what is the distance between points M(-3, 1)and N(7, -3)
Answer:
d = 2√29 units
Step-by-step explanation:
M(-3, 1)and N(7, -3)
To find the distance between these two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
Plug in the values.
d = √[(7 - (-3))² + (-3 - 1)²]
Simplify the parentheses.
d = √[(7 + 3)² + (-4)²]
d = √[(10)² + (-4)²]
Simplify the exponents
d = √[(100 + 16)]
Simplify the parentheses by adding.
d = √[116]
Simplify the brackets with the square root.
Since 116 is not a perfect square, we need to find two numbers that multiply to 116. One number must be a perfect square. The other must be a prime number.4 • 29 = 116. Therefore √4 • √29 = √116√4 = 2. Therefore 2√29 = √116d = 2√29 units
Hope this helps!

identify the slope and the intercept for the following inequality -2×-y
[tex]\Huge{\textbf{\textsf{{\color{navy}{ᴀɴ}}{\purple{ᴡs}}{\pink{ᴇʀ}}{\color{pink}{:}}}}}[/tex]
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.
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 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#

Jackie is buying crackers and wants to know how many crackers are in the box. The box is 8 cm long, 2.4 cm wide, and 60 cm high. The dimensions of the crackers are 3cm long, 4 cm wide, and 5 cm high. How many crackers are in the box? Round to the nearest whole number. Geometry
Answer:
19
Step-by-step explanation:
Number of crackers that can be fit into the box = volume of the box / volume of crackers
Volume = length x width x height
volume of the box = 8 cm x 2.4 cm x 60 cm = 1152 cm^3
Volume of the crackers = 3cm x 4 cm x 5cm = 60cm^3
1152/60 = 19.2
Rounding 19.2 to the nearest whole number gives 19

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
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

(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
Solve for x&y, y=3x-4 & y= 2x + 1
Please show step by step how you got the answer
Answer:
(5, 11 )
Step-by-step explanation:
Given the 2 equations
y = 3x - 4 → (1)
y = 2x + 1 → (2)
Substitute y = 3x - 4 into (2)
3x - 4 = 2x + 1 ( subtract 2x from both sides )
x - 4 = 1 ( add 4 to both sides )
x = 5
Substitute x = 5 into either of the 2 equationsfor corresponding value of y
Substituting into (2)
y = 2(5) + 1 = 10 + 1 = 11
solution is (5, 11 )
Answer:
This is a system. put the first equation under the second one and subtract. y - y = 0. 2x - 3x = -x. 1 - (-4) = 5. so the result is 0 = -x +5 or x = 5. plug x into either equation and y = 11. the answer is (5, 11).
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.
6th grade math help me pleaseee
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)

Answer:
1. No
2. Yes
3. No
4. Yes
Step-by-step explanation:
Plug in values for the unknowns into bother expressions to see if the give the same answer.
I don't really know how to do this but the best thing I can say is to replace those variables with a number and then put it in a calculator. Make sure each variable has a different number.
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.
good luck!

How many triangles can be constructed with angles measuring 50º, 90º, and 40º?
Answer:
Infinite
Step-by-step explanation:
We know that in a triangle the sum of all the interior angles must be 180°.
The given angles 50º, 90º and 40º
The sum of the angles 50º+ 90º + 40º= 180°
Thus, a triangle is possible with the given measurement.,
Let there is another triangle with the given angles, then by AAA similarity criteria they are similar.
Similarly, all the triangles with the same measurements of the angles must be similar.
Therefore, there are infinite number of triangles can be possible with angles measuring 50º, 90º, and 40º.

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.

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.
