Take a factor out of the square root and simplify the expression:
[tex]-0.05*\sqrt{28,800}[/tex]
Answer:
[tex] - 6 \sqrt{2} [/tex]
Step-by-step explanation:
simplify
[tex] \sqrt{28800} [/tex]
to
[tex]120 \sqrt{2} [/tex]
then
-0.05 × 120 = -6
then we have our answer
-6√2

At a baseball game, a hamburger costs $2 more than
a hotdog. If 14 hamburgers and 13 hotdogs cost
$136, how much does each hamburger and hotdog
cost?
Show your work at the bottom of this page.
what is x? what is y? how much did a hamburger cost?
how much did a hotdog cost?
Answer:
Hamburger = $6
Hotdog = $4
Step-by-step explanation:
136 - 14(2) = 108
108 / 13 + 14 = 4
If a hamburger is 2 dollars more than you would just add 2 to this
11. What is the value of xin the solution to this system of equations?
3x - 5y = 22
y = -5x + 32
Answer:
x = ¹³⁄₂
y = ⁻¹⁄₂
Explanation:
[tex]\bold{\begin{bmatrix}3x-5y=22\\ y=-5x+32\end{bmatrix}}[/tex]
Substitute y = -5x + 32[tex]\bold{\begin{bmatrix}3x-5\left(-5x+32\right)=22\end{bmatrix}}[/tex]
Simplify[tex]\bold{\begin{bmatrix}28x-160=22\end{bmatrix}}[/tex]
Isolate x for 28x - 160 - 22: x = ¹³⁄₂[tex]\bold{\mathrm{For\:}y=-5x+32}[/tex]
Substitute x = ¹³⁄₂[tex]\bold{y=-5\cdot \frac{13}{2}+32}[/tex]
-5 · ¹³⁄₂ + 32 = ⁻¹⁄₂
y = ⁻¹⁄₂x = ¹³⁄₂
y = ⁻¹⁄₂

Solve for x 2x-13=3
X=8
X=-5
X=10
X=-8
Answer:
X=8
Step-by-step explanation:
2x-13=3 first, add 13 to both sides
2x=16 second, divide by 2 on both sides
x=8 This is the right answer

Consider the Function
Which function could be the inverse of function f?
Answer:
Explanation below, despite missing details in question.
Step-by-step explanation:
The function isn't given but we know it's labelled "f".
The inverse of a function (likewise the inverse of any other quantity) is simply the function turned up-side-down.
To invert a function, you switch the places of both numerator and denominator. Example:
f = [tex]\frac{x}{y}[/tex]
the inverse of the function above is y/x
If the function is not in fraction form or doesn't have a visible denominator, take the denominator to be 1.
The denominator of every number or function is 1, so you'll be correct doing this.
If f = 2n +5 then the inverse of f will be [tex]\frac{1}{2n + 5}[/tex]
NOTE: Inverse of f ≡ 1/f ≡ [tex]f^{-1}[/tex]

Triangles
• If one side of a triangular piece of yard area is roughly one-third the perimeter,
the second side is roughly one-fifth the perimeter, and the third side is 7yards,
what is the perimeter of the triangle?
Answer:
15m
Step-by-step explanation:
The third side = (2/3 - 1/5) of the perimeter = 7/15 of the perimeter = 7m
The first side is 1/3 (=5/15) of the perimeter = 5m
The second side is then 3m ( or 1/5=3/15 of the perimeter).
The triangle perimeter is 15 meters (=7 m+5m+3m)

Equation of parallel line:
Answer:
a)The equation of the Parallel line to the given line is
7x -y +18 =0
b) The equation of the Perpendicular line to the given line is
-x +7y +18 =0
Step-by-step explanation:
Step(i):-
Given that equation of the line y = 7x -5
7x -y -5=0
The equation of the Parallel line to the given line is
7x -y +k=0
This line is passes through the point ( -3,-3)
7 ( -3) -(-3)+k=0
-21 +3+k=0
-18 +k=0
k =18
The equation of the Parallel line to the given line is
7x -y +18 =0
Step(ii):-
Given that equation of the line y = 7x -5
7x -y -5=0
The equation of the perpendicular line
b x -ay +k=0
The equation of the Perpendicular line to the given line is
-x +7y +k=0
This line is passes through the point ( -3,-3)
-(-3)+7(-3) +k=0
3 - 21 +k=0
-18 +k=0
k =18
The equation of the Perpendicular line to the given line is
-x +7y +18 =0
Determine two coterminal angles (one positive and one negative) for each angle. Give your answer in radians. (Enter you answer as a comma-separated list)
Answer:
The answer is below
Step-by-step explanation:
Coterminal angles are angles with the same terminal side at standard position (angles with the initial side on the positive x-axis). Coterminal angles may have different magnitude but they would have equal sides and vertices.
Coterminal angles can either be positive or negative. The positive coterminal is gotten by adding 2π rad or 360° while the negative coterminal is gotten by subtracting 2π rad or 360°.
a)
Positive coterminal angle = [tex]\frac{5\pi}{4}+2\pi=\frac{13\pi}{4} \ rad[/tex]
Negative coterminal angle = [tex]\frac{5\pi}{4}-2\pi=\frac{-3\pi}{4} \ rad[/tex]
b)
Positive coterminal angle = [tex]\frac{-9\pi}{4}+2\pi=\frac{-\pi}{4}+2\pi=\frac{7\pi}{4} \ rad[/tex]
Negative coterminal angle = [tex]\frac{-9\pi}{4}-2\pi=\frac{-17 \pi}{4} \ rad[/tex]

Nikhil, Davina and Sid share a tin of celebrations amongst themselves in the ratio of 8:12:20 respectively.
Given that Davina gets 48 sweets, how many sweets did Nikhil get?
Answer:
Step-by-step explanation:
find what y and x equals
y=-2x
y=2x-1
Answer:
The correct answer is "[tex]x=\frac{1}{4}[/tex]" and "[tex]y=-\frac{1}{2}[/tex]"
Step-by-step explanation:
As we know,
y = -2x ...(equation 1)
y = 2x-1 ...(equation 2)
On putting the value of "equation 1" in the "equation 2", we get
⇒ [tex]y=2x-1[/tex]
⇒ [tex]-2x=2x-1[/tex]
On adding "2x" both sides, we get
⇒ [tex]-2x+2x=2x-1+2x[/tex]
⇒ [tex]0=4x-1[/tex]
⇒ [tex]4x=1[/tex]
⇒ [tex]x=\frac{1}{4}[/tex]
Now,
On putting the value of "x" in equation 1, we get
⇒ [tex]y=-2x[/tex]
⇒ [tex]y=-2\times \frac{1}{4}[/tex]
⇒ [tex]y=-\frac{1}{2}[/tex]

constant of proportionality: k = y/x
- plug in numbers to find:
k = 84.45 / 5
= 16.89
so, constant of proportionality: 16.89
equation:
y = kx (now plug in)
y = 16.89x
- plug in again to find the amount of cakes
y = 16.89x
895.17 = 16.89x
x = 53
53 cakes
