Given that;
Speed of car travelling = 57 mph
Find:
Distance cover in feet in one minute
Distance cover in feet in one second
Computation:
1 mile = 5280 feetSpeed of car travelling = 57 mph
Speed of car travelling in feet = 57 × 5280
Speed of car travelling in feet = 300,960 feet per hour
Distance cover in feet in one minute = 1 × [300,960 / 60]
Distance cover in feet in one minute = 5,016 feet
Distance cover in feet in one second = 1 × [5016 / 60]

Florence buys a model railroad set priced at $57. Shipping and handling are an additional 30% of the price. How much shipping and handling will Florence pay? $
Answer:
[tex]74.1[/tex]$
Step-by-step explanation:
[tex] \frac{x}{57} = \frac{30}{100} [/tex]
[tex](x)100 = (30)57[/tex]
[tex](x)100 = 1710[/tex]
[tex] \frac{(x)100}{100} = \frac{1710}{100} [/tex]

Let the number of games, x, and the number of rides y, For 2x + 4y = 20, what is the slope of the graph? What is the slope? (Hint: Solve for y) Write the y-intercept as an ordered pair? (Hint: x=0 at the y-intercept) 10 Write the x-intercept as an ordered pair? (Hint: y = 0 at the x-intercept)
Answer:
m= -1/2, (0,5), (10,0)
Step-by-step explanation:
Let us write it in slope intercept form, y=mx +b where m is the slope:
2x+4y=20
4y= -2x+20
y= -1/2x+5
Therefore, the slope is -1/2
The y intercept can be found when we substitue 0 as x.
y= -1/2*0 +5
y=0+5
y=5
(0,5)
The x intercept can be found when we substitute 0 as y.
0=-1/2x+5
-5 =-1/2x
x= 10
(10, 0)

Simon borrowed $1,000 for 3 years at 5% compound interest rate. How much did he owe after 3 years? Enter your numeric answer, (without the $ sign), to the nearest cent below
Answer:
Total amount after 3 year = 1,157.625
Step-by-step explanation:
Given:
Amount deposit P = $1,000
Number of year n = 3 year
Interest rate r = 5% = 0.05
Find:
Total amount after 3 year
Computation:
Amount = P[1+r]ⁿ
Total amount after 3 year = 1,000[1+0.05]³
Total amount after 3 year = 1,000[1.05]³
Total amount after 3 year = 1,157.625

12)If p and p' are the length of the perpendiculars drawn from the points (+-root a2-b2,0) to the line x/a cosA + y/b sinA = 1, prove that: p x p' = b2.
Answer:
Kindly refer to below explanation.
Step-by-step explanation:
Given equation of line:
[tex]\dfrac{x}{a}cos\theta+ \dfrac{y}{b}sin\theta =1\\OR\\\dfrac{x}{a}cos\theta+ \dfrac{y}{b}sin\theta-1=0[/tex]
Given points are:
[tex](\sqrt{a^2-b^2},0), (-\sqrt{a^2-b^2},0)[/tex]
Formula for distance between a point and a line is:
If the point is [tex](m, n)[/tex] and equation of line is [tex]Ax+By+C = 0[/tex]
Then, perpendicular distance between line and points is:
[tex]Distance = \dfrac{|Am+Bn+C|}{\sqrt{A^2+B^2}}[/tex]
Here,
[tex]A = \dfrac{x}{a}cos\theta\\B = \dfrac{y}{b}sin\theta\\C = -1[/tex]
For the first point:
[tex]m = \sqrt{a^2-b^2}, n = 0[/tex]
By the above formula:
[tex]p[/tex] and [tex]p'[/tex] can be calculated as:
[tex]p\times p' =\\\Rightarrow \dfrac{|\dfrac{cos\theta}{a}\times \sqrt{a^2-b^2}+ 0 -1|}{\sqrt{\dfrac{cos^2\theta}{a^2}+\dfrac{sin^2\theta}{b^2}}}\times \dfrac{|-\dfrac{cos\theta}{a}\times \sqrt{a^2-b^2}+ 0 -1|}{\sqrt{\dfrac{cos^2\theta}{a^2}+\dfrac{sin^2\theta}{b^2}}}\\\Rightarrow \dfrac{1-(\sqrt{a^2-b^2}\times \frac{cos\theta}{a})^2}{\dfrac{cos^2\theta}{a^2}+\dfrac{sin^2\theta}{b^2}}}[/tex]
Formula used:
[tex](x+y)(x-y) = x^2 - y^2[/tex]
[tex]\Rightarrow \dfrac{\dfrac{a^2-a^2cos^2\theta+b^2cos^2\theta}{a^2}}{\dfrac{b^2cos^2\theta+a^2sin^2\theta}{a^2b^2}}\\\Rightarrow b^2(\dfrac{a^2sin^2\theta+b^2cos^2\theta}{a^2sin^2\theta+b^2cos^2\theta})\\\Rightarrow b^2[/tex]
(Using the identity:
[tex]sin^2\theta +cos^2\theta = 1[/tex])
(Hence provded)

