Answer 1

Answer:

Answer:

4 times

Step-by-step explanation:

Note,

60 seconds = 1 minute
120 seconds = 2 minutes (60*2).

Since the student rode a horse for 120 seconds, to find the number of times the student riding the carousel completed the up-down cycle, we divide it by 30 seconds (which is the duration for the horse to complete one up-down cycle) because the student would be having the same duration as the horse because he was on top the horse.

Hence, we have;

120/30 = 4

Answer:

No because he only won 3/4 not more than 3/4

Step-by-step explanation:

So the part where it says I have won more than 75% of all the games I have played, it is saying he has won more than 75% or 3/4? Which he only won 3/4 not more. 75% is equal to 3/4.

What is the surface area of the square pyramid represented by the net? Enter your answer in the box. cm² An unfolded square base pyramid with sides of the base being seven centimeters and the length from the base to the tip is nine centimeters.

Answers

The surface area of the square pyramid represented by the net is 175 cm².

Given is a net of the square pyramid.

A square pyramid has the base of the pyramid being the square and four triangular lateral faces.

Given that,

An unfolded square base pyramid with sides of the base being seven centimeters and the length from the base to the tip is nine centimeters.

Base length, a = 7 cm

Slant height of the pyramid, l = 9 cm

Surface area = a² + 2al

= 7² + (2 × 7 × 9)

= 49 + 126

= 175 cm²

#SPJ2

Area of the base = 7 x 7 = 49 cm²

Area of the 4 triangles = 4 x [ 1/2 x 7 x 9]
Area of the 4 triangles = 4 x 31.5
Area of the 4 triangles = 126 cm²

Total Surface Area = 49 + 126 = 175 cm²

Answer: Total Surface Area = 175 cm²

Answer:

Step-by-step explanation:

Consider the function f(x) = (3x-7)/2 with a domain of - ∞ < x < ∞what is the range of f^-1(x) [this is the inverse function]

a. - ∞ <_ x <_ ∞
b. - ∞ < x < ∞
c. - ∞ < f^-1(x) < ∞
d. - ∞ <_ f^-1(x) <_ ∞

please help and thank you!!

Answers

Here we have to use the fact that the domain of the function is equal to the range of the inverse function and range of the function is equal to the domain of the inverse function .

In the given question , the domain of the given function is given. So the range of the given option is same as the domain.

Therefore the correct option is c.
