Therefore, the total mass of all bags of beads is 19.27 grams

Given masses of three bags of beads as

Mass of beads in bag1 = 10.3 grams

Mass of beads in bag2 = 5.23 grams

Mass of beads in bag3 = 3.74 grams

We have to calculate the total mass of all the beads as below

The total mass of all bags of beads = mass of bag1 + mass of bag2 + mass of bag3

                                                           = 10.3 + 5.23 + 3.74

A strategy for teaching division is by repeated subtraction. It involves repeatedly subtracting the same integer from a big number until the result is zero. It is a fantastic approach to teach kids about division. A technique called repeated subtraction, commonly referred to as division, removes an equal amount of items from a group.

Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.

Given that,

The difference between 4 and the sum of a number and is equal to twice that number.

Repeated subtraction is a method for teaching division. Until the result is zero, the same integer must be repeatedly subtracted from a large number. Repeated subtraction, sometimes known as division, is a method that takes an equal number of elements out of a group.

Division's opposite is multiplication. If 3 groups of 4 total up to 12, then 4 are in each group when 12 is divided into 3 equal groups. The fundamental goal of division is to produce equal groups or to determine how many individuals are in each group following a fair distribution.

x×4+4=2x-4

Subtracting 4 on both sides

4x+4-4=2x-4-4

4x=2x-8

Now, substracting 2x from both sides

4x-2x=2x-8-2x

2x=-8

x=-4

Answer:

Step-by-step explanation:

Step 1: We must locate the slope, by using the slope formula, which is:

[tex]\frac{y2-y1}{x2-x1}[/tex]

When we plug it in we get:

[tex]\frac{-2-10}{9-3}[/tex]

Which simplifies to a -2

Step 2: We must plug in our values in the point-slope formula which is:

[tex]y-y1=m(x-x1)[/tex]

We can plug in (3,10) or (9,-2). It doesn't matter which one, we'll end up with the same answer. For this example, we'll use (3,10)

When we plug in our values we will get:

[tex]y-10=-2(x-3)[/tex]

Step 3: Now we just need to put our equation in slope-intercept form

[tex]y-10=-2(x-3)[/tex]

[tex]y-10=-2x+6\\y=-2x+16[/tex]

Therefore, our answer is [tex]y=-2x+16[/tex]

A ratio shows us the number of times a number contains another number. The area of the TV will be 729 inches².

A ratio shows us the number of times a number contains another number.

Given that the aspect ratio of the 36-inch tv is 16:9. Therefore, the width of the TV will be,

Length of the TV / Width of the TV = 16 : 9

36 inches / Width of the TV = 16 : 9

Width of the TV = 20.25 inches

Now, the area of the TV will be,

Area = Length of the TV × Width of the TV

        = 36 inches × 20.25 inches

        = 729 inches²

Answer:

A weekly salary is a function of the hourly pay rate and the number of hours worked

Step-by-step explanation:

a function is a map assigning values of a result or solution set to values of a set of initial or starting values.

we typically name these starting values x and the solution values f(x) or y (the results "created" out of x).

we often say

y = f(x)

and provide an expression or table to explain the logic of the mapping between x and f(x).

the only rule to be a function and not just a general relationship between these 2 sets :

every value in the set of starting values must have exactly one assigned solution value. not 0, not 2 (or more). one and only one.

but yes, different values of x can have the same assigned solution value. that is not a problem for a function. it just cannot be the other way around. there cannot be different solution values assigned to the same value of x.

so, a typical example of a function is a line.

e.g.

y = f(x) = 5x + 12

for every value of x you could think of (and everything else) there is exactly one result value calculated.

or the score board in a sports event :

athlete 1 : 12 points

athlete 2 : 24 points

athlete 3 : 20 points

athlete 4 : 22 points

...

the athletes are the "x". and their associated points the "f(x)" or "y".

no athlete is listed multiple times with different scores.

a typical example of not being a function is a circle. for almost every value of x inside the circle (that means for almost every point of the horizontal diameter of the circle) there are 2 values of y (that means points on the arc of the circle) : one above and one below the diameter.

or a strange score board like

athlete 1 : 12 points

athlete 2 : 24 points

athlete 3 : 20 points

athlete 2 : 22 points

athlete 4 : 22 points

...

athlete 2 is listed twice with 2 different scores.

so, this is therefore not a function.

Answer: the slope would be 7

Step-by-step explanation:

The reasonable domain of the given situation is 0≤ x ≤2 that is 0 to 2 hours.

