mart [117]4 years ago

6 0

Answer:

Step-by-step explanation:

Step 1: Rearrange -3x + y = -6 into y = mx + b

y = 3x - 6

Step 2: Find the y-intercept

The y-intercept is "b" so in this case the y-intercept is -6

Step 3: Use $\frac{rise}{run}$ to graph this equation

We start at (0,3) the y-intercept and go up by 3 and left by 1 ( $\frac{rise}{run} =\frac{3}{1}$ )

Answer:

900 cubic inches.

Step-by-step explanation:

Given the following data;

Volume of right circular cone = 300in³

We know that the volume of a right circular cone is given by the formula;

$V = \frac {1}{3} \pi r^{2}h$

Where;

V is the volume of right circular cone.

r is the radius of the base of the right circular cone.

h is the height of the right circular cone.

The volume of a right circular cylinder is given by the formula;

$V = \pi r^{2}h$

Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.

$V = \frac {1}{3} \pi r^{2}h * 3$

Substituting into the equation, we have;

$V = 300 * 3$

V = 900in³

Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.

Answer:

10 2/3 in

Step-by-step explanation:

Subtract the values:

19 1/12 - 8 5/12 =
18 13/12 - 8 5/12 =
18 - 8 + 13/12 - 5/12 =
10 + 8/12 =
10 8/12 =

Find side x , give your answer 1 decimal place

Vladimir [108]

Given:

Let A denote the angle of the given triangle which measures ∠A = 81°

Let B denote the angle which measures ∠B = 40°

The length of the side a = x.

The length of the side b = 7 cm.

We need to determine the value of x.

Value of x:

The value of x can be determined using the law of sine formula.

Applying the law of sine, we have;

$\frac{sin \ A}{a}=\frac{sin \ B}{b}$

Substituting the values, we have;

$\frac{sin \ 81^{\circ}}{x}=\frac{sin \ 40^{\circ}}{7}$

Simplifying, we get;

$\frac{0.988}{x}=\frac{0.643}{7}$

Cross multiplying, we have;

$0.988 \times 7=0.643 x$

$6.916=0.643x$

$10.8=x$

Thus, the length of the side x is 10.8 cm.
