Jasen packs 10 boxes of computer parts in 2.5 hours and Ben packs 12 boxes in 3 hours. how long will Jasen and Ben take to pack 100 boxes of computer parts together?

The Answer for this is - 12.5 hours

I need the proper working

Answers

let x be the amount of time needed for packing one box.
2.5x = 10
x = 10/2.5
x = 4 minutes per box

3x = 12
x = 12/3
x = 4 minutes per box

Then, either Jasen and Ben need 4 minutes to pack a box.

Each box needs 4 minutes of packing, so 100 boxes divided by 4 is 25. But since for one person it needs 25 then for two people it’s half the time needed so it is 25/2 which is 12.5

Answer: 24 over 2 squared equals 50 minus 6 squared minus 8

56 divided by 8 plus 3 squared equals 2 times 2 cubed

Step-by-step explanation:

24/2^2 = 50-6^2 - 8

24/4 = 50-36-8

6 = 14-8

6=6

39-3*6 = 6*10/4 + 4

Answers

Answer: on the toss side the missing number is 50 and on the dollar side the missing number is 4.

On the dollars side I subtracted 8 from 12 and got 4. 4 doubled is 8 so then I doubled 25 and got 50. every 25 rings costs 4 dollars so as you increase by 25 you also increase by 4. For graphing you treat tosses like the X value and you treat the dollars as the Y value.

The equation c equals one third times s represents the proportional relationship between the number of bags of cement (c) and the number of bags of sand (s) required to make concrete. A graph of this relationship is shown.

Which statement is true?

The proportional relationship is graphed correctly.
The graph does not show a proportional relationship.
Bags of Sand should be on the x-axis, and Bags of Cement should be on the y-axis.
The axes are labeled correctly with the independent and dependent variables.

Answers

The correct statement is option (C) Bags of Sand should be on the x-axis, and Bags of Cement should be on the y-axis.

The equation c equals one third times s

c = (1/3)s

Where c is the number bags of cements

s is the number of bags of sands required to make concrete.

We can see that the number of bags of cements is directly proportional to the number of bags of sands required to make concrete

Here number of bags of sand is independent variable and number of bags of cement is dependent variable.

To plot the relationship in the graph the number of bags of sand should be on the x-axis, and Bags of Cement should be on the y-axis

Hence, the correct statement is option (C) Bags of Sand should be on the x-axis, and Bags of Cement should be on the y-axis.

y = 3x Domain:{−4, −2, 0, 2}
Can someone EXPLAIN how to do it?
I really need the concept with how to graph if possible

Answers

Let’s start with defining a function. A function relates two variables (x, y), where y is dependent on x. For example, in the given function: y=3x, if x=2, then y=3(2) which is y=6. But, if x=4, then y=3(4) which is y=12. You see how multiplying 3 by different x-values gives us different y-values? This is what a function does, where x must be known to find y. So, how does this apply to graphing?

When graphing a function, the x-values are called input, and the y-values are called output. This is because the x-values Rae the values you’re inputting into the function which will output a y-coordinate. A function’s domain is the set of all x-values that satisfy the function, meaning they are the values that provide a y-coordinate. The range is the set of all y-values produced from the x-values, so the range is the set of outputs when x is a specific input. To graph a function, we graph points as an ordered pair. Remember, an ordered pair takes the form (x, y); it is the pair of an x-coordinate that relates a y-coordinate. So, we plot points on a coordinate plane. The idea is that x-coordinates, or input, are located first; these are the coordinates that shift laterally (left to right). Then, we locate the corresponding y-value, or input, for that x-value, and graph the point. So, we first travel along the x-axis, then rise or drop following the y-axis and plot the point.

So, let’s look at the function y=3x. We are given the domain: remember the domain is the set of all x-values. So, the domain values are the values we plug in for x. So, we will plug in -4 for x:

y=3(-4)

y=-12

Our point is (4, -12) because our input (x) is 4 and output (y) is -12. This means we travel a distance of 4 units along the x-axis, then down down units following the y-axis.

