Answer:

Step-by-step explanation:

So we need to find the exact volume of the cone, so we will use the formula pi r^2 h/3 to solve. Pi x 1.5^2 x 4.5/3 = V. The volume of your cone is about 10.6.

Answer:

B. 10.6 cubic inches.

Step-by-step explanation:

The formula for a volume of the cone is V = 1/3 π r² h,

where:

V - the volume of the cone,

r - radius of the cone base,

h - height of the cone.

It is given:

h = 4.5 in

r = 1.5 in.

π = 3.14

If:

V = 1/3 π r² h,

Then:

V = 1/3 × 3.14 × (1.5 in)² × 4.5 in

V = 1/3 × 3.14 × 2.25 × 4.5 in³

V = 10.6 in³

Therefore, Judy's sugar cone can hold 10.6 in³.

Liula [17]

Answer:

24.59 feet

Step-by-step explanation:

Let x represent the distance between Sam and the bird.

We have been given that am the owl is looking down at a 24° angle from the top of a tree that is 10 ft tall, when he spots a bird on the ground. We are asked to find the distance between Sam and the bird.

We can see from our attachment that Sam, the bird and angle of depression forms a right triangle with respect to ground. We can see that side 10 ft is opposite side and and side x is hypotenuse for the 24 degree angle.

$\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}$

$\text{sin}(24^{\circ})=\frac{10}{x}$

$x=\frac{10}{\text{sin}(24^{\circ})}$

$x=\frac{10}{0.406736643076}$

$x=24.5859333557$

$x\approx 24.59$

Therefore, the bird is approximately 24.59 feet away from Sam.

zimovet [89]

Answer:

Step-by-step explanation:

y = -2x+5

slope of line is -2.

slope of parallel to line is also -2

point-slope equation for line of slope -2 that passes through (-5,3):

y-3 = -2(x+5)

Solve by factoring:<br> 1) x² + 6x + 8 = 0

Serhud [2]

Answer:

x=-4 x=-2

Step-by-step explanation:

x² + 6x + 8 = 0

x² +2x+4x + 8 = 0

x(x+2)+4(x+2)=0

(x+4)(x+2)

x=-4 x=-2

leva [86]

Firstly, you have to count the number of spaces between the two points on the line, which gives you 9. Now, remember that you are counting between tenths on a number line, so you divide 9 by 10 to give you your answer, 0.9.
