No, because SSA isn't a triangle congruence theorem. Therefore, option A is the correct answer.

Given that, the figure shown models a roof truss. Based on the markings, is there enough information to prove that ΔCED≅ΔCGD.

Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal.

In the ΔCED and ΔCGD

DE=DG (Given)

∠CED=∠CGD (Given)

CD=CD (Common)

SSA congruence is not valid.

No, because SSA isn't a triangle congruence theorem. Therefore, option A is the correct answer.

Step-by-step explanation:

tan-1 7/12 = 30.26

Answer:

w = -7z/2

Step-by-step explanation:

We need to solve for w in terms of z.

The equation given is:

5w + 9z = 2z + 3w

Collect like terms:

5w - 3w = 2z - 9z

2w = -7z

w = -7z/2

Answer:

option A (-7/2z)

Answer:

6 : 5

Step-by-step explanation:

Each set takes Krutika 72 minutes.

Each set takes Natasha 1 hour.

Let us convert that to minutes:

1 hour = 60 minutes

Therefore, expressing the times it takes Krutika and Natasha as a ratio:

72 : 60

Divide by 6

12 : 10

Divide by 2

6 : 5

The ratio is 6 : 5

These are complementary angles.

If two angles are complementary, then

the sum of their measures is 90°.

Since we know that one of the angles measures 35°, we can find the measure of the other by taking 90 minus the measure of the original angle which in this case is 90 - 35.

So we have 90° - 35° which is 55°

So the measure of the other angle is 55°

Answer:

9 is the greater x and 2 is the lesser x

Step-by-step explanation:

I really don't know how to explain without simply writing it out for you, which I really can't do. But there's the answer lol

Answer:

x = 2, x = 9

Step-by-step explanation:

Given

x² - 11x + 18 = 0

Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)

The factors are - 9 and - 2 , since

- 9 × - 2 = + 18 and - 9 - 2 = - 11 , thus

(x - 9)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2 ← lesser value

x - 9 = 0 ⇒ x = 9 ← greater value

Answer:

f = 6, g = 8

Step-by-step explanation:

The area of Δ ADE = 60 - 48 = 12 cm²

Thus

[tex]\frac{1}{2}[/tex] AD × 4 = 12, that is

2AD = 12 ( divide both sides by 2 )

AD = 6 = f

The area of ABCD = 48 cm² , thus

fg = 48 , that is

6g = 48 ( divide both sides by 6 )

g = 8

Thus f = 6 and  g = 8

Answer:

h(11) = -20 + 11 * 11 = 101

Answer:

h(11)=101

Step-by-step explanation:

This question asks us to find h(11).

Essentially, we need to find h(t) or y, when t, or x, is equal to 11.

h(t)=-20+11t

Therefore, we can substitute 11 in for every t.

h(11)= -20+11(11)

Solve according to PEMDAS( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

Multiply 11 and 11 first.

h(11)= -20 +121

Add 121 and -20

h(11)=101

Step-by-step explanation:

A) 1. subtract -x on both sides              2. to get 3x-1/2=7  

3. Add 1/2 on both sides                    4. to get 3x=7.5    

5. divide 3 on both sides                   6. To get... x=2.5

B)1. Same process.                               2. x+2=13/3        

3. x=13/3-2                                         4. x= 2.33(repeating)

C) 1. same process.                           2. 2x-x/3=3+7/4

Answer:

No, if 4 teachers chose 24 students from 1 class to go then the teachers will not be 25% of the passengers.

Step-by-step explanation:

Given: If 4 teachers chose 24 students from 1 class to go then the teachers will be 25% of the passengers.

To find: if the given statement is correct or not

Solution:

Total number of teachers = 4

Total number of students = 24

Total number of passengers = Total number of teachers + Total number of students = 4 + 24 = 28

Here,

25% of Total number of passengers = [tex]\frac{25}{100}(28)=7\neq 4[/tex]

So, if 4 teachers chose 24 students from 1 class to go then the teachers will not be 25% of the passengers.

Answer:

414 9/16 m³

[tex]414\frac{9}{16}m^{3}[/tex]

Step-by-step explanation:

The volume of a Rectangular prism is calculated as Length × Width × Height

From the attached diagram,we can see that

The length = 8 3/8 m

The width = 6 m

The height =8 1/4 m

Converting the mixed fraction to improper fraction in other to simplify it better

The length = 67/8 m

The height = 33/4 m

The volume of the rectangular prism =

67/8 m × 6m × 33/4m

= (13266/32)m³

= 6633/16 m³

= 414 9/16 m³

= [tex]414\frac{9}{16}m^{3}[/tex]

Answer:

1/2 litros es igual a la capacidad que le pidió su mamá.

Step-by-step explanation:

Para encontrar la respuesta debes escribir 0.5 como fracción. Para hacerlo, el numerador es el número original sin el punto decimal y para definir el denominador debes determinar cuántos digitos decimales tienes. En este caso, el número tiene un dígito decimal, por lo cual el denominador es 10. De acuerdo a esto:

0.5 se escribiría como [tex]\frac{5}{10}[/tex] y esta fracción se puede simplificar porque los dos números son divisibles entre 5:

5/5= 1

10/5= 2

Por esto, 0.5= [tex]\frac{1}{2}[/tex]

Esto significa que 1/2 litros es igual a la capacidad que le pidió su mama.

Answer:

-21. -19.-17

Step-by-step explanation:

Let x be the smallest

x+2 next smallest

x+4 be the largest

4*(x) = 18+6(x+4)

Distribute

4x = 18+6x+24

Combine like terms

4x = 42+6x

Subtract 6x from each side

-2x = 42

Divide by -2

-2x/-2 = 42/-2

x = -21

x+2 = -19

x+4 = -17

Answer:

- 21, - 19, - 17

Step-by-step explanation:

Let y be the smallest no.

& y + 2 next smallest no.

& y + 4 be the largest no.

= 4 * (y) = 18 + 6 * (y + 4)

4y = 18 + 6y + 24

4y - 6y = 42

- 2y = 42

= - 21

The other 2 numbers are:

y + 2

= - 19

y + 4

= - 17

Answer:

The 99th tower contains 9900 blocks.

Step-by-step explanation:

From the question given, we were told that the nth tower is formed by stacking n blocks on top of an n times n square of blocks. This implies that the number of blocks in n tower will be:

n + n²

Now let us use the diagram to validate the idea.

Tower 1:

n = 1

Number of blocks = 1 + 1² = 2

Tower 2:

Number of blocks = 2 + 2² = 6

Tower 3:

Number of blocks = 3 + 3² = 12

Using same idea, we can obtain the number of blocks in the 99th tower as follow:

Tower 99:

n = 99

Number of blocks = 99 + 99² = 9900

Therefore, the 99th tower contains 9900 blocks.
