The area of the rectangular garden is determined as 192 ft² from the product of the width and length.

The area of the rectangular garden is calculated by applying the following method.

let the width of the garden = w

then, length of the garden = 3w

The resultant length or remaining length;

= 3w - w

= 2w

The value of the width of the garden is calculated by applying the formula for perimeter of a rectangle.

2w + w + 2w = 40

5w = 40

w = 40/5

w = 8 ft

So the length of the garden = 3 x 8 = 24 ft

The area of a rectangle is calculated as follows;

Area = 8ft x 24 ft

Area = 192 ft²

Answer:

hyperbola is formed by intersecting two inverted cones and a plane.

Answer:

parallelogram

Step-by-step explanation:

slope of DE = (4-7) / (-4 - 2) = 1/2

slope of FT = (-3 - -6) / (11-5) = 1/2

DE // FT

slope of EF = (-6 - 4) / (5 - -4) = - 10/9

slope of DT = (-3 - 7) / (11 - 2) = - 10/9

EF // DT

The quadrilateral is formed by the vertices  D(2, 7), E(-4, 4), F(5, -6), and T(11, -3) will be a parallelogram.

A parallelogram is a quadrilateral having four sides and the two opposite sides are equal and parallel to each other.

Given that quadrilateral, DEFT has vertices D(2, 7), E(-4, 4), F(5, -6), and T(11, -3).

Slope of DE = (4-7) / (-4 - 2) = 1/2

Slope of FT = (-3 - -6) / (11-5) = 1/2

DE is parallel to  FT.

Slope of EF = (-6 - 4) / (5 - -4) = - 10/9

Slope of DT = (-3 - 7) / (11 - 2) = - 10/9

EF is parallel to DT.

Therefore, the quadrilateral is formed by the vertices  D(2, 7), E(-4, 4), F(5, -6), and T(11, -3) will be a parallelogram.

i think its not equivalent but NOT sure

Step-by-step explanation:

Answer:

90 min

Step-by-step explanation:

if 2 miles is equal to36 minutes what about 5 miles

Answer:

90 minutes. 1 hour, 30 minutes.

Step-by-step explanation:

36 minutes = 2 miles

? minutes = 5 miles

There are many ways to solve this, for example, creating an equation. But I am going to show you how to solve this using fractions.

Step 1: Set up a fraction.

Make sure your values are in the correct order. 2 miles is 36, so 5 miles would be a variable. We will make that variable of time "t".

[tex]\frac{36}{2} = \frac{t}{5}[/tex]

Also, make sure the values with the same units are on the same level. For example, 2 miles and 5 miles are both under, although they can be at the top, too, they just both have to be at the same place.

Step 2: Solve for the variable.

[tex]\frac{36}{2} = \frac{t}{5}[/tex]

On one side, we see 36 over 2. We should solve that first. [tex]\frac{36}{2}=36\div2=18[/tex]

We are left with [tex]18 = \frac{t}{5}[/tex]

Multiply 5 to both sides

[tex]5\cdot18=\frac{t}{5} \cdot5[/tex]

18 times 5 equals 90

5 cancels 5, so that leaves us with 90.

Step 3: Convert 90 minutes to hour.

60 minutes = 1 hour

Since we know 60 minutes makes 1 hour, we can find out how many are left from 90 minutes by subtracting 60 from 90

[tex]90-60=30[/tex]

It will take 1 hour and 30 minutes to walk 5 miles.

1. 56.4

2.107.15

So for the first one I subtracted like this:53.41- -2.99=56.4

You may be wandering why i subtracted that way,I did that because you are meant to subtract and the second number already has a negative sign which is MINUS.

And for the second I subtracted the smaller number from the bigger number this way:144.96 ‐ 37.8

Is your answer.

Step-by-step explanation:

integers and exponents

In this problem, we build and solve an expression.

a)

The expression is:

[tex]350 + 10s = 1250[/tex]

b) 90 students can attend the field trip.

Item a:

The spendings are:

Thus, in total:

[tex]350 + 10s[/tex]

Has $1,250.00 to spend, thus:

[tex]350 + 10s = 1250[/tex]

Item b:

The number of students that can attend the trip is the solution for s, thus:

[tex]350 + 10s = 1250[/tex]

[tex]10s = 900[/tex]

[tex]s = \frac{900}{10}[/tex]

[tex]s = 90[/tex]

Then, 90 students can attend the field trip.

Recall that

cos(x + y) = cos(x) cos(y) - sin(x) sin(y)

cos(x - y) = cos(x) cos(y) + sin(x) sin(y)

If you subtract the first equation from the second one, you end up with

cos(x - y) - cos(x + y) = 2 sin(x) sin(y)

so that

sin(3x) sin(x) = 1/2 (cos(3x - x) - cos(3x + x)) = 1/2 (cos(2x) - cos(4x))

Then in the integral,

[tex]\displaystyle \int \sin(3x)\sin(x)\,\mathrm dx = \frac12 \int(\cos(2x)-\cos(4x))\,\mathrm dx \\\\ = \frac12 \left(\frac12 \sin(2x) - \frac14 \sin(4x)\right) + C \\\\ = \boxed{\frac14 \sin(2x) - \frac18 \sin(4x) + C}[/tex]

33,1 + (-8,7)

= 24,4

Answer:

Step-by-step explanation:

Given points (-2, 1) and (6, -1):

Start by solving for the slope of the line, using the following formula:

m = (y2 - y1)/(x2 - x1)

Let (x1, y1) =  (-2, 1)

(x2, y2) =  (6, -1)

m = (y2 - y1)/(x2 - x1)

m = (-1 - 1)/[6 - (-2)]

m = -2/(6 + 2) = -2/8 = -¼

Therefore, the slope of the line is m = - ¼.

Next, to determine the y-intercept (b), use one of the given points (6, -1) and the slope, and plug in these values into the slope-intercept form:

y = mx + b

-1 =  -¼(6) + b

-1 = -3/2 + b

-1 + 3/2 = -3/2 + 3/2 + b

½ = b

Therefore, the y-intercept, b = ½.
