Leah wants to save money on a new computer. At the store near her the computer she wants is listed at a regular price of $400. On Saturday the store will have a sale & discount the computer by 30%. Shoppers who buy a computer that same Saturday before 9 AM will also receive an additional 10% off the sales price. How much will you pay without tax when she buys the computer that Saturday before 9 AM.

HELPPPP PLZZZ

Answer:

Step-by-step explanation:

Yesss

Answer:

17

Step-by-step explanation:

since you are given that x is 9 all you have to do is plug it in. So 1-2(9) 2 times 9 is 18 so 1-18=17

Answer:

5

Step-by-step explanation:

since the sides are the same size, then the equation should be combined into x+2=2x-3

then subtract an x from both sides: 2=x-3

then add 3 to both sides: 5=x

and you have your answer

hope this works

Answer:

x=5

Step-by-step explanation:

x+2=2x-3

-x on both sides=

2= x-3

then -2 on both sides

0= x-5

this means that x must be 5 so that positive 5- negative 5 equals 0 :)

Answer:

  A = 22.5°, 45°, 112.5°, 202.5°, 225°, 292.5°

Step-by-step explanation:

Use the angle reduction formula to reduce this to an expression involving only sine or cosine, then solve the resulting higher-degree polynomial.

   sin(3x) = 3sin(x) -4sin³(x)

Using the identity for cosine, we have the radical equation ...

  √(1 -sin²(A)) = 3sin(A) -4sin³(A)

Squaring both sides, we have ...

  1 - sin²(A) = 9sin²(A) -24 sin⁴(A) +16sin⁶(A)

Letting z = sin²(A), this is the cubic equation ...

  1 -z = 9z -24z² +16z³

  16z³ -24z² +10z -1 = 0

Solving this by the usual methods, we find its factors to be ...

  (2z -1)(8z² -8z +1) = 0

  8(2z -1)((z -1/2)² -1/8) = 0 . . . . quadratic in vertex form

Then the roots are ...

  z = (1 ±√(1/2))/2, z = 1/2

The angle solutions are ...

  A = arcsin(±√z)

Of course, these need to be adjusted to fall in the domain of interest, and checked for extraneous solutions.

For z = 1/2-√(1/8), the angles are ...

  A = ±22.5°  ⇒  22.5°, 157.5°, 202.5°, 337.5°

For z = 1/2, the angles are ...

  A = ±45°  ⇒  45°, 135°, 225°, 315°

For z = 1/2+√(1/8), the angles are ...

  A = ±67.5°  ⇒  67.5°, 112.5°, 247.5°, 292.5°

The angles that are in bold are the actual solutions; the others are extraneous.

_____

All of the above is "the hard way." A much simpler approach is to take advantage of the identity ...

  cos(a) -sin(b) = (1/2)·sin(b/2 -a/2 -π/4)·sin(b/2 +a/2 -π/4)

Then you can use the zero product rule to find (for a=A, b=3A) ...

  (3A/2 -A/2 -π/4) = nπ  ⇒  A = nπ +π/4  ⇒  45°, 225°

  (3A/2 +A/2 -π/4) = nπ  ⇒  A = (nπ +π/4)  ⇒  22.5°, 112.5°, 202.5°, 292.5°

Rewriting the equation as a function equal to zero, the solutions are the x-intercepts of the graph. In the attached, the x-axis is set to degrees.

  f(A) = cos(A) -sin(3A) = 0

B. 1/8

Step-by-step explanation:

Answer:

1) The y-intercept is -3.

2) An equation would be y = 2x - 3

Answer:

B; 50%

Step-by-step explanation:

Here, we want to calculate the percentage of women that will not fit in the driver’s seat

We proceed as follows;

We start with calculating the z-score of this;

That would be ;

(x-mean)/SD

in this case;

x = 34 inches

mean = 34 inches

SD = 1.4 inches

Thus, we have that;

(34-34)/1.4 = 0/1.4 = 0

when z-score is 0, we are at the center of the distribution

A z-score of 0 corresponds to exactly 50%

Answer: 840 people

Step-by-step explanation:

They surveyed 40 people in total and out of those 40, 21 said that sausage pizza was their favorite pizza.

The percentage of people who prefer sausage pizza is therefore:

= 21/40 * 100%

= 52.5 %

If there are 1,600 people in the festival and we assume that the sample is a representation of the people there, the estimated number of people who prefer sausage pizza will be:

= 52.5% * 1,600

= 840 people

The absolute value of -5.8 is 5.8

Answer:

$2.7

Step-by-step explanation:

We find the amount that was marked up

Jermaine buys T-shirts for $6 each and marks up the price by 45%.

The marked up amount = 45% × $6

= 45/100 × $6

= $2.7

Therefore, the amount Jermaine charges more for each T-shirt sold is $2.7

Answer:

1: 80% is 4/5 of the whole quantity

2: 1/5 is 20% of the whole quantity

3: 50% is 1/2 of the whole quantity

4: 1 is 100% of the whole quantity.

Answer:

Combined

Step-by-step explanation:

Explore the relationship between the general forms of variation :

Direct Variation :

x varies directly as y ; x = kx

Inverse Variation :

x varies inversely as y ; x = k/x

Joint : x varies jointly as y and Z ; x = kxz

combined :

x varies directly as y and inversely as z ; x = kx * 1/ ; x = kx/z

Where k is the proportionality constant.

In the equation given above :

We have a combination of joint and inverse variation : V = 5ng

V varies jointly as n and t and inversely as m

V α k * n * t * 1 / m

V = Knt /m

Where, k is proportionality constant.
