Answer:
The temperature is of -4º at midnight.
The temperature has to rise by more than 4º after midnight to be above freezing.
Step-by-step explanation:
The day starts out at 2° and warms up 9° more by noon.
So temperature of 2 + 9 = 11º at noon.
It warms another 2° before dropping quickly 17° by midnight.
The temperature after midnight is of:
11º + 2º - 17º = 13º - 17º = -4º.
The temperature is of -4º at midnight.
How many degrees would the temperature need to rise after midnight to be above freezing?
Add x, has to be higher than 0. So
-4º + x > 0º
x > 4º
The temperature has to rise by more than 4º after midnight to be above freezing
(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

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
The 1.25 come from
1 year & 3 months
= 5 by 4
Q 10. Raj purchased the following items from the grocery shop :
5 kg wheat = Rs. 38.50 per kg
3 coconuts = Rs. 30 per piece
1 Dettol bottle = Rs. 52.25 per bottle
The shopkeeper asked him to pay = Rs. 324.75
Raj was very good at calculation.
He found some mistake in the shopkeeper's calculations.
Can' you find the mistake ?
Is the amount demanded by the shopkeeper for the item purchased righ
What is wrong ? Write the answer with reasons ( show the calculation
What do you think , how does Raj react in this situation ?
Answer:
The shopkeeper demanded low amount that it needed to be
Answer:
The demand of the shopkeeper is 10 rupee less and i think raj will take those items without correcting cause normally we people always think only of our best nah we dont usually care about others. (lol)
Step-by-step explanation:
so lets see the calculation :
Since he bought 5 kg wheat at rs. 38.50 per kg then total will be = 5* 38.50 = Rs. 192.5
also he bought 3 coconuts at rs. 30 per piece then total will be = 3* 30 = Rs. 90
Also ,
He bought 1 Dettol at Rs 52.25
Then total will be :
Rs. 52.25 + 90 + 192.5
= Rs. 334.75#
Hope this helped
All the best !!

Determine if it is possible to form a triangle with the given side lengths. 7 yd, 8 yd, 9 yd
Answer:
yes it is possible to make a triangle with those lengths.
It is possible to form a triangle with the given side lengths
What is a triangle?A triangle is a two-dimensional geometrical figure that has three sides, three vertices and three interior angles.
Given, three sides are 7 yards, 8 yards, 9 yards.
Let, three sides are 'a', 'b, 'c' and 'a' is the largest among these three.
Then, a triangle can be formed with these three sides if (b + c)>a.
Here, 9 yards is the largest.
Therefore, (7 + 8) yards = 15 yards > 9 yards
Therefore, with these three sides, a triangle can be formed.

so for the first one, I made s as 2 and t as 3. I got 18 for the first one and 6 on the other one so they're clearly not equal.

It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

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.

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.

Answer:
x = 3, y = 7
Step-by-step explanation:
Since we already have y's value, we can plug y into the bottom equation to get 3(5x - 8) = x + 18. We can distribute 3 into 5x and 8 to get 15x - 24 = x + 18. We can now subtract x from the both sides to get all terms on one side to get 14x - 24 = 18. We can now add 24 to both sides to get 42. We can now divide both sides of the equation by 14 to get x = 3. We can plug x into the top equation to get y = 5(3) - 8. We can multiply 5 and 3 together to get y = 15 - 8. We can simplify and subtract to get y = 7. Our final answer is (3, 7)

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
