The length of the tile Candace is designing is 3 /2 meters.

The rectangular tiles he is designing has the following dimension:

width = 3/5 meters

area = 9/10 meters

The length of the tiles Candace is designing can be calculated below:

area of a rectangle = lw

where

l = length

w  = width

Therefore,

9/10 = 3/5 l

cross multiply

9 × 5 = 3 × 10l

45 = 30l

divide both sides by 30

45 / 30 = l

l = 9 / 6 = 3 / 2 meters

length = 3 / 2 meters

What are the dimensions of the garden with the largest area she can enclose?

The dimensions of the garden with the largest area she can enclose are length for cedar side = 7 foot and width for other side =  10 foot

Let L = length of the fence and W = width of the fence.

Also, let L be the length of cedar fencing.

Since we require one side of cedar fencing and the other 3 sides of cheaper metal fencing, and the cedar fencing costs $13/foot and the cheaper material costs $7/foot, the total cost of fencing is C = 13L + 7L + 2W × 7

= 13L + 7L + 14W

= 20L + 14W.

Since the total amount my friend wants to spend on fencing is $280, C = 280.

So, 20L + 14W = 280

10L + 7W = 140 (1)

Also, the area of the rectangular area is A = LW

From (1), L = (140 - 7W)/10

Substituting L into A, we have

A = LW

A = (140 - 7W)W/10

A = 14W - 0.7W²

To find the value of W that makes A maximum, we differentiate A with respect to W.

So, dA/dW = d(14W - 0.7W²)/dt

dA/dW = 14 - 1.4W

Equating it to zero, we have

14 - 1.4W = 0

14 = 1.4W

W = 14/1.4

W = 10 feet

To determine if this value maximizes A, we differentiate dA/dW with respect to W.

So, d²A/dW² = d(14 - 1.4W)/dW = -1.4

Since d²A/dW² = -1.4 < 0, W = 10 feet is a maximum point.

Since L = (140 - 7W)/10,

substituting W = 10 into the equation, we have

L = (140 - 7W)/10

L = (140 - 7 × 10)/10

L = (140 - 70)/10

L = 70/10

L = 7 feet

So, the dimensions of the garden with the largest area she can enclose are length for cedar side = 7 foot and width for other side =  10 foot

What is the largest area that can be enclosed?

The largest area that can be enclosed is area = 70 foot-squared

Since the area A = LW

Substituting the values of L and W into the e quation, we have

A = LW

A = 7 × 10

A = 70 ft²

So, the largest area that can be enclosed is area = 70 foot-squared

Answer:

2 3/4

Step-by-step explanation:

x = 1/4

y = 1/2

so we have to plug in these numbers wherever we see x and y

2 (1/16 + (1/4)^2) + 5(1/2)

using pemdas we solve what's in the parenthesis first

(1/16 + (1/4)^2) = (1/8)

next is multiplication so

2 (1/8) = 1/4 and 5(1/2) = 5/2

lastly we add so

1/4 + 5/2 = 11/4 or 2 3/4

Answer:

226

Step-by-step explanation:

In the given picture,

Trapezoid PQRS has two points T and U as the midpoints of sides PS and RQ.

Segment TU joins the midpoints of the sides PS and RQ.

Mid-segment theorem states that "If a line joining midpoints of a trapezoid is parallel to the bases, length of this segment is half the sum of lengths of the bases."

Therefore, m(TU) =

7x - 26 =

7x - 26 = 6x + 10

7x - 6x = 26 + 10

x = 36

m(TU) = 7x - 26

         = 7(36) - 26

         = 252 - 26

         = 226

Therefore, Option (1) will be the answer.

Answer:

a diagram? or just how to solve it

Step-by-step explanation:

We want to see how much must vary x so the argument of f(x) varies by 2 pi. We will see that x must vary (2π)/0.65.

So let's take the variation from 0 to 2π.

The argument is zero when x = 0

Argument = 0.65*x

if x = 0

Argument = 0.65*0 = 0

Now let's see which must be the value of x such that the argument is equal to 2π, so we must solve:

2π = 0.65*x

(2π)/0.65 = x

So we can see that x must vary from 0 to (2π)/0.65, or just a variation of (2π)/0.65.
