Answer:
y-4 = 1/9(x+8)
Step-by-step explanation:
The point slope form of the equation of a line is
(y-y1) = m(x-x1)
We have a slope of 1/9 and a point (-8,4)
y-4 = 1/9(x--8)
y-4 = 1/9(x+8)
Answer:
The volume of the sphere is 972π mm³
Step-by-step explanation:
To calculate the volume of a sphere we have to use the following formula:
V = volume
r = radius = 9mm
π = pi
V = ⁴⁄₃πr³
we replace with the known values
V = ⁴⁄₃ * π * (9mm)³
V = π * ⁴⁄₃ *729mm³
V = π * 972mm³
V = 972π mm³
The volume of the sphere is 972π mm³
Step-by-step explanation:
Let the length be L.
Let the breath be B.
So, we are given that
length of a rectangle is 7 inches greater than three times its width .
So, according to the Question,
L = 7+ 3B.
So, we know that:-
Area = Length× Breadth.
So, it will be
B × (7 + 3B) = Area.
So,
3B² + 7 is an expression to represent its area.
Answer:
600,000
Step-by-step explanation:
Your answer would be 600,000 because in the hundred thousands place there is a 6.
And that 6 in the hundred thousands place is asking the ten thousands place for help also the digit in the ten thousands place is a 1.
So if you know the rule the 6 can't round up because the 1 is below 4./the rule is 4 and below keep it low 5 or more give it one more.
Ok so the 1 is below 4 and can't bring 6 up so 6 has to stay in it's lane at 600,000
Hope this helps have a great afternoon:)
Answer:
52:91
Step-by-step explanation:
To find a ratio value you need to think of it more as two numerators that together equal one whole. 4+7 is 11 so that would be the denominator. If the sum is 143, then we divide by 11 since one number is 4/11s of 143, and the other is 7/11s of 143. 143/11=13
now we multiply both:
4(13)=52
7(13)=91
Check:
91+52=143
52/91 simplifies to 4/7 or 4:7
i hope this helps!
