Answer:

4) 50,000

5) 900,000

Step-by-step explanation:

In Front end rounding what we do is we focus on first two digit of the number if the second digit number is greater than or equal to 5 we add the first digit by 1.

4) 50,987

here we can clearly see that the first two digit is 50 and second digit is not equal to 5 then rounding will be equal to 50,000.

5) 851,004

here we can clearly see that the first two digit is 85 and second digit is equal to 5 then we will round it  8+1=9

hence rounded number will be 900,000

Elena-2011 [213]

The amount of drinks is a linear function of the number of drinks. The maximum amount that can be purchased is 100 soft drinks.

Let

y \to amount of drinks

x \to number of drinks

For drinks not more than 50

y = 10 + 0.8x

For drinks more than 50.

y = 15 + 0.7x

For a purchase of $85, it means that:

y = 85

So, we solve for x in both equations.

y = 10 + 0.8x

85 = 10 + 0.8x

Collect like terms

0.8x = 85-10

0.8x = 75

Divide through by 0.8

x = 93.75

x = 94 --- approximated

y = 15 + 0.7x

85 =15 + 0.7x

Collect like terms

0.7x = 85 - 15

0.7x = 70

Divide by 0.7

x = 100

By comparing both values:

x = 100

x = 94

100 > 94

Hence, the maximum amount that can be purchased is 100

Scilla [17]

(A) The formula for nth bounce is a_n = 20 (7/9)^{n}.

(B) 4.43 feet is the maximum height of the ball on the 6th bounce.

<h3>What is an algebraic expression?</h3>

An algebraic expression is consists of variables, numbers with various mathematical operations,

Given that,

The height from where the ball is dropped = 20 feet.

Also, the ball bounces and returns to 7/9 to its original height.

(A)

The representation of the maximum height of the ball on the nth bounce can be given as

a_n = 20 (7/9)^{n}

(B)

The maximum height of the ball on the 6th bounce = 20 (7/9)⁶ =  4.43 feet
