This will equal a 1 out of 25 chance.
You take the number of items you are looking for ( for example, 2 Tomato Cans) Divided by the total items you have (All 10 cans that are a possibility). Then you take your probabilities, and multiply them.

Robert sold 6 more magazine subscriptions the second week than he sold the first week. He sold twice as many the third week as he sold the first. If he sold 94 magazine subscriptions in all, how many did he sell the second week?
Answer:
22
Step-by-step explanation:
let 1st week magazines sold be x
number of magazines sold in 2nd week is 6 more than 1st week that is (x+6)
number of magazines sold in 3rd week is double of 1st week that is 2x
total=94
x+(x+6)+2x=94
x+x+6+2x=94
4x=94-6
4x=88
x=88/4
x=22
Sumaya is using two different strings of Christmas lights to decorate her house.one string flashes every 10 seconds.the other one string flashes every 15 seconds.when Sumaya turns on the lights they flashes at the same time.work out how long it will be before they flash again at the same time.use the LCM to help you work out your answer
Answer: 30 seconds
Step-by-step explanation:
From the question, we are informed that one string flashes every 10 seconds while the other one string flashes every 15 seconds.
The number of minutes that it'll take before they both flash again at the same time will be gotten by calculating the LCM of 10 and 15. This will be:
10 = 10, 20, 30, 40, 50 ...
15 = 15, 30, 45, 60, 75 ....
We can see that the lowest common multiple of 10 and 15 is 30. Therefore, the answer is 30.
They'll both flash again at same time in 30 seconds.
26. The two triangles below are similar. What
is the perimeter of triangle XYZ?
Answer:
24
Step-by-step explanation:
6 ÷ 15 = 0.4
X to Y = 20 × 0.4 = 8
Y to Z = 25 × 0.4 = 10
Perimeter: a + b + c
6 + 8 + 10 = 24

Janice has $2.30 made up of dimes, pennies and quarters. She has as many dimes as pennies and she has 17 coins in all. How many quarters does she have? (PLEASE HELP ME)
Answer:The equation would be 230 = 25y + 10x + 1x or 230 = 25y + 11x
You would then need to solve for x and y, which I forget how to do with 2 variables but since we're working with small numbers what I would do is continuously subtract 25 from 230 until the remainder is divisible by 11.
230 - 25*7 = 55 = 11*5
x = 5
Ok, adding the equation 2x+y = 17 you will now be able to solve for the two variables using a system of equations.
yes, you can come up with an equation. actually, you can come up several equations to generate a system of equations.
your first equation is correct.
(1) 25q + 10d + 1p = 230
now, you're told that the number of dimes equals the number of pennies. that just means, in symbols:
(2) d = p
finally, you're told that you have 17 coins in all, i.e.:
(3) q + d + p = 17
you now have three equations and three unknowns. use (2) to reduce (1) and (3).
(1′) 25q + 11d = 230
(3′) q + 2d = 17
now solve for the three variables.
Answer:
7 quarters
Step-by-step explanation:
We can use the guess method.
17 coins altogether, and as many dimes as pennies.
The number of quarters must be odd. When you subtract an odd number of quarters from 17, you get an even number which will divide by 2 evenly giving you the same number of pennies and dimes.
Start with a guess of 7 quarters.
17 - 7 = 10
7 quarters + 5 pennies + 5 dimes have a value of $2.30
Wow, I got it with the first guess.
Answer: 7 quarters
Find three consecutive even integers such that the sum of the smallest and the largest is 36.
Answer:
Step-by-step explanation:
The consecutive even integers are (2n-2), (2n), and (2n+2), where n is an integer.
(2n-2) + (2n+2) = 36
4n = 36
n = 9
(2n-2) = 16
(2n) = 18
(2n+2) = 20
The value of Melissa's Jeep is $28,000 and is depreciating at a rate of 14% per year. Use an exponential function to find the value of the Jeep after 6 years. Round to the nearest cent. *
Answer:
$12,088
Step-by-step explanation:
Value = $28,000
Rate, r = 14% = 0.14
Time = 6 years
Using an exponential function :
A = Pe^-rt
P = initial value
A = final worth
A = 28000*e^-(0.14*6)
A = 28000 * e^-0.84
A = 28000 * 0.4317105
A = 12087.894
Worth after 6 years = $12,088
Branden and Janna are analyzing the same conditional statement. Branden finds multiple examples that validate the conditional statement. Janna finds one example that satisfies the hypothesis of the conditional statement, but not the conclusion. Which must be true? The conditional statement is true. There are more examples that validate the statement than there are that do not. The conditional statement is true. There is at least one example that validates the statement. The conditional statement is false. There is at least one counterexample for the statement. The conditional statement is false. There must be exactly one example that validates the statement.

