Answer:
140cm cubed
Step-by-step explanation:
5 x 7 x 4 = 140
Answer:
The first one
Step-by-step explanation:
When you do a reflection across the y-axis, it is like a mirror. And if you have a generic point (x, y) the new point will be (-x, y).
In the table you have 4 points:
(x,y)
(-3,9)
(0,0)
(2,4)
(5,25)
The new points will be:
(3,9)
(0,0)
(-2,4)
(-5,25)
set A = {2, 4, 6, 8, 10} (only even cards)
set B = {8, 9, 10} (8 or higher)
( A ∩ B ) means the numbers which are common in both sets .
They both have 8 & 10 in common.
So the answer is: P(A ∩ B) = {8,10}
A.) Mark is correct as every increase in x of 2 equals a y increase of 4
Answer:
y = 17.5
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 35 when x = 140, then
35 = 140k ( divide both sides by 140 )
0.25 = k
y = 0.25x ← equation of proportion
When x = 70, then
y = 0.25 × 70 = 17.5
