(3x+4)^2=0

3x+4=0

3x=-4

x= -4/3

Answer:

h = 12 m

[tex] v_{cylinder}= 235.5 \: {m}^{3} [/tex]

Step-by-step explanation:

Radius of cylinder (r) = 5/2 = 2.5 m

[tex] {h}^{2} = {13}^{2} - {5}^{2} \\ h = \sqrt{ {13}^{2} - {5}^{2} } \\ h = \sqrt{169 - 25} \\ h = \sqrt{144} \\ h = 12 \\ \\ v_{cylinder} = \pi {r}^{2} h \\ v_{cylinder}= 3.14(2.5) ^{2} (12) \\ v_{cylinder}= 235.5 \: {m}^{3} [/tex]

Answer:

it would be 200 points. Lets assume that all of the apprentice magicians are 143 years old. If so, then 143 x 7 = 1001. 1001 + 200 = 1201. 1021 ÷ 8 (the number of magicians) the answer is 150. so the age of head wizard is actually 200 years.

Answer:(x-0)^2 + (y-0)^2=30^2

Step-by-step explanation:

The equation of the circle is x^2 +y^2 = 7656.25

The given parameters are:

Center = (0,0)

Diameter = 175

The equation of a circle is represented as:

(x - a)^2 +(y - b)^2 = r^2

Where

Center = (a,b) = (0,0)

r = radius = 175/2

So, we have:

(x - 0)^2 +(y - 0)^2 = (175/2)^2

Evaluate

x^2 +y^2 = 7656.25

Hence, the equation of the circle is x^2 +y^2 = 7656.25

Answer:

x has to be equal to 12

Step-by-step explanation:

In other to prove that the triangles are similar, the values of the angles at certain points must be equal

for example, the angle at the top vertices should be equal

So, we have it that;

6x = 3x + 36

6x-3x = 36

3x = 36

x = 36/3

x = 12

hiiiiiiii

do u still need the answer or no cuz its kinda long

Answer:

Number 6 would be (a) 88 degrees

Number 7 would be (c) 45 degrees

Step-by-step explanation:

What is this Geometry? I haven't done this in so long so i went to look it up online and was shocked because of how much i was overthinking it.

For number 6, since we already have the angle listed as 44 degrees, to find the arc degrees, we would multiply the 44 by two. The formula is basically mAB=2(m<C)=88.

For number 7, we already have the arc degrees, so we would have to divide by two in this case to find the angle. The formula for this would be m<X=1/2(mYZ)=45.

Answer and Step-by-step explanation:

We are given the side lengths, so all we have to do is multiply each rectangle's lengths and widths to get their areas, then add them together,

Top rectangle Area:

4 × 7 = 28

Bottom rectangle Area:

6 × 8 = 48

Now, we add them together.

Total Area:

28 + 48 = 76

The total area of the figure is 76 [tex]units^{2}[/tex].

Answer:

8x<80

Step-by-step explanation:

The teams are teams of 8, so 8x is how many people on a team (8) times total number of teams (x). You want it to be less than 80, because, as it said, fewer than 80 people signed up.

Answer:

centre of the circle(h,k)=(5,2)

radius(r)=10

Step-by-step explanation:

Now,

equation of the circle is giveb by (x-h)^2+(y-k)^2=r^2

or,(x-5)^2+(y-2)^2=(10)^2

or,x^2-10x+25+y^2-4y+4=100

or,x^2+y^2-10x-4y+29-100=0

or,x^2+y^2-10x-4y-71=0

Step-by-step explanation:

Trust me.

The probability that a randomly selected student is a junior who takes the bus is  [tex]\frac{1}{5}[/tex] .

Probability or chance is how likely something is to happen. If something has a low probability, it is unlikely to happen. If something has a high probability, it is likely to happen.

[tex]probability=\frac{number\ of\ favourable\ cases }{total\ number\ of cases}[/tex]

Given,

Total number of students = 100

Number of students who are juniors and take bus = 20

[tex]probability=\frac{number\ of\ favourable\ cases }{total\ number\ of cases}[/tex]

Probability of junior students who take bus =  [tex]\frac{20}{100}[/tex]

Probability of junior students who take bus =  [tex]\frac{1}{5}[/tex]

Hence, The probability that a randomly selected student is a junior who takes the bus is  [tex]\frac{1}{5}[/tex] .
