Jessica purchased a 600-minute pre-paid phone card and called her sister at college. After talking to her sister "t" minutes, she had less than 600 minutes on her calling card. (a) Write an equation to determine the number of minutes remaining on the card. (b) Now, suppose she talked to her sister for 65 minutes, determine how many minutes she has left on her card.
Answer:
1) 600-t
2) 600-t=65
=>t=535
A rectangular prism has a length of 9 in., a width of 4 in., and a height of 1 1/2in. The prism is filled with cubes that have edge lengths of 1/2 in. How many cubes are needed to fill the rectangular prism?
Hey there! :)
Answer:
432 cubes.
Step-by-step explanation:
Volume of rectangular prism: V = l × w × h
V = 9 × 4 × 1.5
V = 54 in³
Volume of cubes: V = s³
V = 1/2³
V = 1/8 in³
Set up an equation to solve for the # of cubes needed (x):
54 = 1/8x
Divide both sides by 1/8:
54 × 8/1 = x
x = 432 cubes.
Evaluate the following expression when x = 6 and y = 2: Fraction with x squared plus y cubed in the numerator and 2 plus x in the denominator. 2.25 5.5 17.25 27.5
Answer:
Option B.
Step-by-step explanation:
The given expression is
[tex]\dfrac{x^2+y^3}{2+x}[/tex]
We need to find the value of given expression when x=6 and y=2.
Substitute x=6 and y=2 in the given expression.
[tex]\dfrac{x^2+y^3}{2+x}=\dfrac{(6)^2+(2)^3}{2+(6)}[/tex]
[tex]=\dfrac{36+8}{8}[/tex]
[tex]=\dfrac{44}{8}[/tex]
[tex]=5.5[/tex]
The value of given expression is 5.5 when x=6 and y=2.
Therefore, the correct option is B.
Answer:

Therefore, the correct option is B.
Step-by-step explanation:
a number cube numbered 1-6 is rolled 30 times and lands on an even number 18 times. How does this frequency compare to the expected frequency based on the probability of the number cube landing on an even number?
Answer:
The frequency is 3 more than expected
Step-by-step explanation:
There are 3 favourable outcomes: {2, 4, 6}
There are 6 possible outcomes: {1, 2, 3, 4, 5, 6}
probability of the number cube landing on an even number = favourable outcomes / possible outcomes = 3/6 = 1/2
If the cube is rolled 30 times, it is expected that in 1/2*30 = 15 times landed on an even number. The frequency: 18 is 3 more than expected

Find the equation of the exponential function represented by the table below:
HELLPPP
Answer:
y = 4 [tex](\frac{1}{2}) ^{x}[/tex]
Step-by-step explanation:
For an exponential function in the form
y = a [tex]b^{x}[/tex]
Use ordered pairs from the table to find values of a and b
Using (0, 4 ), then
4 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), thus
a = 4, so
y = 4 [tex]b^{x}[/tex]
Using (1, 2 ) , then
2 = 4 [tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
b = [tex]\frac{1}{2}[/tex]
Thus exponential function is
y = 4 [tex](\frac{1}{2}) ^{x}[/tex]
Answer:
y = 4 (\frac{1}{2}) ^{x}
f(x) = x2. What is g(x)?
Answer: C
Step-by-step explanation:
f(x) = x²
g(x) has the same vertex as f(x) but is wider so has a vertical stretch by a factor of (1/3).
g(x) = (1/3)x²
Solve -8x+4 ≤ 36
A. x ≥ -4
B. x ≤ 4
C. x ≥ 4
D. x ≤ -4
Answer:
x≥-4
Step-by-step explanation:
-8x≤36-4
-8x≤32
x≥32/-8 when divide by minus you flip from≤ to ≥
x≥-4
Answer:
x ≥-4
Step-by-step explanation:
-8x+4 ≤ 36
Subtract 4 from each side
-8x+4-4 ≤ 36-4
-8x ≤ 32
Divide by -8 remembering to flip the inequality
-8x/-8 ≥ 32/-8
x ≥-4
this is a sketch of the curve with equation y=f(x) the vertex of the curve is at (2,-3)
Answer:
see explanation
Step-by-step explanation:
(a)
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
f(x) + 5 represents a shift up of 5 units, thus
(2, - 3 ) → (2, - 3 + 5 ) → (2, 2 )
(b)
Given f(x) then - f(x) represents a reflection of f(x) in the x- axis
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(2, - 3 ) → (2, 3 )
The vertex of the given curve is the minimum point on the curve.
The vertex of f(x) + 5 is (2,2)The vertex of -f(x) is (2,3)The vertex is given as:
[tex]\mathbf{(x,y) = (2,-3)}[/tex]
(a) The vertex of f(x) + 5
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,y + 5)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-3 + 5)}[/tex]
[tex]\mathbf{(x,y) \to (2,2)}[/tex]
Hence, the vertex of f(x) + 5 is (2,2)
(b) The vertex of -f(x)
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-(-3))}[/tex]
[tex]\mathbf{(x,y) \to (2,3)}[/tex]
Hence, the vertex of -f(x) is (2,3)

Lindsey lives 32 blocks from the grocery store. It takes her 9 minutes to walk 12 blocks. If she continues to walk at the same rate, how long would it take her to walk 32 blocks?
Answer:
if she countinues to walk at that rate it will take her 24 minutes to walk the 32 blocks
Step-by-step explanation:
i took the 12 blocks every 9 minutes and counted for a total of 36 blocks which would take 27 minutes then since we want to know how long it would take for her to walk 32 blocks I found how long it would take her to walk 4 blocks which is 3 minutes (12/3 = 4 9/3 =3) and i subtracted those 3 minutes from the 36 block walk giving you 24 minutes for 32 blocks

A department store sells logo shirts at an original price of $20.
Answer:
Answer is below.
Step-by-step explanation:
Macy forgot that a discount of 25% means the cost is multiplied by 75%.
Take the original price of the shirt, $20, times 75% for each month and times 50% for the employee discount.
20 x 0.75 x 0.75 x 0.50 = $5.63 is the price of the shirt for the employees using all of the discounts.

The number 4,928 will be rounded to the nearest hundred is 4900.
What is rounding off numbers?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done. The crucial figures are preserved when numbers are rounded off.
Given to round off 4928 to the nearest 100
steps to round off,
Determine the two consecutive multiples of 100 that bracket 4928
4928 is between 4900 and 5000
4950 is the midpoint between 4900 and 5000
from the number line, 4928 is less than the midpoint 4950,
Therefore, 4928 rounded to the nearest 100 is 4900.
Hence the digit is 4900.

Constants are numbers without any variables with it.
x and y are the variables here.
-8 is the coefficient of y and hence it is not a constant.
*the value of a constant will not change
Note that the constant includes the symbol too, hence it is -3.7 and not 3.7.
