Answer:

The height is 1.25m.

Step-by-step explanation:

Volume = 1/3 πr²h

Given:

V = 13.4 m³

r = 3.2 m

Asked: height (h)

Substitute the formula with the given values then solve

13.4m³ = 1/3π(3.2m)²h

13.4(3) = 10.24πh

40.2 = 10.24πh

h = 40.2/10.24π

h = 1.25m

The height of the cone is 1.25 meters.

We know that the volume of the cone is given by

V = (1 / 3) * π * r ^2 * h................equation 1

where,

V is the volume of the cone.

r is the radius of the cone's base

h is the height

The volume and radius of the cone are given,

V = 13.4 m

r = 3.2m

substituting these values in equation 1 we get,

13.4 = (1 / 3) * 3.14 * 3.2 ^ 2 * h

on simplifying further

13.4 = 10.717  * h

h = 1.25m

The height of the cone is 1.25 meters.

Answer:

The answer is 88 square inches. (A)

Step-by-step explanation:

The shape is broken up into 2 right triangle sand 2 rectangles.

The area of the triangle is 12. You subtract the way it is cut in half where the dashed line that sais (4 in.) so you take 7 - 4 = 3. Now that the 3 is left meaning it is the height  of the triangle. and then the bashed line that says

(8 in.) is the base of the triangle. Multiply that and it is 24 but you have to divide by 2 which gives you 12. since there are "Identical" triangles what I do is add 12 which will give you 24 again bc of both triangles combined.

As for the rectangle is both dashed lines (4 in. And 8 in.) multiply it gives you 32, again since here is another "Identical" rectangle you add 32 + 32 = 64 (Both rectangles combined)

Lastly add 64 + 24 = 88

I graphed it using slope-intercept form.

Answer:

Slope-intercept form: (y=mx+b) y=3x+10

To graph, place points at (-2, 4), (-3, 1), and (-4, -2), then draw a line connecting them

Step-by-step explanation:

The 10 in the equation represents where the line will intercept the y-axis. The 3x means that for every 1 unit you move to the right, you move 3 units up (or 1 to the left, 3 units down).

Step-by-step explanation: Well to begin, you take 15$ and multiply it by 4, since he wants to buy 4 of those tickets, which is 60$. Then, take the 10$ and multiply it by 2 since he wants 2 of those tickets, which is 20$, you then apply 10% to 60 and 20 by taking 10 percent of 60, then adding  it to 60 once have that, which is 66, you take the 3% and find 3% of 66, then add the answer of that to 66, which is 67.98$, you then do the same thing to the 20$.

Answer:

14.0362 degrees (round to 14.0 degrees)

Step-by-step explanation:

1. Assume that the math can be deduced by the sides of a triangle due to the "sightline" nature of the problem. This is a classic trig problem you will see.

2. The base of the triangle would be 12 feet and one of the legs of the triangle will be 3 feet.

3. Arctangent will provide the angle of elevation. The equation can be written as arctan(h/b), in this case h = height and b = base.

4. The calculation will be arctan(3/12) which translates to 14 degrees which is, fortunately, the angle of elevation.

I recommend trying this method out with another example such as the angle of elevation between you and the next plane you see in the sky. For example, the height difference between you and the plane is 7 miles and the plane is x miles away. Again we can create a simple triangle to discover many interesting details.

The area of the riders field of view is 987.5 square yards.

Step-by-step explanation:

The human has a 180° arc view. If the rider can see only 25 yards, the area of the riders field of view is a semi-circle (180° arc) of 25 yards of radius.

The semi-circle of 25 yards of radius has an area of:

\(S=\dfrac{1}{2}\pi r^2=\dfrac{1}{2}\cdot3.16\cdot (25)^2=\dfrac{1}{2}\cdot3.16\cdot625=987.5\)

The measure of the second largest angle in (6x-17) (4x-12) (2x+5) is 56°.

It should be noted that the value of the angle in a triangle is equal to 180°. Therefore, we will add the angle and add them to equate 180°

This will be:

(6x-17) + (4x-12) + (2x+5) = 180

6x - 17 + 4x - 12 + 2x + 5 = 180

12x -24 = 180

Collect like terms

12x = 180 + 24

12x = 204

Divide

x = 204 / 12

x = 17

First angle = 6x - 17 = 6(17) - 17 = 85°

Second angle = 4x - 12 = 4(17) - 12 = 68 - 12 = 56°

Third angle = 2x + 5 = 2(17) + 5 = 39°

Sasha buys 5 boxes crackers for 12.25 if each box cost the same amount  one box of crackers costs $2.45.

To find the cost of one box of crackers, we can use the concept of unit rate, which is the cost per one unit. In this case, we want to find the cost per one box of crackers.

If Sasha bought 5 boxes of crackers for a total of $12.25, we can set up a proportion to find the cost of one box of crackers:

5 boxes / $12.25 = 1 box / x

Here, "x" represents the cost of one box of crackers. We can solve for "x" by cross-multiplying the proportion:

5 boxes * x = $12.25 * 1 box

5x = $12.25

x = $12.25 / 5

x = $2.45

To check our answer, we can multiply the cost of one box by the number of boxes Sasha bought:

$2.45 * 5 boxes = $12.25

This confirms that our answer is correct.

c. 105-\(\frac{84}{84}\) = 104.0

d. 170 - \(\frac{125}{125}\) = 169.0

Answer:

Option B.

Step-by-step explanation:

Let as consider the given equation:

\(2\ln e^{\ln 2x}-\ln e^{\ln 10x}=\ln 30\)

It can be written as

\(2(\ln 2x)-(\ln 10x)=\ln 30\)         \([\because \ln e^a=a]\)

\(\ln (2x)^2-(\ln 10x)=\ln 30\)        \([\because \ln a^b=b\ln a]\)

\(\ln \dfrac{4x^2}{10x}=\ln 30\)        \([\because \ln \dfrac{a}{b}=\ln a-\ln b]\)

\(\ln \dfrac{2x}{5}=\ln 30\)

On comparing both sides, we get

\(\dfrac{2x}{5}=30\)

Multiply both sides by 5.

\(2x=150\)

Divide both sides by 2.

\(x=75\)

Therefore, the correct option is B.

Answer:

will you help me with grade 9 math, algebra 2 please

Step-by-step explanation:

Answer:

We know that the x-coordinate of point A is -11, and that the distance between point A and point B is 15 units. Let's call the y-coordinate of point A "y". Then we can use the distance formula to find the two possible values of y:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1,y1) = (-11,y) is the coordinates of point A, and (x2,y2) = (1,2) is the coordinates of point B. Substituting the values, we get:

15 = sqrt((-11 - 1)^2 + (y - 2)^2)

15 = sqrt(144 + (y - 2)^2)

15^2 = 144 + (y - 2)^2

225 = 144 + (y - 2)^2

81 = (y - 2)^2

y - 2 = ±9

y = 2 ± 9

So the possible coordinates of point A are (-11,11) and (-11,-7).
