Let's note the information.
This is what we know:
Every buttons came in packages of 30 per student.
Every bookmark came in packages of 50 per person.
Know, we need to do some multiplying.
30 x 400 & 50 x 400
Now solve.
30 X 400 = 12000.
So we now know that they have an estimated 12000 buttons total.
Now, we find x for bookmarks.
50 x 400 = 20000
That means total that estimated that 20000 bookmarks will be given.
Answer:
y = 5 cos ((2π/3)x - 2) + 2
Step-by-step explanation:
Cosine function takes a general form of y = A cos (Bx + C) + D
Where
A is the amplitude
2π/B is the period
C is the phase shift ( if -C, then phase shift right, if +C phase shift left)
D is the vertical displacement (+D is above and -D is below)
Given the conditions of the function to build and the general form, we can write:
** Note: period needs to be 3, so 2π/B = 3, hence B = 2π/3
Now we can write:
y = 5 cos ((2π/3)x - 2) + 2
first answer choice is right.
Heya!!!
Answer to your question:
1. No. of squares=5
No. of circles=6
Ratio of squares to circles is 5 to 6
So answer is
B. 5 to 6.
2.No. of students=35
No. of teachers =4
Ratio of students to teachers=No. of students/No. of teachers
=35/4
so answer is
C. 35/4
Hope it helps ^_^
Answer:
Width = 17
Length = 92
Step-by-step explanation:
Perimeter of rectangle = 2 (length + width)
let us take width be x
length = 7 + 5x
width = x
so let us put these value
2 (length + width) = 218
2 (7 + 5x + x ) = 218
2 (7 + 6x ) = 218
14 + 12x = 218
12x = 218 -14
12x = 204
x = 204/12
x = 17
Width = x
= 17
Length = 7 + 5x
= 7 + 5(17)
= 7 + 85
= 92
