Mathematics

topjm [15]3 years ago
5 0

Step-by-step explanation:

We can set up an average equation in the form, where x is the last score in the fourth quarter:

\frac{85 + 88 + 92 + x}{4} = 90

85 + 88+92 + x =360\\\\x = 95

She needs at least a 95 on the last quarter to average 90 in all four quarters.

Tan x=opposite/adjacent
cot x=adjacent/opposite

so you need to inverse the fraction
tan x=.78 as a fraction is 78/100
-> inversed= 100/78=1.28=cot x

so it is the second option

A scientific calculator has 42 buttons. There are twice as many grey buttons as orange buttons. There are two more white buttons
Arlecino [84]

Answer:

x + 2x + 2x + 2 + 4x + 4 = 42

Step-by-step explanation:

Let us assume the number of orange buttons be x

So, the grey buttons be 2x

The white buttons would be 2x + 2

And the black buttons be 2(2x + 2) i.e. 4x + 4

Also the total is 42 buttons

So, the equation is

x + 2x + 2x + 2 + 4x + 4 = 42
