Answer:
the measurements must be incorrect because when you solve it, it is obvious that 6x is not a 90 degree angle and 3x is not 45 degrees.
Step-by-step explanation:
Answer:
x=20
Step-by-step explanation:
Ques5) x value is 20 because 3x+6x=180
=>9x=180
=> x=180/9
=> x=20
Ques6) 6x= 6*x which is equal to 6*20=120
Ques7) 3x=3*x which is equal to 3*20=60
This is correct because 120+20=180 which is a straight angle given in the question. Hope this helped, Thank you.
Find the x-intercept of the graph of the equation y = -2.65x + 25.
What does the x-intercept mean in terms of the situation?
Answer:
x=9.4
Step-by-step explanation:
x intercept is the point where the graph crosses the x axis and y always =0
-2.65x+25=0
-2.65x=-25
x=-25/-2.65
x=500/53
x=9.4
tan x = -0.25 for 0< x < 720
Answer:
Below in bold.
Step-by-step explanation:
The smallest angle for which -0.25 is the tangent is in the second quadrant and is 165.96 degrees. The other angle in the fourth quadrant is 345.96 degrees.
So for the range 0 to 720, x = 165.96, 345.96 and 360 + 165.96 = 525.96 and 345.96+360 = 705.96 degrees.

PLS HELP, I'LL GIVE YOU NITRO ON DISC0RD!!! Jose ran a concession stand last Saturday and made $79.80 from selling a total of 42 hot dogs and hamburgers. Each hot dog sold for $1.50 and each hamburger sold for $2.70. Which system of equations can be used to determine the number of hot dogs, x, and hamburgers, y, that were sold?
Answer:
1.50x + 2.70y - 84 = 79.80
Explanation: I REALLY don't know if this is right, but I hope I helped you out at least a little bit.
Answer:
x + y = 42
1.50x + 2.50y = $79.80
x = 28 hot dogs
y = 14 hamburgers
Step-by-step explanation:
x = hot dogs
y = hamburgers
Equation:
x + y = 42
1.50x + 2.50y = $79.80
I used Substitution
x = 42 - y
1.50(42 - y) + 2.50y = 79.80
63 - 1.50y + 2.70y = 79.80
63 + 1.2y = 79.80
Substract 63 from both sides
1.2y = 16.8
Divide 1.2 on both sides
y = 14
x + y = 42
x + 14 = 42
x = 28
y = 14
Don't know how to explain that well, I hope this helps.

The momentum of an object, p, is determined by its mass, m, and its velocity, v. The formula p=mv shows this relationship. Which equation shows the formula p=mv correctly solved for v?
A.
v=pm
B.
v=p/m
C.
v=p−m
D.
v=m/p
On solving for [v], we get v = p/m.
What is momentum?Momentum is defined as the product of mass and velocity of a body. Mathematically, we can write vector as -
p = mv
It is a vector quantity. In a three dimensional coordinate, the momentum vector can be resolved as -
[p] = p[x] a[x] + p[y] a[y] + p[z] a[z]
[p] = m {v[x] a[x] + v[y] a[y] + v[z] a[z]}
Given is the momentum of an object whose formula is p=mv.
We have the formula for momentum as -
p = mv
We can solve for [v] as -
p = mv
Divide by [m] on both sides, we get -
p/m = mv/m
v = p/m
Therefore, on solving for [v], we get v = p/m.

Answer:
[tex] r^2 [/tex]
All choices are incorrect.
Step-by-step explanation:
Remember that [tex] r = r^1 [/tex].
Also remember the rule: [tex] \dfrac{a^m}{a^n} = a^{m - n} [/tex]
[tex] \dfrac{r^3}{r} = [/tex]
[tex] = \dfrac{r^3}{r^1} [/tex]
[tex] = r^{3 - 1} [/tex]
[tex] = r^2 [/tex]
Answer: [tex] r^2 [/tex]
All choices are incorrect.
6. The amount of time it took four soccer players to run from one goal line to the other is as follows:
Player #1 - 10.4 seconds
Player #2 - 10.1 seconds
Player #3 - 9.9 seconds
Player #4 - 9.4 seconds.
If the data was only accurate to the ones place, which soccer player's time would be different from the others?
A Player #1
B Player #3
C Player #2
D Player #4
Given:
The amount of time it took four soccer players to run from one goal line to the other is:
Player #1 - 10.4 seconds
Player #2 - 10.1 seconds
Player #3 - 9.9 seconds
Player #4 - 9.4 seconds
To find:
Soccer player whose time would be different from the others, if the data was only accurate to the ones place.
Solution:
We need to approximate the time to the ones place.
Player #1 - 10.4 seconds = 10 seconds
Player #2 - 10.1 seconds = 10 seconds
Player #3 - 9.9 seconds = 10 seconds
Player #4 - 9.4 seconds = 9 seconds
Therefore, the time of players 4 is different from others.
Hence, the correct option is D.

Simplify 12edf – 13def. State a property that you can use.
Answer:
-def. In multiplication, the order doesn't matter.
Step-by-step explanation:
A crucial property you can use to simplify this is the fact that, in multiplication, order doesn't matter.
3 * 2 = 6
2 * 3 = 6
5 * 2 * 3 = 30
2 * 3 * 5 = 30
3 * 2 * 5 = 30
Thus,
edf, or
e * d * f
is the same as def,
d * e * f
e * d * f = d * e * f
edf = def
Thus, 12edf is the same as 12def. We can put this in our expression:
12edf - 13def
12def - 13def
Now, we can see that this will equal -1def or -def
12def - 13def
-1def
-def
Answer: -def. In multiplication, the order doesn't matter.
if
f(x)=x^2+2x-4
and
g(x)=3x+1
find
f(g(x))=__x^2+__x+__
Step-by-step explanation:
f(x) = x² + 2x - 4
g(x) = 3x + 1
f(g(x)) = f(3x + 1)
f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4
= 9x² + 6x + 1 + 6x + 2 - 4
= 9x² + 12x -1

Answer:
d = [tex]\sqrt{146}[/tex]
Step-by-step explanation:
[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d= \sqrt{(-5-0)^2+(-9-2)^2}\\d= \sqrt{(-5)^2+(-11)^2}\\d= \sqrt{25+121}\\d= \sqrt{146}[/tex]
Rewrite the equation by completing the square.
f(x) = x^2 - 2x + 17
f(x) = (x + |?|)^2 + |?|
Answer:
f(X)= (x-1)²+16

What is the image of (-7, -9) after a reflection over the x-axis?
Answer:
(-7,9)
Step-by-step explanation:
When you flip over the x-axis, the y-value changes its sign. Vice versa.
[tex]\huge\boxed{\boxed{\bold{(-7, 9)}}}[/tex]
[tex]\hrulefill[/tex]
To reflect a point across the [tex]x[/tex]-axis, multiply or divide its [tex]y[/tex] coordinate by [tex]-1[/tex]:
[tex]P'=(-7, -9*-1)[/tex]
Multiply:
[tex]P'=\large\boxed{(-7, 9)}[/tex]
An image is attached showing the original point ([tex]P[/tex]) and its image ([tex]P'[/tex]).

A statistics class with 40 students consists of 30 students with no income, 10 students with small incomes from part-time jobs, and a professor with a very large income that is well deserved. Which is better for describing the income of a typical person in this class: mean or median? Explain.
The median would be better for describing the income of a typical person in the class because the professor's large salary skews the data to the right while all the students are towards the left and center.
