Answer:

8 units

Step-by-step explanation:

Using the perpendicular bisector theorem, if we know that TQ is 8 units, then RT must be 8 units as well.

Answer:

8

Step-by-step explanation:

Step 1: Find the length of segment TS (I will call this as y)

Method: Pythagoras

10² = y² + 8²

 = 100-64 = y²

y = square root of 36

y = 6

Step 2: Use the method of Pythagoras to find RT = (x)

10² = x² + 6²

x² = 100 - 36

x = 64 square root

x = 8

ANSWER

It is similar to triangle LMN and has coordinates L′(12, −16), M′(8, −8), and N′(−24, 4)

EXPLANATION

The given triangle LMN with vertices L(6, −8), M(4, −4), and N(−12, 2).

If this triangle is dilated by a scale factor of 2 to obtain triangle L′M′N, then we use the rule:

[tex](x,y)\to (2x,2y)[/tex]

can be used to obtain the coordinates of

L′M′N.

[tex]L(6,-8)\to(2 \times 6,2 \times - 8)=L'(12,-16)[/tex]

[tex]M(4,-4)\to(2 \times 4,2 \times - 4)=M'(8,-8)[/tex]

[tex]N(-12,2)\to(2 \times -12,2 \times 2)=N'(-24,4)[/tex]

The cot choice is:

It is similar to triangle LMN and has coordinates L′(12, −16), M′(8, −8), and N′(−24, 4)

Answer:

A

Step-by-step explanation:

Its the one that mostly makes sense

Answer:

See the graphic I made

Area of Section A = 4 *1 = 4 square centimeters

Section B = 4 * (3 + 4) = 28 sq cm

Section C = 3 * (2 + 3 + 4) = 27 sq cm

Total Area = 4 + 28 + 27 = 59 square centimeters

Step-by-step explanation:

To find the area of an octagon, you can use the formula 2 * (1 + √2) * s², where s is the length of one of the sides. If the area is given, you can solve for s and then use the formula to calculate the area.

The area of an octagon can be calculated using the formula:

Area = 2 * (1 + √2) * s²,

where s is the length of one of the sides of the octagon.

In this case, since the area is given as 0.4 m², we can solve for s.

0.4 = 2 * (1 + √2) * s²

Dividing both sides by 2 * (1 + √2) gives:

s² ≈ 0.2

Taking the square root of both sides, the length of one side is approximately 0.45 m.

To find the area, use the formula:

Area = 2 * (1 + √2) * (0.45)² ≈ 0.4 m²

Answer:

[tex]\frac{circumference\ }{diameter}=\pi[/tex]

Step-by-step explanation:

Given that radius of the circle = 10

Using π, we need to find about which equation expresses the ratio of the circumference of the circle to the circle's diameter.

diameter of the circle = 2(radius) = 2(10)=20

circumference of the circle = 2 π r = 2 π (10)  = 20 π

then ratio of the circumference of the circle to the circle's diameter is given by: [tex]\frac{circumference\ }{diameter}=\frac{20\pi}{20}=\pi[/tex].

Hence required equation is [tex]\frac{circumference\ }{diameter}=\pi[/tex]

The number of students attending the camp that summer is 380 students

Step-by-step explanation:

There are four counselors for every fifty seven students

There are three teachers for every five counselors

Ms. Rifkin asked all 16 teachers present at the camp to attend a

teachers meeting

To solve this question we will use the ratio

The given is:

1. 4 counselors for every 57 students

2. 3 teachers for every 5 counselors

3. There are 16 teachers

At first let us find the 16 teachers are for how many counselors

∵ 3 teachers : 5 counselors

∵ 16 teachers : x counselors

∴ [tex]\frac{3}{5}=\frac{16}{x}[/tex]

By using cross multiplication

∴ 3x = 16 × 5

∴ 3x = 80

Divide both side by 3

∴ x = [tex]\frac{80}{3}[/tex]

Then let us find the [tex]\frac{80}{3}[/tex] counselors are for how many students

∵ 4 counselors : 57 students

∵ [tex]\frac{80}{3}[/tex] counselors : y students

∴ [tex]\frac{4}{57}=\frac{80/3}{y}[/tex]

By using cross multiplication

∴ 4y = 57 × [tex]\frac{80}{3}[/tex]

∴ 4y = 1520

Divide both sides by 4

∴ y = 380 students

Answer:

I think that the answer is D. CB ║DE

To find the answer, all we need to is to calculate all the missing one.

So: ∠CBD = 180° - 60° - 40° = 80°

     ∠BDE = 180° - 60° - 40° = 80°

     ∠DEF = 180° - 60° - 45° = 75°

Since we have ∠CBD ≅ ∠BDE ( = 80°) and they are alternate interior angles, we can conlcude that CB ║ DE.

[tex]\large\boxed{C.\ a=\dfrac{400}{21},\ b=\dfrac{580}{21}}[/tex]

Step-by-step explanation:

(LOOK AT THE PICTURE)

ΔABC, ΔDBA and ΔDAC are similar (AAA). Therefore the corresponding sides are in proportion:

[tex]\dfrac{AB}{AD}=\dfrac{AC}{DC}[/tex]

We have AB = b, AD = 20, AC = 29 and DC = 21. Substitute:

[tex]\dfrac{b}{20}=\dfrac{29}{21}[/tex]             cross multiply

[tex]21b=(20)(29)[/tex]

[tex]21b=580[/tex]           divide both sides by 21

[tex]b=\dfrac{580}{21}[/tex]

and in proportion:

[tex]\dfrac{BD}{AD}=\dfrac{AD}{DC}[/tex]

We have BD = a, AD = 20 and DC = 21. Substitute:

[tex]\dfrac{a}{20}=\dfrac{20}{21}[/tex]           cross multiply

[tex]21a=(20)(20)[/tex]

[tex]21a=400[/tex]   divide both sides by 21

Answer: 12

Step-by-step explanation:

You can use what is called geometric mean to solve this.

The hypotenuse of this triangle is split into two sections. One section corresponds to/equal to the altitude which is our "X", which corresponds to/equal to the second section.

You find "X" by using geometric mean and the proportion:

16/X=X/9

Then cross multiply to get 16 x 9= 144

then 144=x²

Solve for X.

Step-by-step explanation:

x² + 3 x + 40 = 0

Answer:

The answers for x^2+3x−40=0 are -8 and 5.

Step-by-step explanation:

For this problem, we are able to factor. Since 8 and 5 are both factors of 40, and since 8-5=3, we will use 8 and 5 in our binomial equation:

(x+8)(x−5)=40.

Just to prove that this is correct, let's multiply the two together: x^2−5x+8x−40=x^2+3x−40.

From here, we can use the zero product property to get our answers: x+8=0,x−5=0.

Subtract 8 from the first equation and subtract 5 from the second equation to get our answers, -8 and 5.

Answer:

the first question is B

and I am very sorry i don't know the second question

Answer:

C, B

Step-by-step explanation:

The interior angle of a regular polygon is:

θ = (n - 2) × 180° / n

So a pentagon with 5 sides has an interior angle of:

θ = (5 - 2) × 180° / 5

θ = 108°

If we draw a line from the bottom left corner to the center, we get a right triangle.  Using tangent, we can say:

tan (108°/2) = a / (7.6/2)

tan (54°) = a / 3.8

a = 3.8 tan (54°)

a = 5.2

Answer C

If the interior angle is 144, then the number of sides is:

144 = (n - 2) × 180 / n

144n = 180n - 360

360 = 36n

n = 10
