Answer:
$31,598.33
Step-by-step explanation:
she worked 4+5=9 days.
due the total average we need the total of sales and divide it by the length of the observation period (9 days).
how much did she sell in total on the first 4 days ?
well, the average times 4 = 32130×4 = $128520
how much did she sell in total during the following 5 days ?
31173×5 = $155865
so, the daily average is
($128520 + $155865) / 9 =$284385 / 9 = $31,598.33

Answer:
h(0) = - 2
Step-by-step explanation:
Substitute x = 0 into h(x) and evaluate , that is
h(0) = 2(0)² - 2 = 2(0) - 2 = 0 - 2 = - 2

If it costs $5.35 per day for a 5 day work week to ride the bus, and a weekly pass is $25, how much could a person save by buying the pass?
Answer:
$1.75
Step-by-step explanation:
basically we are comparing
5 daily passes vs. a weekly pass.
5 daily passes = 5×$5.35 = $26.75
a weekly pass = $25.00
so, the difference is 26.75 - 25 = $1.75

Find the least common multiple of 9 and 15
Answer:
45
Step-by-step explanation:
9:9,18,27,36,45
15:15,30,45
Answer:
45
Step-by-step explanation:
The least common multiple is the smallest number found between the two numbers, in this case 9 and 15, while skip counting from each number. Or the like the multiplication table.
Multiples for 9:
9, 18, 27, 36, 45, 54, 63...
Multiples for 15:
15, 30, 45, 60, 85...
45 is the first and common number that appears in both multiples of 9 and multiples of 15. Therefore, it will be the least common multiple of 9 and 15.

Find the area of the circle.
Use 3.14 for it.
d = 8 cm
A = [?] cm2
A= 7Tr2
Answer:
50.24 cm^2.
Step-by-step explanation:
If d = 8 then r = 4 cm.
Area = 3.14 * r^2
= 3.14 * 4^2
= 50.24 cm^2.

Divide by rationalizing the denominator.
3+5i/10+3i
A. 25+47i/109
B. 60-18i/109
C. 100-30i/109
D. 45+41i/109
Answer:
D
Step-by-step explanation:
Multiply the numerator and denominator by the conjugate of the denominator.
Note that i² = - 1
The conjugate of 10 + 3i is 10 - 3i , then
[tex]\frac{(3+5i)(10-3i)}{(10+3i)(10-3i)}[/tex] ← Expand numerator/denominator using FOIL
= [tex]\frac{30-9i+50i-15i^2}{100-30i+30i-9i^2}[/tex] ← simplify
= [tex]\frac{30+41i+15}{100+9}[/tex]
= [tex]\frac{45+41i}{109}[/tex] → D

Lauren spent $3.26 for lunch on Tuesday. She spent $3.56 on Wednesday and $3.29 on Thursday. Order the prices from greatest to least. Draw a number line to support my the answer
The number line visually shows the order of the prices, with $3.56 on the right (the greatest), followed by $3.29, and then $3.26 on the left (the least).
$3.56 $3.29 $3.26
|------------|------------|
To order the prices from greatest to least, we'll compare the amounts spent on each day:
1. Wednesday: $3.56
2. Thursday: $3.29
3. Tuesday: $3.26
So, in order from greatest to least, the prices are:
$3.56 > $3.29 > $3.26
Now, let's represent this order on a number line:
$3.56 $3.29 $3.26
|------------|------------|
The number line visually shows the order of the prices, with $3.56 on the right (the greatest), followed by $3.29, and then $3.26 on the left (the least).

The length of a rectangle is three times its width. It the perimeter of the rectangle is 96m, find the length and breadth of the rectangle
Let the width, w = x m
So, according to the Question,
The length, l = 3x m
Perimeter of a rectangle = 2 (l + w) m
Perimeter of the rectangle = 96 m
It's equation will be,
2 (3x + x) m = 96 m
or, 4x m = 96/2 m
or, 4x m = 48 m
or, x m = 48/4 m
or, x m = 12 m
Therefore, the width and the length of the rectangle is 12 m and 3(12) m = 36 m respectively.

A bag contains 7 red marbles, 8 blue marbles, and 9 green marbles. What is the
probability of choosing a blue marble when one marble is drawn?
Answer:
The probability of choosing a blue marble is 1/3.
Step-by-step explanation:
Add up all of the marbles.
7+8+9=24.
Next, you get the fraction of the chosen marble type over all marbles. In this case, it's blue, so it's 8/24
Finally, you must simplify the fraction.
1/3 is the simplest form of 8/24.

The expression 146 - 144 is equal to
O 142
1
14 10
Step-by-step explanation:
I am sure you mistyped something here and/or there is something missing.
because 146 - 144 = 2
and nothing in the answer options shows anything like it.
now, if the problem actually said for example
14×6 - 14×4
that could be expressed as
14×(6-4) = 14×2
and that could be the first answer option (also with missing multiplication symbol).
