Answer:

length of side BC = 11.9cm

The complete question found on brainly (ID: 14303570 ) is stated below:

Find the length of side BC.

Give your answer to 1 decimal place.

∠A = 58°

AC = 14cm

Find attached the diagram of the triangle.

Step-by-step explanation:

From the diagram

∠A = 58°

∠B = 90°

AC = 14cm

The triangle is a right angled triangle

To get the length side of BC, we would

apply trigonometry SOHCAHTOA.

In this question the sine ratio would be appropriate since we know the hypotenuse but we are looking for the opposite side (BC).

Sine ratio: Sin58° = opposite/hypotenuse

Sin58° = BC/AC

Sin58° = BC/14

BC = 14sin58°

BC = 14 × 0.8480

BC = 11.9cm

length of side BC = 11.9cm (1 decimal place)

If the average of nine consecutive integers is zero, what is the largest integer?

Orlov [11]

Answer:

Step-by-step explanation:

The average of the consecutive integers is 0, so the middle number must be 0, with 4 numbers less than 0 and 4 numbers greater than 0.

-4, -3, -2, -1, 0, 1, 2, 3, 4

So the largest integer is 4.

The Greenpoint factory produced two-fifths of the Consolidated Brick Company’s bricks in 1991. If the Greenpoint factory produce

ohaa [14]

Answer:

3500 tons

Step-by-step explanation:

The Greenpoint factory produced 2/5 of the bricks that the Consolidate Brick Company produced in 1991.

Let the amount of bricks produced by the Greenpoint factory be g and the amount of bricks produced by the Consolidated brick company be c.

Therefore:

g = 2/5 * c = 2c/5

That year, the Greenpoint factory produced 1400 tons of bricks. This implies that:

1400 = 2c/5

To find the amount that the Consolidated Brick Company produced, solve for c:

1400 = 2c/5

1400 * 5 = 2c

7000 = 2c

c = 7000 / 2 = 3500 tons

The Consolidated Brick Company had a total production output of 3500 tons in 1991.

Solve the system using elimination.

Molodets [167]

Answer:

(-1, 3)

Step-by-step explanation:

x - 5y = -16 [Equation 1]

-x + 3y = 10 [Equation 2]

<u>Adding both equations</u>

x - x - 5y + 3y = -16 + 10
-2y = -6
y = 3

x - 5(3) = -16
x - 15 = -16
x = -1

<u>Solution</u> : (-1, 3)
