Answers

Answer 1

[tex]3(x-8)[/tex][tex]3(x+5)[/tex]

Explanation

Step 1

7)

[tex]\begin{gathered} 3x-24 \\ \end{gathered}[/tex]

get the factors of each number

[tex]\begin{gathered} 3x=3\cdot x \\ 24=3\cdot2\cdot2\cdot2\cdot=3\cdot8 \end{gathered}[/tex]

so, the GCF is 3

[tex]\begin{gathered} 3x-24=3(\frac{3x}{3}-\frac{24}{3}) \\ 3x-24=3(x-8) \end{gathered}[/tex]

Step 2

8)

[tex]3x+15[/tex]

get the factors of each number

[tex]\begin{gathered} 3x=3\cdot x \\ 15=3\cdot5 \end{gathered}[/tex]

so, the GCF is 3

[tex]3x+15\rightarrow3(\frac{3x}{3}+\frac{15}{3})\rightarrow3(x+5)[/tex]

Answers

A regular 9 sided building is 814 ft along one side what is the distance from a Vertex to the center of the building ​

we know that

A regular 9 sided polygon, can be divided into 9 isosceles triangle

The equal distances of the isosceles triangle is equal to the radius or the distance from a Vertex to the center of the building ​

the base of the isosceles triangle is given and is equal to 814 ft

The measure of the interior angle of the vertex is equal to

360/9=40 degrees

that means

we have

Applying the law of sines

814/sin(40)=r/sin(70)

solve for r

r=(814/sin(40))*sin(70)

r=1,190 ft

therefore

the distance is 1,190 ft

Explanation

As we know domain of a function is all the values of x that makes the function defined.

here in the graph , the function is defines for x values 0 to 5

since , the point 0 and 5 is in open interval , so , the graph does not include the points 0 and 5

hence , the domain is (0 , 5)

Answers

Solution:

Given the table below:

From the table,

[tex]\begin{gathered} Number\text{ of seventh graders = 27} \\ Number\text{ of eighth graders = 23} \end{gathered}[/tex]

Since there are more seventh-graders than eighth-graders, we can evaluate the number of more seventh-graders by subtracting the number of eighth-graders from the number of seventh-graders.

Thus, we have

In a class of 30 students, 19 have a cat and 12 have a dog. There are 6 students who do not have a cat or a dog. What is the probability that a student has a cat given that they have a dog?

Answers

We are asked to find the probability to find a student that has a cat when we know he/she has a dog. Then, we need to know how many students have a dog, and how many have a dog and a cat.

We already know that 12 students have a dog. However we do not know how many students have a cat and a dog.

Let's calculate that.

We know we have 30 students.

We know 6 do not have dogs nor cats.

[tex]19\text{ + 12 +6 = 37}[/tex]

The sum of students having dogs, the students having cats and the students having none is 37, but we know that there are only 30 students. Then, we can say that 7 students have both a dog and a cat. That is just the information we needed.

Then, we can calculate the probability that a student has a cat given that they have a dog as follows:

Let's say P is that probability:

[tex]P=\frac{\text{Number of students having both}}{\text{Number of students having a dog}}=\frac{7}{12}[/tex][tex]P=\frac{7}{12}=0.5833=58.33\text{ \%}[/tex]

Using cosine rule to solve for the length of the tunnel:

c=length of side c

a=length of side a

b=length of side b

A=angle opposite c

[tex]\begin{gathered} a^2=116^2+247^2-2(116)(247)cos78^0 \\ a^=\sqrt{116^2+247^2-57304cos78} \\ a=250.1016 \end{gathered}[/tex]

We are told that jose is 35 years old and makes 40.000 per year. Also, we are told that they can get by 75% of his income. So, in the table, we look for the age column for 35 years and in the gross earnings we look for the 40000 row.

Inside the 35 years column, we take a look at the inner column that says 75%. Crossing all this information, we get that the table shows a multiplier of 8.0

From the statement, we know that:

• P(A and B) = 0.2.

