arc ABC = 4π $\frac{134}{180}$

Step-by-step explanation:

Given,

∠BOA = 51° and ∠AOC=83°

We take O as the center

So, ∠BOC = 51°+83° = 134°

To find the arc ABC

Formula,

The relation between arc and radius is, s = rθ where s be the arc and θ be the angle measured in radian]

θ degree = θΠ× $\frac{1}{180}$ in radian

Hence,

arc ABC = 4π $\frac{134}{180}$

each term of a sequence is 2 more than the previous term if the third term is eight, what are the first five terms of the sequen

Pavel [41]

If the third term is 8, and it is 2 greater than the previous term, the second term must be 6 and the first term must be 4. To find the fourth and fifth term, add 2 to 8 to get 10, then add 2 to 10 to get 12. The first five terms in the sequence are 4, 6, 8, 10, 12.

The total length of the fence around a quadrilateral-shaped garden shown is 3 a 2+ 15a + 9. What expression represents the missi

anyanavicka [17]

Answer:

the missing fence length = 2a² + 18

Step-by-step explanation:

3a²+15a+9 = (a²-7) + (10a-2) + 5a + ? = a² + 15a -9

? = (3a²+15a+9) - (a² + 15a -9) = 2a² + 18

The recipe for cereal squares uses the ratio 20 large marshmallows to 3 cups of cereal. The ratio of mini-marshmallows to large

Nadya [2.5K]

The relationships are:

20 large marshmallows = 3 cups cereal

3 mini marshmallows = 1 large marshmallow

Therefore if there are 6 cups cereal, so we also get 40 large marshmallows. Since for every 1 large, we need 3 mini, hence:

mini marshmallows = 40 * 3 = 120

In 1925, Zbigniew Morón published a rectangle that could be dissected into nine different sized squares as shown in the diagram.

Vlada [557]

Answer:

Area of the rectangle = 1056 square units

Step-by-step explanation:

Rectangle published could be dissected into nine different squares with different sizes.

Area of the squares with different measure of sides will be,

For side length = 1 unit

Area of the square = (Side)²

= 1²

= 1 square units

For side length = 4 units

Area of the square = 4² = 16 units²

For side length = 7 units

Area of the square = 7² = 49 units²

For side length = 8 units

Area of the square = 8² = 64 units²

For side length = 9 units

Area of the square = 9² = 81 square units

For side length = 10 units

Area of the square = 10² = 100 square units

For side length = 14 units

Area of the square = 14² = 196 square units

For side length = 15 units

Area of the square = 15² = 225 square units

For side length = 18 units

Area of the square = 18² = 324 square units

Total area of the rectangle by adding these 9 squares

= 1 + 16 + 49 + 64 + 81 + 100 + 196 + 225 + 324

= 1056 square units
