Show your work on the 2 questions shown in the picture.
1 answer:
Answer:
1. The answer is b ≥ 4
2. m = -11; m> -11
Step-by-step explanation:
1. solve your inequality step-by-step.
-4b + 9 ≤ -7
subtract nine from both sides.
-4b + 9-9 ≤ -7-9
-4b ≤ -16
then divide both sides by 4,
-4b/4 and -16/4,
you get: b ≥ 4
2. to solve:
2m+18>-4
subtract 18 from both sides.
2m + 18 -18 >-4 -18
= 2m>-22,
divide both sides by 2,
2m/2, -22/2
you end up with: m > -11

Well the area of a trapezoid is defined by the following formula:
A =
where b₁ and b₂ are the bases of the trapezoid and h is the height of the trapezoid.
Let's plug in what we know into this formula:
h = 7 the perpendicular distance between the two bases
b₁ = 15 the shorter parallel side
b₂ = 25 the longer parallel side made up of 4 + 15 + 6
so, A =
This is in square units of measure of course, so 140 in²
A =

The volume of a cone is 
where r = radius and h = height. If the cone has a volume of 94.2 cm³ (I assume you didn't mean m³ because that would be ridiculously huge) and a height of 10 cm, we can plug these values into the formula to find the radius. Don't do any rounding.
Now we know that's going to be the radius of our <em>new </em>cone as well since we're keeping the diameter the same. The volume is going to be double 94.2 which is 188.4. Let's solve for the height.
