Tim has a recipe for chocolate mousse. The recipe is for 8 people. The recipe needs 200g of . Tim wants to make chocolate mousse
Elan Coil [88]
If the recipe needs 200g of chocolate bars, and that recipe feeds 8 people, you need to figure out how many times you'd have to make a recipe to feed 50 people.

50 is not a factor of 8, so we have to break the recipe down. if 200g of chocolate feeds 8 people, then it's safe to assume that 100g feeds 4 people, and 50g feeds 2 people. 

The closest you get to 50 without exceeding it by a factor of 8 is 6 x 8= 48. You'd be missing the chocolate for two people, all you have to do is add 50 grams of a chocolate bar.

You have to multiply each ingredient by 6 therefore everything is exactly the same, just amplified. 200 x 6 =1200, which means you'd need 1200g of chocolate bars + 50g to make a mousse for 50 people. 

Each chocolate bar has 150g, so now what you do is you get the 1250g and divide it by 150g. This will tell you the amount of chocolate bars you need to complete the recipe for 50 people. The answer is 8.33333, which means Tim will have to buy 9 chocolate bars.

Help!! WILL GIVE BRAINLIEST!!! What is the range of possible sizes for side x? Please explain about the rule as well.....
yaroslaw [1]

Answer:

0.2 < x < 11.8

Step-by-step explanation:

The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side, for it to form a triangle. So, we can set up 3 equations, x + 5.8 > 6, 5.8 + 6 > x, and x + 6 > 5.8. This solves out to x > 0.2, x < 11.8, and x > -0.2. We can disregard that last one, because a side can't be negative. Therefore, we know the possible range of values for x.

I hope I could be of help! Please give brainliest!

What is the slope of a line that is perpendicular to the line whose equation is 2x + y = 4
wel

The slope of the line of the equation given is -2 (by solving for y, you get y = -2x+4).


So, in order to be perpendicular, you must take the negative reciprocal.

The slope would be -1/2.

I NEED HELP ASAP!!!!!!
miskamm [114]

Answer:

y = 20/3 * x + 125/3

Question 4 : 3 hours study for score 55 (?)

Step-by-step explanation:

2 points (2, 55) (5,75) were chosen to plot the line of best fit, cuz 5 on the above and 5 below it.

y = mx + b

m = (75 - 55) / (5 - 2) = 20/3

b = y - mx = 55 - (20/3) * 2 = 125/3

Equation: y = 20/3 x + 125/3
