The length of a rectangle is one more than twice its width. If its perimeter is 20 inches, what is its length and width?

Answers

Answer 1

Answer:

Let length be L

Width be W

L=1+2W

Perimeter(p) of rectangle is

P=2L+2W

But L = 1+ 2W and p= 20

:. 20 =2(1+2W) +2W

20=2+4W+2W

18=6W

Divide both sides by 6

W =3

2W+1=L

6+1=L

L=7

Hence, length and width are 7in and 3in respectively

(1) 2041 cm?
(2) 2241 cm?
(3) 2481 cm?
(4) 240 cm?

Answers

Answer:

A = 240π cm²

Step-by-step explanation:

Given that,

Height of a cylinder, h = 7 cm

Volume of the cylinder, V = 448π cm³

We need to find the total surface area of the cylinder.

The formula for the volume of the cylinder is given by :

[tex]V=\pi r^2 h\\\\r=\sqrt{\dfrac{V\pi }{\pi h}} \\\\r=\sqrt{\dfrac{448\pi }{\pi \times 7}} \\\\r=8\ cm[/tex]

The formula for the total surface area of the cylinder is given by :

[tex]A=2\pi r(r+h)\\\\A=2\pi \times 8\times (8+7)\\\\A=240\pi \ cm^2[/tex]

So, the total surface area of the cylinder is 240π cm².

Answer:

176.

Step-by-step explanation:

112 = 2*2*2*2*7

For a cube number there must be 3 or a multiple of 3 of each factor.

So we multiply  by 2*2 and 7 * 7 to give 2^6 * 7^3 which is 21952.

The answer is 4*49

= 176.

A citrus grower purchased 25 orange trees and 20 grapefruit trees for $290. The next week, at the same prices, the grower bought 20 orange trees and 30 grapefruit trees for $330. Find the cost of an orange tee and the cost of a grapefruit tree.

Answers

Answer:

The cost of an orange tree is $ 6 while that of a grapefruit tree is $

Step-by-step explanation:

Let x be the cost of an orange tree and y be the cost of a grapefruit tree. In the first week, the citrus grower purchased 25 orange trees and 20 grapefruit trees for $290, so 25x + 20y = 290 (1).

In the next week, the grower bought 20 orange trees and 30 grapefruit trees for $330. So, 20x + 30y = 330 (2)

From (2) y = (330 - 20x)/30 = (33 - 2x)/3

substituting y into (1), we have

25x + 20[(33 - 2x)/3] = 290

multiplying through by 3, we have

75x + 20(33 - 2x) = 870

expanding the bracket, we have

75x + 660 - 40x = 870

collecting like terms, we have

75x - 40x = 870 - 660

35x = 210

dividing both sides by 35, we have

x = 210/35

x = 6

substituting x = 6 into y, we have

y = (33 - 2x)/3

= (33 - 2(6))/3

= (33 - 12)/3

= 21/3

= 7

So the cost of an orange tree is $ 6 while that of a grapefruit tree is $ 7.

Maria can paint an area of 100 square feet in one-third of an hour. At this rate, how

Answers

Answer:

A.    5 square feet per minute

Step-by-step explanation:

Answer:

The answer is 5 square feet per minute.

Step-by-step explanation:

Since 1/3 of an hour is 20 minutes, it will look like 100 square feet/20 min.

To make 20 minutes into one minute, we have to divide it by 20.

Because we did it to the denominator, we also have to do the same thing to the numerator.

Divided 100 by 20, which gives you 5.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first number be A

Now , the value of A is = 16 cm

Let the second number be = B

The value of B is = 20 cm

The ratio of A and B is calculated as C

where C = A / B

A goes to the numerator of the fraction and B to the denominator

Substituting the values in the equation , we get

C = A/B

C = 16/20

On simplifying the equation , we get

C = 4/5

Therefore , the value of C is 4 : 5

Hence , the value of equation is 4 : 5

The perimeter of a triangular shaped garden is 24 feet. The third side is one more than four times the first side. The second side is three more than the first side
What is the length of the longest side of the garden?

Answers

Answer:

14 1/3 feet

Step-by-step explanation:

let 's' = shortest side

let '4s + 1' = longest side

let '3 + s' = middle side

s + 4s + 1 + 3 + s = 24

6s + 4 = 24

6s = 20

s = 20/6 or 3 1/3

longest side: 4 · 10 + 1

                             3

= 40/3 + 1

= 13/ 1/3 + 1

= 14 1/3

The rectangle to the right has width 6x5 feet and length 9x8 feet. Find its area as
an expression of x.

Answers

Answer:

54x¹³

Step-by-step explanation:

area = L x W

where L = 9x⁸

          W = 6x⁵

plugin values into the formula:

Area = 9x⁸ * 6x⁵

        = 54x¹³

The area of the rectangle as an expression of x is [tex]2160x^3[/tex] square feet.

To find the area of the rectangle, we can use the formula for the area of a rectangle, which is:

Area = length × width

Given that the width is 6x5 feet and the length is 9x8 feet, the area of the rectangle is:

Area = (9x8) × (6x5)

To simplify the expression, multiply the coefficients and combine the variables:

[tex]Area = 54x^2 * 40x[/tex]

Now, multiply the coefficients:

[tex]Area = 2160x^3[/tex]

So, the area of the rectangle as an expression of x is [tex]2160x^3[/tex] square feet.