We see that x is represented as the number of phone hours used, therefore it has to be a number larger or equal to zero, but not a negative number. So, on one end we have that the number of phone hours used (x) must be larger or equal to zero. On the other hand, when the battery goes to zero, there are no more phone hours to use. We can find what is that other limit by making the battery percent (y variable) equal to zero, and solve the equation for x, thus giving us the upper limit of usable phone hours:

=> y = 0 = 100 - 50x

=> 100 = 50x

=> x = 100/50

=> x = 2

Therefore, the phone can be used for a maximum of 2 hours and the situation may be written as 0≤ x ≤2.

Step-by-step explanation:

The greatest number with 2 decimal places that can be rounded to 13.9 is 13.94.

Answer: 13.94 seconds

The announcer said that Ingrid has won the race in 13.9 seconds, then the slowest time she could have run is 13.94 seconds.

Something similar to something else but not precisely the same is called an approximation. By rounding, a number can be roughly estimated.

By rounding the values in a computation before carrying out the procedures, an estimated result can be obtained.

13.94 is the largest number that can be rounded to the nearest two decimal places and be equal to 13.9.

Because after the second decimal, that is 4 the number has to increase as per the rules of approximation. That's why the number 13.94 up to two decimal places is correct.

The segment joining the midpoints of the diagonals of a trapezoid is parallel to the bases

From the figure, we have the following coordinates

B = (a, 0)

D = (d, c)

The midpoint of line segment BD is calculated as

BD = 1/2 * (x1 + x2, y1 + y2)

So, we have

BD = 1/2 * (a + d, 0 + c)

This gives

BD = ((a + d)/2, c/2)

Also, we have:

Lines MN and AB are horizontal lines

This means that they have a slope of 0

i.e.

Slope of AB = Slope of MN = 0

Parallel lines have equal slope

Hence, the segment joining the midpoints of the diagonals of a trapezoid is parallel to the bases

The range of values for the expressions are given by these following compound inequalities:

A compound inequality is a combination of multiple inequalities, at least two, involving operations such as and and or, explained below.

Hence one example of a compound inequality is:

a ≤ x ≤ b.

Which is read as follows:

x is greater or equal than a and less or equal than b.

The smallest possible value is when both a and b are at their lower bounds, hence:

a + b = 2 + 1 = 3.

The greatest possible value is when both a and b are at their upper bounds, hence:

5 + 2 = 7.

Then the range is:

3 < a + b < 7.

Since the ranges of a and b are open intervals, the ranges of the operations will also be composed by open intervals.

The smallest possible value is when both a and b are at their lower bounds, hence:

a x b = 2 x 1 = 2.

The greatest possible value is when both a and b are at their upper bounds, hence:

a x b = 5 x 2 = 10

Then the range is:

2 < ab < 10.

The smallest possible value is when a is at it's lower bound and b is at it's upper bound, hence:

2 - 2 = 0

The greatest possible value is when a is at it's upper bound and b is at it's lower bound, hence:

5 - 1 = 4.

Hence the range is:

0 < a - b < 4.

The smallest possible value is when a is at it's lower bound and b is at it's upper bound, hence:

2/2 = 1.

The greatest possible value is when a is at it's upper bound and b is at it's lower bound, hence:

Step-by-step explanation:

Marvin Co. sells a total of 12 flashlights and 84 pens

Price of pen sold by Marvin Co. = $6

Price of flashlight sold by Marvin Co. = $10

Total sales = $624

Let the number of flashlights be x and the number of pens be y

Formulating the equations:

10x + 6y = 624

It is given that customer bought 7 times as many pens as flashlights, therefore:

y = 7x

Putting y = 7x in the equation we get,

10x + 6(7x) = 624

10x + 42x = 624

52x = 624

x = 12

So, the number of flashlights sold is 12 and the number of pens sold is 84

The equation of the line tangent to the curve is y = 19 · x - 7.

In this problem we need to find the equation of a line tangent to the function f(x) = (√x + 5) · (x² + x) for x = 1, that is, a line that only passes through one point of the entire curve. The equation of the line is introduced below:

y = m · x + b

Where:

The slope of the line can be found by evaluating the first derivative of f(x) for x = 1:

f'(x) = (1 / 2√x) · (x² + x) + (√x + 5) · (2 · x + 1)

f'(1) = (1 / 2) · 2 + 6 · 3

f'(1) = 1 + 18

f'(1) = 19

The y-coordinate of the curve is:

f(1) = (√1 + 5) · (1² + 1)

f(1) = 6 · 2

f(1) = 12

Lastly, we determine the intercept of the tangent line:

b = y - m · x

b = 12 - 19 · 1

b = - 7

The equation of the line tangent to the curve is y = 19 · x - 7.
