Shya works part-time at a gift-wrapping. the store sells wrapping paper rolls and package of wrapping rolls. there are a total of 125 rolls and package. each roll costs $3.50 and each package costs $2.25. the total of all of the rolls and package is $347.50 . how many rolls of wrapping paper are there? show good work and explanation.
Answer:
y=72
x=53
there are 72 packages
Step-by-step explanation:
3.5x+2.25y=347.5
x+y=125
Thereby y=125-x
so
3.5x+2.25(125-x)=347.5
3.5x-2.25x+281.25=347.5
1.25x=66.25
x=53
53+y=125
y=72
Answer:
60 rolls
Step-by-step explanation:
first thing you want to do is add 3.50 +2.25 = 5.75
Then you divide 347.50 by 5.75
which is 60.34...
if you round that off it will be 60 rolls

Answer:
An equation = 5 > x = -4
Step-by-step explanation:
The first five terms in a pattern are shown below.
-0.5, -0.25, 0, 0.25, 0.5, …
If the pattern continues, which expression can be used to find the nth term?
0.75n − 1.25
−0.25n − 0.25
0.25n − 0.75
−0.5n + 0.25
Answer:
I think this answer is A.
Step-by-step explanation:
I think this because when you subtract 0.5-0.25 you get 0.25. So you would add it to whatever comes next until you get to the 9th term. Then you would be somewhere around the ones place. :)
In the given pattern, the expression that can be used to find the nth term of the sequence is T(n)=0.25n-0.75. The correct option is C.
What is an Arithmetic Sequence?An arithmetic sequence is a sequence in which the difference between any two consecutive terms of the sequence is equal.
Tₙ = a₁ + (n-1)r
where,
Tₙ is the nth term of the sequence,
a₁ is the first term of the sequence,
r is a common difference between every two terms.
Since the given sequence is in an arithmetic progression, therefore, the common difference between any two consecutive terms in the sequence are,
Difference, d = -0.25 - (-0.5)
= -0.25 + 0.5
= 0.25
Also, the first term of the sequence is -0.5. Therefore, using the formula of nth for an arithmetic sequence, we can write,
nth term = a₁ + (n - 1)d
= -0.5 + (n - 1)0.25
= -0.5 + 0.25n - 0.25
= 0.25n - 0.5 - 0.25
= 0.25n - 0.75
Hence, in the given pattern, the expression that can be used to find the nth term of the sequence is T(n)=0.25n-0.75.

Calculate the estimated density of each ball. Use the formula
D = m/V
where D is the density, m is the mass, and V is the volume. Record your calculations in Table A of your Student Guide.
Given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. Record your prediction in Table A.
What is the estimated density of the table tennis ball? Record your answer to the nearest hundredth.
g/cm3
What is the estimated density of the golf ball? Record your answer to the nearest hundreth.
g/cm3
Answer:
Step-by-step explanation:
What is the estimated density of the table tennis ball? Record your answer to the nearest hundredth.
⇒ 0.07 g/cm3
What is the estimated density of the golf ball? Record your answer to the nearest hundreth.
⇒ 1.37 g/cm3
The estimated density of a tennis ball is 0.25 g/cm³.
The estimated density of a golf ball is 0.33 g/cm³.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
To calculate the estimated density of each ball, we need to use the formula D = m/V, where D is the density, m is the mass, and V is the volume.
We can then record the calculations in Table A, along with our predictions about whether each ball will float in water, based on the density of water being 1.0 g/cm³.
For the table tennis ball, we have:
D = m/V = 2 g / 8 cm³ = 0.25 g/cm³.
Based on this density being less than that of water (1.0 g/cm³), we predict that the table tennis ball will float in water.
For the golf ball, we have:
D = m/V = 1 g / 3 cm³ = 0.33 g/cm³
Based on this density being less than that of water (1.0 g/cm³), we also predict that the golf ball will float in water.
We can record our calculations and predictions in Table A as follows:
Ball m (g) V (cm³) Density (g/cm³) Floats in water?
Table tennis 2 8 0.25 Yes
The golf ball 1 3 0.33 Yes

Lin's family has completed 60% of a trip. They have traveled 30 miles. How long is the whole trip?
The number of miles the whole trip is 50 miles.
Given that, Lin's family has completed 60% of a trip.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of miles be x.
so, 60% of x=30
⇒ 60/100 ×x=30
⇒ 0.6x=30
⇒ x=30/0.6
⇒ x=50 miles
Therefore, the number of miles the whole trip is 50 miles.
