How long will it take 4 machines to complete a task, given that 7 machines can complete the same task in 8 days?

Answer:

y=2x+3

I'm 100% sure in my answer ;)

Step-by-step explanation:

Perimeter= 62 cm

4 × side = 62

side = 62/4

=15.5 cm

Area = (side)²

= (15.5)²

=240.25 cm²

Answer:

Step-by-step explanation:

0.0037037045455 of a mile or 19.55556 feet per second

Answer: 1/270 miles per second

Step-by-step explanation:

Speed is equal to distance over time (s=d/t).

We can plug in 10 miles as distance, and 45 minutes as the time; however, you multiply the time by 60 since a minute has 60 seconds. The equation then becomes:

s=10/45*60

s=10/2700

s=1/270

Her speed is 1/270 mps.

Step-by-step explanation:

given :

log 2 = a and log 3 = b

log 120 =?

solution :

log 120 = log 12×10

= log 2²×3×10

= log 2²+log3 +log 10

= 2.log 2 + log 3 + log 10

= 2a + b + 1

Using the concept of bias, it is found that the correct option is:

(A)  Employees may not want to give critical feedback in person to their manager, so this is likely an  overestimate of Valerie's performance.

Samples have to be well chosen, otherwise, there can be a source of bias. For example, if you want to make a survey about who is better, Pele or Maradona, if you choose only Brazilians, or only Argentinians, the results will be biased, thus a sample with an equal number of Brazilians and Argentinians should be used.

In this problem, Valerie's is their manager, and the employees may be reluctant to give her critical feedback, which means that the proportion of 83% is an overestimate, and the correct option is:

(A)  Employees may not want to give critical feedback in person to their manager, so this is likely an  overestimate of Valerie's performance.

Answer:

2

Step-by-step explanation:

I got this answer by:

1) y = 4 - 2x

2) Move 4 to the other side of the equal sign and make it negative because thats the rule

3) Divide -2 from both sides

4) Answer is 2

y-intercept =4/1

Step-by-step explanation:

Your first point would be at (0,16) because that is the y-intercept. The you would go up 3 and over 1 to plot your next point so it would be at (1,19)

Step-by-step explanation:

It is more precisely called the principal square root of 3, to distinguish it from the negative number with the same property. The square root of 3 is an irrational number.

Answer:

Size, angle measures, position of center of rotation, shape.

Step-by-step explanation:

Step-by-step explanation:

y - 1 = -2(x - 5)

Distribute -2 into the parenthesis:

y - 1 = -2x + 10

Add 1 to both sides:

y - 1 + 1 = -2x + 10 + 1

y = -2x + 11 (This is the slope-intercept form where the slope, m = -2, and the y-intercept, b = 11).  

Using the slope (m = -2) and the coordinates of the y-intercept, (0, 11):

Plot the y-intercept on the graph. Then, use the slope's "rise over run" technique (2 units down, and 1 unit to the right) to plot other points.  Connect the points by drawing a line over them.

The smallest number of bags of each colour that he could buy is 60.

From the information, Ibrahim buys bags of coloured marbles. The blue marbles are sold in bags of 10 green marbles are sold in bags of 6 and white marbles are sold in bags of 12.

Since ibrahim wants to buy an equal number of blue ,green and white marbles, the smallest number of bags will be the lowest common multiple of the numbers. This will be:

6 = 6, 12, 18, 24, 30, 36, 42, 48, 54 and 60

10 = 10, 20, 30, 40, 50, 60

12 = 12, 24, 36, 48 and 60

The smallest common multiple is 60.

Answer:

30th problem.

Step-by-step explanation:

The first question that they both solve would be the LCM, or the least common multiple. Since Olivia is solving every 6th, and Nora is solving every 5th, we need to find the LCM of 5 and 6, which would be 30.

So, the first problem that they both solve would the the 30th problem.

Step-by-step explanation:

So you're going to try to always make the equation be in a y= mx +b point slope form. It just makes creating a graph easier.

First, we're going to put x to the opposite side so it's in the y= mx + b form. Remember that every time you cross the equal sign you do the opposite -[tex]x^{2}[/tex] turns into + [tex]x^{2}[/tex].  

y- [tex]x^{2}[/tex] = -1 becomes y = [tex]x^{2}[/tex] -1.

Now all you have to do is plug in values. I recommend you start off small, so they can fit in your graph.

An example would be x = 2 now you plug in to find y which is [tex]2^{2}[/tex] = 4 -1 = 3. So you graph the point (2, 3).

To find the x- intercept and y- intercept you need to plug in 0. For the y-intercept, plug in 0 for x, since you're trying to find the y.

y = [tex]0^{2}[/tex] - 1. The y-intercept is -1 or the point (0, -1)

For the x-intercept, plug in 0 for y, since you're trying to find the x.

0 = [tex]x^{2}[/tex] -1 . Because you're trying to find x, you need to isolate x. Move -1 to the other side. Again, remember since you're moving across the = sign it changes to be positive. 1 = [tex]x^{2}[/tex]. To get rid of squared, you're going to have to square root it. [tex]\sqrt{x^2}[/tex] = x and [tex]\sqrt{1}[/tex] = 1. So the x- intercept is 1 or the point (1, 0).

To make the graph, know that the y axis is vertical (up and down) and the x axis is horizontal (left right). So, the point (0,0) would be on the bottom left corner.

Answer: 8

Step-by-step explanation

Write as a decimal

7 11/18 is equal to 7.6111

Round the decimal to the nearest whole number:

If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.

If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.

Since 6 is in the tenths place we round up.  7 11/18 can be written as 8 (as whole number)
