Fiona earns $15 for each lawn she mows. Which inequality can be used to find out how many lawns she must mow to earn at least $135?
Final answer:
Fiona needs to mow at least 9 lawns to earn at least $135, represented by the inequality 15L ≥ 135, where L is the number of lawns mowed.
Explanation:
To determine how many lawns Fiona must mow to earn at least $135, we can set up an inequality. Fiona earns $15 for each lawn she mows, therefore if we let L represent the number of lawns mowed, then Fiona's earnings can be represented by 15L. She needs to earn at least $135, so we can write the inequality as 15L ≥ 135. To find L, we divide both sides of the inequality by 15, which gives us L ≥ 9. Therefore, Fiona must mow at least 9 lawns to earn at least $135.

There are 52 blades of grass in 2 in2 of lawn. There are 580 blades of grass in 8 in2 of the same lawn. Which equation models the y blades of grass found in x in2 of lawn?
The equation that models the relationship between the number of blades of grass (y) and the area of lawn (x) is y=88x−124. This equation represents the rate of 88 blades per square inch with an initial count of 52 blades.
To find the equation that models the relationship between the number of blades of grass (y) and the area of lawn (x), we can use the given information to form a linear equation.
Step 1: Determine the rate of change. Subtract the initial number of blades from the final number and divide by the change in area: (580 - 52) / (8 - 2) = 528 / 6 = 88 blades per square inch.
Step 2: Write the equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
Step 3: Plug in the slope (m = 88) and one point (x = 2, y = 52) to find the y-intercept:
52 = 88(2) + b
52 = 176 + b
b = -124
Step 4: Write the equation:
y = 88x - 124

Sandy spun a spinner with 5 equal parts labeled 1-5. What is the probability she will Not spin a 4
The probability that she will not spin a 4 will be 0.80 or 4/5.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
Sandy spun a spinner with 5 equal parts labeled 1-5. Then the total number of events will be given as,
Total events = 5 {1, 2, 3, 4, 5}
Then the favorable events are given as,
Favorable events = 4 {1, 2, 3, 5}
Then the probability is given as,
P = 4 / 5
P = 0.80
The probability that she will not spin a 4 will be 0.80 or 4/5.

