If angle 2 = 48, determine the measure of angle 5.
Answer:
Angle 2 = 48
we are going to divide 48 by 2 to get the Angle 1
Angle 1 = 24
then Angle 5 = (5×24)
Angle 5 = 120

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
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

Sara has 2 paintings in her portfolio and paints 3 more each week. Kevin
has 12 paintings in his portfolio and paints 2 more each week. After how
many weeks will Sara and Kevin have the same number of paintings? *
12 weeks
O 10 weeks
O 16 weeks
O 14 weeks
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

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

Corey is reading a graph of equivalent ratios. If one of the ratios is represented as (3, 5), which could be another ratio?
Answer:
another ratio is 3:5=6:10 or 9:15
Explanation:
3:5×2=6:10
3:5×3=9:15
Answer:
(9,15) aka C
Step-by-step explanation:
3 times 3 is 9 and so you multiply the same number to the y-coordinate. 5 times 3 is 15!
Bryan has $15 to spend on taxi fare. The
ride costs $5 plus $2.50 per mile. How
many mile can Bryan go without spending
all $15?
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 $15
Answer:
4 miles
Step-by-step explanation:
well we have a budget of 15$. We use 5$ for the ride so we have 10$ left. 10/2.5 is 4.

If (x^2 2 x 1) is singular and (x 2x 3x 4x) is non-singular, find the value of x.
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.
The fraction of the dishes were cooked by Rooms 102 and 104 is 4/5
Addition of fractionDishes cooked by Room 102 = 0.5 = 1/2Dishes cooked by Room 104 = 3/10Dishes cooked by Room 106 = 1/5Fraction 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

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?
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
