The Width Of A Rectangle Is Two-thirds Of The Length. The Perimeter Of The Rectangle Is 15 Centimeters.

Answer 2

The length of the rectangle is given by the equation L = 4.5 cm

What is the Perimeter of a Rectangle?

The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P of rectangle = 2 ( Length + Width )

Given data ,

Let the perimeter of the rectangle be represented as P = 15 cm

Now , the equation will be

Let the length of the rectangle be L

Let the width of the rectangle be W

Now , width of a rectangle is two-thirds of the length

Substituting the values in the equation , we get

W = ( 2/3 ) L

And , Perimeter P of rectangle = 2 ( Length + Width )

Substituting the values in the equation , we get

15 = 2 ( L + ( 2/3 ) L )

On simplifying the equation , we get

15/2 = L + ( 2/3 )L

15/2 = 5L/3

15 = 10L/3

Multiply by 3 on both sides of the equation , we get

45 = 10L

Divide by 10 on both sides of the equation , we get

L = 4.5 cm

Therefore , the value of L is 4.5 cm

Hence , the length of the rectangle is 4.5 cm

Each morning, Stacey makes 20 cinnamon bagels for his customers at Barney's Bagels. Because of a recent increase in the popularity of cinnamon bagels, she has increased the number she bakes each morning by 80%. How many cinnamon bagels does Stacey now bake each day?

Answers

Answer: Stacey now bakes 36 cinnamon bagels.

Step-by-step explanation:

Given: Each morning, Stacey makes 20 cinnamon bagels.

She has increased the number she bakes each morning by 80%.

Number of cinnamon bagels Stacey bake = 20+80% of 20

= 20+ (0.80)x 20 [To remove % , divide number by 100, So 80%=0.08]

= 20+16 [(0.80)x 20=16 ]

= 36

Hence, Stacey now bakes 36 cinnamon bagels.

If John can paint half of a room in two-thirds of an hour, what part of the room can he paint in a full hour?

Answers

Answer:

0.75(3/4) part of the room

Step-by-step explanation:

Step one:

given data

we can express the given data mathematically as

John can paint 0.5room in 2/3 hours

let the part of the room he can paint in an hour be x

if he takes 2/3 hours to paint 0.5 room

then he will take 1 hour to paint x

cross multiply we have

x= 0.5/2/3

x=0.5*3/2

x= 1.5/2

x=0.75 part of the room

75/100= 15/20=3/4 part

if the solutions of p(x)=0 are -14 and 11, which function could be p?
(A) p(x)=x^2-3x-154

(B) p(x)=x^2-14x+11

(C) p(x)=x^2+14x+11

(D) p(x)=x^2+3x-154

Answers

Answer:d

Step-by-step explanation:

The required function is [tex]P(x)=x^2+3x+154[/tex]. So, option D is correct.

Important information:

The solutions of [tex]p(x)=0[/tex] are [tex]-14[/tex] and 11.

We need to find the function p(x).

Function:

If [tex]x=c[/tex] is a solution of [tex]p(x)=0[/tex], then [tex](x-c)[/tex] is a factor of p(x).

It means [tex](x+14)[/tex] and [tex](x-11)[/tex] are two factor of p(x).

[tex]P(x)=(x+14)(x-11)[/tex]

[tex]P(x)=x^2-11x+14x+154[/tex]

[tex]P(x)=x^2+3x+154[/tex]

Therefore, the correct option is D.

Alexandro received two quotes for new carpet for his home. The quote from Home Depot is $0.20 less per square foot than the quote from Lowe's. If Alexandro plans to buy 1,300 square feet of carpet, how do his total costs from the two companies compare? *

Answers

Answer:

Total cost as per Lowe's is $260 more than that of Home Depot.

Step-by-step explanation:

Given that:

Alexandro received two quotes for new carpet.

One from Home Depot and other from Lowe's.

Let quote from Home Depot = [tex]\$x[/tex] per sq foot

As per question statement,

The quote from Lowe's = [tex]\$x[/tex]+0.20 per sq foot

Alexandro plans to buy 1,300 square feet of carpet.

Total Cost as per Home Depot's quote = [tex]\$1300x[/tex]

Total Cost as per Lowe's = [tex]\$(x+0.20)\times 1300 = \$1300x + \$260[/tex]

Now taking the difference of the total cost:

Lowe's total cost - Total cost as per Home Depot.

[tex]\$1300x+\$260 - \$1300x \\\Rightarrow \$260[/tex]

So, the answer is:

Total cost as per Lowe's is $260 more than that of Home Depot.

Answer:

y = 2x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (3, - 1) into the partial equation

- 1 = 6 + c ⇒ c = - 1 - 6 = - 7

y = 2x - 7 ← equation of line

Can someone help me with this question it’s 7.55 x 4.5

Answers

Answer:

33.975

Step-by-step explanation:

If you are going to multiply this by hand, make sure that you add a zero to the end of 4.5 so that it is 4.50. Because there are four decimal places, you need to make sure your answer has four decimal places as well. Then add a row of zeroes to the bottom because anything times zero equals zero. Next, add a zero in the hundredths place and multiply 5 from 4.50 to 7.55. Then, do the same with the 4. Add all your numbers together and you should get 33.9750 or 33.975.
