Answer:
C) $1412.79; D) monthly salary of $2995; B) $18.94; C) $573.75
Step-by-step explanation:
Getting paid semimonthly means there will be two paychecks a month. There are 12 months in the year, so this is 24 checks per year. To find the gross pay on each check, divide the salary by 24:
33907/24 = 1412.79
There are 52 weeks per year. This means a weekly salary of 781 would be an annual income of 781(52) = 40,612.
A biweekly salary means getting paid every two weeks. This means there will be 52/2 = 26 paychecks per year; this gives an annual income of 26(1430) = 37,180.
Semimonthly pay means there will be 24 paychecks per year; this gives us an annual income of 24(1550) = 37,200
There are 12 months in the year; this gives us an annual salary of 12(2995) = 35,940. This is the smallest amount in our given choices.
25% = 25/100 = 0.25; this makes the tip 0.25(75.77) = 18.9425 ≈ 18.94.
11.25 per hour for 35 hours is 11.25(35) = 393.75. 4.5% commission is 4.5/100(4000) = 0.045(4000) = 180. Together this gives us
393.75+180 = 573.75

Lisa has $7.80 to spend on some tomatoes and a loaf of bread. Tomatoes cost $1.20 per pound, and a loaf of bread costs $1.80. The inequality 1.20x + 1.80 ≤ 7.80 models this situation, where x is the number of pounds of tomatoes. Solve the inequality. How many pounds of tomatoes can Lisa buy? A. x ≤ 8; Lisa can buy 8 pounds or less of tomatoes. B. x ≥ 5; Lisa can buy 5 pounds or more of tomatoes. C. x ≤ 5; Lisa can buy 5 pounds or less of tomatoes. D. x ≥ 8; Lisa can buy 8 pounds or more of tomatoes.
Answer:
C. [tex]x\leq 5[/tex]; Lisa can buy 5 pounds or less of tomatoes.
Step-by-step explanation:
We have been given an inequality [tex]1.20x+1.80\leq 7.80[/tex], where x is the number of pounds of tomatoes. The inequality represents amount spend by Lisa on tomatoes and loaf. We are asked to find number of pounds that Lisa can buy.
First of all, we will subtract 1.80 from both sides of our inequality.
[tex]1.20x+1.80-1.80\leq 7.80-1.80[/tex]
[tex]1.20x\leq 6.00[/tex]
Now, we will divide both sides of our inequality by 1.20.
[tex]\frac{1.20x}{1.20}\leq \frac{6.00}{1.20}[/tex]
[tex]x\leq 5[/tex]
Therefore, Lisa can buy 5 pounds or less of tomatoes and option C is the correct choice.

The interior angles of a regular polygon each measure 165 degrees. how many sides does the polygon have
If a regular polygon has interior angles each measuring 165 degrees, the polygon has 24 sides. This is calculated by using the formula to find the number of sides in a regular polygon, given the angle size.
Explanation:To find out how many sides a regular polygon has, based on the size of its interior angles, you can use the formula to calculate the sum of the interior angles of a polygon:
n
= 180(
n
- 2), where
n
is the number of sides.
However, this formula gives the sum of the interior angles as a whole. Since, in a regular polygon, all angles are equal, you can then divide this sum by the known size of each angle.
So the specific formula to calculate the number of sides of a regular polygon, given the angle size, is:
n
= 360 / (180 -
angle size
).
In this case, you can substitute the angle size of 165 degrees into this formula:
n
= 360 / (180 - 165) = 360 / 15 = 24.
So a regular polygon with interior angles each measuring 165 degrees has 24 sides.

