The height of the triangle is 22 centimeters. When The area of a triangular flag is 330 square centimeters

To find the height of the triangle, we can use the formula for the area of a triangle, which is given by:

Area = (1/2) * base * height

where "base" is the length of the base of the triangle, and "height" is the height of the triangle.

Given that the area of the triangular flag is 330 square centimeters and the base is 30 centimeters, we can plug these values into the formula and solve for the height:

330 = (1/2) * 30 * height

To find the height, first, multiply 30 by (1/2):

330 = 15 * height

Now, divide both sides of the equation by 15 to solve for the height:

height = 330 / 15

height = 22

So, the height of the triangle is 22 centimeters.

Answer:

The total area of the prism is [tex]SA=(\frac{9\sqrt{3}}{2}+54)\ in^{2}[/tex]

Step-by-step explanation:

we know that

The surface area of the triangular prism of the figure is equal to

[tex]SA=2B+PL[/tex]

where

B is the area of the triangular face

P is the perimeter of the triangular face

L is the length of the prism

Find the area of the base B

The base is an equilateral triangle

so

Applying the law of sines the area is equal to

[tex]B=\frac{1}{2}(3)^{2}sin(60\°)[/tex]

[tex]B=\frac{9\sqrt{3}}{4}\ in^{2}[/tex]

Find the perimeter P of the triangular face

[tex]P=(3+3+3)=9\ in[/tex]

we have

[tex]L=6\ in[/tex]

Check the picture below.

make sure your calculator is in Degree mode.

Answer:

37.0

Step-by-step explanation:

You have a total of 3 triangles in one here.  Triangle ABC, triangle ABD, and triangle DBC.  If we can find out the length of side BD in triangle DBC that will help us later.  We have angle D and side DC and we are looking for the hypotenuse of that right triangle DBC.  The trig ratio that relates the side adjacent to the reference angle to the hypotenuse is the cosine:

[tex]cos(40)=\frac{20}{BD}[/tex]

Solving for BD:

[tex]BD=\frac{20}{cos(40)}[/tex]

That gives us that BD = 26.1

Now that we know that, we can move into the obtuse triangle that shares the side BD with the right triangle.  We have that angle BDC is 40 degrees, and since angle ADB is supplementary to angle BDC, then angle ADB measures 180 - 40 = 140.  So angle A is 30, angle ADB is 140, so that means that angle ABD is 10.  Because triangle ABD is obtuse and not right you cannot use Pythagorean's Theorem.  But you can use the Law of Sines.  Set it up like this:

[tex]\frac{sin(140)}{AB}=\frac{sin(10)}{10}[/tex]

Solve for side AB:

[tex]AB=\frac{10sin(140)}{sin(10)}[/tex]

In degree mode on your calculator you'll find that side AB is 37.0

Answer:

The trains will meet after 2.6 hours.

Step-by-step explanation:

Add up the distances traveled by the two trains:

distance1 = (100 mph)(t hours)

distance2 = (90 mph)(t hours)

Sum of distance1 and distance2 = 494 miles = (190 mph)(t hours)

Solving for t, we get   t = 494 miles / 190 mph  = 2.6 hours

The trains will meet after 2.6 hours.

It will take 2.60 hours for the two trains to meet.

To find out how long it will take for the two trains to meet, we can use the formula: time = distance / speed.

Since the trains are traveling towards each other, we can add their speeds together to get the effective speed: 100 mph + 90 mph = 190 mph.

Now we can plug in the values: time = 494 miles / 190 mph = 2.60 hours.

The third equation down is the one you want

Step-by-step explanation:

What you need for this is the point-slope form of a line:

[tex]y-y_{1} =m(x-x_{1} )[/tex]

where y1 is the y coordinate from our point and x1 is the x coordinate from our point.  m is the slope.  That m has to be positive, according to the instructions.  So the first equation and the last one are out, since those are both negative.

If we fit our point into the point-slope form, it looks like this:

[tex]y-(-8)=4(x-(4))[/tex]

which simplifies to

[tex]y+8=4(x-4)[/tex]

Answer:

C) very likely

Step-by-step explanation:

Out of the 20 balls inside of the bag, 18 of them are green.

That means you have a 18/20 or 90% chance of getting a green ball.

Therefore, the probability of drawing a green ball is [tex]90[/tex] % then the option (C) is correct i.e., very likely.

What is the probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.

Here given that,

A bag contains [tex]2[/tex] red balls and [tex]18[/tex] green balls. A ball is chosen at random from the bag.

So,the total balls are [tex]18+2=20[/tex]

Green balls are [tex]18[/tex].

So the probability is

[tex]\frac{18}{20}[/tex] ×[tex]100=90[/tex] %

Hence, the probability of drawing a green ball is [tex]90[/tex] % then the option (C) is correct i.e., very likely.

