Determine which is the better buy.
9 straps for $10.25 or 30 straps for $66.00
Answer:
9 straps for $10.25
Step-by-step explanation:
Price rate
9 straps for $10.25 = 10.25/9 = $1.14 per strap30 straps for $66 = 66/30 = $2.20 per strapBetter buy
9 straps for $10.25Less cost per strapbetter buyAnswer:
9 straps
Step-by-step explanation:
If you're selling 30 straps for $66 then you get a 2.2 per each
But 9 straps for $10.25 will get 1.139
So, the value that's smaller which is 9 straps for $1.139 is a better buy
Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.
Growth factor Levels
Lighting Low, Medium, High, Very high
Age month, months, months, months, months
Temperature , , ,
She wants to find the number of ways of combining one level from each of the growth factors. How many ways are there?
Answer:
there are so many ways
Step-by-step explanation:
such as observing day by day and checking its height with a scale everyday etc
The number of ways of combining different growth factors to form a level is 80.
What is Permutation?The act of organizing all the components of a set into some sequence or order is known as permutation. Permuting, in other words, is the act of reordering the components of a set that has previously been sorted.
A permutation is the selection of r items from a collection of n items without replacement, with the order of the items being significant.
nPr = (n!) / (n-r)!
What is a Combination?The combination is a method of picking elements from a collection in which the order of selection is irrelevant (unlike permutations).
A combination is a selection of r items from a collection of n items with no replacements and no regard for order.
nCr = (n!)/{(r!)((n-r)!)}
How do we solve the given question?We are given that Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.
Growth factor Levels
Lighting: Low, Medium, High, Very high.
Age: 1 month, 2 months, 3 months, 4 months, 5 months.
Temperature: 20°, 22°, 24°, 26°.
We are asked to find the number of ways in which she can combine different levels to form one level.
We first check the number of combinations for each factor and then multiply them all to get the total number of ways possible.
Lighting: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 = 4).
Age: 5 (∵ All the 5 levels are possible, so the combinations are 5P1 = 5).
Temperature: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 =4).
∴ Total number of ways of combining different growth factors to form a level = 4*5*4 = 80
∴ The number of ways of combining different growth factors to form a level is 80.

Land developers are dividing a property into several sections to develop a new neighborhood, as shown below.
• Find the area, in square blocks, of the mall section of the property. Show all your work.
• Find the area, in square blocks, of the park section of the property. Show all your work.
• Find the total area, in square blocks, of the sections with homes. Show all your work.
• If the developers paid $500.00 per square block, how much did they pay for all the property being developed? Explain your answer.
Answer:
$97500.00
Step-by-step explanation:
the homes of the homes facing south is 10 times (7 plus 3) = 100 blocks
the area of the east facing homes is 8 times 10= 80 blocks
and the area of the trapezoid is 5 plus 3 times 3 = 15 blocks
so 100+80+15= 195 square blocks
195 times 500 = $97500.00

Can someone help me with this math equation? Can you explain how to work it out also?
Answer: 50
Explanation:What we know:The numerator is 6The denominator is equal to (3*5)^(-2)In fraction-style equations, the numerators are divided by denominatorsNegative exponents are equal to (base)^|power|, and then reversing the products place in the fraction
How to solve:
By utilizing our knowledge of the PEMDAS solving method, negative powers, and fraction-style equations, this problem can be solved with a simple step-by-step procedure
Process:ExponentSet up equation 6 / [3 * 5^(-2)]
Rewrite power 6 / [3 * (5 * 5)]
Simplify power 6 / [3 * (25)]
Invert power 6(25) / 3
SimplifyingSet up equation 6(25) / 3
Simplify 150 / 3
Simplify (using common denominator) 50 / 1
Rewrite in simplest form =50

a cast member is selling balloons on main street. he has 4 princess balloon, 5 blue mickey balloons and 1 red mickey balloon. he sells 1 balloon and then another (no replacing). find the probability of selling one blue balloon followed by another blue balloon.
Answer:
hee-hee!
Step-by-step explanation:
We first have to find how many possible outcomes there are.
We find that out by seeing how many types of balloons are in total.
4 + 5 + 1 = 10
There are 10 possible outcomes.
We then see how many favorable outcomes there are.
There are 5 blue mickey balloons.
That means 5/10 or 1/2.
Then we subtract 1/10 from 5/10.
5/10 - 1/10 = 4/9
We lower the denominator by 1 because the total possible outcomes are also lowered by one.
The probability of the cast member selling another blue balloon after selling the first one is 4/9.
hope this helps :)
