Which net represents this solid figure?

Answer:

Borrowings = $0.10 Billion

Owner's Equity = $0.40 Billion

Step-by-step explanation:

Total liabilities = deposits + borrowings

Borrowings = total liabilities - deposits

Borrowings in 2017 = $14.60 - 11.90 = $2.70 billion

Borrowings in 2018 = $14.80 - $12.20 = $2.60 billion

Borrowings from 2017-2018= 2.60 - 2.70 = $0.10 billion

Owner's Equity= total assets - total liabilities

Owner’s equity in 2017 = $16.2 - $14.6 = $1.6 billion

Owner’s equity in 2018 = $16.8 - $14.8 = $2 billion

Owner's Equity from 2017-2018= 2 - 1.6 = $0.4 billion

Hope this helps!

The Owner's Equity for commercial banks in  2017-2018 is $0.4 billion.

The given is,

Borrowings = $0.10 Billion

Owner's Equity = $0.40 Billion

Total liabilities = deposits + borrowings

So we have Borrowings = total liabilities - deposits

Borrowings in 2017

= $14.60 - 11.90

= $2.70 billion

Borrowings in 2018

= $14.80 - $12.20

= $2.60 billion

Borrowings from 2017-2018

= 2.60 - 2.70

= $0.10 billion

Owner's Equity= total assets - total liabilities

Owner’s equity in 2017

= $16.2 - $14.6

= $1.6 billion

Owner’s equity in 2018

= $16.8 - $14.8

= $2 billion

Owner's Equity from 2017-2018

= 2 - 1.6

= $0.4 billion

The series of questions is based on the entire concept of chemical equations. This is shown by balanced reaction equations.

A reaction equation shows the reactants and the products in a reaction. We shall now answer the questions individually;

1) The reactants in this equation are CaO and CO2. The product is CaCO3.

2) The simplest molecule that is formed between carbon and hydrogen is CH4 with the structure shown in the image attached.

3) The balanced equations are;

a) Na3PO4 + 3HCl -----> H3PO4 + 3NaCl

b) 2KClO3 → 2KCl  + 3O2

4)

a. 2NaBr + Ca  ----->CaBr2 + 2Na

b. 2Mg + O2  ------->2MgO

5) 3H2SO4 + 2Al -------> Al2(SO4)3 + 3H2

6) CH4 + 202 ---->CO2 + 2H2O

7)

a. molar mass of sucrose = 12(12) + 22(1) + 11(16) = 144 + 22 + 176 = 342 g/mol

b. molar mass of glucose = 6(12) + 12(1) + 6(16) = 72 + 12 + 96 = 180 g/mol

c. There are 6 * 10^23 molecules 1 mole of sucrose

d.  There are 6 * 10^23 atoms 1 mole of sucrose

8) The equation of the reaction is; NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2

Number of moles of baking soda= 42.00 g/84 g/mol = 0.5 moles

Since  the reaction is 1:1, 0.5 moles of CO2 is formed.

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

Frances bought 144 shares of Dwyn horticulture for $7.73 apiece. her broker charged her a commission of $46.15 for the purchase.

Then the total amount spent by the company will be

→ 144 × $7.73 + $46.15 = $ 1159.27

If the yearly dividend on Dwyn horticulture is 61 cents per share, then the annual yield on Frances’s stock will be

Answer:

X = 7.8

Step-by-step explanation:

First I will mark all the Information given to us:

Angle 1: 52 Degrees

Angle 2: 90 (Marked by the box) Degrees

Angle 3: 180-(90+52) Triangle Angle Sum Therom

Simplified Angle 3: 38 Degrees

Height: 10

Base: X
Hypo: ? (we will call this y)

In order to solve this problem we must use basic trig functions such as sin, cos and tan.

I will be applying sin for the degree measure of 52 as it is applicable there.

(Sin for refrence sin(angle measure)= side opposite to angle/hypo)

So this would be in our case:

Sin(52)=10/y

Simplify

y sin(52) = 10

y = 10/sin(52) (use a calculator make sure sin is in degrees not radians)

y=10/0.78801

y=12.69018 (We have our hypo value)

We can now apply a²+b²=c²

a²+10²=12.69018²

a²+100=161.040668432 (Calculator)

a²=61.040668432

a=√61.040668432 (calculator)

a=7.81285277168

Answer: Explicit Rule: a_n=30,000 • 2^n-1

Recursive Rule: a_n = 2a_n-1; a_1 = 30,000

Step-by-step explanation: the explicit rule for a geometric sequence is a_n = a_1 • r^n-1 and the recursive rule is a_n= r • a_n -1.
a_1 is the first term of the sequence, which is this case is 30,000. R is the common ration, which is 2 since it doubles each time. Substitute those numbers into the formulas and that’s what you’ll get. Hope this helps. God bless you!!!

We know the graph of an equation y = ax2 + bx + c where a ≠ 0 is a parabola. The parabola opens upwards if a > 0 and opens downwards if a < 0. The vertex of the parabola is the point where the axis and parabola intersect. Its x coordinate x = -b/2a and its y coordinate is found out by substituting x = -b/2a in the parabola equation.

The parabola given in the problem statement has a negative coefficient of x2 and hence it is a parabola which opens downwards. Also for the equation

a = -1, b = 6 and c = 112. Therefor the x-coordinate of the vertex is

x = -b/2a

= -(6)/[2(-1)]

= 3

Substituting the value of x = 3 in equation (1) we get,

Now y = -(3)2 + 6(3) + 112

= -9 + 18 + 112 = 121

So the vertex point coordinates are (3, 121) and the y value is 121.

To determine the equation of the line, we need to determine the slope and the y-intercept. Then, we will substitute the slope and the y-intercept in the slope intercept form equation to obtain the equation in slope intercept form.

Two points that lie on line: (0, 3) and (-5, 0)

[tex]\implies \text{Slope} = \dfrac{\text{Rise}}{\text{Run}} = \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

[tex]\implies \text{Slope} = \dfrac{3 - 0 }{0- (-5)}\\[/tex]

Answer:

Step-by-step explanation:

To show that circle A is similar to circle B the step required is Dilate circle A by a scale factor of 2 option (A) is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have two circles:

Circle A has a center of (2, 3) and a radius of 5

Circle B has a center of (1, 4) and a radius of 10

The standard circle's equation can be written as:

(x - h)² + (y - k)² = r²

The equation for circle A:

(x - 2)² + (y - 3)² = 5²

The equation for circle B:

(x - 1)² + (y - 4)² = 10²

To show that circle A is similar to circle B:

It is required to perform the geometric transformation:

Dilate circle A by a scale factor of 2.

The radius of circle A is 5 units and after dilation by a scale factor of 2, the radius of the circle becomes 10 which is the radius of circle B.

Thus, to show that circle A is similar to circle B the step required is Dilate circle A by a scale factor of 2 option (A) is correct.

A scale factor is simply the ratio of the corresponding sides of two similar objects. A scale factor of 4 simply means that the new shape is multiply four times the size of the original shape.

Given the data in the question;

Since scale factor of 4 means that the new shape is multiply four times the size of the original shape.

Volume of the larger box V = V° × SF
