Answer:

Question 1) D The temperature dropped 4 degrees each hour for 5 consecutive days.

Question 2) B Alana needs 4 1/2 more cups of sugar.

Step-by-step explanation:

Question 1) Since the 4 is negative, this means that something needs to be decreasing. The temperature is the only example in which this is the case.

Question 2) If one pumpkin pie calls for 1 1/4 cups of sugar, four pumpkin pies calls for 5 cups of sugar: 4*1 1/4. Since Alana already has 1/2 cup of sugar, 5-1/2=4 1/2.

A. Round to the nearest hundredth
aniked [119]

a. Rounding to the nearest hundredth  means that we only have access to numbers with 2 decimal digits. Our number is enclosed between 45.28 and 45.29. Which one is a better approximation? Well, the one who's closer! To tell how "close" two numbers are, just compute the absolute value of their difference:

|45.28502
-45.28|=0.00502,\quad |45.28502
-45.29|0.00498

So, the distance from 45.29 is less than the distance from 45.28, which makes 45-29 the best approximation.

b. Rounding to the nearest integer  means that we can't use decimal digits at all. By the same logic of case (a), we have to choose between 27 and 28: we have

|27.499-27|=0.499,\quad |
27.499-28|=0.501

Which makes 27 the best approximation

c. Rounding to the nearest tenth  means that we can only use one decimal digit. Again, the logic is always the same: the number lies between 0.2 and 0.3, and we use the same test to check which is a better approximation:

|0.224-0.2|=0.024,\quad |0.224-0.3|=0.076

Which makes 0.2 the best approximation.

1. Se tiene que 5 kilogramos (kg) de almendra y 4 kg de nuez cuestan $44.00, mientras que 8 kg de almendra y 6 kg de nuez cuesta
Sholpan [36]

Answer:

x = 6.00 $/kg ----> almond

y = 3.5 $/kg ------> nut

Step-by-step explanation:

To find the price per kg of each product you first write the algebraic equations for the given relations:

x : price per kg of almond

y: price per kg of nut

Then, you have:

5x + 4y = 44.00      (1)

8x + 6y = 69.00     (2)

By using substitution you have from (1):

y = (44.00-5x)/(4) = 11.00 - (5/4)x

you replace this expression for y into (2):

8x+6[11.00-(5/4)x] = 69.00

8x+66.00-(15/2)x = 69.00

8x-(15/2)x = 69.00 - 66.00

(1/2)x = 3.00

x = 6.00 $/kg ----> almond

And for nut:

y = 11.00 - (5/4)x = 11.00 - (5/4)(6.00) = 3.5$/kg

y = 3.5 $/kg ------> nut

What is the solution of 3x+y=2 & 4y=12-12x?
lorasvet [3.4K]

Answer:

Step-by-step explanation:

3x+y=2............(1)

4y=12-12x........(2)

Making y as subject in (1) and substitute in (2)

y = 2 - 3x......(3)

4(2 - 3x) = 12-12x

8 - 12x = 12 - 12x

12x - 12x = 12- 8

0 = 4

So no solution since variable cancelled out
