Answer:
number of $20 bill = 4
Number of $5 bill = 5
Step-by-step explanation:
Given that:
Total number of $5 and $20 bills = 9
Let :
Number of $5 bills = x
Number of $20 bills = y
Combined worth of all bills = $105
x + y = 9 - - - (1)
5x + 20y = 105 - - - (2)
From (1)
x = 9 - y
Substitute x = 9 - y into (2)
5(9 - y) + 20y = 105
45 - 5y + 20y = 105
15y = 105 - 45
15y = 60
y = 60/15
y = 4
x = 9 - y
x = 9 - 4 = 5
Hence,
number of $20 bill = 4
Number of $5 bill = 5

Write an equation in slope intercept form for the graph below
Answer:
[tex] y = 10x [/tex]
Step-by-step explanation:
Finding the slope (m) of the line the following points in the line, (0, 0) and (2, 20):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{20 - 0}{2 - 0} = \frac{20}{2} = 10 [/tex]
y-intercept (b) is 0. The line intercepts the y-axis at 0. Thus, b = 0.
Substitute m = 10 and b = 0 in [tex] y = mx + b [/tex]
The equation in slope-intercept form for the graph would be:
✅[tex] y = 1x + 0 [/tex]

Two sales representatives leave from the same office. One travels 20 miles due north and the other travels 5 miles due west. How far apart are the sales representatives? Estimate the distance to the nearest tenth. 22.6 mi 16.4 mi 20.6 mi 11.8 mi
Answer:
d = 20.6 miles
Step-by-step explanation:
Given that,
Two sales representatives leave from the same office. One travels 20 miles due north and the other travels 5 miles due west.
It is required to find the distance between two representatives. It it is d. It can be calculated as the resultant if two values as follows :
[tex]d=\sqrt{20^2+5^2} \\\\=20.61\ mi[/tex]
So, the sales representative are 20.6 miles apart. Hence, the correct option is (c).
The height of a trapazoid can be expressed as (x-4) while the bases can be expressed as (x+4) and (x-9). If the area of the trapazoid is 99 cm squared, what is the length of the larger base
9514 1404 393
Answer:
≈ 17.228101 cm
Step-by-step explanation:
The area of a trapezoid is given by the formula ...
A = (1/2)(b1 +b2)h
Filling in the given information, we have ...
99 = (1/2)((x+4) +(x-9))(x -4) = (1/2)(2x -5)(x -4)
198 = 2x^2 -13x +20
2(x -3.25)^2 = 199.125
x = 3.25 +√99.5625 ≈ 13.228101
Then the length of the larger base is ...
x+4 = 17.228101 . . . cm

When the smoke cleared, the ratio of believers to skeptics was 15 to 7.If they were 105 believers, how many skeptics were there? PLEASE ANSWER QUICK
Answer:
[tex]\large\boxed{49}[/tex]
Step-by-step explanation:
Belivers to skeptics = 15 : 7
From the above ratio, we know that:
Believers = 15
Skeptics = 7
There were 105 believers, then we can rewrite the original ratio to be equal to the new one, to solve for x.
15 : 7 = 105 : x
Ratios can be written as fractions. Rewrite to simplify.
[tex]\frac{15}{7}[/tex] = [tex]\frac{105}{x}[/tex]
Cross multiply (numerator * denominator = numerator * denominator)
7 * 105 = 15 *x
735 = 15x
Divide both sides of the equation by 15
x = 49
There were 49 skeptics.

A chess club has 480 members but is losing 30 members each year. A computer club has 130 members and is gaining 20 members per year. When will the two clubs have the same number of members?
Answer:
The two clubs will have the same number of members after 7 years
Step-by-step explanation:
Let the number of years is x
∵ A chess club has 480 members but is losing 30 members each year
∵ The number of years = x
∴ The total members after x years = 480 - 30x ⇒ (1)
∵ A computer club has 130 members and is gaining 20 members per year
∵ The number of years = x
∴ The total members after x years = 130 + 20x ⇒ (2)
∵ The two clubs will have the same number of members after x years
→ Equate (1) and (2)
∴ 480 - 30x = 130 + 20x
→ Add 30x t both sides
∵ 480 - 30x + 30x = 130 + 20x + 30x
∴ 480 = 130 + 50x
→ Subtract 130 from both sides
∵ 480 - 130 = 130 - 130 + 50x
∴ 350 = 50x
→ Divide both sides by 50
∴ 7 = x
∴ The two clubs will have the same number of members after 7 years