For this case we must solve the following equations:

[tex]5x + 7 = 3x + 21[/tex]

We subtract 3x on both sides of the equation:

[tex]5x-3x + 7 = 21[/tex]

We subtract 7 on both sides of the equation:

[tex]5x-3x + 21-72x = 14[/tex]

We divide between 2 on both sides of the equation:

[tex]x = \frac {14} {2}\\x = 7[/tex]

The second equation is:

[tex]3x-2 (5-x) = - 3 (x-10) + 3x[/tex]

We apply distributive property to the terms of parentheses:

[tex]3x-10 + 2x = -3x + 30 + 3x[/tex]

We add common terms:

[tex]5x-10 = 30[/tex]

We add 10 to both sides of the equation:

[tex]5x = 30 + 10\\5x = 40[/tex]

We divide between 5 on both sides of the equation:

[tex]x = \frac {40} {5}\\x = 8[/tex]

Third equation:

[tex]5 (x + 1) = 3 (2x + 3) +5[/tex]

We apply distributive property to the terms within parentheses:

[tex]5x + 5 = 6x + 9 + 5[/tex]

We add similar terms:

[tex]5x + 5 = 6x + 14[/tex]

We subtract 6x on both sides of the equation:

Final answer:

a) The speed of the water at a point in the pipe with a radius of 0.210 m is 7.97 m/s. b) The radius of the pipe at a second point where the water speed is 2.80 m/s is approximately 0.209 m.

Explanation:

a) To find the speed of the water at a point in the pipe, we can use the equation Q = Av, where Q is the flow rate, A is the cross-sectional area of the pipe, and v is the velocity of the water. Given that the flow rate is 1.10 m³/s and the radius is 0.210 m, we can find the area using the formula A = πr². Substituting the values, we have A = 3.14(0.210)² = 0.138 m². Solving for v, we get v = Q / A = 1.10 / 0.138 = 7.97 m/s.

b) To find the radius of the pipe at a second point where the water speed is 2.80 m/s, we can use the equation v = Q / A. Rearranging the equation to solve for the radius, we have r = √(Q / (πv)). Substituting the values, we have r = √(1.10 / (π(2.80))) ≈ 0.209 m.

A sphere with radius [tex]r[/tex] has surface area [tex]4\pi r^2[/tex]. Divide the radius by 6 and you get a surface area of [tex]4\pi\left(\dfrac r6\right)^2=\dfrac4{36}\pi r^2[/tex], so that the final surface area is divided by 36.

We are given that E is 3 more than D. This means that to get the value of E, we will simply add 3 to the value of D

Therefore:

E = D + 3

Part B:

We are given that F is 5 less than D. This means that to get the value of F, we will simply subtract 5 from the value of D

Therefore:

F = D - 5

Part C:

To get the value of E-F, we will simply subtract the equation we obtained from part B from the equation we obtained from part A

Therefore:

E - F = (D+3) - (D-5)

E - F = D + 3 - D + 5

E - F = 8

The expression for 'e' in terms of 'd' is e = d + 3. The expression for 'f' in terms of 'd' is f = d - 5. The difference between 'E' and 'F' is 8.

A) e = d + 3
To express 'e' in terms of 'd,' we can simply say that 'e' is equal to 'd' plus 3. This is because the question states that 'E is 3 more than D.'

B) f = d - 5
To express 'f' in terms of 'd,' we can say that 'f' is equal to 'd' minus 5. The question states that 'F is 5 less than D.'

C) E - F = (d + 3) - (d - 5) = d + 3 - d + 5 = 8
To find the difference between 'E' and 'F,' we can substitute the expressions we found for 'e' and 'f' into the equation. Simplifying the expression further, we have 'E - F = (d + 3) - (d - 5) = d + 3 - d + 5 = 8.'

Answer:

89.0°

Step-by-step explanation:

The segment from the centre of the circle to the chord is a perpendicular bisector, hence

third side of right triangle = 12.7 ÷ 2 = 6.35

The angle subtended at the centre by arc CD is twice the angle subtended by the right triangle at the centre

The triangle from the centre to C is congruent to the triangle from the centre to D

Calculate the angle (Θ ) in the right triangle using the sine ratio

sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{6.35}{9.06}[/tex]

Θ = [tex]sin^{-1}[/tex] ( [tex]\frac{6.35}{9.06}[/tex] ) ≈ 44.5°

Hence

measure of CD = 2 × Θ = 2 × 44.5 = 89.0°

Answer:

30°

Step-by-step explanation:

In m KÔL, the angle is Ô and angle Ô is actually 30 degrees ;)

Answer:

m∠KOL = 30°

Step-by-step explanation:

It is given that mKL = 90and mMN = 30∘.

If two secants intersect in the exterior of a circle, then the measure of the angle formed is half the difference of the measures of its intercepted arcs. So,  

m∠KOL= 1/2(mKL− mMN)

Substitute the given values and simplify.

m∠KOL= 1/2 (90∘−30∘)

= 1/2(60∘)

= 30∘

Therefor, m∠KOL=30∘.

Well yes but this doesn't belong in math by the way.
