Jordan's account balance at the end of the month would be $143.85.
What is the basic arithmetic operations?
The four basic mathematical operations are Addition, subtraction, multiplication, and division.
To determine Jordan's account balance at the end of the month, we need to add up the deposits and withdrawals to the initial balance.
Initial balance: $92.66
Deposits: $7.72 + $70.42 + $107.46 = $185.60 (sum of positive amounts)
Withdrawals: -$84.26 + (-$50.15) = -$134.41 (sum of negative amounts)
To calculate the account balance at the end of the month, we can add the deposits and withdrawals to the initial balance:
Account balance at the end of the month = Initial balance + Deposits - Withdrawals
= $92.66 + $185.60 - $134.41
= $143.85
Hence, Jordan's account balance at the end of the month would be $143.85.

Jeannie designs jewelry. The figure shows a
pendant on a necklace Jeannie is making. It is
composed of three individual beads.
The larger triangular bead cost $1.52. The
rectangular bead costs $0.42, and the smaller
triangular bead costs $0.92.
What is the cost per square millimeter of the
pendant? Round your answer to the nearest
hundredth.
Answer: ≅ $0.02
Step-by-step explanation:
First, lets find the area of the large triangle
0.5 x 14 x 11 = 77 mm^2
Next lets find the area of the middle rectangle:
4 x 14 = 56 mm^2
Last lets find the area of the small triange:
0.5 x 14 x 3 = 21 mm^2
So the total area is: 77 + 56 + 21 = 154 mm^2
the total cost is given to be: 1.52 + 0.42 + 0.92 = $2.86
dividing the cost by the area to find the cost/mm:
2.86/154 ≅ $0.02

A subscription to a live streaming program normally costs $29 but is on sale for 25% off. An 8% tax is added at checkout. What is the total cost?
$7.25
$21.75
$23.49
$39.15
A subscription to a live streaming program normally costs $29 but is on sale for 25% off. An 8% tax is added at checkout then the total cost is $23.49.
To calculate the total cost, first, we find the discounted price of the subscription. A 25% discount on $29 is calculated by multiplying $29 by 0.25 (25% as a decimal), which gives us a discount of $7.25. Subtracting the discount from the original price, we get the discounted price of $29 - $7.25 = $21.75.
Next, we need to add the 8% tax to the discounted price. To calculate the tax amount, we multiply $21.75 by 0.08 (8% as a decimal), which gives us $1.74. Adding this tax amount to the discounted price, we get the total cost as $21.75 + $1.74 = $23.49.
Step 1: Calculate the discount amount:
Discount = 25% of $29
Discount = 0.25 * $29
Discount = $7.25
Step 2: Find the discounted price:
Discounted Price = Original Price - Discount
Discounted Price = $29 - $7.25
Discounted Price = $21.75
Step 3: Calculate the tax amount:
Tax Amount = 8% of Discounted Price
Tax Amount = 0.08 * $21.75
Tax Amount = $1.74
Step 4: Calculate the total cost:
Total Cost = Discounted Price + Tax Amount
Total Cost = $21.75 + $1.74
Total Cost = $23.49
So, the total cost after applying the 25% discount and adding an 8% tax at checkout is $23.49.
- Discount = 0.25 * $29 = $7.25
- Discounted Price = $29 - $7.25 = $21.75
- Tax Amount = 0.08 * $21.75 = $1.74
- Total Cost = $21.75 + $1.74 = $23.49

Explain by using an example why you need to multiply when converting from a larger unit to a smaller unit
Multiplying is necessary because each larger unit contains a certain number of the smaller units and we need to account for that conversion factor.
Why is multiplication necessary with examples?For example, when converting from meters to centimeters where we know that 1 meter is equal to 100 centimeters.
To convert 3 meters to centimeters, we need to multiply by the conversion factor of 100 which gives us:
= 3 meters * 100 centimeters/meter
= 300 centimeters
So, without the multiplication, we would not account for the fact that each meter contains 100 centimeters. This principle applies to all conversions from larger units to smaller units and it is important to remember to ensure accurate conversions.

VZ is 92.5. WY is the midsegment of AVXZ, it means that WY is parallel to AX and its length is half the length of AX.
what is midsegment ?
A midsegment of a triangle is a line segment connecting the midpoints of two sides of the triangle. It is also known as a midline. The midsegment of a triangle is parallel to the third side of the triangle, and its length is half the length of the third side.
In the given question,
Since WY is the midsegment of AVXZ, it means that WY is parallel to AX and its length is half the length of AX.
Let's call the length of AX as L. Then, we have:
WY = 11t = 1/2 L
Multiplying both sides by 2, we get:
22t = L
Now, we can use this information to find VZ. Since WY is also parallel to VZ, we have:
WV = VZ
Substituting WV = L/2 and VZ = 5t + 51, we get:
L/2 = 5t + 51
Substituting L = 22t, we get:
22t/2 = 5t + 51
11t = 5t + 51
6t = 51
t = 8.5
Substituting t = 8.5 in the equation for VZ, we get:
VZ = 5t + 51 = 5(8.5) + 51 = 92.5
Therefore, VZ is 92.5.

