n is m % of what? Help Please!!!!
9514 1404 393
Answer:
what = 100n/m
Step-by-step explanation:
You are given ...
n = m% × what
You know that % is fully equivalent to /100, so this can be written as ...
n = (m/100) × what
If we want to find "what", we can multiply by the reciprocal of its coefficient. That is, multiplying by 100/m gives ...
(100/m)n = (100/m)(m/100)×what
what = 100n/m
_____
Example
13 = 20% of what . . . . . n = 13, m = 20
what = 100(13)/20 = 65
so, 13 = 20% of 65.

What is the salesman's commission as a percent of his total monthly sales?
Enter your answer in the box.
Answer:
6%
Step-by-step explanation:

Anton is constructing an angle congruent to ∠PQR. With his straightedge, he draws and labels AB−→. He places the compass point on point Q and draws an arc that intersects QP−→− and QR−→−. He labels the point where the arc intersects QP−→− as point S and the point where the arc intersects QR−→− as point T. What should Anton do next?
Answer: i just took the test yesterday and got it right
With the same compass opening, place the compass point on point A and draw a long arc through AB−→−.
hopefully this helps. i would have helped you sooner if i seen it before now
Place the compass point on point A and draw a long arc through AB using the same compass opening.
What is arc ?An "arc" is a smooth curve that connects two points. In general, an arc is a section of a circle. It is essentially a portion of a circle's circumference. An arc is a type of curve. An arc can be a portion of another curved shape, such as an ellipse, but it most commonly refers to a circle.
The arc of a circle is defined as a portion or segment of a circle's circumference. A chord of a circle is a straight line formed by connecting the two ends of an arc. A semicircular arc is one that is exactly half the length of a circle.
A chord of a circle is a straight line that can be drawn by connecting the two ends of an arc.

Answer:
x = 40
y = 62
Step-by-step explanation:
I figured out the answer by finding the x on the left triangle first by writing an equation:
(3x - 18) + (x + 7) + (x - 9) = 180
once I worked that I plugged in the number which was 40.
Then for the triangle to the right I also plugged in the numbers for x and got 118 degrees I took 180 and subtracted 118 to get my answer of 62 for y.

for which of the following does f(-3)=0 select all that apply
A. f(x) = (x - 3)^2
B. f(x) = -x^2 – 3x
C. f(x) = -(x + 3)^2
D. f(x) = x^2 + 5x + 4
E. f(x) = 2x - 3(x + 1)
F. f(x) = -2(x - 2) + 3x
The function which has the value of 0 at x = -3 are C. f(x) = (x + 3)² and E. f(x) = 2x - 3(x + 1).
What is Function?
A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
A. f(x) = (x - 3)²
Substituting x = 3,
f(-3) = (-3 - 3)² = 36
B. f(x) = x² - 3x
f(-3) = (-3)² - (3 × -3) = 9 + 9 = 18
C. f(x) = (x + 3)²
f(-3) = (-3 + 3)² = 0
Here the function value is 0.
D. f(x) = x² + 5x + 4
f(-3) = 9 - 15 + 4 = -2
E. f(x) = 2x - 3(x + 1)
f(-3) = -6 - 3(-3 + 1) = 0
Here the function value is 0.
F. f(x) = -2(x - 2) + 3x
f(-3) = 1
Hence the required functions are C. f(x) = (x + 3)² and E. f(x) = 2x - 3(x + 1).

If A=[1 0 -1 7] find K such that A^2-8A-ki-KI=0
Answer:
K = -7
Step-by-step explanation:
If A=[1 0 -1 7] find K such that A^2-8A-ki-KI=0
Given the 2×2 matrices
A = [tex]\left[\begin{array}{ccc}1&0\\-1&7\\\end{array}\right][/tex]
We are to find K if =0
A² = [tex]\left[\begin{array}{ccc}1&0\\-1&7\\\end{array}\right][/tex][tex]\left[\begin{array}{ccc}1&0\\-1&7\\\end{array}\right][/tex]
A² = [tex]\left[\begin{array}{ccc}1&0\\-8&49\\\end{array}\right][/tex]
8A = 8[tex]\left[\begin{array}{ccc}1&0\\-1&7\\\end{array}\right][/tex]
8A = [tex]\left[\begin{array}{ccc}8&0\\-8&56\\\end{array}\right][/tex]
Since [tex]I = \left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right] \\[/tex]
[tex]KI = \left[\begin{array}{ccc}K&0\\0&K\\\end{array}\right][/tex]
Substitute the resulting matrices into the expression above:
A^2-8A-KI = [tex]\left[\begin{array}{ccc}1&0\\-8&49\\\end{array}\right][/tex] - [tex]\left[\begin{array}{ccc}8&0\\-8&56\\\end{array}\right][/tex] - [tex]\left[\begin{array}{ccc}K&0\\0&K\\\end{array}\right][/tex] =[tex]\left[\begin{array}{ccc}0&0\\0&0\\\end{array}\right][/tex]
From the expression, we have the equations;
1 - 8 - k = 0
-7 - k = 0
-7 = k
k = -7
Hence the value of K is -7

