Answer:
B
Step-by-step explanation:
well plug in x and y
so if it says y=2x-3 put it as 7=(2x2)-3 and see if it gives u 7 and if it does di the next set of x and y numbers
Answer:
We know, if we multiply a number x by its multiplicative inverse, the result is 1. So, 0.3 is the multiplicative inverse of 313.
<u><em>Answer:</em></u>
100,000
<u><em>Explanation:</em></u>
To round a number to the nearest hundred thousands, we need to check the digit in the ten thousands position:
1- If this digit is <u>less than 5</u>, we will round down. This means that the digit in the hundred thousands position will remain the same and all digits after it will be converted to zeroes
2- If this digit is <u>equal to or greater than 5</u>, we will round up. This means that we will add one to the digit in the hundred thousands position and convert all digit after it to zeroes
Now, the given number is:
89,659
The digit in the hundred thousands position is 0
The digit in the ten thousands position is 8 which is greater than 5. Therefore, we will round up following rule 2 written above
This means that 89,659 rounded to the nearest hundred thousands would be 100,000
Hope this helps :)
Answer:
Step-by-step explanation:
Given:
From the given figure.
Cone height = 7 mm
Cylinder height = 5 mm
Base radius of the cylinder = base radius of the cone = 3 mm
The volume of the given figure is
Volume = volume of cylinder + volume of cone-----------(1)
The volume cylinder is.
----------(2)
Where: r = radius of the cylinder, h = height of the cylinder.
Put the value of height and radius of the cylinder in equation 2.
The volume of the cylnder is 
The volume cone is.
--------------(3)
Where: r = base radius of the cone, h = height of the cone.
Put the value of height and base radius of the cone in equation 3.
The volume of the cone is 
.
Put the value of the volume of cone and cylinder in equation 1.
Therefore, the volume of the given figure is 
Answer:
AD= 15
AB=30
Step-by-step explanation:
We are given that the Point D bisect the line segment AB
Hence AD = DB
AD= 4x-1
BD=9x-21
Hence
4x-1=9x-21
adding 21 on both sides and subtracting 4x from both sides
4x-4x-1+21=9x-4x-21+21
-1+21=5x
5x=20
dividing both sides by x we get
x=4
Hence
AD = 4x-1
= 4(4)-1= 16-1=15
AD= 15
AB = 2 x AD
= 2 x 15
= 30