Because A and B are independent events, the probability of A and B is the product of the individual probabilities:

[tex]P(A\text{ and }B)=P(A)*P(B)\Rightarrow P(B)=\frac{P(A\text{ and }B)}{P(A)}.[/tex]

Test ContentQuestion 110 PointsA box is 36 inches long, 18 inches wide, and 6 inches deep. How many cubic feet are in the box?A 5 cubic feetB4.5 cubic feet© 3 cubic feetD2.25 cubic feet

Answers

The box is 2.25 cubic feet (option D)

Explanation:

length of the box = 36 inches

width = 18 inches

depth = height = 6 inches

To get the volume of the box in cubic feet, we need to first convert the dimensions from iches to feet to make it easy to solve.

conversion from iches to ft:

12 inches = 1 ft

36 inches = 36/12

= 3 ft

18 inches = 18/12

width = 18 inches = 3/2 ft

6 inches = 6/12

height = 6 inches = 1/2 ft

The box is a rectangular prism

Volume of rectangular prism = length × width × height

[tex]\begin{gathered} \text{Volume of the rectangular prism = 3 ft }\times\text{ }\frac{3}{2}\text{ ft }\times\text{ }\frac{1}{2}\text{ ft} \\ \text{Volume of the rectangular prism = 9/4 ft}^3\text{ = }2.25ft^3 \\ \\ \\ Volume\text{ of the box = 2.25 cubic f}eet\text{ (option D)} \end{gathered}[/tex]

tan (θ) cot (θ)=1Trig: use trigonometric identities to transform the left side of the equation into the right side

Answers

1) Let's prove this identity

Since tan (θ) = sin(θ)/cos((θ)

And cot((θ) = cos ((θ)/sin((θ)

2) Let's plug it into:

[tex]\begin{gathered} \tan \text{ (}\theta)\cot \text{ (}\theta)\text{ =1} \\ \frac{\sin (\theta)}{\cos (\theta)}\cdot\frac{\cos (\theta)}{\sin (\theta)}=1 \\ 1=1 \end{gathered}[/tex]

Simplifying (dividing) sin(θ) on the numerator, with sin (θ) on the denominator and similarly cos (θ) with cos(θ) we'll get to 1 over 1 time 1 over 1 = 1

Robert is paid $12.00 per hour to chop firewood he chops 40% of the pile of firewood in 3/4 of an hour at this rate how much will Robert be paid to chop the entire pile of firewood?

Answers

Robert chops 40% of the pile of firewood in 3/4 of an hour.

Then, we would chop 80% of the pile of firewood in 2*(3/4)=3/2 hours.

where 3/2 = 1.5 hours

Also, he would chop the missing 20% in (3/4)/2=3/8.

The full work is for 3/8+3/2 =15/8 hours

Now, if one hour is paid $12.00, we can use the rule of three to know how much is paid for 15/8 hours:

1h-----------$12.00

15/8 h -------- $x

where x=(12.00*5/8)/1

x=22.50

Hence, Robert will be paid $22.50 to chop the entire pile of firewood.

UW = 10

Explanation

From the image attached, we can see that

UV + VW = UW

But

UV = 2x + 3

VW = 7

UW = x + 10

UV + VW = UW

(2x + 3) + 7 = x + 10

2x + 3 + 7 = x + 10

2x + 10 = x + 10

2x - x = 10 - 10

x = 0

UW = UV + VW

UW = 2x + 3 + 7

UW = 2 (0) + 10

UW = 0 + 10

UW = 10

We can eliminate some of these choices , knowing that if we dilate a triangle they are the same shape but not necessarily the same size. Thus , they are not congruent. Therefore, the last two choices are false since it denotes congruency.

It is also stated from the problem that the triangle is rotated by 180 degrees therefore the congurent pair of angle can be found on the opposite side in the figure. Therefore , we can eliminate the first choice since it states that the congruency among angles are at the same side.

Thus, CHOICE 2 is true.
