Jason bought 12 new CDs to add to his
collection. The next day, his baby

has 56 working CDs left. How many
CDs did Jason start with?

He had origanlly had 68 altogether
Step-by-step explanation:
Because if u count the scrateched ones which was 6 is now 62 then add the other six because there was 12 and his brother scrateched half which is basically 12 / 2 = 6 so if u add the six is 68
What Im basically saying is 56 + 12 = 68
Which number has the greatest value -17, -24 ,0, 23?
Answer:
23
Step-by-step explanation:
Example:
You have no money, you decide to swipe your credit card to purchase something for $17. Again, you did so for another item paying $24. You are now $41 in debt. Your mom decides to pay for your debt which is $41. You decide to actually go to your part-time job and earn $23. When was the time you had the most money in this example? When you earned the $23 becuase you started with none.
Answer:
23
Step-by-step explanation:
Out of the numbers given:
All positive numbers are greater than negative numbers.
This eliminates -17 and -24.
Comparing 0 to 23:
23 has more value than 0.
0 < 23
This means out of the numbers given, 23 has the greatest value.

The number of people I don’t know amusement park triples every hour. This morning, there were 20 people at the muse meant park when it opened. Now, there are 4860 people have them use meant park. Write an equation to represent the number of hours the amusement park has been open.
Answer:
equation is y=20(3)^x
Step-by-step explanation:
example:
Solve for x over the integers:
20 (3)^x = 4860
Divide both sides by 20:
3^x = 243
243 = 3^5:
3^x = 3^5
Equate exponents of 3 on both sides:
Answer:
x = 5 hours open with 4860 guest
Gina earns an hourly rate of $8.94 for a 40-hour week. She receives
double-time (2 times the hourly rate) for any weekend work. This week
she worked his regular 40 hours plus 10 hours on Saturday. Calculate her
gross pay.
Answer: $536.40
Step-by-step explanation:
8.94 * 2 = 17.88
8.94(40) + 17.88(10)
357.60 + 178.80 = $536.40

Write your answer in centimeters.
cm
X Х
5
?
Meters to centimeters
Answer:
It grows 221 centimeters in 13 weeks.
Step-by-step explanation:
Each meter has 100 centimeters.
A coral reef grows 0.17 m every week
So it grows 0.17*100 = 17 cm every week.
How much does it grow in 13 weeks?
17 cm every week for 13 weeks, so
17*13 = 221
It grows 221 centimeters in 13 weeks.
URGENT I'll give you stars, brainliest answer, or slide into ur dms for this answer pls9^(x2)=y in log form
Answer:
log ( 28 )
13 √ 25
log
( 1/ 2 )
Step-by-step explanation:
To solve this, we will use this property of logarithms:
If x= a ^ y
then log an (x) = y, where a is the base
So if e^9 = y , or y = e^9
then log e (y) = 9
NB: log e (y) is also referred to as the natural log of y, or ln y.
So it can also be written as:
Answer: ln y = 9, or log e (y) = 9

find the value of x
Answer:
x = 5
Step-by-step explanation:
These angles are supplementary so:
9x + 12x + 75 = 180
21x + 75 = 180
21x = 180 - 75
21x = 105
x = 5

Find the 110 term of the sequence -7,3, 13, 23, ..
Answer:
1083
Step-by-step explanation:
The formula for the nth term of a sequence is a+(n - 1 )d, where a is the first term and d is the difference between each term. Here, a is -7 and d is 10 (terms go up by ten each time).
So, the nth term = -7+(n-1)10 = -7+10n-10 = 10n-17
So, the 110th term = 10(110)-17=1100-17=1083
Rosa is making a poster that has a rainbow as part of the design. Using a compass she draws a semicircle with a radius of 18 cm. She draws another semicircle that has a radius of 12 cm as shown. What is the area of the shaded part of the rainbow?
Answer:
282.7 cm²
Step-by-step explanation:
Hello There!
To find the area of the shaded area we are going to want to find the area of the whole semi circle and subtract it by the area of the smaller semi circle
To find the area of a semicircle we use this formula
[tex]A=\frac{\pi r^2}{2}[/tex]
where r = radius
For the large semi circle
The radius of the larger semi circle is 18 cm so we plug in 18 into r in the formula
So..
[tex]A=\frac{\pi 18^2}{2} \\18^2=324\\324\pi =1017.87602\\\frac{1017.87602}{2} =508.9380099[/tex]
So the area of the whole semi circle is 508.9380099 cm²
Now to find the area of the smaller semi circle
The radius for the smaller semi circle is 12 cm so we plug in 12 into r in the formula
[tex]A=\frac{12^2\pi }{2} \\12^2=144\\144\pi =452.3893421\\\frac{452.3893421}{2} =226.1946711[/tex]
so the area of the smaller semi circle is 226.1946711cm²
Finally we want to subtract the area of the smaller semi circle from the area of the whole semi circle
508.9380099 - 226.1946711 = 282.7433388
Finally we want to round to the nearest tenth and we get that the area of the rainbow is 282.7 cm²

Answer:
99°
Step-by-step explanation:
Triangle=180°
Given, 41+40=81
180-81
Answer:
99°
Step-by-step explanation:
Sum of angles in a triangle is supplementary,
x + 41° + 40° = 180°
x + 91° = 180°
x = ( 180 - 91 )
x = 99°

You are testing the claim that the mean GPA of night students is different from the mea GPA of day students. You sample 20 night students, and the sample mean GPA is 2.84 with a standard mean GPA is 2.55 with a standard deviation of 0.45. Test the claim using a 1% level of significance. Assume the population standard deviations are unequal and that GPAs are normally distributed. Give answer to at least 4 decimal places. What are the correct hypotheses
Answer:
As the calculated value of z does not lie in the critical region the null hypothesis is accepted that the GPA mean of the night students is the same as the GPA mean of the day students.
Step-by-step explanation:
Here n= 20
Sample mean GPA = x`= 2.84
Standard mean GPA = u= 2.55
Standard deviation = s= 0.45.
Level of Significance.= ∝ = 0.01
The hypothesis are formulated as
H0: u1=u2 i.e the GPA of night students is same as the mean GPA of day students
against the claim
Ha: u1≠u2
i.e the GPA of night students is different from the mea GPA of day students
For two tailed test the critical value is z ≥ z∝/2= ± 2.58
The test statistic
Z= x`-u/s/√n
z= 2.84-2.55/0.45/√20
z= 0.1441
As the calculated value of z does not lie in the critical region the null hypothesis is accepted that the GPA mean of the night students is the same as the GPA mean of the day students.