Final answer:
The probability that Sandy will not spin a 4 on a spinner with 5 equal parts is 4/5 or 80%. There are 4 favorable outcomes and 5 possible outcomes in total.
Explanation:
The question asks for the probability that Sandy will not spin a 4 on a spinner that's divided into 5 equal parts, each labeled with the numbers 1-5. Since there are 5 outcomes and only one of them is the one we want to avoid, that leaves us with 4 favorable outcomes (spinning a 1, 2, 3, or 5). The probability of not spinning a 4 is therefore the number of favorable outcomes (not spinning a 4) divided by the total number of possible outcomes (spinning any number from 1 to 5).
To calculate this, we divide the favorable outcomes by the total number of outcomes. This gives us a probability of 4/5, or 80%. The calculation is as follows:
Number of favorable outcomes: 4 (spinning a 1, 2, 3, or 5)Total number of outcomes: 5 (spinning any number from 1 to 5)Therefore, P(not spinning a 4) = 4 favorable outcomes / 5 total outcomes = 4/5 or 0.8, which means there is an 80% chance that Sandy will not spin a 4.
A savings account was opened with an initial deposit and never touched again. An account that does not meet the minimum balance requirement is charged a service fee.
Assuming the account was open with an initial deposit below the minimum amount, the current account balance, B, is equal to the product of the initial deposit, I, and the quantity of the difference of 1 and the monthly service fee, f, raised to the power of n, the number of months since the account was open.
If an initial deposit of $2,713.00 is made to the account with a monthly service fee of 5%, what will be the value of B after 13 months? Round to the nearest cent.
To find the current balance B after 13 months with an initial deposit of $2,713.00 and a 5% monthly service fee, you multiply the initial deposit by 0.95 to the power of 13, resulting in a balance of approximately $1,392.64.
Explanation:The student's question involves using a given mathematical formula to find the current balance of a savings account affected by a monthly service fee. The formula provided states that the current balance B is equal to the initial deposit I times the quantity (1 - monthly service fee f) raised to the power of the number of months n. To calculate the current balance after 13 months, given an initial deposit of $2,713.00 and a monthly service fee of 5%, you'd perform the following calculation:
Convert the percentage fee to a decimal: 5% = 0.05.Subtract the service fee from 1: 1 - 0.05 = 0.95.Raise the difference to the power of the number of months: 0.9513.Multiply the result by the initial deposit: $2,713.00 × 0.9513.Using a calculator, this gives:
B = $2,713.00 × (0.9513) ≈ $2,713.00 × 0.5133421 ≈ $1,392.64
Rounded to the nearest cent, the value of B after 13 months is $1,392.64.
What is the sixth term in the binomial expression (5y+3)^10
Answer : The sixth term in the binomial expression is, [tex]^{10}C_5a^{5}b^{5}[/tex]
Step-by-step explanation :
The general formula to calculate the term of binomial expression is:
[tex]T_(r+1)=^nC_ra^{(n-r)}b^r[/tex]
where,
(r+1) = number of term
As we are given the binomial expression :
[tex](5y+3)^{10}[/tex]
For sixth term :
a = 5y
b = 3
n = 10
As, r + 1 = 6
So, r = 6 - 1
r = 5
Now put all the given values in the above formula, we get:
[tex]T_(r+1)=^nC_ra^{(n-r)}b^r[/tex]
[tex]T_(5)=^{10}C_5a^{10-5}b^5[/tex]
[tex]T_(5)=^{10}C_5a^{5}b^{5}[/tex]
Thus, the sixth term in the binomial expression is, [tex]^{10}C_5a^{5}b^{5}[/tex]
4) A sales associate in a department store earns a commission on each suit and each pair of shoes sold. One week, she earned $47 in commission for selling 3 suits and a pair of shoes. The next week, she earned $107 in commission for selling 7 suits and 2 pairs of shoes.
a) Write a system of equations to represent the situation. Explain what your x and y will represent.
b) Solve the system of equations.
c) How much commission does she earn for selling each suit and each pair of shoes?
The sales associate earns a commission of $13 for each suit sold and $8 for each pair of shoes sold, found by solving the system of equations representing her commission earnings for two different weeks.
To represent the sales associate's commission earnings, we will use two variables: let x be the commission for each suit sold, and y be the commission for each pair of shoes sold.
(a) System of Equations:
The first week's commission can be represented by the equation 3x + y = 47. The second week's commission can be written as 7x + 2y = 107.
(b) Solving the System:
Multiply the first equation by 2 to get 6x + 2y = 94.Subtract the first modified equation from the second week's equation: (7x + 2y) - (6x + 2y) = 107 - 94.This simplifies to x = 13, meaning the commission for each suit is $13.Substitute x = 13 into the first equation: 3(13) + y = 47.Solve for y: 39 + y = 47, so y = 8.(c) The commission for each pair of shoes is $8.

Horace need to buys 2.5 pounds of blueberries
Horace buys 2/4 pounds of blueberries48 ounce of blueberries needed for a pieTo determine how many pounds of blueberries that Horace need to buy, we have to convert ounces because this mathematical question is related to unit conversion.Further Explanation1 pounds = 16 ounces, therefore,
3 pounds = 48 ounces (we multiply 16 and 3 = 48)
To find how many pounds he need to by = 3 ounces – [tex]\frac{2}{4}[/tex]
= 3 – [tex]\frac{2}{4}[/tex]
= [tex]\frac{3}{1}[/tex] – [tex]\frac{2}{4}[/tex] (4 is the smallest number can divide both denominator) therefore, we have
