Answer:
B) w=3z+2
Step-by-step explanation:
The slope is 3 given the graph and the y-intercept is 2 since when x=0, y=2. So B must be right.
Answer:
50
Step-by-step explanation:
So you can think of this by grouping it like this:
(1-2) + (3-4) + (5-6) + ... + (97-98) + 99
which is equal to: (-1) + (-1) + (-1)... + (-1) + 99
(each group is equal to -1, and 99 won't have a pair since it's the last one)
then, find how many groups of -1 there are:
the groups start at 1 and end at 98, but there are two in each group, so 98/2 = 49. this means there are 49 groups.
so now, you know that there are 49 -1s, so 49 * (-1) = -49.
finally, you can't forget the extra 99 that didn't have a pair, so -49 + 99 = 50.
The height of the right cone given its volume and its diameter is 47 units.
<h3>What is the height?</h3>
A cone is a three-dimensional object that has a circular base and a vertex.
Height of the cone = Volume of a cone ÷ 1/3(πr²)
Where:
- π = 22/7
- r = radius = diameter / 2 = 30 / 2 = 15 units
- h = height
3525π÷ (1/3 x π x 15²) = 47 units

Area of base = 9pi
curve surface area = 3*pi*15=45pi
total area 54pi
i guess the n here represents pi the answer would just be a since its the most relevant
Answer:
2.64 km
Step-by-step explanation:
24 laps each of 110 meters means a total of :
24 * 110 = 2640 m
which translated to km are: 2.64 km
