-1 and 8

Step-by-step explanation:

-1 x 8 = -8

-1 + 7 = 7

now, if we look at the values as "x" races fast towards ∞, we can as you see above, use the values of 10, 1000, 100000000 and so on, as the value above oddly enough remains at 1, it could have been smaller but it's constantly 1 in this case, the value at the bottom is ever becoming a larger and larger denominator.

let's recall that the larger the denominator, the smaller the fraction, so the expression is ever going towards a tiny and tinier and really tinier fraction, a fraction that is ever approaching 0.

Bottom Up method

Explanation:

If we closely observe the Oksapmin method of counting, it is counting numbers by counting of body parts and the bottom up method is followed where normally a student will start from him thumb and call body part names as he counts the upper periphery of the body.

If a student has to solve simple addition, he would simply start from counting his fingers irrespective of which finger to start with. Hence instead of following principle he jumps to calculations

She had 23 nickles and 31 dimes

Step-by-step explanation:

The given is:

We need to find how many nickels and dimes she had

Assume that the number of nickels is x and the number of dimes is y

∵ Isabel had 54 coins

∵ The number of nickels is x

∵ The number of dimes is y

∴ x + y = 54 ⇒ (1)

∵ 1 nickle = 5 cents

∵ 1 dime = 10 cents

∵ The coins totaled $4.25

- Change the dollars to cents

∵ 1 dollar = 100 cents

∴ $4.25 = 4.25 × 100 = 425 cents

- Multiply the number of nickles by 5 and the number of dimes

  by 10, add the two products and equate the sum by 425

∴ 5x + 10y = 425 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -10 to eliminate y

∵ -10x - 10y = -540 ⇒ (3)

- Add equations (2) and (3)

∴ -5x = -155

- Divide both sides by -5

∴ x = 23

Substitute the value of x in equation (1) to find y

∵ 23 + y = 54

- Subtract 23 from both sides

∴ y = 31

She had 23 nickles and 31 dimes

The time required is 15.97 second.

Step-by-step explanation:

Consider the provided information.

A skywalk is 90 feet beyond the canyon's edge and is 4080 ft above the canyon floor.

First find the distance between skywalk and canyon floor by using Pythagorean theorem.

Distance between skywalk and canyon's edge =

Distance between skywalk and canyon's edge =

Substitute h = 4080.99 in the provided formula.

Hence, the time required is 15.97 second.
