Austin exercises more than 35 minutes per day. Use t to represent Austin's amount of exercise (in minutes per day).
Answer:
The number of minutes Austin exercises is t > 35 minutes/day
Step-by-step explanation:
The number of minutes Austin exercises each day can be expresses as an inequality, which defines a region of feasible values within a range of values.
The number of minutes Austin exercises each day > 35 minutes
Let t represent the number of minutes Austin exercises, we can write;
The number of minutes Austin exercises is t > 35 minutes/day
Answer:

Which equation is represented by the table?
Answer:
D. 3x - 1
Step-by-step explanation:
y = mx + b
We see the point (0, -1), so b = -1
y = mx - 1
We can find the slope using 2 points such as (0, -1) and (1, 2).
m = (2 - (-1))/(1 - 0) = 3
y = 3x - 1
Answer: D. 3x - 1
A glider flies 13 miles north from the airport and then 24 miles diagonally southeast. Approximately how far west does the glider have to fly to return to the airport?
Answer:
20.2 miles
Step-by-step explanation:
This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:
[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
[tex]/24/^{2}[/tex] = [tex]/x/^{2}[/tex] + [tex]/13/^{2}[/tex]
576 = [tex]x^{2}[/tex] + 169
[tex]x^{2}[/tex] = 576 - 169
= 407
x = [tex]\sqrt{407}[/tex]
= 20.1742
x = 20.2 miles
The glider has to fly 20.2 miles to return to the airport.

if the diameter of the concentric circles as shown in the given figure are in the ratio 1:2:3 then find the ratio of the areas of three regions
Answer:
1 : 4 : 9
Step-by-step explanation:
Given the ratio of diameters = a : b , then
ratio of areas = a² : b²
Here ratio of diameters = 1 : 2 : 3 , so
ratio of areas = 1² : 2² : 3² = 1 : 4 : 9

An ice cream factory makes 220 quarts of ice cream in 5 hours. How many
quarts could be made in 48 hours? What was that rate per day?
Answer:
2112 quarts in 48 hr
1056 quarts made per day
Step-by-step explanation:
to find out how many quarts in one hour divide 220 by 5
220÷5=44
then multiply by 24 to know how much quarts made per day
44×24=1056
then multiply by two to know how many quarts in 48 hours
1056×2=2112
A right triangle has legs of 18 inches and 24 inches whose sides are
changing. The short leg is increasing by 4 in/sec and the long leg is
shrinking at 9 in/sec. What is the rate of change of the hypotenuse?
Given:
A right triangle has legs of 18 inches and 24 inches.
The short leg is increasing by 4 in/sec and the long leg is shrinking at 9 in/sec.
To find:
The rate of change of the hypotenuse.
Solution:
Let x be the shorter leg (Base), y be the larger leg (Perpendicular) and z be the hypotenuse.
We have,
[tex]\dfrac{dx}{dt}=4\text{ in/sec}[/tex]
[tex]\dfrac{dy}{dt}=-9\text{ in/sec}[/tex]
[tex]x=18[/tex]
[tex]y=24[/tex]
According to the Pythagoras theorem,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
[tex]z^2=x^2+y^2[/tex] ...(i)
[tex]z^2=(18)^2+(24)^2[/tex]
[tex]z^2=324+576[/tex]
[tex]z^2=900[/tex]
Taking square root on both sides.
[tex]z=\pm \sqrt{900}[/tex]
Side cannot be negative. So,
[tex]z=30[/tex]
Differentiating (i) with respect to time t, we get
[tex]\dfrac{d}{dt}z^2=\dfrac{d}{dt}(x^2+y^2)[/tex]
[tex]2z\dfrac{dz}{dt}=2x\dfrac{dx}{dt}+2y\dfrac{dy}{dt}[/tex]
[tex]2(30)\dfrac{dz}{dt}=2(18)(4)+2(24)(-9)[/tex]
[tex]60\dfrac{dz}{dt}=144-432[/tex]
[tex]60\dfrac{dz}{dt}=-288[/tex]
Divide both sides by 60.
[tex]\dfrac{dz}{dt}=\dfrac{-288}{60}[/tex]
[tex]\dfrac{dz}{dt}=-4.8[/tex]
Here, negative sign means hypotenuse is decreasing.
Therefore, the hypotenuse is shrinking at 4.8 in/sec.

1) The equation y = 3.5x represents the relationship between 2, the number of pounds of fruit,
and y, the price.
• Which ordered pairs represent an amount of fruit and the corresponding
price in the given equation? Choose ALL that apply.
(4, 14)
(6,9.5) (8,28)
(9.5,6)
(14,4)
(28,8)
Answer:
(4,14)
Step-by-step explanation:
plug in ordered pairs for the given equation and see which one works. ordered pairs are simply (x,y) and the equation just so happens to have x and y variables. when x in the equation equals 4 then 3.5*4 is equal to 14 which is the y value of the first ordered pair. try it with the others and they don't work. is x equaled 28 then 3.5*28 is 98 and that paired y is only 8 so no. do it with all ordered pairs if you must. it's an elimination game
The ordered pairs (4, 14), and (3, 28) satisfy the equation y = 3.5x.
What is an ordered pair?An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.
Pair in Order = (x,y)
x is the abscissa, the distance measure of a point from the primary axis x
y is the ordinate, the distance measure of a point from the secondary axis y
The given equation for the pounds of fruits 'x' and the total cost 'y' is,
y = 3.5x.
Now, The ordered pairs that satisfy the equation can be obtained by putting the value of 'x' and checking the corresponding 'y' value.
(4, 14).
y = 3.5×4.
y = 14. (satisfies).
Similarly,
(3, 28), also satisfies the equation y = 3.5x.

How many solutions does the system have?
x + y = 5
x + y = 6
- none
- one
- two
- infinite
Answer: no solution
Step-by-step explanation:
Answer:
no solutions
Step-by-step explanation:
In order for the system to have solutions, x and y must work for both equations.
The easiest way to solve this is the isolate the y variable on both equations and then solve for x:
1. x+y=5
y=5-x
2. x+y=6
y=6-x
Since the y variables for both equations should be the same, let us make a new equation:
6-x=5-x
6=5
Hmm... This doesn't seem to work! 6 does not equal to 5. Therefore, there are no solutions.
