Step-by-step explanation:

The length of GF if, G is the centroid of the triangle ABC is 26.

Simple polygons with three sides and three internal angles make up triangles. One of the fundamental geometric shapes, it is represented by the symbol and consists of three connected vertices.

Given:

G is the centroid of the triangle ABC,

The  line segment BD can be written as,

40 is 2x as long as 9x+2

The equation can be written as for the above statement.

40 = 2(9x + 2)

40 = 18x + 4

36 = 8x

x = 2

Put the value of x = 2 in 19X + 14, and divide that answer by 2, because GF is 2x smaller than AG

19x + 14

19 (2) + 14

52

Thus, the length of GF = 52 / 2 = 26.

Step-by-step explanation:

Answer:

Step-by-step explanation:

If our interval is between 0 and 90 degrees, that means that our angles are first quadrant angles.  Since the formulas for the half angles of sin and cos consider both the positive and negative roots, knowing that we are in QI leaves us using only the principle, or positive, root.  

Also, if we know that the sin of angle is 3/4, we can set up a right triangle in QI and find the missing side of that triangle using Pythagorean's Theorem. Sin of an angle is the ratio opposite side/hypotenuse.  That means that, according to Pythagorean's Theorem,

[tex]4^2=3^2+b^2[/tex] and

[tex]16-9=b^2[/tex] and

[tex]b=\sqrt{7}[/tex]

Now for the forula for the sin of a half-angle:

[tex]sin(\frac{\theta}{2})=\sqrt{\frac{1-cos\theta}{2} }[/tex]

Referring to the right triangle we created and found the missing side for, we see that the cosine of that same triangle is [tex]\frac{\sqrt{7} }{4}[/tex]

Filling in the formula then:

[tex]sin(\frac{\theta}{2})=\sqrt{\frac{1-\frac{\sqrt{7} }{4} }{2} }[/tex]

Get a common denominator on the upper fraction:

[tex]sin(\frac{\theta}{2})=\sqrt{\frac{\frac{4-\sqrt{7} }{4} }{2} }[/tex]

Bring up the 2 as 1/2 to multiply and get:

[tex]sin(\frac{\theta}{2})=\sqrt{\frac{4-\sqrt{7} }{8} }[/tex]

When you do the exact same thing to find the cos of the half angle, you are using a + sign instead of a - sign under the radical.  That gives you as your exact value:

[tex]cos(\frac{\theta}{2})=\sqrt{\frac{4+\sqrt{7} }{8} }[/tex]

Area of circular pipe in terms of pi is found as [tex]100 \pi[/tex] square centimeter

Solution:

Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm

We have to find the area 'A' of the circular cross-section of the pipe.

Given, diameter of the circular section is:

diameter = 20 cm

Let us find the radius

[tex]radius = \frac{diameter}{2}\\\\r = \frac{20}{2} = 10[/tex]

Thus radius = r = 10 cm

The area 'A' of the circular cross-section of the pipe measn we can use the area of circle formula

The area of circle is given as:

[tex]area = \pi r^2[/tex]

Where "r' is the radius of circle

We have to find area in terms of pi

[tex]area = \pi (10)^2\\\\area = \pi \times 10 \times 10\\\\area = 100 \pi[/tex]

Thus area of circular pipe in terms of pi is found as [tex]100 \pi[/tex] square centimeter

Step-by-step explanation:

To answer this question we just simply use the distributive property to get rid of the parenthesis.

1.5*3x=4.5x

1.5*4=6

So the first parenthesis cancelled out would be : 4.5x+6

Now, onto the second:

0.25*6x=1.5x

0.25*8=2  

So the second one is : 1.5x+2

Not that we have distributed both things, we add these.

4.5x+6+1.5x+2 we combine like terms

4.5x+1.5x=6x

6+2=8

Answer:

Disjoint, because the events cannot occur at the same time.

