Answer:

Step-by-step explanation:
Using k as the constant of proportionality.
The expression that expresses the relationship : p varies jointly with the square of d and the cube of u.
Varies jointly means that p will change as 'd' and 'u' will change together with respect to their powers.
We get the expression as:

Answer:
Step-by-step explanation:
if the lines are parallel they have the same gradient.
rearrange the equation to make y the subject and then use the m value as gradient.
-3x=2-y
-3x-2=-y
y=-(-3x-2)
y=3x+2
therefore m=3
slope is 3
Answer: Five cats ate 1 and a quarter of cat food.
Step-by-step explanation
Given:-
Cat food ate by one cat = 1/4 cup
Cat food ate by five cats =

Answer: 200 square units
Step-by-step explanation:
first you think what 60/3 is and you get 20
then you multiply 20x20 and get 400
then you divide by 2 because to find the area of a triangle you use the formula (lxh)/2
The correct answer is option E. which is the product will be 13.86594.
<h3>What is the product?</h3>
Multiplication is the process of determining the product of two or more numbers in mathematics. Given numbers are 3.278 and 4.23.
The product of the two numbers will be calculated as:-
P = 3.278 x 4.23
P = 13.86594.
Therefore the correct answer is option E. which is the product will be 13.86594.
