Answer:
They will hit 180 seconds in 118.6 year
Step-by-step explanation:
Let M be the record for the mile (in seconds)
Let x be the year after 1958
So, x=(year)-19548
We are given that In the half-century since then, the record has decreased by 0.5 seconds per year
So, slope = m = 0.5
Now we will use point slope form
y = mx+c
So, we can express M as,
[tex]M=239.3-0.5 \times x[/tex]
Now we are supposed to find when they will hit 180 seconds
Substitute M = 180 in equation
180=239.3-0.5x
x=118.6
So, they will hit 180 seconds in 118.6 year

A 7-day cruise is 15% off the regular price of $1,800. How much is the discount?
Answer:
The discount is $270
The new price would be $1,530
Step-by-step explanation:
You just multiply 1800 times 0.15 to get how much the discount would be and then if you are trying to find the new price you would subtract the discount or multiply 1800 times 0.85 because 100-15 is 85.

flip the sign when dividing by a negative number
6>x is the answer.
Answer:
[tex]\boxed { x < 6}[/tex]
Step-by-step explanation:
Solve the following inequality:
[tex]-6 < 3x - 4x[/tex]
-Combine like terms:
[tex]-6 < 3x - 4x[/tex]
[tex]-6 < -x[/tex]
-Switch sides:
[tex]-6 < -x[/tex]
[tex]-x > -6[/tex]
-When you are dividing an integer by a negative integer, then the inequality sign would change. So, to get the variable [tex]x[/tex] positive, divide both sides by [tex]-1[/tex]:
[tex]\frac{-x}{-1} > \frac{-6}{-x}[/tex]

There are 3 consecutive integers. If the smallest one is n, find the sum of 3 integers.
Answer:
3n + 3Step-by-step explanation:
The consecutive integers are increasing by 1
n ← the smallest integer

n+1+1 = n+2 ← the largest integer
The sum:
S = n + n+1 + n+2
S = 3n + 3

Akiko wants to fence in her [tex]12[/tex] ft by [tex]10[/tex] ft vegetable garden. There will be a path [tex]x[/tex] ft wide between the garden and the fence. The area to be enclosed by the fence will be [tex]360[/tex] sq ft. Write a quadratic function that can be used to determine the value of [tex]x[/tex].
Answer:
see below
Step-by-step explanation:
The length is 12 + 2x and the width is 10 + 2x
A = l*w
360 = ( 12+2x) ( 10+2x)
FOIL
360 = 120 + 24x+20x + 4x^2
Combine like terms
360 = 4x^2 +44x+120
Subtract 360 from each side
0 = 4x^2 +44x +120-360
0 = 4x^2+ 44x -240
For fun, lets solve
0 = 4( x^2 + 11x - 60)
0 = 4( x+15) ( x-4)
Using the zero product property
x= -15 x=4
Since we cannot have negative length
x=4 ft
Answer:
[tex]x^2+11x-60=0[/tex]
Step-by-step explanation:
Refer to the drawing.
We know that the area enclosed by the fence is 360 square feet. Remember that the area for a rectangle is given by the following formula:
[tex]A=bh[/tex]
So, let's substitute 360 for A, (12+2x) for b, and (10+2x) for h. This yields:
[tex]360=(12+2x)(10+2x)[/tex]
We can simplify this. On the right, factor out a 2 from the first term and a 2 from the second. This yields:
[tex]360=2(6+x)\cdot2(5+x)[/tex]
Multiply:
[tex]360=4(x+6)(x+5)[/tex]
Divide both sides by 4:
[tex]90=(x+6)(x+5)[/tex]
Multiply on the right:
[tex]90=x^2+6x+5x+30[/tex]
Add on the right:
[tex]90=x^2+11x+30[/tex]
Subtract 90 from both sides. So, our equation is:
[tex]x^2+11x-60=0[/tex]
And we're done!
I can buy 3 cans of soda for $1.05. How many cans can buy at the same rate for $21?
Answer:
20 cans
Step-by-step explanation:
Divide $21 by $1.05 and you get 20.
Answer:
60 cans of soda
Step-by-step explanation:
3 cans of soda for $1.05
$21 = ? cans of soda
21 / 1.05 = 20
so if 20 $1.05's fit in $21 then how many cans fit in $21
20 x 3 = 60
you can buy 60 cans of soda with $21

put the variables to one side and numbers to the other side
then divide 4 from each side
now you have the answer
Answer: -9
Step-by-step explanation:
To solve the equation, isolate the variable, then use basic arithmetic.
Subtract 4x on both sides to obtain the equation:
-12 = 4x + 24
Subtract 24 on both sides to isolate 4x, and obtain the equation:
-36 = 4x
Finally, divide both sides by 4 to obtain the following:
-9 = x

For the points A(-3, 2), B(-3, 7), and C(2, 7), find the equation of the line
through B perpendicular to line AC.
Answer:
The equation of the line perpendicular to AC and passing through point B is y = -x + 4
Step-by-step explanation:
We start by finding the slope and equation of line AC
The equation of a straight line can be given as;
y = mx + c
where m is the slope and c is the y-intercept
Mathematically, the slope is given as;
m = (y2-y1)/(x2-x1)
m = (7-2)/(2-(-3)) = 5/5 = 1
So the equation becomes ;
y = x + c
We only need the slope since we are trying to get another line perpendicular to this
If two lines are perpendicular, then the product of the slopes of both lines is equal to -1
This means that m1 * m2 = -1
So this means that the slope of the perpendicular line is -1/1 = -1
Thus, the equation of the line we are finding would be;
y = -x + c
since it passes through line B, we can make a substitution of the coordinates of point B
That would be;
7 = -(-3) + c
7 = 3 + c
c = 7-3
c = 4
So the equation of that line is;
y = -x + 4 or simply y = 4-x
