Step-by-step explanation:

Given:

Area of square land = 3,600 m²

Find:

Perimeter of his fence

Computation:

Area of square land = 3,600 m²

4a² = 3,600 m²

a² = 900 m²

a = 30 m

Perimeter of his fence = 4a

Perimeter of his fence = 4 x 30

Perimeter of his fence = 120 m

Step-by-step explanation:

Answer:

Both ate 52 degrees

Step-by-step explanation:

You can find the measure of angle 5 by subtracting 128 from 180, which equals 52. From there you can deduct that angles 3 and 1 are congruent to 5, making them both 52 degrees.

Answer:

Step-by-step explanation:

if you know 50*4=200, you must also know that 50*10=500 and that 4*100=400 so 500*400= 50*10*4*100

multiplication is comutative so

50*4*10*100=200*1,000= 200, 000

Answer:

500×400=

5×4=20

=20+(4 of zero)0000

3.19 become 3.20 . 1.69 becomes 1.70. Then 3.20 plus 1.70 is 4.90 or 4.9.

Answer:

D. 4.9

3.19 -> 3.2

1.69 -> 1.7

3.2 + 1.7 = 4.9

Step-by-step explanation:

since it's 20% off, that means it's sold at 80%.

Answer:

A"(-1, -3), B"(-2, -6), C"(1,-7)

Step-by-step explanation:

y= -4 is a horizontal line that cuts y-axis at (0, -4)

A'(-4, -5), B'(-5,-2), C'(-2,-1) are given on thhe graph

first we reflect over the line m, y= -4

A"(-4, -3), B"(-5, -6), C"(-2,-7) because the line m is the bisector of what conects the image and preimage points

second we translate T(3,0) so you add a 3 to the x coordinate of each point

A"(-4+3, -3), B"(-5+3, -6), C"(-2+3,-7)

A"(-1, -3), B"(-2, -6), C"(1,-7)

The ratio of cups of flour to tablespoons of peanut butter if Felipe makes 3 batches of dog treats is, 1/4

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Given that,

Felipe makes 3 batches of dog treats

The recipe for peanut butter dog treats,

(Ingredient)                 (amount)

Peanut butter              4 tbsp

Flour                             1 cup

Egg                               1

Water                           2 tbsp

For 3 batches

Peanut butter required = 3 × required for one batch

                                       = 3 × 4

                                       =  12 tbsp

Flour Required               =  3 × required for one batch

                                       =  3 × 1

                                       =  3

the ratio of cups of flour to tablespoons of peanut butter =  3/12

                                                                                                =  1/4

Hence, the ratio is 1/4

Answer:

2.2 m

Step-by-step explanation:

Assuming that spoke refers to the radius (r) of the wheel, you can determine the circumference of the wheel using 2(pi)(r).

2 x (22/7) x 35cm

= 220cm

As this answer is in cm, it needs to be converted to m to be a correct answer. As 1m = 100cm, 220cm x 0.01 = 2.2m

Answer:

x =32

Step-by-step explanation:

create equation

180 = 3x + 20 + 2x

combine like terms

180= 3x + 20 + 2x

180=5x + 20

subtract 20 from both sides of the equation

180=5x + 20

180-20= 5x +20 -20

simplify

160= 5x

divided both sides by 5

160/5=5x/5

solution

32= x

Answer:

A decagon has 10 sides so its interior angles add up to 180(10) - 360 = 1440 degrees. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees.

Step-by-step explanation:

The total sum of the interior angles of a simple decagon is 1440°

Answer:

represent a Pythagorean triple consists of three positive integers a, b, and c, such that a^2 plus b^2 = c^2

By definition of tangent,

tan(x) = sin(x) / cos(x)

so if tan(x) < 0, and we're given cos(x) = -1/4 < 0, then it follows that sin(x) > 0.

Recall the Pythagorean identity:

cos²(x) + sin²(x) = 1   →   sin(x) = + √(1 - cos²(x))

Then

sin(x) = √(1 - (-1/4)²) = √(15/16) = √(15)/4

Recall the double angle identity:

sin(2x) = 2 sin(x) cos(x)

Then

sin(2x) = 2 • √(15)/4 • (-1/4) = -2√(15)/16 = -√(15)/8
