Answer 1

Answer:

The answer is letter D

Step-by-step explanation:

Answer 2

Answer:

7x+3x=10x

-6(x-7)= -6x+42

then 10x+12=-6x+42+9x

10x+12=3x+42

10-3=42_12

7x=30

then the correct answer is C

Around which line would the following cross-section need to be revolved to create a sphere?

circle on a coordinate plane with center at 1 on the x-axis and a radius of 1

y = x
y-axis
x = 1
y = 1

Answers

Answer:

I believe your answer would be y=1.

Step-by-step explanation:

The circle is located with its point on 1 of the x axis, and the cross section would be pulled straight from that term. So the cross section would need to be revolved around y = 1, instead.

This is just my best guess, so I hope it helps!

To get a sphere, we need to do a revolution around the line x = 1.

Which line should we use?

The line that we must use must be a line that divides the circle in two equal parts, so it must pass through its center.

We know that the center of our circle is the point (1, 0).

With that in mind, the two lines that we know that will divide the circle in two equal parts are:

y = 0x = 1

(There are more lines, the above two are the simplest ones).

The only one that appears on the options is x = 1, so that is the correct option.

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles
A = 59°, a = 13, b = 14

Answers

angle A = 59o and sides a = 13, b = 14.
Lets find remaining angles are B and C and the remaining side c.
Law of sines : a/sinA = b/sinB ⇒ sinB = (b*sinA)/a
sinB = (14*sin59o)/13 = (14*0.857167)/13 ≅ 0.923
B ≅ sin-1(0.923) ≅ 67.384.
There are two triangles, B₁ = 67.4 and B₂ = 180 - 67.4 = 112.6
find the angle c for B₁ = 67.4
A+ B +C = 180.
Angle C = 180 - (59 + 67.4) = 53.6.
Law of sines : b/sinB = c/sinC ⇒ c = b*sinC/sinB
c = (14)*sin(53.6)/sin(67.4) = (14)*(0.805)/(0.923) = 12.21.

find the angle c for B₂ = 112.6
A+ B +C = 180.
Angle C = 180 - (59 + 112.6) = 8.4.
Law of sines : b/sinB = c/sinC ⇒ c = b*sinC/sinB
c = (14)*sin(8.4)/sin(112.6) = (14)*(0.146)/(0.9232) = 2.27.

Answer:

67.4°, C = 53.6°, c = 12.2; B = 112.6°, C = 8.4°, c = 2.2

a/sinA=b/sinB=c/sinC

a/sinA=13/0.8572=15.1662

sinB=b/a *sinA

sinB=14/13 *sin59=0.9231

B=67.4

B1=90+22.6=112.6

because sin67.4=sin112.6=0.9231

C=180-59-67.4=53.6

C1=180-59-112.6=8.4

c=a* sinC/sinA=13* sin53.6/sin59=12.2

c1=a* sinC1/sin59=13*sin8.4/sin59=2.2

This circle graph shows how Jimmy spent his time during the last 24 hours.


How much more time did he spending watching T.V. and Talking on the Phone than he did Going to School?
8 hours
5 hours
1.92 hours
1.2 hours

Answers

Answer:

Excess time = 1.2 hour

Step-by-step explanation:

Given:

Total time = 24 hours

Talking on phone = 17 %

Sleeping = 33%

Going to school = 25%

Studying = 4%

Eating = 8%

Computation:

Watching TV percent = 100% - Talking on phone - Sleeping - Going to school - Studying -  Studying - Eating

Watching TV percent = 100% - 17% - 33% - 25% - 4% - 8%

Watching TV percent = 13%

Time taken by school = 24 x 25%

Time taken by school = 6 hour

Time taken by watching T.V. and Talking on the Phone = 24 x (13% + 17%)

Time taken by watching T.V. and Talking on the Phone = 7.2 hour

Excess time = 7.2 - 6

Excess time = 1.2 hour

The cost of tickets to a school play are $10 for adults and $6 for children under 12. If there were a total of 100 tickets sold to the play on a certain night, what equation would you use to represent the total ticket sales, T, if the number of adult tickets can be represented by a. Show and explain each step to create the equation.

Answers

Answer:

10a+6b=T------------2

Step-by-step explanation:

Given data

Let the number of adults be a

and the number of children be b

we are told that the total tickets is 100

hence

x+y=100-------------1

The cost of adult ticket = $10

The cost of children ticket = $6

since the total cost is T

Hence

10a+6b=T------------2

Figuring out the slope:

Since we have the two points, we would need to use the slope formula of:

So it would be (-6 - 0) divided by (0 - 6) = -6/-6 = 1
