Answer 1

Answer:

[tex]\displaystyle S_{27}=675[/tex]

Step-by-step explanation:

The sum of N consecutive natural numbers is given by:

[tex]\displaystyle S_N=\frac{N}{2}(F+L)[/tex]

We need to find the sum of the natural numbers between 12 to 38.

To calculate the required sum we have F=12, L=38, but we don't have the value of N.

From 12 to 38 there are 38 - 12 + 1 = 27 natural consecutive numbers, thus N=27.

Substituting in the formula:

[tex]\displaystyle S_{27}=\frac{27}{2}(12+38)[/tex]

[tex]\displaystyle S_{27}=\frac{27}{2}(50)[/tex]

[tex]\displaystyle S_{27}=27*25[/tex]

[tex]\mathbf{\displaystyle S_{27}=675}[/tex]

The values of the Ferris wheel.

The Ferris wheel is a ride that is fired by the upright rotating wheel and is able of carrying multiple passengers. The table shows us the value of the height of a car of the Ferris wheel and as it travels in a circular motion. The time and height of the second and meters are given.

Thus the answer is if the car is loaded at 0 s, then people are at the lowest part.

The wheel data shows that in 2 seconds the height of the wheel is about 26 meters and in 16 seconds the height of the wheel is about 6 meters. Thus the car is located at 0s and people are at the lowest height of the wheel.Hence the option C is correct.

Answer:

  A)  29/40

Step-by-step explanation:

The formula for this is ...

  P(A or B) = P(A) + P(B) - P(A and B)

Filling in the given values, you have ...

  P(A or B) = 9/20 +1/2 - 9/40

  P(A or B) = 18/40 +20/40 -9/40 = (18+20-9)/40

  P(A or B) = 29/40 . . . . matches choice A

Tony bought 255 1-inch nails and 5 boxes of 2-inch nails. Each box of 2-inch nails had equal amounts of nails in them. He bought a total of 620 nails. Find the number of nails in each box of 2-inch nails.

Answers

Answer:

73 nails

Step-by-step explanation:

Number of 1 inch = 255

Boxes of 2 - inch = 5

Each box of 2 _inch has equal amount of nails

Total number of nails = 620

Number of nails in each box of 2_inch nails:

Let Number of nails in each box = b

Number of 1_inch + 5 * number of 2_inch = 620

255 + 5b = 620

5b = 620 - 255

5b = 365

5b / 5 = 365 / 5

b = 73

Hence, there are 73 nails in each box of 2_inch nails
