Answer:
Odd integers are always one more that an even integer:
1st: 2n+1
2nd: 2n+3
Step-by-step explanation:
14n+7 = 10n+15
4n = 8
n = 2
------------
1st: 2n+1 = 5
2nd: 2n+3 = 7
7x=5*(x+2)
7x=5x+10
7x-5x=10
2x=10
x=5
Answer:
If the flask shown in the diagram can be modeled as a combination of a sphere and a cylinder, then its volume is
Use following formulas to determine volumes of sphere and cylinder:
wher R is sphere's radius, r - radius of cylinder's base and h - height of cylinder.
Then
Answer 1: correct choice is C.
If both the sphere and the cylinder are dilated by a scale factor of 2, then all dimensions of the sphere and the cylinder are dilated by a scale factor of 2. So
R'=2R, r'=2r, h'=2h.
Write the new fask volume:
Then
Answer 2: correct choice is D.
Step-by-step explanation:
(a) Find the value of x.
Sum of interior in a triangle = 180
So m<BAC + m<ABC + m<BCA = 180
4x + 10 + 5x + 18 + 3x - 16 = 180
12x + 12 = 180
12x = 168
x = 14
(b) Find the measure of <3.
<3 + <BCA = 180
<BCA = 3x - 16 = 3(14) - 16 = 26°
So
<3 = 180 - <BCA
<3 = 180 - 26
<3 = 154°
Answer:
1
Step-by-step explanation:
3/11 / 3/11 = 1
This is because it is the same value and goes into each other once.
I hope this helps!
