So i’m not sure if there is a different way to do this but here’s how i did it:
start with 2:5
then just keep going up till you can add both numbers and get 28
so next i multiplied both sides by 2 to keep the ratio and got 4:10
then i went back and tried again and tried multiplying 3
which is 6:15.
that only is 21 students so it’s not right
next i tried 4
2 x 4 = 8
and
5 x 4 = 20
8:20 is still a 2:5 ratio and
8 + 20 = 28
so 8 students were in the teachers play
let me know if i can clarify anything
Answer:
Area/length=width
96/8=12
the width would be 12
You reverse the equation so it would be width x length =area but you are missing the width so you reverse the equation and divide instead to find missing sides
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The red function is a transformation. Transformation have the following rules:
- f(x-a) is a units shifted to the right
- f(x+a) is a units shifted to the left
- f(x)+a is a units shifted up
- f(x) -a is a units shifted down
It shifts the red graph 1 unit to the right. This is f(x-1).
Answer:
D={3,9}
The numbers are 3 and 9
Step-by-step explanation:
The set A
={,,,,,,,,,}
Let B be the sub set of A containing odd numbers
B={1,3,5,7,9}
Let C be the sub set of A containing multiply of 3
C= {3,6,9}
Now let D be the be the sub set of A containing both odd numbers and multiples of 3
D={3,9}
The volume of the planter that measures 60 l, 60 w. 60 h (D) 216000 cm³
<u>Explanation:</u>
Length, l = 60 cm
Width, w = 60 cm
Height, h = 60 cm
Volume, v = ?
We know,
Volume = length ×width × height
Substitute the values in the formula.
Therefore, the volume of the planter is 216,000 cm³
