Answer:
three dimensional figure in which we have height breadth and length
and two dimensional figure in which two unit breadth and lenght
two dimensional has only two measurements, such as length and height and three-dimensional (3D) shape has three measurements, such as length, width, and height
What is Mensuration?The branch of mathematics that studies the measurement of geometric figures and their parameters like length, volume, shape, surface area, lateral surface area, etc
A two-dimensional (2D) shape has only two measurements, such as length and height. A square, triangle, and circle are all examples of a 2D shape.
and three-dimensional (3D) shape has three measurements, such as length, width, and height
The example of two dimensional are triangle, circle.
The example of three dimensional are cuboid, cone , cylinder.
Hence two dimensional has only two measurements, such as length and height and three-dimensional (3D) shape has three measurements, such as length, width, and height

Answer: 1.5 x 10^5
Step-by-step explanation:
The first step is to re-arrange the factors like this :
5 x 3 x 10^2 x 10^2
Since
5 x 3 = 15
and the index law
10^a x 10^b = 10^a + ^b
gives us
10^2 x 10^2 = 10^2 + ^2 = 10^4
then we can rewrite the product like this :
5 x 3 x 10^2 x 10^2 = 15 x 10^4
Finally, we need to convert this into scientific notation :
15 x 10^4 = 1.5 x 10^5
So the final answer is
1.5 x 10^5
How many kilograms of 30% salt solution by mass and 40% salt solution by mass
should be mixed to form 200 kg of 37% salt solution by mass?
Answer:
60 kilograms of the 30% solution
140 kilograms of the 40% solution
Step-by-step explanation:
Let x = the no. of kilos containing 30% salt (solution 1)
and 200 - x = the no. of kilos containging 40% salt solution 2)
.30x = amount of salt in solution 1
.40(200 - x) = amount of salt in solution 2
.37(200) = amount of salt in the final mixture
salt in solution 1 + salt in solution 2 = salt in final mix.
.30x + .40(200 - x) = .37(200)
Let's multiply thru the equation by 100 to remove the decimal fractions
30x + 40(200 - x) = 37(200)
30x + 8000 - 40x = 7400
-10x = -600
x = 60 kilograms of the 30% solution
200 - 60 = 140 kilograms of the 40% solution

Determine if the triples below are right triangles.
Port A: 290, 696, 750
Port B: 514, 684, 855
part C: 450, 1080, 1170
Answer:
Part A is not a rt triangle
Part B is not a rt triangle
Part C is a rt triangle
Step-by-step explanation:
Part A:
290^2 + 696^2 = 750^2
84,100 + 484,416 = 562,500
Add the numbers on the left to see if the 2 sides are equal.
568,516 ≠ 562,500
Part B:
514^2 + 684^2 = 855^2
264,196 + 467,856 = 731,025
Add the numbers on the left to see if the 2 sides are equal.
732,052 ≠ 731,025
Part C:
450^2 + 1080^2 = 1170^2
202,500 + 1,166,400 = 1,368,900
1,368,900 = 1,368,900

Step-by-step explanation:
A basket ball player attempts 15 baskets in a game . He makes 9 of the attemps what is the ratio
Answer:
9:15 or 3:5
Step-by-step explanation:
A ratio can compare a part of a whole to a whole.
In this case, our whole is the total number of shots attempted: 15.
The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.
Put these values in a ration.
part:whole
9:15
Notice that 9 and 15 can be simplified by dividing both numbers by 3.
3:5
This is your simplified ratio.

Which functions have graphs with slopes less than -2?
(Check all that apply.)
Answer:
Function 2
Step-by-step explanation:
✔️Slope of function 1:
Slope (m) = ∆y/∆x
Using two points on the line, (0, 4) and (1, 9),
Slope (m) = (9 - 4) / (1 - 0)
Slope (m) = 5/1
Slope (m) = 5
✔️Slope of function 2:
Slope (m) = ∆y/∆x
Using the coordinates of any two given pairs form the table, (0, 1) and (1, -3):
Slope (m) = (-3 - 1) / (1 - 0)
Slope (m) = -4/1
Slope (m) = -4
✔️Slope of Function 3:
The function is given in the slope-intercept form, y = mx + b
m = slope
The function y = 2x - 5, therefore has a slope (m) of 2
Slope = 2
✔️Slope of Function 4:
Slope (m) = -1
✅Thus, the functions that has slopes less than -2 are:
Function 2: slope = -4
Function 1, 3, and 4 all have slopes that are greater than -2
what is the distance between (4,2) and (4, -1)

sorry do u have a graph paper for this

The question is attached- please help
Answer: Choice A
f(1) = 2
f(n) = 2*f(n-1) for n ≥ 2
===========================================================
Explanation:
n = term number
So for instance, n = 3 represents the index for the 3rd term
We see that when n = 1, f(n) = 2 as shown by the left-most red point.
This means that f(1) = 2 which is a short way of saying "the first term is 2".
So the answer is between A and C.
Let's randomly guess that it might be choice C. We'll use the recursive rule given to generate the next term
f(n) = 4*f(n-1)
f(2) = 4*f(2-1) .... replace every n with 2
f(2) = 4*f(1)
f(2) = 4*2 ..... replace f(1) with 2, since f(1) = 2
f(2) = 8
This tells us that the 2nd term is 8, but the graph says it should be 4. Note the red point at (2,4)
Ultimately this all means that we can eliminate choice C and go with choice A as the final answer.
As a check, let's plug n = 2 into the recursive rule for choice A
f(n) = 2*f(n-1)
f(2) = 2*f(2-1)
f(2) = 2*f(1)
f(2) = 2*2
f(2) = 4
We get the proper second term. I'll let you check the other remaining terms. The notation 2*f(n-1) means "multiply 2 by the previous (n-1) term". In other words, the term values are doubling {2,4,8,16,...}
How would get get the answer 60 if both sides each equal 30? All of the same shape has to equal the same thing. For example all the squares have to equal the same thing. Thanks for your help!
