the sum of two numbers is 76. if three times the small number is subtracted from the larger number, the result is 12. find the two numbers
Answer:
12, 60
Step-by-step explanation:
To solve this question, we can use a system of equations
1) x + y = 76
2) y - 3x = 12
Then, we can use the second equation to isolate y and substitute it into the second equation
y = 3x + 12
x + (3x + 12) = 76
4x + 12 = 76
4x = 64
x = 16, y = 60

Vincent Van Gogh’s most popular painting, The Starry Night was created by Van Gogh at the asylum in Saint-Rémy, where he’d committed himself in 1889. Indeed, The Starry Night seems to reflect his turbulent state of mind at the time, as the night sky comes alive with swirls and orbs of frenetically applied brush marks springing from the yin and yang of his personal demons and awe of nature.
The graph below represents an employee's earnings based on units sold. What can be interpreted from the slope of this graph?
A.
The employee earns an additional $100 for every one unit sold.
B.
The employee earns an additional $100 for every ten units sold.
C.
The employee earns an additional $1,000 for every one unit sold.
D.
The employee earns an additional $31,000 for every ten units sold.
Answer:
A
Step-by-step explanation:
From inspection of the graph, we can see that every time the x-value increases by 10, the y-value increases by 1000.
So, the employee earns an additional $1000 for every 10 units sold.
To calculate how much the employee earns for every 1 unit sold, divide $1000 by 10:
1000 ÷ 10 = 100
Therefore, the employee earns an additional $100 for every one unit sold.
Proof
This can be proved by calculating the slope (gradient) of the graph:
[tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
where [tex]\sf (x_1,y_1)[/tex] and [tex]\sf (x_2,y_2)[/tex] are two points on the line
When picking the two points, remember that the y-values are in thousands of dollars.
Two points on the line:
(0, 30000) and (20, 32000)
Substituting these into the formula:
[tex]\sf \implies slope=\dfrac{32000-30000}{20-0}=\dfrac{2000}{20}=100[/tex]
Therefore, the employee earns an additional $100 for every one unit sold.
The area of circles
Answer:
Formula for the area of a circle;
A = π[tex]r^{2}[/tex]Where 'π' represents pi(3.14 or 22/7), and 'r' represents the radius which is being squared.
Plug in the radius into this formula:-
A = π[tex]r^{2}[/tex]
Note: I will be using 3.14 as pi(π).A = 3.14(4^2)
A = 3.14(16)
A = 50.24 centimetres is the area for this circle.
HELP ME OUT PLS!!!!!
What is the volume of this cone? Use 3.14 for and round your answer to the nearest tenth. In your answer, give the volume of the cone rounded to the nearest tenth, and then explain how you calculated it. (Note: type out all of your work AND type out your explanation for FULL credit.)
We observe that the
height of the cone is 8 in.
radius of the cone is 2 in.
Volume of a cone = 1/3 π r² h
where R = radius and h = height
Using the formula we get :
Volume = 1/3 π 2 × 2 × 8
= 32 / 3 π cm³
= 33.5 cm³ ( rounded to 10)

Evaluate 3log2 + log200-log16
Answer:
2
Step-by-step explanation:
using the rules of logarithms
logx + logy = log(xy)
logx - logy = log ([tex]\frac{x}{y}[/tex] )
log[tex]x^{n}[/tex] ⇔ nlogx
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]
given
3log2 + log200 - log16
= log 2³ + log200 - log16
= log8 + log200 - log16
= log(8 × 200) - log16
= log1600 - log16
= log ([tex]\frac{1600}{16}[/tex] )
= log100
let [tex]log_{10}[/tex] 100 = n , then
100 = [tex]10^{n}[/tex] = 10²
thus value of expression is n = 2 , that is 2
[tex]2 \cdot 1[/tex]Answer:
Equal to 2
Step-by-step explanation:
1. Apply log rule: [tex]alog_c(b) = log_{c}(b^a)[/tex]
[tex]3log_{10}(2) = log_{10}(2^3)[/tex]
[tex]= log_{10}(2^3) + log_{10}(200) - log_{10}(16)[/tex]
2. Apply log rule: [tex]log_c(a) + log_c(b) = log_c(ab)[/tex]
[tex]log_{10}(2^3) + log_{10}(200) = log_{10}(2^3 \cdot 200)[/tex]
[tex]= log_{10}(2^3 \cdot 200) - log_{10}(16)[/tex]
[tex]2^3 \cdot 200 = 1600[/tex]
[tex]= log_{10}(1600) - log_{10}(16)[/tex]
3. Apply log rule: [tex]log_c(a) - log_c(b) = log_c(\frac{a}{b})[/tex]
[tex]log_{10}(1600) - log_{10}(16) = log_{10}(\frac{1600}{16})[/tex]
Divide the numbers: [tex]\frac{1600}{16} = 100[/tex]
[tex]= log_{10}(100)[/tex]
Rewrite 100 in power - base form: [tex]100 = 10^2[/tex]
[tex]= log_{10}(10^2)[/tex]
4. Apply log rule: [tex]log_a(x^b) = b \cdot log_a(x)[/tex]
[tex]log_{10}(10^2) = 2log_{10}(10)[/tex]
[tex]2log_{10}(10)[/tex]
5. Apply log rule: [tex]log_a(a) = 1[/tex]
[tex]log_{10}(10) = 1[/tex]
[tex]= 2 \cdot 1 = 2[/tex]

Answer:
y = x + 6
Step-by-step explanation:
The y-intercept is 6
and the slope is the change in y over the change in x, which is 1
So, use the equation y = m*x + c
m is the (slope) = 1
c is the (y-intercept) = 6
Your answer is: y = x + 6

2)y=x+2
Step-by-step explanation:
You can see on the first one y is just 4 less than x
You can see that the second one (graph) has a slope. As by the points, if you increase x by 0.5 you increase y by one.

x=4 (Vertical angles have to be equal to each other! If one side is 46 then the side vertical to it is 46!) **Plug number in for x to verify once again!**
Step-by-step explanation:
You need to understand vertical angles!!
Vertical Angles must be congruent and equal to each other!
You need to do:
10x+6=46
Subtract 6 from both sides

If there is 54% increase on a $54 item, then how much is the new cost for next year? Round to the nearest penny.
Round your answer to 2 decimal places.
Answer: $83.16
Step-by-step explanation:
This means that next year the item will cost 154% of what it is now.

The value of Betty's earnings of $55,000 in 1992 dolars is $44,141.25.
What is the value of earnings in 1992 dollars?The consumer price index measures the changes in price of a basket of good.
CPI = (cost of basket of goods in current period / cost of basket of goods in base period) x 100
Value of the current earnings in 1992 dollars = $55,000 / 1.246 = $44,141.25
