The width of the rectangle can be represented by the expression (121-x^2) / (11-x).

To find the width of the rectangle, we need to divide the area of the rectangle by its length. The area of the rectangle is given by the expression 121-x^2, and the length is given by 11-x. So, we can represent the width as:

Width = (Area / Length) = (121-x^2) / (11-x)

Answer:

1 1/3

Step-by-step explanation:

I had to take the test as well Good luck!

The division is 1 1/3.

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator.

Given:

8/9 divided by 2/3

Now, we have to perform the division

= 8/9 ÷ 2/3

= 8/9 * 3/2

= 24 / 18

= 12/9

=4/3

=1 1/3

Hence, the value of the division is 1 1/3.

Final answer:

To calculate the charge for a 36-mile drive by Sigi's taxi company, multiply 0.60 by 36 to find the mileage cost, add the $4.50 bridge toll, which results in a total cost of $26.10. Hence, the correct answer is (b) $26.10.

Explanation:

The question asks how much Sigi’s taxi company will charge for a 36-mile drive considering their rate is $0.60 per mile and there is an additional charge of $4.50 for bridge tolls. To calculate the total cost, you can use the given expression 0.60m + 4.50, where 'm' represents the number of miles.

By substituting 36 for 'm', you get the following calculation: 0.60 × 36 + 4.50. The cost per mile for 36 miles amounts to $21.60 ($0.60 times 36). Add the additional $4.50 charge for bridge tolls to get a total charge of $26.10.

Step-by-Step Calculation:

Therefore, the correct option is (b) $26.10.

Answer:

up 8 on the y axis

Step-by-step explanation:

Answer:

K = 676

Step-by-step explanation:

When y is directly proportional to x and inversely poportional to z

We have

y = kx/z

When y =520

x = 5

z = 6.5

K =?

We have

520 = k x 5/6.5

Cross multiply

520 x 6.5 = 5k

3380 = 5k

Divide both sides by 5

3380/5 = 5k/5

676 = k

k = 676

Solution:

Complementary angles add up to 90° and supplementary angles add up to 180°

Let "a" be the required angle

Supplement of an angle = 180 - a

Complement of angle = 90 - a

The supplement of an angle is six times as large as the complement of the angle.

Therefore,

180 - a = 6(90 - a)

Simplify the above

180 - a = 540 - 6a

6a - a = 540 - 180

Combine the like terms

5a = 360

Divide both sides by 5

a = 72

Thus the measure of the angle to the nearest whole degree is 72 degrees

Let a, b, and c be the length of 3 corresponding sides of the triangle. The following inequality must always be true since they form a triangle :

[tex]a+b>c[/tex]

(This inequality says that the sum of two sides must always be greater than the other side)

Let's use this inequality for x, 1.3, and 4.1

[tex]x+1.3>4.1[/tex]

(The reason why 1.3 is on the left side is because it is the smaller side)

Subtract both sides by 1.3

[tex]x>2.8[/tex]

x must always be greater than 2.8. Now, let's see what value x must be always less than.

[tex]1.3+4.1>x[/tex]

[tex]5.4>x[/tex]

x must be always less than 5.4. Let's combine both statements for x and we get:

[tex]2.8<x<5.4[/tex]

These are the only values of x that will make it possible for these sides to form a proper triangle.

Step-by-step explanation:

We are asked to find the value of A. We know from the question that we need to have the sum of -3x and (A)x equal the third term of the original polynomial, which is 2x. written out in an equation, it looks like this.

[tex]-3x+(A)x=2x[/tex]

We can simplify the equation if we add 3x to both sides, which then leaves us with this.

[tex](A)x=5x[/tex]

We can further simplify the equation by dividing both sides by x. This leaves us with our last equation for this problem.

[tex]A=5[/tex]

Finally, we have our answer. We can also verify that this is a valid integer by multiplying our, now completed, quotient by the divisor and adding the remainder, which in this case, our remainder is 0, so we will not be including it in our operation.

If our calculations were all correct, the product of these polynomials should equal our dividend, verifying our integer is valid; lo' and behold, it is.

Answer:

The total area of the field is 7378.8 square meters.

The total area of the field is 8825.0448 square yards.

Step-by-step explanation:

Given : A soccer field (football pitch) has a length of 103.2 m and a width of 71.5 m.

To find : The total area of the field in square meters (m²) and convert this measurement to square yards (yd²) ?

Solution :

The length l=103.2 m

The width w=71.5 m

The area of the field is [tex]A=l\times w[/tex]

[tex]A=103.2\times 71.5[/tex]

[tex]A=7378.8\ m^2[/tex]

The total area of the field is 7378.8 square meters.

We know that,

1 m²= 1.196 yd²

[tex]7378.8\ m^2=7378.8\times 1.196\ yd^2[/tex]

[tex]7378.8\ m^2=8825.0448\ yd^2[/tex]

The total area of the field is 8825.0448 square yards.

The area of the soccer field is 7378.8 m^2 and 8822.6 square yards.

The area of a rectangle (which is the shape of a soccer field) can be found by multiplying the length and the width. So, the area of the soccer field in square meters is 103.2 m (length) times 71.5 m (width), which equals 7378.8 m2.

To convert this area to square yards, you should know that 1 square meter is approximately equal to 1.19599 square yards. So, multiply our previous answer with this value. The area of the soccer field will be 7378.8 m2 times 1.19599 to get 8822.6 yd2.

Answer:

Approximately 252 inches squared.

Step-by-step explanation:

Answer:

126 in.^2

Step-by-step explanation:

The hexagon is divided into 6 congruent triangles. The area of the hexagon is 6 times the area of one of the triangles.

Now think of each triangle.

The side of the hexagon is the base of the triangle. The side of the hexagon has length 7 inches, so the base of the triangle has length 7 inches.

The height of the triangle is approximately 6 inches.

area of triangle = base * height/2

area of hexagon = 6 * area of triangle

area of hexagon = 6 * base * height/2

area of hexagon = 3 * base * height

area of hexagon = 3 * 7 in. * 6 in.

area of hexagon = 126 in.^2

Answer:

Step-by-step explanation:

[tex]3x+5=20\qquad\text{subtract 5 from both sides}\\\\3x+5-5=20-5\\\\3x=15\qquad\text{divide both sides by 3}\\\\\dfrac{3x}{3}=\dfrac{15}{3}\\\\x=5[/tex]

Answer:

x = 5.

Step-by-step explanation:

3x +5 = 20

Subtract 5 from both sides:

3x + 5 - 5 = 20 - 5

3x = 15

Divide both sides by 3:

x = 15/3

x = 5.

The surface area of the present in the shape of a cube is 2,400 square centimeters.

The present takes the shape of a cube.

The formula for the surface area of a cube is expressed as:

Surface area = 6( a² )

Where a is the edge length.

From the figure, the edge length of the present is;

Edge length a = 20cm

Surface area =?

To determine the surface area of the present, plug the given value into the above formula:

Surface area = 6( a² )

Surface area = 6( 20² )

Surface area = 6( 400 )

Surface area = 2,400 cm²

Therefore, the surface area measures 2,400 cm².

y = 75

Solution:

In a straight line, sum of the adjacent angles = 180°

80° + m∠DGF = 180°

Subtract 80° from both sides of the equation.

m∠DGF = 100°

Sum of all the interior angles in a quadrilateral = 360°

m∠DGF + m∠GFE + m∠FED + m∠EDG = 360°

100° + 120° + 65° + y° = 360°

285° + y° = 360°

Subtract 285° from both sides, we get

y° = 75°

Hence the value of y is 75.
