Answer:
187/6
Step-by-step explanation:
Simplify the following:
(7 + 1/4) 2^2 + (8 + 1/2 - 2)/3
2^2 = 4:
(7 + 1/4) 4 + (8 + 1/2 - 2)/3
Put 7 + 1/4 over the common denominator 4. 7 + 1/4 = (4×7)/4 + 1/4:
(4×7)/4 + 1/4 4 + (8 + 1/2 - 2)/3
4×7 = 28:
(28/4 + 1/4) 4 + (8 + 1/2 - 2)/3
28/4 + 1/4 = (28 + 1)/4:
(28 + 1)/4×4 + (8 + 1/2 - 2)/3
28 + 1 = 29:
29/4×4 + (8 + 1/2 - 2)/3
29/4×4 = (29×4)/4:
(29×4)/4 + (8 + 1/2 - 2)/3
(29×4)/4 = 4/4×29 = 29:
29 + (8 + 1/2 - 2)/3
Put 8 + 1/2 - 2 over the common denominator 2. 8 + 1/2 - 2 = (2×8)/2 + 1/2 + (2 (-2))/2:
29 + ((2×8)/2 + 1/2 + (2 (-2))/2)/3
2×8 = 16:
29 + (16/2 + 1/2 + (2 (-2))/2)/3
2 (-2) = -4:
29 + (16/2 + 1/2 + (-4)/2)/3
16/2 + 1/2 - 4/2 = (16 + 1 - 4)/2:
29 + ((16 + 1 - 4)/2)/3
16 + 1 = 17:
29 + ((17 - 4)/2)/3

13/2×1/3 = 13/(2×3):
29 + 13/(2×3)
2×3 = 6:
29 + 13/6
Put 29 + 13/6 over the common denominator 6. 29 + 13/6 = (6×29)/6 + 13/6:
(6×29)/6 + 13/6
6×29 = 174:
174/6 + 13/6
174/6 + 13/6 = (174 + 13)/6:

Answer: 187/6
Answer:
31 1/6
Step-by-step explanation:
7 1/4 × 2²+(8 1/2-2)÷3
Using PEMDAS
Parentheses first
7 1/4 × 2²+(6 1/2)÷3
Then exponents
7 1/4 × 4+(6 1/2)÷3
Changing the mixed numbers to improper fractions
7 1/4 = (4*7+1)/4 = 29/4 and ( 2*6+1)/3 = 13/2
29/4 × 4+(13/2)÷3
Multiply and divide from left to right
29 + 13/2÷3
Using copy dot flip
29 + 13/2 * 1/3
29 + 13/6
Changing back to a mixed number
13/6 = 12/6 + 1/6 = 2 1/6
29 + 2 1/6
Add
31 1/6
Many states run lotteries to raise money. A website advertises that it knows "how to increase YOUR chances of Winning the Lottery." They offer several systems and criticize others as foolish. One system is called Lucky Numbers. People who play the Lucky Numbers system just pick a "lucky" number to play, but maybe some numbers are luckier than others. Let's use a simulation to see how well this system works. To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number. Any value can be picked, but for this exercise, pick 1 as the lucky number. What proportion of the time do you win? Run 60 trials using the random numbers given below, starting with the first number. 89064 27308 64568 14121 98226 65388 58732 85801 69902 78431 10380 42006
Answer:
10 percent
Step-by-step explanation:
hello,
from this question, it has been stated that the lucky number is 1
from all of these values below we are to account how many times 1 appeared in these numbers have
89064, 27308, 64568 ,14121, 98226, 65388, 58732, 85801, 69902, 78431, 10380, 42006.
the total number of 1 is 6
= 6 x 1 divided by the number of trials 60
= 6 x 1/60
= 0.1
to get the proportion, we multiply 0.1 by 100
0.1 x 100
= 10%

