The price per square foot was $98. How much did they pay for the house? Enter your answer in the box.
Answer:$220,290
Step-by-step explanation:
2,255 multiplied by 98 is 220,290
The total cost of Trisha’s parents new house is $220990.
Given that, Trisha’s parents bought a new house that has 2,255 square feet.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The price per square foot was $98.
So, the total cost of house = Number of square feet × The price per square foot
= 2,255 × 98
= $220990
Therefore, the total cost of Trisha’s parents new house is $220990.

Ronnie made 5 pies for New Year's Day. Some of his family members are allergic to gluten, so he bought gluten-free flour for all of the pies. For each piecrust, he used 2 cups of flour. Health Mart sold bags with 4 cups of gluten-free flour for $12. How much did Ronnie spend on the gluten-free flour so that he had enough for the crusts?
Answer:
He spent $24 dollars
Step-by-step explanation:
Each of the piecrusts had 2 cup of flour he has 5 pies so all pies altogether equally 10 cups so he buys 2 bags for $24 dollars
Step-by-step explanation:
Number of gluten-free flour used for 5 pies= 2×5= 10 cups
cost of 4 cups of gluten-free flour = $12
cost of 1 cup = 12/4 = $3
Then,
cost of 10 cups of gluten-free flour = 3×10
= $30

Answer:
Look at explanation
Step-by-step explanation:
All you have to do is plot these points on a graph. Then make a straight line through them.
The y-intercept is the point of the line that passes through y, the vertical line.
The example shows that the y-inercept is (0, 3)
Answer:
you would minus the ys and minus the xs and turn them into a fraction

Write a recursive rule for the sequence –17.-11, -5, 1, ...
show complete working format please
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 6
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
- 11 - (- 17) = - 5 - (- 11) = 1 - (- 5) = 6
A recursive rule allows a term to be found by adding d to the previous term, thus
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 6 with a₁ = - 17

Tyson got a $15 gift card to use on song and movie downloads to his tablet. Each movie, m, costs $5 and each song, s, costs $1. Tyson's mom said he must use fewer than 10 downloads and that his total cost could not exceed the $15 amount on the gift card. Which of the following graphs shows the solution set of the system of inequalities?
Answer:
c
Step-by-step explanation:
bla bla bla
The solution to the inequality m + s = 10 and 5 m + 1s = 15 is shown in the graph attached below, and as it can be seen the coordinated of intersections are (8.75, 1.25), so option C is correct.
What is inequality?Inequalities specify the relationship between two values that are not equal. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal
Given:
Total balance on card = $15,
The cost of each movie = $5,
The cost of each song = $1
The number of downloads = 10,
Write the equation as shown below,
m + s = 10 and 5 m + 1s = 15
Here m is the number of movies and s is the number of songs,
Solve the equation by elimination method,
m = 5/4 = 1.25 and s = 35/4 = 8.75
As you can see, the value of the intersection of inequalities is (8.75, 1.25),
the graph is attached below.