What is the solution to this equation? 5(x - 6) + 4 = 7x - 4
5(x - 6) + 4 = 7x - 4
5x - 30 + 4 = 7x - 4
5x - 26 = 7x - 4
5x - 26 + 4 = 7x
5x - 22 = 7x
-22 = 7x - 5x
-22 = 2x
-22 / 2 = x
-11 = x
x = -11 is the solution to the given equation

Answer:
it would cost $34.50 to purchase 7.5 lbs of walnuts.
Answer:
$34.50
Step-by-step explanation:
First find out how much 1/4 of a lb will cost.
3.45/3= 1.15
This is the cost for only 1/4 a lbs of chopped walnuts. Take this number and multiply it by 4 to find how much it would cost for 1 whole pound of walnuts.
1.15x4= 4.60
It costs $4.60 for a whole pound of walnuts. If you are trying to find how much it costs for 7.5 lbs, then multiply 4.60 by 7.5.
4.60x7.5= 34.5
For 7.5 lbs of walnuts will cost $34.50

-6x-1=23
=> -6x=1+23
=> -6x=24
=> x= 24/-6
=> x= -4
Hope it helps!
Step-by-step explanation:
Hey there!
Given;
[tex] - 6x - 1 = 23[/tex]
~ Shift "-1" on right side.
[tex] - 6x = 23 + 1[/tex]
[tex] - 6x = 24[/tex]
~Divide 24 by -6.
[tex]x = \frac{24}{ - 6} [/tex]
Therefore, x= -4.

A social media website had 100,000 followers its first year. The number of followers increased by 9% each year. Write an exponential growth function to represent this situation
Answer:
an exponential growth function to represent this situation is:
[tex]x\left(t\right)=100,000\times \left(1.09\right)^t\:[/tex]
Step-by-step explanation:
We know that the exponential growth function is of the form
[tex]x\left(t\right)\:=\:x_0\:\times \:\left(1\:+\:r\right)^t[/tex]
where
x(t) represents the value at time tx₀ represents the initial value at time t = 0. In other words, it is the initial value (the amount before measuring growth or decay)r represents the growth factor when r > 0 and decay factor when r < 0t represents the of time intervals that have passedIn our case,
Given that
A social media website had 100,000 followers its first year. Thus,
x₀ = 100,000The number of followers increased by 9% each year. Thus,
r = 9% = 0.09Thus, substituting r = 0.09 and x₀ = 100,000 in the growth function
[tex]x\left(t\right)\:=\:x_0\:\times \:\left(1\:+\:r\right)^t[/tex]
[tex]x\left(t\right)=100,000\times \left(1+0.09\right)^t\:[/tex]
[tex]x\left(t\right)=100,000\times \left(1.09\right)^t\:[/tex]
Therefore, an exponential growth function to represent this situation is:
[tex]x\left(t\right)=100,000\times \left(1.09\right)^t\:[/tex]

Martha wants to build a rectangular wooden border around the perimeter of her children's playground. She can find the perimeter by using the formula 2w + 2l. The length, l, is 12 feet and the width, w, is 10 feet. What is the perimeter of Martha's wooden border?
Answer: The perimeter of Martha's wooden border = 44 feet.
Step-by-step explanation:
Given: The formula to find the perimeter = 2w + 2l. , where w = width and l = length
If l= 12 feet and w = 10 feet
Then, the perimeter of Martha's wooden border = 2(10)+2 (12) feet
The perimeter of Martha's wooden border = 20+24 feet
The perimeter of Martha's wooden border = 44 feet
Therefore, the perimeter of Martha's wooden border = 44 feet.

Lee is making scarfs for a shelter. He purchased 11 skeins of yarn. Each skein has 660 feet of yarn. He needs 200 yards of yarn to make one scarf. How many scarfs can lee make for the shelter
Answer:
12
Step-by-step explanation:
skeins of yarn purchased = 11
Feets per skein = 660 feets
Total number of feets purchased = (11 * 660) = 7260 feets
To make a scarf :
1 scarf = 200 yards
Recall :
1 yard = 3 feets
Hence,
1 scarf = (200 *3) = 600 feets
Number of scarf that can be made :
Total feets of yarn / Number of feets per scarf
= 7260 / 600
= 12.1
Hence, number of scarfLee can make for shelter is 12 (nearest whole number)
