Answer:
g(x) = (x + 31)
f(x)= 3x-9
3×x-9= -9+3×x
=-6x
g(x)=(x+31)
1×x+31=32+1×x
=32x
h(x)=2x-16
2×x-16= 16+2×x
=18x
j(x)= -5(x-2)2
(-5x+10)2
-10x+20= 10×x+20

cups
3 number of cups will be needed to marinade 4 pounds of chicken for grill.
What is Ounce?Ounce is the small unit of weight which is generally equal to the one by 16th of the pounds.
Here we have the data from the question:-
Marcy will use 6 fluid ounces of lemon-garlic marinade for every pound of chicken.
Marcy plans to grill 4 pounds of chicken.
So total marination required will be:-
Total marination =6x4=24 ounces
Now we know that the conversion:-
1 fluid Ounce = 0.125 Cup
24 fluid ounce =0.125 Cup
Hence 3 number of cups will be needed to marinade 4 pounds of chicken for grill.

a.7,329 cm3
b.270 cm3
c.58,633 cm3
d.1,629 cm3
The volume of a standard NBA basketball is 7,329 cm³.
What is the volume of a sphere?The volume of a sphere is given by the formula,
V = 4/3×π×r³
Given the diameter of the ball is 24.1 cm, therefore, the radius of the ball will be 12.05cm (half the diameter of the ball). Thus, the volume of the NBA basketball will be,
V = 4/3 × π × (12.05)³
V = 7,329.084 cm³ ≈ 7,329 cm³
Hence, the volume of a standard NBA basketball is 7,329 cm³.

Mr. Linares manages a construction company which is currently hiring. If today he interviewed 4 carpenters and 2 masons, what is the probability that the first applicant he saw was a carpenter?
Answer:
2/3
Explanation:
total people: 4 + 2 = 6 people
carpenters: 4 carpenters
probability = favourable outcomes/total possible outcomesprobability = 4/6 ≈ 2/3
Answer:
P (carpenter) = 2/3 or 0.67
Step-by-step explanation:
Probabilty of seeing a Carpenter first
Number of carpenters = 4Total number of applicants = 4 + 2 = 6P = No. of carpenters / Total applicants⇒ P (carpenter) = 4/6
⇒ P (carpenter) = 2/3 = 0.67
A bag contains 2 gold marbles, 8 silver marbles, and 20 black marbles. The rules of the game are as follows: You randomly select one marble from the bag. If it is gold, you win $5, if it is silver, you win $2. If it costs $1 to play, what is your expected profit or loss if you play this game?
Answer:
expected loss of 4/30 ≈ 0.13 dollars
Step-by-step explanation:
profit = revenue - expenses
expected profit= expected revenue - expected expenses
how i solve this is by multiplying each revenue and expense by its probability and solving from there
revenue of gold = 5
revenue of silver = 2
revenue of black = 0
this exhausts all of our revenue options
total marbles = 2+8+20 = 30
# of gold marbles = 2
probability of gold = 2/30
# of silver marbles = 8
probability of silver = 8/30
# of black marbles = 20
probability of black = 20/30
expected revenue = sum of possible revenues multiplied by their probability
= 5 * 2/30 + 2 * 8/30 + 0 * 20/30 = 10/30 + 16/30 = 26/30
cost = 1 no matter what
expected profit = expected revenue - expected expenses
= 26/30 - 1
= -4/30
= an expected loss of 4/30
4/30 ≈ 0.13

What is a series?A series is a sum of sequence terms. That is, it is a list of numbers with adding operations between them.
The first term (a₁) = 3 and the common difference (d) = -3. Then the sum of the first 20 terms will be
Sₓ = (x/2) [2a₁ + (x - 1)d]
Then we have

S₂₀ = 10 [6 + (19)(-3)]
S₂₀ = 10 [6 - 57]
S₂₀ = 10 [51]

Answer:
5 lbs cereal squares.
25 Ibs nuts.
Step-by-step explanation:
Let x be the weight of nuts in pounds and y be the weight of cereal squares in pounds.
Total weight of the party mix is 30 pounds.
[tex]x+y=30[/tex] ..... (1)
It is given that,
Cost of nuts = $7 per pound
Cost of cereal = $4 per pound
The cost of mix = $6.50 per pound.

If each student needs 1/3 of a stick of clay to do an art project,and there are 4 sticks of clay, how many students can do the art project?
Answer:
12 students
Step-by-step explanation:
Because the total is 4 sticks, and each student needs 1/3 of a stick, we would have to see how many 1/3 sticks fit into 4 sticks. Because 3 of the 1/3 sticks fit into 1 stick, then 4 sticks would be 4*3=12 of the 1/3 sticks, which means 12 students can do it.
We could also just do: 4/(1/3)= 4*(3/1)=12

height of the box?
A. 15 cm
B. 30 cm
C. 37.5 cm
D. 24 cm
Answer:
Option (B) 30cm.Step-by-Step explanation:
Given:
Volume of Rectangular Prism is 15,000cm³.
Length (l) ➠ 20 cm Width (w) ➠ 25 cmWe know that,
★ Volume of Rectangular Prism = whl ★
Let "h" be the height.
➛ 25 × h × 20 = 15,000
➛ h × 20 × 25 = 15,000
➛ h × 500 = 15,000
➛ h = 15,000 ÷ 500
➛ h = 30
Thus, height of the box is 30 cm.
