Answer: The size of the sugar order decreased by 40%.

Step-by-step explanation:

1,090 is 100%

654 is 60% of 1,090 (1,090 ÷ 0.6 = 654)

1,090 - 654 =  436, and 436 is 40% (0.4) of 1,090

1,090 (100%) - 436 (40%) = 654 (60%)

The percent of the decrease in the size of the sugar order is 40%.

The number of additional red marbles to be added to the total 24 marbles present in the bag is 16 marbles.

What is Probability?

From the question, it is given that the,

Number of Red marbles = 8

Number of Yellow marbles = 9

Number of Green marbles = 7

So, the total number of marbles = 8 + 9 + 7 = 24

Let [tex]x[/tex] be the additional number of red marbles added to the bag.

The total number of red marbles after the addition of [tex]x[/tex] red marbles into the bag = [tex]8+x[/tex]

The total number of all marbles after the addition of [tex]x[/tex] red marbles into the bag = [tex]24+x[/tex]

The probability of randomly drawing a red marble is given as equal to [tex]\frac{3}{5}[/tex]

We know that, the probability of randomly drawing a red marble is equal to the ratio of the total number of red marbles to the total number of all marbles.

---> P(R) = n(R)/n(T)

Substituting the given values, we get

3/5 = 8+x / 24+x
---> 5(8+x) = 3(24+x)
---> 40 + 5x = 72+3x

Solving, we get

5x - 3x = 72 - 40
---> 2x = 32
---> x = 16

Therefore, the additional number of red marbles to be added to obtain the required probability is equal to 16.

Answer:

Domain: (-∞, +∞)

Range: [2, +∞)

Step-by-step explanation:

Domain is the "allowable x-values/inputs"

Range is the "possible y-values/outputs when the x-values in the domain are inputted".

From the graph, notice how each end of it extends infinitely to the left and to the right. This means that the domain is infinite and there are no restrictions. Writing it in interval location would look like this:

(-∞, +∞)

Also, notice how the y-values increase from the vertex but do not go below it. That suggests that the range is "lower-bounded" to the vertex, and increases infinitely. Writing it in interval location would look like this:

1. The revised annual depreciation on December 31, 2022, is $3,650.

2. The journal entry to record depreciation on December 31, 2022 is as follows:

Debit Depreciation Expense $3,650

Credit Accumulated Depreciation $3,650

To record the depreciation expense for the year.

3. The balance in Accumulated Depreciation for Equipment on December 31, 2022, is $37,150.

Cost of equipment = $75,000

Purchase date = July 1, 2019

Estimated useful life = 5 years

Salvage value = $8,000

Depreciable amount = $67,000 ($75,000 - $8,000)

Annual depreciation expense = $13,400 ($67,000/5)

Accumulated Depreciation for two and half years to December 2021 = $33,500 ($13,400 x 2.5)

Book value after 2.5 years = $41,500 ($75,000 - $33,500)

New estimated useful life = 10 years

Revised salvage value = $5,000

Revised depreciable amount = $36,500 ($41,500 - $5,000)

Revised annual depreciation expense = $3,650 ($36,500/10)

Answer: 16

Step-by-step explanation:

To *increase* 24 in the ratio 2:3

To *increase* a quantity in given ratio consider new quantity and old quantity.

Formula: New quantity:old quantity=given ratio solution: let us take the new quantity as x, old quantity as 24(given) and given ratio=2:3(given)

-> x:24=2:3

-> x/24=2/3

-> Multiply with 24 on both sides to get x

-> 24*x/24=2/3*24

-> x=16

The coordinates of the image of the point (−9,−3) under the same translation will be (-7,-5).

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that the image of the point (-3, -6) under a translation is (-1, -8).

The coordinate by which the first given condition is translated as,

(-3, -6) - (x,y) =  (-1, -8)

(x,y) = (-3, -6) - (-1, -8)

(x,y) =(-3-(-1), -6-(-8)

(x,y) =(-3+1),(-6+8)

(x,y) =(-2,+2)

The coordinates of the image of the point (-9, -3) are under the same translation obtained as,

=(−9,−3)- (-2,+2)

=(-9-(-2) , (-3-(+2))

The value of x and y in the similar triangles are 10 and 12 respectively.

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

In other words, similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other

The triangles ABC and MPN are similar triangles.

Therefore,

∠A = ∠M

∠B = ∠P

∠C = ∠N

Hence, let's find x and y using the proportion as follows:

Markus' biweekly earnings (gross pay every two weeks) are $2,727.16.

The annual gross pay can be divided by 26 to get the biweekly earnings.

Another way to compute the biweekly earnings is by adding up the withholding taxes, deductions, and net earnings.

In practice, the net earnings are equal to the gross pay less withholding taxes and deductions.

Annual gross pay = $65,500

Payment period = biweekly (1st and 15th every month)

Social Security = $156.19

Medicare =            36.53

Federal tax  =     445.96

Total withholding = $636.68

Retirement = $45

Health Insurance = $200

Total deductions = $245

Net Earnings = $1,845.48

A equation of line with a slope of -7/16 passes through the point (-16, 7) is y = (-7/16)x

We know that the formula for the slope-point form of equation of line:

(y - y1) = m(x - x1)

Let (x1, y1) = (-16, 7)

and slope m = -7/16

Using above formula,

(y - 7) = (-7/16)(x - (-16))

y - 7 = (-7/16)(x + 16)

y = -7/16x - 7 + 7

y = (-7/16)x

This equation is slope-intercept form (y = mx + c) with slope -7/16 and y-intercept 0.

Step-by-step explanation:

Let's name the triangle ABC.

Assuming these are the 3 sides of the triangle, and naming them a,b,c.

a=5 cm

c=12 cm

Semi perimeter of the triangle ABC= s = (a+b+c)/2

s=(5+13+12)/2 =30/2=15.

Area of triangle ABC= √(s * (s-a)*(s-b)*(s-c)

                                  =  √(15*(15-5)*(15-13)*(15-12)

                                  =  √15*10*2*3

What is digit?
A positional numeral system uses a single symbol, such as "2," or a combination of symbols, such as "25," to represent numbers. This single symbol is known as a numerical digit. The word "digit" derives from the fact that ten fingers (Latin: digiti) on each hand correspond to the ten numeral symbols used in the base-10 system, or decimal digits (Old Latin: decem, meaning "ten"). The absolute value of the base determines how many different digits are necessary for a given numeral system with just an integer base. For instance, the binary system (base 2) only needs two digits, whereas the decimal system (base 10) necessitates ten digits (0 through 9). (0 and 1).

The digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