b) The adjoining cylindrical vessel is 70 CM high and the radius
of its base is 35cm. If it contains some water up to the height
of 20 cm, how much water is required to fill the vessel
completely
[tex]\large\boxed{\pink{\sf \leadsto The \ Volume \ of \ water \ needed \ to \ be \ filled \ is \ 192,500 cm^3}}[/tex]
Step-by-step explanation:Given that , cylindrical vessel is 70 cm high and the radius of its base is 35cm . it contains some water up to the height of 20 cm .
And we need to find the water required to fill it completely .
Figure :-
[tex]\setlength{\unitlength}{1 cm}\begin{picture}(12,12)\linethickness{0.4mm}\put(0,0){\line(0,1){5}} \put(3,0){\line(0,1){5}}\qbezier(0,5)(1.5,4)(3,5)\qbezier(0.001,0)(1.5,1)(3,0)\qbezier(0,5)(1.5,6)(3,5)\qbezier(0.001,0)( 1.5, - 1)(3,0)\put(3.5,2){\vector(0,-1){2}}\put(3.5,3){\vector(0,1){2}}\put(3.5,2.5){$\sf 70 cm $}\put(1.4,0){\line(1,0){1.6}} \put(1.4,0.2){$\sf 35cm$}\qbezier(0,2.5)(1.5,3.5)(3,2.5)\qbezier(0,2.5)(1.5, 1.8)(3,2.5)\put(-1,1){\vector(0,-1){1}}\put(-1,1.5){\vector(0,1){1}}\put(-1.3,1.2){$\sf 20cm $}\end{picture}[/tex]
Let us take the Volume of Cylinder be V and the volume of cylinder filled be v . Let the volume required to be filled be X .
From the figure it's clear that , Volume of water required to fill the cylindrical vessel completely will be :-
[tex]\tt:\implies v + x = V \:\: \bigg\lgroup \red{\bf As \ per \ our \ assumption }\bigg\rgroup \\\\\tt:\implies x = V - v \\\\\tt:\implies x = \pi r^2 H - \pi r^2 h \\\\\tt:\implies x = \pi r^2 ( H - h ) \\\\\tt:\implies x = \pi r^2 ( 70 cm - 20 cm ) \\\\\tt:\implies x = \dfrac{22}{7} \times (35 cm)^2 \times 50 cm \\\\\tt:\implies x = \dfrac{22\times 35 cm \times 35 cm }{7} \times 50 cm \\\\\underline{\boxed{\red{\tt \longmapsto Volume_{fill } = 192,500 cm^3}}}[/tex]
Hence the required volume of water to be filled is 192,500 cm³.The Jacksons

A line is perpendicular to y = -x + 1
and intersects the point (-5,1).
What is the equation of this
perpendicular line?
Answer:
y = 5x + 26
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{1}{5}[/tex] x + 1 ← is in slope- intercept form
with slope m = - [tex]\frac{1}{5}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{5} }[/tex] = 5 , thus
y = 5x + c ← is the partial equation
To find c substitute (- 5, 1) into the partial equation
1 = - 25 + c ⇒ c = 1 + 25 = 26
y = 5x + 26 ← equation of perpendicular line
Give the rule for translating a point 4 units left and 8 units up
Answer:
(x-4,y+8)
Step-by-step explanation:
Given
[tex]Point = (x,y)[/tex]
Required
Translate
4 units left8 units up8 units up
The general rule for up translation is;
[tex]f'(x,y) = f(x,y+h)[/tex]
Where h is the unit translated up
In this case:
[tex]h = 8[/tex]
So, we have:
[tex]f'(x,y) = f(x,y+8)[/tex]
4 units left
The general rule for up translation is;
[tex]f'(x,y) = f(x-b,y)[/tex]
Where b is the unit translated left
In this case:
[tex]b = 4[/tex]
So, we have:
[tex]f"(x,y) = f(x -4,y+8)[/tex]
Hence, the rule of translation is: (x-4,y+8)
Answer:
translation is
x-4,y+8
