A store purchased a plasma screen TV for $770 and marked it up 150%. During a sale, the store marked it down 20%. What was the discount price on the plasma screen TV?​

Answer:

I'm like 99.8 percent sure it's b5

Answer:

B) y = 5

Step-by-step explanation:

10/y = 8/4

8y = 40

y = 5

Answer:

x ≈ 9.5 , y ≈ 15.3

Step-by-step explanation:

sin32° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{18}[/tex] ( multiply both sides by 18 )

18 × sin32° = x , then

x ≈ 9.5 ( to the nearest tenth )

cos32° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{y}{18}[/tex] ( multiply both sides by 18 )

18 × cos32° = y , then

y ≈ 15.3 ( to the nearest tenth )

Answer:

B. f(x) = 8x + 2

Step-by-step explanation:

You can start by checking the first answer

f(x) = 8x + 2

Use the first row of numbers

Use x as the numbers in the 'In' column

f(x) is the numbers in 'Out' column

Therefore:

8x + 2

8(-4) + 2 = - 30

-32 + 2 = 30

This statement is correct

Therefore the correct answer is A.

Answer:

The length of the garage on the drawing is 22 cm

Step-by-step explanation:

The scale of the scale drawing = 11 centimeters: 5 meters

The actual length of the garage = 10 meters

The length of the garage in the drawing is found as follows;

5 meters = 500 centimeters

10 meters = 1,000 centimeter

Therefore, the scale of the drawing = 11 cm : 5 m = 11 cm : 500 cm

Let 'a' represent the length of the garage on the drawing, we have;

a : 1,000 cm = 11 cm : 500 cm

Therefore;

[tex]\dfrac{a}{1,000 \ cm} = \dfrac{11 \ cm}{500 \ cm}[/tex]

[tex]a= 1,000 \ cm \times \dfrac{11 \ cm}{500 \ cm} = 2 \ cm \times 11 = 22 \, cm[/tex]

The length of the garage on the drawing, a = 22 cm.

Answer:

x<5

Step-by-step explanation:

−2(x−7)>4

Step 1: Simplify both sides of the inequality.

−2x+14>4

Step 2: Subtract 14 from both sides.

−2x+14−14>4−14

−2x>−10

Step 3: Divide both sides by -2.

−2x ÷ −2 > −10 ÷ −2

x<5

Step-by-step explanation:

Given:

The height of the swipe card in feet after t seconds is

[tex]h(t)=-3t^2+15t+18[/tex]

To find:

The maximum height of the swipe card and the time at which it reaches this height.

Solution:

We have,

[tex]h(t)=-3t^2+15t+18[/tex]

Here, leading coefficient is -3, which is negative. It means it is a downward parabola and the vertex of the downward parabola is the point of maximum.

If a quadratic function is [tex]f(x)=ax^2+bx+c[/tex], then the vertex is

[tex]Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)[/tex]

In the given function, we get

[tex]a=-3,b=15,c=18[/tex]

Now,

[tex]-\dfrac{b}{2a}=-\dfrac{15}{2(-3)}[/tex]

[tex]-\dfrac{b}{2a}=2.5[/tex]

Putting t=2.5 in the given function, we get

[tex]h(2.5)=-3(2.5)^2+15(2.5)+18[/tex]

[tex]h(2.5)=36.75[/tex]

So, the vertex of the given parabola is at (2.5,36.75).

Therefore, the maximum height of the swipe card is 36.75 feet and it reaches this height after 2.5 seconds.

segments EA and DG

Step-by-step explanation:

A diameter is when a line segment crosses the center of the circle and its endpoints lie on the circle. Both segments EA and DG satisfy the definition of a diameter.

Answer:

EA and DG

Step-by-step explanation:

For it to be a diameter, it has to pass through the center (point H) and touch both sides of the circle.

The ones that work for that are EA and DG

Step-by-step explanation:

Given

Shape: Quadrilateral ABCD

Transformations:

180 degrees rotation

3 units left

7 units up

Required

Determine A′B′C′D

The coordinates of ABCD is not given; So, I will solve generally.

Assume the coordinates of ABCD is (x,y)

When (x,y) is rotated 180 degrees, the new point is: (-x, -y)

Solving further:

Translation 3 units left

When a point (x,y) is translated b units left, the new point is (x - b, y).

So:

[tex](-x, -y) ====> (-x - 3, -y)[/tex]

Translation 7 units up

When a point (x,y) is translated h units up, the new point is (x, y + b).

So:

[tex](-x - 3, -y) ====> (-x - 3, -y + 7)[/tex]

Assume that the coordinates of A in ABCD before translation is (2,6).

i.e. A = (2,6)

The image A' will be:

[tex]A' = (-2-3,-6+7)[/tex]

[tex]A' = (-5,1)[/tex]

Given

there are 4 sandwiches that each measures 12 inches

If they were cut into

[tex]3\ \dfrac{2}{3}\ in.=\dfrac{3\times 3+2}{3}=\dfrac{11}{3}\ in.[/tex]

Now, it becomes

[tex]\Rightarrow \text{No of sandwiches}=\dfrac{4\times 12}{\frac{11}{3}}=\dfrac{4\times 12\times 3}{11}=13.09\approx 13[/tex]

Now, there are 13 sandwiches
