Kala purchased a prepaid phone card for $25. Long distance calls cost 8 cents a minute using this card. Kala used her card only once to make a long distance call. If the remaining credit on her card is $21.48, how many minutes did her call last?
Answer:
44 minutes
Step-by-step explanation:
25.00-21.48=3.52
this means she used $3.52
which is 352 cents.
Each minute is 8 cents so 352/8 = 44

1. A piece of wire that is 28 inches long is cut into two pieces, each of which is then bent into the shape of a
square. The larger square has side lengths that are three inches longer than the smaller square.
(a) If x is the side length of the smaller square and y is the side length of the larger square, write a system of
equations that models this scenario.
(b) Solve the system of equations and determine the lengths of the two pieces of wire.
Answer:

JKLM is a rhombus. KM is 20 and JL is 48. Find the perimeter of the
rhombus.
Answer:
104 units
Step-by-step explanation:
Given
Shape: Rhombus
[tex]JL = 48[/tex]
[tex]KM = 20[/tex]
Required
Determine the perimeter
The given parameter are the diagonals of the rhombus.
The perimeter (from diagonals) is calculated as thus:
[tex]P = 2\sqrt{(JL)^2 + (KM)^2}[/tex]
Substitute values for JL and KM
[tex]P = 2\sqrt{48^2 + 20^2}[/tex]
[tex]P = 2\sqrt{2304 +400}[/tex]
[tex]P = 2\sqrt{2704}[/tex]
[tex]P = 2 * 52[/tex]
[tex]P = 104[/tex]
Hence, the perimeter is 104 units

Given that p varies jointly as q and r, and p = 7. when q = 2
and r= 1.5, find the following:
a. an equation relating p, q, and r
b. p when q = 4 and r= 6
c. p when p=1 and r=3
d. r when p= 5 and q = 8
Answer:
P = k*q*r
Step-by-step explanation:
P = kqr
7 = k*2*1.5
7 = 3k
k = 7/3
b. P = kqr
= 7/3*4*6
= (7*4*6)/3
= 168/3
= 56
P = 56
c. P = kqr
1 = 7/3*q*3
1 = (7*q*3)/3
1 = 21q/3
Cross product
1*3 = 21q
3 = 21q
q = 3/21
= 1/7
q = 1/7
d. P = kqr
5 = 7/3*8*r
5 = (7*8*r)/3
5*3 = 56r
15 = 56r
r = 15/56

The diameter of a baseball is approximately 3 inches. What is its volume?
Round your answer to the nearest whole number.
A. 9 in^3
B. 13 in^3
C. 113 in^3
D. 14 in^3
Answer:qe
Step-by-step explanation:
The volume of the baseball is 14 in³.
The volume of a sphere can be calculated using the formula:
V = (4/3)πr³
where V is the volume and r is the radius of the sphere.
We have,
Diameter = 3 inch
radius = diameter / 2 = 3 / 2 = 1.5 inches
Substituting the radius into the volume formula:
V = (4/3) π (1.5)³
V ≈ (4/3) x 3.14 x (1.5)³
V ≈ 14.13 in³
Thus, the volume of the baseball is 14 in³.

Find the next 3 term of geometric sequence
Answer:
32, 64, 128
Step-by-step explanation:
Let us start by looking at the geometric progression. A geometric progression multiplies each number by a constant, which we can name r, to get the next term. Let us find this constant:
16÷8=2
8÷4=2
Both expressions confirm that our r, the constant, is indeed 2.
To find the next few terms, we simply multiply by r:
1. 16r=16×2=32
2. 32r=32×2= 64
3. 64r= 64×2 = 128
I hope this helps! Please let me know if you have any further questions :)

Given: A= (0, 0), (2, 1). (3, 1.5). (4, 2). .}ls A a function and why?
Answer:
Yes, it is a function
Step-by-step explanation:
the definition of a function is "a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output." Our input is represented by x, or the first number in the parentheses, and our output is y, or the second number in the parentheses. Because each x value had exactly one output, or y, it is a function

Liang bought a basket of apples to make pies for her friends. The basket of apples weighed ppp pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies.
Write an equation to describe this situation.
What was the total weight of the basket of apples?
Answer:
Equation: p - 3 = 17
Weight of basket of apples = 20 pounds
Step-by-step explanation:
Given that:
Weight of basket of apples = p
Weight of apples eaten by Liang = 3 pounds
Weight of left apples = 17 pounds
According to given statement.
p - 3 = 17
Adding 3 on both sides
p - 3 + 3 = 17 + 3
p = 20 pounds
Hence,
Equation: p - 3 = 17
Weight of basket of apples = 20 pounds

How do we know if values in a table are proportional?
Answer:
To see if multiple ratios are proportional, you can write them as fractions, reduce them and compare them. If the reduced scores are all the same, you have a proportion.

Answer:
(8, - 5 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 4 → (1)
- x - 3y = 7 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the x- term.
- 3x - 9y = 21 → (3)
Add (1) and (3) term by term to eliminate x, that is
0 - 5y = 25
- 5y = 25 ( divide both sides by - 5 )
y = - 5
Substitute y = - 5 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(- 5) = 4
3x - 20 = 4 ( add 20 to both sides )
3x = 24 ( divide both sides by 3 )
x = 8
solution is (8, - 5 )
