$6, 150. Last week he sold the stock for. $8,250.
what was his gross capital gain?
Frank's gross capital gain was $2,100.
What is gross capital gain?
the discrepancy between the overall cost base of your asset and your capital gains. Your share of the capital gain - If more than one person owns this asset, your share of the gain is equal to the percentage of the asset that you personally hold.
You want the gross capital gain resulting from selling a stock purchased for $6,150 and sold for $8,250.
Capital Gain
The capital gain resulting from the sale is the difference between the selling price and the purchase price:
gain = selling price - purchase price
gain = $8,250 -6,150
gain = $2,100
Frank's gross capital gain was $2,100.

Daisy has two measuring jugs, A and B. The volume of each measuring jug will be A and B will be 500 ml and 400 ml.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, Daisy has two measuring jugs, A and B, that together have a capacity of 900 ml, A jug of water is filled by Daisy. Afterward, she transfers water from jug A into jug B. Following this, jug A has 500 ml of water left.
Total volume = volume in jug A + volume in Jug B
If there are 500 ml of water remaining in jug A.
900 ml = 500 ml + volume in Jug B
volume in Jug B = 900 - 500
volume in Jug B = 400 ml
Thus, Daisy has two measuring jugs, A and B. The volume of each measuring jug will be A and B will be 500 ml and 400 ml.

How much simple interest does $2,560 earn in 17 months at a rate of 1*1/8 Round to the nearest cent.
The simple interest of the $2,560 earned in 17 months at a rate of 1*1/8 will be; $185.90
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of the principal amount, rate, and period.
The formula for simple interest is:
Simple Interest = (Principal × Rate × Time) / 100
Where I am interested
P ⇒ amount deposited.
R ⇒ interest rate
T ⇒ period for investing
Given that the time is 17 months = 17/12 years

of his monthly budget should Jacob allocate for rent?
The percentage of monthly budget should Jacob allocate for rent is 27.7%.
What is termed as the percentage?A percentage is a ratio with the second term being 100. Percentage refers to parts per hundred. The term is derived from the Latin word per centum, that also means "per hundred." In mathematics, the symbol% stands for percent.For the given question;

Jacob's one week earning will be $1,350/2 = $675.
Considering there are 5 weeks in a months.
Jacob's one month earning will be $675×5 = $3,375.
The total monthly rent = $936.
Let 'x' be the percentage Jacob pay for the rent.
Then,
x% of 3,375 = 936
Simplifying the expression.
3,375x/100 = 936
x = 93,600/3,375

How to Graph an Inequality?Given the inequality, y < 1 - 3x, we need to determine if the line of the inequality graph will be dashed or solid, the slope (m) of the line, and the y-intercept (b).
The slope (m) of the inequality y < 1 - 3x is -3. This means the line would be a declining line where the rise/run = -3.
The y-intercept (b) of the inequality y < 1 - 3x is 1. This means the line would intercept the y-axis at y = 1.
The boundary line of the inequality graph for y < 1 - 3x would be a dashed line because of the inequality sign "<". It also means the shaded part would be below the boundary line, because, the inequality sign, "<" means the the values are not included.

Answer:
A. Yes, Rectangle A is a scaled copy of rectangle B.
B. Yes, Rectangle B is a scaled copy of rectangle A.
C. No, Rectangle A is not a scaled copy of rectangle C.
Step-by-step explanation:
Rectangle A has dimensions 12x8 and Rectangle B has length 15x10.
We see that sides of A and B are proportional because
[tex]\frac{12}{15} = \frac{8}{10}[/tex]
So we say that since sides are proportional A and B are similar or scaled copy of each other.
Since A is smaller and B is bigger, a is 0.8 scaled copy of B. Similarly B has an enlargement scale factor = 1.25 Rectangle C has 30x15, not proportion with sides of A and B. Hence we find that C is neither a scaled copy of A nor B

in triangle ABC , angle A = 30 degrees and angle C = 35 degrees. what is angle B degrees?
Answer:
115°
Step-by-step explanation:
The sum of the three angles in a triangle is always 180°
m∠A + m∠B + m∠C = 180°
m∠B = 180 - m∠A - m∠C
m∠B = 180 - 30 - 35 = 115
–8(y-7)=2y+6Simplify your answer as much as possible
You have the following equation:
-8(y -7) = 2y + 6
In order to solve for y, proceed as follow:
-8(y -7) = 2y + 6 expand the factor right side
-8y + 56 = 2y + 6 subtract 2y and subtract 56 both sides
-8y - 2y = 6 - 56 simplify
-10y = -50 divide by -10 both sides
y = -50/(-10)
y = 5
Hence, the value of y is 5

A pyramid has an isosceles triangle base with sides of 25,25 and 48 units.
The height of the pyramid is 30 units. The volume of the pyramid is 13What is the volume?We have a pyramid with four sides and a square base. Two-thirds of the pyramid's sides make up its height. The volume of a pyramid is 1, and we need to determine which of them matches our volume. Third, multiplying the length by the width gives us our base's area, which is s times s, or s square.This tells us that our base's height is equal to two-thirds of its side because it is a square base.
That makes it 2 to times s, or 2 s over 3. So we incorporate that into our equations next. We have a volume that is equal to 1/s squared / 2 / s spanning 3 points.Therefore, a pyramid has an isosceles triangle base with sides of 25,25, and 48 units.

a) How much will he owe his father three months from now?
b) How much money did he borrow from his father?
In three months, he will owe his father $2500 less $1200, or $1300.
One of the four fundamental operations in mathematics is addition, along with subtraction, multiplication, and division. The entire amount or sum of the two whole numbers is obtained by adding them.
Tom's payment for 7 months is 400 * 7 = $2800.
He borrowed $5300 ($2500 plus $2800).
