Final answer:

This explanation provides a step-by-step process for figuring out adjusted gross income (AGI) and taxable income, based on given values for gross income, adjustments, exemptions, and deductions in three examples.

Explanation:

In context of tax calculations, your adjusted gross income (AGI) is calculated by taking your gross income and subtracting any adjustments. Taxable income is calculated by subtracting exemptions and deductions from your AGI.

Example 1:Gross Income: $30,856 minus Adjustments: $750 equals AGI: $30,106. Then, AGI: $30,106 minus Exemptions: $8,200 minus Deductions: $2,300 equals Taxable Income: $19,606.Example 2:Gross Income: $67,890 has no Adjustments. Hence, its AGI is $67,890. Then, AGI: $67,890 minus Exemptions: $24,600 minus Deductions: $1,469 equals Taxable Income: $41,821.Example 3:Gross Income: $19,723 minus Adjustments: $255 equals AGI: $19,468. Then, AGI: $19,468 minus Exemptions: $8,200 minus Deductions: $1,430 equals Taxable Income: $9,838.

D. 95,040

Answers

Kidjov the answer I came up with for you is 792 I hope this helps

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Total number of shirts purchased for her team = 12

Number of shirts places in the first bag = 5

We need to find the number of ways a group of 5 shirts be placed in that first bag.

We will use "Combination" to find the number of different ways :

As we know the formula for Combination.

[tex]^nC_r=\frac{n!}{r!\times (n-r)!}\\\\here, n=12\\\\r=5\\\\So,\ it\ becomes,\\\\^{12}C_5=\frac{12!}{5!\times 7!}\\\\=\frac{12\times 11\times 10\times 9\times 8}{5\times 4\times 3\times 2}\\\\=792[/tex]

Hence, there are 792 ways to do so.

Therefore, Option 'C' is correct.



Below is a piece of a local pizza place menu where Jacob works.

Large Cheese Pizza $14.85
Large Supreme Pizza $16.90
Cheese Sticks $5.99
Dessert Pizza $6.99


4. The largest order last Saturday was from a basketball team that ordered 5 large supreme pizzas, 5 large cheese pizzas, 5 orders of cheese sticks and 5 dessert pizzas. Jacob said the total was about $225. Is this reasonable? Justify your response using estimation. If the answer is not reasonable, identify the error and then calculate the correct solution.

Answers

this is reasonable, the total of everything would be 223.65.. which rounds up to 225.

Jacob's estimate of $225 for the basketball team's order is reasonable. Our calculations show a total estimated cost of $223.75, which is close to Jacob's estimate.

To determine if Jacob's estimated total of $225 for the basketball team's order is reasonable, we can perform a quick estimation.

First, let's list the items ordered:

5 large supreme pizzas at $16.90 each5 large cheese pizzas at $14.85 each5 orders of cheese sticks at $5.99 each5 dessert pizzas at $6.99 each

Next, we will estimate the total cost for each category:

5 large supreme pizzas: $16.90 x 5 = approximately $84.505 large cheese pizzas: $14.85 x 5 = approximately $74.255 cheese sticks: $5.99 x 5 = approximately $305 dessert pizzas: $6.99 x 5 = approximately $35

Now, summing these estimates: $84.50 + $74.25 + $30 + $35 = $223.75

Thus, Jacob's estimate of about $225 is reasonable, as our estimation shows a total of $223.75, which is close to his figure.

DE has endpoints D 0, 3 and E 0, 12 find the length of DE to the nearest tenth

Answers

The answer is 9 because the distance formula is square root of (x2-x1)^2 + (y2-y2)^2

Answer:  The length of side DE is 9 units.

Step-by-step explanation:  Given that the co-ordinates of the end-points of DE are D(0, 3) and E(0, 12).

We are to find the length RT of the polygon.

We know that

the length of a line segment with endpoints P(a, b) and Q(c, d) is equal to the distance between the points P and Q.

By distance formula, the distance between P(a, b) and Q(c, d) is

[tex]D=\sqrt{(c-a)^2+(d-b)^2}.[/tex]

So, the distance between D(0, 3) and E(0, 12) is given by

[tex]DE=\sqrt{(0-0)^2+(12-3)^2}=\sqrt{9^2}=9.[/tex]

Thus, the required length of DE is 9 units.

