Answer:
10 days to complete
Step-by-step explanation:
for mixed rate problems, the sum of each individual reciprocal rates equals the sum of the combined rate
i.e
we are given,
A's rate = 15 days to complete
Combined rate = 6 days to complete
B's rate = need to find
substituting' the given info into the equation above,
1/15 + 1/ (B's Rate) = 1/6
1 / (B's Rate) = 1/6 - 1/15 (convert right side to same denominator)
1 / (B's Rate) = 5/30 - 2/30
1 / (B's Rate) = 3/30
1 / (B's Rate) = 1/10 (taking reciprocal of both sides)
B's rate = 10 days to complete
Answer:
10 days to complete
Step-by-step explanation:
Answer:
5 is a constant. (it has no variables)
x + 2 is not a constant. It does, however, have two terms, x and 2.
(terms are separated by addition/subtraction)
This rules out a and b.
As for c... 5(x+2) implies multiplication, which would be a product, not a sum.
d. The product of a constant factor 5 and a 2-term factor x+2
15
Step-by-step explanation:
The value that would be put for r is; 0.042
We are given the monthly payment formula for present value as;
M = (Pr(1 + r)ⁿ)/(1 - r) - 1
Where;
P is Present Value
r is interest rate
n is number of times compounded
Now, we are told the interest rate is given as 4.2% and so we can write that; r = 4.2/100 = 0.042

Answer:
rate of change = 2 ft /min
initial value = 175 feet elevation
Step-by-step explanation:
we are given that his altitude rose 10 feet for every 5 min,
hence the rate of change
= 10 feet ÷ 5 min
= 2 feet/min
we are also given that he hiked for an hour and ended up at 295 feet
1 hour = 60 min.
for a rate of 2 feet / min, if he walked 60 min, he would have walked:
2 feet/min x 60 min = 120 feet.
final value = initial value + change
initial value = final value - change
= 295 - 120
= 175 feet elevation

Answer:
1/9⁷
Step-by-step explanation:
(⁵
⁻⁹)/(
³) For the given equation
STEP:1 The negative power of 9 becomes positive as we make reciprocal of 9.
(⁵*(1/
⁹))/(
³)
STEP:2 The Power 5 got divided with power 9 in the numerator part gives
(1/9⁴)/9³
STEP:3 Now Solving the numerator and denominator part of the equation gives
as the denominator 9³ got reciprocal giving 1/9⁴⁺³. The powers will add as the base is same i.e 9.
STEP:4 This will give the answer 1/9⁷.
Answer:
1/9⁷

Answer:
The correct answer is A. The cost of pizza in dollars per square inch
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Cost of the pizza = $ 0.10 * π * r², where r = radius of the pizza in inches
2. What does the constant 0.10 in the function represent?
Let's recall the formula of the area of a circle, in this case, the area of the pizza:
Area = π * r², therefore the constant 0.10 that is multiplying the area of the pizza, is the cost of the pizza in dollars per square inch and the total cost is the result of the multiplication of the area by 0.10.
The correct answer is A. The cost of pizza in dollars per square inch
Answer:
A) the cost of pizza in dollars per square inch
