Answer:

Real number

Step-by-step explanation:

18.62 is a Real number. A real number is just a number that is either an integer, decimal or anything like that.

[tex]\tt Step-by-step~explanation:[/tex]

[tex]\tt Area:[/tex]

To solve for the area of a triangle, we multiply the length and height, then divide that by two. L = 10. H = 7.

[tex]\tt 10*7=70\\70/2=35\\35=A[/tex]

[tex]\tt Perimeter:[/tex]

[tex]\tt Step~1:[/tex]

To solve for the perimeter, or edges, of the triangle, we need to use the Pythagorean Theorem: a² + b² = c² to solve for the third side. We already know two measures: 10 and 7. Now we need to square them, add them together to get c², then take the root of that number.

[tex]\tt 7^2=49\\10^2=100\\100+49=\sqrt{149}\\\sqrt{149[/tex]

We cannot simplify √149, so we either leave it, or round it.

[tex]\tt \sqrt{149}\\12.2066[/tex]

This is rounded to the nearest 10,000.

[tex]\tt Step~2:[/tex]

Now that we have the measure of the longest side, we can add all three sides together to get the perimeter of the triangle.

[tex]\tt 10+7+\sqrt{149}=17+\sqrt{149}=P\\Rounded~to~the~nearest~1,000th:~29.207=P[/tex]

[tex]\large\boxed{\tt Our~final~answer: ~A=35,~P=17+\sqrt{149}}[/tex]

Answer: x = 75/2

Step-by-step explanation:

First, separate the 1/3d and 10 by subtracting 1/3d to the right side so the equation is now: 10 = 3/5d - 1/3d

Next, Make the two fractions have a common denominator: (3/5 = 9/15) and (-1/3 = -5/15) and solve to get 4/15x

Then, your equation should be 10= 4/15x

So now multiply the 10 by 4/15's reciprocal (15/4) to get the variable x by itself: 10 × 15/4 or

(10×15) / (4×1) to get x = 150/4 now simplify

4 can go into 150 twice so the simplified answer is 75/2 or 37.5 in decimal form

Question 1:

We are going to add.

1/5 + 1/2

2/10 + 5/10

7/10

Note that we are going DOWN so the number will be negative.

Therefore, the answer is A.) -7/10

Question 2:

We are going to subtract.

4 1/2 - 1 2/3

9/2 - 5/3

27/6 - 10/6

17/6 or 2 5/6

Note that we are still BELOW sea level so the number will be negative.

Therefore, the answer is C.) -2 5/6

Question 3:

We are going to subtract.

2 2/3 - 1 1/5

8/3 - 6/5

40/15 - 18/15

22/15 or 1 7/15

Therefore, the answer is B.) 1 7/15

Answer:

The image of [tex]D[/tex] must lie on the ray [tex]BA[/tex], since ray [tex]BA[/tex] is antiparallel to ray [tex]BD[/tex]. That is, the angle between both rays is 180 degrees.

Step-by-step explanation:

Let be [tex]D'[/tex] the image of [tex]D[/tex] such that [tex]D[/tex] is rotated 180 degrees counterclockwise with [tex]B[/tex] as center of rotation.

[tex]D'[/tex] must lie on the ray [tex]BA[/tex], since ray [tex]BA[/tex] is antiparallel to ray [tex]BD[/tex]. That is, the angle between both rays is 180 degrees.

Answer:

The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.

Answer:

If the line RS has been rotated 90 degrees, then VU will be perpendicular to RS and the two slopes must be opposite and reciprocal, i.e. product of the two slopes will equal -1.

As a verification, we find the locations of V and U from rotations of R & S.

(actually, the triangle had been rotated -90°, 90 ° clockwise)

Step-by-step explanation:

Slope RS, m1:

Slope VU, m2

Hence m1*m2=1*-1=-1, meaning that m1 and m2 are opposite (in sign) and are reciprocal to each other, as expected

The lines RS and VU have the opposite and reciprocal slopes because                               Slope of QRS is 1, where as Slope of TVU is -1

Slope of a triangle represents the angle that are formed between positve X-axis moving anticlockwise towards y-axis.

