If you spin the spinner 24 times, what is the best prediction possible for the number of times it will land on yellow?
LOOK AT THE IMAGE
Answer:
0
Explanation:
If the spinner has 4 green sections in a circle and you spin it 24 times, the best prediction for the number of times it will land on yellow is 0. Since there are no yellow sections mentioned, it is unlikely for the spinner to land on yellow.
Answer: 0
Step-by-step explanation:
There's no yellow, so it's not possible to spin yellow.

What is the area of the rhombus?
378 cm2
189 cm2
126 cm2
77.8 cm2
Step-by-step explanation:
The area of a rhombus is given by the formula A = (1/2)bh, where b is the length of the base and h is the height.
In this case, the base is 20 centimeters and the height is 18.9 centimeters. So, the area of the rhombus is:
A = (1/2)(20)(18.9) = 189 square centimeters
Therefore, the answer is option B: 189 cm2.

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is red.
spinner divided evenly into eight sections numbered 1 through 8 with three colored blue, one red, two purple, and two yellow
Determine the theoretical probability of the spinner landing on yellow, P(yellow).
0.125
0.25
0.625
0.75
The spinner has a total of 8 sections, out of which 2 sections are yellow. Therefore, the theoretical probability of the spinner landing on yellow is:
P(yellow) = Number of favorable outcomes / Total number of outcomes
= 2/8
= 1/4
= 0.25
Therefore, the answer is option B: 0.25.

Georgia Connections Academy is selling tickets to its Spring Fling. Adult tickets cost $4 and student tickets cost $2.50. The school makes $2,820. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold.
Answer:
Step-by-step explanation:
We use a for Adult and s for Student.
Assuming this, you have to start by writing two equations from the information provided:
900 total tickets were sold
a+s=900 ------(i)
they made $2,820 and adult tickets cost $4 and kids tickets cost $2.50
2820=4a+2.5s ------(ii)
lets solve for a in the first equation:
a=900-s
we can plug this into the second equation and solve for s
2820=4(900-s)+2.5s
2820=3600-4s+2.5s
2820=3600-1.5s
-780=-1.5s
s=520
we can plug this into the first equation and solve for a:
a+520=900
a=380
Total adult ticket sold : 380
Total student ticket sold = 520
Cost of adult tickets = 380 * 4 = $1520
Cost of student tickets = 520 * 2.5 = $1300

After 1 year, $50,000 deposited in a savings account with simple interest had earned $2,500 in interest. What was the interest rate?
pls explain how as well if you don't mind
Answer:
5%
Step-by-step explanation:
The formula for calculating simple interest is:
Interest = Principal × Rate × Time
Where:
Interest is the amount of money earned as interest
Principal is the initial amount of money deposited
Rate is the interest rate (expressed as a decimal)
Time is the duration for which the money is invested or the time period over which interest is calculated
In this scenario, the principal amount is $50,000, and the interest earned is $2,500. The time period is given as 1 year.
We can rearrange the formula to solve for the rate:
Rate = Interest / (Principal × Time)
Plugging in the given values:
Rate = $2,500 / ($50,000 × 1)
The calculation simplifies to:
Rate = $2,500 / $50,000
Dividing $2,500 by $50,000 gives us the decimal value of the interest rate:
Rate = 0.05
To express the interest rate as a percentage, we multiply the decimal value by 100:
Rate = 0.05 × 100
Rate = 5%
Therefore, the interest rate for the savings account is 5%.
Answer:
Interest Rate = 5%
Step-by-step explanation:
Principal = $50, 000
Rate = ?
Time = 1 yr
S.I = PRT/100
2,500/1 = 50,000 × R × 1/100
50,000R = 2,500 × 100
50,000R = 250,000
50,000R/50,000 = 250,000/50,000
R = 5 %

Write the prime factorization of 60. Use exponents when appropriate and order the factors from least to greatest
Answer:
2^2 x 3 x 5
Step-by-step explanation:
60 breaks down to 6 x 10. 6 can be divided down to 2 x 3. 10 can be broken down to 2 x 5. 2 x 3 x 2 x 5 should equal 60 then the numbers that show up twice match together and an exponent is added 2 x 2 becomes 2^2.
The prime factorization of 60. Using exponents when appropriate and order the factors from least to greatest is: [tex]\sf 2^2\times3\times5[/tex].
ExponentGiven:
Prime factorization = 60
Hence:
Now let find or determine the prime factorization of 60 by making use of the exponents appropriately or correctly:
[tex]\sf 2^2\times3\times5[/tex]
[tex]\sf 2^2\times15[/tex]
Or
[tex]\sf 2^2\times3\times5[/tex]
[tex]\sf 2^2\times15[/tex]
Based on the above calculation it implies that 2 raise to power of 2 times 15 will gives us 60. The raise to power of 2 is the exponent.
Therefore the prime factorization of 60. Using exponents when appropriate and order the factors from least to greatest is: [tex]\sf 2^2\times3\times5[/tex].

Answer:
She needs 9 bags (8.75 specifically) to fill the space around the photo box.
Step-by-step explanation:
Volume of rectangular box = length x width x height = 12.5 in x 4.2 in x 12.5 in = 656.25 cubic inches
Subtracting the volume of the photo box from the volume of the rectangular box, we get:
The volume of packing material = Volume of the rectangular box - Volume of the photo box
Volume of packing material = 656.25 cubic inches - 0 cubic inches = 656.25 cubic inches
Therefore, the number of bags needed is:
Number of bags = Volume of packing material / Volume of one bag
Number of bags = 656.25 cubic inches / 75 cubic inches per bag = 8.75 bags
Rounding up to the nearest whole number, Sasha needs to buy 9 bags of packing material to fill the space around the photo box.

96 - x = 64
ninety minus ? equals sixty four
Hello!
96 - x = 64
96 - x + x = 64 + x
96 = 64 + x
96 - 64 = 64 + x - 64
x = 32
ninety six minus ? equals sixty four
? = 96 - 64 = 32
Answer: x = 32
Step-by-step explanation: By using inverse operations, you may separate the variable x from the other variables in equation 96 - x = 64. Let's tackle it piece by piece:
Let's begin with the formula 96 - x = 64.
We must get rid of the 96 on the left side of the equation in order to focus on the variable x. 96 can be taken out of both sides of the equation to accomplish this: (96 - x) - 96 = 64 - 96.
To put it simply, -x = -32.
We want to remove the minus sign from the front of x so that we can solve for x. By multiplying both sides of the equation by -1, we can do this:
(-1)(-x) = (-1)(-32).
So, if we simplify, we get x = 32.
As a result, x = 32 is the answer to the equation 96 - x = 64.
