Answers

Answer: Choice C) $1,444.50

========================================================

There are two methods to get the answer.

The slightly longer method is to take 7% of the original price to get

7% of 1350 = (7/100)*1350 = 0.07*1350 = 94.50

The sales tax is $94.50

Add this onto the original price to get 1,350+94.50 = 1,444.50

----------------------------

A shortcut is to multiply the original price by 1.07

The multiplier 1.07 represents a 7% increase since

1 = 100%0.07 = 7%1.07 = 1 + 0.7 = 100% + 7%

So we will have 1.07*1350 = 1,444.50

Answer:

$172.5

Step-by-step explanation:

Store A is defintley better because 6% of sales tax is $72 and $1200 + $71 = $1272 while store B: 7% of $1350 is $94.5 and $1350 + $94.5 = $1444.5. To find out how much you would save by using store A, you would simply subtract it =  $1444.50 - $1272 = $172.5

Given this equation:

y = -2/3x +4
What is the slope?

Answers

Answer:

-2/3

Step-by-step explanation:

The equation y = -2/3x + 4 is written in the slope-intercept form,

y = mx + b, in which m is the slope. Comparing the form equation with the given equation, we see that m = -2/3.

Answer: slope = -2/3

Answer:

Slope = - 2/3

Step-by-step explanation:

Step 1:

y = mx + b        Slope Intercept Form

Step 2:

m = Slope

Step 3:

y = - 2/3x + 4        Equation

Answer:

Slope = - 2/3

Step-by-step explanation:

If you turn the 20% into a decimal you get .25 and do the equation .25x 139. This gives you 30.58

If the seventh-grade class has 139 students then 31 students have 31 students.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given that Twenty-two percent of the seventh-grade class at Santa Ana Middle School has blue eyes

The number of students in  seventh-grade class are 139.

We have to find the number of students who has blue eyes in Santa Ana Middle School.

Convert 22% to decimal value.

22/100=0.22

Now multiply 0.22 with 139

0.22×139

30.58=31 students

Hence,  If the seventh-grade class has 139 students then 31 students have 31 students.

A driver’s distance varies directly as the amount of time traveled. After 6 hours, a driver had traveled 390 miles. How far had the driver traveled after 4 hours?

Answers

Answer:

260 miles

Step-by-step explanation:

Answer:

260

Step-by-step explanation:

you would divide 390 by 6 to see how many hours were  per hour, which is 65. You would then multiply it by 4 to see how far they drove in 4 hours, and you get 260. To prove this is right for sure you could multiply 65x2 which is 130 and add 130+260 which would make up the 6 hours and you’d get 390