RQ=3

SQ=3

 slope (Tan∅)=[tex]\frac{perpendicular}{base}[/tex]

                       =RQ/SQ

                        =3/3 =1

           TanФ=45°

UT=3

VT=-3

 slope (Tan∅)=[tex]\frac{perpendicular}{base}[/tex]

                       =UT/VT

                        =3/-3 =-1

           TanФ=135°

Slope of QRS is 1, where as

Slope of TVU is -1

∴ RS and VU have the opposite and reciprocal slopes.

Answer:

This will be rational.

Step-by-step explanation:

Keep in mind that a rational number is (of a number, quantity, or expression) expressible, or containing quantities that are expressible, as a ratio of whole numbers. When expressed as a decimal, a rational number has a finite or recurring expansion.

Answer:

n = -20

Answer:

y= 52, x = 5

Step-by-step explanation:

since A = 52 degrees its the same on the otherside

so y= 52

to work out x:

(14x + 6) + 52 + 52 = 180 (sum of all angles in a triangle)

(14x + 6 ) + 104 = 180

14x +6 = 76

14x = 70

x = 5

The residual plot give you the most detailed graphical appropriatness

A plot or graph shows the relationship between related variables.

The best graphic to use is the residual plot.

The best graph to plot a linear regression is the scatter plot, because it shows a clear relationship between the variables that are being compared.

From the list of given options, we can say that the residual plot is the best plot to use by the consultant.

This is because, the residual plot is a form of scatter plot that shows the difference between the observed value and the actual value.

In this case, the observed value would be the number of units sold, while the actual value would be the expected number of units to be sold.

Hence, option (c) answers the question.

[tex]\tt Step-by-step~explanation:[/tex]

To solve for x, we have to remember to isolate the variable.

[tex]\tt Step~1:[/tex]

For 1/2, we can make that 0.5, since their values are equivalent. Our equation:

[tex]\tt (0.5)(6x+3)=7-(3x+1)[/tex]

Let's distribute the 0.5 first.

[tex]\tt 0.5*6x=3x\\0.5*3=1.5[/tex]

[tex]\tt Step~2:[/tex]

Now, let's simplify the right side of the equation. We have to distribute the negative to 3x and 1.

[tex]\tt -1*3x=-3x\\-1*1=-1[/tex]

Then, we simplify the entire expression.

[tex]\tt 7-3x-1=-3x+6[/tex]

[tex]\tt Step~3:[/tex]

Our equation now:

[tex]\tt 3x+1.5=-3x+6[/tex]

Let's add 3x to the right and 3x to the left to simplify the -3x on the right side of the equation.

[tex]\tt 3x(+3x)+1.5=-3x (3x)+6\\6x+1.5=6[/tex]

[tex]\tt Step~4:[/tex]

Let's do the same thing we did in Step 3 to 1.5. Subtract 1.5 on both sides of the equation.

[tex]\tt 6x+1.5(-1.5)=6(-1.5)\\6x=4.5[/tex]

[tex]\tt Step~5:[/tex]

Finally, we divide both sides by 6 to isolate x.

[tex]\tt \frac{6x}{6} =x\\\frac{4.5}{6}= 0.75~or~\frac{3}{4}[/tex]

[tex]\frac{y}{3} - 5 = 4\\\\\frac{y}{3} \cdot 3 - 5 \cdot 3 = 4 \cdot 3\\ y - 15 = 12\\y = 12 + 15\\y = 27[/tex]

Answer:

y = 27

Step-by-step explanation:

So we have to solve for y in the given equation.

[tex]\frac{y}{3}-5=4[/tex]

Add 5 to both sides.

[tex]\frac{y}{3}=9[/tex]

Multiply both sides of the equation by 3.

y = 27

So we have found that y = 27.
