Which expression correctly represents the product 12(8 5) after applying the distributive property?

Answers

Answer 1
Answer:

Answer:

Distributive Propety

Step-by-step explanation:

We are given the following information in the question:

Distributive Property:

  • It helps us to perform complicated maths problem easily.
  • The distributive property allows us to multiply a sum by multiplying each addend separately and then adding the products separately.
  • a* (b+c) = (a* b) + (a* c)
  • Example:

5* 8 =5* (2+6) = (5* 2) + (5* 6) = 10 + 30 = 40

The given problem can be solved as:

12* (8+5)\n=(12* 8) + (12* 5) \n= 96 + 60\n=156
Answer 2
Answer: u don't use the distributive property here order of operations says do operations in parentheses FIRST 12(8 +5) = 12(13) = 156 12(8 +5) = 12(8) +12(5) = 96 +60 = 156

Hayden is a manager at a landscaping company. He has two workers to landscape an entire park, Cody and Kaitlyn. Cody can complete the project in 8 hours. Kaitlyn can complete the project in 6 hours. Hayden wants to know how long it will take them to complete the project together. Write an equation and solve for the time it takes Cody and Kaitlyn to complete the project together. Explain each step.

Answers

Cody can do the job in  8  hours.
He does  1/8  of the job each hour.

Caitlyn can do the job in  6  hours.
She does  1/6  of the job each hour.

Working together, they do (1/8 + 1/6) of the job each hour.
Can you add those fractions ?
Change both to a denominator of  24.
1/8 = 3/24
1/6 = 4/24
                   (1/8 + 1/6) = (3/24 + 4/24) = 7/24

Working together, they do  7/24  of the job each hour.

Invert  (7/24  job/hour)  and you have  (24/7  hour/job) .

24/7  =  (3 and 3/7) hour/job.

Together, it takes them  3-3/7 hours.
(That's 3hours 25minutes 42.9 seconds.)

The question says "write an equation".

The equation could be     H (number of hours) = 1 / (1/8 + 1/6)

The orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula mc023-1.jpg. If Saturn’s orbital period is 29.5 years, what is its distance from the sun?

Answers

Given that the orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula P = a^(3/2). If Saturn’s orbital period is 29.5 years, then 29.5 = a^(3/2) a = (29.5)^(2/3) = 9.547 Therefore, Saturn's distance from the sun is 9.547 astronomical units.

Given f(x) = x – 10, what is f(–7)?A.
–17

B.
–10

C.
–7

D.
–3

Answers

Answer: A. -17

Step-by-step explanation:

Here,  the given function is,

f(x) = - x - 10

By substituting x = -7

We get,

f(-7) = -7 - 10

\implies f(-7) = - (7+10)

\implies f(-7) = -17

Thus, the value of f(-7)  is  17.

⇒ Option A is correct.
easy
put -7 for every x
f(x)=x-10
f(-7)=-7-10
f(-7)=-17

Write the equation of line perpendicular to y = 4 that passes through (5, 2).

Answers

Answer:

x= -5

Step-by-step explanation:

just graphed it . y = 4 is a flat horizontal line.

x=5 is a vertical line that passes through (5,2)

Final answer:

The equation of the perpendicular line is x = 5.

Explanation:

To find the equation of a line perpendicular to y = 4 that passes through the point (5, 2), we need to determine the slope of the original line. The equation y = 4 represents a horizontal line with a slope of 0. Perpendicular lines have slopes that are negative reciprocals of each other. The negative reciprocal of 0 is undefined, so the equation of the perpendicular line will be x = 5.