B is between A and C, D is between B And C, and C is between B and E. AE = 28cm, BC =10cm. AB = DB = DC. what is the length of CE ?
Final answer:
By using the given lengths of AE and BC, along with the equality of AB, DB, and DC, we can solve for CE to be 14.67cm.
Explanation:
The lengths of AE, BC, AB, DB, and DC are given or can be determined with the information provided. Since AB = DB = DC and BC is given as 10 cm, we can deduce that AB + BC + CE = AE. Given AE is 28cm and BC is 10cm, we can find the length of AB by realizing that AB + AB + AB (which is AB + DB + DC) is the same as BC or 10cm. This makes each section AB, DB, and DC equal to 10cm / 3.
With AB, DB, and DC all being equal to 10cm / 3, and knowing AE is 28cm, we can then calculate the length of CE:
AE = AB + BE (and BE = BC + CE)
28cm = (10cm/3) + (10cm + CE)
To find CE, rearrange the equation:
CE = 28cm - 10cm - (10cm/3)
CE = 28cm - 10cm - 3.33cm
CE = 18cm - 3.33cm
CE = 14.67cm
To solve for the length of CE in a line segment configuration, we calculate CE = AE - BC - DC after determining the lengths of AB, BC, and DC. The solution reveals that CE is 9cm.
Explanation:The student has a geometry problem, which involves calculating the length of segment CE on a line segment AE. We know that AE = 28cm and BC = 10cm, with AB, DB, and DC being equal in lengths.
Since B is between A and C, and D is between B and C, and C is between B and E, we can write the entire length AE as AB + BC + CE. Because AB = DB = DC, we can substitute DB and DC for AB in the sums to get 2(DB) + BC = 28cm.
We are given that BC = 10cm, so we can set up an equation: 2(DB) + 10cm = 28cm. Solving for DB, we find that DB = 9cm. Since DC is equal to DB, DC is also 9cm. CE can be found by subtracting BC and DC from the total length of AE: CE = AE - BC - DC, so CE = 28cm - 10cm - 9cm, resulting in CE = 9cm.

Almonds cost $15.50 for 6 pounds. Find the unit rate. Round to the nearest cent if necessary.
The unit rate for almonds is approximately $2.58 per pound.
To find the unit rate, we divide the total cost by the total quantity.
In this case, the total cost is $15.50 and the total quantity is 6 pounds.
So, the unit rate is:
[tex]\[ \text{Unit rate} = \frac{\text{Total cost}}{\text{Total quantity}} \][/tex]
[tex]\[ \text{Unit rate} = \frac{15.50}{6} \][/tex]
[tex]\[ \text{Unit rate} \approx \$2.58 \][/tex]
Rounding to the nearest cent, the unit rate is approximately $2.58 per pound.
Jackson purchased some power tools totaling $1,543 using a six month deferred payment plan with an interest rate of 23.76%. He did not make any payments during the deferment period. What will the total cost of the power tools set be if he must pay off the power tools within two years after the deferment period?
$1,543.00
$1,735.63
$2,197.44
$2,746.80
The total cost of the power tools set if Jackson must pay off the tools within two years after the deferment period is $2,644.82.
To find the total cost of the power tools set after the deferred payment period, we need to consider both the initial cost of the tools and the interest accrued during the deferment period and the subsequent payment period.
First, let's calculate the interest accrued during the deferment period:
Interest = Principal × Rate × Time
Interest = $1,543 × 23.76% × (6/12) (since the deferment period is 6 months)
Interest = $1,543 × 0.2376 × 0.5
Interest = $183.78
Now, add this interest to the initial cost of the power tools:
Total cost after deferment = Initial cost + Interest
Total cost after deferment = $1,543 + $183.78
Total cost after deferment = $1,726.78
Next, we need to calculate the total amount Jackson must pay off within two years after the deferment period. This includes the principal amount and the interest accrued during the payment period. We'll use the formula for calculating the total payment for a loan with compound interest:
[tex]\[A = P(1 + r/n)^{nt}\][/tex]
Where:
A = Total amount to be paid
P = Principal amount (initial cost after deferment)
r = Annual interest rate (as a decimal)
n = Number of times interest is compounded per year
t = Time in years
In this case, we'll compound interest annually, so (n = 1), and (t = 2) years.
[tex]\[A = $1,726.78(1 + 0.2376/1)^{1*2}\][/tex]
[tex]\[A = $1,726.78(1 + 0.2376)^2\][/tex]
[tex]\[A = $1,726.78(1.2376)^2\][/tex]
[tex]\[A = $2,644.82\][/tex]
So, the total cost of the power tools set if Jackson must pay off the tools within two years after the deferment period is $2,644.82.