World Gym has an initial fee of $100 and $50 per month. Flex Gym has an initial fee of $200 and $25 per month. How many months will it take
until you would pay the same amount to join at both gyms?
a. 4 months
b. 5 months
C. 2 months
d. 6 months
answer:
a. 4 months
step-by-step explanation:
set up an expression for each and put them equal to each otherthis is the way you can use to solve these kinds of problemsbreak down the question into partsm stands for months
world gym = 100 + 50m
flex gym = 200 + 25m
now put them equal to each other to know how many months it will take to pay the same amount to join100 + 50m = 200 + 25m
50m = 100 + 25m
25m = 100
m = 4
this means it will take 4 months to pay the same amount to joinA = (1,5)
C = (1.75, 2.5)

This is More of a Studying Question. How do you remember how to do a certain type of math, I’m going back to school in a month they just decided to make us take state tests again and I’m having major issues Remembering How to do Algebra so I am trying to re-learn half of it in under a month.
Answer:
Step-by-step explanation:
I know this might not be a great answer, but for myself it is much easier to remember math concepts when I apply the concept to real world problems while I am learning. This has two benefits, you will be practicing the concept which reenforces the learning and it automatically tells your brain that the information is valuable in life and that is should remember the idea.

Lori bought some cookies for $2 each and muffins for $3 each. She bought twice as
many muffins as cookies and spent $16. How many cookies did Lori buy?
Answer:
2 cookies
Step-by-step explanation:
let c represent cookies, m represent muffins. set up a system of equations:
2c+3m=16
m=2c
(the top equation shows that cookies are $2 each, and muffins are $3, and that the total cost is $16. the bottom equation shows that Lori bought twice as many muffins as cookies).
then solve the system of equations by substitution, substituting 2c for m in the top equation:
2c+3(2c)=16
2c+6c=16
8c=16
c=2
this means that lori bought 2 cookies.
Answer:
2 cookies
Step-by-step explanation:
let c = no. of cookies
2c = no. of muffins
The cost for c cookies is 2c since each cookie was $2
and the cost of 2c muffins is 3(2c) = 6c since each muffing was $3
The total cost = 2c + 6c = 16
8c = 16
c = 2
So, she bought 2 cookies and 4 muffins

Answer:
21.75 or [tex]21\frac{3}{4}[/tex]
Step-by-step explanation:
You have to convert from a mixed number to a decimal. You can follow the following steps: To do this:
1.) You must divide the fraction's numerator by the denominator.
2.) You must now add the quotient obtained to the part of the Whole number.
you will get:
[tex]{\large\boxed{\fcolorbox{7}{\frac{1}{4}=7+0.25=7.25 }}[/tex]
The scale of the image that maps "Figure a" to "Figure b" is:
[tex]{\large\boxed{\fcolorbox{1:7.25}}[/tex]
3.) You have to multiply by 7.25 the length of the corresponding side of "Figure A" in order to find the value "x."
The final result will be:
[tex]{\large\boxed{\fcolorbox{x=(3)(7.25)}}[/tex]
[tex]{\large\boxed{\fcolorbox{x=21.75}}[/tex]
