A market stall holder bought a variety of coloured 'hoodies' to sell. Each hoodie costs the stall holder $20 and she intends to sell them to the public at a mark up of 65%

1) What profit does the stall holder make on the sale of each hoodie?

Answer:

n= 7.5

Step-by-step explanation:

So to get the answer to this equation, we have to create different equivalent equations, in the base equation so that in the end all bases are equivalent to solve for n.

Exact Form:

7/2

Decimal Form:

3.5

Mixed Number Form:

3 1/2

Hope this was helpful! Have a great day! :)

Answer:

n = 4

Step-by-step explanation:

Properties of Exponents

We are required to solve the following equation:

[tex]\displaystyle 7^7\cdot 7^5=\frac{(7^n)^4}{7^4}[/tex]

Operating:

[tex]\displaystyle 7^{7+5}=\frac{7^{4n}}{7^4}[/tex]

[tex]\displaystyle 7^{12}=7^{4n-4}[/tex]

Equating the exponents:

4n - 4 = 12

Adding 4:

4n = 16

Dividing by 4:

n = 4

Answer:

$195

Step-by-step explanation:

To solve a percent problem, you can use the equation:     part            %

                                                                                                -------    =    -----

                                                                                               whole         100

You want to find 30 percent, so the % would be 30. You also want to find 30% of 150, so the whole would be 150 and the part would be x. Cross multiply to get     100x = 4500. Then, divide 4,500 by 100. The equation should look like this:  x = 45. Add 45 to $150 to get $195. So Aaron has $195 at the end of the week.

Step-by-step explanation:

Putting value of n = 3 in equation

(3)2 + 3 + 5

9 + 8

= 17

Answer:

17

Step-by-step explanation:

Given

n² + n + 5 ← substitute n = 3 into the expression

= 3² + 3 + 5

= 9 + 3 + 5

= 17

Answer:

y = [tex]\frac{7}{2}[/tex] x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

- 7x + 2y = 8 ( add 7x to both sides )

2y = 7x + 8 ( divide all 3 terms by 2 )

y = [tex]\frac{7}{2}[/tex] x + 4 ← in slope- intercept form

Answer:

5.82 x 10^6

Step-by-step explanation:

Answer:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

5.82 ×10 ^6.

Answer:

[tex]25.1\ \text{inches}^2[/tex]

[tex]56.5\ \text{inches}^2[/tex]

[tex]69.7\ \text{inches}^2[/tex]

Step-by-step explanation:

The length of the pipe is given by the function

[tex]L=119.75\sqrt{A}[/tex]

where A is the area

[tex]A=(\dfrac{L}{119.75})^2[/tex]

For [tex]L=600\ \text{in}[/tex]

[tex]A=(\dfrac{600}{119.75})^2\\\Rightarrow A=25.1\ \text{inches}^2[/tex]

Area watered when L = 600 inches is [tex]25.1\ \text{inches}^2[/tex]

For [tex]L=900\ \text{in}[/tex]

[tex]A=(\dfrac{900}{119.75})^2\\\Rightarrow A=56.5\ \text{inches}^2[/tex]

Area watered when L = 900 inches is [tex]56.5\ \text{inches}^2[/tex]

For [tex]L=1000\ \text{in}[/tex]

[tex]A=(\dfrac{1000}{119.75})^2\\\Rightarrow A=69.7\ \text{inches}^2[/tex]

Area watered when L = 1000 inches is [tex]69.7\ \text{inches}^2[/tex]

I’m pretty sure 17.3 because of you do a^2+b^2=c^2 you get a^2= 10 square root 3 and that in a decimal is 17.3205

Answer:

8

Step-by-step explanation:

Answer:

86%

Step-by-step explanation:

angles in the triangle add up to 180

so we add 75% and 19%

to get 94%

then we subtract 180 by 94%

to get 86%

Answer:

471

Step-by-step explanation:

do to the number in the tenths place not being higher than 5 all number past the decimal become zero and the whole number stay the same

3 hours and 43 minutes = 223 minutes

Step-by-step explanation:

Answer: x=7/2, x=-3

Step-by-step explanation:

First lets do look at it without the absolute value marks

4x-1=13

4x=14

x=7/2

Now lets do the same but assume 13 is negative,

4x-1=-13

4x=-12

x=-3

Answer:

3ab(c+2a)

Step-by-step explanation:

Given data

3abc+6a²b

we can see that 3, a, and b are common between the two terms

so let us factor them out

3ab(c+2a)

Hence the factored form is

3ab(c+2a)

Answer:

do it urself sorry i letterely dont know

Step-by-step explanation:

Answer:

a = -8

Step-by-step explanation:

g(a) = -37

g(a) = 4a - 5

g(a) = 4a - 5

-37 = 4a - 5

-37 + 5 = 4a

-32 = 4a

a = -32/4

a = -8

Answer:

Yes, it is proportional.

Step-by-step explanation:

Anything with "A =" is always going to be proportional.

Answer:

I...think so?

if you isolate b then b = [tex]\frac{A}{4}[/tex] or [tex]\frac{1}{4}[/tex]

if you isolate A like already shown then A = 4b

Answer:

-1

0.30103m+0.477121n.

the answer is

0.39103m+0.477121n

Answer:

Step-by-step explanation:

First, add up the two numbers in the ratio to get 8. Next divide the total amount by 8, i.e. divide £40 by 8 to get £5. £5 is the amount of each 'unit' in the ratio.

To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3.

Answer:

-4

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(-16 + 8) / (-8 + 10)

-8 / 2

= -4

So, the slope is -4
