Gabriella went to Tiers of Joy Bakery to buy her mom’s birthday cake. The cake was $25.52, which left Gabriella with $24.48 to spend on her mom’s present. Let a be the amount of money Gabriella had before buying the cake. Write and solve an equation to find a.
Answer: $50
Step-by-step explanation:
Let's denote the amount of money Gabriella had before buying the cake as "a". Then we can write an equation to find "a":
a - $25.52 = $24.48
Adding $25.52 to both sides:
a = $25.52 + $24.48
So,
a = $50
Therefore, Gabriella had $50 before buying the cake.

Each side of the base of a square pyramid measures 10 inches. The height of each lateral face of the pyramid is also 10 inches.
What is the surface area of the pyramid?
Enter your answer in the box.
in²
The surface area of the pyramid that has these measures is given as 300 inches square
How to solve for the surface area of the pyramidThe surface area of a square pyramid is the sum of the area of the base and the areas of the lateral faces.
The area of the base of the square pyramid is given by the formula for the area of a square:
A = s^2, where s is the length of one side of the square.
In this case, each side of the base measures 10 inches, so the area of the base is:
A = 10^2 = 100 square inches.
The lateral faces of the pyramid are triangles, and the surface area of each lateral face can be found using the formula:
A = (1/2)bh, where b is the length of the base and h is the height.
In this case, the height of each lateral face is 10 inches, and the base is a side of the square base, which measures 10 inches.
So the surface area of each lateral face is:
A = (1/2)(10)(10) = 50 square inches.
Since there are 4 lateral faces on a square pyramid, the total surface area of the lateral faces is 4 * 50 = 200 square inches.
Finally, the surface area of the pyramid is the sum of the surface area of the base and the lateral faces:
A = 100 + 200 = 300 square inches.

The equations that represent each line are, respectively:
y = - 3 · x + 5 y = x - 4 y = 2 · x - 1 y = (4 / 5) · x - 4How to determine the equations of the line
According to Euclidean geometry, we can generate any line from two distinct points on a plane. Herein we find two tables and two Cartesian representations of the lines, of which we must construct the corresponding line equations, whose definition is shown below:
y = m · x + b
Where:
m - Slopeb - Interceptx - Independent variable.y - Dependent variable.The slope can be found by secant line formula:
m = Δy / Δx
Now we proceed to determine each equation of the line:
Case 1
Slope
m = [- 34 - (- 10)] / (13 - 5)
m = - 24 / 8
m = - 3
Intercept
b = y - m · x
b = - 10 - (- 3) · 5
b = - 10 + 15
b = 5
Equation of the line
y = - 3 · x + 5
Case 2
Slope
m = [- 3 - (- 11)] / [1 - (- 7)]
m = 8 / 8
m = 1
Intercept
b = y - m · x
b = 3 - 1 · 7
b = 3 - 7
b = - 4
Equation of the line
y = x - 4
Case 3

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.
The x-intercept is a = 1.077
The y-intercept is b = -4.677
The equation of line having x-intercept a and y-intercept b is -
x/a + y/b = 1
The equation of line having x-intercept 1.077 and y-intercept -4.677 is -
x/1.077 + y/-4.677 = 1
y/-4.677 = 1 - x/1.077
y = (1 - x/1.077)-4.677
y = -4.677 + 4.677x/1.077
y = -4.677 + 4.342x

Lydia has money in two savings accounts. One rate is 12% and the other is 13%. If she has $850 more in the 13% account and the total interest is $388, how much is invested in each savings account?
Lydia invested an amount of $1110 in the 12% savings account and $1960 in the 13% savings account.
Let's assume the amount invested in the 12% savings account "x". Then, the amount invested in the 13% savings account would be "x + 850".
The total interest earned is $388, so we can write the following two equations to represent the interest earned in each account:
0.12x + 0.13(x + 850) = 388
Expanding the second equation, we get:
0.12x + 0.13x + 110.5 = 388
Combining like terms and simplifying, we get:
0.25x = 277.5
Dividing both sides by 0.25, we get:
x = 1110
So, she invested $1106 in the 12% savings account and $1110 + 850 = $1960 in the 13% savings account.

What is a confidence interval?The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test.
In statistics, confidence is another word for probability.
Given In a random sample of 80 Americans, 36 wished that they were rich. In a random sample of 90 Europeans, 49 wished that they were rich.
Let p₁ = probability of Americans wanting to rich
p₂ = probability of Europeans wanting to rich
p₁ = 36/80 = 0.45
p₂ = 49/90 = 0.54
so CI = (p₁ - p₂) ± z₁(p₁p₂/n₁ + p₁p₂/n₂)

A coterminal angle is an angle that has the same initial point as another angle but has a different measure.
What is coterminal angle?A coterminal angle is an angle that has a different measure in degrees from another angle but the same initial point and direction. It is an angle that is similar to another angle in orientation but may be different in size. Coterminal angles are significant in trigonometry and have numerous uses in physics, engineering, and mathematics.
Angles are frequently measured in degrees in mathematics, and they can have a value between 0 and 360. It's crucial to remember that different measures might be assigned to the same angle based on the starting and finishing points. For instance, a 90-degree angle is one that begins at the positive x-axis and ends at the positive y-axis. Additionally, the same angle can be expressed as 450 degrees, -90 degrees, and so forth.

