Slav-nsk [51]

Answer:

Option $152.19

Step-by-step explanation:

Data provided in the question:

Previous balance = $152.35

Finance charge = $1.78

New purchases of $45.23 and $15.67

Payment = $50.00

Credit = $12.84

Now,

New Balance

= [Previous balance + Finance charge + New purchases ] - [ Payments + Credits ]

= [ $152.35 + $1.78 + ($45.23 + $15.67) ] - [$50.00 + $12.84 ]

= $215.03 - $62.84

= $152.19

Hence,

Option $152.19

ivolga24 [154]
1.08 m. is the answer because you would use the pythagorean theorem to solve it.  
2.8^2+b^2=3^2
7.84+b^2=9
b^2=9-7.84
square root of b^2=square root of 1.16
b=1.08

Javier simplified the expression below. Find and describe the three mistakes he made.
Irina18 [472]

Which of the following did you include in your response?

Javier did not raise the coefficients to the third power

When Javier raised (x^1)^3 to the third power, he wrote that x^4, but it equals x^3.

In the last step, Javier divided the exponents. He should have used the quotient of powers property and subtracted them.

1,250 an 15% sale an 6.5 sales tax
eimsori [14]
Given:
price = 1,250
sales discount = 15%
sales tax = 6.5%

The problem is unclear whether the price is the original price or the discounted price. I am assuming that the price is the original price.

Original price times sales discount rate is the value of sales discount
1,250 x 15% = 187.50

Original price less the value of sales discount is the discounted price.
1,250 - 187.50 = 1,062.50

Discounted price times sales tax rate is the value of the sales tax
1,062.50 x 6.5% = 69.06 

Discounted price plus sales tax is the total cost of the purchase
1,062.50 + 69.06 = 1,131.56

The graph below is used by company 2 to show the average monthly electric cost based on the electricity provider.
defon
Given the bar graph above, the difference <span>in monthly electric cost appear to be great because of the choice of scale.

In scaling, the narrower the intervals of the axis, the larger the graph and the more highlighted the relative difference between the components of the graph.

Conversely, the wider the </span><span>the intervals of the axis, the smaller the graph and the less highlighted the relative difference between the components of the graph.

Therefore, to make </span><span>the difference in monthly electric cost appear not to be as great</span>, we widden the intervals on the y-axis.
i.e. '<span>The interval on the y-axis could be changed to count by 20s.'</span>
