Answer 1

Answer:

60 degrees

Step-by-step explanation:

This is a complementary angle, so the equation to use is 30+x=90.

To find out what x is, we have to use the Subtraction Property of Equality.

30+x=90

-30 -30

x=60

The area of a rectangular field is 99m2. The length of one side is
11m. The farmer needs to know its perimeter to work out how
much fencing will be needed? Help

Answers

Answer:

40 m

Step-by-step explanation:

The length of another side

= 99÷11

= 9 m

The perimeter of the field

= 9×2 + 11×2

= 40 m

Answer:

40 m

Step-by-step explanation:

Hi there!

What we know:

The field is rectangularA = 99 m²Length of one side = 11 m

1) Find the length of the other side

Plug all the given information into the area formula for a rectangle:

[tex]A=lw[/tex] where A is the area, l is the length and w is the width

[tex]99=11w[/tex]

Divide both sides by 11 to isolate w

[tex]\frac{99}{11} = \frac{11w}{11} \\9=w[/tex]

Therefore, the width of the field is 9 m.

2) Find the perimeter of the field

[tex]P=2(l+w)[/tex] where l is the length and w is the width

Plug in the length (11 m) and the width (9 m)

[tex]P=2(11+9)\\P=2(20)\\P=40[/tex]

Therefore, the perimeter of the field is 40 m.

working backwards. answer all questions numbers 14-16

Answers

14. height = volume/ ( length x width)

Height = 224/ ( 2x8)

Height = 224/16

Height = 14 inches.

15. height = volume/ area of the top(circle)

Area of top = pix r^2 = 3.14 x 4 = 12.56 square inches.

Height = 62.8/12.56 = 5 inches

16. Volume/ height = area of top(circle)

169.56/ 6 = 28.26 square inches

Area = pi x r^2

28.26 = 3.14 x r^2

Divide both sides by 3.14

R^2 = 28.26/3.14 = 9

Take the square root of both sides

R = sqrt(9)

R = 3

Radius = 3 inches

The area of the large rectangle is twice the area of the small rectangle. What is the value of x?Two rectangles are shown. The larger rectangle has dimensions 4 centimeters by 12 centimeters. The smaller rectangle has dimensions 3 centimeters by x centimeters. A. 7 cm B. 8 cm C. 11 cm D. 13 cm

Answers

Answer:

B. 8 cm.

Step-by-step explanation:

The area of a rectangle is the length*width.

The area of the larger rectangle is 4*12=48.

The area of the smaller rectangle is 3*x=3x.

If the larger rectangle's area is twice that of the smaller rectangle, then we can say 48=2*3x.

Let's solve for x

48=2*3x

48=6x

x=8
