Part B: Your cell phone and tablet use the same account. The cell phone costs $0.10 for
each minute of use and the tablet costs $0.15 for every minute of use. Each month, you
want to only spend up to $450 and use Tess than 5,000 minutes on both of the devices.
Now, create a system of inequalities using the above information (use x and y as the
variables).
pls help for brainliest
The inequalities are x + y < 5000 and 0.10x + 0.15y ≤ $450 which shows each month, you want to only spend up to $450 and use less than 5,000 minutes on both of the devices.
What is inequality?Inequality is defined as a mathematical expression in which both sides are not equal and have mathematical signs that are either less than or greater than.
Let's suppose the total minutes of uses for cell phone is x
and total minutes of uses of for tablet is y
Cell phone cost $0.10 each minute and tablet cost $0.15 each minute.
Then total minutes will be:
x + y < 5000 (as it is given that the time will be less than 5,000 minutes on both of the devices)
And total cost = $450
0.10x + 0.15y ≤ $450
Thus, the inequalities are x + y < 5000 and 0.10x + 0.15y ≤ $450 which shows each month, you want to only spend up to $450 and use less than 5,000 minutes on both of the devices.

IQR for males: 3
IQR for females: 2
Q1 for males: 5
Q1 for females: 6
the number of females who spend over 6 hours exercising is greater(?) than the number of males who spent 6 hours exercising
Step-by-step explanation:
An equal amount of men and women were randomly selected and asked how many hours per week they spend excercising
How to find IQR?to find IQR you have to identify your median(middle value) of the lower and upper half of the data. These are called quartile 1(Q1) and quartile 3(Q3). You subtract these two (Q3 and Q1) and the IQR is the difference.
Males box plot:
Minimum: 1
Maximum: 10
Q1: 5
Q2: 7
Q3: 8
Subtract Q3 and Q1
8 - 5 = 3
This is the IQR
Females box plot:
Minimum: 4
Maximum: 10
Q1: 6
Q2: 7
Q3: 8
Subtract Q3 and Q1
8 - 6 = 2
IQR =2

If x and y vary inversely and x = -9 when y = -30, what is the constant of variation
Answer:
270
Step-by-step explanation:
x = k/y This is an inverse relationship with k = constant of proportion (or variation)
-9 = k/(-30)
k = -9 * -30 = 270
Answer:
Constant of variation = 270.
Step-by-step explanation:
y = k/x
-30 = k / -9
k = -30 * -9
k = 270

Answer:
Step-by-step explanation:
An empty lorry weighs 3500kg. It weighs 7250 kg when loaded with 50 bags of coffee .What is the average mass of each bag ?
Answer:
The average mass of one coffee bag is 75kg.
Step-by-step explanation:
The lorry on its own weighs 3500kg.
If it weighs 7250kg alongside coffee bags, we can make the assumption that to find the total mass of the coffee bags, we must take the combined total and subtract the lorry's weight from it.
7250kg subtract 3500kg is 3750kg.
There are 50 coffee bags, so this is the mass of all 50.
If we want to find the mass of one coffee bag, we have to divide the mass of 50 coffee bags by 50.
3750kg divided by 50 is 75kg.
The average mass of one coffee bag is 75kg.

The radius of the surface of the water in the tank is increasing at a rate of 0.25m/min. at what rate is the area of the surface changing when the radius is 1.2m?
Answer:
1.88 m^2/min to the nearest hundredth.
Step-by-step explanation:
Area = π r^2
Using Calculus notation:
dA/dr = 2π r
dr/dt = 0.25 (given)
So the rate of change of area
dA/dt = dA/dr * dr/dt
So when r = 1.2
dA/dt = 2 π * 1.2 * 0.25
= 0.6π m^2/min.
= 1.88 m^2/min to the nearest hundredth.

