At 7am last night, the temperature was 10°F. At 7am the next morning, the temperature was -2°F. By how much did the temperature change from 7pm to 7am?

The and would be y=-1/3x-5 because to find slope you would use the equation y2-y1 divided by x2-x1 and find the slope of -4/12 which simplifies to -1/3 and the y-int is -5 so you would just plug that in.

Answer:

slope is 1

Step-by-step explanation:

1 is the coefficient of x variable

so slope is 1

2 * 10 to the 7th plus 6 * 10 to the 6th plus 3*10 to the 5th plus 5000 plus 20 + 6

2 * 10 to the 7th plus 6 * 10 to the 6th plus 3*10 to the 5th plus 5 * 10 to the third plus 20 + 6

Two other ways to write this equation are

1. Standard Form: 26,305,026

2. Written Form: Twenty six million, three hundred five thousand, twenty six.

The smallest value is 56.

First even number + second even number + third even number = 174

First even number: x

Second even number: x + 2

Third even number: x + 4

So, (x) + (x+2) + (x+4) = 174

3x + 6 = 174

3x = 168

x = 56

(56 + 58 + 60 = 174)

Final answer:

The smallest of the three consecutive even numbers whose sum is 174 is determined by setting up an equation and solving for x, which represents the smallest number. The solution reveals that the smallest number is 56.

Explanation:

The question asks for the smallest of three consecutive even numbers whose sum is 174. To find the numbers, we can set up an equation where x represents the smallest even number, x+2 represents the second number, and x+4 represents the third number. The equation will be x + (x+2) + (x+4) = 174. When we solve it, we combine like terms to get 3x + 6 = 174, then subtract 6 from both sides to get 3x = 168, and finally divide by 3 to get x = 56. Therefore, the smallest of the three consecutive even numbers is 56.

answer: y = 1/2x - 3

why?: if you go 1 unit up (which is positive) and go right 2 units (which is positive). you will get 1/2 as your slope. the y-intercept would be -3 because the line passes through the y-axis on -3.

Jess buys a total of 17/16 pounds, which is equivalent to 1 1/8 pounds, of turkey and cheese combined.

Jess buys 5/8 pound of turkey and 7/16 pound of cheese. To find out how much turkey and cheese Jess buys in total, we need to add these two amounts together. Since both quantities are given in pounds, we can add them directly.

First, let's find a common denominator for the fractions 5/8 and 7/16. The common denominator is 16. Now we write 5/8 with the common denominator, which is the same as 10/16. With the fractions having the same denominator, we can add the numerators together:

(10/16) + (7/16) = (10+7)/16

17/16 pounds

So, Jess buys a total of 17/16 pounds of turkey and cheese. This is equivalent to 1 ⅛ pounds when expressed as a mixed number.

Answer:

Total number of jolly ranchers= 140

Total number of candy bars= 60

Now , we have to place jolly and candy into gift bags such that no pieces of candy should left.

1. Find the ratio of jolly ranchers and candy bars

 = 140/60

= 7/3

So, possible combination are (7,3),(14,6),(28,12),(35,15),(70,30).

1.So,in combination (7,3), number of bags=[tex]\frac{Total candy}{(7+3)}[/tex]

                                                                  =[tex]\frac{200}{10}[/tex]

                                                                  =20

2. Number of Bags(14,6)=200÷20=10

3.Number of Bags(28,12)=200÷40=5

4.Number of Bags(35,15)= 200÷50=4

5.Number of Bags(70,30)=200÷100=2

Combination (1) in which there are 7 Jolly ranchers and 3 candy bars has the most amount of bags which is 20.

Step-by-step explanation:

A plane intersects a prism parallel to the base of the prism. The cross section is a polygon with eight sides. The base of the prism has also 8 sides.

The cross-section of a plane parallel to the base is the same shape as the base. The cross section is also an eight sided polygon, so, the base of the prism has 8 sides.

part C:

105$

there is no change at all so you do not save anything.

Equations represent Company A and B's charges. Company B charges less to clean 6 mattresses. No savings are made cleaning 3 mattresses with Company B compared to Company A.

Part A: Let x represent the number of mattresses. The total charges for Company A can be represented by the equation: y = 30x + 15, where y is the total cost. The total charges for Company B can be represented by the equation: y = 28x + 21, where y is the total cost.

Part B: To determine which company would charge less for cleaning 6 mattresses, we substitute x = 6 in both equations:

Company A: y = 30(6) + 15 = 180 + 15 = $195

Company B: y = 28(6) + 21 = 168 + 21 = $189

Therefore, Company B charges less for cleaning 6 mattresses.

Part C: To find out how much money is saved by using Company B instead of Company A to clean 3 mattresses, we substitute x = 3 in both equations:

Company A: y = 30(3) + 15 = 90 + 15 = $105

Company B: y = 28(3) + 21 = 84 + 21 = $105

The charges are the same for 3 mattresses, so there is no money saved by using Company B instead of Company A.

This would be 72 Inches. Or 6 feet.

Answer:

6 is a factor and 36 is neither and 48 is a multiple

Step-by-step explanation:

(-3 ft)/(4 weeks) = -3/4 ft/wk = -0.75 ft/wk

The most approriate choice is ...

... (c) -0.75

The unit rate of change for the dropping lake's level is -0.75, calculated by dividing the total drop in levels (3 feet) by the total time (4 weeks). As the lake's level is dropping, the rate of change is negative.

The question is asking us to find the unit rate of change in the lake's level, which means the amount the level has changed per unit of time. In this case, the time unit is weeks.

The lake has dropped 3 feet over 4 weeks, so to calculate the unit rate of change, we divide the total change (3 feet) by the total time (4 weeks). This results in a unit rate of change of 0.75 feet per week. However, since the lake's level is dropping, this should be a negative number.

So, the correct answer is (c) -0.75.

Answer:

18.4 but io do not know what expression can be used to find out your questions

Step-by-step explanation:

Answer:

A. 1/5 × 92 is the Expression that can be used in order to find 20% of 92.

To find the LCM, you CAN divide the product of the two numbers by the GCF.

This is not a very well-known fact, but it is useful at times, especially when we are asked to calculate both the LCM and GCF.

For example, the GCF of 18 and 48 is 6, by inspection or by factors.

Therefore the LCM of 18 and 48 is 18*48/6=864/6=144.

It works because by definition the GCF is the products of all common factors between the two given numbers.  Dividing the product by the GCF will therefore remove the duplication of the common factors, leaving a number which contains the factors of each of the two numbers, thus a lowest common multiple.

Note that this method is not the only way to find LCM's.

Answer:

The teacher establishes 7 work stations in each of the classrooms.

Step-by-step explanation:

Each work station has 1/16 pounds of clay.

There are two classrooms with the same number of workstations.

The total amount of clay is 7/8

Then, we look for a number of work stations per classroom x, which multiplied by the number of classrooms (2) and multiplied by the amount of clay per work station (1/16) is equal 7/8.

Then we propose the following equation

[tex]\frac{1}{16}(2x) =\frac{7}{8}\\\\ \frac{2}{16}x = \frac{7}{8}\\\\ x = \frac{16 * 7}{8 * 2}\\\\ x = 7[/tex]

Workstations  the teacher set up in each of the classrooms is is mathematically given as

x=7

Question Parameters:
