Girl = 2 parts
Boy = 1 part
So total = 2 + 1 = 3 parts and 60 children = 3 parts so 1 part will be 60 ÷ 3 = 20 students
Multiply 20 to 2 and you will get <em>40 students.</em>

2x + x = 60 that is your equation. Simplify it and you get 3x = 60. 60/3 equals 20 so you have 20 boys but multiply it by 2 since you have twice as many girls and you get 40 girls total.

Which excel cell entry will calculate the square root of 165? =sqrt[165] sqrt(165) sqr(165) =sqrt(165)?
svetoff [14.1K]
Excel expects a + or = sign before math calculations.
Also, for arguments of functions (such as sqrt), parentheses "()" are used.  Brackets "[]" are not acceptable.
That leaves only one remaining option.

Hello!

First you have to find what the temperature was at the 3 stages

It started at 87

Then went down 10

87 - 10 = 77

Then up 17

77 + 17 = 94

Then you take the difference from the current temperature from the lowest temperature

94 - 77 = 17

The answer is D

Hope this helps!

Identify the zeros of the polynomial function N(x)=1/2 (x-1)(x+3).
zhannawk [14.2K]

Answer:

a:x=-3

c:x=1

Step-by-step explanation:

The zeros of a function are the values of x for which the value of the function f(x) becomes zero.

In this problem, we have the following function:

f(x)=\frac{1}{2}(x-1)(x+3)

Here we want to find the zeros of the function, i.e. the values of x for which

f(x)=0

In order to make f(x) equal to zero, either one of the factors (x-1) or (x+3) must be equal to zero.

Therefore, the two zeros can be found by requiring that:

1)

x-1=0\\\rightarrow x=+1

2)

x+3=0\\\rightarrow x=-3

So the correct options are

a:x=-3

c:x=1
