Coordinates after 270 clockwise rotation is (-6,-2), (-3,-5) and (-8, -5).

<h3>What is graph?</h3>

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given coordinates are: (-2,6) , (-5, 3) and (-5, 8)

For 270° clockwise about the origin, we have the following rule:

(x, y)= (-y, x)

So,

coordinates (-2,6) change into (-6,-2)

coordinates (-5, 3) change into (-3,-5)

coordinates (-5, 8) change into (-8, -5).

The volume of construction work was increased by 60% but the productivity of labor increased by only 25%. By what percent must t

Sergeu [11.5K]

Answer: 28 %

Step-by-step explanation:

Let, Initially,

V be the volume of construction work

r be the productivity of labor

n be the number of days

x be the number workers.

Thus, V = r × n × x ------------(1)

Now, According to the question,

The volume of construction work was increased by 60% but the productivity of labor increased by only 25%.

Therefore,

Final volume of the work = 160% of V = 1.6 V

Final productivity = 125% of r = 1.25 r

Also, the time is same in both conditions,

Final time taken = n

Let y be the number of people after changes.

Thus, 1.6 V = 1.25 r × n × y -----(2)

Dividing equation (1) by equation (2)

We get, y = 1.60 x/1.25

Thus, the changes in the number of workers

= $\frac{(\frac{1.60x}{1.25}-x) }{x}\times 100$

= 0.28 × 100

= 28 %

Joe has eaten 3/5 of pizza. Jane has eaten 1/7 of pizza. how many times more pizza has Joe eaten than Jane

Lana71 [14]

The answer would be 14/5.

First of all, get the denominators to be the same. The LCM is 5 × 7 = 3/5

So 1 /7 × 5/ 5 = 5 /3/5

And 2/ 5 × 7 /7 = 14 /35

Now we have 5 /35 and 14 /35

Then all you have to do is divide Joe's by Jane's to get the answer.

14 /35 ÷ 5 35 =14 /35 × 35/ 5 = 14 /5

Meaning the answer is 14/5.

Hope I could help! :)