(a) BC = 40

(b) GF = 15

(c) CD = 45

(d) KM = 37.5

=========================================================

Explanations:

Part (a)

GF is a midsegment of triangle ABC, so GF is half that of the parallel base AC
AC = 30 so GF = (1/2)*AC = 0.5*30 = 15

--------------------------
Part (b)

For similar reasons as part (a), FB if half that of BC. This leads to FB = FC

FB = FC
FC = 20
since FB = 20

Now use the segment addition postulate
BC = BF + FC
BC = 20 + 20
BC = 40

Note: FB is the same as BF. The order of the letters does not matter.

--------------------------
Part (c)

GF = AD are the same length because of the single tickmark

GF = 15 so AD = 15

use the segment addition postulate
CD = CA + AD
CD = 30 + 15
CD = 45

--------------------------
Part (d)

EG = 15 since GF = 15 (and EG = GF by the single tickmark)

use the segment addition postulate
EF = EG + GF
EF = 15 + 15
EF = 30

The length of KM is the average of the base lengths EF and DC, since KM is a midsegment of the trapezoid

KM = (EF+DC)/2
KM = (30+45)/2
KM = (75)/2
KM = 37.5

The measures are:

(a) BC = 20 mm

(b) GF = 10 mm

(c) CD = 10 mm

(d) KM = 10 mm

To find the measures you're looking for in the given diagram, we'll use properties of midsegments in triangles and trapezoids.

First, let's establish some properties:

In triangle ABC, FG is the midsegment, so FG is parallel to BC and half the length of BC.

In trapezoid CDEF, KM is the midsegment, so KM is parallel to EF and half the length of EF.

EF is parallel to KM and also parallel to DC.

Now, let's find the measures:

(a) BC:

Since FG is the midsegment of triangle ABC, FG is parallel to BC, and FG is half the length of BC. Therefore, BC = 2 * FG.

(b) GF:

GF is the midsegment of triangle ABC, so it's half the length of BC. Thus, GF = BC / 2.

(c) CD:

Since EF is parallel to DC and KM is the midsegment of trapezoid CDEF, CD is also half the length of EF. Therefore, CD = EF / 2.

(d) KM:

KM is the midsegment of trapezoid CDEF, so it's half the length of EF. Thus, KM = EF / 2.

Now, let's find the specific values using the information given:

Given values:

BC = 20 mm (from the diagram).

EF = 20 mm (since BC is parallel to EF in the same trapezoid).

(a) BC:

BC = 2 * FG

BC = 2 * GF (since GF is half the length of BC)

BC = 2 * (BC / 2) (substituting the given value for BC)

BC = BC

(b) GF:

GF = BC / 2

GF = 20 mm / 2

GF = 10 mm

(c) CD:

CD = EF / 2

CD = 20 mm / 2

CD = 10 mm

(d) KM:

KM = EF / 2

KM = 20 mm / 2

KM = 10 mm

Use the rules of significant figures to answer the following question: 43.5694•22.07

Answers

Remember that in mathematical operations with significant figures the answer must reflects the reliability of the least precise operation. In other words the answer will have the same amount of significant figures as the number with least significant figures involved in the mathematical operation.
To solve this problem we are going to use the multiplication of significant figures rule, which says that the least number of significant figures in the numbers you are multiplying determines the number of significant figures in the answer. 
But, to apply this rule, we first need to understand how to count significant figures in a number. To do this we are going to use tow additional rules for significant figures: the non-zero rule, and the zero in between rule. The first says that non-zero digits are always significant figures, and the second one that any zeros between two significant digits are significant figures.
So, lets apply this to our numbers:
[tex]43.5694[/tex] does not has any zeros, so using the non-zero rule we can conclude that it has 6 significant figures.
[tex]22.07[/tex] has one in between zero, so using the non-zero rule and the zero in between we can conclude that is has 4 significant figures. 
Since the answer is determined by the number with least significant figures, our answer will have 4 significant figures.

