Answer:

C. 5/18

Step-by-step explanation:

A quadrilateral is any shape with 4 sides, therefore a rectangle is a circle while the other ones are not.  Since there are 5 rectangle cards, the answer will be 5 over the number of total cars

8 triangle cards + 5 rectangle cards + 5 circle cards = 18 total cards

5 rectangle cards out of 18 total cards

It takes you 47 seconds to walk from the first​ (ground) floor of a building to the third floor.
Musya8 [376]

Answer: 117.5 seconds

Step-by-step explanation:

Given : It takes you 47 seconds to walk from the first​ (ground) floor of a building to the third floor.

Since from first floor to third , a person need to pass two levels of staircase.

We assume that the person walk at the same​ pace and the height of all floors are same.

The time taken to pass each level = (Time taken to pass 2 levels) ÷ 2

= (47 seconds)  ÷ (2) = 23.5 seconds

Also, the from first floor to sixth floor , a person need to pass 5 levels of staircase.

Then, the time taken to pass each level = 5 x (Time taken to pass one level)

= 5 x 23.5 =117.5 seconds

Hence, it will take 117.5 seconds to walk from the first floor to the sixth floor.

Determine whether the equation is always sometimes or never true 2(5x+4)=10x+6
Usimov [2.4K]
This equation is NEVER true. Let's solve the equations algebraically by applying the Distributive Property of Multiplication and transposing the terms across the equality sign. The solution is as follows:

<span>2(5x+4)=10x+6
10x + 8 = 10x + 6
10x - 10x = 6 - 8
0 = -2

Therefore, it is not true.</span>

Please help me with this question!!
Bess [88]

Answer:

x=16 * cos(46)

Step-by-step explanation:

Well, first let's look at our trig identities. We can set up a cosine function using the given angle:

cos (46^{o} ) = \frac{x}{16} (adjacent/hypotenuse)

Then, multiplying both sides by 16 gives us:

x=16 * cos(46)

Hope this helps!
