Mathematics
1 answer:
Annette [7]3 years ago
4 0

Answer:

X = 7.5

Step-by-step explanation:

First, divide 5 by 3 to find the scale factor:

5/3 = 1.667

Now, multiply 4.5 by 1.667 to find x:

x = (4.5)(1.667)

x = 7.5

Therefore, x is equal to 7.5.

A Math professor scores all tests with a maximum of 100 points. A student must have an average of 90 on six tests to receive an
nignag [31]

Answer:

No, he cannot

Step-by-step explanation:

Lets say the student takes the maximum socre on his last test, so he gets 100. Now, his average on the six texts will be:

(75+85+90+95+94+100)/6 = 89.83

So, if taking 100 is not enough to get to the average of 90, this means he would need a score greater than 100, which is impossible as 100 is the maximum. So, the student CAN'T get an A

5. What is the volume of the geometric solid produced by the triangle below when it is
IgorLugansk [536]

The diagram of the triangle is missing, so i have attached it.

Answer:

Surface area = 9.425 sq.units

Step-by-step explanation:

When a triangle having an interior angle as 30°, 60° or 90° is rotated, then a cone is formed.

Thus, we need to find the surface area of the cone.

Surface area of a cone is πr ² + πrL

where;

r = radius of the cone

L = slant height of the cone

I have attached the cone formed as the second image.

Looking at the image of the cone, we need to find the radius and slant height.

From the triangle image, we can use trigonometric ratios;

tan 30 = BC/AB

In surd form, BC/AB = 1/√3

Thus, BC is equivalent to 1 and AB equivalent to √3

Using Pythagoras theorem, we can find AC.

(AC)² = (AB)² + (BC)²

AC = √[(AB)² + (BC)²]

AC =√[(√3)² + (1)²]

AC = √[3 + 1]

AC = √4

AC = 2

So, radius, r corresponds to BC = 1

And slant height L corresponds to AC = 2.

Thus,r = 1 and L = 2

So,

Surface area of cone = π(1)² + π(1)(2) = π + 2π = 9.425 sq.units
