devi bought 7 skirts at x$ each n skirts at 12$ each 2n +1 at 15 each a nd 4 skirts at $3x find the total
nikitadnepr [17]

Answer:

$(19x + 42n + 15)

Step-by-step explanation:

Devi bought 7 skirts at $x each, n skirts at $12 each, (2n + 1) skirts at $15 each and 4 skirts at $3x each. Find the total cost of the skirts she bought.​

total cost of the skirt bought can be determined by adding the  total costs of each shirt bought

7 skirts at $x each = $7x

n skirts at $12 each = $12n

(2n + 1) skirts at $15 = (2n + 1) x 15 = 30n + 15

4 skirts at $3x each = $12x

7x + 12n + 30n + 15 + 12x

combine like terms

19x + 42n + 15

Find an equation equivalent to r = 10 sinθ in rectangular coordinates
Flura [38]

Answer:

x^{2} + y^{2} - 10\cdot y = 0

Step-by-step explanation:

The following expressions are used to transform from polar into rectangular form:

r = \sqrt{x^{2}+y^{2}}

\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}

Now, the variables are substituted and equation is finally simplified:

\sqrt{x^{2}+y^{2}} = 10\cdot \frac{y}{\sqrt{x^{2}+y^{2}} }

x^{2}+y^{2} = 10\cdot y

The equivalent equation in rectangular coordinates is:

x^{2} + y^{2} - 10\cdot y = 0

(3.8 x 10 ^ -6) x (2.37 x 10 ^ -3)<br><br> Enter the answer in science notification
Black_prince [1.1K]

Multiply the coefficients and the powers of 10 with each other:

(3.8 \times 10^{-6}) \times (2.37 \times 10^{-3}) = (3.8\times2.37) \times (10^{-6} \times10^{-3})

The numeric part simply yields

3.8\times2.37 = 9.006

As for the powers of 10, you have to add the exponents, using the rule

a^b \times a^c = a^{b+c}

So, we have

10^{-6} \times10^{-3} = 10^{-6-3} = 10^{-9}

So, the final answer is

9.006\times 10^{-9}

Please I really need help
Zepler [3.9K]

Answer:

\bold{q(x)=\{5x-12\}+\{-6x-12\}}

Step-by-step explanation:

Where it says q(x)=a(x)+b(x), it simply means: the answer to q(x) is  adding both functions, 5x-12 (a(x)) and -8\times2-6x+4 (b(x)).

First, let us solve a(x)

5x-12

As we can see, this equation cannot be further simplified. So, this is our final result for this problem.

Next, let us solve b(x)

-8\times2-6x+4

Multiply -8 and 2

-8 × 2 = -16

[remember your integer rules: a negative times a negative is a positive.]

So we have:

-16-6x+4

Combine like terms: -16 and 4 are terms that are alike based on them being integers, but -6x id not because it contains a variable. When you combine you are adding.

-16 + 4 = -12

Now we have:

-6x-12

As we can see, this equation cannot be further simplified. So, this is our final result for this problem.

Lastly, combine these results.

q(x)=\{5x-12\}+\{-6x-12\}

Therefore, that is the answer.
