Answer:

$8.14

Step-by-step explanation:

Given data

Cost of surfboard= $22

Mark up = 37%

Required

The amount of the markup

let us find 37% of $22

=37/100*22

= 0.37*22

= $8.14

Hence the amount of the markup is $8.14

Answer:

Y = 5 - 2/x

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

You want to isolate x so first, you have to multiply the whole equation by 1/4 so it will look like 1/4(2y+4/x=10). Simplify this to get 1/2y+x=5/2. You want to isolate x, so you have to subtract 1/2 from each side, this will make the equation x=5/2-1/2. Simplify this to get x=4/2 which can also be simplified to x=2. Therefore, the answer is x=2

Answer:

4.75*100=475

Step-by-step explanation:

Answer:  The answer is 475 cm long.

Step-by-step explanation:

Since his bedroom is 4.75 meters long, it would be 475 cm.

Answer:

Step-by-step explanation:

2x^2+5x-4=0

x = [-5 ± √(5^2-4(2)(-4))]/[2(2)]

= [-5 ± √57]/4

= -1.25+0.25√57, -1.25-0.25√57

Step-by-step explanation:

If Brooke multiplied 3 by 9 and obtained 17 ; then Brooke is definitely wrong

3 * 9 = exactly 27

However, for approximation sake ;

We could round 9 to 10 ; and multiply 10 by 3

10 * 3 = 30 ; this gives an approximate solution for the multiplication problem ;

3 * 9 = exactly 27 or approximately 30

Answer:

A

Step-by-step explanation:

I think you are in geometry I learned this a little back...

It's hard to explain but basically one side is just (n) another is (n(square root sign))and another is (2n.)    

So the answer Is a because in this case (n) is 4

Answer:

5(3x+7y)

Step-by-step explanation:

In able to factor, it would require to find the least common number between x and y. In this scenario, it would be 5.

Answer:

You're going to get 5(3x + 7y)

Step-by-step explanation:

Simplifying

15x + 35y

Factor out the Greatest Common Factor (GCF), '5'.

5(3x + 7y)

Final result:

5(3x + 7y)

Answer:This is a linear equation.

y = mx+b

y is the total cost.

The slope m is the rate: that's 9 dollars per hour.

x is the number of hours.

b is the initial value: that's 16 dollars.

y = 9x+16

The problem states that the cost was 79 dollars.

Substitute that for y and solve for x.

79 = 9x+16

63 = 9x

x = 7 hour

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

80-17=63

63/7  = 9

7 times 9 = 63

Answer:

[tex](\frac{3}{2},102)[/tex]

Step-by-step explanation:

Given

[tex]f(x)=88x^2-264x+300[/tex] --- Missing from the question

Required

The symmetry

First, we express f(x) as: [tex]f(x) = a(x - h)^2 + k[/tex]

Where the symmetry is: (h, y) and x = h

Equate f(x) to 0

[tex]88x^2-264x+300 = 0[/tex]

Subtract 300 from both sides

[tex]88x^2-264x+300 - 300= 0 - 300[/tex]

[tex]88x^2 - 264x= - 300[/tex]

Factorize

[tex]88(x^2 - 3x) = -300[/tex]

On the left-hand side, the coefficient of x is -3.

Divide by 2 and add the square to both sides.

So, we have:

[tex]88(x^2 - 3x) + (\frac{3}{2})^2 = -300 + (\frac{3}{2})^2[/tex]

Multiply the new terms by 88 (to make it factorizable)

[tex]88(x^2 - 3x ) +88* (\frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]

Factorize

[tex]88(x^2 - 3x + (\frac{3}{2})^2) = -300 + 88 * (\frac{3}{2})^2[/tex]

The quadratic expression in the bracket is a perfect square. This gives:

[tex]88(x - \frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]

[tex]88(x - \frac{3}{2})^2 = -300 + 88 * \frac{9}{4}[/tex]

[tex]88(x - \frac{3}{2})^2 = -300 + 22 * 9[/tex]

[tex]88(x - \frac{3}{2})^2 = -102[/tex]

Add 102 to both sides

[tex]88(x - \frac{3}{2})^2 +102= -102 + 102[/tex]

[tex]88(x - \frac{3}{2})^2 +102= 0[/tex]

Equate to y

[tex]y = 88(x - \frac{3}{2})^2 +102[/tex]

Recall that:

The symmetry is: (h, y)

By comparison with [tex]f(x) = a(x - h)^2 + k[/tex] and x = h

[tex]h = \frac{3}{2}[/tex]

So: [tex]x = \frac{3}{2}[/tex]

Substitute [tex]x = \frac{3}{2}[/tex] in [tex]y = 88(x - \frac{3}{2})^2 +102[/tex]

[tex]y = 88(\frac{3}{2} - \frac{3}{2})^2 +102[/tex]

[tex]y = 88(0)^2 +102[/tex]

[tex]y = 0 +102[/tex]

[tex]y = 102[/tex]

So, the symmetry is: [tex](\frac{3}{2},102)[/tex]

Answer:

B. f(x) = -x + 2

Step-by-step explanation:

First, you find the point on the y-axis which is (0,2) in this problem.

This will be your b in y = mx+ b

Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.

This will be your m in y = mx + b

But we don't write the 1 so it will just be -x

Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2

Answer:

y=1.8

Step-by-step explanation:

first change the fraction into a decimal.

4/5 =0.8

plus the 0.8 to both sides

y=1.8

Answer:

[tex]y - \frac{4}{5} + \frac{4}{5} = 1 + \frac{4}{5} \\ y = \frac{5 + 4}{5 } \\ y = \frac{9}{5} [/tex]
