PLS HELP WILL MARK BRAINLIEST

Mathematics
1 answer:
gavmur [86]3 years ago
4 0

Answer:

1. Rolling a number less than 5

         The numbers on a standard dice are 1, 2, 3, 4, 5, and 6. Therefore it is possible to roll a 6, but it is much more likely to be 1-5, simply because there are more of them.

2. Rolling a 2

          Again, it is more likely that the result will be one of the other 5 numbers. But obviously a 2 is still an option, so it's not impossible.

3. Rolling a number less than 10

          Every option is less than 10 so it is certain.

Which graph below solves the following system of equations correctly? y = three over four times x squared minus 3 y = negative t
Zielflug [23.3K]
Let's rewrite the system of equations:
 y = three over four times x squared minus 3
 y = (3/4) x ^ 2 - 3
 y = negative three over four times x squared plus 3
 y = (-3/4) x ^ 2 + 3
 The system of equations is:
 y = (3/4) x ^ 2 - 3
 y = (-3/4) x ^ 2 + 3
 The solutions are:
 (-2, 0)
 (2, 0)

X + 14= -6 idk what the answer is please help me right away
stiv31 [10]

Answer:

x = -20

Step-by-step explanation:

You move the 14 with the 6, since it is addition, it changes symbols ( from + to - ), so it'd be;

x = -6 - 14, since you are subtracting a negative number, you are technically adding them.

the altitude of a right circular cone is 8cm and the radius of the base is 6cm what is its total surface area​
frosja888 [35]

Answer:

301.44 cm ^ 2

Step-by-step explanation:

We have that the total surface area of a cone would be the sum of the base area and the lateral surface area.

the area of the base, being a circle is pi * r ^ 2

the lateral area would come being the multiplication between the inclined height, the radius and the number pi, that is to say pi * r * l

the inclined height is calculated using the Pythagorean theorem, the legs being the radius and the altitude, thus:

l ^ 2 = 6 ^ 2 + 8 ^ 2

l ^ 2 = 100

l = 10

Therefore, we can replace:

A = 3.14 * 6 ^ 2 + 3.14 * 10 * 6

A = 301.44

It means that the total surface area is 301.44 cm ^ 2
