Answer:
probability of tossing a coin 3 times and getting heads each time is 1/8
Step-by-step explanation:
A coin has 2 sides (heads and tails) therefore you have a 50% chance of getting either heads or tails for each toss. Therefore, the probability of getting heads for 1 toss is 1/2. Now, tossing it 3 times and getting heads each time essentially means you would have to do (1/2)×(1/2)×(1/2) which would give you 1/8 as the probability of tossing a coin 3 times and getting heads each time.
Ivan read a total of 15 books over 5 months. After belonging to the book club for 8 months, how many books will Ivan have read in all? Solve using unit rates.
Answer:
24 books.
Step-by-step explanation:
Because 15 books divide 5 months would be 3 books so each month is 3 books so 3 books times 3 more months would be 9 books and then you add 15 to 9 and you get 24.

Answer:
he started out with 87 cards
Step-by-step explanation: 46 x 2 = 92 - 5 = 87
Answer:
87
Step-by-step explanation:
If the dog ate half of the collection, he would have 92 but the question asks how many he started with so you would subtract 92-5 to get 87. Hope this helped.

show that (-2, 1), (2, -2) and (5,- 2) are the vertics of the right triangle
Step-by-step explanation:
A= (-2,1)
B= (2,-2)
C=(5,2)
slope = y1 - y2/ x1- x2
slope of
AB = -2-1/2-(-2)
= -3/4
BC= 2-(-2)/5-2
= 4/3
AC = -2-1/5-2
= -3/3
=-1
if ABC is a right triangle then AB should be perpendicular to BC
AB x BC = -1
LHS
=-3/4 x 4/3
=-1
= RHS
hence triangle ABC is a right triangle

Don’t do 7. And nine it been done already
Answer:
Step-by-step explanation:
8. subtract 78 from both sides so you get r=-93
10. divide both sides by 8 so you get j=12
11. divide both sides by -13 so its z=3
12.divide both sides by 15 so its m=-12
13. divide both sides by 27 to get r=9
14. multiply both sides by 9 (9/1) to get y=-72
15. multiply both sides by 12 to get -j=-96 then divide it by - to get j=96
16. multiply it by 15/1 so its a by itself and then use cross multiplication to simplify it so 4/5 x 15/1 so 15 becomes 3 and 5 becomes 1 so its 4x3 which is 12 so a=12
17. g=6

I am thinking of a number when you divided my number by 5 and add 10 you get 20
Answer:
the answer is 50.000000000000
Answer:
My number is 50.
Step-by-step explanation:
My number(50) will be divided by 5. It will give me 10. Then we take that 10 and add 10. It will give 20.50 divided by 5 = 1010 + 10 = 20Mason makes homemade pizza sauce. The recipe calls for 5 ounces of tomato sauce for every

Question
C.
A student's pay of $22 an hour is $7 more than twice the amount the student earns
per hour at an internship. Enter and solve an equation to find the hourly pay of the
internship.
= 2x +
The internship pays $
an hour.
Answer:
The internship pays $7.5 an hour.
Step-by-step explanation:
From the information given, the equation would indicate that the amount the student earns per hour at the intership for two plus seven would be equal to 22:
2x+7=22
Now, you can solve for x:
2x=22-7
2x=15
x=15/2
x=7.5
According to this, the answer is that the internship pays $7.5 an hour.
Andrew used this table to describe several numbers. What error did he make? A.√36 should also be an integer. B. 0.345 should also be an integer. C. −√25 should also be a whole number. D. 0.345 should be a whole number.
Answer:
A rational number is an integer that either doesn't have a decimal or has a decimal that either repeats or terminates (ends). Basically, if these square roots come out to be an integer, they're rational.
The first one comes out to be 42.6028168083, so obviously not rational.
The second one comes out to be 55, so it is rational.
Consider the provided numbers.
√1,815 and √3,025
The value of √1,815 = 48.60281680.....
The value of √3,025 = 55
Now consider the definition of rational and irrational number.
Rational number: A number is said to be rational, if it is in the form of p/q. Where p and q are integer and denominator is not equal to 0.
Irrational number: A number is irrational if it cannot be expressed be expressed by dividing two integers. The decimal expansion of Irrational numbers are neither terminate nor periodic.
The number √1,815 is an irrational number as the decimal expansion of numbers is neither terminate nor periodic.
The number √3,025 is a rational number as it is in the form of p/q.
three times the absolute value of the sum of a number and 6
Answer:
[tex]3|x + 6|[/tex]
Step-by-step explanation:
Required
Get the equivalent of the given statement
Let the number be represented by x
So:
Sum of a number and 6 will be:
[tex]Sum =x + 6[/tex]
The absolute value will be:
[tex]Absolute = |x + 6|[/tex]
Three times this will be:
[tex]Product = 3 * |x + 6|[/tex]
This can be further represented as:
[tex]Product = 3 |x + 6|[/tex]
Hence, the equivalent of the given statement is [tex]3|x + 6|[/tex]
There are 8 more males in Sara's class than females. If 3/5 of the students are male, how many students are in Sara's class?
Answer:
40 students
Step-by-step explanation:
Let
Total students in Sara's class = x
Number of males = 3/5x
Number of females = Total students - male students
= x - 3/5x
= 5x-3x/5
= 2/5x
Number of females = 2/5x
There are 8 more males in Sara's class than females.
Therefore,
Males = 2/5x + 8
Total number of students = number of males + number of females
x = 2/5x + 8 + 2/5x
x = 2x+2x/5 + 8
x = 4/5x + 8
x - 4/5x = 8
5x-4x/5 = 8
1/5x = 8
Divide both sides by 1/5
x = 8 ÷ 1/5
= 8 × 5/1
x = 40
Therefore, there are 40 students in Sara's class
Check
Males = 3/5x
= 3/5×40
= 3×8
= 24
Females = 2/3x
= 2/5 × 40
= 2 × 8
= 16
Therefore, there are 8 more males than females
