A shop is having a sale.
All items are reduced by 30%
Work out the sale price of an item normally priced at £110

Answers

Answer:

77

Step-by-step explanation:

10%=11

because you divide 110 by 10.

Then i would multiply that by 3, giving you 33

110-33=77

The sale price of an item normally priced at £110 is £77.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given that all items are reduced by 30% on a sale.

An item that normally priced at £110 reduced by 30%.

So, 30 percentage of £110

= 30% of £110

= 110×30/100

= 3300/100

= 33.

Therefore, the sale price of an item normally priced at £110 is £77.

After triangle ace is dilated by a factor of 5, it has an area of 100 square inches. What was its area before dilation?

Answers

Answer:

20in^2

Step-by-step explanation:

Since you multiply the original area of the triangle by the scale factor to get the new area, you can find the original area (before dilation) by dividing the dilated triangle's area by the scale factor. Since 100 is the area of the dilated triangle, and 5 is your scale factor, you do 100/5 to get the area of the triangle before it was dilated.

To catch a frisbee, a dog leaps into air with an initial velocity of 14 feet per second. Write a model for the height of the dog above the ground. After how many seconds does the dog land on the ground?

Answers

Answer:

Model: [tex]y = 14t+\frac{1}{2}(32.16)t^{2}[/tex]

The dog land on the ground after 0.8706 seconds.

Step-by-step explanation:

The model that said the height of the dog above the ground is a model of uniform acceleration motion, so it is:

[tex]y = y_0+v_0t+\frac{1}{2}gt^{2}[/tex]

Where [tex]y_0[/tex] is the initial height, [tex]v_0[/tex] is the initial velocity and [tex]g[/tex] is the gravity.

So, replacing [tex]y_0[/tex] by zero, [tex]v_0[/tex] by 14 feet per second and [tex]g[/tex] by [tex]32.16 ft/s^2[/tex], we get that the model  for the height of the dog above the ground is:

[tex]y = 14t+\frac{1}{2}(32.16)t^{2}[/tex]

Then, the time t when the dog land on the ground is calculated replacing [tex]y[/tex] by zero and solving for t as:

[tex]y = 14t+\frac{1}{2}(32.16)t^{2}\\0 = 14t+\frac{1}{2}(32.16)t^{2}\\0 =t (14 - 16.08t)[/tex]

Now, we have two possible solutions:

[tex]t=0[/tex] or [tex]14-16.08t=0[/tex]

Taking into account that t=0 is the time when the dog leaps into air, the time when the dog land on the ground is equal to 0.8706 seconds and it is calculated as:

[tex]14-16.08t=0\\14=16.08t\\\frac{14}{16.08}=t\\t=0.8706[/tex]

The amount of paint needed to cover a wall is proportional to its area. The wall is rectangular and has an area of 4z2 + 2z square meters. Factor this polynomial to find possible expressions for the length and width of the wall. (Assume the factors are polynomials.)

Answers

Answer:

2z(2z+1)

Step-by-step explanation:

Write the equation for the area and then factor the polynomial to find the possible expression for the length and width.

A = 4z2 + 2z The GCF of 4z2 and 2z is 2z.

= 2z(2z) + 2z(1) Write the terms as products using the GCF as a factor.

= 2z(2z + 1) Use the distributive property to factor out the GCF. Possible expressions for the dimensions of the wall are 2z m and (2z + 1) m.

The requried expression of the length and width is (2z + 1) and 2z.

What are the factors?

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,
As mentioned in the question, the amount of paint needed to cover a wall is proportional to its area.

The wall is rectangular and has an area of 4z² + 2z square meters. According to the question, we have factored this polynomial to find possible expressions for the length and width of the wall.
So,
Area =  4z² + 2z

Takin common 2z
Area = 2z × (2z + 1)

Comparing the above expression with
Area of rectangle = width × length

From comparison,

Length = (2z + 1)
Width = 2z

Thus, the requried expression of the length and width is (2z + 1) and 2z.

3x + 2x = 5x
5x + 7 = 32

O The graph of the function is negative on (3,co).

Answers

Answer:

The graph of the function is negative on (3,0)

Step-by-step explanation:

The limiting behavior of a function describes how a function behaves as x ⇒ ±∞. Its behavior is determined by the degree of a polynomial and the sign of its leading coefficient.

Since the function [f(x)] is an even degree polynomial with negative leading coefficient, then f(x) ⇒ -∞ as x ⇒ ±∞. The graph of the function is negative at the root. Since it has a root of 3, The graph of the function is negative on (3,0)

In a classroom there are 15 boys and 13 girls. One of the girls Samantha moved away. What percent of the classroom are girls after Samantha moved.

Answers

Answer: 44%

Step-by-step explanation: First, let's add up all the children in the classroom...

15 + 12 = 27

There's 15 boys, therefore have to divide 15 by 27...

15 ÷ 27 = 0.55 x 100 = 55%

Now, let's divided the total amount of girls...

12 ÷ 27 = 0.44 x 100 = 44%

44 + 55 = 99%

The perecent of girls in the classroom are 44%, I hope this helps!
