Answer:
There are 120 1st graders at Sierra Elementary School this year
Step-by-step explanation:
Let n represent the total number of 1st graders at Sierra Elementary School
Since 45% of all 1st graders at Sierra Elementary School are female students and this year there are 54 female 1st graders, 45% of n is equal to 54
→ n(
) = 54
→ 45n = 5400
→ n = 120
Answer:
a=35, b=14, c=5
Step-by-step explanation:
b+6=20, b+6-6=20-6, b=14
4c-6=14, 4c-6+6=14+6, 4c=20, 4c/4=20/4, c=5
a triangle's angles always add up to 180, 180-55-90(the square means right angle)=35
Answer:
<h3>The answer is option B</h3>
Step-by-step explanation:
To find the constant in the equation pick any values of x and y and substitute it into the equation
First make constant the subject
constant = height × width
From the question
Using
height = 30
width = 2
We have
constant = 30 × 2 = 60
Again
Using
height = 12
width = 5
constant = 12 × 5 = 60
Since the constant is the same for any values used
<h3>constant = 60</h3>
