Answers

Answer:

How much of the project should still be completed? And who do you think should do the last section of the project?

Answers

Answer:

the project has been completed.

Step-by-step explanation:

5/18 +4/18 + 9/18 = 18/18 or 1

ride costs $5 plus $2.50 per mile. How
many mile can Bryan go without spending
all $15?

Answers

Answer:

3 full miles; anything less than 4 miles

Step-by-step explanation:

5 + 2.50x = 15

subtract 5 from both sides

2.50x = 10

divide both sides by 2.50

x = 4

4 miles is how long he can travel by spending all $15

Anything less will cost him less than $15

An ice skating show earned 15,385 in one night. Tickets for the show cost $25 for adults and $15 for children. The number of adults who attendee the shw was 41 more than the number of children who attended the show. How many adults and children attended the show?

Answers

Answer:

Number of adults that attended the show = 400

Number of children that attended the show = 359

Total people who attended the show = 759

Step-by-step explanation:

Total earned = 15,385

Adults = $25

Children = $15

Let

Adults = A

Children = C

The number of adults who attendee the show was 41 more than the number of children who attended the show

A = C + 41

25A + 15C = 15,385

Substitute

A = C + 41

25(C+41) + 15C = 15,385

25C + 1,025 + 15C = 15,385

40C + 1,025 = 15,385

40C = 15,385 - 1,025

40C = 14,360

Divide both sides by 40

C = 14,360 / 40

= 359

C = 359

Substitute C = 359 into

A = C + 41

A = 359 + 41

= 400

A = 400

Number of adults that attended the show = 400

Number of children that attended the show = 359

Total people who attended the show = 759

If (x^2 2 x 1) is singular and (x 2x 3x 4x) is non-singular, find the value of x.

Answers

I assume you're talking about two square matrices,

[tex]A=\begin{bmatrix}x^2&2\\x&1\end{bmatrix}[/tex]

and

[tex]B=\begin{bmatrix}x&2x\\3x&4x\end{bmatrix}[/tex]

If A is singular, then its determinant is 0:

[tex]\det A=x^2-2x=x(x-2)=0\implies x=0\text{ or }x=2[/tex]

B is not singular, so its determinant is not 0:

[tex]\det B=4x^2-6x^2=-2x^2\neq0[/tex]

This tells you x ≠ 0, so x = 2.

At a baking competition, 0.5 dishes were cooked by Room 102, 3/10 were cooked by Room 104, and 1/5 were cooked by Room 106. What fraction of the dishes were cooked by Rooms 102 and 104? Express your answer in the simplest form.​

Answers

1/2 (room 2) + 3/10 (room 4) = 8/10

Simplifying the fraction: 4/5

Answer would be 4/5 of the dishes were cooked by rooms 102 and 104

Hope it helps! Good luck!

Mark me as brainliest pls!

The fraction of the dishes were cooked by Rooms 102 and 104 is 4/5

Addition of fraction

Dishes cooked by Room 102 = 0.5 = 1/2

Dishes cooked by Room 104 = 3/10

Dishes cooked by Room 106 = 1/5

Fraction of the dishes were cooked by Rooms 102 and 104 = 1/2 + 3/10

= (5+3) / 10

= 8 / 10

= 4 / 5

Therefore, the fraction of the dishes were cooked by Rooms 102 and 104 is 4/5 in the simplest form

Answer:

v=8

Step-by-step explanation:

12=12+v−8/2

12=12+1/2

v+−4(Distribute)

12=(1/2v)+(12+−4)(Combine Like Terms)

12=1/2v+8

Step 2: Flip the equation.

1/2v+8=12

Step 3: Subtract 8 from both sides.

1/2v+8−8=12−8

Step 4: Multiply both sides by 2.

2*(1/2v)=(2)*(4)

v=8

12 = 12 + (v - 8)/2
Subtract 12 from both sides
0 = (v - 8)/2
Multiple both sides by 2
0 = v - 8
Add 8 to both sides
8 = v
Therefore A is correct

many weeks will Sara and Kevin have the same number of paintings? *

O 14 weeks

Answers

Answer:

If Sara has 2 painting already and paints 3 more each week, and Kevin has 12 paintings already and paints 2 more each week, we go down the list of answers and multiply them by the number of paintings painted each week. So first is 12x2=24 24+12=36    then 12x3=36 36+2=38   now we do 10x2=20 20+12=32   10x3=30 30+2=32 so your answer would be 10 weeks

In 2005, MusicMart sold 14,550 CDs. In 2010, they sold 12,000 CDs. What is the rate of change in the number of CDs sold?
A) -2550 per yr B) -510 per yr C) -425 D) -2400 per yr

Answers

Answer:

B) -510 per yr

Step-by-step explanation:

2005 = 14,550 CDs sold

2010 = 12,000 CDs sold

Difference in years = 2010 - 2005

= 5 years

Difference in CDs sold = 12,000 - 14,550

= - 4,550

Rate of change in the number of CDs sold = change in the number of CDs / change in years

= -4,550 / 5

= -510 per year

The correct answer is B) -510 per yr