6a + 8s = 102
14a + 4s = 150
each adult ticket costs 9 dollars
===================================================
Explanation:
6 adult tickets and 8 student tickets bring in $102, so that means 6a+8s = 102
14 adult tickets and 4 students tickets bring in $150, so 14a+4s = 150
The system of equations is
[tex]\begin{cases}6a+8s = 102\\14a+4s = 150\end{cases}[/tex]
If we multiply both sides of the second equation by -2, we get this updated system
[tex]\begin{cases}6a+8s = 102\\-28a-8s = -300\end{cases}[/tex]
Add the equations straight down
6a+(-28a) = -22a
8s+(-8s) = 0s = 0 ... the 's' terms go away
102+(-300) = -198
So we end up with the equation -22a = -198 and that solves to a = 9 after dividing both sides by -22.
Each adult ticket costs $9
If you want the value of s, then
6a+8s = 102
6(9)+8s = 102
54 + 8s = 102
8s = 102-54
8s = 48
s = 48/8
s = 6
Meaning each student ticket costs $6
Or you could use the other equation
14a+4s = 150
14(9)+4s = 150
126+4s = 150
4s = 150-126
4s = 24
s = 24/4
s = 6
We get the same value of s

23. A man and a woman share a prize of $1000 between them in the
ratio 1:4. The woman shares her part between herself, her mother
and her daughter in the ratio 2:1:1. How much does her daughter receive?
Number of parts = 1 + 4 = 5
Sum of all parts = $1000
Each part =
= 1000 ÷ 5
= $200
Money the man got =
= 200 × 1
= $200
Money the woman got =
= 200 × 4
= $800
The womans has $800 as her share .
Total parts = 2 + 1 + 1 = 4 parts
Sum of all parts = 800
Each part = 800 ÷ 4
Each part = 200
Then ,
The woman gets =
= 200 × 2
= $400
Her mother gets =
= 200 × 1
= $200
Her daughter gets =
= 200 × 1
= $200∴ Her daughter receives $200 .

Select all the ratio that are equivalent to 8:6.
A. 4:3
B. 6:8
C. 16:12
D. 10:8
E. 7:5
4:3 and 16:12
4 times 2 is 8
3 times two is 6 therefore
4:3 has the same value
same with the second except it is 8 and 6 times 2
Answer: A and C
Step-by-step explanation: If you take the ratio and divide both sides by 2, you get the equivalent ratio 4:3. Then if you take the ratio and multiple both sides by 2, you will get the equivalent ratio 16:12. This means that both A and C are equivalent to the ratio 8:6.

Answer:
21.46 mm^2
Step-by-step explanation:
The area of the square is ...
A = s^2 = (10 mm)^2 = 100 mm^2
The area of the circle is ...
A = πr^2 = π(5 mm)^2 = 25π mm^2 ≈ 78.54 mm^2
Then the shaded area is ...
100 mm^2 -78.54 mm^2 = 21.46 mm^2 . . . shaded area

A professional baseball player earned $1,715,000 from
playing baseball last year.
An autobiography he had written last year sold 300,000
copies at a price of $24 each. He received 10% in
royalties on the book sales.
What was his total salary last year?
$
Answer:
The right answer is actually $2,435,000.00
Step-by-step explanation:
The reason is because you take 300,000 and times that by 24 then you get 7,200,000 then you take that and times it by 0.10 then you get 720,000 then you add that to the 1,715,000 and you get 2,435,000.
300,000 x 24 = 7,200,000
7,200,000 x 0.10 = 720,000
720,000 + 1,715,000 = 2,435,000
So, $2,435,000.00 is your answer.
The total salary last year was $2,435,000 if a professional baseball player earned $1,715,000 from playing baseball last year.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
A professional baseball player earned $1,715,000 from playing baseball last year.
The total earning from autobiography = 300,000x24
= 7,200,000
The royalty amount = 10% of 7,200,000
The royalty amount = 0.10x7,200,000
The royalty amount = 7,200,00
Total salary last year = 1,715,000 + 7,200,00
Total salary last year = $2,435,000
Thus, the total salary last year was $2,435,000 if a professional baseball player earned $1,715,000 from playing baseball last year.

The number which is closest to the addition of two fraction numbers, 1/2 + 1/3 is 0.8.
What is the fraction number?A fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,
[tex]\dfrac{a}{b}[/tex]
Here, (a) is the numerator and (b) is the denominator.
We have to find the addition of two fraction number 1/2 and 1/3. Suppose the value which is closest to 1/2 + 1/3 is n. Thus,
[tex]n=\dfrac{1}{2}+\dfrac{1}{3}\\[/tex]
Cross multiply to find the addition of two numbers,
[tex]n=\dfrac{3+2}{6}\\n=\dfrac{5}{6}\\n=0.833[/tex]
Thus, the number which is closest to the addition of two fraction numbers, 1/2 + 1/3 is 0.8.