Consider the line shown on the graph. Enter the
equation of the line in the form y = mx + b where m is
the slope and b is the y-intercept.
y=
From the graph, we concluded that line passes through the points (0, 3) and (1, 4) respectively.
So, slope of the line (m) passing through the points (a, b) and (c, d) is
m = d - b/ c - a
So, on substituting the values, we getm = 4 - 3 / 1 - 0 = 1/1 = 1
Also, line makes an intercept of 3 units in positive direction of y - axis.
So, c = 3
So, Equation of line is given byy = mx + c
y = 1 × x + 3
y = x + 3Alternative Method :-We know, Equation of line passing through the points (a,b) and (c, d) is given by
y - b = d - b / c - a (x - a)
Here,a = 0
b = 3
c = 1
d = 4
So, on substituting these values in above result, we get :-y - 3 = 4 - 3 /1 - 0 ( x - 0 )
y - 3 = 1/1 ( x - 0 )
y - 3 = x
y = x + 3Different forms of equations of a straight line :-1. Equations of horizontal and vertical lines
Equation of line parallel to x - axis passes through the point (a, b) is y = b.
Equation of line parallel to y - axis passes through the point (a, b) is x = a.
2. Point-slope form equation of lineEquation of line passing through the point (a, b) having slope m isy - b = m(x - a)
3. Slope-intercept form equation of lineEquation of line which makes an intercept of c units on y axis and having slope m is y = mx + c.
4. Intercept Form of LineEquation of line which makes an intercept of a and b units on x - axis and y axis respectively is x/a + y/b = 1.
5. Normal form of LineEquation of line which is at a distance of p units from the origin and perpendicular makes an angle B with the positive X-axis is x cosB + y sinB = p.
Does anybody know this? I got told it was 828.8 by someone and it was wrong.Find the surface area of the square pyranid
Answer:
800 ft²
Step-by-step explanation:
The total surface area of a square-base pyramid is given by the formula ...
A = s(s +2h) . . . . . . where s is the side length, h is the face slant height
In this problem, we need to find the slant height of a face in order to use this formula.
__
slant heightThe distance from the middle of one edge of the base to the peak of the pyramid is the slant height of a face of the pyramid. It is the hypotenuse of a right triangle whose legs are the pyramid height, and half the width of the base. For this pyramid, that is a right triangle with legs 15 and 8.
The Pythagorean theorem is used to find the hypotenuse of that triangle:
c² = a² +b² . . . . square of hypotenuse = sum of squares of legs
c² = 15² +8² = 225 +64 = 289
c = √289 = 17
The slant height of a face of the pyramid is 17 ft.
total areaThe area formula tells us the total surface area is ...
A = s(s +2h)
A = (16 ft)(16 ft + 2×17 ft) = (16 ft)(50 ft)
A = 800 ft²
The total surface area is 800 square feet.
The scatterplot that represents the monthly values of stock QRS has an r-
value of -0.993. Which best describes the correlation of the graph?
OA. Weak correlation
B. Strong positive correlation
C. Strong negative correlation
OD. No correlation
Answer:
C
Step-by-step explanation:
Because it's a negative, then we could assume that it is a negative correlation. And because it's closer to -1, it is a strong negative correlation.
The value -0.993 is Strong Negative correlation.
What is Coefficient Correlation?The strength and direction of two variables in a scatterplot are quantified by the correlation coefficient, or r value. It goes from one to one.
A perfect positive correlation is denoted by +1.A perfect negative correlation is denoted by -1.0 indicates a lack of associationSo, the value close to 1 is Strong positive correlation and close to -1 is Strong Negative correlation.
Thus, -0.993 close to -1 is Strong Negative correlation.

Answer:
p(x) = x⁴ -7x³ +59x² -343x +490
Step-by-step explanation:
Each root is the zero of a binomial factor. That is, for root x = a, the polynomial has a factor (x -a). Complex roots come in conjugate pairs, so if there is a root 7i, there is also a root -7i.
__
The given roots mean the polynomial can be written in factored form as ...
p(x) = (x -2)(x -5)(x -7i)(x -(-7i))
We can combine multiply these factors together to simplify the polynomial.
p(x) = (x² -7x +10)(x² +49)
p(x) = x⁴ -7x³ +59x² -343x +490
_____
Additional comment
Combining the conjugate complex roots uses the special form for the factoring of the difference of squares.
a² -b² = (a -b)(a +b)
(x -7i)(x +7i) = x² -(7i)² = x² -49i² = x² +49 . . . . . where i = √(-1)
