Angles A and B together create a 90° angle. ∠A = 4x −10 and ∠B = 2x − 20. Find the angle measures (what will

Answers

Answer:

see below

Step-by-step explanation:

A+ B = 90

4x-10 + 2x-10 = 90

Combine like terms

6x -20 = 90

Add 20 to each side

6x -20+20 = 90+20

6x = 110

Divide by 6

6x/6 = 110/6

x = 55/3

A = 4x-10  = 4(55/3)  -10

Aaron is 5 years younger than
Roy. Four years later, Roy will be
twice as old as Aaron. Find their
present ages

Answers

Answer:

Roy is 6 years old and Aaron is 1 year old.

Step-by-step explanation:

A is Aaron's age,

R is roy's age,

A = R - 5

R + 4 = 2(A+4)

We can distribute first,

R + 4 = 2A + 8

Subtract 4 from each side,

R = 2A + 4

Since A = R - 5, you can substitute in R - 5 for A in the equation,

R = 2(R-5) + 4

Distribute,

R = 2R - 10 + 4

Since - 10 + 4 = -6, we can do this,

R = 2R - 6

Subtract R from both sides,

0 = R - 6

Add 6 to both sides and you have part of your answer;

R = 6

Since A = R - 5,

A = 6 - 5

A = 1, so Aaron's age is 1.

Draw the graphs of the equations x – y = 1 and 2x + y = 8. Shade the area bounded by these two lines and y-axis. Also, determine this area.

Answers

Answer:

Using Geometry to answer the question would be the simplest:

Step-by-step explanation:

Remembering the formula for the area of a triangle which is [tex]A=\frac12bh[/tex]. One can then tackle the question by doing the following:

Step 1 Find the y-intercepts

The y-intercepts are found by substituting in [tex]x=0[/tex].

Which gives you this when you plug it into both equations:

[tex]-y=1\\y=-1\\y=8[/tex]

So the y-intercepts for the graphs are [tex](0,-1)\\[/tex], and [tex](0,8)[/tex] respectively.

Now one has to use elimination to solve the problems by adding up the equations we get:

[tex]x-y=1\\2x+y=8\\3x=9\\x=3[/tex]

Now to solve for the y component substitute:

[tex]2(3)+y=8\\y=2[/tex]

Therefore, the graphs intersect at the following:

[tex](3,2)[/tex]

Now we have our triangle which is accompanied by the graph.

now to solve it we must figure out how long the base is:

[tex]b=8-(-1)\\b=9[/tex]

The height must also be accounted for which is the following:

[tex]h=3[/tex]

Now the formula can be used:

[tex]A=\frac12bh=\frac12(9)(3)=\frac{27}2\ \text{units}^2[/tex]

Answer: 13.5 units²

Step-by-step explanation:

Geometry Solution:

The base is along the y-axis from -1 to 8 = 9 units

The height is the largest x-value = 3

[tex]Area=\dfrac{base\times height}{2}\quad =\dfrac{9\times 3}{2}\quad =\dfrac{27}{2}\quad =\large\boxed{13.5}[/tex]

Calculus Solution:

[tex]\int^3_0[(-2x+8)-(x-1)]dx\\\\\\=\int^3_0(-3x+9)dx\\\\\\=\bigg(\dfrac{-3x^2}{2}+9x\bigg)\bigg|^3_0\\\\\\=\bigg(\dfrac{-3(3)^2}{2}+9(3)\bigg)-\bigg(\dfrac{-3(0)^2}{2}+9(0)\bigg)\\\\\\=\dfrac{-27}{2}+27-0-0\\\\\\=\dfrac{27}{2}\quad =\large\boxed{13.5}[/tex]

Find the area of the the regular polygon.

Answers

Answer:

Area of Regular Polygon = ( About ) 332.6 units^2; Option C

Step-by-step explanation:

~ Let us first declare consecutive notes. If we were to draw an altitude in this triangle, it would be perpendicular to the base, by definition. At the same time this shape is a regular polygon, so all sides ( and angles ) are ≅. This would mean that, by Coincidence Theorem, the altitude divides the base into the two ≅ parts. ~

1. If that is so, the altitude would split this base into parts ⇒ ( 16√3 )/2 = 8√3.

2. This would mean that the altitude can be found through Pythagorean Theorem, provided that by definition it forms a 90 degree angle at the base. Let us say x ⇒ the length of the altitude, ( 8√3 )^2 + ( x )^2 = ( 16√3 )^2 ⇒ 192 + x^2 = 768 ⇒ x^2 = 576 ⇒ length of altitude - 24 units

3. With the base 16√3 units, and the the altitude/height 24 units, we can find the area of this regular polygon to be ⇒ 1/2 * base * height ⇒ 1/2 * 16√3 * 24 ⇒ 192√3 units^2

4. That being said that area would be 192 * 1.732050808...... ⇒

Area of Regular Polygon = ( About ) 332.6 units^2

When's the 3 digit number is rounded to the nearest hundred it round to 400.The digit in the ones place is the fourth odd number you count beginning with 1.The sum of the digits is 12.What is the number

Answers

Answer:

417

Step-by-step explanation:

count 1, 3, 5, (7) is the fourth one

it needs to be rounded to 400 so it is between 350 and 450

lets try in the 300s, 12 -(3 + 7) = 2. but 327 does not round to 400 so it does not work

lets try in the 400s, 12 - (4 + 7) = 1. put that one in the middle and you get 417 which fits the entire description

Answer:

Cannot be determined since the question is wrong.