The United States Declaration of Independence, officially The unanimous Declaration of the thirteen united States of America, is the pronouncement and founding document adopted by the Second Continental Congress meeting at Pennsylvania State House, which was later renamed Independence Hall, in Philadelphia, Pennsylvania, on July 4, 1776. Enacted during the American Revolution, the Declaration explains why the Thirteen Colonies at war with the Kingdom of Great Britain regarded themselves as thirteen independent sovereign states and no longer subject to British colonial rule. With the Declaration, the 13 states took a collective first step in forming the United States and, de facto, formalized the American Revolutionary War, which had been ongoing since April 1775.
The Declaration of Independence was signed by 56 of America's Founding Fathers who Second Continental Congress delegates from New Hampshire, Massachusetts Bay, Rhode Island and Providence Plantations, Connecticut, New York, New Jersey, Pennsylvania, Maryland, Delaware, Virginia, North Carolina, South Carolina, and Georgia. The Declaration became one of the most circulated and widely reprinted documents in early American history.
The Committee of Five drafted the Declaration to be ready when Congress voted on independence. John Adams, a leading proponent of independence, persuaded the Committee of Five to charge Thomas Jefferson with authoring the document's original draft, which the Second Continental Congress then edited. The Declaration was a formal explanation of why the Continental Congress had voted to declare its independence from Great Britain, a year after the American Revolutionary War broke out. The Lee Resolution for independence was passed unanimously by the Congress on July 2.
After ratifying the text on July 4, Congress issued the Declaration of Independence in several forms. It was initially published as the printed Dunlap broadside that was widely distributed and read to the public. Jefferson's original draft is currently preserved at the Library of Congress in Washington, D.C., complete with changes made by Adams and Benjamin Franklin, and Jefferson's notes of changes made by Congress. The best-known version of the Declaration is the signed copy now displayed at the National Archives in Washington, D.C., which is popularly regarded as the official document. This engrossed copy was ordered by Congress on July 19 and signed primarily on August 2, 1776.[2][3]
The sources and interpretation of the Declaration have been the subject of much scholarly inquiry. The Declaration justified the independence of the United States by listing 27 colonial grievances against King George III and by asserting certain natural a

6 Rearrange the linear equation so that it is in slope interceptform. Identify the slope (m) and the intercept (b). You must show your work for full credit
X-4=2(y - 3)
Answer:
[tex]y=\frac{1}{2}x+1[/tex] is in the slope-intercept form.
so the slope will be:
[tex]m=\frac{1}{2}x[/tex]and y-intercept will be:
b = 1Step-by-step explanation:
Given the equation
[tex]x-4=2(y - 3)[/tex]
As we know that [tex]y = mx+b[/tex] is the slope-intercept form of a line where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
Converting to slope-intercept form
[tex]x-4=2(y - 3)[/tex]
switching sides
[tex]2\left(y-3\right)=x-4[/tex]
[tex]2y-6=x-4[/tex]
[tex]2y=x-4+6[/tex]
[tex]2y=x+2[/tex]
[tex]y=\frac{1}{2}x+1[/tex]
As [tex]y = mx+b[/tex] is the slope-intercept form of a line where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
Therefore, [tex]y=\frac{1}{2}x+1[/tex] is in the slope-intercept form.
so the slope will be:
[tex]m=\frac{1}{2}x[/tex]and y-intercept will be:

In exercise 14 and 15, the value of the surface area of the cylinder is equal to the value of the volume of the cylinder. Find the value of x. then find the surface area and volume of the cylinder. 14)With the height of x and base of 6ft 15) with the height x and base of 10 m
Answer and explanation:
Volume of a cylinder = π r² h
Surface area of a cylinder = 2π r h + 2π r².
Since volume of cylinder = surface area of cylinder
π r² h=2π r h + 2π r²
Solving 14)
Given height x and base 6ft, radius will be 3ft
π r² h=2π r h + 2π r²
22/7*3²*x= 2*22/7*3*x+2*22/7*3²
=22/7*9*x= 2*22/7*3*x+2*22/7*9
= 28.286x=18.857x+2*28.286
=28.286x=18.857x+56.572
=9.429x=56.572
x=5.999ft( x cannot be a negative value)
15) Given height x and base 10 m, radius will be 5m
π r² h=2π r h + 2π r²
22/7*5²*x= 2*22/7*5*x+2*22/7*5²
78.5714x= 31.429x+157.1428
47.1424x=157.1428
x=3.333m( because x cannot be negative)
