Answer:
1 : 8
Step-by-step explanation:
For similar figures with ratio of sides = a : b
Then ratio of areas = a² : b² and
ratio of volumes = a³ : b³
Given ratio of areas = 1 : 4
linear ratio =
:
= 1 : 2
ratio of volumes = 1³ : 2³ = 1 : 8
Answer:
<u>24 pieces</u> of fruits are use to make 2 fruit salads.
Step-by-step explanation:
Given:
Ken uses 6 apples and 2 bananas to make a fruit salad. He put twice as many oranges as bananas in the salad.
Now, to find the number of pieces of fruit Ken will use to make 2 fruit salads.
So, pieces of fruits use to make a salad are:
Apples = 6.
Bananas = 2.
Oranges = twice of bananas = 2×2=4.
So, total pieces of fruits to make a salad = 
Now, total pieces of fruits to make 2 fruit salads:



Therefore, 24 pieces of fruits are use to make 2 fruit salads.
Answer:
x = 4
Step-by-step explanation:
3x + 2y = 26
y = x + 3
Plug in the equation for y
3x + 2(x + 3) = 26
Multiply the 2 with what is in the parantheses
3x + 2x + 6 = 26
Combine like terms and solve for x
5x + 6 = 26
5x = 20
x = 4
Step-by-step explanation:
x=−y−2z+3
x=y+32z+1
x=13y+23z+13
Answer:
5secs
Step-by-step explanation:
Given the equation of the height expressed ad;
h(t) = - 16t^2 + initial height
Given that initial height = 400feet
h(t) = - 16t^2 + 400
The waste will hit the ground at when h(t) = 0
substitute
0 = - 16t^2 + 400
16t^2 = 400
t² = 400/16
t² = 25
t = √25
t = 5secs
Hence it will take the easte 5secs to hit the ground
