A phone call costs $0.65 for the first 3 minutes and $0.15 for each additional minute. If the total charge for the call
was $5.00, how many minutes was the call?
Answer:
31 Minutes
Step-by-step explanation:
4.78 = 0.15 + 0.58
0.15m = 4.78 - 0.58
m = 4.78 - 0.58 divided by 0.15 = 28 minutes
So in total we have 28 + 3 = 31 minutes
What would be the mass of a 10kg suitcase on Neptune?
The acceleration due to gravity on the surface of the Moon is about 1.625 m/s2. So, an object the mass of 10 kg. will weigh 10 × 1.625 = 16.25 N (newton) on the moon.
The mass will be 16.25 Kg
what is acceleration due to gravity?Acceleration due to gravity is the acceleration gained by an object due to gravitational force. Its SI unit is m/s2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.
Gravity is the force with which the earth attracts a body towards its centre. Let us consider two bodies of masses ma and mb. Under the application of equal forces on two bodies, the force in terms of mass is given by:
mb = ma [aA/aB] this is called an inertial mass of a body.
Given:
mass of object = 10 kg
Acceleration due to gravity on Moon
=1.625 m/s²
So,
Mass of object on moon= 1.625 * 10 = 16.25 Kg

3(x - 5) = 30
I dont know how to solve this
Answer:
x=15
Step-by-step explanation:
3(x-5)=30
First, you would distribute the three to the x and the negative five.
3x-15=30
Then you would add 15 to the 15 to cancel it and to the 30 to make it even.
3x-15=30
+15=+15=
3x=45
Finally, you would divide 3 into both sides, cancelling out the three and fiving you,
x=15
Hope this helped!
Start by distributing the 3 through the parenthses on the left side.
This gives us 3x - 15 = 30.
Now add 15 to both sides to end up with 3x = 45.
Dividing both sides by 3, we fin that x = 15.

Three times a number decreased by the sum of seven times the number and 12 is equal to twice the difference of the number and 3
Answer:
x = -1
Step-by-step explanation:
3x - (7x +12) = 2(x - 3)
3x - 7x - 12 = 2x - 6
-4x - 12 = 2x - 6
-12 = 6x - 6
-6 = 6x
x = -1
Check:
-1(3) - (-1(7) + 12) = 2(-1 - 3)
-3 - (-7 + 12) = -2 - 6
-3 - (5) = -2 - 6

Let f(x)=3x^2+x-3 and g(x)=x^2-5x+1. Find f(x)-g(x).
Step-by-step explanation:
f(x) - g(x) = 3x² + x - 3 - ( x² - 5x + 1 )
= 3x² + x - 3 - x² + 5x - 1

Solve for p.
−160=22+8(3p−4)
Answer:
[tex]p=-6.25[/tex] or [tex]p=\displaystyle-\frac{25}{4}[/tex]
Step-by-step explanation:
[tex]-160=22+8(3p-4)[/tex]
Our goal here is to isolate p on one side of the equation. We will do this by performing inverse operations on both sides.
Subtract 22 from both sides:
[tex]-160-22=22+8(3p-4)-22\\-182=8(3p-4)[/tex]
Divide both sides by 8:
[tex]-22.75=3p-4[/tex]
Add 4 to both sides:
[tex]-22.75+4=3p-4+4\\-18.75=3p[/tex]
Divide both sides by 3:
[tex]-6.25=p[/tex]
You can also convert this into a fraction:
[tex]p=\displaystyle-\frac{25}{4}[/tex]

Answer:
Mid point of A(9,2) and B(6,44) is (7.5, -1)
Step-by-step explanation:
I. If mid point = [tex]\frac{x_{a} +x_{b} }{2}[/tex], [tex]\frac{y_{a}+ y_{b} }{2}[/tex]
So (x) = (9 + 6) / 2 = 7.5
(y) = (2 + (-4)) / 2 = -1
So (x,y) = (7.5, -1)

Hint: label the figure.
x-sin

Use the area of rectangle formula which is:
[tex] \displaystyle \large \tt{A = width \times length}[/tex]
Given that:
area of rectangle = 16width = 8length = x-5Substitute in the formula:
[tex] \displaystyle \large{16 = 8 \times (x - 5)} \\ \displaystyle \large{16 = 8(x - 5)}[/tex]
Distribute 8 in the expression:
[tex] \displaystyle \large{16 = (8 \times x) + (8 \times ( - 5))} \\ \displaystyle \large{16 = 8x - 40}[/tex]
Move -40 to another side and change from -40 to 40.
[tex] \displaystyle \large{16 + 40 = 8x} \\ \displaystyle \large{56= 8x} \\ [/tex]
Then move 8 to divide 56, leaving only x.
[tex] \displaystyle \large{ \frac{56}{8} = x} \\ \displaystyle \large{7 = x} \\ [/tex]
Hence, the answer is:

Answer:
Circle B has an area of 200.96 in².
Step-by-step explanation:
π = 3.14
radius of circle A = diameter of circle A/2
= 16 in/ 2 = 8 in.
Area = πr² = (3.14)(8²)
= (3.14)(64)
= 200.96 in²

Find the greatest number of students for whom 30 apples, 45pears and 60 oranges can be equally distributed. Find the shares of each item.
Answer: The greatest number of students for whom 30 apples, 45 pears and 60 oranges can be distributed equally is 15.
Step-by-step explanation:
taking HCF
so
HCF of 30,45,60
30 = 2*5*3
45 = 3*3*5
60=3*2*2*5
HCF = 3*5 = 15
so
1 student will get = 30/15 = 2 apples
1 student will get = 45/15 = 3 pears
1 student will get = 60/15 = 4 oranges

What is the equation of the line that passes through the point (6,3) and has a slope
of -1/3?
Answer:
y = - [tex]\frac{1}{3}[/tex] x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{1}{3}[/tex] , then
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute (6, 3 ) into the partial equation
3 = - 2 + c ⇒ c = 3 + 2 = 5
y = - [tex]\frac{1}{3}[/tex] x + 5 ← equation of line
