What is the perimeter of 10 ft long and 9 feet wide?
Answer: Answer is 38ft.
Step-by-step explanation: The figure that measures 10ft by 9ft is a rectangle which means two sides measure 10ft each (length) and two sides measure 9ft each (width). A perimeter simply measures all sides of the entire shape, that is;
10ft + 9ft + 10ft + 9ft = 38ft.
Bob bought 24 hockey tickets for $83. Adult tickets cost $5.50 and child tickets cost $2.00. How many child tickets did he buy?
Answer:
Step-by-step explanation:
a + c = 24......a = 24 - c
5.5a + 2c = 83
5.5(24 - c) + 2c = 83
132 - 5.5c + 2c = 83
-5.5c + 2c = 83 - 132
-3.5c = - 49
c = -49 / -3.5
c = 14 <==== 14 child tickets
a + c = 24
a + 14 = 24
a = 24 - 14
a = 10 ........and 10 adult tickets

Which absolute value expression represents the distance between 3 and - 2 on a number line?
Answer:
|3 - (-2) |, or|-2 - 3|Both are equivalent.
Explanation:
The distance between two numbers in a number line is the absolute value of the difference between the two numbers.
Thus, the distance between a number x and a number y is |x - y|, which is also equivalent to |y - x|.
In this case the distance between 3 and - 2 can be represented by either of the expressions:
|3 - (-2) |, or|-2 - 3|Note that when you simplify them you get the same value:

Solve this exercise using the fact that the sum of the measures of the three angles of a triangle is 180degrees°.
In a triangle, the measures of the three angles are x, x+14, and x−38. What is the measure of each angle
Answer:
68°, 82°, and 30°
Step-by-step explanation:
x+x+14+x-38=180
combine like terms
3x-24=180
put variables on one side
3x=204
divide
x=68
substitute
x=68
x+14=82
x-38=30
By using the triangle angle sum theorem, we find that the measures of the angles of the triangle in question are 68 degrees, 82 degrees, and 30 degrees.
Explanation:This question involves using the fact that the sum of internal angles in any triangle totals 180 degrees. In this triangle, the three angles are given as x, x+14, and x-38. To find the measures of these angles, we set up the below equation:
x + (x+14) + (x−38) = 180
The step above incorporates the triangle angle sum theorem. Now we simplify and solve for 'x':
3x - 24 = 180
3x = 204
x = 68
So the measure of the angles in the triangle are 68 degrees, 82 degrees, and 30 degrees.

Line b passes through the Point(-3, -4) and has a slope of -1/2. What is the equation of Line b in standard form?
x + 2y = -11
x + 2y = -10
2x + y = -11
2x + y = -10
Answer:
[tex]x+2y=-11[/tex]
Step-by-step explanation:
Slope intercept form of a line is given by:
[tex]y=mx+b[/tex]
Where
m is the slope and b is the y-intercept
Given slope is [tex]-\frac{1}{2}[/tex]
We can write:
[tex]y=-\frac{1}{2}x+b[/tex]
Now to find b, we replace x with -3 and y with -4, given, so we have:
[tex]y=-\frac{1}{2}x+b\\-4=-\frac{1}{2}(-3)+b\\-4=\frac{3}{2}+b\\b=-5.5[/tex]
So, the equation is:
[tex]y=-\frac{1}{2}x-\frac{11}{2}[/tex]
Now,
The standard form is given by:
[tex]Ax+By=C[/tex]
So, we take x and y to left side and the constant to right side. Rearranging, we get:
[tex]y=-\frac{1}{2}x-\frac{11}{2}\\2y=-x-11\\x+2y=-11[/tex]
The first answer choice is right.
Final answer:
The equation of line b that passes through the point (-3, -4) and has a slope of -1/2 in standard form is x + 2y = -11.
Explanation:
To find the equation of line b that passes through the point (-3, -4) and has a slope of -1/2, we will start with the slope-intercept form of a line equation y = mx + b, where m is the slope and b is the y-intercept. While we know the slope (-1/2), we do not yet have the y-intercept. We can use the given point to solve for b. Plugging the point into the equation gives -4 = (-1/2)(-3) + b, which simplifies to -4 = 3/2 + b. Solving for b yields b = -11/2.
Now we have the slope-intercept form of the line: y = (-1/2)x - 11/2. To convert this to standard form, which is Ax + By = C, we multiply through by 2 to clear the fractions, which gives us 2y = -x - 11. Rearranging this, we add x to both sides to get x + 2y = -11. Therefore the correct equation in standard form is x + 2y = -11.

