A box of chocolates contains only white and dark chocolates in a 2 : 7 ratio. Fill in the gap in the following sentence: 2 in every chocolates are white.
Answer:The given information is 24 total chocolates. You have a 2 to 1 ratio, so 24 ÷ # of milk chocolate = 2 ÷ 1.
24⁄x = 2⁄1 solve for x, milk chocolate = 12.
milk chocolate (12) + plain chocolate (24)= 36 Total

Find a, R, and T.
a = 4, R = 147, T = 33
Step-by-step explanation:
find a
a/(a + 7) = (16/3)/(44/3)
a/(a + 7) = 16/44
44a = 16a + 112
44a - 16a = 112
28a = 112
a = 112/28
a = 4
find R
2x + 5 = 3x - 9
5 + 9 = 3x - 2x
14 = x
m ∠R = 180° - (2x + 5)
= 180 - (2(14) + 5)
= 180 - (28 + 5)
= 180 - 33
= 147°
find T
m ∠T = 3x - 9
= 3(14) - 9
= 42 - 9
= 33°
one-third of a number is at least 5 units from 31
Answer:
6
Step-by-step explanation:

proved
One-third of the number is at least 5 units from 31. The number is 78.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that one-third of a number is at least 5 units from 31. The unknown number is x.
( 1 / 3 )x + 5 = 31
x + 15 = 31 x 3
x + 15 = 93
x = 93 - 15
x = 78
Therefore, one-third of the number is at least 5 units from 31. The number is 78.

Solve the inequality.
Answer:
w ≤ 2/5
Step-by-step explanation:
−2w+7≥3w+5
Step 1: Subtract 3w from both sides.
−2w+7−3w≥3w+5−3w
−5w+7≥5
Step 2: Subtract 7 from both sides.
−5w+7−7≥5−7
−5w≥−2
Step 3: Divide both sides by -5.
−5w/−5≥−2/−5
w≤2/5
Answer:
w ≤ 2/5
Aimee went to a stationary shop. She purchased 2 packs of red pens, 4 packs of black pens, and 3 packs of blue pens.
The cost of each pack of pens was $2.50. Which expression shows the total amount Aimee spent on the pens?
A ($2.50 x 2 x 4x3)
B $2.50 x (2+4+3)
C($2.50 x 2) + 3+4
D (52.50 +2 +4+3)
Answer:
A.
Step-by-step explanation:
The answer is B.
Each pack costs 2.50, so this means we can add all of our packs brought together, before multiplying. (2+4+3)=7. So our final equation should be 7 x 2.50 ,therefore B is our correct answer.

Answer:
Based on the graphs shown, what would you conclude about the conditions under which enzymes function in cells?
A
Enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature.
B
С
Enzymes do not have a specific pH or temperature at which they are most effective but function optimally over a range of pH and temperature.
Enzymes work equally well at the low and high ends of their temperature range but reaction rate drops quickly at the high end of their pH range
Enzymes only function at a specific pH and temperature and cannot function over a range of pH or temperature.

Step-by-step explanation:
The Mad Hatter is ordering cups from Teacups
Limited, for his tea party. The Tescups, Limited catalog
prices cups according to the number of cups ardered. For
orders of 20 or fewer cups, the price is $1.40 per cup plus
$12 shipping and handling on the order. For orders of
more than 20 cups, the price is $1.10 per cup plus $15
shipping and handling
a) Create a piece wise function to describe the
price of cups
b) How much will it cost the Mad Hatter if he orders
20 cups?
a) The piecewise function is:
[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]
[tex]C(n) = 15 + 1.1n, n > 20[/tex]
b) Applying the piecewise function, it is found that it will cost $40.
A piecewise function is a function that has different definitions based on the input.
Item a:
20 or fewer cups, fixed cost of $12 for shipping plus $1.40 per cup. Thus, the first definition of the function for the cost of n cups is:[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]
For more than 20 cups, price of $1.1 per cup plus a shipping and handling fee of $15. Then:[tex]C(n) = 15 + 1.1n, n > 20[/tex]
Then, the piece-wise function is:
[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]
[tex]C(n) = 15 + 1.1n, n > 20[/tex]
Item b:
The cost of 20 cups is C(20).It is the first definition, which is valid for [tex]n \leq 20[/tex].Then:
[tex]C(20) = 12 + 1.4(20) = 12 + 28 = 40[/tex]
It will cost $40.
