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.

Step-by-step explanation:

Answer:

The answer is 8 sides.

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.

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]

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

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

x=7

Question Parameters:

An art teacher has a total of 7/8 pound of clay.

The teacher puts 1/16 pound of clay at each workstation.

The teacher sets up an equal number of workstations in each of 2 classrooms

Generally the equation for the  workstations is mathematically given as

1/16(x)=7/8

x=16*7/(8*2)

x=7

Therefore,workstations  the teacher set up in each of the classrooms is

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.

(-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

Step-by-step explanation:

distributive property because you are distributing the 2

part A:

company a

30m+15

m= matress

company b

28m+21

m=matresses sold

part B:

company a

30(6)+15

195$

company b

28(6)+21

189$

company B charges less

part C:

company a

30(3)+15

105$

company b

28(3)+21

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.

Answer: non-terminating decimals

Integers and whole numbers can be converted to fraction form. Example, the whole number 3 can be written as 3/1 which is rational. A rational number is any fraction of whole numbers (eg: 7/19). The denominator can never be zero.

All repeating decimals can be converted into a fraction. A number like 0.8888 with the 8s repeating forever converts to the fraction 8/9, which is rational

Non-terminating decimals are decimals that go on forever. If there is no pattern to the decimal sequence, then the decimals don't repeat and the number cannot be converted to a rational number. Something like pi = 3.14159... has no pattern to the decimal sequence. Therefore, a number like pi is irrational, which literally means "not rational", so numbers like pi aren't rational and are not part of the set of rational numbers.

Non terminating and non repeating decimals cannot be written in fraction from . So they are not included in set of rational numbers.

Given :

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.

First you need to subtract 16 from each side.
