The whole number of minutes that Gianna complete each week as a function of x and y:
45x+30y
Since the above number is greater than 450 minutes, we get the inequality:
45x+30y\geq450
Also, "she can complete at most 10 workouts this week" so we deduce the inequality:
\\x+y\leq10
Therefore, the system of inequalities is the following:
45x+30y\geq450
\\x+y\leq10
The above system has many solutions, for example :

What is the least common denominator of the four fractions listed below 20 7/10, 20 3/4, 18 9/10, 20 18/25
Feliz [49]
So what you do is see all the denomenators and factor them (denomenaotrs are the bottom numbres)

10,4,10,25
10=2 times 5
4=2 times 2
10=2 times 5
25=5 times 5
we need to include all of them so we need at leas two 2's, and two 5's
2 times 2 times 5 times 5=100
leact common denomator is 100

aleksklad [387]

Answer:

33.3 Repeating

Step-by-step explanation:

1. You already know that 33 is the whole number so you have 33.

2. 1/3 is converted to .3333333 so you put 33 before the decimal point

3. You get 33.3333333

Hope this helps :)

Heera jogs 2 rounds of the park, whose length is 4.5 km and width is twice its length .Find the total distance covered by her .
Marizza181 [45]

Answer:

54 km

Step-by-step explanation:

The distance she covers would be equal to twice the perimeter of the park which is in the shape of a rectangle

perimeter of a rectangle = 2 x (length x width)

length = 4.5

width = 2 x 4.5 = 9

2 x (4.5 + 9) = 27km

In one walk, she covers a distance of 27km. In two walks, she covers a total distance of 27km x 2 = 54km
