The area of the garden is increased by 20 % . If the width remains the same, then the new length of the garden is 2.4 yards.

The area of Rectangle is length times of width.

Given that A decorative fence surrounds a rectangular flower garden that is 2 yards long and 3 yards wide

Area = Length × Width

Area=6 yards.

The area of the garden is increased by 20 % .

20/100=0.2

the area would equal 6 (l x w) and 6 increased by 20% equals 7.2.

As the width remains same

so we use 7.2/3 to find the new length

7.2/3=2.4 yards.

Hence, 2.4 yards is the new length of the garden.

Step-by-step explanation:

Answer:

A. -34

Step-by-step explanation:

Answer:

B, C, D and E are correct options

Step-by-step explanation:

Here, we want to get the correct options;

a. We simply divide the next term by the previous term so that we get the common ratio

That would be 16/-8 = -32/16 = -2

As we can see, the common ratio is -2 which means that the option cannot be correct

b. The 5th term is mathematically;

ar^4 = -8 * (-2)^4 = -8 * 16 = -128

This is correct

c. The 7th term is

ar^6 = -8 * (-2)^6 = -512

5th term is ar^4 = -8 * (-2)^4 = -128

So -512/-128 = 4

As we can see, this option is correct

d. 8th term is 1024

8th term is ar^7

= -8 * (-2)^7 = 1024 which is correct

e. 10th term is ar^9 = -8 * (-2)^9 = 4096

9th term is ar^8 = -8 * (-2)^8 = -2048

This is correct

Answer:

The equation of the line that is perpendicular to y = -x – 10 and contains point (-12, 1)

[tex]y=x+13[/tex]

Please note there is something wrong with the  values given question. This is correct answer.

Step-by-step explanation:

Slope of line y = -x – 10 is m1=-1

Since slope of perpendicular lines are negative reciprocal of each other

Slope of other line is m2=1

Equation of line contains point (-12, 1) and having slope m2=1 is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-1 = 1(x+12)[/tex]

[tex]y =x+12+1 \\y = x + 13[/tex]

Answer:

72°

Step-by-step explanation:

So the three angles of a triangle always add up to 180°. This means that

[tex]15x + 21x + 24x = 180[/tex]

This becomes:

[tex]60x = 180[/tex]

And solves as:

[tex]x = 3[/tex]

The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.

[tex]24x = 24(3) = 72[/tex]

The measure of the largest angle in the triangle is 72°.

72 degrees is the biggest angle in the given triangle.

The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

Given that the three angles of the triangle are 24x, 21x, and 15x

Since the sum of all the angles of the triangle is always 180 degrees

Thus,

24x +21x + 15x = 180

60x = 180

x = 3

Thus, the biggest angle would be 24x

biggest angle of triangle = 24 * 3 = 72

Therefore, the biggest angle of the given triangle is 72 degrees

Answer:

BX

Step-by-step explanation:

D = RT is an extremely important and useful formula. This formula relates distance, to rate, and time.

In this question, we are asked to find the DISTANCE travelled in the biking portion of the triathlon. Looking back to the formula, we see that the distance is equal to the rate multiplied by the time.

The rate biking is also called the average speed, which is represented by an X in this problem.

The time biking is represented by a B in this problem.

Thus, we obtain our final answer, B times X, or simply written as BX.
