Answer:
Part 1 :
Part 2 :
w=6
l = 10
Step-by-step explanation:
Part 1:
Let the width of the rectangle = w
Length of the rectangle = w + 4
Area of the rectangle is given as
60 Sq Yrds
Hence this expression represents the area of the rectangle. Solving which for w will give us the width of the rectangle.
Part 2:
(w+10)(w-6)= 0
either (w+10) = 0
or
(w-6)=0
or both are zero
(w+10) = 0 ⇒ w = -10
not possible as the dimension can not be 0
(w-6)=0 ⇒ w=6
Hence the width is 6 yards
And thus the length will be 6+4 = 10 yards
Step-by-step explanation:
Answer: 16 and 5/4 tbsp of sugar.
7 ÷ 2 = 3.5
Don't worry about the decimal for now, just find how many tbsp of sugar she needs for 6 tbsp of milk.
6 ÷ 2 = 3
3 x 5 = 15
Now, we will focus in the 0.5 tbsp of milk.
Find how much 1/2 a tbsp of milk can get for sugar.
4 1/2 tbsp of milk is 5 tbsp of sugar.
5 ÷ 4 = 1.25
So 16 and 5/4 tbsp of sugar is required.
(Answer for Part A)
7.5?????????? hope you get this right
For this case we must indicate the value of the following expression, expressed in scientific notation:
We have that for multiplication properties of powers of the same base, the same base is placed and the exponents are added:
Then, rewriting the expression we have:
