Mathematics

aliina [53]3 years ago

Answer:

They would be further from the correct answer. It would make it harder for them to determine which one who has the highest score.

Step-by-step explanation:

Team 1 got 4,3 points and Team 2 got 4,2. Then it is evident that Team 1 won. But we get rid of the decimals, they would both get 4 points instead. Who actually won then?

A cone has a volume of 2560π cm cubed and a heigh of 30 cm.
Korolek [52]

Answer:

r = 16 cm

g = 34 cm

LA = 1708.16 cm^2

Step-by-step explanation:

We have that for the cone, the formula is as follows:

v = pi / 3 * r ^ 2 * h

the first thing they ask is to calculate the radius, therefore we solve for r

r ^ 2 = 3 * v / (pi * h)

replacing the volume and height, it remains:

r ^ 2 = 3 * 2560 * pi / (pi * 30)

r ^ 2 = 3 * 2560/30 = 256

r = 16

Now, to calculate the slant height, that is to say g, we can calculate it knowing the height and the radius:

g ^ 2 = r ^ 2 + h ^ 2

g ^ 2 = 16 ^ 2 + 30 ^ 2

g ^ 2 = 1156

g = 34

The lateral area of the cone is given by the following equation:

LA = pi * r * g

replacing

LA = 3.14 * 16 * 34

LA = 1708.16 cm ^ 2

the lateral area is 1708.16 cm ^ 2

Select the graph of the solution set that would represent the following expression. | x | > 5
ZanzabumX [31]

Answer:

It would be the first graph because |x| >5 is solved in two cases

The first case you keep everything the same, just get rid of the absolute value bars

x>5

The second case, you need to switch the sign and make the 5 negative

x<-5

When graphing you want to put an open circle on -5, and 5 because when it is < or > you have an open circle,

You then point the arrows going which ever way your sign is going, this is why the -5 is going to the left because the < sign is pointing left, and same with the 5, the arrow is going right because the > sign is pointing right

Hope this helps ;)

If x2 = 30, what is the value of x?
nataly862011 [7]

Subtract 30, then factor the equation.

... x² = 30

... x² - 30 = 0

... (x -√30)(x +√30) = 0

By the zero product rule, the solutions are values of x that make a factor be zero.

... x - √30 = 0 . . . . the first factor is zero

... x = √30

... x + √30 = 0 . . . . the second factor is zero

... x = -√30

The solutions are . . .

... x = ±√30 . . . . . matches your 3rd choice
