9. swimsuit: $22, 5% off, 4% tax

Answer: $0.44

Step-by-step explanation:

Since Marco has $1.31 in his coin bank and he spends 87c to buy a pen, the amount taht will be left with him after he buys the pen will be gotten by subtracting 87cents from $1.31.

Note that 100 cents = $1

Therefore, $1.31 will be = 100 × 1.31 = 131 cents.

Therefore, 131 cents - 87 cents = 44 cents or $0.44

He has $0.44 left

The cost of 8 Concert Tickets is $290

Step-by-step explanation:

Five concert tickets cost = $181.25.

The cost of 8 concert tickets = ?

Now,

181.25 ÷ 5 = 36.25

Here, We get the value of one concert ticket is $36.25

Now, For 8 Concert Tickets

8 × 36.25 = 290

Thus, The cost of 8 Concert Tickets is $290

-TheUnknownScientist

Answer:

$290.

Step-by-step explanation:

$181.25 divided by 5 equals $36.25, therefore, $36.25 x 8 = $290. So, the cost for 8 concert tickets is $290.

Answer:

Step-by-step explanation:

In mathematics, every integer is a rational number, hence a whole number 6 can be written as 6/1. 1/3 ÷ 6 = 1/18 in fraction form. 1/3 ÷ 6 = 0.0556 in decimal form.

Answer:

1/18 or 18 is your answer.

Step-by-step explanation:

Since 1/3 is already in fraction form, we will now turn 6 into fraction form.  Which is 1/6. Now we will put it into the equation 1/3 x 1/6 = 1/18.  The fraction 1/18 can also be 18.  Therefore, 18 or 1/18 is our answer.

Answer:

A

Step-by-step explanation:

since it passes the origin then there is no y intercept, so no plus anything. And the line is going down so its a negative.

The correct answer is A

A) [tex]8(-10)=10(-10)+20[/tex] becomes [tex]-80 = -80[/tex]

B) [tex]8(-35)=10(-35)+20[/tex] becomes [tex]-280 \neq -330[/tex]

C) [tex]8(-23)=10(-23)+20[/tex] becomes [tex]-184 \neq -210[/tex]

D) [tex]8(-40)=10(-40)+20[/tex] becomes [tex]-320\neq -380[/tex]

Answer:

B

Step-by-step explanation:

we are given a equation of a line

we want to figure out the equation of the perpendicular line passes through the (6,5) points

in order to do so

recall that,

[tex] \displaystyle m_{ \text{perpendicular}} = - \frac{1}{m} [/tex]

we got from our given equation that m=2

because equation of a line is y=mx+b

thus

[tex] \displaystyle m_{ \text{perpendicular}} = - \frac{1}{2} [/tex]

remember that, when we want to figure out perpendicular line or parallel line we should the formula given by

[tex] \displaystyle y - y_{1} = m(x - x_{1})[/tex]

since we got our perpendicular m is -½, [tex]x_1=6[/tex] and [tex]y_1=5[/tex], substitute

[tex] \displaystyle y - 5 = - \frac{1}{2} (x - 6)[/tex]

to get the perpendicular equation you should simplify the above equation to y=mx+b form

distribute -½:

[tex] \displaystyle y - 5 = - \frac{1}{2} x + 3[/tex]

add 5 to both sides:

[tex] \displaystyle y = - \frac{1}{2} x + 8[/tex]

hence,

our answer choice is B

Answer:

It's called proportion.

Step-by-step explanation:

The equality of ratios are proportional because like for example 2:3 and 4:9 these two ratios are the same. If you break down 4:9 you will get 2:3. So That's how the term proportional is applied. If we apply these ratio on a triangle they would look the same but just one is small and one is large and we can get it bigger by increasing the ratios. But the difference bwtween the ratios would be same so they are all proportional

There was a little error in  t= -6 when "t"=2, I think you meant when   "r"= 2 when t =-6 so i corrected it before solving.

Answer:r= 7/3

Step-by-step explanation:

Step 1

r varies inversely as t  ,written mathematically can be expressed as

r ∝ 1/t

Introducing the constant of proportionality. K we have

r ∝ 1/t

r=Kt

Step 2

Now when r= 2 when t =-6, we have that

r=Kt

2 = K -6,

k=2/ -6= -1/3

Step 3

Find r when t  =-7

Using our equation,

r=Kt

r= -1/3 x-7

r= 7/3

Answer:

The answer is "12 inches".

Step-by-step explanation:

Please find the image file of the graph.

We know [tex]AE = CF \ and \ EB = FB[/tex] so because the triangle is isosceles.

[tex]EB = 2x, FB = 2x,\ and \ CF = x[/tex] when [tex]AE[/tex] is called by [tex]x[/tex].

We know that [tex]AE = AD = x[/tex] since E and D are tangent points to a circle.

They have [tex]CD = CF = x[/tex] since D and F are tangent points only to circle.

Thus, if the perimeter is 32, the following is the result:

[tex]\to AE + EB + BF + FC + CD + DA = 32\\\\\to x + 2x + 2x + x + x + x = 32\\\\\to 8x = 32\\\\\to x = 4[/tex]

Therefore the length of [tex]BC = BF + FC = 2x + x = 3x = 12\ inches[/tex]

  107/18

Step-by-step explanation:

Your calculator and/or knowledge of trig function values can help you evaluate this.

  = 4/9 +3/4 -9/4 +9 -2

  = 107/18

tan(30°) = 1/√3

tan(45°) = 1

tan(60°) = √3

sin(60°) = cos(30°) = √3/2

i)It ended at  21:13

ii) 440*10/100

44 mins longer

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

110% = 440 minutes (Tuesday journey)

100% = 100/110 x 440

100% = 400 minutes (Monday journey)

Tuesday's journey took 40 minutes longer than Monday's journey.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

On Tuesday the train journey took 7 hours and 20 minutes and began at

13:53.

The time train journey ended.

= 13:53 + 7 hours + 20 minutes

= 13 hours + 53 minutes + 7 hours + 20 minutes

= 20 hours + 73 minutes

= 20 hours + 60 minutes + 13 minutes

= 20 hours + 1 hour + 13 minutes

= 21 hours + 13 minutes

This means,

= 21:13

The train ended the journey at 21:13

Tuesday's time of 7 hours and 20 minutes was 10% more than Monday's journey time.

This means,

Converting into minutes.

7 hours 20 minutes

= 60 x 7 + 20 minutes

= 420 minutes + 20 minutes

= 440 minutes

Monday's journey time.

110% = 440 minutes:

100% = 100/110 x 440

100% = 400 minutes

Thus,

Tuesday's journey took 40 minutes longer than Monday's journey.

All we need to do is add together the amount that can swim.

We do this because all of the numbers added together equals 1, so the parts that are split off represent the percentages (in decimal form) of the total amount of people.