The graph of the linear equation y = (1/2)*x + 3 can be seen in the image at the end.
How to graph the linear equation?Here we want to graph the linear equation:
y = (1/2)*x + 3
To graph it we need to find a few points on the line, graph them on a coordinate axis and then draw a line that connects them.
The first point that we can use is the y-intercept, it is what we get when we evaluate in x = 0.
y = (1/2)*0 + 3
The point is (0, 3)
Then we can get other points by evaluating in different values of x, for example, if x = 2
y = (1/2)*2 + 3 = 1+ 3 =4
If x = 4
y = (1/2)*4 + 3 = 2 + 3 = 5

The standard deviation for the given distribution is 8.739 using either the direct method or the shortcut method.
How to find the standard deviation?Standard deviation is defined as a measure of how spread out numbers are. It is also referred to as the square root of the Variance, and then the Variance is the average of the squared differences from the Mean.
To calculate the standard deviation for the given distribution, we will utilize either the direct method or the shortcut method.
Direct method:
Calculate the mean wage (F) for the distribution:
Mean = (20 + 22 + 27 + 30 + 31 + 32 + 35 + 45 + 40 + 48)/10
Mean = 34
Calculate the differences between each wage and the mean wage:
20 - 34 = -14
22 - 34 = -12
27 - 34 = -7
30 - 34 = -4
31 - 34 = -3
32 - 34 = -2
35 - 34 = 1
45 - 34 = 11
40 - 34 = 6
48 - 34 = 14
Square each of the differences:
(-14)² = 196
(-12)² = 144
(-7)² = 49
(-4)² = 16
(-3)² = 9
(-2)² = 4
1² = 1
11² = 121
6² = 36
14² = 196
Add up the squared differences: 196 + 144 + 49 + 16 + 9 + 4 + 1 + 121 + 36 + 196 = 756
Divide the sum of the squared differences by the number of workers: 756/10 = 75.6
Take the square root of the result to get the standard deviation:
√75.6 = 8.739
Shortcut method:
The mean wage (F) for the distribution:
(20 + 22 + 27 + 30 + 31 + 32 + 35 + 45 + 40 + 48)/10 = 34
The sum of the squares of the differences between each wage and the mean wage:
(20 - 34)² + (22 - 34)² + (27 - 34)² + (30 - 34)² + (31 - 34)² + (32 - 34)² + (35 - 34)² + (45 - 34)² + (40 - 34)² + (48 - 34)² = 756
Divide the sum by the number of workers: 756/10 = 75.6
Take the square root of the result to get the standard deviation:
Standard deviation = √75.6 = 8.739

approximation for pi.
a. 1.254 square meters
b. 312 square meters
c. 2, 822 square meters
d. 314 square meters
Answer:
(a) 1.254 square metersStep-by-step explanation:
We are given a figure, consisting of a right triangle with a circle cut out of it.
To Calculate : area of the shaded region below,
First Let's find the Area of the right triangle:
Area(triangle) = 1/2 × Base × Height
= 1/2 × 56 × 56
= 1/2 × 3136
= 3136/2
= 1568 m².
Now, We are diameter of the circle = 20 m
Radius of the circle = 20/2 = 10 m
Area of circle = πr²Acc. to question we have to use 3.14 as an
approximation for pi.
Area (circle) = 3.14 × 10 × 10
Area (circle) = 3.14 × 100
Area (circle) = 314 m²
Area of shaded region = Area of triangle - Area of circle =
= 1568 m² - 314 m²
= 1.254 square meters
Therefore, The approximate area of the shaded region is 1.254 square meters.

A waitress sold 11 ribeye steak dinners and 14 grilled salmon dinners, totaling $551.11 on a particular day. Another day she sold 15 ribeye steak dinners and 7 grilled salmon dinners, totaling $581.47. How much did each type of dinner cost?
Answer:
A ribeye steak dinner costs $32.23 and a grilled salmon dinner costs $14.04.
Step-by-step explanation:
Let's use variables to represent the cost of each dinner. Let's say that the cost of a ribeye steak dinner is "r" and the cost of a grilled salmon dinner is "s".
From the first day's sales, we know:
11r + 14s = 551.11From the second day's sales, we know:
15r + 7s = 581.47We now have two equations with two variables, which we can solve using elimination or substitution.
Let's use elimination. If we multiply the first equation by 15 and the second equation by 11, we can eliminate the "r" variable:
165r + 210s = 8266.65165r + 77s = 6396.17Subtracting the second equation from the first, we get:
133s = 1870.48Dividing both sides by 133, we get:
s = 14.04So a grilled salmon dinner costs $14.04.
We can substitute this value back into one of the original equations to solve for "r". Let's use the first equation:
11r + 14(14.04) = 551.1111r + 196.56 = 551.1111r = 354.55r = 32.23So a ribeye steak dinner costs $32.23.
Therefore, a ribeye steak dinner costs $32.23 and a grilled salmon dinner costs $14.04.
