Answer: out of 1400 students 672 of them are males.
Step-by-step explanation:
Step 1 turn the percent into a decimal
0.52*1400= 728
728 is the number of female students
Step 2 subtract 728 from 1400
1400-728=672

A random sample of 374 United States pennies were collected and the age of each penny was determined
Answer:
16
Step-by-step explanation:
The interquartile range of pennies is 16. Interquartile range is also known as 50% or the midpoint. Interquartile is the smallest point of measurement. The whole data set is divided into quartiles and data is spread evenly in every range.

Answer:
There were 53 cakes ordered.
Step-by-step explanation:
☆Cross multiply.
[tex] \frac{3 \: cakes}{50.67 \: dollars} = \frac{x}{895.17 \: dollars} \\ \\ \frac{50.67x}{50.67} = \frac{2685.51}{50.67} \\ \\ x = 53[/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

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

A bag contains counters that are red, black , or green . 1/3 of the counters are red 1/6 of the counters are black There are 15 green counters in the bag. How many black counters are in the bag ?
i’ll give brainliest;)
Answer:
Number of black counters = 5
Step-by-step explanation:
Let,
x be the total number of counters
Number of red counters = [tex]\frac{1}{3}x[/tex]
Number of black counters = [tex]\frac{1}{6}x[/tex]
Number of green counters = 15
Now,
Red counters + Black counters + Green counters = Total counters
[tex]\frac{1}{3}x+\frac{1}{6}x+15=x\\\\\frac{2x+x+90}{6}=x\\\\3x+90 = 6x\\90 = 6x-3x \\90 = 3x\\3x = 90[/tex]
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{90}{3}\\x=30[/tex]
Number of black counters = [tex]\frac{1}{6}*30[/tex] = 5
Hence,
Number of black counters = 5
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]

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

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

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]
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)
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]
