what is the distance between points M(-3, 1)and N(7, -3)
Answers
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

answer explanation:
surface area - multi step
Answers
Answer:
£208
Step-by-step explanation:
Given:
Height of solid box (h) = 20 cm
Width (w) = 80 cm
Length (l) = 10 cm
Cost of paint = £0.04 per cm²
Required:
Cost of painting the box
Solution:
✔️First, find the surface area of the box
Surface area = 2(l*w + l*h + w*h)
S.A = 2(10*80 + 10*20 + 80*20)
S.A = 2(800 + 200 + 1,600)
S.A = 2(2,600)
S.A = 5,200 cm²
✔️Find the cost of painting 5,200 cm² surface area of the box.
Cost of pianting 1 cm² = £0.04
Cost of painting 5,200 cm² = 5,200 × 0.04
Cost of painting the box = £208

Find the volume of a hexagonal pyramid with a base area of 25 square inches and a height of 9 inches.
4. Find the volume of a cone with a height of 30cm and a base diameter of 24cm.
5. Mary has a cube with side lengths that measure 5 units and James wants to make a cube that is 3 times the length of Mary's cube. How will the volume of James' cube compare to Mary's? Be very specific.
Answers
Problem 3
Answer: 75 cubic inches-----------------------------
Explanation:
It doesn't matter what shape the base is, so the fact it's a hexagon isn't useful info here. What is useful is that the area of the base is 25 square inches.
We multiply this base area by the height, and then divide by 3 to get the volume of the pyramid.
V = (BaseArea*height)/3
V = (25*9)/3
V = 75 cubic inches
==========================================================
Problem 4
Answer: Exact volume = 1440pi cubic cmApproximate volume = 4521.6 cubic cmThe approximate volume is found by using pi = 3.14
-----------------------------
Explanation:
We apply this formula to find the volume of a cone
V = (1/3)*pi*r^2*h
In this case, r = 12 is the radius (half the diameter) and h = 30 is the height.
So,
V = (1/3)*pi*12^2*30
V = (1/3)*pi*4320
V = (1/3)*4320*pi
V = 1440pi ...................... exact volume in terms of pi
V = 1440*3.14
V = 4521.6 ....................... approximate volume if you use pi = 3.14
==========================================================
Problem 5
Answer: 27 times larger volume-----------------------------
Explanation:
Mary's cube has side lengths of 5 inches, so the volume of this cube is 5*5*5 = 5^3 = 125 cubic inches.
James then wants to triple the side lengths of her cube to have a new larger cube that has side lengths of 3*5 = 15 inches. The volume of this new larger cube is going to be 15*15*15 = 15^3 = 3375
To compare the two volumes, we'll divide the larger over the smaller
(larger volume)/(smaller volume) = (3375)/(125) = 27
This number 27 is due to cubing the value 3, ie 3^3 = 3*3*3 = 27
So the larger cube is 27 times larger compared to the smaller cube.
As another example, let's say he wanted to only double the side lengths. This would mean the larger volume is 8 times larger, since 2^3 = 2*2*2 = 8. Whatever the linear scale factor is, cube it and you'll get the volume scale factor.

Solve for x&y, y=3x-4 & y= 2x + 1
Please show step by step how you got the answer
Answers
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).

How many triangles can be constructed with angles measuring 50º, 90º, and 40º?
Answers
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.

Work is when there is energy that is exerted throughout an object using force and action. Which displaces the measure of the force and the application of that specific action.

Computation:
Work done W = Force x distance
Work done W = 50 x 15
Work done W = 750 J
A Pair of tweezers is an example of a Third Class lever. The force is applied in the middle of the tweezers which causes a force at the tips of the tweezers. The fulcrum is where the two halves of the tweezers are joined together. Whereas a pair of scissors and a pair of pliers is an example of a first class lever.
Power is the rate of using energy or the rate of doing work. Basically, any units of energy (or work) and time can be used to generate a unit of power and can be computed as Work/time. Watt is the standard metric unit of power.
We can use a case scenario to illustrate what Power is. If you take a book and lift it a meter high, you will end up doing the same amount of work regardless of whether you lift the book slowly or quickly. However, you can increase your power which is the rate of doing work when you lift the book quickly.
Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 - 1819)
energy which a body possesses by virtue of being in motion is kinetic
Kinetic energy is when an object has the power to move, Potential energy would be when its resting on the shelf.
Earth is surrounded by invisible gases that form a thin protective blanket that we call the atmosphere. It contains the oxygen that we breath as well as other important gases such as nitrogen, carbon dioxide, water vapor, and ozone.
The permanent gases whose percentages do not change from day to day are nitrogen, oxygen and argon. Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.
Weather maps show these areas using a large “H” to areas bring fair weather with clear skies, while Low pressure brings stormy weather and clouds.
Cumulus clouds look like fluffy, white cotton balls in the sky. They are beautiful in sunsets, and their varying sizes and shapes can make them fun to observe! Stratus cloud often look like thin, white sheets covering the whole sky.

Add all of the deductions together and subtract them by 880
By using g00gle I found out that 195.82 + 63.60 + 134.64 + 176.00 = 635.24.
So now you subtract it by her salary down below:
880.00 - 635.24 = 244.76
244.80 or 245 if I'm not wrong
Cindy's net income on each paycheck will be $244.76.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

State income taxes: $63.60
Insurance: $65.18
FICA: $134.64
Retirement plan: $176
Add all of the deductions together;
195.82 + 63.60 + 134.64 + 176.00 = 635.24.
So now we will subtract it by her salary down below:
880.00 - 635.24 = 244.76

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
Answers
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
