A radio set was sold for $570 at a loss of 25% on the cost price. Find the cost price​

Mathematics
1 answer:
stich3 [128]3 years ago
5 0

Answer:

$760.

Step-by-step explanation:

25 % = 0.25 as a decimal fraction.

Let x be the Cost price, then

x - 0.25x = 570

0.75x = 570

x = 570/0.75

x = 760.

Alchen [17]

Answer:

28 feet

Step-by-step explanation:

We know that the perimeter of a square is 2l + 2w, where l is the length and w is the width.

We also know that the perimeter of a triangle is all of its sides added up.

Since the perimeters will be equal to each other, we can make both of these statements an equation that are equal to each other.

Basically:

(3x - 3) + (3x - 3) + (x - 3) + (x - 3) = (2x - 1) + (2x - 1) + (2x)

We can combine like terms to get a <em>less scary</em><em>  </em>equation.

8x - 12 = 6x - 2

Our goal is to now isolate x so we can find it's value.

Add 2 to both sides:

8x - 10 = 6x

Subtract 6x from both sides:

2x - 10 = 0

Add 10 to both sides:

2x = 10

Divide both sides by 2:

x = 5

Now we know the value of x, however, our work isn't done. They want to know the perimeter, so we need to substitute x in as 5.

Let's do it on the triangle.

6x-2 (remember, this is our simplified version of the triangle)

6(5) - 2\\\\30 - 2\\\\28

Hope this helped!

It gets you closer to your answer.
Ex: 11×2-- Round 11 to 10 and then multiply and get 20. But if you get some answer like 50, you know it is wrong. But the answer is 23

A toy rocket is launched straight up from the top of a building. The function that models the height as a function of time is h(
kicyunya [14]

Answer: 50 ft

Step-by-step explanation:

The correct function is h(t)=-16t^2+200t+50.

Hi, to answer this question we simply have to replace t =0 in the function given:

h(t)=-16t^2+200t+50.

h (0) = -16t^2+200t+50.

h(0) = 50

When the time is 0, the rocket is at the top of the building.

The rocket was launched from a 50 ft height.

Feel free to ask for more if needed or if you did not understand something.
