If someone build a house for 50 years how many months did it take to complete

Answers

Answer 1

Answer:

Answer: 600

Step-by-step explanation: 12 months in one year. 12x50=600 months

Answer 2

Answer:

Answer:

600 months

Step-by-step explanation:

In 1 year there are 12 months, so we take 50 (the years) and multiply that by 12

50x12=600 and we fact check by 600÷12=50. It takes 600 months to build the house over 50 years.

let's solve :

$12x + 20y = 20$

$20y = 20 - 12x$

$y = (20 - 12x)/(20)$

$y = (20)/(20) - (12x)/(20)$

$y = 1 - (3)/(5) x$

so, the slope intercept form of given line will be :

$y = - (3)/(5) x + 1$

Bryce wrote the linear regression equation y=1.123x-6.443 to predict the armspan, y, of a person who is x inches tall. Riley has an armspan of 67.5 inches. Which is the best prediction of Riley’s height? A. 54.36 inches
B. 65.84 inches
C. 66.55 inches
D. 69.36 inches

Answers

Answer:

B. 65.84

Step-by-step explanation:

You are given the armspan and a relation between that and height. Put the given value in the equation and solve for the unknown.

... 67.5 = 1.123x -6.443

... 73.943 = 1.123x

... 73.943/1.123 = x = 65.84

Riley's height is predicted to be 65.84 inches.

This pattern repeats every 5 terms. The pattern is rectangle, pentagon, square, hexagon, pentagon. What is the 19th term of this pattern? Answers Square
Pentagon
Hexagon
Rectangle

Answers

Since the pattern repeats every 5 terms, we can find the remainder when 19 is divided by 5 to determine which term in the pattern the 19th term corresponds to.

19 ÷ 5 = 3 with a remainder of 4

Since there are 5 terms in the pattern, the 19th term is equivalent to the 4th term in the pattern. Therefore, the 19th term is a square.

A masonry contractor is preparing an estimate for building a stone wall and gate. He estimates that the job will take a 40-hour work week. He plans to have two laborers at $10 per hour and six masons at $21 per hour. He'll need $3337 worth of materials and wishes to make a profit of $400. Write a mathematical statement that will give the estimated cost of the job. Then calculate this total.

Answers

Answer:

$9,577

Step-by-step explanation:

Given:

Estimated time for the job = 40 hours

Number of laborers = 2

Per hour laborers cost = $10

Number of masons = 6

Per hour mason cost = $21

Worth of material = $3337

Estimated Profit = $400

Now,

The total amount spent on laborers

= Number of laborers × total working hours × Cost per hour

= 2 × 40 × $10

= $800

The total amount spent on masons

= Number of masons × total working hours × Cost per hour

= 6 × 40 × $21

= $5040

Hence,

the total estimated cost for the job

The total amount spent on laborers $800

The total amount spent on masons $5,040

Worth of material $3,337

Estimated Profit $400

==========================================================

Total estimated cost $9,577