Answer:
First option

Explanation:
Translating a point four units downwards means that:
the x-coordinate would stay the same
the y coordinate will be decreased by 4

Now, for the given points:
Point R (-3,1)
x coordinate o R' = x coordinate of R = -3
y cordinate of R' = y coordinate of R - 4 = 1 - 4 = -3
R' is (-3 , -3)

Point S (-2,3)
x coordinate of S' = x coordinate of S = -2
y coordinate of S' = y coordinate of S - 4 = 3 - 4 = -1
S' is (-2 , -1)

Point T (2,3)
x coordinate of T' = x coordinate of T = 2
y coordinate of T' = y coordinate of T - 4 = 3 - 4 = -1
T' is (2 , -1)

Point U (3,1)
x coordinate of U' = x coordinate of U = 3
y coordinate of U' = y coordinate of U - 4 = 1 - 4 = -3
U' is (3 , -3)

Comparing the calculated values with the given ones, we will find that the correct choice is the first one.

Hope this helps :)

Answer:

The correct option is 1.

Step-by-step explanation:

The vertices of quadrilateral RSTU are R (-3, 1) , S (-2, 3) , T (2, 3) , and U (3, 1).

It is given that quadrilateral RSTU translate four units down to get R'S'T'U'.

The relation between the vertices of RSTU and R'S'T'U' is

[tex](x,y)\rightarrow (x,y-4)[/tex]

The vertices of R'S'T'U' are

[tex]R(-3,1)\rightarrow R'(-3,1-4)=R'(-3,-3)[/tex]

[tex]S(-2,3)\rightarrow S'(-2,3-4)=S'(-2,-1)[/tex]

[tex]T(2,3)\rightarrow T'(2,3-4)=T'(2,-1)[/tex]

[tex]U(3,1)\rightarrow U'(3,1-4)=R'(3,-3)[/tex]

The  vertices of R'S'T'U' are R' (-3, -3) , S' (-2, -1) , T '(2, -1) , and U' (3, -3).

1) To find a square root means to find the number that multiplied by itself gives you the given number. Since both a positive number multiplied by itself and a negative number multiplied by itself give you a positive number, we can say that every positive number has two square roots, one positive and one negative.

In order to find the square root of 0.0064, you need to think the number without the comma, in your case then 64. The square root of 64 is 8 (indeed 8x8=64).

You know need to decide how many decimals your root needs to have: since the given number had 4 decimals, you have to halve, therefore your root will have 2 decimal: 0.08

The square roots you are looking for are +0.08 and -0.08

2) To find the real-number root means to find the number that gives you real roots if square rooted. Since negative numbers give you imaginary numbers if square rooted, your answer has to be 1.1, the only positive number.

a.) Show the results of your calculations for points A, B, C and D from the reflection.

b.) Show the results of your calculations for points A, B, C and D from the translation.

Let's start b writing down coordinates of all points:
A(0,0,0)
B(0,5,0)
C(3,5,0)
D(3,0,0)
E(3,0,4)
F(0,0,4)
G(0,5,4)
H(3,5,4)

a.) When we reflect over xz plane x and z coordinates stay same, y coordinate  changes to same numerical value but opposite sign. Moving front-back is moving over x-axis, moving left-right is moving over y-axis, moving up-down is moving over z-axis.

The area of this circle is 42π m².

What is the area of a 60º sector of this circle?

6π m²

7π m²

14π m²

21π m²

Answers

A full circle is 360°, so a 60° circle is 1/6th of the area.

1/6th of 42π m² is 7π m², so answer B.

Using proportions, it is found that the area of a 60º sector of this circle is of [tex]7\pi[/tex] m².

Proportions:This question is solved by proportions, using a rule of three.An entire circle is of 360º, which has an area of [tex]42 \pi[/tex] m²? Which is the area equivalent to a sector of 60º?

The rule of three is:

360º - [tex]42 \pi[/tex] m²

60º - x m²

Applying cross multiplication:

[tex]360x = 60 \times 42\pi[/tex]

[tex]x = \frac{60 \times 42\pi}{360}[/tex]

[tex]x = 7\pi[/tex]

The area of a 60º sector of this circle is of [tex]7\pi[/tex] m².
