Answers

Answer:

y = -1/3x

Step-by-step explanation:

The slope of that are perpendicular lines are negative opposites of each other. If a line has a slope of 3, then a line perpendicular to it will have a slope of (-(1/3)).

Use the equation of a line in point-slope form to solve this;

y = mx + b

where "m" is the slope and "b" is the y-intercept.

Substitute the slope in;

y = (-1/3)x + b

Since it passes through the origin, then it has no y-intercept, therefore the equation of the line is;

y = -1/3x

vi. Which one of the following is NOT a perfect square?
a. 625
b. 156
c. 196

Answers

Answer:

b. 156

Step-by-step explanation:

A "perfect square" is the product of an integer that is being multiplied by itself.

Choice a, 625, is a perfect square because it is the product of 25 multiplied by itself.

25 x 25 = 625

Choice b, 156, is not a perfect square because you cannot find any integer that can be multiplied by itself that will result in 156 as a product. Therefore, this is the correct answer.

Choice c, 196, is a perfect square because it is the product of 14 multiplied by itself.

14 x 14 = 196

Three guys rent a hotel room for the night. When they get to the hotel they pay the $30 fee, then go up to their room. Soon the bellhop brings up their bags and gives the lawyers back $5 because the hotel was having a special discount that weekend. So the three lawyers decide to each keep one of the $5 dollars and to give the bellhop a $2 tip. However, when they sat down to tally up their expenses for the weekend they could not explain the following details:

Each one of them had originally paid $10 (towards the initial $30), then each got back $1 which meant that they each paid $9. Then they gave the bellhop a $2 tip. HOWEVER, 3 • $9 + $2 = $29.

The guys couldn't figure out what happened to the other dollar. After all, the three paid out $30 but could only account for $29.

Can you determine what happened?

How long is the truck

Answers

Answer:

Step-by-step explanation:

if the car is 170 inches long

the truck is 85% longer

(170*85)/100=144.50 longer

the truck is 170+144.50=314.50

314.5 inches

100-85=15

170*0.15=25.5

170-25.5=144.5

170+144.5=314.5 inches

in march, Arnold finds a guitar with a price of $650 that he wants to buy, but he only has $300 saved. In September, Arnold has 75% more money saved, and the guitar is on sale for a 30% discount off the original price. The sales tax is 5% of the sale price. Does Arnold have enough money to buy the guitar in September? justify your answer

Answers

Answer:

Yew, he has enough money to buy the guitar in september.

Step-by-step explanation:

300*0.75=225        300+225=525

650*0.35=195            650-195=455

sales tax:    455*0.05=22.75          455+22.75=477.75

Yes , Arnold have enough savings to buy the guitar

Savings amount of Arnold is $ 525 and the price of the guitar is $ 477.75

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the original price of the guitar be = $ 650

Let the initial savings of Arnold be = $ 300

Now , Arnold saved 75 % more than what he actually had

And , the equation will be

So , the new savings of Arnold is = 300 + ( 75/100 ) x 300

The new savings of Arnold is = 300 + ( 300 x 0.75 )

The new savings of Arnold is = 300 + 225

The new savings of Arnold is = $ 525

Now , the price of the guitar is discounted by = 30 %

And , the equation will be

So , the new price of the guitar after discount is = 650 - ( 30/100 ) x 650

The new price of the guitar after discount is = 650 - ( 650 x 0.30 )

The new price of the guitar after discount is = 650 - 195

The new price of the guitar after discount is = $ 455

Now , A sales tax of 5 % is priced on the guitar

And , the equation will be

So , the sale price of the guitar is = 455 + ( 5/100 ) x 455

The sale price of the guitar is = 455 + 22.75

The sale price of the guitar is = $ 477.75

Now , the new savings of Arnold is greater than the sale price of the guitar

$ 525 > $ 477.75

Therefore , Arnold have enough savings to buy the guitar

Hence , Yes , Arnold have enough savings to buy the guitar

Savings amount of Arnold is $ 525 and the price of the guitar is $ 477.75
