Step-by-step explanation:
Nathan is making chocolate chip cookies, the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies. He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips. Find the constant of proportionality
From the above question, we can see that the Number of Chocolate chips is directly proportional to the number of Dozen cookies
Hence:
C = Chocolate chips
D = Dozen cookies
Hence:
C ∝ D
C = kD
Where k = Constant of Proportionality.
We are told that , the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies.
Hence:
2 = 4k
k = 2/4
k = 1/2
Also, He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips.
3 = 6k
k = 3/6
k = 1/2
Therefore, from the calculations above, the constant of proportionality is 1/2

Answer:
Since 1/5 is 0.2
and 1/5 × 9 is 9/5
We can do 0.2 × 9
which you should get 1.8
OR you can do 0.2 + 0.2 + 0.2 +0.2 +0.2 + 0.2 + 0.2 + 0.2 + 0.2 (which is 0.2 added 9 times)
Which also results in 1.8
Answer:
she could mabey multiply 9x0.2=1.8
Step-by-step explanation:
it might be 1.8 because if 1/5=0.2 and she needs to find out what 9/5 is so
you need to multiple 9x0.2 but im not sure if im right

Lionel has at most 63/8 cups of flour to bake cookies and a cake. Lionel uses 7/4 cups of flour to make the cake. If each batch of cookies takes 3/2 cups of flour, how many batches of cookies, x, can Lionel bake? Select the inequality that includes the maximum number of batches of cookies Lionel can bake.
A. x⊇49/8
B. 49/8⊆x
C. 49/12⊆x
D. x⊇49/12
Answer:
x ≤ 49 / 12
Step-by-step explanation:
Total cups of flour = 63 /8
Cake = 7/4 cups
Cookies = 3/2 cups per batch
Flour left after baking cake :
63/8 - 7/4
(63 - 14) / 8
49 / 8
Batch of cookies which can be baked, x
Flour left / cups of flour per batch of cookies
x ≤(49 / 8) ÷ (3 / 2)
x ≤ (49 /8) * 2/3
x ≤ 98 / 24
x ≤ 49 / 12

What is the slope of the line shown below?
Answer:
2/3
Use the rise over run formula and then simplify
Answer:
D
Step-by-step explanation:
Slop formula: m = (y2 - y1)/(x2 - x1)
First coordinate: (-3, -7)
Second coordinate: (9, 1)
m = (1- (-7) ) / (9 - (-3) )
m = (1 + 7) / (9 + 3)
m = (8)/(12)
m = 2/3

What is the equation of the horizontal line passing through (3, 8)?
Answer:
Y= -5
Step-by-step explanation:
If y always equals -5 then the x value will change but the y value will not. This means that the slope of the line is zero and will be parallel to the x axis, which is the horizontal line.

You roll a spinner that is numbered 1-4. What is the probability of landing on a number less than 3 and then landing on a 4? (determine the answer and explain your process for doing so)
Answer:
The probability is 1/4
Step-by-step explanation:
So there's 4 possible outcomes. So if you roll the spinner and you can only get one outcome. So it'll be 1/4.
Answer:
P(<3, then 4) = 1/2 x 1/4 = 1/8
Step-by-step explanation:
probability of a number less than 3 would mean landing on a 1 or 2, which has a prob. of 1/2
probability of landing on the number 4 is 1/4
multiply the probabilities

The breadth of the rectangular firls is 20m less than its length.. Find its dimensions if perimeter is 160 m
Answer: length of the rectangular firls = 50
and the breadth = x-20m= 50-20m =30m
Step-by-step explanation:
The perimeter of a rectangle is given as 2(l+b)
let the length be represented as x
such that the breadth = x-20m
so our expression for the perimeter of the rectangular firls becomes
Perimeter = 2l+ 2b
160= 2x + 2 ( x-20)
160= 2x+ 2x-40
160+40 =4x
200= 4x
x= 200/4
x= 50
So the length of the rectangular firls = 50
and the breadth = x-20m= 50-20m =30m
Answer:
Length =60m
Breadth= 20m
Step-by-step explanation:
Breadth of the rectangular firls = 20m
Perimeter = 160m
Length = X
Perimeter of a rectangle = 2(L +B)
Where L= Length
B = Breadth
160 = 2( 20 + X)
160 = 40 +20X
160- 40 =20X
120= 20X
20X = 120
X = 120/20
X = 60
The dimensions are:
Length =60m
Breadth= 20m

What is the price ofpremium gasoline rounded to the nearestdollar? Rounded to the nearest dime?Rounded to the nearest penny?
Answer:
$4 (nearest dollar) ;
$4.4 (nearest dime) ;
$4.41 (nearest penny
Step-by-step explanation:
The actual price of premium gasoline is $4.409 per gallon.
A penny = $0.01 or 1 cent
A dime = $0.1 or 10 cent
Price of premium gasoline to the nearest dollar :
$4.409 is rounded to the nearest unit = $4
Price of premium gasoline to the nearest penny : = $4.409 is rounded to the nearest hundredth = $4.41
Price of premium gasoline to the nearest dime : = $4.409 is rounded to the nearest tenth = $4.4

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 675 square feet. The width of the basement is 1/3
its length. What is the length of Louis's basement?
I am reading this correctly, the width = 1/3 of the length?
If this is the case, and we know that the area is 675, the equation is as follows.
Width x Length = 675 ft2
X = length
1/3 X x X = 675 ft2
To solve for X we have to multiply both sides by 3.
X square 2 = 2601 square feet.
Take the square of each side.
X = 225 sqare feet.
