SSS - Theorem 

All the sides to you in the problem are given to you and no angles. 
The sides also proportioned out to each other by 1/2. 
In other words, the triangle on the right is 1/2 smaller than the one on the left

Because all 3 sides are given for both triangles you can use the SSS theorem

Fred is making a bouquet of carnations and roses. The carnations cost $5.25 in all. The roses cost $1.68 each. How many roses di
olga nikolaevna [1]

Answer:

8 roses

Step-by-step explanation:

First start by subtracting $18.69 by $5.25 because you already know how much the carnations cost and how much the bouquet cost in all. When you subtract 18.69 by 5.25 you should get $13.44. If each rose cost $1.68 then divide 13.44 by 1.68 to get the amount of roses in the bouquet.

In triangle EFG, m of E = 30 degrees, m of F = 60 degrees, and m of G = 90 degrees. Which of the following statements about tria
Effectus [21]

Answer:

A. EG = √3 × FG

D. EG = √3/2 × EF

E. EF = 2 × FG

Step-by-step explanation:

∵ tan 60 = √3

∵ tan60 = EG/GF

∴ EG/GF = √3

∴ EG = √3 × GF ⇒ A

∵ m∠F = 60°

∵ sin60 = √3/2

∵ sin 60 = EG/EF

∴ √3/2 = EG/EF

∴ EG = √3/2 × EF ⇒ D

∵ cos60 = 1/2

∵ cos60 = GF/EF

∴ GF/EF = 1/2

∴ EF = 2 × GF ⇒ E

G(x) = x3 + 6x2 + 12x + 8
Sonbull [250]

The function’s value when x = −1 will be C. g(−1) = 1.

<h3>How to calculate the value of the function?</h3>

It should be noted that that a function is simply used to show the relationship that exists between the variables.

There's a 2-column table with 5 rows. The first column is labeled g of x with entries negative 3, negative 2, 0, 2, 3. The second column is labeled f of x with entries.

The. function is x³ + 6x² + 12x + 8.

= x³ + 6x² + 12x + 8.

= (-1)³ + 6(-1)² + 12(-1) + 8

= -1 + 6 - 12 + 8

= 1

Therefore, the correct option is C.

Sue travels by bus or walks when she visits the shops. The probability that she catches the bus to the shops is 0.4. The probabi
Ksenya-84 [330]

Answer:

Proved,

P(A∪B)=0.72

Step-by-step explanation:

Sue travels by bus or walks when she visits the shops.

Probability( catch the bus to the shop ), P(A) = 0.4

Probability( catch the bus from the shop ), P(B) = 0.7

Both A and B are independent events.

Therefore,

P(A∩B) = 0.4×0.7

           = 0.28

Probability Sue walks one way = 1 - P(A∩B)

                                                   = 1 - 0.28

                                                   = 0.72

Hence, the probability that Sue walks at one way is 0.72
