Which numbers are solutions to the equation 30=x2
? Select all that apply.

x=15

x is equal to 15
x=30−−√
x is equal to square root of 30
x=900
x is equal to 900
x=−15
x is equal to negative 15
x=−30−−√
x is equal to negative square root of 30
x=−900

Answers

Answer 1

Answer:

x = +√30

Step-by-step explanation:

Please write 30 = x squared as 30 = x^2.

If x^2 = 30, there are two solutions:  x = +√30 and x = -√30.

Several possible answers are given.    x=30−−√ is closest to the correct one, but must be written as x = √30.  Please ask someone how to find the "√" operator in Brainly.  Or, just write "sqrt(      )" instead.

B) 50°

Answers

Answer:

 ∠BFC = 50

Step-by-step explanation:

∠AFC = 90

∠AFB + ∠BFC = 90

40 + ∠BFC = 90

           ∠BFC = 90 - 40

          ∠BFC = 50

Answer: B-C

Step-by-step explanation:

I believe it is the angle of B-C becuase B-E is a strieght line which equals 180. Also EFD looks the same as AFB so it is 40. And DFC is 90 becuase of the square. So we take 180-40-90=50. And the only one that is not solved is B-C

What is the volume of corn held in this cone-shaped grain silo? Use 3.14 for π and round to the nearest cubic foot. Enter your answer in the box.

Answers

Answer:

3014 cubit foot

Step-by-step explanation:

Find the diagram attached

Volume of the cone = 1/3πr²h

r is the base radius of the cone

h is the height

Given

r = 6ft

Get the height using the pythagoras theorem

h² = 10² - 6²

h² = 100 - 36

h² = 64

h = √64

h = 8ft

Get the volume

Volume = 1/3πr²h

Volume = 1/3 * 3.14 * 6^2*8

Volume = 3.14 * 12 * 8

Volume =3,014.4

Volume = 3014 cubit foot to the nearest foot

The required statement by the details is an option (D) that half of the players are 24 or younger.

What is mean?

The mean of the values is the ratio of the total sum of values to the number of values.

Here,
We are given that the mean age of the members of a baseball team is 28 and the median age is 24. We can use this information to eliminate some answer choices.

Option (A) states that more than half of the players are older than 28. Since the median age is 24 and the ages range from 20 to 45, this option is not supported by the data.

Option (B) states that half of the players are 28 or older. Since the median age is 24 and the ages range from 20 to 45, this option is not supported by the data.

Option (C) states that the mode of the data is less than 28. We do not have enough information to determine the mode, so this option could be true or false.

Option (D) states that half of the players are 24 or younger. Since the median age is 24, this option is supported by the data.

Therefore, the best-supported statement by the facts is option (D) that half of the players are 24 or younger.

Answers

Answer:

x = 3 units

SV = 2 units

Step-by-step explanation:

In[tex] \odot Z[/tex] QR and ST are chords such that:

QR = ST = 4

That is both the chords are equal in measure.

Equal chords are at equal distance from the center of the circle. Therefore,

VZ = UZ

4x - 6 = 6

4x = 6 + 6

4x = 12

x = 12/4

x = 3 units

Since, perpendicular dropped from the center of the circle bisects the chord.

[tex] \therefore SV = \frac{1}{2} ST[/tex]

[tex] \therefore SV = \frac{1}{2} \times 4[/tex]

The required measures of the circle are:

mDF = 75, m∠FBE 105, mFC=60
m∠CBE = 45, mDAC = 225. m∠ABE=135

m∠ABF=120

What are the sections of the circle?

A section of a circle is a region enclosed by a chord and an arc of the circle. It is also called a circular sector. A circular sector is defined by its central angle, which is the angle between the two radii that form the sector, and its radius, which is the distance from the center of the circle to the endpoints of the sector.

Here,
A circle is shown,

mDF = 75  [shown in the image]

m∠FBE = 60 + ∠CBE

m∠FBE = 60 + ∠ABD     [∠ABD=∠CBE]

m∠FBE = 60 + 45             [∠ABD = 180 - 75-60]

m∠FBE = 105,

Similarly,

mFC=60, m∠CBE = 45, mDAC = 225, m∠ABE=135, and m∠ABF=120
