Problem page the length of a rectangle is four times its width. if the perimeter of the rectangle is 70 cm , find its area.

1 answer:

5 0

So we can call the width of the rectangle x.
So then the length would be 4x.
The perimeter would then be 10x.
Since the perimeter is 70, we can say 70 = 10x.
And then simplify that to 7 = x.
So the length of a rectangle would be 28 cm, and the width would be 7.
So to find the area, just multiply length by width.
28*7 = 196 square cm
So the rectangle's area is 196 square cm.

A taxi ride costs p40.00 for the first 500 meters and each additional 300 meters or a fraction there of adds p3.50 to the fare.u

Zarrin [17]

The function which represents the taxi fare in terms of distance d in meter is f(d) = 3.50 × $\frac{d-500}{300}$ + 40 .

According to the question,

For first 500 meters cost is 40.00 and For each additional 300 meters cost is 3.50 .

Let, the total distance of taxi ride = d meters

Now, representing the equation of taxi fare in terms of distance when distance is less than 500

taxi fare = 3.50 × $\frac{d-500}{300}$ + 40

∴ f(d) = 3.50 × $\frac{d-500}{300}$ + 40

What is 4|2y-3|-1=11

umka2103 [35]

<span>implifying 4[2y + -3] + -1 = 11 Reorder the terms: 4[-3 + 2y] + -1 = 11 [-3 * 4 + 2y * 4] + -1 = 11 [-12 + 8y] + -1 = 11 Reorder the terms: -12 + -1 + 8y = 11 Combine like terms: -12 + -1 = -13 -13 + 8y = 11 Solving -13 + 8y = 11 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '13' to each side of the equation. -13 + 13 + 8y = 11 + 13 Combine like terms: -13 + 13 = 0 0 + 8y = 11 + 13 8y = 11 + 13 Combine like terms: 11 + 13 = 24 8y = 24 Divide each side by '8'. y = 3 Simplifying y = 3</span>

It's due todayyyyyyy (;ŏ﹏ŏ)

Thepotemich [5.8K]

The correct answer are

Sue interest : 169.6061952

Bill interest: 189.9131472

B. Bill will get more interest then sue

Explain

Sue principal balance p= 2300

Interest for 3 years so t= 3

Interest is compounded yearly n= 1

R= 2.4%

A= 2300(1+2.4/100)^3 = 2300(1+0.024)^3 = 2300 x (1.024)^3 = 2469.6061952

Interest for 3 year is A-p= 2469.6061952 -2300

169.6061952

Bill principle p= 1800

Interest for 3 years t= 3

Interest compounded so n= 1

R= 3.4%

A= 1800(1+3.4/100)^3 = 1800 (1+0.034)^3 = 1800 (1.034)^3 = 1989.9131472

Interest in 3 yrs = 1989.9131472 - 1800 =

189.9131472

For B is below

Hopefully this help you :D
