The cost to rent a ballroom is $293 up front plus an additional $59 per hour. If a ballroom is rented for 6 hours, what is the cost?
Answer:$647
Step-by-step explanation:
293+(59*6)=
293+454=
647
First start off with 293
Now multiply 59 by 6 because 6 is how many hours they will rent it for.
59 x 6 = 354
After that add the 354 to the 293 we had before.
293 + 354 = 647
So the cost of the ball room would be 647 dollars.

(a) Jasmine ran 55 miles in 4242 minutes. Part A At what rate did Jasmine run? Jasmine ran at a rate of minutes per mile. Part B Katie ran 44 miles. She ran at a rate that was 1.11.1 minutes per mile slower than Jasmine. For how many minutes did Katie run? Explain how you determined your answer.
Answer:
Part A
0.764 minutes/miles
Part B
48.4 minutes
Step-by-step explanation:
a) Jasmine ran 55 miles in 42 minutes. Part A At what rate did Jasmine run?
Jasmine ran at a rate of minutes per mile.
Rate = Minutes/Miles
Minutes = 42 minutes
Miles = 55 miles
Jasmine's rate = 42 minutes/55 miles
= 0.7636363636 minutes/miles
Approximately = 0.764 minutes/miles
Part B
Katie ran 44 miles. She ran at a rate that was 1.1 minutes per mile slower than Jasmine. For how many minutes did Katie run? Explain how you determined your answer.
Rate = Minutes/Miles
Minutes = ?
Miles = 44 miles
Rate = 1.1 minutes per miles
Hence:
1.1 minutes per miles = x/44 miles
x = 1.1 minutes per miles × 44 miles
x = 48.4 minutes

MODELING WITH MATHEMATICS A contractor extends a house on two sides.
A. The area of the house after the the renovation is represented by (x+50)^2
B. Use the polynomial in part (a) to find the area when x=15. What is the area of the extension?
Answer:House=4,225ft^2
Step-by-step explanation:
(15)^2+100(15)+2,500
=225+1,500+2,500
=4,225
(a) The area of the house is [tex]x^2+100x+2500 \; \; ft^2[/tex]
(b) Area of the extension
House =4225 ft^2
Important information :
The area of the house is represented by quadratic expression
[tex](x+50)^2[/tex]
To find out the product to multiply x+50 twice
[tex](x+50)(x+50)[/tex]
Apply FOIL method to multiply the parenthesis
[tex](x+50)(x+50)\\x^2+100x+2500[/tex]
The area of the house is [tex]x^2+100x+2500 \; \; ft^2[/tex]
(b) given x=15. To find area of extension , we replace x with 15 in the answer we got from part (a)
[tex]x^2+100x+2500 \\x=15\\(15)^2+100(15)+2500 \\225+1500+2500\\4,225[/tex]
Area of the extension
House =4225 ft^2

(100 points) A store is offering a 20% discount on all items. Is there a proportional relationship between the original price of an item and its price after the discount? Yes or no.
Answer:
yes, a 20% discount means you are paying 80% of the original price
the proportional relationship between the original price of an item and its price after the discount is the Selling price is equal to 0.8 times the Original price.
What is proportionality?The ratios between the two variables should be considered in order to determine whether a relationship is proportional. The relationship is proportional if the ratio remains constant. The relationship is not proportional if the ratio shifts.
Given this, A store is offering a 20% discount on all items.
thus, the Selling price of the product = (1 - 20%) original price
the Selling price of the product = (1 - 0.2) original price
the Selling price of the product = (0.8) original price
Therefore, The Selling price is equal to 0.8 times the Initial Price, which is the proportional relationship between an item's original price and its price after the discount.

____________________katarina bought a package of 500 stickers are heart. The remaining stickers are stars
Where is the question?
Answer: There are 375 star stickers and 125 heart stickers.
There are 500 stickers with 20 stickers per sheet; 500/20 = 25 sheets of stickers.
25% of each sheet is hearts; 25/100(20) = 5 heart stickers per sheet. 5(25) = 125 total heart stickers.
20 stickers per sheet - 5 heart stickers per sheet = 15 star stickers per sheet. 15(25) = 375 total star stickers.
find compound interest paid when a sum of Rupees 10,000 is invested for 1year & 3 months at 17/2% per annum compounded annualy.
Answer:
Rs 1,073.56
Step-by-step explanation:
The computation of the compound interest is shown below:
Compound interest = Principal (1 + rate of interest)^time period - Principal
= Rs 10,000 × (1 + 17 ÷ 2%)^1.25 - Rs 10,000
= Rs 10,000 × (1 + 0.085)^1.25 - Rs 10,000
= Rs 11073.56 - Rs 10,000
= Rs 1,073.56

Find two consecutive ODD integers such that: The square of the larger is 120 more than the square of the smaller
Answer: See explanation
Step-by-step explanation:
Le the number be x and x+2
The information given can be formed into and equation as:
(x + 2)² = x² + 120
(x + 2)(x + 2) = x² + 120
x² + 2x + 2x + 4 = x² + 120
Collect like terms
x² - x² + 2x + 2x = 120 - 4
4x = 116
x = 116/4
x = 29
The smallest number is 29
The larger number is x + 2 = 29 + 2 = 31
