You are shopping and find a coat that is on sale for 30% off . It is regularly priced at $80 . Your friend tells you that she saw the same coat for $ 80 in another store, but it was 20 % off plus an additional 10% off . Will you save money by going to the other store ? Explain why or why not .

You are shopping and find a coat that is on sale for 30% off . It is regularly priced at $80 . Your friend tells you that she saw the same coat for $ 80 in another store, but it was 20 % off plus an additional 10% off . Will you save money by going to the other store ? Explain why or why not .

Answers

Answer:

No

Step-by-step explanation:

Because if the coat is 20% with an additional 10% off that would equal 30% which is equal to the 30% off at the current store so they're both giving out the same deal

Answer:

No, because %30 is taking more off a higher number. Rather than only taking %20 off of it than the %10 is taking off an amount on a smaller amount resulting in it taking off less.

Step-by-step explanation:

$80 * 0.3 (%30) = $24

$80 - $24 = $56

$80 * 0.2 (%20) = $16

$80 - $16 = $64

$64 * 0.1 (%10) = $6.4

$64 - $6.4 = $57.6

Li’s family is saving money for their summer vacation. Their vacation savings account currently has a balance of $2,764. The family would like to have at least $5,000. Which inequality can be used to determine the amount of money the family still needs to save? 2764 + x > 5000 2764 + x Greater-than-or-equal-to 5000 2764 + x Less-than-or-equal-to 5000 5000 + x > 2764

Answers

Answer:

B. 2764 + x Greater-than-or-equal-to 5000

Step-by-step explanation:

A. 2764 + x > 5000

B. 2764 + x Greater-than-or-equal-to 5000

C. 2764 + x Less-than-or-equal-to 5000

D. 5000 + x > 2764

Current balance of their account = $2,764

They need a balance of at least $5,000

At least in inequality means greater than or equal to

Let x = remaining balance to make at least $5,000

The inequality is

2764 + x greater than or equal to 5,000

The answer is B. 2764 + x Greater-than-or-equal-to 5000

The inequality that can be used to determine the amount of money she still needs to save is x ≥ $5000 - $2,764.

What inequality can be used to represent the amount that still needs to be save?

The following are inequality signs and what they mean:

> means greater than< means less than≥ means greater than or equal to ≤ less than or equal to

The inequality sign to be used is ≥.

The amount that still needs to be saved: x ≥ $5000 - $2764

Calculate the distance between the points f=(-8,5) and k=(-4,1) in the coordinate plane round your answer to the nearest hundredth

Answers

Answer:

5.66

Step-by-step explanation:

Given data

the coordinates are

f=(-8,5) and

x1= -8

y1= 5

k=(-4,1)

x2= -4

y2= 1

The distance can be expressed using the formula

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((-4+8)²+(1-5)²)

d=√((4)²+(-4)²)

d=√16+16)

d=√32

d=√32

d=5.656

Hence the distance between the points is 5.66

the width of a rectangle is 2 in less than its length the area is 24 square inches find the dimensions of the rectangle

Answers

Answer:

6,4

Step-by-step explanation:

Create a system of equations

l-2=w

w*l=24

Substitute

l-2*1=24

l=6

6-2=4

w=4

Dimensions of the rectangle are 6inch and 4 inch.

What is rectangle?

"Rectangle is a quadrilateral whose all  angles are right angle and opposite sides are parallel and equal in measurement."

What is dimensions?

" Dimension is measurement of any object such as length, width and height of any object."

What is area?

"Area is a space occupied by an object."

Let 'l' be the length of the rectangle.

According to the question,

Width = l - 2

Area= 24 square inches

Formula used

Area of a rectangle = length x width

[tex]24 = l[/tex] × [tex](l-2)[/tex]

⇒[tex]24[/tex] = [tex]l^{2} -2l[/tex]

[tex]l^{2} -2l -24=0[/tex]

⇒[tex]l^{2} -6l+4l -24 =0[/tex]

⇒[tex]l(l-6) +4(l-6) =0[/tex]

⇒[tex](l-6)(l+4) =0[/tex]

⇒[tex]l=6[/tex] or [tex]l= -4[/tex]

length cannot be negative.

Therefore, [tex]l=6[/tex]inch

⇒width = [tex]6-2[/tex]

⇒ width = 4 inch

Hence the dimensions of the rectangle are 6inch and 4 inch.

On a particular flight, the airline's income was $95,280 for a jumbo jet carrying 290 passengers. If a first-class ticket costs $680 and a coach ticket costs $288, how many of each ticket were sold for the flight?

Answers

Answer:

30 first-class tickets were sold and 260 coach tickets were sold.

Step-by-step explanation:

Let a first-class ticket be represented by f and let a coach ticket be represented by c.

On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:

[tex]f+c=290[/tex]

The total income was $95,280. Therefore:

[tex]680f+288c=95280[/tex]

We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:

[tex]85f+36c=11910[/tex]

From the first equation, we can subtract f from both sides:

[tex]c=290-f[/tex]

Substitute:

[tex]85f+36(290-f)=11910[/tex]

Distribute:

[tex]85f+10440-36f=11910[/tex]

Simplify:

[tex]49f=1470[/tex]

So:

[tex]f=30[/tex]

From the previous equation:

[tex]c=290-f[/tex]

Substitute:

[tex]c=290-30=260[/tex]

30 first-class tickets were sold and 260 coach tickets were sold.