Step-by-step explanation:

The fourth odd number is: 1, 3, 5, 7

h+t+o=12

h+t+7=12

Subtract 7 from both sides

h+t=5

If it rounds up to 400, h must be 3.

3+t=5

Subtract 3 from both sides

t=2

So our number is 327? It doesn't round up to 400 so the question is probably wrong. You probably got a typo in their like the numbers adding up to 12 or rounding to 300.

During a basketball game, Jeremy scored triple the number of points as Donovan. Kolby scored double the number of points as Donovan. So, if the three boys scored 36 points, how many points did Jeremy score? And how many points did Donovan score?

Answers

Answer: Jeremy score 18 points; Donovan score 6 points.

Step-by-step explanation:

Let Jeremy's points be a

Let Donovan's point be b

Let Kolby point be c

Jeremy scored triple the number of points as Donovan. This is:

a = 3b

Kolby scored double the number of points as Donovan. This will be:

c = 2b

The the three boys scored 36 points. This will be:

a + b + c = 36

Since a = 3b and c = 2b

Plug the equations for a and c into the equation. This will be:

a + b + c = 36

3b + b + 2b = 36

6b = 36

b = 36/6

b = 6

Donovan has 6 points

Jeremy will have:

a = 3b

a = 3 × 6

a = 18

Jeremy has 18 points.

Kolby will have:

c = 2b

c = 2 × 6

c = 12

Kolby will have 12 points.

Answers

Answer:

D

Step-by-step explanation:

When we talk of the range, that means the difference between the highest and the lowest figure in the data set

The mean refers to the sum of the values in the data set divided by the count of the value in the data set.

let’s take a look at data set option A;

mean = [4(14) + 2(7)]/6 = (56 + 14)/6 = 70/6 which is definitely not 14 which makes the option wrong

Let’s take a look at option C

mean = {13(3) + 15)3)}/6 = (39 + 45)/6 = 84/6 = 14

While the range is 15-13 = 2 which does not make it right too

Now, a look at option D

mean = (13 + 12 + 15 + 15 + 11 + 18)/6 = 84/6 = 14

range = 18-11 = 7 (highway number in the set minus lowest number)

This makes option D our answer

Answers

Answer:

A opção correta é;

c) 12,8 m²

Step-by-step explanation:

A área de um trapézio = 1/2 × (distância perpendicular entre os lados paralelos) × (soma dos comprimentos dos lados paralelos)

No diagrama da pergunta, os comprimentos dos lados paralelos são;

3,8 me 2,6 m

A distância perpendicular entre os lados paralelos = 4 m

∴ área do trapézio = 1/2 (3,8 + 2,6) × 4 = 12,8 m²

Portanto, a área da sala = 12,8 m².

Out of these four card choices, for the first pick there are two even cards and four cards in total. This means that on the first pick there is a 2/4=1/2 chance that you pick an even card. On the second pick, if you do not replace the card, then there is 1 even card remaining, and 3 cards in total, leaving a probability of 1/3.

Answers

Answer:

The difference between the average speed is 12 kilometers per hour, where Serah's train has the greatest speed.

Step-by-step explanation:

Givens

Javier's train travels 130 km in 75 minutes.Serah's train travels 377 km from 9:35 to 12:50.

The average speed is defined as

[tex]s=\frac{d}{t}[/tex]

To finde Javier's speed, we need to transform 75 minutes into hours, we know that 1 hour is equivalent to 60 minutes.

[tex]h=75min \times \frac{1hr}{60min} =1.25 \ hr[/tex]

Now, we find the average speed

[tex]s_{Javier}=\frac{130km}{1.25hr}=104 \ km/hr[/tex]

Therefore, Javier's train travels 104 kilometers per hour.

On the other hand, Serah's traing travels from 9:35 to 12:50, which is equivalent to 3 hours and 15 minutes, but 15 minutes is equivalent to 0.25, so the total time is 3.25 hours, so the average speed is

[tex]s_{Serah}=\frac{377km}{3.25hr}= 116 \ km/hr[/tex]

So, the difference would be

[tex]116-104=12 \ km/hr[/tex]

Therefore, the difference between the average speed is 12 kilometers per hour, where Serah's train has the greatest speed.

Answer:

12 km/h

What happens when the amplitude of the grade of the sine function increases?

(Don’t pay attention to the answer chosen)

Answers

Answer:

The increase of amplitude would increase distance between the maximum and minimun point of the wave.

Step-by-step explanation:

We can defined the amplitude of a wave as the height of it, because it's the distance from the maxium point to the minimum point. In other words, it's the longest vertical displacement along the wave.

Additionally, amplitude represents power, when we apply waves to real phenomenons like the sound. So, greater grade of amplitude would represent louder sounds.

Therefore, the increase of amplitude would increase distance between the maximum and minimun point of the wave.
