Find three consecutive even numbers whose sum is 1674.

Norma-Jean [14]

Answer:

556, 558, and 560

Step-by-step explanation:

1674/3 = 558 (An even number, yay)

So 558 + 558 + 558 = 1674

Subtract two from the first one and add two to the last (still equal)

556 + 558 + 560

adding them equals 1674 so the answer is

556, 558, and 560

An 8.0 kg block is moving at 3.2 m/s. A net force of 10 N is constantly applied on the block in the direction of its movement, u

Softa [21]

Answer:

5.02 m/s

Step-by-step explanation:

We are given that

Mass of block,m=8 kg

Initial velocity,u=3.2 m/s

Net force ,F=10 N

Distance,s=6 m

We have to find the approximate final velocity of the block.

We know that $a=\frac{F}{m}$

Using the formula

$a=\frac{10}{8}=\frac{5}{4} m/s^2$

We know that

$v=\sqrt{u^2+2as}$

Using the formula

$v=\sqrt{(3.2)^2+2\times \frac{5}{4}\times 6}$

$v=5.02 m/s$

Sara paid $11.88 total for apples, after a 3 dollar coupon, and $7.58 for berries with a $20 bill. How much change did Sara rece

Nataliya [291]

After the discount, Sara received a change of $3.54.

Define discount.

The discount is determined by dividing the purchase price by the item's par value. Discount is the type of original price reduction or a new lower price for a product. In other words, a discount is a sum of money or a portion of the regular selling price of anything.

Given that a discount is the price reduction of goods or services that store owners give at the advertised price, it can be computed using the formula Discount = List Price - Selling Price.

Solution Explained:

Given,
Price of apples = $11.88, price of berries = $7.58

The discount on the coupon is $3 and she paid with a $20 bill

So, total cost = 11.88 + 7.58 = 19.46

Applying discount on the cost = 19.46 - 3 = 16.46

The total change Sara gets is = 20 - 16.46 = $3.54

Therefore, Sara receives a change of $3.54