Step-by-step explanation:

disjoint events are mutually exclusive events.

if a and b are two events then a intersection b will be 0 . they cannot occur at the same time.

here in the given problem let the event A be randomly drawing a jack from a standard deckn of card and evnt B be randomly drawing an ace from a standard deck of card.

since in a same card jack and ace cannot occur they are disjoint events.

therefore randomly drawing a jack from a standard deck of cards  and randomly drawing an ace from a standard deck of cards are disjoint events because the events cannot occur at the same time.

The two events are disjoint because a card from a standard deck cannot be both a jack and an ace at the same time. That is, these events cannot occur simultaneously.

In the given scenario, the two events - randomly drawing a jack from a standard deck of cards and randomly drawing an ace from a standard deck of cards - are disjoint. This is because these are separate and distinct events which cannot occur simultaneously. In terms of probability theory, two events are considered disjoint if the occurrence of one event excludes the possibility of the occurrence of the other event. In a standard deck of cards, a card cannot be both a jack and an ace at the same time.

Answer:

the equation rearranged with [tex]\( u \)[/tex] as the independent variable is:

[tex]\[ u = -\frac{6}{7}w \][/tex]

Step-by-step explanation:

To rearrange the equation so that [tex]\( u \)[/tex] is the independent variable, we need to isolate [tex]\( u \)[/tex] on one side of the equation.

Starting with the given equation:

[tex]\[ 4u + 8w = -3u + 2w \][/tex]

First, add [tex]\( 3u \)[/tex] to both sides to get all the [tex]\( u \)[/tex] terms on one side:

[tex]\[ 4u + 3u + 8w = -3u + 3u + 2w \][/tex]

[tex]\[ 7u + 8w = 2w \][/tex]

Next, subtract [tex]\( 8w \)[/tex] from both sides to get all the [tex]\( w \)[/tex] terms on the other side:

[tex]\[ 7u + 8w - 8w = 2w - 8w \][/tex]

[tex]\[ 7u = -6w \][/tex]

Finally, divide both sides by [tex]\( 7 \)[/tex] to solve for [tex]\( u \)[/tex]:

[tex]\[ \frac{7u}{7} = \frac{-6w}{7} \] \[ u = -\frac{6}{7}w \][/tex]

So, the equation rearranged with [tex]\( u \)[/tex] as the independent variable is:

[tex]\[ u = -\frac{6}{7}w \][/tex]

This is the final answer, with [tex]\( u \)[/tex] isolated on one side of the equation.

Answer: 14 butterflies per hour

Step-by-step explanation: "Per hour" means in 1 hour so we can rewrite the given statement using fractions.

42 butterflies over 3 hours = ___ butterflies per hour.

I have attached my work in the image provided.

To find out what goes in the blank, notice that we have a 1 in the denominator of our second fraction. So we want to find a fraction that is equivalent to 42/3 that has a 1 in the denominator.

If we divide the numerator and denominator of 42/3 by 3, we get the equivalent fraction 14/1 or 14 butterflies over 1 hour. So now we have 14 butterflies over 1 hour = ___ butterflies per hour.

Now we can easily see that a 14 must go in the blank which means that the unit rate for 42 butterflies in 3 hours is 14 butterflies per hour.

16351= [tex]1+6,6-3,3\times 5,\frac{5}{1} = 73155[/tex]

73155= [tex]7+3, 3-1, 1\times 5, \frac{5}{5} = 10251[/tex]

10251

The missing number in the sequence '88511, 16351, ?, 10251' is 60809, as the pattern in this sequence is to subtract 77160 from the previous number and take its absolute value.

This is an example of a number sequence problem. Let me explain how we can find the missing number in the sequence '88511, 16351, ?, 10251'. To solve this, we need to identify the pattern used to generate this sequence. In this case, it appears the number 77160 (88511 - 16351) is subtracted to get the next number.

So if we subtract 77160 from 16351, we get -60809. But given the pattern of the sequence, all numbers are positive. Therefore, we need to take the absolute value of the result to fit the sequence. So our missing number would then be 60809.
