A salesperson at a jewelry store earns 3% commission
each week. Last week, Heidi sold $720 worth of jewelry.
a. How much did she make in commission?
b. How much did the jewelry store make from her sales?

Answer:

C

Step-by-step explanation:

The actual average time = 81.5 minutes

The correct answer is an option (B) 81.48 minutes

"percent error = [(estimated value - actual value) / (actual value)] × 100"

For given example,

percent error (e) = 3%

estimated average time spent (x) = 84 minutes

We need to find the actual average time spent (y)

Using the formula of percent error,

⇒ e = [(x - y)/y] × 100

⇒ 3 = (84 - y)/y  × 100

⇒ (84 - y)/y = 3/100

⇒ (84 - y) / y = 0.03

⇒ 84 - y = 0.03y

⇒ 84 = 0.03y + y

⇒ 84 = (1.03)y

⇒ y = 81.5 minutes

Therefore, the actual average time = 81.5 minutes

The correct answer is an option (B) 81.48 minutes

Answer:

400 meters

Step-by-step explanation:

First, divide 3,200 by 24 to find the rate, which is 133.3 (repeated).

Now, multiply 133.3 by 3, which is your answer! 133.3*3=399.9. 399.9 is extremely close to 400, so we can just round it to that.

Answer:

The quadratic equation is

3x^2+ 27x + 60

Step-by-step explanation:

Here, we have the roots -5 and -4 and the leading coefficient of 3

Mathematically, we simply have this done to the roots;

x = -5 implies x+ 5

x = -4 implies x + 4

The product of this two will be;

(x + 5)(x + 4)

= x^2 + 5x + 4x + 20

= x^2 + 9x + 20

we add the leading coefficient

that would be;

3(x^2 + 9x + 20)

= 3x^2 + 27x + 60

Step-by-step explanation:

Answer:

A. 6.95 + 8c = 24.95

Step-by-step explanation:

Well, the answer to this question is A is because if we carefully look at this problem, then we can see that Karen bought a canvas for $6.95 and she also bought 8 tubes of paint. Now, the total amount of money that she spent is $24.95.

So, in this problem, our $6.95 is the cost for the canvas that she bought whereas when she mentions buying 8 tubes of paint, she doesn't mention how much each tube of paint costs so, the cost for one tube of paint is unknown and thus, it is a variable.

So, in conclusion, the answer to this question is definitly, A. 6.95 + 8c = 24.95

Answer:10x^2-27x+5. 10x2−27x+5 10 x 2 - 27 x + 5. For a polynomial of the form ax2+bx+c a x 2 + b x + c , rewrite ...

Step-by-step explanation:

The solution of the equation:

x = -0.28 to the nearest tenth.

x = 4.53 to the nearest tenth.

For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.

Given:

A quadratic equation,

4x²-27x-5 = -10x

Simplifying,

4x²-27x-5 + 10x = 0

4x²-17x-5 = 0

So,

x = {-(-17) ± √(289 + 80)}/8

x = (17 ± √369) / 8

When we take - sign,

x = - 0.276

x = -0.28 to the nearest tenth.

When we take + sign,

x = 4.526

x = 4.53 to the nearest tenth.

Therefore, the values are x = -0.28 and x = 4.53.

Answer:

The first five terms of the sequence

4 , 9 , 14 , 19 , 24

Step-by-step explanation:

Explanation:-

Given [tex]n^{th}[/tex] of the sequence

   aₙ = 5 n -1

Put n=1

 a₁ = 5(1)-1 = 5-1 =4

First term of the sequence = 4

Put n =2

 a₂ = 5(2) -1 = 10-1 =9

Second term of the sequence = 9

Put n=3

a₃ = 5(3)-1 =15-1 =14

Third term of the sequence = 14

Put n=4

a₄ = 5(4)-1 = 20 -1 = 19

Fourth term of the sequence = 19

Put n=5

a₅ = 5(5)-1 = 25-1 =24

Fifth term of the sequence = 24

Final answer:-

The first five terms of the sequence

4 , 9 , 14 , 19 , 24   this is an arithmetic progression