You purchase 200 shares for $70 a share ($14,000), and after a year the price falls to $80. Calculate the percentage return on your investment if you bought the stock on margin and the margin requirement was (ignore commissions, dividends, and interest expense): 20 percent
Answer: First, calculate the total value of the shares after the price fall to $80:
value = 200 shares * $80/share = $16,000
Then, calculate the amount of money borrowed:
borrowed = $14,000 / (1 - margin requirement)
= $14,000 / (1 - 0.20)
= $14,000 / 0.80
= $17,500
Finally, calculate the percentage return on investment:
return = (value - borrowed) / borrowed * 100%
= ($16,000 - $17,500) / $17,500 * 100%
= -6.06%
The return on investment is -6.06%, meaning that the investment lost 6.06% of its value.

Sample Data = 31.5, 36.0, 37.8, 38.5, 40.1, 42.2, 34.2, 36.2, 38.1, 38.7, 40.6, 42.5, 34.7, 37.3, 38.2, 39.5, 41.4, 43.4, 35.6, 37.6, 38.4, 39.6, 41.7, 49.3
(a) The value of z-score is calculated as follows,
μ =[tex]\sum_{i=1}^n X_i[/tex]/ n = 933.1 /24 = 38.88
σ = 3.61
z = X - μ / σ
= 37.8 - 38.88/3.61
= − 0.299
Therefore, the value of z-score is -0.299.
(b) Quartile:
Recalling the values: 31.5, 36, 37.8 ,38.5, 40.1 ,42.2, 34.2 ,36.2, 38.1, 38.7, 40.6 ,42.5, 34.7, 37.3 ,38.2, 39.5 ,41.4, 43.4, 35.6, 37.6 ,38.4 ,39.6 ,41.7, 49.3
Q₁ = ( n+1/4)th value
= (24+1/4)th value
= 6.25th value
= 36.2 + 0.25 x ( 37.3 − 36.2 )
= 36.47
and, M = ( n+1/2)th value
= (24+1/2)th value
= (24+1/4)th value
= 12.5 t h
= 38.4 + 38.5/2
= 38.45
Q₃ = 3( n+1/4)th value
= 3(24+1/4)th value
= 18.75 t h v a l u e
= 40.6 + 0.75 x ( 41.4 − 40.6 )
= 41.2
(c) Interquartile range = Q ₃ − Q ₁
= 41.2 − 36.47
= 4.25
Therefore, the IQR value is measure of spread of data, and here the value of IQR = 4.25.
(d) Lower fences = Q₁− 1.5 ( I Q R )
= 36.75 − 1.5 ( 4.25 )
= 30.375
Upper fences = Q ₃+1.5
= 41 + 1.5( 4.25 )
= 47.375
Hence, there is outliers since observations are not less than 30.375 and greater than 47.375.

The expression (5y + 2)(y - 3) is equivalent to:
The first question is about algebra with two variables. To calculate the algebra, sum up all the same variable and count the value.
We have an mathematical expression: (5y + 2)(y - 3).
Find the equivalent value!
The equivalent value is
= (5y + 2)(y - 3)
= 5y² + (-15y) + 2y - 6
= 5y² - 13y - 6
The expression of (5y + 2)(y - 3) is equivalent to 5y² - 13y - 6.
The second question is about length in coordinate plane. The following is the formula for the length in coordinate plane.
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
A line segment with endpoints (-6, 2) and (3, 1).
Find the length!
From the endpoints, we have
x₁ = -6y₁ = 2x₂ = 3y₂ = 1The length is
d = √[(3 - (-6))² + (1 - 2)²]
d = √[9² + (-1)²]
d = √[81 + 1]
d = √82
Hence,
The equivalent value is 5y² - 13y - 6.The line segment has a length of √82.Learn more about algebra here:

Which of the following functions is most likely to have the smallest value for y if x is large? (Assume k is positive.) a. a direct variation function with a small value for k c. an inverse variation function with a small value for k b. a direct variation function with a large value for k d. an inverse variation function with a large value for k
An inverse variation function with a small value for k. Therefore, option C is the correct answer.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
The association between x and y can be classified in two ways, as follows:
Direct proportional: when the input x increases, the output y also increases.
Inverse proportional: when the input x increases, the output y decreases.
For this problem, we need an inverse proportional function, that has the following format:
y = k/x.
The lower the value of k, the lower the value of y when x goes to infinity.
Therefore, option C is the correct answer.
