Answer:

[tex]\mathbf{y^2 -z^2 =1- n^2}[/tex]

Step-by-step explanation:

Give that:

the surface equation is  [tex]x^2 +y^2 -z^2 =1[/tex]

from the family of traces in x = n given that [tex]x^2 +y^2 -z^2 =1[/tex] , the equation can be represented as :

[tex]n^2 +y^2 -z^2 =1[/tex]

[tex]\mathbf{y^2 -z^2 =1- n^2}[/tex]

This represents a family of hyperbola for all values of n expects that n = ± 1

So, if n = ± 1,

Then

[tex]y^2 - z^2 = 0[/tex]

(y-z) (y+z) = 0

y = ± z

So, for n = ± 1, it is a pair of line for y = z, y = -z

Angle C is 31, Angle A is 30, and Angle B is 119.

Step-by-step explanation:

The measures of each of the angles in triangle ABC are

A = 18

B = 83

C = 79

From the question, we are to determine the measure of each of the angles in triangle ABC

From the given information,

The measure of angle B is 29 more than three times the measure of angle A

That is,

B = 3A + 29 ------- (1)

Also, the measure of angle C is 61 more than the measure of angle A

That is,

C = 61 + A --------- (2)

We can also write that

A + B + C = 180 ----- (3) (Sum of angles in a triangles)

Put equations (1) and (2) into equation (3)

A + 3A + 29 + 61 + A = 180

5A + 90 = 180

5A = 180 - 90

5A = 90

A = 90/5

A = 18

Put the value of A into equation (1)

B = 3A + 29

B = 3(18) + 29

B = 54 + 29

B = 83

Put the value of A into equation (2)

C = 61 + A

C = 61 + 18

C = 79

Hence, the measures of each of the angles are

A = 18

B = 83

C = 79

Here is the complete and correct question:

In triangle ABC, the measure of angle B is 29 more than three times the measure of angle A. The measure of angle C is 61 more than the measure of angle A. Find the measure of each angle.

SPJ2

Answer:

148

Step-by-step explanation:

A and B are alternate exterior angles and alternate exterior angles are equal when the lines are parallel

A = B

6x-2 = 4x+48

Subtract 4x from each side

6x-4x-2 = 4x+48-4x

2x-2 = 48

Add 2 to each side

2x-2 +2 = 48+2

2x = 50

Divide by 2

2x/2 = 25

We want to find angle A

A = 6x-2

   = 6*25 -2

    150 -2

  = 148

Answer:

Solution given:

<A=<B{alternate exterior angle are equal}

6x-2=4x+48

6x-4x=48+2

2x=50

x=50/2

x=25

<A=6×25-2=148°

Answer:

[tex]\boxed{\tt v= 6,020 \ mL}[/tex]

Step-by-step explanation:

The density formula is

[tex]d=\frac{m}{v}[/tex]

Rearrange the formula for v. Multiply both sides of the formula by v, then divide both sides by d.

[tex]d*v=\frac{m}{v}*v[/tex]

[tex]d*v=m[/tex]

[tex]\frac{dv}{d}=\frac{m}{d}[/tex]

[tex]v=\frac{m}{d}[/tex]

The volume can be found by dividing the mass by the density. The mass is 7525 grams and the density is 1.25 grams per milliliter.

[tex]m= 7525 \ g\\d=1.25 \ g/mL[/tex]

[tex]v=\frac{m}{d}[/tex]

[tex]v=\frac{7525\ g}{1.25\ g/mL}[/tex]

Divide. Note that the grams, or "g" will cancel each other out.

[tex]v=\frac{7525 \ }{1.25\ mL}[/tex]

[tex]v=6020 \ mL[/tex]

The volume of the rock is 6,020 milliliters.

Answer:

V = 6020

Step-by-step explanation:

will  make it sure and simple

formula of density d = mass / volume

where d = 1.25 g/mL

and mass = 7525 g

plugin values into the formula

1.25 = 7525 / Vol

Vol = 7525 / 1.25

Vol = 6020

Answer:

apart from using the hoc to predict the college students gpa, some other variables can be used

1. the students intelligent quotient

2. ability to remember

3. study time

4. gym practice

Step-by-step explanation:

1. the students intelligent quotient

gpa has a positive relationship with iq. they are both directly related. The more the iq of a a student, the greater is his ability to understand and have a good gpa. the slope will therefore be positive and be in an upward direction.

2. ability to remember

the gpa of students who have a good ability to remember but do not have a good grasp of the subject may not be high. the slope would be in a slightly upward direction

3. study time

gpa and practice have a positive relationship. the more a student studies, the more likelihood exists of having a better gpa. the slope would be upward bound.

4. gym practice

gpa and gym practice are not related so the slope would be in a downward direction.

when interpreting the direction of relationship after carrying out such an analysis, it is useful to watch out for the accompanying signs of the variables. if the sign of the beta coefficient is positive then a positive relationship with the dependent variable exists.

Answer:

$3.276

Step-by-step explanation:

From the question, we are told that the price of banana is

1 pound = $2.34

1.4 pounds = $ y

Cross Multiply

1 pounds × $y = 1.4 pounds × $2.34

$y = 1.4 pounds × $2.34/1 pounds

$y = $3.276

Therefore, a person will pay $3.276 for 1.4 pounds of banana

Answer: 2 pounds

Step-by-step explanation: hope this helps:)

The amount of pounds of fruit Sam and Maria has altogether is 2 pounds of fruits.

Sam buys 3 different types of fruit in 3/4 pounds basket,

Therefore, he has 3 / 4 pound weight of fruit.

Maria has 1 1/4 pound fruit. Therefore, the total weight Maria bought is 1 1 / 4 pounds.

1 1 / 4 = 5 / 4 pounds.

The total amount of fruit they have together is gotten by summing there weight in pounds.

Hence,

total weight = 3 / 4 + 5 / 4 =  3 + 5/ 4 = 8 / 4 = 2 pounds.

Therefore, the altogether they have 2 pounds of fruits.