The process repeats for the remaining domain values:

y=3(-2)

y=-6

The point is (-2, -6), so we travel 2 units to the left (because the value is -2, not 2), then down 6 units.

y=3(0)

y=0

The point is (0, 0), so we travel no spaces left or right and no spaces up or down.

y=3(2)

y=6

The point is (2, 6), so we travel 2 units to the right (2 is a positive value) and 6 units up.

That’s how a function works! X-values are input into the equation and from there, you simplify and solve for y, the output. These points are graphed as a coordinate pair (x, y), so you travel lateral “x” units and vertically “y” units, then plot the point. Then, you connect the points with a line.

3. 1.25 kg :500 g in simplest form
4. 75 cents : $2
5. 400 m : 2 km

Answers

Answer:Here we will learn how to make the ratio in simplest form.

1. A ratio between two quantities of same kind and in the same units is obtained on dividing one quantity by the other and has no unit. The ratio is independent of the units used in the quantities compared.

2. The ratio must always be expressed in its simplest form or in its lowest terms.

A ratio is said to be is the simplest form or in the lowest term if two quantities of a ratio (i.e., antecedent and consequent) have no common factor (i.e. antecedent and consequent are co-prime) other than 1 (or their HCF is 1.)

For example:

(i) The ratio between 36 kg and 24 kg = (36 kg)/(24 kg)

= 36/24, [both numerator and denominator are divided by 12]

= 3/2

= 3 : 2.

(ii) The ratio between 5 kg and 15 kg = (5 kg)/(15 kg)

= 5/15, [both numerator and denominator are divided by 5]

= 1/3

= 1 : 3.

3. If in a ratio the number or quantities are of the same kind but in different units, then we must convert them number or quantities into same unit. Generally, the bigger unit of the ratio is converted into smaller unit.

For example:

(i) The ratio between 800 g and 1.2 kg = (800 g)/(1200 g)

= 800/1200, [since 1.2 kg = 1.2 × 1000 gm = 1200 gm]

= 8/12, [both numerator and denominator are divided by 4]

= 2/3

= 2 : 3.

(ii) The ratio of 5 cm and 60 mm = (50 mm)/(60 mm), [since 5 cm = 5 × 10 mm = 50 mm]

= 50/60, [both numerator and denominator are divided by 10]

= 5/6

= 5 : 6.

4. If each term of a ratio is multiplied or divided by the same non-zero number (quantity), the ratio remains the same.

For example:

The ratio of 18 and 24= 18 : 24 = 18/24

Now, 18/24 = (18 × 6)/(24 × 6) = 108/144  or, 18 : 24 = 108 : 144.

Again, 18/24 = (18 ÷ 6)/(24 ÷ 6) = 3/4 or, 18 : 24 = 3 : 4.

5. The order of the quantities (terms) in a ratio (P : Q) is important. By reversing the antecedent and the consequent of a ratio, a different ratio is obtained (i.e., Q : P).

For example:

(i) The ratio 5 : 7 is different from the ratio 7 : 5.

(ii) 6 : 11 is different from 11 : 6.

The different types of examples along with the explanation will help us how we usually express the ratio in simplest form.

Nadia is a stockbroker. She earns 11​% commission each week. Last​ week, she sold ​$4,500 worth of stocks. How much did she make last week in​ commission? If she averages that same amount each​ week, how much did she make in commission in​ 2011?

Answers

Last week she did $495

Answer:

a). Nadia made a total of $825 last week in commission sales

b). The total amount Nadia in commission in 2011=$42,900

Step-by-step explanation:

Step 1

Express the amount in commission she earns from her sales as follows;

C=S×r

where;

C=commission earned

S=total value of stock sales

r=commission rate

In our case;

C=unknown

S=$7,500

r=11%=11/100=0.11

replacing;

C=11% of 7,500

C=(11/100)×7,500

C=0.11×7,500=825

Nadia made a total of $825 last week in commission sales

b). To express the total amount she made in 2011, we derive the formula below;

Total amount (2011)=Average weekly commission×number of weeks in 2011

where;

Average weekly commission=$825

number of weeks in 2011=52

replacing;

Total amount (2011)=(825×52)=42,900

The total amount Nadia in commission in 2011=$42,900
