 24/0.04

x = 600

The volume of the solution is 600ml

The answer is

m = 4

Answer:

20 miles

Step-by-step explanation:

x = break even miles

x = 20 miles

Answer:

Answer: D $15

Step-by-step explanation:

Answer:

D. y = 2x -3

Step-by-step explanation:

The equation of a line in slope-intercept form is

y = mx + b

We need to find m, the slope, and b, the y-intercept.

We can find those two numbers from the graph.

We look in the graph and see that the y-intercept, b, is -3.

Now we have y = mx - 3.

Now we look for the slope. Start at (0, -2). We need to go vertically and horizontally to the next point that is easy to read. We see that point (1, -1) is on a grid intersection making it easy to read, so we will use that point.

Go up 2 units. That is a rise of positive 2. Now go right 1 unit. That is a run of positive 1.

slope = rise/run = 2/1 = 2

m = 2, so now we have

y = 2x - 3

Answer: D. y = 2x -3

Answer:

329.91 cm^2

Step-by-step explanation:

A ring-shaped region is shown below. Its inner radius is 8m, and its outer radius is 11m. 8m 11m Find the area of the shaded region. Use 3.14 for π. Do not round your answer.

Your answer

Given data

inner radius= 8cm

area= πr^2

area= 3.142*8^2

area= 3.142*16

area= 50.272 cm^2

outer radius= 11cm

area= πr^2

area= 3.142*11^2

area= 3.142*121

area= 380.182 cm^2

Hence the area of the shaded part is

=380.182-50.272

=329.91 cm^2

Step-by-step explanation:

25m + 10b = 400

not enough info to solve for m or b. but that's the equation you would use.

Answer:the greatest number of shirts she can buy = 8

Step-by-step explanation:

Amount of money Olivia  has =$90

cost of pair of jeans =$22

such that if she buys the pair of jean, Money left to buy shirts = $90-$22= $68

If 1 Shirt= $8

Number of shirts she can buy with $68 = $68/$8=  8.5= 8 1/2

Therefore the greatest number she can buy = 8 shirts.

The factored form of the related polynomial function is    [tex](x-1)(x+7).[/tex]

Polynomial function is a function that involves non-negative integer powers or positive integer exponents of a variable in an equation like the quadratic equation, cubic equation.

We have,

In the graph given in question, we can see that [tex]x-[/tex]intercepts the axis twice.

And graphs behave differently at various [tex]x-[/tex]intercepts. Sometimes the graph will cross over the [tex]x-[/tex]axis at an intercept and other times the graph will touch the [tex]x-[/tex]axis and bounce off.

Now, in graph;

The [tex]x-[/tex]intercept at [tex]x=1[/tex], i.e. the solution of the [tex]x-1=0[/tex] and passes through the axis.

Now,

The [tex]x-[/tex]intercept at [tex]x=7[/tex]  is the solution of [tex]x-7=0[/tex] and again passes through the axis.

So, from the above statements we can say that the factored form of the related polynomial is [tex](x-1)(x+7).[/tex]

Hence, we can say that the factored form of the related polynomial function is    [tex](x-1)(x+7).[/tex]
