Step-by-step explanation:
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.
A data set is normally distributed with a mean of 63 and a standard deviation of 10.4.
What percentage of the data is between 45 and 77?
Enter your answer as a number to the nearest whole percentage, like this: 42%
Answer:
87%
Step-by-step explanation:
The percentage of normally-distributed data between 45 and 77 in a data set with mean 63 and standard deviation 10.4 can be found by any of a number of calculators, apps, web sites, or spreadsheets.
The percentage is 87%.
4. There are two numbers that add together and the result is 63. If you subtract the same number together, the result is 28.
a) Create two equations from the statement above. Make sure to specify what each variable means.
b) Solve the system of equations by Elimination.
Answer:
45.5 and 17.5
Step-by-step explanation:
a)
Let Number 1 be X and Number 2 be YX + Y = 63X - Y = 28b)
From adding 1. and 2. ,2X = 91X = 45.5Y = 63 - 45.5 = 17.5How do you solve this? I don't understand
Answer:
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
10x=40
Do 40 divided by 10
x=4
To verify: plug 4 for x which should be 40 added to 6 is 46!

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]
HELP PLEASE PYTHAGOREOM THEOREM
Pythagorean Theorem:
[tex]a^2 + b^2 = c^2[/tex]
Since 10 and 24 are the legs, "x" has to be the hypoteneuse. "a" and "b" are the legs (10 and 24).
Now, replace the values in.
[tex]10^2+24^2 = x^2[/tex]

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)

Do the graph and table to find the equation that represents the relationship for each of the 2 questions! :)
Answer:
1) y=x-4
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.
Thus, y=x+2
Hope this helped! I can't see much of the question :)
Can someone Help me please
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

I drew a diagram of all the triangles to compare the statements given to each other
I marked the triangle sides with lines to show congruency in length.
One line for AB = DF
Two lines for AB = GI
Three lines for BC = HI
Four lines for DE = HI
The angles are all marked for the last sentence we are given.
The first and third triangles are the only ones similar. This is because of SAS congruence as given in the Diagram. AB = GI, angle B = angle I, BC = IH
The second triangle is different from the rest, and even if we tried to rotate it ad compare it, it would still be wrong.

Corresponding angles: ∠1 and ∠5; ∠3 and ∠7; ∠2 and ∠6; and ∠4 and ∠8.