At the grocery store, Lily spent $m$ dollars on milk, twice that amount on fruit, and $6$ dollars less than $3$ times the amount spent on milk for bread. If she entered the store with $\$80$, how much money did she have when she left? Write your answer in terms of $m$.
Answer:
$remaining=86-6m
Step-by-step explanation:
$remaining = 80 - (m + 2m) - (3m-6)
$remaining = 80 - 3m - 3m +6
$remaining = 86 - 6m
80 -> total amount she brings into the store
m -> money spent on milk
2m -> money spent on fruit (two x m)
3m-6 -> bread (six dollars less than three times the milk value)
Simplify and the result is 86-6m

A rocket is dropping to the moons surface at a constant rate of 15 feet per second. After 2 minutes of descent the rocket is at a height of 11,400 feet above the moons surface. At what elevation in feet was the rocket when it started to drop to the moons surface?
Answer:
13,200 feet
Step-by-step explanation:
So, the rocket starts descending at a given rate and time, so we first need to find the length it passed during that descent.
Length equals to speed multiplied with time:
s = v • t
since speed is given in feet per second, we need to convert minutes to seconds; if one minute has 60 seconds, then two minutes have 120 seconds.
s = 15 feet/s • 120 s
s = 1800 feet
So, the rocket descended 1800 feet, but it still has 11,400 feet to the Moon's surface. That means that the rocket was on 11,400 + 1,800 = 13,200 feet elevation when it started to drop.

What is the fraction
Answer: 2 1/6
Step-by-step explanation:
Because the denominators are different, and there are whole numbers involved, then first make the fractions improper.
4 1/2 -> 9/2
6 2/3 -> 20/3
Next, make the denominators the same by multiplying each fraction by the denominator of the other.
9/2 * 3 = 27/6
20/3 * 2 = 40/6
Then you can subtract the numerators because the denominators are the same:
40/6-27/6= 13/6
Then you can convert to a mixed fraction if need be.

P=v/1+kM^-t solve for k
Answer: [tex]k=\frac{M^t(v-P)}{P}[/tex]
Step-by-step explanation:
Given the following equation provided in the exercise:
[tex]P=\frac{v}{1+kM^{-t}}[/tex]
You can follow these steps in order to solve for "k":
1. You must multiply both sides of the equation by [tex]1+kM^{-t}[/tex]:
[tex](P)(1+kM^{-t})=(\frac{v}{1+kM^{-t}})(1+kM^{-t})\\\\P+PkM^{-t}=v[/tex]
2. The next step is to subtract "P" from both sides of the equation:
[tex]P+PkM^{-t}-(P)=v-(P)\\\\PkM^{-t}=v-P[/tex]
3. Now apply the Negative Exponent Rule, which states that:
[tex]a^{-n}=\frac{1}{a^n}[/tex]
Then:
[tex]\frac{Pk}{M^{t}}=v-P[/tex]
4. Multiply both sides of the equation by [tex]M^t[/tex]:
[tex](M^t)(\frac{Pk}{M^{t}})=(M^t)(v-P)\\\\Pk=M^t(v-P)[/tex]
5. And finally, you must divide both sides of the equation by "P":
[tex]\frac{Pk}P=\frac{M^t(v-P)}{P}\\\\k=\frac{M^t(v-P)}{P}[/tex]

Write a minor function for the line with the slope of -5 that passes through points (7,3)
The equation of the line is [tex]5x+y-38=0[/tex]
Step-by-step explanation:
The slope is [tex]m=-5[/tex]
Also, the line passes through the points [tex](7,3)[/tex]
To find a line with slope [tex]m=-5[/tex] that passes through the points [tex](7,3)[/tex], let us use the equation of a line with slope that passes through the point is given by [tex](y-y_{1} )=m(x-x_{1} )[/tex] where m is the slope and [tex](x_{1} ,y_{1} )[/tex] are the points [tex](7,3)[/tex].
Thus, substituting the values in the equation of a line, we get,
[tex](y-3)=-5(x-7)[/tex]
Multiplying the term [tex](x-7)[/tex] by -5, we get,
[tex]y-3=-5 x+35[/tex]
Adding both sides by 5x,
[tex]5x+y-3=35[/tex]
Subtracting 35 from both sides of the equation,
[tex]5x+y-38=0[/tex]
Thus, the equation of the line is [tex]5x+y-38=0[/tex]
